Oligosaccharides are polymers with two to ten monosaccharide residues which have sweetener functions and sensory characteristics, in addition to exerting physiological effects on human health. The ones called nondigestible exhibit a prebiotic behavior being fermented by colonic microflora or stimulating the growth of beneficial bacteria, playing roles in the immune system, protecting against cancer, and preventing cardiovascular and metabolic issues. The global prebiotics market is expected to grow around 12.7% in the next 8 years, so manufacturers are developing new alternatives to obtain sustainable and efficient processes for application on a large scale. Most studied examples of biotechnological processes involve the development of new strategies for fructooligosaccharide, galactooligosaccharide, xylooligosaccharide, and mannanooligosaccharide synthesis. Among these, the use of whole cells in fermentation, synthesis of microbial enzymes (β-fructofuranosidases, β-galactosidases, xylanases, and β-mannanases), and enzymatic process development (permeabilization, immobilization, gene expression) can be highlighted, especially if the production costs are reduced by the use of agro-industrial residues or by-products such as molasses, milk whey, cotton stalks, corncobs, wheat straw, poplar wood, sugarcane bagasse, and copra meal. This review comprises recent studies to demonstrate the potential for biotechnological production of oligosaccharides, and also aspects that need more investigation for future applications in a large scale.

Global meat and milk consumption is exponentially increasing due to population growth, urbanization and changes in lifestyle in the developing world. This is an excellent opportunity for developing countries to improve the livestock sector by using technological advances. Biotechnology is one of the avenues for improved production in the "Livestock revolution". Biotechnology developments applied to livestock health, nutrition, breeding and reproduction are improving with a reasonable pace in developing countries. Simple bio-techniques such as artificial insemination have been well implemented in many parts of the developing world. However, advanced technologies including transgenic plant vaccines, marker assisted selection, solid state fermentation for the production of fibrolytic enzymes, transgenic fodders, embryo transfer and animal cloning are confined largely to research organizations. Some developing countries such as Taiwan, China and Brazil have considered the commercialization of biotechnology in the livestock sector. Organized livestock production systems, proper record management, capacity building, objective oriented research to improve farmer's income, collaborations with the developed world, knowledge of the sociology of an area and research on new methods to educate farmers and policy makers need to be improved for the creation and implementation of biotechnology advances in the livestock sector in the developing world.

Fungal biodiversity to biotechnology.

PubMed

Chambergo, Felipe S; Valencia, Estela Y

2016-03-01

Fungal habitats include soil, water, and extreme environments. With around 100,000 fungus species already described, it is estimated that 5.1 million fungus species exist on our planet, making fungi one of the largest and most diverse kingdoms of eukaryotes. Fungi show remarkable metabolic features due to a sophisticated genomic network and are important for the production of biotechnological compounds that greatly impact our society in many ways. In this review, we present the current state of knowledge on fungal biodiversity, with special emphasis on filamentous fungi and the most recent discoveries in the field of identification and production of biotechnological compounds. More than 250 fungus species have been studied to produce these biotechnological compounds. This review focuses on three of the branches generally accepted in biotechnological applications, which have been identified by a color code: red, green, and white for pharmaceutical, agricultural, and industrial biotechnology, respectively. We also discuss future prospects for the use of filamentous fungi in biotechnology application.

de Almeida, Maria Eneida

2015-07-01

Throughout the twentieth century, the biological advance had a closer and closer relation with the strategies of power in search of high technology. From 1970, the manipulation of genetically recombined pathogenic agents was a high technological breakthrough that radically over passed traditional biology and reinforced the war relations of science. The biotechnological revolution started along with new perspectives for the political and military field of science. From this point of the biotechnological development a new paradigm for war, as well as for the sciences of life, was then created and new challenges for International Health in the twenty first century came into scene. Through a historical account related to power, this paper is meant to present the mechanism of articulation existent between science and power and to contribute for understanding how the military field is naturally inserted in the biotechnological development which, in its essence, produces biotechnologies for civil and military uses.

Biotechnology and genetic engineering in the new drug development. Part I. DNA technology and recombinant proteins.

Pharmaceutical biotechnology has a long tradition and is rooted in the last century, first exemplified by penicillin and streptomycin as low molecular weight biosynthetic compounds. Today, pharmaceutical biotechnology still has its fundamentals in fermentation and bioprocessing, but the paradigmatic change affected by biotechnology and pharmaceutical sciences has led to an updated definition. The biotechnology revolution redrew the research, development, production and even marketing processes of drugs. Powerful new instruments and biotechnology related scientific disciplines (genomics, proteomics) make it possible to examine and exploit the behavior of proteins and molecules. Recombinant DNA (rDNA) technologies (genetic, protein, and metabolic engineering) allow the production of a wide range of peptides, proteins, and biochemicals from naturally nonproducing cells. This technology, now approximately 25 years old, is becoming one of the most important technologies developed in the 20(th) century. Pharmaceutical products and industrial enzymes were the first biotech products on the world market made by means of rDNA. Despite important advances regarding rDNA applications in mammalian cells, yeasts still represent attractive hosts for the production of heterologous proteins. In this review we describe these processes.

Mandenius, Carl-Fredrik; Björkman, Mats

2010-05-01

Traditionally, biotechnology design has focused on the manufacture of chemicals and biologics. Still, a majority of biotechnology products that appear on the market today is the result of mechanical-electric (mechatronic) construction. For these, the biological components play decisive roles in the design solution; the biological entities are either integral parts of the design, or are transformed by the mechatronic system. This article explains how the development and production engineering design principles used for typical mechanical products can be adapted to the demands of biotechnology products, and how electronics, mechanics and biology can be integrated more successfully. We discuss three emerging areas of biotechnology in which mechatronic design principles can apply: stem cell manufacture, artificial organs, and bioreactors. Copyright 2010 Elsevier Ltd.

The Unfinished Revolution: Einstein's revenge

Beichler, James

2007-04-01

Thomas Kuhn defined the characteristics of scientific revolutions based upon his knowledge of the first and second Scientific Revolutions. He concluded that such revolutions are the result of crises in science. However, he missed some important clues of how revolutions develop. Instead of looking at crises, we should look at the major trends in scientific and human thought prior to the revolutions and then we could gain a better understanding of how scientific revolutions emerge from the normal course of scientific evolution. Instead of defining revolutions by the crises that precede them, revolutions actually emerge from the successes of previous science while each revolution contains the seeds for the next revolution that follows. These seeds eventually grow into the crises that trigger revolutions. Under these circumstances, it can be shown that the space-time revolution of relativity theory was never completed, thus laying the foundations for the next revolution in science. Knowing this, we can determine if we have we already entered the pre-revolutionary period of the Third Scientific Revolution.

The Space Biotechnology and Commercial Applications grant was funded by NASA's Kennedy Space Center in FY 2002 to provide dedicated biotechnology and agricultural research focused on the regeneration of space flight environments with direct parallels in Earth-based applications for solving problems in the environment, advances in agricultural science, and other human support issues amenable to targeted biotechnology solutions. This grant had three project areas, each with multiple tasks. They are: 1) Space Agriculture and Biotechnology Research and Education, 2) Integrated Smart Nanosensors for Space Biotechnology Applications, and 3) Commercial Applications. The Space Agriculture and Biotechnology Research and Education (SABRE) Center emphasized the fundamental biology of organisms involved in space flight applications, including those involved in advanced life support environments because of their critical role in the long-term exploration of space. The SABRE Center supports research at the University of Florida and at the Space Life Sciences Laboratory (SLSL) at the Kennedy Space Center. The Integrated Smart Nanosensors for Space Biotechnology Applications component focused on developing and applying sensor technologies to space environments and agricultural systems. The research activities in nanosensors were coordinated with the SABRE portions of this grant and with the research sponsored by the NASA Environmental Systems Commercial Space Technology Center located in the Department of Environmental Engineering Sciences. Initial sensor efforts have focused on air and water quality monitoring essential to humans for living and working permanently in space, an important goal identified in NASA's strategic plan. The closed environment of a spacecraft or planetary base accentuates cause and effect relationships and environmental impacts. The limited available air and water resources emphasize the need for reuse, recycling, and system monitoring. It is essential to

Chinese hamster ovary (CHO) cells are the primary factories for biopharmaceuticals because of their capacity to correctly fold and post-translationally modify recombinant proteins compatible with humans. New opportunities are arising to enhance these cell factories, especially since the CHO-K1 cell line was recently sequenced. Now, the CHO systems biology era is underway. Critical 'omics data sets, including proteomics, transcriptomics, metabolomics, fluxomics, and glycomics, are emerging, allowing the elucidation of the molecular basis of CHO cell physiology. The incorporation of these data sets into mathematical models that describe CHO phenotypes will provide crucial biotechnology insights. As 'omics technologies and computational systems biology mature, genome-scale approaches will lead to major innovations in cell line development and metabolic engineering, thereby improving protein production and bioprocessing.

1994-01-01

Funding for biomedical research has shifted from government to the private sector. One reason is rapid expansion in the number and strength of U.S. biotechnology companies, which collectively spend more than $6 billion a year on biomedical research. Most of these companies are not yet profitable and therefore depend on flows of capital from private investors, Wall Street, and large pharmaceutical company collaborations. Investment in the new drugs, devices, and vaccines in this pipeline is sensitive to signals emanating from the debate on health care reform, suggesting that new federal policy will have a major impact on steering the type of innovation to emerge in the future.

This study questions the presumed relation between formal schooling and scientific literacy about biotechnologies. Comparing science and nonscience majors' knowledge of and attitudes toward biotechnological applications, conclusions are drawn if their formal learnings improve pupils' understandings of and attitudes toward biotechnology applications. Sample of the study consists of 403 undergraduate and graduate students, 198 nonscience, and 205 science majors. The Biotechnology Knowledge Questionnaire and the Biotechnology Attitude Questionnaire were administered. Descriptive statistics (mean and percentages), t test, and correlations were used to examine the participants' knowledge of biotechnology and attitudes toward biotechnological applications and differences as regards their majors. Although the science majors had higher knowledge and attitude scores than the nonscience majors, it is not possible to say that they have sufficient knowledge of biotechnologies. Besides, the participants' attitudes toward biotechnological applications were not considerably related to their knowledge of biotechnology. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):115-125, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

The relationship of knowledge, attitudes and perceptions regarding biotechnology in college students

NASA Astrophysics Data System (ADS)

Sohan, Donna Elizabeth

Biotechnology is the latest in a series of technological innovations that have revolutionized such fields as agriculture and the health sciences. However, along with the benefits of biotechnology are concerns. For biotechnology's potential to be realized, it must be accepted on public and governmental levels. Although many studies focus on adult consumer attitudes, it will be the students of today who will be the consumers and leaders of tomorrow. Therefore, this study focused on the knowledge, attitudes, and perceptions of college students regarding biotechnology. More than 3,000 undergraduate students were surveyed from a variety of undergraduate courses at Texas A&M University in College Station, Texas during the 1997-1998 academic year. Information sought included students' knowledge regarding recent applications of biotechnology, demographic information, and their agreement or disagreement with statements regarding different aspects and applications of biotechnology. This study found that despite a low awareness or knowledge of biotechnology, students were accepting of specific applications or products of biotechnology. Those applications or products viewed as beneficial without involving animals had the highest acceptance levels. A majority of the students identified mass media as their major source of biotechnology while also indicating a high level of distrust of the media. Students also indicated that biotechnology information is needed and that such information is appropriate for high school students. Relationships between knowledge and attitudes were also investigated. A greater knowledge level correlated with a more favorable view of biotechnology. In addition, relationships between demographic variables such as gender and race were investigated. Individuals who identified themselves as scientists were found more accepting of biotechnology while females in general were found less accepting. Females majoring in education were found to be the least

The International Space Station (ISS) will support several facilities dedicated to scientific research. One such facility, the Biotechnology Facility (BTF), is sponsored by the Microgravity Sciences and Applications Division (MSAD) and developed at NASA's Johnson Space Center. The BTF is scheduled for delivery to the ISS via Space Shuttle in April 2005. The purpose of the BTF is to provide: (1) the support structure and integration capabilities for the individual modules in which biotechnology experiments will be performed, (2) the capability for human-tended, repetitive, long-duration biotechnology experiments, and (3) opportunities to perform repetitive experiments in a short period by allowing continuous access to microgravity. The MSAD has identified cell culture and tissue engineering, protein crystal growth, and fundamentals of biotechnology as areas that contain promising opportunities for significant advancements through low-gravity experiments. The focus of this coordinated ground- and space-based research program is the use of the low-gravity environment of space to conduct fundamental investigations leading to major advances in the understanding of basic and applied biotechnology. Results from planned investigations can be used in applications ranging from rational drug design and testing, cancer diagnosis and treatments and tissue engineering leading to replacement tissues.

2014-08-01

While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

Agricultural biotechnology, including the generation of genetically modified food crops, has been the subject of much controversy over the last few years. Initially serving the basic needs of farmers, Ag Biotech has more recently gained much appeal for its opportunities with respect to both the nutritional and pharmaceutical sciences. The following review describes a number of recently approved patents that could have direct implications for the field of medicine. Topics range from the development of pharmaceuticals in plants using hairy roots or virus expression vectors, to the role of epigenetics for improving the nutritional value of food crops. Many of these patents were developed by smaller companies or publically funded research institutes, disproving the perception that intellectual property in Ag Biotech is restricted to only large multinational corporations. The review concludes with a discussion of the future of these technologies in the face of the current negative political climate.

2005-12-01

Biotechnology-derived food crops are currently being developed in Malaysia mainly for disease resistance and improved post harvest quality. The modern biotechnology approach is adopted because of its potential to overcome constraints faced by conventional breeding techniques. Research on the development of biotechnology-derived papaya, pineapple, chili, passion fruit, and citrus is currently under way. Biotechnology-derived papaya developed for resistance to papaya ringspot virus (PRSV) and improved postharvest qualities is at the field evaluation stage. Pineapple developed for resistance to fruit black heart disorder is also being evaluated for proof-of-concept. Other biotechnology-derived food crops are at early stages of gene cloning and transformation. Activities and products involving biotechnology-derived crops will be fully regulated in the near future under the Malaysian Biosafety Law. At present they are governed only by guidelines formulated by the Genetic Modification Advisory Committee (GMAC), Malaysia. Commercialization of biotechnology-derived crops involves steps that require GMAC approval for all field evaluations and food-safety assessments before the products are placed on the market. Public acceptance of the biotechnology product is another important factor for successful commercialization. Understanding of biotechnology is generally low among Malaysians, which may lead to low acceptance of biotechnology-derived products. Initiatives are being taken by local organizations to improve public awareness and acceptance of biotechnology. Future research on plant biotechnology will focus on the development of nutritionally enhanced biotechnology-derived food crops that can provide more benefits to consumers.

Human rights in the world of the genetic revolution.

Castro-Rios, A

1999-01-01

The Biotechnological Revolution provides enormous possibilities to human development (nutrition, medicine, industry), while at the same time, creates social-ethical apprehensions due to the dangers to Human Rights that an improper use could generate. In this respect, Human Rights are presented as the "religion" of our time: accepted by all, although not equally practised. These rights, classified in the Universal Declaration of the United Nations, are the terms which society uses to ponder the ethical peformance of individuals and organizations. Harmonisation between Biotechnology and Human Rights should be based on a continuous social debate in which the principles that contribute to the respect of the human's essential nature should arise. As a starting point, considerations concerning the repercussions which the different genetic techniques have on each of the individually considered Human Rights, i.e. on dignity, equality, freedom, the right to health, to intimacy or to a worthy environment should be developed. Moreover, an international vision of the problem should be imposed since it should be remembered that initiatives that avoid attacks on Human Rights are either taken internationally or are condemned to failure. The following work was not written to give practical solutions to ethical conflicts but simply to consider some of the aspects which can create controversy in the search for a coherent future for human nature.

For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would "always be five years away." This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market, they are growing rapidly. The four key technologies this report focuses on are: onshore wind power, polysilicon photovoltaic modules, LED lighting, and electric vehicles.

In this review, we aim to explore the potential of microalgal biodiversity and ecology for biotechnological use. A deeper exploration of the biodiversity richness and ecophysiological properties of microalgae is crucial for enhancing their use for applicative purposes. After describing the actual biotechnological use of microalgae, we consider the multiple faces of taxonomical, morphological, functional and ecophysiological biodiversity of these organisms, and investigate how these properties could better serve the biotechnological field. Lastly, we propose new approaches to enhancing microalgal growth, photosynthesis, and synthesis of valuable products used in biotechnological fields, mainly focusing on culture conditions, especially light manipulations and genetic modifications.

A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits.

Biotechnology to harness the benefits of dietary phenolics; focus on Lamiaceae.

PubMed

Shetty, K

1997-09-01

Phytochemicals from herbs and fermented legumes are excellent dietary sources of phenolic metabolites. These phenolics have importance not only as food preservatives but increasingly have therapeutic and pharmaceutical applications. The long-term research objecitves of the food biotechnology program at the University of Massachusetts are to elucidate the molecular and physiological mechanisms associated with synthesis of important health-related, therapeutic phenolic metabolites in food-related plants and fermented plant foods. Current efforts focus on elucidation of the role of the proline-linked pentose phosphate pathway in regulating the synthesis of anti-inflammatory compound, rosmarinic acid (RA). Specific aims of the current research efforts are: (i) To develop novel tissue culture-based selection techniques to isolate high RA-producing, shoot-based clonal lines from genetically heterogeneous, cross-pollinating species in the family Lamiaceae; (ii) To target genetically uniform, regenerated shoot-based clonal lines for: (a) preliminary characterization of key enzymes associated with the pentose phosphate pathway and linked to RA synthesis; (b) development of genetic transformation techniques for subsequent engineering of metabolic pathways associated with RA synthesis. These research objectives have substantial implications for harnessing the genetic and biochemical potential of genetically heterogeneous, food-related medicinal plant species. The success of this research also provides novel methods and strategies to gain access to metabolic pathways of pharmaceutically important metabolites from ginger, curcuma, chili peppers, melon or other food-related species with novel phenolics.

Current challenges and future perspectives of plant and agricultural biotechnology.

Advances in understanding plant biology, novel genetic resources, genome modification, and omics technologies generate new solutions for food security and novel biomaterials production under changing environmental conditions. New gene and germplasm candidates that are anticipated to lead to improved crop yields and other plant traits under stress have to pass long development phases based on trial and error using large-scale field evaluation. Therefore, quantitative, objective, and automated screening methods combined with decision-making algorithms are likely to have many advantages, enabling rapid screening of the most promising crop lines at an early stage followed by final mandatory field experiments. The combination of novel molecular tools, screening technologies, and economic evaluation should become the main goal of the plant biotechnological revolution in agriculture.

Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customized which further can be applied to achieve required solubility, biodegradability, diagnosis and other applications. Given the physicochemical variability of the dendrimers and their hybrids, this review attempts to discuss a full spectrum of recent advances and strides made by these "perfectly designed structures". An extensive biotech/biomimicry application profiling of dendrimers is provided with focus on complex archetypical designs such as protein biomimicry (angiogenic inhibitors, regenerative hydroxyapatite and collagen) and biotechnology applications. In terms of biotechnological advances, dendrimers have provided distinctive advantages in the fields of biocatalysis, microbicides, artificial lights, mitochondrial function modulation, vaccines, tissue regeneration and repair, antigen carriers and even biosensors. In addition, this review provides overview of the extensive chemo-functionalization opportunities available with dendrimers which makes them a perfect candidate for forming drug conjugates, protein hybrids, bio mimics, lipidic derivatives, metal deposits and nanoconjugates thereby making them the most multifunctional platforms for diverse biotechnological applications.

Why the Pre-Copernican Cosmological Revolution Was Not a Revolution?

NASA Astrophysics Data System (ADS)

Pacholczyk, A. G.

The 'scientific component' of the Copernican cosmological revolution followed a seemingly minor local structural change (consisting of the transposition of the Earth and the Sun), initially not affecting the global Platonic-Aristotelian spherical symmetry of the Universe and the general arrangement of astronomical bodies at sufficiently large distances from its center. Yet this change resulted in a rich 'ideological component' of the Copernican revolution in the Popperian sense; the importance of this ideological component is generally regarded as a consequence of the tensions arising from apparent contradictions between the new cosmos and several Scriptural passages (as if the previous Platonic-Aristotelian cosmos were in perfect agreement with the Scriptures, which certainly was not the case). The scientific component of the pre-Copernican cosmological revolution (replacing the plane-parallel scriptural cosmos with the spherically symmetric non-scriptural Universe of Plato and Aristotle), was a major global change in the large-scale structure of the Universe. This change took place at different times in different places in Christendom, and was by no means ideologically revolutionary: the pre-Copernican revolution had a very insignificant 'ideological component'. In this paper, after examining this transition in more detail, we shall ask the pertinent question: why did the pre-Copernican cosmological revolution not have any significant 'ideological component'? If the God-created Universe could be depicted in the opinion of the majority of Church Fathers and Schoolmen by the (non-scriptural) spherically symmetric Platonic or Aristotelian model as well as by the (scriptural) tabernacular Babylonian model, then why couldn't it be described just as well in the opinion of 17th century churchmen by the (also non-scriptural) Copernican model? The paper suggests that the tentative answers to these questions are provided by different anthropocentric ramifications of

Star scientists and institutional transformation: patterns of invention and innovation in the formation of the biotechnology industry.

PubMed

Zucker, L G; Darby, M R

The most productive ("star") bioscientists had intellectual human capital of extraordinary scientific and pecuniary value for some 10-15 years after Cohen and Boyer's 1973 founding discovery for biotechnology [Cohen, S., Chang, A., Boyer, H. & Helling, R. (1973) Proc. Natl. Acad. Sci. USA 70, 3240-3244]. This extraordinary value was due to the union of still scarce knowledge of the new research techniques and genius and vision to apply them in novel, valuable ways. As in other sciences, star bioscientists were very protective of their techniques, ideas, and discoveries in the early years of the revolution, tending to collaborate more within their own institution, which slowed diffusion to other scientists. Close, bench-level working ties between stars and firm scientists were needed to accomplish commercialization of the breakthroughs. Where and when star scientists were actively producing publications is a key predictor of where and when commercial firms began to use biotechnology. The extent of collaboration by a firm's scientists with stars is a powerful predictor of its success: for an average firm, 5 articles coauthored by an academic star and the firm's scientists result in about 5 more products in development, 3.5 more products on the market, and 860 more employees. Articles by stars collaborating with or employed by firms have significantly higher rates of citation than other articles by the same or other stars. The U.S. scientific and economic infrastructure has been particularly effective in fostering and commercializing the bioscientific revolution. These results let us see the process by which scientific breakthroughs become economic growth and consider implications for policy.

A Short (Personal) Future History of Revolution 2.0.

PubMed

Spellman, Barbara A

2015-11-01

Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science. © The Author(s) 2015.

Plastid biotechnology for crop production: present status and future perspectives

PubMed Central

Daniell, Henry

2012-01-01

The world population is expected to reach an estimated 9.2 billion by 2050. Therefore, food production globally has to increase by 70% in order to feed the world, while total arable land, which has reached its maximal utilization, may even decrease. Moreover, climate change adds yet another challenge to global food security. In order to feed the world in 2050, biotechnological advances in modern agriculture are essential. Plant genetic engineering, which has created a new wave of global crop production after the first green revolution, will continue to play an important role in modern agriculture to meet these challenges. Plastid genetic engineering, with several unique advantages including transgene containment, has made significant progress in the last two decades in various biotechnology applications including development of crops with high levels of resistance to insects, bacterial, fungal and viral diseases, different types of herbicides, drought, salt and cold tolerance, cytoplasmic male sterility, metabolic engineering, phytoremediation of toxic metals and production of many vaccine antigens, biopharmaceuticals and biofuels. However, useful traits should be engineered via chloroplast genomes of several major crops. This review provides insight into the current state of the art of plastid engineering in relation to agricultural production, especially for engineering agronomic traits. Understanding the bottleneck of this technology and challenges for improvement of major crops in a changing climate are discussed. PMID:21437683

The dual Green Revolutions in South Korea: reforestation and agricultural revolution under the authoritarian regime.

PubMed

Moon, Manyong

2012-01-01

In South Korea, the Green Revolution has been commonly understood as the development and dissemination of new rice varieties ('Tongil' rice) and the rapid increase of rice yield in the 1970s. However, revolutionary success in agriculture was not the only green revolution South Korea experienced; another green revolution lay in the success of reforestation projects. In the 1970s, South Korea's forest greening was closely related to its agricultural revolution in several ways. Therefore, South Korea's Green Revolution was an intrinsically linked double feature of agriculture and forestry. This two-pronged revolution was initiated by scientific research - yet accomplished by the strong administrative mobilization of President Park Chung Hee's regime. The process of setting goals and meeting them through a military-like strategy in a short time was made possible under the authoritarian regime, known as 'Yushin', though the administration failed to fully acknowledge scientific expertise in the process of pushing to achieve goals.

Biotechnological Applications of Microbial (Per)chlorate Reduction.

Wang, Ouwei; Coates, John D

2017-11-24

While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration. Although the obvious application of these metabolisms lies in the bioremediation and attenuation of (per)chlorate in contaminated environments, a diversity of alternative and innovative biotechnological applications has been proposed based on the unique metabolic abilities of dissimilatory (per)chlorate-reducing bacteria (DPRB). This is fueled in part by the unique ability of these organisms to generate molecular oxygen as a transient intermediate of the central pathway of (per)chlorate respiration. This ability, along with other novel aspects of the metabolism, have resulted in a wide and disparate range of potential biotechnological applications being proposed, including enzymatic perchlorate detection; gas gangrene therapy; enhanced xenobiotic bioremediation; oil reservoir bio-souring control; chemostat hygiene control; aeration enhancement in industrial bioreactors; and, biogenic oxygen production for planetary exploration. While previous reviews focus on the fundamental science of microbial (per)chlorate reduction (for example see Youngblut et al., 2016), here, we provide an overview of the emerging biotechnological applications of (per)chlorate respiration and the underlying organisms and enzymes to environmental and biotechnological industries.

The 20th century has been a century of scientific revolutions for many disciplines: quantum mechanics in physics, the atomic approach in chemistry, the nonlinear revolution in mathematics, the introduction of statistical physics. The major breakthroughs in these disciplines had all occurred by about 1930. In contrast, the revolutions in the so-called natural sciences, that is in the earth sciences and in biology, waited until the last half of the century. These revolutions were indeed late, but they were no less deep and drastic, and they occurred quite suddenly. Actually, one can say that not one but three revolutions occurred in the earth sciences: in plate tectonics, planetology and the environment. They occurred essentially independently from each other, but as time passed, their effects developed, amplified and started interacting. These effects continue strongly to this day.

The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students' biotechnology attitudes.

The Mexican Revolution and health care or the health of the Mexican Revolution.

PubMed

Horn, J J

1985-01-01

Despite a victorious social revolution, a self-proclaimed "revolutionary" government, and a significant post-war economic growth, Mexico has not achieved a just or equitable social system. The Mexican Revolution led to the emergence of a new bureaucratic class whose "trickle-down" development strategy sacrificed social welfare to capital accumulation. Mexican morbidity and mortality patterns resemble those of more impoverished developing nations without revolutionary experience. The patterns of health care in Mexico reflect inequities and contradictions in the society and economy at large and flow from the erosion of the egalitarian aims of the revolution concomitant with the expansion of capitalism and the concentration of the benefits of "modernization" in the hands of privileged elites. Mexico's health problems are symptomatic of a general socio-economic malaise which questions the legitimacy of the Revolution.

Controversial medical and agri-food biotechnology: a cultivation analysis.

PubMed

Bauer, Martin W

2002-04-01

Whether biotechnology is one or several developments is not clear. Once distinctions are required, the question is: Which one prevails? When the good, the bad, and the ugly settle, where do they fall? Evaluation implies distinction, and representation drives attitude. The controversies over biotechnology are fertile ground on which to study these issues. The imports of genetically modified (GM) soya into Europe in 1996-97 and the cloning of Dolly the sheep from adult cells in 1997 changed the symbolic environment for genetic engineering. The ensuing public controversies came to focus mainly on field trials of GM crops and food labeling. This paper will explore the relationship between quality press coverage and public perception, in particular the cultivation of the contrast between "desirable" biomedical (RED) and "undesirable" agri-food (GREEN) biotechnology in Britain. The argument draws on a systematic analysis of the British press coverage of biotechnology from 1973 to 1999 and analysis of public perceptions in 1996 and 1999. The paper concludes that the debate over GM crops and food ingredients fostered the RED-GREEN contrast among the newspaper-reading public, thereby shielding RED biotechnology from public controversy, and ushered in a realignment of the regulatory framework in 2000.

Healthcare biotechnology in India.

Biotechnology in India has made great progress in the development of infrastructure, manpower, research and development and manufacturing of biological reagents, biodiagnostics, biotherapeutics, therapeutic and, prophylactic vaccines and biodevices. Many of these indigenous biological reagents, biodiagnostics, therapeutic and prophylactic vaccines and biodevices have been commercialized. Commercially when biotechnology revenue has reached $25 billions in the U.S. alone in 2000 excluding the revenues of biotech companies that were acquired by pharmaceutical companies, India has yet to register a measurable success. The conservative nature and craze of the Indian Industry for marketing imported biotechnology products, lack of Government support, almost non-existing national healthcare system and lack of trained managers for marketing biological and new products seem to be the important factors responsible for poor economic development of biotechnology in India. With the liberalization of Indian economy, more and more imported biotechnology products will enter into the Indian market. The conditions of internal development of biotechnology are not likely to improve in the near future and it is destined to grow only very slowly. Even today biotechnology in India may be called to be in its infancy.

The second part of the biotechnology awareness study focused on health sciences libraries and how well they are meeting the needs of biotechnologists working in the study's nine medical centers. A survey was conducted over a three-month period to assess the demand for biotechnology-related reference services at nine libraries and the sources the librarians used to answer the questions. Data on monographic and current serial holdings were also collected. At the end of the survey period, librarians were asked for their perceptions about biotechnology research at their institutions and in their geographic areas. Their responses were compared to the responses the scientists at the nine schools gave to the same or similar questions. Results showed few biotechnology-related reference questions were asked of the librarians. The recorded questions dealt with a range of biotechnology subjects. MEDLINE was used to answer 77% of the questions received during the survey period. More detailed notes in MeSH and a guide to online searching for biotechnology topics were suggested by the librarians as ways to improve reference service to this group of researchers. Journal collections were generally strong, with libraries owning from 50% to 87% of the titles on a core list of biotechnology journals compiled for this study. All libraries subscribed to the five titles most often cited by the scientists surveyed. Generally, librarians were unaware of the biotechnology-related research being done on their campuses or in their geographic areas. PMID:1998819

Biotechnological processes are promising alternatives to petrochemical routes for overcoming the challenges of resource depletion in the future in a sustainable way. The strategies of white biotechnology allow the utilization of inexpensive and renewable resources for the production of a broad range of bio-based compounds. Renewable resources, such as agricultural residues or residues from food production, are produced in large amounts have been shown to be promising carbon and/or nitrogen sources. This chapter focuses on the biotechnological production of lactic acid, acrylic acid, succinic acid, muconic acid, and lactobionic acid from renewable residues, these products being used as monomers for bio-based material and/or as food supplements. These five acids have high economic values and the potential to overcome the "valley of death" between laboratory/pilot scale and commercial/industrial scale. This chapter also provides an overview of the production strategies, including microbial strain development, used to convert renewable resources into value-added products.

Te Momo, O H Fiona

2007-09-01

In Aotearoa (New Zealand), the government funded studies on communicating biotechnology to different sectors in the community from 2003 to 2006. Subsequently, a researcher covering the Māori sector performed a content analysis of data gathered in the community. Qualitative analysis methods included examining text from participant interviews, focus groups, government documents, newspapers, Internet sites, and current literature. Content was coded by identifying common themes in the English and the Māori language. Words like genetic modification (GM), genetic engineering (GE), and biotechnology were explained to provide a basic understanding between the communities and researcher. The terminology applied in the research was essential to achieve communication between the researcher and the community. The resultant themes represented seven views to interpret the communities association with biotechnology: purist Māori, religious Māori, anti Māori, pro Māori, no Māori, uncertain Māori, and middle Māori views. The themes are taken from the analysis of data compiled after 3 years of completing different stages of a research project. The views indicate that a common understanding can be achieved in the diverse range of Māori tribal communities providing those communicating biotechnology can identify the view and interpretations communities associate with biotechnology. This knowledge is essential for government agencies, researchers, community practitioners, scientist, and businesses that desire to dialogue with Māori communities in the language of biotechnology.

The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

The State Planning Organization (SPO) in 1988 defined biotechnology and the scientific fields. Moreover, it put forward an institutional framework and suggested priority areas for research and development. Turkey has been researching and investing in biotechnology for almost four decades. This review covers the development of science and technology policy with its history, consensus and consequences, bio-industries in Turkey, and research activities in biotechnology at Turkish Universities. Details are provided by the research groups in response to a common request for information on their activities and major publications in the field. The information provided has been grouped under thematic topics within the broad theme of biotechnology, and summarized within these topics. Although many aspects of biotechnological research are being pursued in Turkey, it appears that the most common research activities of the field are in fermentation processes, environmental biotechnology, and biomedical engineering.

Steele, Frances A.

Agriculture, industry and medicine are being altered by new biological technologies. Today's students are the citizens who will make decisions about associated ethical issues. They need to have the knowledge that will enable them to make informed choices. Hence biotechnology has an important place in science education. The aims of the research were to: 1. describe the state of biotechnology teaching in NSW; 2. determine whether teachers in NSW do not teach biotechnology because they do not have the necessary knowledge and experience; 3. identify other reasons why NSW teachers choose not to teach biotechnology; 4. describe problems encountered in teaching biotechnology in NSW; 5. suggest ways in which the problems encountered in the teaching of biotechnology can be overcome. Quantitative and qualitative methods were used in a complementary way to investigate these aims. In a sample of teachers surveyed, many reported that they chose not to teach biotechnology because they did not have adequate knowledge and experience. Other obstacles were identified. These were: 1. the difficulty of the subject matter; 2. the lack of practical work; 3. lack of a program for biotechnology in junior science. The results of this trial suggested that a biotechnology unit should be developed in collaboration with the teacher and that time needs to be made available for school based program development.

2011-01-01

Computational fluid dynamics (CFD) is well established as a tool of choice for solving problems that involve one or more of the following phenomena: flow of fluids, heat transfer,mass transfer, and chemical reaction. Unit operations that are commonly utilized in biotechnology processes are often complex and as such would greatly benefit from application of CFD. The thirst for deeper process and product understanding that has arisen out of initiatives such as quality by design provides further impetus toward usefulness of CFD for problems that may otherwise require extensive experimentation. Not surprisingly, there has been increasing interest in applying CFD toward a variety of applications in biotechnology processing in the last decade. In this article, we will review applications in the major unit operations involved with processing of biotechnology products. These include fermentation,centrifugation, chromatography, ultrafiltration, microfiltration, and freeze drying. We feel that the future applications of CFD in biotechnology processing will focus on establishing CFD as a tool of choice for providing process understanding that can be then used to guide more efficient and effective experimentation. This article puts special emphasis on the work done in the last 10 years. © 2011 American Institute of Chemical Engineers

The impact of biotechnological advances on the future of US bioenergy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Davison, Brian H.; Brandt, Craig C.; Guss, Adam M.

Modern biotechnology has the potential to substantially advance the feasibility, structure, and efficiency of future biofuel supply chains. Advances might be direct or indirect. A direct advance would be improving the efficiency of biochemical conversion processes and feedstock production. Direct advances in processing may involve developing improved enzymes and bacteria to convert lignocellulosic feedstocks to ethanol. Progress in feedstock production could include enhancing crop yields via genetic modification or the selection of specific natural variants and breeds. Other direct results of biotechnology might increase the production of fungible biofuels and bioproducts, which would impact the supply chain. Indirect advances mightmore » include modifications to dedicated bioenergy crops that enable them to grow on marginal lands rather than land needed for food production. This study assesses the feasibility and advantages of near-future (10-year) biotechnological developments for a US biomass-based supply chain for bioenergy production. We assume a simplified supply chain of feedstock, logistics and land use, conversion, and products and utilization. The primary focus is how likely developments in feedstock production and conversion technologies will impact bioenergy and biofuels in the USA; a secondary focus is other innovative uses of biotechnologies in the energy arenas. The assessment addresses near-term biofuels based on starch, sugar, and cellulosic feedstocks and considers some longer-term options, such as oil-crop and algal technologies.« less

Agriculture, industry and medicine are being altered by new biotechnologies. Biotechnology education is important because todays students and citizens will make decisions about the development and application of these new molecular biologies. This article reports an investigation of the teaching of biotechnology in an Australian state, New South Wales (NSW). In NSW few students were electing to answer examination questions related to biotechnology, suggesting that few students were studying the topic. This study looks at why electives relating to biotechnology are chosen or not chosen by students and teachers, with the intention of developing a greater understanding of the requirements for provision of a successful unit of study in this subject. Data was obtained through a survey of secondary science teachers, interviews with teachers and two case studies of the teaching of a biotechnology unit. Teachers reported a range of obstacles to the teaching of biotechnology including the difficulty of the subject matter and a lack of practical work that was suited to the content of the teaching unit. If biotechnology is worth learning in school science, then further research is needed to identify ways to promote the effective teaching of this topic, which teachers regard as important for, and interesting to, students but which most teachers choose not to teach.

Biotechnology System Facility: Risk Mitigation on Mir

NASA is working with its international partners to develop space vehicles and facilities that will give researchers the opportunity to conduct scientific investigations in space. As part of this activity, NASA's Biotechnology Cell Science Program (BCSP) at the Johnson Space Center (JSC) is developing a world-class biotechnology laboratory facility for the International Space Station (ISS). This report describes the BCSP, including the role of the BTS. We identify the purpose and objectives of the BTS and a detailed description of BTS facility design and operational concept, BTS facility and experiment-specific hardware, and scientific investigations conducted in the facility. We identify the objectives, methods, and results of risk mitigation investigations of the effects of microgravity and cosmic radiation on the BTS data acquisition and control system. These results may apply to many other space experiments that use commercial, terrestrial-based data acquisition technology. Another focal point is a description of the end-to-end process of integrating and operating biotechnology experiments on a variety of space vehicles. The identification of lessons learned that can be applied to future biotechnology experiments is an overall theme of the report. We include a brief summary of the science results, but this is not the focus of the report. The report provides some discussion on the successful 130-day tissue engineering experiment performed in BTS on Mir and describes a seminal gene array investigation that identified a set of unique genes that are activated in space.

How Japanese students reason about agricultural biotechnology.

Maekawa, Fumi; Macer, Darryl

2004-10-01

Many have claimed that education of the ethical issues raised by biotechnology is essential in universities, but there is little knowledge of its effectiveness. The focus of this paper is to investigate how university students assess the information given in class to make their own value judgments and decisions relating to issues of agricultural biotechnology, especially over genetically modified organisms (GMOs). Analysis of homework reports related with agricultural biotechnology after identification of key concepts and ideas in each student report is presented. The ideas were sorted into different categories. The ideas were compared with those in the reading materials using the same categories. These categories included: concern about affects on humans, affects on the environment, developing countries and starvation, trust in industry, responsibility of scientists, risk perception, media influence, need for (international) organizations or third parties, and information dissemination. What was consistent through the different years was that more than half of the students took a "neutral" position. A report was scored as "neutral" when the report included both the positive and negative side of an issue, or when the student could not make a definite decision about the use of GMOs and GM food. While it may be more difficult to defend a strong ''for" or "against" position, some students used logical arguments successfully in doing so. Sample comments are presented to depict how Japanese students see agricultural technology, and how they value its application, with comparisons to the general social attitudes towards biotechnology.

The emerging international regulatory framework for biotechnology.

PubMed

Komen, John

2012-01-01

Debate about the potential risks of genetically modified organisms (GMOs) to the environment or human health spurred attention to biosafety. Biosafety is associated with the safe use of GMOs and, more generally, with the introduction of non-indigenous species into natural or managed ecosystems. Biosafety regulation--the policies and procedures adopted to ensure the environmentally safe application of modern biotechnology--has been extensively discussed at various national and international forums. Much of the discussion has focused on developing guidelines, appropriate legal frameworks and, at the international level, a legally binding international biosafety protocol--the Cartagena Protocol on Biosafety. The Protocol is one among various international instruments and treaties that regulate specific aspects relevant to agricultural biotechnology. The present article presents the main international instruments relevant to biosafety regulation, and their key provisions. While international agreements and standards provide important guidance, they leave significant room for interpretation, and flexibility for countries implementing them. Implementation of biosafety at the national level has proven to be a major challenge, particularly in developing countries, and consequently the actual functioning of the international regulatory framework for biotechnology is still in a state of flux.

Public perceptions of biotechnology.

PubMed

McHughen, Alan

2007-09-01

The very term 'Biotechnology' elicits a range of emotions, from wonder and awe to downright fear and hostility. This is especially true among non-scientists, particularly in respect of agricultural and food biotechnology. These emotions indicate just how poorly understood agricultural biotechnology is and the need for accurate, dispassionate information in the public sphere to allow a rational public debate on the actual, as opposed to the perceived, risks and benefits of agricultural biotechnology. This review considers first the current state of public knowledge on agricultural biotechnology, and then explores some of the popular misperceptions and logical inconsistencies in both Europe and North America. I then consider the problem of widespread scientific illiteracy, and the role of the popular media in instilling and perpetuating misperceptions. The impact of inappropriate efforts to provide 'balance' in a news story, and of belief systems and faith also impinges on public scientific illiteracy. Getting away from the abstract, we explore a more concrete example of the contrasting approach to agricultural biotechnology adoption between Europe and North America, in considering divergent approaches to enabling coexistence in farming practices. I then question who benefits from agricultural biotechnology. Is it only the big companies, or is it society at large--and the environment--also deriving some benefit? Finally, a crucial aspect in such a technologically complex issue, ordinary and intelligent non-scientifically trained consumers cannot be expected to learn the intricacies of the technology to enable a personal choice to support or reject biotechnology products. The only reasonable and pragmatic alternative is to place trust in someone to provide honest advice. But who, working in the public interest, is best suited to provide informed and accessible, but objective, advice to wary consumers?

Biotechnology risks and benefits: Science instructor perspectives and practices

NASA Astrophysics Data System (ADS)

Gardner, Grant Ean

Developing scientifically literate students who understand the socially contextualized nature of science and technology is a national focus of science education reform. Understanding teachers' views on this topic is of equal importance. This document focuses on the topic of risks and benefits posed by science and technology as an important topic for which the socially contextualized nature of science and technology readily emerges. Following introduction of a theoretical model and a review of the literature, two research studies are described that examined teachers' perceptions of the risks posed by biotechnology and the role of risk topics in an undergraduate science course. The first research study examines four groups of science educators; pre-service science teachers, in-service science teachers, science graduate teaching assistants, and science professors (n = 91). The participants completed a survey and card sort task to determine their perceptions of the risks of biotechnology. The results show that teacher perceptions were shaped by the risk severity, regulation processes, public acceptance, fear, reciprocal benefits, and whether the applications would impact humans or the environment. Factors determining risk perception included personal worldviews, trust in communicating institutions, and personal experiences with biotechnology. The different types of science teachers were compared and contrasted in light of these factors and the implications of instructor perceptions on science pedagogy are discussed. The second research manuscript describes a case study in which six biology graduate teaching assistants (GTAs) were observed teaching as lesson on the potential risks and benefits of biotechnology. The data sources included classroom observations and semi-structured interviews. Qualitative analysis reveals that GTAs framed the instruction of risk in one of three ways: analytical, focus on perspectives and biases, and promotion of individual reflection

The wide-spread prevalence of unimproved sanitation technologies has been a major cause of concern for the environment and public health, and China is no exception to this. Towards the sanitation issue, toilet revolution has become a buzzword in China recently. This paper elaborates the backgrounds, connotations, and actions of the toilet revolution in China. The toilet revolution aims to create sanitation infrastructure and public services that work for everyone and that turn waste into value. Opportunities for implementing the toilet revolution include: fulfilling Millennium Development Goals and new Sustainable Development Goals; government support at all levels for popularizing sanitary toilet; environmental protection to alleviate wastewater pollution; resource recovery from human waste and disease prevention for health and wellbeing improvement. Meanwhile, the challenges faced are: insufficient funding and policy support, regional imbalance and lagging approval processes, weak sanitary awareness and low acceptance of new toilets, lack of R&D and service system. The toilet revolution requires a concerted effort from many governmental departments. It needs to address not only technology implementation, but also social acceptance, economic affordability, maintenance issues and, increasingly, gender considerations. Aligned with the ecological sanitation principles, it calls for understanding issues across the entire sanitation service chain. Public-private partnership is also recommended to absorb private capital to make up the lack of funds, as well as arouse the enthusiasm of the public. Copyright © 2017 The Authors.

Revolutions in Neuroscience: Tool Development

PubMed Central

Bickle, John

2016-01-01

Thomas Kuhn’s famous model of the components and dynamics of scientific revolutions is still dominant to this day across science, philosophy, and history. The guiding philosophical theme of this article is that, concerning actual revolutions in neuroscience over the past 60 years, Kuhn’s account is wrong. There have been revolutions, and new ones are brewing, but they do not turn on competing paradigms, anomalies, or the like. Instead, they turn exclusively on the development of new experimental tools. I adopt a metascientific approach and examine in detail the development of two recent neuroscience revolutions: the impact of engineered genetically mutated mammals in the search for causal mechanisms of “higher” cognitive functions; and the more recent impact of optogenetics and designer receptors exclusively activated by designer drugs (DREADDs). The two key metascientific concepts, I derive from these case studies are a revolutionary new tool’s motivating problem, and its initial and second-phase hook experiments. These concepts hardly exhaust a detailed metascience of tool development experiments in neuroscience, but they get that project off to a useful start and distinguish the subsequent account of neuroscience revolutions clearly from Kuhn’s famous model. I close with a brief remark about the general importance of molecular biology for a current philosophical understanding of science, as comparable to the place physics occupied when Kuhn formulated his famous theory of scientific revolutions.

The rise (and decline?) of biotechnology.

Kinch, Michael S

2014-11-01

Since the 1970s, biotechnology has been a key innovator in drug development. An analysis of FDA-approved therapeutics demonstrates pharmaceutical companies outpace biotechs in terms of new approvals but biotechnology companies are now responsible for earlier-stage activities (patents, INDs or clinical development). The number of biotechnology organizations that contributed to an FDA approval began declining in the 2000s and is at a level not seen since the 1980s. Whereas early biotechnology companies had a decade from first approval until acquisition, the average acquisition of a biotechnology company now occurs months before their first FDA approval. The number of hybrid organizations that arise when pharmaceutical companies acquire biotechnology is likewise declining, raising questions about the sustainability of biotechnology.

This paper tries to yield an economic valuation of biotechnological activities in terms of aggregated production and employment. This valuation goes beyond direct estimation and includes the indirect effects derived from sectorial linkages between biotechnological activities and the rest of economic system. To deal with the proposed target several sources of data have been used, including official data from National Statistical Office (INE) such us national accounts, input-output tables, and innovation surveys, as well as, firms' level balance sheets and income statements and also specific information about research projects compiled by Genoma Spain Foundation. Methodological approach is based on the estimation of a new input-output table which includes the biotechnological activities as a specific branch. This table offers both the direct impact of these activities and the main parameters to obtain the induced effects over the rest of the economic system. According to the most updated available figures, biotechnological activities would have directly generated almost 1,600 millions of euros in 2005, and they would be employed more than 9,000 workers. But if we take into account the full linkages with the rest of the system, the macroeconomic impact of Biotechnological activities would reach around 5,000 millions euros in production terms (0.6% of total GDP) and would be responsible, directly or indirectly, of more than 44,000 employments.

Current state and perspectives of producing biodiesel‐like compounds by biotechnology

Uthoff, Stefan; Bröker, Daniel; Steinbüchel, Alexander

2009-01-01

Summary The global demand for crude oil is expected to continue to rise in future while simultaneously oil production is currently reaching its peak. Subsequently, rising oil prices and their negative impacts on economy, together with an increased environmental awareness of our society, directed the focus also on the biotechnological production of fuels. Although a wide variety of such fuels has been suggested, only the production of ethanol and biodiesel has reached a certain economic feasibility and volume, yet. This review focuses on the current state and perspectives of biotechnological production of biodiesel‐like compounds. At present by far most of the produced biodiesel is obtained by chemical transesterification reactions, which cannot meet the demands of a totally ‘green’ fuel production. Therefore, also several biotechnological biodiesel production processes are currently being developed. Biotechnological production can be achieved by purified enzymes in the soluble state, which requires cost‐intensive protein preparation. Alternatively, enzymes could be immobilized on an appropriate matrix, enabling a reuse of the enzyme, although the formation of by‐products may provide difficulties to maintain the enzyme activity. Processes in presence of organic solvents like t‐butanol have been developed, which enhance by‐product solubility and therefore prevent loss of enzyme activity. As another approach the application of whole‐cell catalysis for the production of fatty acid ethyl esters, which is also referred to as ‘microdiesel’, by recombinant microorganisms has recently been suggested.

The marriage of biotechnology and the pharmaceutical industry (pharma) is predicated on an evolution in technology and product innovation. It has come as a result of advances in both the science and the business practices of the biotechnology sector in the past 30 years. Biotechnology products can be thought of as "intelligent pharmaceuticals," in that they often provide novel mechanisms of action, new approaches to disease control, higher clinical success rates, improved patient care, extended patent protection, and a significant likelihood of reimbursement. Although the first biotechnology product, insulin, was approved just 32 years ago in 1982, today there are more than 200 biotechnology products commercially available. Research has expanded to include more than 900 biotechnology products in clinical trials. Pharma is substantially engaged in both the clinical development of these products and their commercialization.

The objectives were to determine the interests and attitudes of the U.S. biotechnology industry toward space biotechnology and to prepare a concise review of the current activities of the biotechnology industry. In order to accomplish these objectives, two primary actions were taken. First, a questionnaire was designed, reviewed, and distributed to U.S. biotechnology companies. Second, reviews of the various biotechnology fields were prepared in several aspects of the industry. For each review, leading figures in the field were asked to prepare a brief review pointing out key trends and current industry technical problems. The result is a readable narrative of the biotechnology industry which will provide space scientists and engineers valuable clues as to where the space environment can be explored to advance the U.S. biotechnology industry.

The Coming Primary Care Revolution.

Ellner, Andrew L; Phillips, Russell S

The United States has the most expensive, technologically advanced, and sub-specialized healthcare system in the world, yet it has worse population health status than any other high-income country. Rising healthcare costs, high rates of waste, the continued trend towards chronic non-communicable disease, and the growth of new market entrants that compete with primary care services have set the stage for fundamental change in all of healthcare, driven by a revolution in primary care. We believe that the coming primary care revolution ought to be guided by the following design principles: 1) Payment must adequately support primary care and reward value, including non-visit-based care. 2) Relationships will serve as the bedrock of value in primary care, and will increasingly be fostered by teams, improved clinical operations, and technology, with patients and non-physicians assuming an ever-increasing role in most aspects of healthcare. 3) Generalist physicians will increasingly focus on high-acuity and high-complexity presentations, and primary care teams will increasingly manage conditions that specialists managed in the past. 4) Primary care will refocus on whole-person care, and address health behaviors as well as vision, hearing, dental, and social services. Design based on these principles should lead to higher-value healthcare, but will require new approaches to workforce training.

There is a need to clarify relationships within the actinobacterial genus Micromonospora, the type genus of the family Micromonosporaceae, given its biotechnological and ecological importance. Here, draft genomes of 40 Micromonospora type strains and two non-type strains are made available through the Genomic Encyclopedia of Bacteria and Archaea project and used to generate a phylogenomic tree which showed they could be assigned to well supported phyletic lines that were not evident in corresponding trees based on single and concatenated sequences of conserved genes. DNA G+C ratios derived from genome sequences showed that corresponding data from species descriptions were imprecise. Emended descriptions include precise base composition data and approximate genome sizes of the type strains. antiSMASH analyses of the draft genomes show that micromonosporae have a previously unrealised potential to synthesize novel specialized metabolites. Close to one thousand biosynthetic gene clusters were detected, including NRPS, PKS, terpenes and siderophores clusters that were discontinuously distributed thereby opening up the prospect of prioritising gifted strains for natural product discovery. The distribution of key stress related genes provide an insight into how micromonosporae adapt to key environmental variables. Genes associated with plant interactions highlight the potential use of micromonosporae in agriculture and biotechnology.

The neosexual revolution.

PubMed

Sigusch, V

1998-08-01

The affluent societies of the Western world have witnessed a tremendous cultural and social transformation of sexuality during the 1980s and 1990s, a process I refer to as the neosexual revolution. Up to now, this recoding and reassessment of sexuality has proceeded rather slowly and quietly. Yet both its real and its symbolic effects may indeed be more consequential than those brought about in the course of the rapid, noisy sexual revolution of the 1960s and 1970s. The neosexual revolution is dismantling the old patterns of sexuality and reassembling them anew. In the process, dimensions, intimate relationships, preferences, and sexual fragments emerge, many of which had been submerged, were unnamed, or simply did not exist before. In general, sexuality has lost much of its symbolic meaning as a cultural phenomenon. Sexuality is no longer the great metaphor for pleasure and happiness, nor is it so greatly overestimated as it was during the sexual revolution. It is now widely taken for granted, much like egotism or motility. Whereas sex was once mystified in a positive sense--as ecstasy and transgression, it has now taken on a negative mystification characterized by abuse, violence, and deadly infection. While the old sexuality was based primarily upon sexual instinct, orgasm, and the heterosexual couple, neosexualities revolve predominantly around gender difference, thrills, self-gratification, and prosthetic substitution. From the vast number of interrelated processes from which neosexualities emerge, three empirically observable phenomena have been selected for discussion here: the dissociation of the sexual sphere, the dispersion of sexual fragments, and the diversification of intimate relationships. These processes go hand in hand with the commercialization and banalization of sexuality. They are looked upon as being controlled individually through the mechanisms of a fundamentally egotistical consensus morality. In conformity with the general principles at

Here we discuss the role of microbiology in petroleum biotechnologies in relation to addressing UN Sustainable Development Goal 12 (ensure sustainable consumption and production patterns), with a focus on microbially-mediated energy recovery from unconventionals (heavy oil to methane), shale gas and fracking, bioelectrochemical systems for the production of electricity from fossil fuel resources, and innovations in synthetic biology. Furthermore, using wastes to support a more sustainable approach to fossil fuel extraction processes is considered as we undertake the move towards a more circular global economy. © 2017 The Authors.

Biotechnology in Switzerland: high on the public agenda, but only moderate support.

PubMed

Bonfadelli, Heinz; Dahinden, Urs; Leonarz, Martina

2002-04-01

In Switzerland, there have been intensive public debates about biotechnology because of the specific Swiss political system of direct democracy that led, in 1992 and 1998, to two national referenda on biotechnology regulation. As a result, the Swiss population is well informed but skeptical about this technology. These findings contrast with the deficit model of public understanding of science, which predicts a positive correlation between knowledge of, and support for, a specific technology. What role did the media play in the development of public opinion? This question is discussed because of a content analysis (time series) of national newspapers. In addition, representative surveys and focus groups yield insights into the public perception of biotechnology and the influence of mass communication for opinion formation.

Was there a Darwinian Revolution? Yes, no, and maybe!

PubMed

Ruse, Michael

2014-01-01

Was there a Darwinian Revolution and was it but part of the Scientific Revolution? Before Thomas Kuhn's Structure of Scientific Revolutions in 1962, most people thought that there was a Darwinian Revolution, that it was in some sense connected to the Scientific Revolution, but that neither question nor answer was terribly interesting. Then revolutions in science became a matter of intense debate, not so much about their very existence but about their nature. Was there a switch in world-views? Did the facts change? What was the importance of social groups? And so forth. Recently however some students of the history of science have started to argue that the very questions are misconceived and that there cannot have been a Darwinian Revolution and its relationship to the Scientific Revolution is imaginary because there are no such revolutions in science! This paper takes a sympathetic look at these issues, concluding that there is still life in the revolution-in-science issue, that Kuhn's book was seminal and still has things of importance to say, but that matters are more complex and more interesting than we thought back then.

The ISS Biotechnology Facility (BTF) platform provides scientists with a unique opportunity to carry out diverse experiments in a microgravity environment for an extended period of time. Although considerable progress has been made in preserving cells on the ISS for long periods of time for later return to Earth, future biotechnology experiments would desirably monitor, process, and analyze cells in a timely way on-orbit. One aspect of our work has been directed towards developing biochemical sensors for pH, glucose, oxygen, and carbon dioxide for perfused bioreactor system developed at Johnson Space Center. Another aspect is the examination and identification of new and advanced commercial biotechnologies that may have applications to on-orbit experiments.

A study was carried out on the construction of indicators in biotechnology in Costa Rica as part of the project "SYMBIOSIS, Cooperative Program for the Construction of Indicators in Biotechnology adapted to Latin American and Caribbean countries, to motivate the application and transference of industrial technologies". The study focused on two units: researchers and research projects developed in Costa Rica, between 1998 and 2002. For researchers, information was collected about indicators related to sex, age, teaching activities, number of projects, academic degree, area of speciality and number of publications. For research projects we obtained information about: speciality, sector of application, duration of projects and number of researchers per project. Very interesting results include the high participation of the women in this area of investigation (54%); the low participation of young researchers (13% younger than 30), and a high proportion of the investigators that are responsible for 4 or more projects (42%). With relation to the specialities of the projects, the majority are in the category Bio-Agro (39%) whereas in Acuaculture only 1% was found. The sectors of application with the most number of projects are: Agriculture and Livestock (37%) and Human Health (35%). The main strengthts and limitatations for the development of biotechnology in Costa Rica are discussed.

Biotechnology is a collective term for a large number of manipulations of biological material. Fields of importance in stock-keeping include: (1) manipulation of reproductive processes; (2) genetic manipulation of macro-(farm) animals and micro-organisms and (3) manipulation of metabolism. Fitting in biotechnological findings in breeding-stock farming has repercussions in several fields such as the relationship between producers and the ancillary and processing industries, service industries, consumers and society as a whole. The use of biotechnical findings will also require further automation and adaptation of farm management. Biotechnology opens up a new area and new prospects for farm animal husbandry. These can only be regarded as positive when they take a permanent development of the entire section into account.

Biotechnology education as social and cultural production/reproduction of the biotechnology community

NASA Astrophysics Data System (ADS)

Andrée, Maria

2014-03-01

This paper is a commentary to a paper by Anne Solli, Frank Bach and Björn Åkerman on how students at a technical university learn to argue as biotechnologists. Solli and her colleagues report from an ethnographic study performed during the first semester of a 5-year program in biotechnology at a technical university in Sweden. Their study demonstrates how students begin to acquire `the right way' of approaching the controversial issue of producing and consuming genetically modified organisms. In my response I discuss the ethnographic account of this particular educational practice in terms of social and cultural production/reproduction of a biotechnology community and how the participants (students and teaching professors) deal with the dialectic of individual and collective transformation. In the perspective of the biotechnology community, the work done by the teaching professor becomes a way of ensuring the future of the biotechnology community in terms of what values and objectives are held highly in the community of practice.

Biological Nanomotors with a Revolution, Linear, or Rotation Motion Mechanism

PubMed Central

Noji, Hiroyuki; Yengo, Christopher M.; Zhao, Zhengyi; Grainge, Ian

2016-01-01

SUMMARY The ubiquitous biological nanomotors were classified into two categories in the past: linear and rotation motors. In 2013, a third type of biomotor, revolution without rotation (http://rnanano.osu.edu/movie.html), was discovered and found to be widespread among bacteria, eukaryotic viruses, and double-stranded DNA (dsDNA) bacteriophages. This review focuses on recent findings about various aspects of motors, including chirality, stoichiometry, channel size, entropy, conformational change, and energy usage rate, in a variety of well-studied motors, including FoF1 ATPase, helicases, viral dsDNA-packaging motors, bacterial chromosome translocases, myosin, kinesin, and dynein. In particular, dsDNA translocases are used to illustrate how these features relate to the motion mechanism and how nature elegantly evolved a revolution mechanism to avoid coiling and tangling during lengthy dsDNA genome transportation in cell division. Motor chirality and channel size are two factors that distinguish rotation motors from revolution motors. Rotation motors use right-handed channels to drive the right-handed dsDNA, similar to the way a nut drives the bolt with threads in same orientation; revolution motors use left-handed motor channels to revolve the right-handed dsDNA. Rotation motors use small channels (<2 nm in diameter) for the close contact of the channel wall with single-stranded DNA (ssDNA) or the 2-nm dsDNA bolt; revolution motors use larger channels (>3 nm) with room for the bolt to revolve. Binding and hydrolysis of ATP are linked to different conformational entropy changes in the motor that lead to altered affinity for the substrate and allow work to be done, for example, helicase unwinding of DNA or translocase directional movement of DNA.

Biotechnology has been used extensively in the development of vaccines for aquaculture. Modern molecular methods such as polymerase chain reaction (PCR), cloning and microarray analysis have facilitated antigen discovery, construction of novel candidate vaccines, and assessments of vaccine efficacy, mode of action, and host response. This review focuses on DNA vaccines for finfish to illustrate biotechnology applications in this field. Although DNA vaccines for fish rhabdoviruses continue to show the highest efficacy, DNA vaccines for several other viral and bacterial fish pathogens have now been proven to provide significant protection against pathogen challenge. Studies of the fish rhabdovirus DNA vaccines have elucidated factors that affect DNA vaccine efficacy as well as the nature of the fish innate and adaptive immune responses to DNA vaccines. As tools for managing aquatic animal disease emergencies, DNA vaccines have advantages in speed, flexibility, and safety, and one fish DNA vaccine has been licensed.

Our education system aims to equip young people with the knowledge, problem-solving skills and values to cope with an increasingly technological society. The aim of this study was to determine the effect of biotechnology education on adolescents’ understanding and attitudes about processes associated with biotechnology. Data were drawn from teacher and student interviews and surveys in the context of innovative Year 10 biotechnology courses conducted in three Western Australian high schools. The results indicate that after completing a biotechnology course students’ understanding increased but their attitudes remained constant with the exception of their views about human uses of gene technology. The findings of this study have ramifications for the design and implementation of biotechnology education courses in high schools.

Reprint of Design of synthetic microbial communities for biotechnological production processes.

PubMed

Jagmann, Nina; Philipp, Bodo

2014-12-20

In their natural habitats microorganisms live in multi-species communities, in which the community members exhibit complex metabolic interactions. In contrast, biotechnological production processes catalyzed by microorganisms are usually carried out with single strains in pure cultures. A number of production processes, however, may be more efficiently catalyzed by the concerted action of microbial communities. This review will give an overview of organismic interactions between microbial cells and of biotechnological applications of microbial communities. It focuses on synthetic microbial communities that consist of microorganisms that have been genetically engineered. Design principles for such synthetic communities will be exemplified based on plausible scenarios for biotechnological production processes. These design principles comprise interspecific metabolic interactions via cross-feeding, regulation by interspecific signaling processes via metabolites and autoinducing signal molecules, and spatial structuring of synthetic microbial communities. In particular, the implementation of metabolic interdependencies, of positive feedback regulation and of inducible cell aggregation and biofilm formation will be outlined. Synthetic microbial communities constitute a viable extension of the biotechnological application of metabolically engineered single strains and enlarge the scope of microbial production processes.

2012-02-20

Mineral-microbe interaction has been a key factor shaping the lithosphere of our planet since the Precambrian. Detailed investigation has been mainly focused on the role of bioweathering in biomining processes, leading to the selection of highly efficient microbial inoculants for the recovery of metals. Here we expand this scenario, presenting additional applications of bacteria and fungi in mineral dissolution, a process with novel biotechnological potential that has been poorly investigated. The ability of microorganisms to trigger soil formation and to sustain plant establishment and growth are suggested as invaluable tools to counteract the expansion of arid lands and to increase crop productivity. Furthermore, interesting exploitations of mineral weathering microbes are represented by biorestoration and bioremediation technologies, innovative and competitive solutions characterized by economical and environmental advantages. Overall, in the future the study and application of the metabolic properties of microbial communities capable of weathering can represent a driving force in the expanding sector of environmental biotechnology.

A new sexual revolution? Critical theory, pornography, and the Internet.

PubMed

Garlick, Steve

2011-08-01

The "sexual revolution" was a central element of North American culture in the 1960s. Today, sex is increasingly central to mainstream culture, in large part due to the Internet, and we might wonder whether we are living through a comparable period of sexual history. In this article, I revisit the work of Herbert Marcuse-the original theorist of the sexual revolution-to ask whether it can contribute to a critical theory of sexuality in the era of digital technology. After outlining Marcuse's theory of the role of Eros in social life, I discuss two pornographic Web sites that combine eroticism and social critique. I argue that Marcuse's work is valuable for its emphasis on the intersection of sex, technology, and capitalist economy, but that it needs to be supplemented by a focus on masculinity and the male body in Internet pornography.

Pharma Success in Product Development—Does Biotechnology Change the Paradigm in Product Development and Attrition.

PubMed

Evens, Ronald P

2016-01-01

The biotechnology segment of the overall biopharma industry has existed for only about 40–45 years, as a driver of new product development. This driving force was initiated with the FDA approval of recombinant human insulin in 1982, originating from the Genentech company. The pharma industry in the early years of 1970s and 1980s engaged with biotechnology companies only to a small extent with their in-licensing of a few recombinant molecules, led by Roche, Eli Lilly, and Johnson and Johnson. However, subsequently and dramatically over the last 25 years, biotechnology has become a primary driver of product and technology innovation and has become a cornerstone in new product development by all biopharma companies. This review demonstrates these evolutionary changes regarding approved products, product pipelines, novelty of the products, FDA approval rates, product sales, financial R&D investments in biotechnology, partnerships, mergers and acquisitions, and patent issues. We now have about 300 biotechnology products approved in USA covering 16 medical disciplines and about 250 indications, with the engagement of 25 pharma companies, along with their biotechnology company innovators and partners. The biotechnology pipeline involves over 1000 molecules in clinical trials, including over 300 molecules associated with the top 10 pharma companies. Product approval rates by the FDA for biotechnology products are over double the rate for drugs. Yes, the R&D paradigm has changed with biotechnology now as one of the major focuses for new product development with novel molecules by the whole biopharma industry.

Undergraduate Biotechnology Students' Views of Science Communication

NASA Astrophysics Data System (ADS)

Edmondston, Joanne Elisabeth; Dawson, Vaille; Schibeci, Renato

2010-12-01

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists' public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi-structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non-scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.

There is a revolution in health care occurring in our midst. The roots of this revolution are explored. The physician executive of the future will need a new set of skills because the health care system will change. This new, evolving set of skills includes being: Savvy about business; simultaneously employer- and customer-focused; and technologically driven. This manager must be a team builder rather than a lone ranger. These skills are learnable, just like piloting a plane or doing a surgery. None of us was born with the skill to practice medicine any more than we were born with business skills. While many physicians are depressed by the present health care climate, feeling a loss of power and a loss in spirit, the vision of the physician manager must carry them and the organizations they build forward through uncharted waters to a future which is every bit as exciting as our past.

White biotechnology: State of the art strategies for the development of biocatalysts for biorefining.

PubMed

Heux, S; Meynial-Salles, I; O'Donohue, M J; Dumon, C

2015-12-01

White biotechnology is a term that is now often used to describe the implementation of biotechnology in the industrial sphere. Biocatalysts (enzymes and microorganisms) are the key tools of white biotechnology, which is considered to be one of the key technological drivers for the growing bioeconomy. Biocatalysts are already present in sectors such as the chemical and agro-food industries, and are used to manufacture products as diverse as antibiotics, paper pulp, bread or advanced polymers. This review proposes an original and global overview of highly complementary fields of biotechnology at both enzyme and microorganism level. A certain number of state of the art approaches that are now being used to improve the industrial fitness of biocatalysts particularly focused on the biorefinery sector are presented. The first part deals with the technologies that underpin the development of industrial biocatalysts, notably the discovery of new enzymes and enzyme improvement using directed evolution techniques. The second part describes the toolbox available by the cell engineer to shape the metabolism of microorganisms. And finally the last part focuses on the 'omic' technologies that are vital for understanding and guide microbial engineering toward more efficient microbial biocatalysts. Altogether, these techniques and strategies will undoubtedly help to achieve the challenging task of developing consolidated bioprocessing (i.e. CBP) readily available for industrial purpose.

Biotechnology uses substances, materials or extracts derived from living cells, employing 22 million Europeans in a € 1.5 Tn endeavour, being the premier global economic growth opportunity this century. Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications. Biotechnology will deliver solutions to unimagined problems, providing food security, health and well-being to mankind for centuries to come. Copyright © 2013

However, the views on the interface between science and society held by scientists who work in the field of emerging biotechnologies are currently insufficiently explored. Therefore filling this gap is one of the urgent desiderata in the further development of a dialogue-oriented model of science-public interaction. Against this background, this article addresses two main questions: (1) How do the persons who work in the field of science perceive the public and its involvement in science? (2) What preferred modes of communication are stressed by those scientists? This research is based on a set of interviews with full professors from the field of biotechnology with a special focus on synthetic biology. The results show that scientists perceive the public as holding a primarily risk-focused view of science. On the one hand, different forms of science communication are thereby either seen as a chance to improve the public acceptance of science in general and one field of research in particular. On the other hand, the exchange with the public is seen as a duty because the whole of society is affected by scientific innovation. Yet, some of the stakeholders’ views discussed here conflict with debates on public engagement in technological innovation. PMID:26660160

The Darwinian revolution: Rethinking its meaning and significance

PubMed Central

Ruse, Michael

2009-01-01

The Darwinian revolution is generally taken to be one of the key events in the history of Western science. In recent years, however, the very notion of a scientific revolution has come under attack, and in the specific case of Charles Darwin and his Origin of Species there are serious questions about the nature of the change (if there was such) and the specifically Darwinian input. This article considers these issues by addressing these questions: Was there a Darwinian revolution? That is, was there a revolution at all? Was there a Darwinian revolution? That is, what was the specific contribution of Charles Darwin? Was there a Darwinian revolution? That is, what was the conceptual nature of what occurred on and around the publication of the Origin? I argue that there was a major change, both scientifically and in a broader metaphysical sense; that Charles Darwin was the major player in the change, although one must qualify the nature and the extent of the change, looking particularly at things in a broader historical context than just as an immediate event; and that the revolution was complex and we need the insights of rather different philosophies of scientific change to capture the whole phenomenon. In some respects, indeed, the process of analysis is still ongoing and unresolved. PMID:19528652

The costly benefits of opposing agricultural biotechnology.

PubMed

Apel, Andrew

2010-11-30

Rigorous application of a simple definition of what constitutes opposition to agricultural biotechnology readily encompasses a wide array of key players in national and international systems of food production, distribution and governance. Even though the sum of political and financial benefits of opposing agricultural biotechnology appears vastly to outweigh the benefits which accrue to providers of agricultural biotechnology, technology providers actually benefit from this opposition. If these barriers to biotechnology were removed, subsistence farmers still would not represent a lucrative market for improved seed. The sum of all interests involved ensures that subsistence farmers are systematically denied access to agricultural biotechnology. Copyright © 2010 Elsevier B.V. All rights reserved.

Needs and means for education and training in biotechnology: perspectives from developing countries and Europe.

PubMed

Grainger, J M

1996-09-01

A plenary discussion session on 'Biotechnology education and training programs' at the Xth International Conference on The global Impacts of Applied Microbiology in 1995 gave an opportunity to identify current priorities for biotechnology in developing countries. The discussion focused on three major areas: the nature of the skills required; education and training for the various categories of staff; the role of the scientific community in informing the decision makers about biotechnology and its prospects. Comparable discussions are taking place in Europe and elsewhere in the industrialized world. They are exemplified by developments arising from a White Paper on 'Growth, Competitiveness, Employment' published by the European Commission in 1993 which included a reinforcement of the work of the European Initiative for Biotechnology Education (EIBE) for teachers in schools. There are also widespread anxieties about the effects of deficiencies in the amount of attention being given to microbiology in undergraduate courses.

Avian Biotechnology.

PubMed

Nakamura, Yoshiaki

2017-01-01

Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

The application of biotechnology is a potential tool for mitigating the present and future fooding and clothing demands in developing countries like India. The commercialization of biotechnological products might benefiting the poor`s in developing countries are unlikely to be developed. Biotechnology has the potential to provide a wide range of products and the existing production skills in the industrial, pharmaceuticals and the agricultural sector. Ownership of the intellectual property rights is the key factors in determining the success of any technological invention, which was introduced in the market. It provides the means for technological progress to continue of the industry of the country. The new plans, animal varieties, new methods of treatments, new crops producing food articles as such are the inventions of biotechnology. Biotechnology is the result of the application of human intelligence and knowledge to the biological processes. Most of the tools of biotechnology have been developed, by companies, governments, research in- stitutes and universities in developed nations. These human intellectual efforts deserve protection. India is a developing country with advance biotechnology based segments of pharmaceutical and agricultural industries. The Trade Related Intellectual Property Rights (TRIPS) is not likely to have a significant impact on incentives for innovation creation in the biotechnology sectors. In the recent years, the world has seen the biotechnology sector as one of greatest investment area through the Patent Law and will giving huge profit in future. The Research and Development in the field of biotechnology should be encouraged for explor- ing new tools and improve the biological systems for interest of the common people. Priority should be given to generation, evaluation, protection and effective commercial utilization of tangible products of intellectual property in agriculture and pharmaceuticals.

Re-Framing Biotechnology Regulation.

PubMed

Peck, Alison

Biotechnology is about to spill the banks of federal regulation. New genetic engineering techniques like CRISPR-Cas9 promise revolutionary breakthroughs in medicine, agriculture, and public health—but those techniques would not be regulated under the terms of the Coordinated Framework for Regulation of Biotechnology. This revolutionary moment in biotechnology offers an opportunity to correct the flaws in the framework, which was hastily patched together at the advent of the technology. The framework has never captured all relevant technologies, has never satisfied the public that risk is being effectively managed, and has never been accessible to small companies and publicly-funded labs that increasingly are positioned to make radical, life-saving innovations. This Article offers a proposal for new legislation that would reshape biotechnology regulation to better meet these goals. Key reforms include tying regulation to risk rather than technology category; consolidating agency review; capturing distinct regulatory expertise through inter-agency consultations; creating a clearinghouse to help guide applicants and disseminate information; setting up more comprehensive monitoring of environmental effects; and providing federal leadership to fill key data gaps and address socio-economic impacts.

Harris, Rebecca C

2015-01-01

This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

Fungal genome sequencing: basic biology to biotechnology.

PubMed

Sharma, Krishna Kant

2016-08-01

The genome sequences provide a first glimpse into the genomic basis of the biological diversity of filamentous fungi and yeast. The genome sequence of the budding yeast, Saccharomyces cerevisiae, with a small genome size, unicellular growth, and rich history of genetic and molecular analyses was a milestone of early genomics in the 1990s. The subsequent completion of fission yeast, Schizosaccharomyces pombe and genetic model, Neurospora crassa initiated a revolution in the genomics of the fungal kingdom. In due course of time, a substantial number of fungal genomes have been sequenced and publicly released, representing the widest sampling of genomes from any eukaryotic kingdom. An ambitious genome-sequencing program provides a wealth of data on metabolic diversity within the fungal kingdom, thereby enhancing research into medical science, agriculture science, ecology, bioremediation, bioenergy, and the biotechnology industry. Fungal genomics have higher potential to positively affect human health, environmental health, and the planet's stored energy. With a significant increase in sequenced fungal genomes, the known diversity of genes encoding organic acids, antibiotics, enzymes, and their pathways has increased exponentially. Currently, over a hundred fungal genome sequences are publicly available; however, no inclusive review has been published. This review is an initiative to address the significance of the fungal genome-sequencing program and provides the road map for basic and applied research.

Perception of emotional climate in a revolution: Test of a multistage theory of revolution in the Tunisian context.

PubMed

Rimé, Bernard; Yzerbyt, Vincent; Mahjoub, Abdelwahab

2017-12-01

Participation in social movements and collective action depends upon people's capacity to perceive their societal context. We examined this question in the context of Arab Spring revolutions. In a classic theory of revolution highlighting the role of collective emotions, Brinton (1938) claimed that revolutions, far from chaos, proceed in an orderly sequence involving four stages: euphoria, degradation, terror, and restoration. The emotional climate (EC) as perceived by ordinary Tunisian citizens (2,699 women and 3,816 men) was measured during the 4 years of the Tunisian revolution. A quadratic pattern of perceived EC measures over time provided strong support to Brinton's model. In addition, three different analyses suggested the presence of four distinct stages in the evolution of perceived EC. Third, the socio-political developments in Tunisia during the four stages proved entirely consistent with both Brinton's theoretical model and the perceived EC indicators. Finally, social identification proved closely related to the temporal evolution of positive EC scores. In sum, data from this study not only lend support to the views put forth in an heretofore untested classic theory of revolution but also demonstrate that psychosocial measurements can validly monitor a major process of socio-political transformation. © 2017 The British Psychological Society.

Ruin and Revolution in ``Hamlet."

Usher, P. D.

1999-05-01

In the cosmic allegorical interpretation of Shakespeare's "Hamlet" (BAAS 28, 859 & 1305, 1996; Mercury 26:1, 20, 1997; RPS 18:3, 6, 1997; Giornale di Astronomia 24:3, 27, 1998), the usurper King Claudius, namesake of Ptolemy, personifies geocentricity. Textual support for this reading is found in 1.2 where Hamlet is associated with the Sun, as befits a rightful heir, while Claudius is associated with the Earth. In 3.3 Claudius fears Hamlet's antics. Rosencrantz states that the lives of many depend on the well-being of the King. He warns that if the King were to be imperiled, his subjects, those "ten thousand lesser things", would fall in a "boisterous ruin" along with "each small annexment" and "petty consequence." These 10,000 lesser lights are the naked eye stars (mv ~ 6.5) which would collapse with the demise of the pre-Diggesian firmament, along with ancient planets and their geometrical contrivances. In 5.1 Shakespeare puns on "De revolutionibus" when he refers to "fine revolution." The double meaning of "revolution" (alteration, orbital motion) was in use long before 1600. Since "revolution" is used in the context of digging, it may refer as much to the Diggesian as the Copernican Revolution. Shakespeare's prescience is revealed by his anticipation of change, as encapsulated geocentricity is transformed to stellar boundlessness, while his presence is suggested by fatherly concerns and ghost-like direction.

The New High Ground: An Analysis of Space-Based Systems in the Information Revolution'

NASA Astrophysics Data System (ADS)

Mitchell, Olivia S.

2002-09-01

The Revolution in Military Affairs (RMA) was developed in 1989 by Andrew Marshall of the Office of Net Assessment in Washington. Based on Marshal Nikolai Ogarkov's doctrine of the Military-Technical Revolution, the RMA is defined as: A major change in the nature of warfare brought about by the innovative application of new technologies which, combined with dramatic changes in military doctrine, operations, and organizational concepts, fundamentally alters the character and conduct of military operations. Though no official definition exists, these requirements of technological innovation, new doctrine and operations concepts, and organizational change were used in the analysis of the 1991 Gulf War, resulting in the conclusion of the existence of a new RMA. Known as the Information Revolution, this RMA is centered on stealth technology, precision munitions, advanced sensors and increased communications, command, control, computer and intelligence (C4I). From these advancements, doctrinal development has taken place in both joint and service centered documents. These new doctrines have introduced the operational concepts of dominant maneuver, precision engagement, focused logistics and full-dimensional protection, culminating in the new core competency of full-spectrum dominance. Organizational changes to allow for the achievement of these new concepts consists of an increased focus on inter-service connectivity for joint operations and the mutation of the traditional military hierarchy into smaller, more mobile forces deployable for rapid reactions and tailored to the specific threat.

Hydrostatic pressure is a well-known physical parameter which is now considered an important variable of life, since organisms have the ability to adapt to pressure changes, by the development of resistance against this variable. In the past decades a huge interest in high hydrostatic pressure (HHP) technology is increasingly emerging among food and biosciences researchers. Microbial specific stress responses to HHP are currently being investigated, through the evaluation of pressure effects on biomolecules, cell structure, metabolic behavior, growth and viability. The knowledge development in this field allows a better comprehension of pressure resistance mechanisms acquired at sub-lethal pressures. In addition, new applications of HHP could arise from these studies, particularly in what concerns to biotechnology. For instance, the modulation of microbial metabolic pathways, as a response to different pressure conditions, may lead to the production of novel compounds with potential biotechnological and industrial applications. Considering pressure as an extreme life condition, this review intends to present the main findings so far reported in the scientific literature, focusing on microorganisms with the ability to withstand and to grow in high pressure conditions, whether they have innated or acquired resistance, and show the potential of the application of HHP technology for microbial biotechnology. © 2013.

Revolutions in energy input and material cycling in Earth history and human history

NASA Astrophysics Data System (ADS)

Lenton, Timothy M.; Pichler, Peter-Paul; Weisz, Helga

2016-04-01

Major revolutions in energy capture have occurred in both Earth and human history, with each transition resulting in higher energy input, altered material cycles and major consequences for the internal organization of the respective systems. In Earth history, we identify the origin of anoxygenic photosynthesis, the origin of oxygenic photosynthesis, and land colonization by eukaryotic photosynthesizers as step changes in free energy input to the biosphere. In human history we focus on the Palaeolithic use of fire, the Neolithic revolution to farming, and the Industrial revolution as step changes in free energy input to human societies. In each case we try to quantify the resulting increase in energy input, and discuss the consequences for material cycling and for biological and social organization. For most of human history, energy use by humans was but a tiny fraction of the overall energy input to the biosphere, as would be expected for any heterotrophic species. However, the industrial revolution gave humans the capacity to push energy inputs towards planetary scales and by the end of the 20th century human energy use had reached a magnitude comparable to the biosphere. By distinguishing world regions and income brackets we show the unequal distribution in energy and material use among contemporary humans. Looking ahead, a prospective sustainability revolution will require scaling up new renewable and decarbonized energy technologies and the development of much more efficient material recycling systems - thus creating a more autotrophic social metabolism. Such a transition must also anticipate a level of social organization that can implement the changes in energy input and material cycling without losing the large achievements in standard of living and individual liberation associated with industrial societies.

Post-green revolution advances made in biotechnology paved the way of cultivating the high-yielding, stress and disease resistant genetically modified (GM) varieties of wheat, rice, maize cotton and several other crops. The recent rapid commercialization of the genetically modified crops in Asia, Americas and Australia indicates the potentiality of this new technology. GM crops give higher yields and are rich in nutritional values containing vitamins and minerals and can thus can help to alleviate hunger and malnutrition of the growing population in the under developed and developing countries. It could also be possible to develop more biotic and abiotic stress resistant genotypes in these crops where it was difficult to develop due to the unavailability of genes of resistance in the crossing germplasms. However, further research and investigations are needed to popularize the cultivation of these crops in different parts of the world. This review provides an insight of the impact of GM crops on contemporary agriculture across the past few decades, traces its' history across time, highlights new achievements and breakthroughs and discusses the future implication of this powerful technology in the coming few decades.

Western Australian school students' understanding of biotechnology

Are science educators providing secondary school students with the background to understand the science behind recent controversies such as the recently introduced compulsory labelling of genetically modified foods? Research from the UK suggests that many secondary school students do not understand the processes or implications of modern biotechnology. The situation in Australia is unclear. In this study, 1116 15-year-old students from eleven Western Australian schools were surveyed to determine their understanding of, and attitude towards, recent advances in modern biotechnology. The results indicate that approximately one third of students have little or no understanding of biotechnology. Many students over-estimate the use of biotechnology in our society by confusing current uses with possible future applications. The results provide a rationale for the inclusion of biotechnology, a cutting edge science, in the school science curriculum

Thomas Kuhn's description and characterization of scientific revolutions set the standard for interpreting and understanding these events, but his characterization introduced an anomaly. Newtonian science was at the pinnacle of its success immediately prior to the Second Scientific Revolution. From an evolutionary point-of-view, there were no crises to be solved just problems within the Newtonian paradigm, whereas the specific crises that initiated the revolution are evident from everyone's point-of-view after the revolution. This paradox is well recognized, but it seems not to be a problem and is just ignored as if it were not important or significant. Yet this discrepancy strikes at the very heart of physics and the overall progress of science. Historical conditions currently parallel the period immediately prior to the Second Scientific Revolution indicating that a new scientific revolution is approaching. When a comparison of the two periods is made, new characteristics of scientific revolutions are identified, the paradox is solved and evidence of a Zeroth Scientific Revolution emerges from the historical record.

Creating wealth from groundwater for dollar-a-day farmers: Where the silent revolution and the four revolutions to end rural poverty meet

NASA Astrophysics Data System (ADS)

Polak, Paul; Yoder, Robert

2006-03-01

More than 550 million of the current 1.1 billion people earning less than 1-a-day earn a living from agriculture in developing countries. A revolution in water control is needed to develop and mass-disseminate new, affordable, small-plot irrigation technologies. A revolution in agriculture is required to enable smallholders to produce high-value, marketable, labor-intensive cash crops. A revolution in markets is needed to open access to markets for the crops they produce and the inputs they need to produce them. Finally, a revolution in design, based on the ruthless pursuit of affordability, is needed to harness shallow groundwater. The experiences of suppliers of treadle pumps, low-cost drip irrigation and water storage systems were examined. The wealth these technologies generated, coupled with falling prices for small diesel pumps in countries like India and China, created a suitable environment for the rapid adoption of affordable diesel pump tubewells, which in turn created vigorous water markets and expanded access to affordable irrigation water for smallholders. The combination of smallholder-centered revolutions, along with the ‘silent revolution in groundwater’ described by Llamas and Martinez-Santos (Water Sci Technol 51(8):167-174, 2005) provide new practical options for meeting the UN Millennium Development Goals on poverty and hunger by 2015.

2014-01-01

In the last decades several new biotechnologically-based therapeutics have been developed due to progress in genetic engineering. A growing challenge facing pharmaceutical scientists is formulating these compounds into oral dosage forms with adequate bioavailability. An increasingly popular approach to formulate biotechnology-based therapeutics is the use of lipid based formulation technologies. This review highlights the importance of lipid based drug delivery systems in the formulation of oral biotechnology based therapeutics including peptides, proteins, DNA, siRNA and vaccines. The different production procedures used to achieve high encapsulation efficiencies of the bioactives are discussed, as well as the factors influencing the choice of excipient. Lipid based colloidal drug delivery systems including liposomes and solid lipid nanoparticles are reviewed with a focus on recent advances and updates. We further describe microemulsions and self-emulsifying drug delivery systems and recent findings on bioactive delivery. We conclude the review with a few examples on novel lipid based formulation technologies.

White biotechnology: ready to partner and invest in.

Kircher, Manfred

2006-01-01

It needs three factors to build an industry: market demand, product vision and capital. White biotechnology already produces high volume products such as feed additive amino acids and specialty products like enzymes for enantioselective biocatalysis. It serves large and diverse markets in the nutrition, wellness, pharmaceutical, agricultural and chemical industry. The total volume adds up to $ 50 billion worldwide. In spite of its proven track record, white biotechnology so far did not attract as much capital as red and even green biotechnology. However, the latest finance indicators confirm the continuously growing attractiveness of investment opportunities in white biotechnology. This article discusses white biotechnology's position and potential in the finance market and success factors.

The circular motion for airship-like bodies has thus far been calculated only for a prolate ellipsoid of revolution (reference 1, p.133 and reference 2). In this paper, however, the circular motion of elongated bodies of revolution more nearly resembling airships will be investigated. The results will give the effect of rotation on the pressure distribution and thus yield some information as to the stresses set up in an airship in circular flight.

Synthetic microbial ecosystems for biotechnology.

PubMed

Pandhal, Jagroop; Noirel, Josselin

2014-06-01

Most highly controlled and specific applications of microorganisms in biotechnology involve pure cultures. Maintaining single strain cultures is important for industry as contaminants can reduce productivity and lead to longer "down-times" during sterilisation. However, microbes working together provide distinct advantages over pure cultures. They can undertake more metabolically complex tasks, improve efficiency and even expand applications to open systems. By combining rapidly advancing technologies with ecological theory, the use of microbial ecosystems in biotechnology will inevitably increase. This review provides insight into the use of synthetic microbial communities in biotechnology by applying the engineering paradigm of measure, model, manipulate and manufacture, and illustrate the emerging wider potential of the synthetic ecology field. Systems to improve biofuel production using microalgae are also discussed.

Termites as targets and models for biotechnology.

PubMed

Scharf, Michael E

2015-01-07

Termites have many unique evolutionary adaptations associated with their eusocial lifestyles. Recent omics research has created a wealth of new information in numerous areas of termite biology (e.g., caste polyphenism, lignocellulose digestion, and microbial symbiosis) with wide-ranging applications in diverse biotechnological niches. Termite biotechnology falls into two categories: (a) termite-targeted biotechnology for pest management purposes, and (b) termite-modeled biotechnology for use in various industrial applications. The first category includes several candidate termiticidal modes of action such as RNA interference, digestive inhibition, pathogen enhancement, antimicrobials, endocrine disruption, and primer pheromone mimicry. In the second category, termite digestomes are deep resources for host and symbiont lignocellulases and other enzymes with applications in a variety of biomass, industrial, and processing applications. Moving forward, one of the most important approaches for accelerating advances in both termite-targeted and termite-modeled biotechnology will be to consider host and symbiont together as a single functional unit.

Cyanobacteria hold significant potential as industrial biotechnology (IB) platforms for the production of a wide variety of bio-products ranging from biofuels such as hydrogen, alcohols and isoprenoids, to high-value bioactive and recombinant proteins. Underpinning this technology, are the recent advances in cyanobacterial “omics” research, the development of improved genetic engineering tools for key species, and the emerging field of cyanobacterial synthetic biology. These approaches enabled the development of elaborate metabolic engineering programs aimed at creating designer strains tailored for different IB applications. In this review, we provide an overview of the current status of the fields of cyanobacterial omics and genetic engineering with specific focus on the current molecular tools and technologies that have been developed in the past five years. The paper concludes by giving insights on future commercial applications of cyanobacteria and highlights the challenges that need to be addressed in order to make cyanobacterial industrial biotechnology more feasible in the near future.

Biotechnological production of aromatic compounds of the extended shikimate pathway from renewable biomass.

PubMed

Lee, Jin-Ho; Wendisch, Volker F

2017-09-10

Aromatic chemicals that contain an unsaturated ring with alternating double and single bonds find numerous applications in a wide range of industries, e.g. paper and dye manufacture, as fuel additives, electrical insulation, resins, pharmaceuticals, agrochemicals, in food, feed and cosmetics. Their chemical production is based on petroleum (BTX; benzene, toluene, and xylene), but they can also be obtained from plants by extraction. Due to petroleum depletion, health compliance, or environmental issues such as global warming, the biotechnological production of aromatics from renewable biomass came more and more into focus. Lignin, a complex polymeric aromatic molecule itself, is a natural source of aromatic compounds. Many microorganisms are able to catabolize a plethora of aromatic compounds and interception of these pathways may lead to the biotechnological production of value-added aromatic compounds which will be discussed for Corynebacterium glutamicum. Biosynthesis of aromatic amino acids not only gives rise to l-tryptophan, L-tyrosine and l-phenylalanine, but also to aromatic intermediates such as dehydroshikimate or chorismate from which value-added aromatic compounds can be derived. In this review, we will summarize recent strategies for the biotechnological production of aromatic and related compounds from renewable biomass by Escherichia coli, Pseudomonas putida, C. glutamicum and Saccharomyces cerevisiae. In particular, we will focus on metabolic engineering of the extended shikimate pathway. Copyright © 2016 Elsevier B.V. All rights reserved.

Williamson, E Diane

2017-08-01

The purpose of this review is to survey current, emerging and predicted future biotechnologies which are impacting, or are likely to impact in the future on the life sciences, with a projection for the coming 20 years. This review is intended to discuss current and future technical strategies, and to explore areas of potential growth during the foreseeable future. Information technology approaches have been employed to gather and collate data. Twelve broad categories of biotechnology have been identified which are currently impacting the life sciences and will continue to do so. In some cases, technology areas are being pushed forward by the requirement to deal with contemporary questions such as the need to address the emergence of anti-microbial resistance. In other cases, the biotechnology application is made feasible by advances in allied fields in biophysics (e.g. biosensing) and biochemistry (e.g. bio-imaging). In all cases, the biotechnologies are underpinned by the rapidly advancing fields of information systems, electronic communications and the World Wide Web together with developments in computing power and the capacity to handle extensive biological data. A rationale and narrative is given for the identification of each technology as a growth area. These technologies have been categorized by major applications, and are discussed further. This review highlights: Biotechnology has far-reaching applications which impinge on every aspect of human existence. The applications of biotechnology are currently wide ranging and will become even more diverse in the future. Access to supercomputing facilities and the ability to manipulate large, complex biological datasets, will significantly enhance knowledge and biotechnological development.

Water and the other three revolutions needed to end rural poverty.

Polak, P

2005-01-01

Eight hundred million of the current 1.1 billion people who earn less than a dollar-a-day live in rural areas in developing countries. Since more than 550 million of them earn their living from agriculture, poverty eradication depends on increasing their income from farming. The millennium goals for hunger and poverty in the semi-arid tropics will not be met without four simultaneous revolutions. A revolution in water is needed to develop and mass disseminate a whole range of new affordable small plot irrigation technology. A revolution in agriculture is required to enable smallholders to produce a variety of high value marketable labor intensive cash crops. A revolution in markets is needed to open access to inputs and to profitable markets for their high value crops, incorporating effective strategies for aggregation, quality control, and decentralized added value processing. Finally, a revolution in design based on the ruthless pursuit of affordability is needed to support the other three revolutions. This paper describes the rapidly growing micro-irrigation revolution exemplified by the 250 million dollars in new net annual income now being earned by Treadle Pump farmers, and outlines the key features of the other three revolutions required to meet millennium poverty goals.

High-quality research in the field of marine biotechnology is one of the key-factors for successful innovation in exploiting the vast diversity of marine life. However, fascinating scientific research with promising results and claims on promising potential applications (e.g. for pharmaceuticals, nutritional supplements, (feed-)products for aquaculture and bioremediation solutions) is not the only factor to realise the commercial applications of marine biotechnology. What else is needed to exploit the promising potential of marine biotechnology and to create new industrial possibilities? In the study project 'Ocean Farming-Sustainable exploitation of marine organisms', we explore the possibilities of marine organisms to fulfill needs, such as safe and healthy food, industrial (raw) materials and renewable energy in a sustainable way. One of the three design groups is envisioning the future of strong land-based 'marine' market chains. Marine biotechnology is one of the foci of attention in this design group. This article provides a model of future-oriented thinking in which a variety of experts actively participate.

Improvements are needed in the characterization, safety, and quality control of food materials, in processing methods, in waste conversion and utilization processes, and in currently used food microorganism and tissue culture systems. Also needed are fundamental studies of the structure-function relationship of food materials and of the cell physiology and biochemistry of raw materials.

Hacking the quantum revolution: 1925-1975

2015-01-01

I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature - and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

Nevertheless, one could argue that there has been a revolution in detection affairs in the past several decades as the innovative application of new technology has changed the character and conduct of detection operations. This revolution will likely be most effectively reinforced in the coming decades with the networking of detectors and innovative application of anomaly detection algorithms.

Cannabinoids have shown diverse and critical effects on the body systems, which alter the physiological functions. Synthetic cannabinoids are comparatively innovative misuse drugs with respect to their nature of synthesis. Synthetic cannabinoids therapy in healthy, chain smokers, and alcoholic individuals cause damage to the immune and nervous system, eventually leading to intoxication throughout the body. Relevant studies were retrieved using major electronic databases such as PubMed, EMBASE, Medline, Scopus, and Google Scholar. The extensive use of Cannabis Sativa L. (C. Sativa) and its derivatives/analogues such as the nonpsychoactive dimethyl heptyl homolog (CBG-DMH), and tetrahydrocannabivarin (THCV) amongst juveniles and adults have been enhanced in recent years. Cannabinoids play a crucial role in the induction of respiratory, reproductive, immune and carcinogenic effects; however, potential data about mutagenic and developmental effects are still insufficient. The possible toxicity associated with the prolong use of cannabinoids acts as a tumor promoter in animal models and humans. Particular synthetic cannabinoids and analogues have low affinity for CB1 or CB2 receptors, while some synthetic members like Δ9-THC have high affinity towards these receptors. Cannabinoids and their derivatives have a direct or indirect association with acute and long-term toxicity. To reduce/attenuate cannabinoids toxicity, pharmaceutical biotechnology and cloning methods have opened a new window to develop cannabinoids encoding the gene tetrahydrocannabinolic acid (THCA) synthase. Plant revolution and regeneration hindered genetic engineering in C. Sativa. The genetic culture suspension of C. Sativa can be transmuted by the use of Agrobacterium tumefaciens to overcome its toxicity. The main aim of the present review was to collect evidence of the endo-cannabinoid system (ECS), cannabinoids toxicity, and the potential biotechnological approach of cannabinoids synthesis. PMID

Ion Emittance Growth Due to Focusing Modulation from Slipping Electron Bunch

Low energy RHIC operation has to be operated at an energy ranging from γ = 4.1 to γ = 10. The energy variation causes the change of revolution frequency. While the rf system for the circulating ion will operate at an exact harmonic of the revolution frequency (h=60 for 4.5 MHz rf and h=360 for 28 MHz rf.), the superconducting rf system for the cooling electron beam does not have a frequency tuning range that is wide enough to cover the required changes of revolution frequency. As a result, electron bunches will sit at different locations along the ion bunchmore » from turn to turn, i.e. the slipping of the electron bunch with respect to the circulating ion bunch. At cooling section, ions see a coherent focusing force due to the electrons’ space charge, which differs from turn to turn due to the slipping. We will try to estimate how this irregular focusing affects the transverse emittance of the ion bunch.« less

Biotechnology and Consumer Decision-Making.

PubMed

Sax, Joanna K

Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

Diagram depicts the importance of cell-cell communication as central to the understanding of cancer growth and progression, the focus of the NASA bioreactor demonstration system (BDS-05) investigation. Microgravity studies will allow us to unravel the signaling and communication between these cells with the host and potential development of therapies for the treatment of cancer metastasis. The NASA Bioreactor provides a low turbulence culture environment which promotes the formation of large, three-dimensional cell clusters. Due to their high level of cellular organization and specialization, samples constructed in the bioreactor more closely resemble the original tumor or tissue found in the body. The Bioreactor is rotated to provide gentle mixing of fresh and spent nutrient without inducing shear forces that would damage the cells. The work is sponsored by NASA's Office of Biological and Physical Research. The bioreactor is managed by the Biotechnology Cell Science Program at NASA's Johnson Space Center (JSC). NASA-sponsored bioreactor research has been instrumental in helping scientists to better understand normal and cancerous tissue development. In cooperation with the medical community, the bioreactor design is being used to prepare better models of human colon, prostate, breast and ovarian tumors. Cartilage, bone marrow, heart muscle, skeletal muscle, pancreatic islet cells, liver and kidney are just a few of the normal tissues being cultured in rotating bioreactors by investigators.

[The beginning of human life: ethical and legal perspectives in the context of biotechnological progress].

PubMed

Barretto, Vicente de Paulo; Lauxen, Elis Cristina Uhry

2017-07-13

Questions concerning the beginning of human life have pervaded society since antiquity. In the post-modern world, scientific and technological advances have fueled discussions on the issue, such that debates previously concentrated on abortion now also focus on biotechnological interventions. The article addresses the latter, reflecting on the extent to which human dignity can be considered a (hermeneutic) reference in establishing ethical and legal parameters for biotechnological advances in the definition of the beginning of human life. The study's method was critical hermeneutic ethics, with ethics at the center of the process of understanding and interpretation, observing the contours of facticity. No consensus was found on the beginning of human life, so it is essential to engage in dialogue with the new reality resulting from biotechnological advances in the process of defining ethical and legal principles for protecting the embryo and human nature, with human dignity as the reference.

How Personal Is the Political? Democratic Revolution and Fertility Decline

PubMed Central

Bailey, Amy Kate

2010-01-01

Existing theory has identified the capacity of political revolutions to effect change in a variety of social institutions, although relationships between revolution and many institutions remain unexplored. Using historical data from 22 European and four diaspora countries, I examine the temporal relationship between timing of revolution and onset of fertility decline. I hypothesize that specific kinds of revolutionary events affect fertility by engendering ideological changes in popular understandings of the individual’s relationship to society, and ultimately the legitimacy of couples’ authority over their reproductive capacities. Results demonstrate that popular democratic revolution – but not institutionalized democratic structures – predict the timing of the onset of fertility decline. PMID:19999826

Developing new ornamental cultivars with improved floral attributes is a major goal in floriculture. Biotechnological approach together with classical breeding methods has been used to modify floral color, appearance as well as for increasing disease resistance. Transgenic strategies possess immense potential to produce novel flower phenotypes that are not found in nature. Adoption of Genetic engineering has supported the idea of floral trait modification. Ornamental plant attributes like floral color, fragrance, disease resistance, and vase life can be improved by means of genetic manipulation. Therefore, we witness transgenic plant varieties of high aesthetic and commercial value. This review focuses on biotechnological advancements in manipulating key floral traits that contribute in development of diverse ornamental plant lines. Data clearly reveals that regulation of biosynthetic pathways related to characteristics like pigment production, flower morphology and fragrance is both possible and predictable. In spite of their great significance, small number of genetically engineered varieties of ornamental plants has been field tested. Today, novel flower colors production is regarded as chief commercial benefit obtained from transgenic plants. But certain other floral traits are much more important and have high commercial potential. Other than achievements such as novel architecture, modified flower color, etc., very few reports are available regarding successful transformation of other valuable horticultural characteristics. Our review also summarized biotechnological efforts related to enhancement of fragrance and induction of early flowering along with changes in floral anatomy and morphology. PMID:28473834

Perspectives on biotechnological applications of archaea.

PubMed

Schiraldi, Chiara; Giuliano, Mariateresa; De Rosa, Mario

2002-09-01

Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite extensive research, however, there are few existing industrial applications of either archaeal biomass or archaeal enzymes. This review summarizes current knowledge about the biotechnological uses of archaea and archaeal enzymes with special attention to potential applications that are the subject of current experimental evaluation. Topics covered include cultivation methods, recent achievements in genomics, which are of key importance for the development of new biotechnological tools, and the application of wild-type biomasses, engineered microorganisms, enzymes and specific metabolites in particular bioprocesses of industrial interest.

Energy and the English Industrial Revolution.

PubMed

Wrigley, E A

2013-03-13

Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

Exploitation of biotechnology in a large company.

Dart, E C

1989-08-31

Almost from the outset, most large companies saw the 'new biotechnology' not as a new business but as a set of very powerful techniques that, in time, would radically improve the understanding of biological systems. This new knowledge was generally seen by them as enhancing the process of invention and not as a substitute for tried and tested ways of meeting clearly identified targets. As the knowledge base grows, so the big-company response to biotechnology becomes more positive. Within ICI, biotechnology is now integrated into five bio-businesses (Pharmaceuticals, Agrochemicals, Seeds, Diagnostics and Biological Products). Within the Central Toxicology Laboratory it also contributes to the understanding of the mechanisms of toxic action of chemicals as part of assessing risk. ICI has entered two of these businesses (Seeds and Diagnostics) because it sees biotechnology making a major contribution to the profitability of each.

Europe has led many aspects of gene research and yet it has been unable to translate these discoveries into a globally dominant industrial sector. There are valid societal, political and financial reasons for its reluctance to deploy agricultural biotechnology but this reluctance might have unintended consequences. It will be hard to de-commoditize agriculture and improve farmer's lives. Research in medical biotechnology and the global environment might suffer. Europe could damage its overall economy and its global competitive standing.

Cavagna, L; Taylor, W J

2014-01-01

One of the most important therapeutic advances obtained in the field of rheumatology is the availability of the so-called bio(techno)logical drugs, which have deeply changed treatment perspectives in diseases such as rheumatoid arthritis and ankylosing spondylitis. According to the steadily increasing attention on gout, due to well-established prognostic and epidemiology implications, in the last 5 years, the same change of perspective has been observed also for this disease. In fact, several bio(techno)logical agents have been investigated both for the management of the articular gout symptoms, targeting mainly interleukin-1 β , as well as urate-lowering therapies such as recombinant uricases. Among the IL-1 β inhibitors, the majority of studies involve drugs such as anakinra, canakinumab, and rilonacept, but other compounds are under development. Moreover, other potential targets have been suggested, as, for example, the TNF alpha and IL-6, even if data obtained are less robust than those of IL-1 β inhibitors. Regarding urate-lowering therapies, the recombinant uricases pegloticase and rasburicase clearly showed their effectiveness in gout patients. Also in this case, new compounds are under development. The aim of this review is to focus on the various aspects of different bio(techno)logical drugs in gouty patients.

Sourdough-Based Biotechnologies for the Production of Gluten-Free Foods

Nionelli, Luana; Rizzello, Carlo Giuseppe

2016-01-01

Sourdough fermentation, a traditional biotechnology for making leavened baked goods, was almost completely replaced by the use of baker’s yeast and chemical leavening agents in the last century. Recently, it has been rediscovered by the scientific community, consumers, and producers, thanks to several effects on organoleptic, technological, nutritional, and functional features of cereal-based products. Acidification, proteolysis, and activation of endogenous enzymes cause several changes during sourdough fermentation, carried out by lactic acid bacteria and yeasts, which positively affect the overall quality of the baked goods. In particular, the hydrolysis of native proteins of the cereal flours may improve the functional features of baked goods. The wheat flour processed with fungal proteases and selected lactic acid bacteria was demonstrated to be safe for coeliac patients. This review article focuses on the biotechnologies that use selected sourdough lactic acid bacteria to potentially counteract the adverse reactions to gluten, and the risk of gluten contamination.

This article explores Pat Parker's poem "Movement in Black." It examines the ways in which she emblematizes intersectionality and simultaneity as forms of revolution in struggles of self and society. It begins with a theoretical and historical apparatus to contextualize Parker as an artist and activist. Then it offers a literary analysis of the poem, focusing on themes of time and space, marginalization and movement, difference and power, visibility and invisibility, and history and memory. It argues that Parker uses autobiographical writing to fuse personal and political sites of resistance.

Global demand for biotechnological products has increased steadily over the years. Thus, need for optimized processes and reduced costs appear as a key factor in the success of this market. A process tool of high importance is the direct or indirect use of enzymes to catalyze the generation of various substances. Also, obtaining aromas and pigments from natural sources has becoming priority in cosmetic and food industries in order to supply the demand from consumers to substitute synthetic compounds, especially when by-products can be used as starting material for this purpose. Species from Fusarium genera are recognized as promising sources of several enzymes for industrial application as well as biocatalysts in the production of aromas, pigments and second generation biofuels, among others. In addition, secondary metabolites from these strains can present important biological activities for medical field. In this approach, this review brings focus on the use of Fusarium sp. strains in biotechnological production of compounds of industrial interest, showing the most recent researches in this area, results obtained and the best process conditions for each case.

Public Acceptance of Plant Biotechnology and GM Crops.

PubMed

Lucht, Jan M

2015-07-30

A wide gap exists between the rapid acceptance of genetically modified (GM) crops for cultivation by farmers in many countries and in the global markets for food and feed, and the often-limited acceptance by consumers. This review contrasts the advances of practical applications of agricultural biotechnology with the divergent paths-also affecting the development of virus resistant transgenic crops-of political and regulatory frameworks for GM crops and food in different parts of the world. These have also shaped the different opinions of consumers. Important factors influencing consumer's attitudes are the perception of risks and benefits, knowledge and trust, and personal values. Recent political and societal developments show a hardening of the negative environment for agricultural biotechnology in Europe, a growing discussion-including calls for labeling of GM food-in the USA, and a careful development in China towards a possible authorization of GM rice that takes the societal discussions into account. New breeding techniques address some consumers' concerns with transgenic crops, but it is not clear yet how consumers' attitudes towards them will develop. Discussions about agriculture would be more productive, if they would focus less on technologies, but on common aims and underlying values.

Commercialization, patents and moral assessment of biotechnology products.

Hoedemaekers, R

2001-06-01

The biotechnology patent debates have revealed deep moral concerns about basic genetics research, R&D and specific biotechnological products, concerns that are seldom taken into consideration in Technology Assessment. In this paper important moral concerns are examined which appear at the various stages of development of a specific genetic product: a predictive genetic test. The purpose is to illustrate the need for a more contextual approach in technology assessment, which integrates the various forms of interaction between bio-technology and society or societal segments. Such an approach will generate greater insight in the moral issues at all stages of a product's life-cycle and this will facilitate decision-making on the 'morality' of a specific biotechnological product.

TERC’s EarthLabs project provides rigorous and engaging Earth and environmental science labs. Four existing modules illustrate sequences for learning science concepts through data analysis activities and hands-on experiments. A fifth module, developed with NSF, comprises a series of linked inquiry based activities focused on the cryosphere to help students understand concepts around change over time on multiple and embedded time scales. Teachers recruited from the NSF-OEDG-sponsored Texas Earth and Space Science (TXESS) Revolution teacher professional development program conducted a pedagogical review of the Cryosphere EarthLabs module and provided feedback on how well the materials matched high school needs in Texas and were aligned with state and national standards. Five TXESS Revolution teachers field tested the materials in their classrooms and then trained other TXESS Revolution teachers on their implementation during spring and summer 2010. Here we report on the results of PD delivery during the summer 2010 TXESS Revolution summer institute as determined by (1) a set of evaluation instruments that included a pre-post concept map activity to assess changes in workshop teachers’ understanding of the concepts presented, a pre-post test content knowledge test, and a pre-post survey of teachers’ comfort in teaching the Texas Earth and Space Science standards addressed by the module; (2) teacher reflections; and (3) focus group responses. The findings reveal that the teachers liked the module activities and felt they could use them to teach Environmental and Earth Science. They appreciated that the sequence of activities contributed to a deeper understanding and observed that the variety of methods used to present the information accommodates different learning styles. Information about the cryosphere was new to all the teachers. The content knowledge tests reveal that although teachers made appreciable gains, their understanding of cryosphere, how it changes

We obtain a classification of Riemannian manifolds of revolution and central potentials on them that have the strong Bertrand property: any nonsingular (that is, not contained in a meridian) orbit is closed. We also obtain a classification of manifolds of revolution and central potentials on them that have the 'stable' Bertrand property: every parallel is an 'almost stable' circular orbit, and any nonsingular bounded orbit is closed.

As of the mid-19th century, most infectious disease epidemics have been fought and slowed down by taking action on the environment (water, housing, waste) and education. This constitutes the 1st public health revolution paradigm. As we face the current epidemic of chronic diseases and the failure of the dominant biomedical model to stop them, a 2nd public health revolution is needed. The vision for this 2nd public health revolution requires a new paradigm built upon an eco-systemic definition of health and the recognition of the legitimacy for citizen participation based on the precautionary principle.

The presence of artificial light at night (ALAN) in environment is now known to have non negligible consequences on the night sky, the fauna, the flora and the human health. A real revolution is undergoing in the outdoor lighting industry threatens the night integrity. This revolution is driven by the advent of the cost-effective Light-Emitting Diode (LED) technology into the outdoor lighting industry. The LEDs provides many opportunities: they are long lasting, easily controlled, and generally allow a more efficient photometric design which, in term, may result in energy savings.After explaining the complex and non-linear behaviour of the propagation of the ALAN into the nocturnal environment, we will outline the potential impact of the ALAN on the human health and on the night sky, and we will introduce some dedicated indicators for its evaluation. We will focus on the role of the blue content of the ALAN in the evaluation of its impact. More specifically we will show how white LED technology, that often shows increased blue light content, compares to the traditional High Pressure Sodium technology. Finally, we will identify the possible mitigations to restrict the adverse impacts of the white LEDs in the urban and rural environment.

The wine industry in South Africa is over three centuries old and over the last decade has reemerged as a significant competitor in world wine markets. The Institute for Wine Biotechnology (IWBT) was established in partnership with the Department of Viticulture and Oenology at Stellenbosch University to foster basic fundamental research in the wine sciences leading to applications in the broader wine and grapevine industries. This review focuses on the different research programmes of the Institute (grapevine, yeast and bacteria biotechnology programmes, and chemical-analytical research), commercialisation activities (SunBio) and new initiatives to integrate the various research disciplines. An important focus of future research is the Wine Science Research Niche Area programme, which connects the different research thrusts of the IWBT and of several research partners in viticulture, oenology, food science and chemistry. This 'Functional Wine-omics' programme uses a systems biology approach to wine-related organisms. The data generated within the programme will be integrated with other data sets from viticulture, oenology, analytical chemistry and the sensory sciences through chemometrics and other statistical tools. The aim of the programme is to model aspects of the wine making process, from the vineyard to the finished product.

Biotechnology of non-Saccharomyces yeasts-the basidiomycetes.

PubMed

Johnson, Eric A

2013-09-01

Yeasts are the major producer of biotechnology products worldwide, exceeding production in capacity and economic revenues of other groups of industrial microorganisms. Yeasts have wide-ranging fundamental and industrial importance in scientific, food, medical, and agricultural disciplines (Fig. 1). Saccharomyces is the most important genus of yeast from fundamental and applied perspectives and has been expansively studied. Non-Saccharomyces yeasts (non-conventional yeasts) including members of the Ascomycetes and Basidiomycetes also have substantial current utility and potential applicability in biotechnology. In an earlier mini-review, "Biotechnology of non-Saccharomyces yeasts-the ascomycetes" (Johnson Appl Microb Biotechnol 97: 503-517, 2013), the extensive biotechnological utility and potential of ascomycetous yeasts are described. Ascomycetous yeasts are particularly important in food and ethanol formation, production of single-cell protein, feeds and fodder, heterologous production of proteins and enzymes, and as model and fundamental organisms for the delineation of genes and their function in mammalian and human metabolism and disease processes. In contrast, the roles of basidiomycetous yeasts in biotechnology have mainly been evaluated only in the past few decades and compared to the ascomycetous yeasts and currently have limited industrial utility. From a biotechnology perspective, the basidiomycetous yeasts are known mainly for the production of enzymes used in pharmaceutical and chemical synthesis, for production of certain classes of primary and secondary metabolites such as terpenoids and carotenoids, for aerobic catabolism of complex carbon sources, and for bioremediation of environmental pollutants and xenotoxicants. Notwithstanding, the basidiomycetous yeasts appear to have considerable potential in biotechnology owing to their catabolic utilities, formation of enzymes acting on recalcitrant substrates, and through the production of unique primary

Microscopic algae and cyanobacteria are excellent sources of numerous compounds, from raw biomass rich in proteins, oils, and antioxidants to valuable secondary metabolites with potential medical use. In the former Czechoslovakia, microalgal biotechnology developed rapidly in the 1960s with the main aim of providing industrial, high-yield sources of algal biomass. Unique cultivation techniques that are still in use were successfully developed and tested. Gradually, the focus changed from bulk production to more sophisticated use of microalgae, including production of bioactive compounds. Along the way, better understanding of the physiology and cell biology of productive microalgal strains was achieved. Currently, microalgae are in the focus again, mostly as possible sources of bioactive compounds and next-generation biofuels for the 21st century.

Electron shuttles in biotechnology.

PubMed

Watanabe, Kazuya; Manefield, Mike; Lee, Matthew; Kouzuma, Atsushi

2009-12-01

Electron-shuttling compounds (electron shuttles [ESs], or redox mediators) are essential components in intracellular electron transfer, while microbes also utilize self-produced and naturally present ESs for extracellular electron transfer. These compounds assist in microbial energy metabolism by facilitating electron transfer between microbes, from electron-donating substances to microbes, and/or from microbes to electron-accepting substances. Artificially supplemented ESs can create new routes of electron flow in the microbial energy metabolism, thereby opening up new possibilities for the application of microbes to biotechnology processes. Typical examples of such processes include halogenated-organics bioremediation, azo-dye decolorization, and microbial fuel cells. Herein we suggest that ESs can be applied widely to create new microbial biotechnology processes.

Politics and the life sciences: an unfinished revolution.

Johnson, Gary R

2011-01-01

Politics and the life sciences--also referred to as biopolitics--is a field of study that seeks to advance knowledge of politics and promote better policymaking through multidisciplinary analysis that draws on the life sciences. While the intellectual origins of the field may be traced at least into the 1960s, a broadly organized movement appeared only with the founding of the Association for Politics and the Life Sciences (APLS) in 1980 and the establishment of its journal, Politics and the Life Sciences ( PLS ), in 1982. This essay--contributed by a past journal editor and association executive director--concludes a celebration of the association's thirtieth anniversary. It reviews the founding of the field and the association, as well as the contributions of the founders. It also discusses the nature of the empirical work that will advance the field, makes recommendations regarding the identity and future of the association, and assesses the status of the revolution of which the association is a part. It argues that there is progress to celebrate, but that this revolution--the last of three great scientific revolutions--is still in its early stages. The revolution is well-started, but remains unfinished.

Bereznoy, A V; Saygitov, R T

Digital revolution is one of the major global trends resulting in the unprecedented scale and depth of penetration of information and communication technologies into all sectors of national economy, including healthcare. The development of this trend brought about high expectations related to the improvement of quality of medical assistance, accessibility and economic efficiency of healthcare services. However, euphoria of the first steps of digital revolution is passing now, opening doors to more realistic analysis of opportunities and conditions of realization of the true potential hidden in the digital transformation of healthcare. More balanced perception of the peculiarities of innovation processes in the sector is coming together with understanding of the serious barriers, hampering implementation of the new ideas and practices due to complicated interweaving of social, economic, ethical and psychological factors. When taking into account the industry specifics it becomes evident that digital revolution cannot be a quick turnaround but rather would pass a number of phases and is likely to last more than one decade. In this context the article focuses on the prospects of the new business models, capable of making significant changes in today’s economic landscape of the sector (including uber-medicine, retail clinics, retainer medicine, network models of medical services). The authors also provide assessment of the current situation and perspectives of digital healthcare development in Russia.

Guo, Ji-Wei

2009-01-01

Biotechnology has an increasingly extensive use for military purposes. With the upcoming age of biotechnology, military operations are depending more on biotechnical methods. Judging from the evolving law of the theory of command, the command of biotechnology is feasible and inevitable. The report discusses some basic characteristics of modern theories of command, as well as the mature possibility of the command theory of military biotechnology. The evolution of the command theory is closely associated with the development of military medicine. This theory is expected to achieve successes in wars in an ultramicro, nonlethal, reversible, and merciful way and will play an important role in biotechnological identification and orientation, defense and attack, and the maintenance of fighting powers and biological monitoring. The command of military biotechnology has not become a part of the virtual military power yet, but it is an exigent strategic task to construct and perfect this theory.

The Nineteenth-Century Revolution in Astronomy

NASA Astrophysics Data System (ADS)

Batten, Alan Henry

2015-08-01

The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

Kirigia, J M; Muthuri, L K; Kirigia, D G

2007-01-01

The aim of this paper is to stimulate debate on the agency (principal-agent) in health-related biotechnology research. It attempts to answer the following questions: What is health-related biotechnology and biotechnology research? What is an agency? What factors are likely to undermine the principal's capacity to exercise informed consent? When might the principal-agency problem arise? How could the agency in biotechnology transfer be strengthened in Sub-Saharan Africa (SSA)? The transfer of health-related biotechnology to SSA ought to be preceded by research to ascertain the effectiveness of such technologies on population health. In that process, the national ethical review committee (REC), as an agent of every human research subject (principal), ought to ensure that international principles (e.g. beneficence, non-malfeasance, autonomy, justice, dignity, truthfulness and honesty) for human experimentation are observed by biotechnology researchers in order to satisfy moral, ethical and legal requirements. The key factors that undermine principals' sovereignty in exercising their right to informed consent to participate in biotechnology trials are discussed. The paper ends with a list of activities that can strengthen the agency, e.g. legislative requirement that all health-related biotechnology transfer should be preceded by rigorous evaluation; continuous update of the agents knowledge of the contents of the international ethical guidelines; and education of potential and actual principals on their human rights; among others.

[Health risks in the biotechnological industry].

PubMed

Colombi, A; Maroni, M; Foà, V

1989-01-01

Biotechnology has been defined as the application of biological organisms, systems or processes to manufacturing and service industries. In considering health aspects of biotechnological development it must be underlined that the use of microorganisms in traditional industries, such as the production of food, bread, beer and dairy products, has not added significantly to the more usual industrial hazards. The risk factors encountered in the biotechnology industry can be defined as general, i.e., common to other industrial activities, and specific, i.e., depending on the presence of microorganisms and/or their metabolic products. The specific health risks vary according to the type of process, but can be grouped into three main categories: immunological diseases, toxic effects; pathological effects of microorganisms. Allergic immunological diseases such as bronchial asthma, contact dermatitis, oculo-rhinitis and extrinsic allergic alveolitis are by far the most frequent and well known diseases occurring among workers employed on biotechnological production. Toxic effects were observed among workers employed on the production of antibiotics and hormones or single cell proteins, where absorption of endotoxins has been described. Infectious diseases may arise from uncontrolled dissemination of pathogenic microorganisms through aerosols, dusts, aqueous and semisolid sludge effluents from biotechnological plants. The greatest risks occur in the production of antiviral vaccines, in research laboratories and in waste-water treatment plants. Risk of pathogenic effects has also been speculated from exposure to engineered microorganisms in laboratory and environmental or agricultural applications. Safety precautions consisting of protective measures, and effective barriers of containment (both physical and biological) have to be advised according to the hazardous characteristics of the organisms.(ABSTRACT TRUNCATED AT 250 WORDS)

Fueling industrial biotechnology growth with bioethanol.

PubMed

Otero, José Manuel; Panagiotou, Gianni; Olsson, Lisbeth

2007-01-01

Industrial biotechnology is the conversion of biomass via biocatalysis, microbial fermentation, or cell culture to produce chemicals, materials, and/or energy. Industrial biotechnology processes aim to be cost-competitive, environmentally favorable, and self-sustaining compared to their petrochemical equivalents. Common to all processes for the production of energy, commodity, added value, or fine chemicals is that raw materials comprise the most significant cost fraction, particularly as operating efficiencies increase through practice and improving technologies. Today, crude petroleum represents the dominant raw material for the energy and chemical sectors worldwide. Within the last 5 years petroleum prices, stability, and supply have increased, decreased, and been threatened, respectively, driving a renewed interest across academic, government, and corporate centers to utilize biomass as an alternative raw material. Specifically, bio-based ethanol as an alternative biofuel has emerged as the single largest biotechnology commodity, with close to 46 billion L produced worldwide in 2005. Bioethanol is a leading example of how systems biology tools have significantly enhanced metabolic engineering, inverse metabolic engineering, and protein and enzyme engineering strategies. This enhancement stems from method development for measurement, analysis, and data integration of functional genomics, including the transcriptome, proteome, metabolome, and fluxome. This review will show that future industrial biotechnology process development will benefit tremendously from the precedent set by bioethanol - that enabling technologies (e.g., systems biology tools) coupled with favorable economic and socio-political driving forces do yield profitable, sustainable, and environmentally responsible processes. Biofuel will continue to be the keystone of any industrial biotechnology-based economy whereby biorefineries leverage common raw materials and unit operations to integrate

The discovery of novel plant resistance (R) genes (including their homologs and analogs) opened interesting possibilities for controlling plant diseases caused by several pathogens. However, due to environmental pressure and high selection operated by pathogens, several crop plants have lost specificity, broad-spectrum or durability of resistance. On the other hand, the advances in plant genome sequencing and biotechnological approaches, combined with the increasing knowledge on Rgenes have provided new insights on their applications for plant genetic breeding, allowing the identification and implementation of novel and efficient strategies that enhance or optimize their use for efficiently controlling plant diseases. The present review focuses on main perspectives of application of R-genes and its co-players for the acquisition of resistance to pathogens in cultivated plants, with emphasis on biotechnological inferences, including transgenesis, cisgenesis, directed mutagenesis and gene editing, with examples of success and challenges to be faced.

Filamentous fungal secretomes comprise highly dynamic sets of proteins, including multiple carbohydrate active enzymes (CAZymes) which are able to hydrolyze plant biomass polysaccharides into products of biotechnological interest such as fermentable sugars. In recent years, proteomics has been used to identify and quantify enzymatic and non-enzymatic polypeptides present in secretomes of several fungi species. The resulting data have widened the scientific understanding of the way filamentous fungi perform biomass degradation and offered novel perspectives for biotechnological applications. The present review discusses proteomics approaches that have been applied to the study of fungal secretomes, focusing on two of the most studied filamentous fungi genera: Trichoderma and Aspergillus.

Wide adaptation of Green Revolution wheat: international roots and the Indian context of a new plant breeding ideal, 1960-1970.

PubMed

Baranski, Marci R

2015-04-01

Indian wheat cultivation changed radically in the 1960s due to new technologies and policy reforms introduced during the Green Revolution, and farmers' adoption of 'packages' of modern seeds, fertilizer, and irrigation. Just prior to the Green Revolution, Indian scientists adopted a new plant breeding philosophy--that varieties should have as wide an adaptation as possible, meaning high and stable yields across different environments. But scientists also argued that wide adaptation could be achieved by selecting only plants that did well in high fertility and irrigated environments. Scientists claimed that widely adapted varieties still produce high yields in marginal areas. Many people have criticized the Green Revolution for its unequal spread of benefits, but none of these critiques address wide adaptation-the core tenant held by Indian agricultural scientists to justify their focus on highly productive land while ignoring marginal or rainfed agriculture. This paper also describes Norman Borlaug's and the Rockefeller Foundation's research program in wide adaptation, Borlaug's involvement in the Indian wheat program, and internal debates about wide adaptation and selection under ideal conditions among Indian scientists. It argues that scientists leveraged the concept of wide adaptation to justify a particular regime of research focused on high production agriculture. Copyright © 2015 Elsevier Ltd.

Background The benefits of genomics and biotechnology are concentrated primarily in the industrialized world, while their potential to combat neglected diseases in the developing world has been largely untapped. Without building developing world biotechnology capacity to address local health needs, this disparity will only intensify. To assess the potential of genomics to address health needs in the developing world, the McLaughlin-Rotman Centre for Global Health, along with local partners, organized five courses on Genomics and Public Health Policy in the developing world. The overall objective of the courses was to collectively explore how to best harness genomics to improve health in each region. This article presents and analyzes the recommendations from all five courses. Discussion In this paper we analyze recommendations from 232 developing world experts from 58 countries who sought to answer how best to harness biotechnology to improve health in their regions. We divide their recommendations into four categories: science; finance; ethics, society and culture; and politics.

2009-01-01

Background Reproductive technologies have been extensively debated in the literature. As well, feminist economists, environmentalists, and agriculturalists have generated substantial debate and literature on gender. However, the implications for women of health biotechnologies have received relatively less attention. Surprisingly, while gender based frameworks have been proposed in the context of public health policy, practice, health research, and epidemiological research, we could identify no systematic framework for gender analysis of health biotechnology in the developing world. Discussion We propose sex and gender considerations at five critical stages of health biotechnology research and development: priority setting; technology design; clinical trials; commercialization, and health services delivery. Summary Applying a systematic sex and gender framework to five key process stages of health biotechnology research and development could be a first step towards unlocking the opportunities of this promising science for women in the developing world.

2011-12-20

This review is based on a study commissioned by the European Commission on the evaluation of scientific, technical and institutional challenges, priorities and bottlenecks for biotechnologies and regional harmonisation of biosafety in Africa. Biotechnology was considered within four domains: agricultural biotechnologies ('Green'), industrial biotechnologies and biotechnologies for environmental remediation ('White'), biotechnologies in aquaculture ('Blue') and biotechnologies for healthcare ('Red'). An important consideration was the decline in partnerships between the EU and developing countries because of the original public antipathy to some green biotechnologies, particularly genetically modified organisms (GMOs) and food from GM crops in Europe. The study focus reported here was West Africa (Ghana, Senegal, Mali and Burkina Faso). The overall conclusion was that whereas high-quality research was proceeding in the countries visited, funding is not sustained and there is little evidence of practical application of biotechnology and benefit to farmers and the wider community. Research and development that was being carried out on genetically modified crop varieties was concentrating on improving food security and therefore unlikely to have significant impact on EU markets and consumers. However, there is much non-controversial green biotechnology such as molecular diagnostics for plant and animal disease and marker-assisted selection for breeding that has great potential application. Regarding white biotechnology, it is currently occupying only a very small industrial niche in West Africa, basically in the sole sector of the production of liquid biofuels (i.e., bio-ethanol) from indigenous and locally planted biomass (very often non-food crops). The presence of diffused small-scale fish production is the basis to develop and apply new (Blue) aquaculture technologies and, where the research conditions and the production sector can permit, to increase this type of

Biotechnological Aspects of Microbial Extracellular Electron Transfer

Kato, Souichiro

2015-01-01

Extracellular electron transfer (EET) is a type of microbial respiration that enables electron transfer between microbial cells and extracellular solid materials, including naturally-occurring metal compounds and artificial electrodes. Microorganisms harboring EET abilities have received considerable attention for their various biotechnological applications, in addition to their contribution to global energy and material cycles. In this review, current knowledge on microbial EET and its application to diverse biotechnologies, including the bioremediation of toxic metals, recovery of useful metals, biocorrosion, and microbial electrochemical systems (microbial fuel cells and microbial electrosynthesis), were introduced. Two potential biotechnologies based on microbial EET, namely the electrochemical control of microbial metabolism and electrochemical stimulation of microbial symbiotic reactions (electric syntrophy), were also discussed.

Animal biotechnology is a broad field including polarities of fundamental and applied research, as well as DNA science, covering key topics of DNA studies and its recent applications. In Introduction to Pharmaceutical Biotechnology, DNA isolation procedures followed by molecular markers and screening methods of the genomic library are explained. Interesting areas like isolation, sequencing and synthesis of genes, with the broader coverage on synthesis of genes, are also described. The book begins with an introduction to biotechnology and its main branches, explaining both the basic science and the applications of biotechnology-derived pharmaceuticals, with special emphasis on their clinical use. It then moves on to historical development and scope of biotechnology with an overall review of early applications that scientists employed long before the field was defined.

Opportunities for biotechnology and policy regarding mycotoxin issues in international trade.

Kendra, David F; Dyer, Rex B

2007-10-20

Despite being introduced more than a decade ago, agricultural biotechnology still remains framed in controversy impacting both the global economy and international regulations. Controversies surrounding agricultural biotechnology produced crops and foods commonly focus on human and environmental safety, intellectual property rights, consumer choice, ethics, food security, poverty reduction and environmental conservation. Originally, some consumers were reluctant to accept the first generation agricultural biotechnology products because they appeared to primarily benefit agricultural producers; however, it is clear from continued evaluations that these technologies also improved both the safety and wholesomeness of food and helped improve the environment. Plants engineered to resist insect pests and tolerate less toxic pesticides resulted in improved yields thereby enabling farmers to produce more food per acre while reducing the need for herbicides, pesticides, and water and tilling. An indirect benefit of reduced pest damage in transgenic corn expressing genes to control insect pests is lower levels of mycotoxins, most notably those caused by the genus Fusarium. Mycotoxins are an important regulatory issue globally because of their toxic and carcinogenic potential to humans and animals. Complicating this issue is the fact that toxicological databases for mycotoxins are relatively incomplete compared to other food contaminants. Current debates about agricultural biotechnology and mycotoxins reveal significant differences in perception of associated risks and benefits. When faced with uncertainty, regulators tend to set limits as low as possible. Additionally, some regulators invoke the "Precautionary Principle" when limited information is available or disputes over interpretation exist for possible contaminants, including mycotoxins. A major concern regarding use of the "Precautionary Principle" is the appearance that regulators can justify setting any limit on the

Design of virus-based nanomaterials for medicine, biotechnology, and energy

Wen, Amy M.; Steinmetz, Nicole F.

2016-01-01

Virus-based nanomaterials are versatile materials that naturally self-assemble and have relevance for a broad range of applications including medicine, biotechnology, and energy. This review provides an overview of recent developments in “chemical virology.” Viruses, as materials, provide unique nanoscale scaffolds that have relevance in chemical biology and nanotechnology, with diverse areas of applications. Some fundamental advantages of viruses, compared to synthetically programmed materials, include the highly precise spatial arrangement of their subunits into a diverse array of shapes and sizes and many available avenues for easy and reproducible modification. Here, we will first survey the broad distribution of viruses and various methods for producing virus-based nanoparticles, as well as engineering principles used to impart new functionalities. We will then examine the broad range of applications and implications of virus-based materials, focusing on the medical, biotechnology, and energy sectors. We anticipate that this field will continue to evolve and grow, with exciting new possibilities stemming from advancements in the rational design of virus-based nanomaterials. PMID:27152673

Public Acceptance of Plant Biotechnology and GM Crops

Lucht, Jan M.

2015-01-01

A wide gap exists between the rapid acceptance of genetically modified (GM) crops for cultivation by farmers in many countries and in the global markets for food and feed, and the often-limited acceptance by consumers. This review contrasts the advances of practical applications of agricultural biotechnology with the divergent paths—also affecting the development of virus resistant transgenic crops—of political and regulatory frameworks for GM crops and food in different parts of the world. These have also shaped the different opinions of consumers. Important factors influencing consumer’s attitudes are the perception of risks and benefits, knowledge and trust, and personal values. Recent political and societal developments show a hardening of the negative environment for agricultural biotechnology in Europe, a growing discussion—including calls for labeling of GM food—in the USA, and a careful development in China towards a possible authorization of GM rice that takes the societal discussions into account. New breeding techniques address some consumers’ concerns with transgenic crops, but it is not clear yet how consumers’ attitudes towards them will develop. Discussions about agriculture would be more productive, if they would focus less on technologies, but on common aims and underlying values. PMID:26264020

Development of transgenic crops based on photo-biotechnology.

2017-11-01

The phenotypes associated with plant photomorphogenesis such as the suppressed shade avoidance response and de-etiolation offer the potential for significant enhancement of crop yields. Of many light signal transducers and transcription factors involved in the photomorphogenic responses of plants, this review focuses on the transgenic overexpression of the photoreceptor genes at the uppermost stream of the signalling events, particularly phytochromes, crytochromes and phototropins as the transgenes for the genetic engineering of crops with improved harvest yields. In promoting the harvest yields of crops, the photoreceptors mediate the light regulation of photosynthetically important genes, and the improved yields often come with the tolerance to abiotic stresses such as drought, salinity and heavy metal ions. As a genetic engineering approach, the term photo-biotechnology has been coined to convey the idea that the greater the photosynthetic efficiency that crop plants can be engineered to possess, the stronger the resistance to biotic and abiotic stresses. Development of GM crops based on photoreceptor transgenes (mainly phytochromes, crytochromes and phototropins) is reviewed with the proposal of photo-biotechnology that the photoreceptors mediate the light regulation of photosynthetically important genes, and the improved yields often come with the added benefits of crops' tolerance to environmental stresses. © 2016 John Wiley & Sons Ltd.

Strategies for biotechnology must take account of opportunities for research, innovation and business growth. At a regional level, public-private collaborations provide potential for such growth and the creation of centres of excellence. By considering recent progress in areas such as genomics, healthcare diagnostics, synthetic biology, gene editing and bio-digital technologies, opportunities for smart, strategic and specialised investment are discussed. These opportunities often involve convergent or disruptive technologies, combining for example elements of pharma-science, molecular biology, bioinformatics and novel device development to enhance biotechnology and the life sciences. Analytical applications use novel devices in mobile health, predictive diagnostics and stratified medicine. Synthetic biology provides opportunities for new product development and increased efficiency for existing processes. Successful centres of excellence should promote public-private business partnerships, clustering and global collaborations based on excellence, smart strategies and innovation if they are to remain sustainable in the longer term.

The structure of the cognitive revolution: An examination from the philosophy of science

O'Donohue, William; Ferguson, Kyle E.; Naugle, Amy E.

2003-01-01

The received view is that psychology has undergone several scientific revolutions similar to those that occurred in the physical sciences. Of these, this paper will consider the cognitive revolution. Because the arguments in favor of the existence of a cognitive revolution are cast using the concepts and terms of revolutionary science, we will examine the cognitive revolution using accounts of revolutionary science advanced by five influential philosophers of science. Specifically, we will draw from the philosophical positions of Popper, Kuhn, Lakatos, Laudan, and Gross for the purpose of discussion. We conclude that no substantive revolution took place according to these accounts. This conclusion is based on data gathered from some of the major participants in the “cognitive revolution” and on a general scholarly survey of the literature. We argue that the so-called cognitive revolution is best characterized as a socio-rhetorical phenomenon. PMID:22478396

The microgravity environment can be used to study fundamental principles of cell biology and to achieve specific applications such as tissue engineering. The Biotechnology Facility (BTF) will provide a state-of-the-art facility to perform cellular biotechnology research onboard the International Space Station (ISS). The BTF will support continuous operation, which will allow performance of long-duration experiments and will significantly increase the on-orbit science throughput. With the BTF, dedicated ground support, and a community of investigators, the goals of the Cellular Biotechnology Program at Johnson Space Center are to: Support approximately 400 typical investigator experiments during the nominal design life of BTF (10 years). Support a steady increase in investigations per year, starting with stationary bioreactor experiments and adding rotating bioreactor experiments at a later date. Support at least 80% of all new cellular biotechnology investigations selected through the NASA Research Announcement (NRA) process. Modular components - to allow sequential and continuous experiment operations without cross-contamination Increased cold storage capability (+4 C, -80 C, -180 C). Storage of frozen cell culture inoculum - to allow sequential investigations. Storage of post-experiment samples - for return of high quality samples. Increased number of cell cultures per investigation, with replicates - to provide sufficient number of samples for data analysis and publication of results in peer-reviewed scientific journals.

Ethical limitations in patenting biotechnological inventions.

PubMed

Lugagnani, V

1999-01-01

In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

In the last few years, there has been an intense interest in using microalgal lipids in food, chemical and pharmaceutical industries and cosmetology, while a noteworthy research has been performed focusing on all aspects of microalgal lipid production. This includes basic research on the pathways of solar energy conversion and on lipid biosynthesis and catabolism, and applied research dealing with the various biological and technical bottlenecks of the lipid production process. In here, we review the current knowledge in microalgal lipids with respect to their metabolism and various biotechnological applications, and we discuss potential future perspectives. The committing step in fatty acid biosynthesis is the carboxylation of acetyl-CoA to form malonyl-CoA that is then introduced in the fatty acid synthesis cycle leading to the formation of palmitic and stearic acids. Oleic acid may also be synthesized after stearic acid desaturation while further conversions of the fatty acids (i.e. desaturations, elongations) occur after their esterification with structural lipids of both plastids and the endoplasmic reticulum. The aliphatic chains are also used as building blocks for structuring storage acylglycerols via the Kennedy pathway. Current research, aiming to enhance lipogenesis in the microalgal cell, is focusing on over-expressing key-enzymes involved in the earlier steps of the pathway of fatty acid synthesis. A complementary plan would be the repression of lipid catabolism by down-regulating acylglycerol hydrolysis and/or β-oxidation. The tendency of oleaginous microalgae to synthesize, apart from lipids, significant amounts of other energy-rich compounds such as sugars, in processes competitive to lipogenesis, deserves attention since the lipid yield may be considerably increased by blocking competitive metabolic pathways. The majority of microalgal production occurs in outdoor cultivation and for this reason biotechnological applications face some difficulties

This dialogue was held between the Guest Editors of the Special Issue on "Plant Transgenesis" of the Int. J. Dev. Biol. and Marc Van Montagu. Research in the group of Marc Van Montagu and Jeff Schell in the 1970s was essential to reveal how the phytopathogenic bacterium Agrobacterium tumefaciens transfers DNA to host plants to cause crown gall disease. Knowledge of the molecular mechanism underlying gene transfer, subsequently led to the development of plant transgene technology, an indispensable tool in fundamental plant research and plant improvement. In the early 1980s, Marc Van Montagu founded a start-up company, Plant Genetic Systems, which successfully developed insect-resistant plants, herbicide-tolerant plants and a hybrid seed production system based on nuclear male sterility. Even before the first transgenic plant had been produced, Marc Van Montagu realized that the less developed countries might benefit most from plant biotechnology and throughout his subsequent career, this remained a focus of his efforts. After becoming emeritus professor, he founded the Institute of Plant Biotechnology Outreach (IPBO), which aims to raise awareness of the major role that plant biotechnology can play in sustainable agricultural systems, especially in less developed countries. Marc Van Montagu has been honored with many prizes and awards, the most recent being the prestigious World Food Prize 2013. In this paper, we look to the past and present of plant biotechnology and to the promises this technology holds for the future, on the basis of the personal perspective of Marc Van Montagu.

From satellite altimetry to Argo and operational oceanography: three revolutions in oceanography

The launch of the French/US mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large-scale sea level and ocean circulation observations was flying. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. Together with my CLS colleagues, we demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. Near-real-time high-resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 yr. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. Altimetry needs to be complemented with global in situ observations. At the end of the 90s, a major international initiative was launched to develop Argo, the global array of profiling floats. This has been an outstanding success. Argo floats now provide the most important in situ observations to monitor and understand the role of the ocean on the earth climate and for operational oceanography. This is a second revolution in oceanography. The unique capability of satellite altimetry to observe the global ocean in near-real-time at high resolution and the development of Argo were essential for the development of global operational oceanography, the third revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) was instrumental in the development of the required capabilities. This paper provides an historical perspective on the development of these three revolutions in oceanography which are very much interlinked.

Concerns about food allergy and its societal growth are intertwined with the growing advances in plant biotechnology. The knowledge of plant genes and protein structures provides the key foundation to understanding biochemical processes that produce food allergy. Biotechnology offers the prospect of producing low-allergen or allergen null plants that could mitigate the allergic response. Modified low-IgE binding variants of allergens could be used as a vaccine to build immunotolerance in sensitive individuals. The potential to introduce new allergens into the food supply by biotechnology products is a regulatory concern. Copyright © 2010 Elsevier Ltd. All rights reserved.

Pathogenic bacteria have evolved sophisticated strategies to overcome host defences, to interact with the immune system and to interfere with essential host systems. We coin the term 'patho-biotechnology' to describe the exploitation of these valuable traits in biotechnology, medicine and food. This approach shows promise for the development of novel vaccine and drug delivery systems, as well as for the design of more technologically robust and effective probiotic cultures with improved biotechnological and clinical applications. The genetic tractability of Listeria monocytogenes, the availability of the complete genome sequence of this intracellular pathogen, its ability to cope with stress, and its ability to traverse the gastrointestinal tract and induce a strong cellular immune response make L. monocytogenes an ideal model organism for demonstrating the patho-biotechnology concept.

Supermarket revolution in Asia and emerging development strategies to include small farmers.

PubMed

Reardon, Thomas; Timmer, C Peter; Minten, Bart

2012-07-31

A "supermarket revolution" has occurred in developing countries in the past 2 decades. We focus on three specific issues that reflect the impact of this revolution, particularly in Asia: continuity in transformation, innovation in transformation, and unique development strategies. First, the record shows that the rapid growth observed in the early 2000s in China, Indonesia, Malaysia, and Thailand has continued, and the "newcomers"--India and Vietnam--have grown even faster. Although foreign direct investment has been important, the roles of domestic conglomerates and even state investment have been significant and unique. Second, Asia's supermarket revolution has exhibited unique pathways of retail diffusion and procurement system change. There has been "precocious" penetration of rural towns by rural supermarkets and rural business hubs, emergence of penetration of fresh produce retail that took much longer to initiate in other regions, and emergence of Asian retail developing-country multinational chains. In procurement, a symbiosis between modern retail and the emerging and consolidating modern food processing and logistics sectors has arisen. Third, several approaches are being tried to link small farmers to supermarkets. Some are unique to Asia, for example assembling into a "hub" or "platform" or "park" the various companies and services that link farmers to modern markets. Other approaches relatively new to Asia are found elsewhere, especially in Latin America, including "bringing modern markets to farmers" by establishing collection centers and multipronged collection cum service provision arrangements, and forming market cooperatives and farmer companies to help small farmers access supermarkets.

The biology of planktotrophic larvae of Concholepas concholepas is the main bottleneck towards developing biotechnologies to rear this muricid. Data concerning planktonic larvae development, diets and environmental signals triggering larval settlement and recruitment is scarce. We have begun the study of the molecular and cell biology of embryos, larvae and recruits having as a final goal, the development of appropriate biotechnologies to rear this gastropod. First, an inverse ratio between BuChE and AChE enzyme activities was established. This ratio may be a precise developmental marker for this species. Second, for the first time a phosphoinositide related regulatory pathway is reported in a muricid, opening a new approach to the biotechnological management of larvae. Third, the relation between sulfate in sea water and larval motility was studied. Concentrations below 125 microM sulfate decreases larval motility. The sulfate is incorporated in proteoglycans which participate in different developmental phenomena. Lastly, a genomic Concholepas concholepas DNA sequence, similar to that of a human growth hormone probe was detected. This is very interesting since growth factors are key molecules during development, growth and are involved in food conversion rates in fish and also, in a variety of marine invertebrates.

Organisation of biotechnological information into knowledge.

Boh, B

1996-09-01

The success of biotechnological research, development and marketing depends to a large extent on the international transfer of information and on the ability to organise biotechnology information into knowledge. To increase the efficiency of information-based approaches, an information strategy has been developed and consists of the following stages: definition of the problem, its structure and sub-problems; acquisition of data by targeted processing of computer-supported bibliographic, numeric, textual and graphic databases; analysis of data and building of specialized in-house information systems; information processing for structuring data into systems, recognition of trends and patterns of knowledge, particularly by information synthesis using the concept of information density; design of research hypotheses; testing hypotheses in the laboratory and/or pilot plant; repeated evaluation and optimization of hypotheses by information methods and testing them by further laboratory work. The information approaches are illustrated by examples from the university-industry joint projects in biotechnology, biochemistry and agriculture.

Applications of Protein Hydrolysates in Biotechnology

NASA Astrophysics Data System (ADS)

Pasupuleti, Vijai K.; Holmes, Chris; Demain, Arnold L.

By definition, protein hydrolysates are the products that are obtained after the hydrolysis of proteins and this can be achieved by enzymes, acid or alkali. This broad definition encompasses all the products of protein hydrolysis - peptides, amino acids and minerals present in the protein and acid/alkali used to adjust pH (Pasupuleti 2006). Protein hydrolysates contain variable side chains depending on the enzymes used. These side chains could be carboxyl, amino, imidazole, sulfhydryl, etc. and they may exert specific physiological roles in animal, microbial, insect and plant cells. This introductory chapter reviews the applications of protein hydrolysates in biotechnology. The word biotechnology is so broad and for the purpose of this book, we define it as a set of technologies such as cell culture technology, bioprocessing technology that includes fermentations, genetic engineering technology, microbiology, and so on. This chapter provides introduction and leads to other chapters on manufacturing and applications of protein hydrolysates in biotechnology.

Biotechnological uses of enzymes from psychrophiles

Summary The bulk of the Earth's biosphere is cold (e.g. 90% of the ocean's waters are ≤ 5°C), sustaining a broad diversity of microbial life. The permanently cold environments vary from the deep ocean to alpine reaches and to polar regions. Commensurate with the extent and diversity of the ecosystems that harbour psychrophilic life, the functional capacity of the microorganisms that inhabitat the cold biosphere are equally diverse. As a result, indigenous psychrophilic microorganisms provide an enormous natural resource of enzymes that function effectively in the cold, and these cold‐adapted enzymes have been targeted for their biotechnological potential. In this review we describe the main properties of enzymes from psychrophiles and describe some of their known biotechnological applications and ways to potentially improve their value for biotechnology. The review also covers the use of metagenomics for enzyme screening, the development of psychrophilic gene expression systems and the use of enzymes for cleaning. PMID:21733127

We estimate the trend in average height of the population of the French province Orleans from 1715 to the beginning of the 19th century using data on recruits who were drafted either through a lottery system or through general conscription. After controlling for age, residence, and occupation, we find a general decline in the biological standard of living in the decades before the French Revolution. The results support a Ricardian-Malthusian interpretation of the causes of the French Revolution. In the debate 'Revolution de la misère ou de la prospérité' our findings support the side which argues that the French Revolution was a culmination of a long-lasting economic malaise during the final phases of the Ancien Régime.

This year is a special year for plant biotechnology. It was 30 years ago, on January 18 1983, one of the most important dates in the history of plant biotechnology, that three independent groups described Agrobacterium tumefaciens-mediated genetic transformation at the Miami Winter Symposium, leading to the production of normal, fertile transgenic plants (Bevan et al. in Nature 304:184-187, 1983; Fraley et al. in Proc Natl Acad Sci USA 80:4803-4807, 1983; Herrera-Estrella et al. in EMBO J 2:987-995, 1983; Vasil in Plant Cell Rep 27:1432-1440, 2008). Since then, plant biotechnology has rapidly advanced into a useful and valuable tool and has made a significant impact on crop production, development of a biotech industry and the bio-based economy worldwide.

Thailand faces a significant burden in terms of treating and managing degenerative and chronic diseases. Moreover, incidences of rare diseases are rising. Many of these-such as diabetes, cancer, and inherited inborn metabolic diseases-have no definite treatments or cure. Meanwhile, advanced health biotechnology has been found, in principle, to be an effective solution for these health problems. Qualitative approaches were employed to analyse the current situation and examine existing public policies related to advanced health biotechnologies in Thailand. The results of this analysis were then used to formulate policy recommendations. Our research revealed that the system in Thailand in relation to advanced health biotechnologies is fragmented, with multiple unaddressed gaps, underfunding of research and development (R&D), and a lack of incentives for the private sector. In addition, there are no clear definitions of advanced health biotechnologies, and coverage pathways are absent. Meanwhile, false advertising and misinformation are prevalent, with no responsible bodies to actively and effectively provide appropriate information and education (I&E). The establishment of a specialised institution to fill the gaps in this area is warranted. The development and implementation of a comprehensive national strategic plan related to advanced health biotechnologies, greater investment in R&D and I&E for all stakeholders, collaboration among agencies, harmonisation of reimbursement across public health schemes, and provision of targeted I&E are specifically recommended.

The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

Toward a Rethinking of the Relativity Revolution

NASA Astrophysics Data System (ADS)

Siegel, Daniel

2014-03-01

This journey in the history of physics is offered in celebration of David Cassidy's Pais Prize. The journey, undertaken in part with the community of historians of physics and in part not, starts from a conventional characterization of the relativity revolution as an abrupt transition, in 1905, from pre-Einsteinian darkness to Einsteinian light, and ends with an alternative perspective on the relativity revolution, seeing it as a process extending over 50 years, in two phases: first, the protorelativity phase, lasting from the early 1880s to 1905, and involving initial treatments of the length contraction, the mass increase, and invariance properties; second, the Einsteinian phase, beginning with his recasting of the basic theoretical framework--with the inclusion now of the time dilation and the E = mc2 relationship--and continuing with the ensuing competition between the protorelativistic and Einsteinian approaches, issuing in the final triumph of the Einsteinian approach only in the early 1930s. A proper appreciation of the character and importance of the protorelativity phase of the relativity revolution is relevant to a variety of contexts: for the teaching of relativity theory, it makes available a more concrete and pictorial approach to the relativistic effects--retaining greater (length contraction) or somewhat lesser (mass increase) validity to the present day; for the ongoing discourse on the nature of scientific revolutions, it provides a perspective on the intricacies and complexities of those occurrences, and on the elements of continuity and gradualism in even the most radical changes; and for our general understanding of historical process in the history of the sciences, it shows the importance of the broader scientific research community for even the most individual accomplishments.

This paper describes the microgravity biotechnology experiments carried out on the Shuttle/Mir program. Four experiments investigated the growth of protein crystals, and three investigated cellular growth. Many hundreds of protein samples were processed using four different techniques. The objective of these experiments was to determine optimum conditions for the growth of very high quality single crystals to be used for structure determination. The Biotechnology System (BTS) was used to process the three cell growth investigations. The samples processed by these experiments were: bovine chondrocytes, human renal epithelial cells, and human breast cancer cells and endothelial cells. The objective was to determine the unique properties of cell aggregates produced in the microgravity environment.

Corynebacteria belong to the high G+C Gram-positive bacteria (Actinobacteria) and are closely related to Mycobacterium and Nocardia species. The best investigated member of this group of almost seventy species is Corynebacterium glutamicum, a soil bacterium isolated in 1957, which is used for the industrial production of more than two million tons of amino acids per year. This review focuses on the technical advances made in proteomics approaches during the last years and summarizes applications of these techniques with respect to C. glutamicum metabolic pathways and stress response. Additionally, selected proteome applications for other biotechnologically important or pathogenic corynebacteria are described. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Rational selection of alternative, environmentally compatible surfactants for biotechnological production of pharmaceuticals--a step toward green biotechnology.

PubMed

Straub, Jürg Oliver; Shearer, Russel; Studer, Martin

2014-09-01

The biotechnological production of pharmaceutical active substances needs ancillary substances. Surfactants are used at the end of the cell culture as a protection against potential viral or bacterial contamination and to lyse the producing cells for isolation and purification of the products. To find a replacement for a surfactant that had raised environmental concern, environmentally relevant data for potential alternatives were searched for in the literature. Significant data gaps were filled with additional tests: biodegradability, algal growth inhibition, acute daphnid immobilization and chronic daphnid reproduction toxicity, acute fish toxicity, and activated sludge respiration inhibition. The results were used to model removal in the wastewater treatment plants (WWTPs) serving 3 biotechnological production sites in the Roche Group. Predicted environmental concentrations (PECs) were calculated using realistic amounts of surfactants and site-specific wastewater fluxes, modeled removals for the WWTPs and dilution factors by the respective receiving waters. Predicted no-effect concentrations (PNECs) were derived for WWTPs and for both fresh and marine receiving waters as the treated wastewater of 1 production site is discharged into a coastal water. This resulted in a spreadsheet showing PECs, PNECs, and PEC ÷ PNEC risk characterization ratios for the WWTPs and receiving waters for all investigated surfactants and all 3 sites. This spreadsheet now serves as a selection support for the biotechnological developers. This risk-based prioritization of surfactants is a step toward green biotechnological production. © 2014 SETAC.

Microalgae constitute a diverse group of eukaryotic unicellular organisms that are of interest for pure and applied research. Owing to their natural synthesis of value-added natural products microalgae are emerging as a source of sustainable chemical compounds, proteins and metabolites, including but not limited to those that could replace compounds currently made from fossil fuels. For the model microalga, Chlamydomonas reinhardtii, this has prompted a period of rapid development so that this organism is poised for exploitation as an industrial biotechnology platform. The question now is how best to achieve this? Highly advanced industrial biotechnology systems using bacteria and yeasts were established in a classical metabolic engineering manner over several decades. However, the advent of advanced molecular tools and the rise of synthetic biology provide an opportunity to expedite the development of C. reinhardtii as an industrial biotechnology platform, avoiding the process of incremental improvement. In this review we describe the current status of genetic manipulation of C. reinhardtii for metabolic engineering. We then introduce several concepts that underpin synthetic biology, and show how generic parts are identified and used in a standard manner to achieve predictable outputs. Based on this we suggest that the development of C. reinhardtii as an industrial biotechnology platform can be achieved more efficiently through adoption of a synthetic biology approach. Significance Statement Chlamydomonas reinhardtii offers potential as a host for the production of high value compounds for industrial biotechnology. Synthetic biology provides a mechanism to generate generic, well characterised tools for application in the rational genetic manipulation of organisms: if synthetic biology principles were adopted for manipulation of C. reinhardtii, development of this microalga as an industrial biotechnology platform would be expedited.

Hua Loo-Keng's Popularization of Mathematics and the Cultural Revolution.

PubMed

Hudeček, Jiří

2017-09-01

Before 1966, Chinese mathematician Hua Loo-Keng had singled out "Two Methods" as a way to truly applied and useful mathematics. The Overall Planning Method, based on the Critical Path Method widely used in USA, mostly appealed to middle and upper management. This limited its spread during the Cultural Revolution. The Optimum Selection Method, also of US origin, was more mass-oriented and ready for popularization. Nevertheless, Hua met resistance from leftist radicals, whose ideological objections sprang from an underlying power struggle. Hua built popularization teams, mostly from talented younger people whose careers were disrupted by the Cultural Revolution, and thus opened a path for many of them to important roles in China's scientific infrastructure after 1976. Hua Loo-Keng's efforts, while interrupted during the Cultural Revolution and the subsequent political campaigns, were also helped by the populist ethos of the movement, and by the lack of other non-political endeavors at that time. In this sense, the Cultural Revolution gave Hua Loo-Keng's popularization its importance and long-term impact. Copyright © 2017 Elsevier Ltd. All rights reserved.

Ex-ante evaluation of biotechnology innovations: the case of folate biofortified rice in China.

PubMed

De Steur, Hans; Blancquaert, Dieter; Gellynck, Xavier; Lambert, Willy; Van Der Straeten, Dominique

2012-12-01

In order to valorize novel biotechnology innovations, there is a need to evaluate ex-ante their market potential. A case in point is biofortification, i.e. the enhancement of the micronutrient content of staple crops through conventional or genetic breeding techniques. In a recent article in Nature Biotechnology, for example, De Steur et al. (2010) demonstrated the large potential consumer health benefits of folate biofortified rice as a means to reduce folate deficiency and Neural-Tube Defects. By focusing on a Chinese high-risk region of Neural-Tube Defects, the current study defines the potential cost-effectiveness of this genetically modified crop where the need to improve folate intake levels is highest. Building on the Disability-Adjusted Life Years (DALY) approach, both the potential health impacts and costs of its implementation are measured and benchmarked against similar innovations. The results show that this transgenic crop could be a highly cost-effective product innovation (US$ 120.34 - US$ 40.1 per DALY saved) to alleviate the large health burden of folate deficiency and reduce the prevalence of neural-tube birth defects. When compared with other biofortified crops and target regions, folate biofortified rice in China has a relatively high health impact and moderate cost-effectiveness. This research further supports the need for, and importance of ex-ante evaluation studies in order to adequately market and, thus, valorize biotechnology innovations. Although the cost-effectiveness analysis enables to illustrate the market potential of innovative agricultural biotechnology research, further research is required to address policy issues on transgenic biofortification, such as biosafety regulatory requirements.

Biotechnological methods have become an important tool in pharmaceutical drug research and development. Today approximately 15 % of drug revenues are derived from biopharmaceuticals. The most relevant indications are oncology, metabolic disorders and disorders of the musculoskeletal system. For the future it can be expected that the relevance of biopharmaceuticals will further increase. Currently, the share of substances in preclinical testing that rely on biotechnology is more than 25 % of all substances in preclinical testing. Products for the treatment of cancer, metabolic disorders and infectious diseases are most important. New therapeutic approaches such as RNA interference only play a minor role in current commercial drug research and development with 1.5 % of all biological preclinical substances. Investments in sustainable high technology such as biotechnology are of vital importance for a highly developed country like Germany because of its lack of raw materials. Biotechnology helps the pharmaceutical industry to develop new products, new processes, methods and services and to improve existing ones. Thus, international competitiveness can be strengthened, new jobs can be created and existing jobs preserved.

Biotechnology regulation: is policy transfer an appropriate answer?

PubMed

Cárdenas-Gómez, Olga Carolina; Létourneau, Lyne

2010-01-01

In the world of biotechnology regulation, one often encounters the suggestion that the legislation of other countries should be consulted. Known as "policy transfer" in the field of public policy analysis, the purpose of such a recommendation is for policymakers to use the experiences of other States as a basis for developing appropriate regulatory frameworks in a timely manner. This paper examines whether policy transfer is relevant as an instrument for biotechnology regulation, and if it is, to what extent. Our analysis uses the example of Assisted Reproductive Technologies (ART), and unfolds according to the following argumentative steps. We will begin by discussing policy transfer as a recognized feature of policymaking in the literature pertaining to public policy analysis. We will then introduce a distinction between the technical dimension of policymaking and its political component. We will refer to "morality policy" as an illustration of policymaking directed toward its political component. We will show that, in the case of morality policy, States have moved away from a policy transfer approach. We will then establish that ART qualifies as morality policy, suggesting that policy transfer is most likely not the optimal policymaking tool for dealing with biotechnology regulation. Moving beyond the issue of ART in order to expand our reasoning to biotechnology regulation as a whole, we will conclude that, although the experiences of other States may be useful, policy transfer does not suffice in terms of informing policymaking in the case of biotechnology advances.

New biotechnological applications for Ashbya gossypii: Challenges and perspectives

PubMed Central

2017-01-01

ABSTRACT The filamentous fungus Ashbya gossypii has long been considered a paradigm of the White Biotechnology in what concerns riboflavin production. Its industrial relevance led to the development of a significant molecular and in silico modeling toolbox for its manipulation. This, together with the increasing knowledge of its genome and metabolism has helped designing effective metabolic engineering strategies for optimizing riboflavin production, but also for developing new A. gossypii strains for novel biotechnological applications, such as production of recombinant proteins, single cell oils (SCOs), and flavour compounds. With the recent availability of its genome-scale metabolic model, the exploration of the full biotechnological potential of A. gossypii is now in the spotlight. Here, we will discuss some of the challenges that these emerging A. gossypii applications still need to overcome to become economically attractive and will present future perspectives for these and other possible biotechnological applications for A. gossypii.

As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

Innovator Organizations in New Drug Development: Assessing the Sustainability of the Biopharmaceutical Industry.

PubMed

Kinch, Michael S; Moore, Ryan

2016-06-23

The way new medicines are discovered and brought to market has fundamentally changed over the last 30 years. Our previous analysis showed that biotechnology companies had contributed significantly to the US Food and Drug Administration approval of new molecular entities up to the mid-1980s, when the trends started to decline. Although intriguing, the focus on biotechnology necessarily precluded the wider question of how the biopharmaceutical industry has been delivering on its goals to develop new drugs. Here, we present a comprehensive analysis of all biopharmaceutical innovators and uncover unexpected findings. The present biopharmaceutical industry grew steadily from 1800 to 1950 and then stagnated for two decades, before a burst of growth attributable to the biotechnology revolution took place; but consolidation has reduced the number of active and independent innovators to a level not experienced since 1945. The trajectories and trends we observe raise fundamental questions about biopharmaceutical innovators and the sustainability of the drug-development enterprise. Copyright © 2016 Elsevier Ltd.

The biotechnology/materials interaction dates back 3.5 billion years, yet today offers novel challenges for human creativity. The materials cycle practiced by microorganisms is compared to that recently practiced by humans. The processes of the biotechnology materials cycle are biogenesis, bioleaching, biofouling, biocorrosion, biodeterioration, and bioaccumulation. Each process is examined for mechanisms, scale of effect, and opportunity for creative human intervention or utilization. More than 50 of our metallic elements are bio-processed in nature. A like number of biogenic materials have been identified, with some at production rates of trillions of kg per annum (p.a.). Microorganisms can substitute for energy, capital, and labor. Over the eons, microorganisms have gained special attributes that now offer creative humans a new era of partnership in materials processing.

The history of bariatric surgery is investigational. Dedicated surgeons have continuously sought for an ideal procedure to relieve morbidly obese patients from their burden of comorbid conditions, reduced life expectancy and low quality of life. The ideal procedure must have low complication risk, both in short- and long term, as well as minimal impact on daily life. The revolution of laparoscopic techniques in bariatric surgery is described in this summary. Advances in minimal invasive techniques have contributed to reduced operative time, length of stay, and complications. The development in bariatric surgery has been exceptional, resulting in a dramatic increase of the number of procedures performed world wide during the last decades. Although, a complex bariatric procedure can be performed with operative mortality no greater than cholecystectomy, specific procedure-related complications and other drawbacks must be taken into account. The evolution of laparoscopy will be the legacy of the 21st century and at present, day-care surgery and further reduction of the operative trauma is in focus. The impressive effects on comorbid conditions have prompted the adoption of minimal invasive bariatric procedures into the field of metabolic surgery. PMID:25386062

White rot fungi are essential in forest ecology and are deeply involved in wood decomposition and the biodegradation of various xenobiotics. The fungal ligninolytic enzymes involved in these processes have recently become the focus of much attention for their possible biotechnological applications. Successful bioremediation requires the selection of species with desirable characteristics. In this study, 150 taxonomically and physiologically diverse white rot fungi, including 55 species, were investigated for their performance in a variety of biotechnological procedures, such as dye decolorization, gallic acid reaction, ligninolytic enzymes, and tolerance to four PAHs, phenanthrene, anthracene, fluoranthene, and pyrene. Among these fungi, six isolates showed the highest (>90%) tolerance to both individual PAH and mixed PAHs. And six isolates oxidized gallic acid with dark brown color and they rapidly decolorized RBBR within ten days. These fungi revealed various profiles when evaluated for their biotechnological performance to compare the capability of degradation of PAHs between two groups selected. As the results demonstrated the six best species selected from gallic acid more greatly degraded four PAHs than the other isolates selected via tolerance test. It provided that gallic acid reaction test can be performed to rank the fungi by their ability to degrade the PAHs. Most of all, Peniophora incarnata KUC8836 and Phlebia brevispora KUC9033 significantly degraded the four PAHs and can be considered prime candidates for the degradation of xenobiotic compounds in environmental settings.

Reproductive biotechnology has manifold applications and includes a great innovation potential in livestock. Due to the global changes the new findings and techniques can aid to meet the future challenges. The use of biotechnology in animal production can guarantee enough high quality food for the whole population. Genetic resources of animals can be preserved via sperm and embryo banking. Early diagnosis of hereditary defects, generation of offspring with predetermined sex and the avoidance of animal transports for breeding employing shipment of frozen embryos will improve animal welfare. A special application is the use of animal models for human assisted reproductive technologies. Therefore, not only in Germany research related to the methodologies in reproductive biotechnology and their improvement need to be supported.

Potential flow about elongated bodies of revolution

NASA Technical Reports Server (NTRS)

Kaplan, Carl

1936-01-01

This report presents a method of solving the problem of axial and transverse potential flows around arbitrary elongated bodies of revolution. The solutions of Laplace's equation for the velocity potentials of the axial and transverse flows, the system of coordinates being an elliptic one in a meridian plane, are given. The theory is applied to a body of revolution obtained from a symmetrical Joukowsky profile, a shape resembling an airship hull. The pressure distribution and the transverse-force distribution are calculated and serve as examples of the procedure to be followed in the case of an actual airship. A section on the determination of inertia coefficients is also included in which the validity of some earlier work is questioned.

New crops are gradually establishing along with cultivation systems to reduce reliance on depleting fossil fuel reserves and sustain better adaptation to climate change. These biological assets could be efficiently exploited as bioenergy feedstocks. Bioenergy crops are versatile renewable sources with the potential to alternatively contribute on a daily basis towards the coverage of modern society's energy demands. Biotechnology may facilitate the breeding of elite energy crop genotypes, better suited for bio-processing and subsequent use that will improve efficiency, further reduce costs, and enhance the environmental benefits of biofuels. Innovative molecular techniques may improve a broad range of important features including biomass yield, product quality and resistance to biotic factors like pests or microbial diseases or environmental cues such as drought, salinity, freezing injury or heat shock. The current review intends to assess the capacity of biotechnological applications to develop a beneficial bioenergy pipeline extending from feedstock development to sustainable biofuel production and provide examples of the current state of the art on future energy crops.

2012-01-01

The completion of the Human Genome Project and the development of genome-based technologies over the past decade have set the stage for a new era of personalized medicine. By all rights, molecularly trained investigative pathologists should be leading this revolution. Singularly well suited for this work, molecular pathologists have the rare ability to wed genomic tools with unique diagnostic skills and tissue-based pathology techniques for integrated diagnosis of human disease. However, the number of pathologists with expertise in genome-based research has remained relatively low due to outdated training methods and a reluctance among some traditional pathologists to embrace new technologies. Moreover, because budding pathologists may not appreciate the vast selection of jobs available to them, they often end up choosing jobs that focus almost entirely on routine diagnosis rather than new frontiers in molecular pathology. This review calls for changes aimed at rectifying these troubling trends to ensure that pathology continues to guide patient care in a post-genomic era.

This article discusses why Chinese space programs were able to develop to the extent they did during the turbulent decade of the Cultural Revolution (1966-1976). It first introduces briefly what China had accomplished in rocket and missile technology before the Cultural Revolution, including the establishment of a system for research and manufacturing, breakthroughs in rocket technology, and programs for future development. It then analyzes the harmful impacts of the Cultural Revolution on Chinese space programs by examining activities of contemporary mass factions in the Seventh Ministry of Machinery Industry. In the third section, this article presents the important developments of Chinese space programs during the Cultural Revolution and explores briefly the significance of these developments for the future and overall progress in space technology. Finally, it discusses the reasons for the series of developments of Chinese space technology during the Cultural Revolution. This article concludes that, although the Cultural Revolution generated certain harmful impacts on the development of Chinese space technology, the Chinese essentially accomplished their scheduled objectives in their space program, both because of the great support of top Chinese leaders, including the officially disgraced Lin Biao and the Gang of Four, and due to the implementation of many effective special measures.

This article traces back thirty years of biotechnology research sponsored by the European Union (EU). It outlines the crucial role played by De Nettancourt, Goffeau and Van Hoeck to promote and prepare the first European programme on biotechnology (1982-1986) run by the European Commission. Following this first biotechnology programme, others followed until the current one, part of the seventh Framework Programme for Research, Technological Development and Demonstration (2007-2013) (FP7). Particular attention is given to the statutory role of the European institutions in the design and orientation of the successive biotechnology programmes, compared to the more informal-yet visionary-role of key individuals upstream to any legislative decision. Examples of success stories and of the role of the biotechnology programmes in addressing societal issues and industrial competitiveness are also presented. Finally, an outline of Horizon 2020, the successor of FP7, is described, together with the role of biotechnology in building the bioeconomy. Copyright © 2012 Elsevier B.V. All rights reserved.

Considerations for conducting research in agricultural biotechnology.

PubMed

Shelton, Anthony M

2003-06-01

Science has shown its increased vulnerability because of two recent high-profile articles published in major journals on corn produced through biotechnology: a laboratory report suggesting profound consequences to monarch butterfly populations due to Bt corn pollen and a report suggesting transgenic introgression into Mexican maize. While both studies have been widely regarded as having flawed methodology, publishing these studies has created great consternation in the scientific community, regulatory agencies and the general public. There are roles and responsibilities of scientists, scientific journals, the public media, public agencies, and those who oppose or advocate a specific technology, and serious consequences when those roles and responsibilities go awry. Modern communication may exacerbate the flow of misinformation and easily lead to a decline in public confidence about biotechnology and science. However, common sense tells us that scientific inquiry and the publication and reporting of results should be performed with high standards of ethical behavior, regardless of one's personal perspective on agricultural biotechnology.

Independent Biotechnology: The Innovation-Regulation Dilemma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Althouse, P.; Prosnitz, D.; Velsko, S.

The Center for Global Security Research at Lawrence Livermore National Laboratory convened a workshop on August 19, 2016 to consider “Independent Biotechnology: The Innovation-­Regulation Dilemma”. The topic was motivated by the observation that non-­government funded biotechnology research and development activities have grown and diversified tremendously over the past decade. This sector encompasses a broad range of actors and activities: individuals with private laboratories, community “hackerspaces,” biotechnology incubators, and individual startups. Motivations and aspirations are diverse and include such things as personal curiosity, community education, the invention of new products or services, and even the realization of certain economic, political, ormore » social goals. One driving force is the “democratization” of ever more powerful biological technologies, allowing individual citizens and groups access to capabilities that have traditionally only been available to researchers in universities, research institutes, national laboratories, and large commercial concerns. Another is the rise of alternative financing mechanisms such as “crowdsourcing,” which ostensibly provide greater freedom to innovate, and greater public visibility, but entail looser management oversight and transparency.« less

Rittmann, Bruce E

2006-06-01

Microbial ecology and environmental biotechnology are inherently tied to each other. The concepts and tools of microbial ecology are the basis for managing processes in environmental biotechnology; and these processes provide interesting ecosystems to advance the concepts and tools of microbial ecology. Revolutionary advancements in molecular tools to understand the structure and function of microbial communities are bolstering the power of microbial ecology. A push from advances in modern materials along with a pull from a societal need to become more sustainable is enabling environmental biotechnology to create novel processes. How do these two fields work together? Five principles illuminate the way: (i) aim for big benefits; (ii) develop and apply more powerful tools to understand microbial communities; (iii) follow the electrons; (iv) retain slow-growing biomass; and (v) integrate, integrate, integrate.

Biofuel Production Based on Carbohydrates from Both Brown and Red Macroalgae: Recent Developments in Key Biotechnologies

2016-01-01

Marine macroalgae (green, red and brown macroalgae) have attracted attention as an alternative source of renewable biomass for producing both fuels and chemicals due to their high content of suitable carbohydrates and to their advantages over terrestrial biomass. However, except for green macroalgae, which contain relatively easily-fermentable glucans as their major carbohydrates, practical utilization of red and brown macroalgae has been regarded as difficult due to the major carbohydrates (alginate and mannitol of brown macroalgae and 3,6-anhydro-l-galactose of red macroalgae) not being easily fermentable. Recently, several key biotechnologies using microbes have been developed enabling utilization of these brown and red macroalgal carbohydrates as carbon sources for the production of fuels (ethanol). In this review, we focus on these recent developments with emphasis on microbiological biotechnologies. PMID:26861307

EDITORIAL: The next photonic revolution The next photonic revolution

NASA Astrophysics Data System (ADS)

Zheludev, Nikolay I.

2009-11-01

This special section on Nanophotonics and Metamaterials is a follow-up to the second European Topical Meeting of the NANOMETA series of meetings (see www.nanometa.org) which took place on 5-8 January 2009, in Seefeld, Austria. The main idea of the first NANOMETA meeting held in 2007 was to bring together the mature community of microwave electrical engineers with the emerging community of photonics researchers interested in the physics of light coupled to nanostructures. In recent years the research landscape has shifted dramatically. A wider proliferation of nanofabrication techniques such as electron beam lithography, nanoimprint and focused ion beam milling, diagnostics techniques such as near-field scanning imaging, cathodoluminescence with nanoscale resolution and micro-spectrometry, and the availability of affordable broadband and ultrafast optical sources, have moved the research focus of the NANOMETA community to the optical domain. Quite naturally the ideas of the nonlinearity of materials and the coherency of light in the nanoscale realm have been widely discussed. Driven by the dream of untapped device and material functionality, nonlinear and switchable nanophotonic devices and photonic metamaterials, along with the concept of tailoring the electromagnetic space with metamaterials, appear to be the main avenues along which the subject will develop in the coming years. Indeed, in the last 20 years photonics has played a key role in creating the world as we know it, with enormous beneficial social impact worldwide. It is impossible to imagine modern society without the globe-spanning broadband internet and mobile telephony made possible by the implementation of optical fibre core networks, optical disc data storage (underpinned by the development of compact semiconductor lasers), modern image display technologies and laser-assisted manufacturing. We now anticipate that the next photonic revolution will continue to grow, explosively fuelled by a new

2013-12-01

The Egyptian Revolution 2011 has shaken the Arab world and stirred up Middle-East politics. Moreover, it caused a rush in political science and the neighboring disciplines, which had not predicted an event like this and now have troubles explaining it. While many things can be learned from the popular uprising, and from the limitations of previous scholarship, our focus will be on a moral resource, which has occasionally been noticed, but not sufficiently explored: the role of humor in keeping up the spirit of the Revolution. For 18 days, protestors persevered at Liberation Square in Central Cairo, the epicenter of resistance; at times a few dozens, at times hundreds of thousands. What they did was to fight the terror of the regime, which reached absurd peaks during those days, with humor-successfully. We offer a social-functionalist account of the uprising, which includes behavioral as well as cultural levels of analysis, and illuminates how humorous means helped to achieve deadly serious goals. By reconstructing how Egyptians laughed themselves into democracy, we outline a social psychology of resistance, which uses humor both as a sword and a shield.

Blue biotechnology, in which aquatic environments provide the inspiration for various products such as food additives, aquaculture, biosensors, green chemistry, bioenergy, and pharmaceuticals, holds enormous promise. Large-scale efforts to sequence aquatic genomes and metagenomes, as well as campaigns to isolate new organisms and culture-based screenings, are helping to push the boundaries of known organisms. Mass spectrometry-based proteomics can complement 16S gene sequencing in the effort to discover new organisms of potential relevance to blue biotechnology by facilitating the rapid screening of microbial isolates and by providing in depth profiles of the proteomes and metaproteomes of marine organisms, both model cultivable isolates and, more recently, exotic non-cultivable species and communities. Proteomics has already contributed to blue biotechnology by identifying aquatic proteins with potential applications to food fermentation, the textile industry, and biomedical drug development. In this review, we discuss historical developments in blue biotechnology, the current limitations to the known marine biosphere, and the ways in which mass spectrometry can expand that knowledge. We further speculate about directions that research in blue biotechnology will take given current and near-future technological advancements in mass spectrometry. Copyright © 2014 Elsevier B.V.

Ecology and Biotechnology of Selenium-Respiring Bacteria

PubMed Central

2015-01-01

SUMMARY In nature, selenium is actively cycled between oxic and anoxic habitats, and this cycle plays an important role in carbon and nitrogen mineralization through bacterial anaerobic respiration. Selenium-respiring bacteria (SeRB) are found in geographically diverse, pristine or contaminated environments and play a pivotal role in the selenium cycle. Unlike its structural analogues oxygen and sulfur, the chalcogen selenium and its microbial cycling have received much less attention by the scientific community. This review focuses on microorganisms that use selenate and selenite as terminal electron acceptors, in parallel to the well-studied sulfate-reducing bacteria. It overviews the significant advancements made in recent years on the role of SeRB in the biological selenium cycle and their ecological role, phylogenetic characterization, and metabolism, as well as selenium biomineralization mechanisms and environmental biotechnological applications.

2013-01-01

A workshop entitled "Challenges and Opportunities in Evaluating Protein Allergenicity across Biotechnology Industries" was held at the 51st Annual Meeting of the Society of Toxicology (SOT) in San Francisco, California. The workshop was sponsored by the Biotechnology Specialty Section of SOT and was designed to present the science-based approaches used in biotechnology industries to evaluate and regulate protein allergenicity. A panel of experts from industry and government highlighted the allergenicity testing requirements and research in the agricultural, pharmaceutical/biopharma, and vaccine biotechnology industries and addressed challenges and opportunities for advancing the science of protein allergenicity. The main learning from the workshop was that immunoglobulin E-mediated allergenicity of biotechnology-derived products is difficult to assess without human data. The approaches currently being used to evaluate potential for allergenicity across biotechnology industries are very different and range from bioinformatics, in vitro serology, in vivo animal testing, in vitro and in vivo functional assays, and "biosimilar" assessments (ie, biotherapeutic equivalents to innovator products). The challenge remains with regard to the different or lack of regulatory requirements for allergenicity testing across industries, but the novel approaches being used with bioinformatics and biosimilars may lead to opportunities in the future to collaborate across biotechnology industries.

Biological drugs have been used since the middle of the last century in medicine. Nowadays we are witnesses of the intensive development and wider administration of these drugs in clinical practice. Around 250 biological drugs are available and more than 350 million patients have been treated since their marketed authorization. Among the biologics there are protein based macromolecules, which mass production can be performed with the help of biotechnology. This term referring to the use of living organisms for production of molecules, was introduced by the Hungarian engineer, Károly Ereky. The present review focuses on the research, production and development of monoclonal antibodies manufactured by biotechnology. Some steps of this development have changed our immunological knowledge and the outcome of several diseases. The development of antibodies was highly recognized by two Nobel prizes. Authors detail the structure and functions of immunoglobulins, and their development, including fully human monoclonal antibodies. The RANKL inhibitor denosumab, a fully human IgG2 monoclonal antibody belongs to this latter group and it is available for treatment of osteoporosis. Authors also summarize the basic process of bone metabolism and the benefits of RANK ligand inhibition.

Australian Undergraduate Biotechnology Student Attitudes towards the Teaching of Ethics

NASA Astrophysics Data System (ADS)

Lysaght, Tamra; Rosenberger, Philip J., III; Kerridge, Ian

2006-08-01

In recent years, ethics has become part of most tertiary biotechnology curricula. There is, however, considerable variation in the extent and manner of ethics education provided to students in different institutions. In addition, the perceived need that students and employers have regarding ethics education, and the aims and expected outcomes of ethics education, are rarely made clear. This research reports the findings of a questionnaire administered to 375 undergraduate biotechnology students from 19 Australian universities to determine their attitudes towards the teaching of ethics. The results suggest that undergraduate biotechnology students generally regard ethics education to be important and that ethics should be included in undergraduate biotechnology curricula. Students tended, however, to emphasize the professional and industrial side of ethics and not to recognize the personal effects of morals and behaviour. We provide suggestions for rethinking how ethics should be taught.

The biotechnology and bioeconomy landscape in Malaysia.

PubMed

Arujanan, Mahaletchumy; Singaram, Muthu

2018-01-25

Since 1990s Malaysia aspired to make biotechnology and bioeconomy as her engines of economic growth to utlise the abundance of natural resources and biodiversity. The public sector plays an integral role in developing the sector and various incentives are in place for the private sector to be actively involved and to forge collaboration with the public sector. The country launched its National Biotechnology Policy in 2005 and later launched its National Bioeconomy Programme in 2010 to become the first country in South East Asia and second in Asia after China to have such an initiative. Malaysia is also very proactive in its biosafety law and regulations and has most of the related legal instrument in place. A lot of success has been recorded since the inception of the National Biotechnology Policy in terms of job creation, contribution to GDP through biobusinesses and investment from foreign companies, but the sector is not spared from challenges too. Due to the nature of the discipline that is multidisciplinary and that requires huge amount of investment, expertise and political will, there are a lot of barriers before the country emerges as a bioeconomy player. This paper discusses the public policies, initiatives and funding mechanisms in place in Malaysia that drive its research, development and commercialisation in the area of biotechnology and bioeconomy. The authors also discuss the challenges faced in Malaysia in implementing the policies. Copyright © 2017 Elsevier B.V. All rights reserved.

The ocean is considered to be a great reservoir of biodiversity. Microbial communities in marine environments are ecologically relevant as intermediaries of energy, and play an important role in nutrient regeneration cycles as decomposers of dead and decaying organic matter. In this sense, marine-derived fungi can be considered as a source of enzymes of industrial and/or environmental interest. Fungal strains isolated from different substrates, such as invertebrates, decaying wood, seawater, sediments, and mangrove detritus, have been reported to be producers of hydrolytic and/or oxidative enzymes, with alginate lyase, amylase, cellulase, chitinase, glucosidase, inulinase, keratinase, ligninase, lipase, nuclease, phytase, protease, and xylanase being among the enzymes produced by fungi of marine origin. These enzymes present temperature and pH optima ranging from 35 to 70∘C, and 3.0 to 11.0, respectively. High-level production in bioreactors is mainly performed using submerged-state fermentation. Certain marine-derived fungal strains present enzymes with alkaline and cold-activity characteristics, and salinity is considered an important condition in screening and production processes. The adaptability of marine-derived fungi to oceanic conditions can be considered an attractive point in the field of fungal marine biotechnology. In this review, we focus on the advances in discovering enzymes from marine-derived fungi and their biotechnological relevance. PMID:25914680

Proteomics of industrial fungi: trends and insights for biotechnology.

2011-01-01

Filamentous fungi are widely known for their industrial applications, namely, the production of food-processing enzymes and metabolites such as antibiotics and organic acids. In the past decade, the full genome sequencing of filamentous fungi increased the potential to predict encoded proteins enormously, namely, hydrolytic enzymes or proteins involved in the biosynthesis of metabolites of interest. The integration of genome sequence information with possible phenotypes requires, however, the knowledge of all the proteins in the cell in a system-wise manner, given by proteomics. This review summarises the progress of proteomics and its importance for the study of biotechnological processes in filamentous fungi. A major step forward in proteomics was to couple protein separation with high-resolution mass spectrometry, allowing accurate protein quantification. Despite the fact that most fungal proteomic studies have been focused on proteins from mycelial extracts, many proteins are related to processes which are compartmentalised in the fungal cell, e.g. β-lactam antibiotic production in the microbody. For the study of such processes, a targeted approach is required, e.g. by organelle proteomics. Typical workflows for sample preparation in fungal organelle proteomics are discussed, including homogenisation and sub-cellular fractionation. Finally, examples are presented of fungal organelle proteomic studies, which have enlarged the knowledge on areas of interest to biotechnology, such as protein secretion, energy production or antibiotic biosynthesis.

Casanoves, Marina; González, Ángel; Salvadó, Zoel; Haro, Juan; Novo, Maite

2015-11-01

Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is an important consideration as they will become an influential collective as future teachers of the next generation of children. The attitudes toward science (and biotechnology) that teachers have affect their behavior and influence the way they implement their daily practice of science teaching in school. This study analyzes the attitudes and knowledge of Spanish preservice teachers toward biotechnology. We designed a new survey instrument that was completed by 407 university students who were taking official degree programs in preschool and primary education. Our results point out that although they are aware of biotechnology applications, topics concerning the structure of DNA, management of genetic information inside the cell, genetically modified organism technology and the use of microorganisms as biotechnological tools were not correctly answered. According to our attitude analysis, Spanish preservice teachers could be defined as opponents of genetically modified product acquisition, supporters of biotechnology for medical purposes and highly interested in increasing their knowledge about biotechnology and other scientific advances. Our results show a positive correlation between better knowledge and more positive attitudes toward biotechnology. A Spanish preservice teacher with positive attitudes toward biotechnology tends to be a student with a strong biology background who scored good marks in our knowledge test.

The Future of Bio-technology

Hosts of technologies, most notably in electronics, have been on the path of miniaturization for decades and in 2005 they have crossed the threshold of the nano-scale. Crossing the nano-scale threshold is a milestone in miniaturization, setting impressive new standards for component-packing densities. It also brings technology to a scale at which quantum effects and fault tolerance play significant roles and approaches the feasible physical limit form many conventional "top-down" manufacturing methods. I will suggest that the most formidable manufacturing problems in nanotechnology will be overcome and major breakthroughs will occur in a host of technologies, when nanotechnology converges with bio-technology; i.e. I will argue that the future of bio-technology is in nanotechnology. In 2005, methods in molecular biology, microscopy, bioinformatics, biochemistry, and genetic engineering have focused considerable attention on the nano-scale. On this scale, biology is a kind of recursive chemistry in which molecular recognition, self-assembly, self-organization and self-referencing context-control lead to the emergence of the complexity of structures and processes that are fundamental to all life forms. While we are still far from understanding this complexity, we are on the threshold of being able to use at least some of these biological properties for .technology. I will discuss the use of biomolecules, such as DNA, RNA, and proteins as "tools" for the bio-technologist of the future. More specifically, I will present in some detail an example of how we are using a genetically engineered 60-kDa protein (HSP60) from an organism living in near boiling sulfuric acid to build nano-scale templates for arranging metallic nanoparticles. These "extremophile" HSP60s self-assemble into robust double-ring structures called "chaperonins," which further assemble into filaments and arrays with nanometer accuracy. I will discuss our efforts to use chaperonins to organize quantum

The recent growth of biotechnology requires a wide range of expertise within the industry. Education is the primary platform for students to gain information and knowledge on biotechnology. In Malaysia where biotechnology is relatively new, education programs and courses must be tailored to meet the demands of the industry. A combination of theoretical knowledge as well as practical and industrial training is essential to ensure graduates are prepared for their career in the fields of biotechnology. Results from this study show that university students lack literacy on biotechnology information and access to facilities provided by the universities. This may be a significant contributing factor to the lack of knowledge and information amongst graduates. Furthermore comparative analysis on the biotechnology program in Malaysian universities with that of other countries show the need to restructure the program by offering more specialized courses as well as soft skills and business subjects. This is to meet the demands of the related professionals as well as the various branches that exist in the biotechnology industry. © 2015 The International Union of Biochemistry and Molecular Biology.

Low-Thrust Many-Revolution Trajectory Optimization via Differential Dynamic Programming and a Sundman Transformation

Low-thrust trajectories about planetary bodies characteristically span a high count of orbital revolutions. Directing the thrust vector over many revolutions presents a challenging optimization problem for any conventional strategy. This paper demonstrates the tractability of low-thrust trajectory optimization about planetary bodies by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to an orbit angle and performing the optimization with differential dynamic programming. Fuel-optimal geocentric transfers are computed with the transfer duration extended up to 2000 revolutions. The flexibility of the approach to higher fidelity dynamics is shown with Earth's J 2 perturbation and lunar gravity included for a 500 revolution transfer.

Profound socioeconomic pressures on medical student education have been catalogued extensively. These pressures include teaching patient shortages, teacher shortages, conflicting systems, and financial problems. Many of these problems have been caused by an unregulated free market affecting medicine overall, with market values sometimes overshadowing the academic values of education, research, and patient care. This has caused profound changes in the conduct of medical student education. Particularly important has been a reduction in the "gold standard" of teaching: direct student-teacher and supervised student-patient interaction, replaced by a potpourri of online and simulated modules. The aggregate of these changes constitutes a revolution that challenges whether medical schools, school buildings, classes, and dedicated faculty are even necessary. The author posits several recommendations in response to this revolution: (1) recognize the revolution as such, and carefully guide or abort it, lest its outcome be inadequate, inauthentic, or corrupt, (2) prioritize academic rather than business values, (3) ensure that funds allotted for education are used for education, (4) insist that medical schools, not industry, teach students, (5) value authentic education more than simulation, (6) adopt learner-centered teaching without misusing it, (7) maintain acceptable class attendance without requiring it, (8) provide, from the first school day, authentic, patient-centered medical education characterized by vertical integration, humanism, early patient exposure, biopsychosocial orientation, and physician role modeling, (9) ensure that third- and fourth-year students have rich patient-care responsibility, and 10) keep tenure. These actions would permit the preservation of an educational gold standard that justifies medical education's cost.

Underwhelmed: hyperbole, regulatory policy, and the genetic revolution.

PubMed

Caulfield, T

2000-05-01

Rapid advances in the field of genetics in recent years have caused some commentators to suggest the emergence of a "genetic revolution." Such advances have been both praised as the "future of medicine" and condemned for encouraging the acceptance in society of laissez-faire eugenics. Yet the effect of technological advances flowing from the science of genetics appear somewhat overstated as few products of the genetic revolution, particularly in the areas of gene therapy and genetic testing, have managed to satisfy scientists' expectations to date. Furthermore, misdirected regulation of such advances can exacerbate the social, legal, and ethical problems associated with genetics, particularly in the context of health care, where issues of human cloning and the use of premature genetic testing technologies dominate current public debate. In this article, the author criticizes the hyperbolic rhetoric surrounding the genetic revolution and calls for a more balanced and informed approach to the development of genetic policies and regulations. Such an approach should include substantial interdisciplinary debate and an active role on the part of government in the identification and communication of accurate information relating to the effects of recent technological advances in the field of genetics.

Selenium biomineralization for biotechnological applications.

Nancharaiah, Yarlagadda V; Lens, Piet N L

2015-06-01

Selenium (Se) is not only a strategic element in high-tech electronics and an essential trace element in living organisms, but also a potential toxin with low threshold concentrations. Environmental biotechnological applications using bacterial biomineralization have the potential not only to remove selenium from contaminated waters, but also to sequester it in a reusable form. Selenium biomineralization has been observed in phylogenetically diverse microorganisms isolated from pristine and contaminated environments, yet it is one of the most poorly understood biogeochemical processes. Microbial respiration of selenium is unique because the microbial cells are presented with both soluble (SeO(4)(2-) and SeO(3)(2-)) and insoluble (Se(0)) forms of selenium as terminal electron acceptor. Here, we highlight selenium biomineralization and the potential biotechnological uses for it in bioremediation and wastewater treatment. Copyright © 2015 Elsevier Ltd. All rights reserved.

Photosynthetic protists, also called microalgae, have been systematically studied for more than a century. However, only recently broad biotechnological applications have fostered a novel wave of research on their potentialities as sustainable resources of renewable energy as well as valuable industrial and agro-food products. At the recent VII European Congress of Protistology held in Seville, three outstanding examples of different research strategies on microalgae with biotechnological implications were presented, which suggested that integrative approaches will produce very significant advances in this field in the next future. In any case, intense research and the application of systems biology and genetic engineering techniques are absolutely essential to reach the full potential of microalgae as cell-factories of bio-based products and, therefore, could contribute significantly to solve the problems of biosustainability and energy shortage.

Toward a microbial Neolithic revolution in buildings.

PubMed

Thaler, David S

2016-03-29

The Neolithic revolution--the transition of our species from hunter and gatherer to cultivator--began approximately 14,000 years ago and is essentially complete for macroscopic food. Humans remain largely pre-Neolithic in our relationship with microbes but starting with the gut we continue our hundred-year project of approaching the ability to assess and cultivate benign microbiomes in our bodies. Buildings are analogous to the body and it is time to ask what it means to cultivate benign microbiomes in our built environment. A critical distinction is that we have not found, or invented, niches in buildings where healthful microbial metabolism occurs and/or could be cultivated. Key events affecting the health and healthfulness of buildings such as a hurricane leading to a flood or a burst pipe occur only rarely and unpredictably. The cause may be transient but the effects can be long lasting and, e.g., for moisture damage, cumulative. Non-invasive "building tomography" could find moisture and "sentinel microbes" could record the integral of transient growth. "Seed" microbes are metabolically inert cells able to grow when conditions allow. All microbes and their residue present actinic molecules including immunological epitopes (molecular shapes). The fascinating hygiene and microbial biodiversity hypotheses propose that a healthy immune system requires exposure to a set of microbial epitopes that is rich in diversity. A particular conjecture is that measures of the richness of diversity derived from microbiome next-generation sequencing (NGS) can be mechanistically coupled to--rather than merely correlated with some measures of--human health. These hypotheses and conjectures inspire workers and funders but an alternative is also consequent to the first Neolithic revolution: That the genetic uniformity of contemporary foods may also decrease human exposure to molecular biodiversity in a heath-relevant manner. Understanding the consequences--including the unintended

Biotechnologies for the management of genetic resources for food and agriculture.

Lidder, Preetmoninder; Sonnino, Andrea

In recent years, the land area under agriculture has declined as also has the rate of growth in agricultural productivity while the demand for food continues to escalate. The world population now stands at 7 billion and is expected to reach 9 billion in 2045. A broad range of agricultural genetic diversity needs to be available and utilized in order to feed this growing population. Climate change is an added threat to biodiversity that will significantly impact genetic resources for food and agriculture (GRFA) and food production. There is no simple, all-encompassing solution to the challenges of increasing productivity while conserving genetic diversity. Sustainable management of GRFA requires a multipronged approach, and as outlined in the paper, biotechnologies can provide powerful tools for the management of GRFA. These tools vary in complexity from those that are relatively simple to those that are more sophisticated. Further, advances in biotechnologies are occurring at a rapid pace and provide novel opportunities for more effective and efficient management of GRFA. Biotechnology applications must be integrated with ongoing conventional breeding and development programs in order to succeed. Additionally, the generation, adaptation, and adoption of biotechnologies require a consistent level of financial and human resources and appropriate policies need to be in place. These issues were also recognized by Member States at the FAO international technical conference on Agricultural Biotechnologies for Developing Countries (ABDC-10), which took place in March 2010 in Mexico. At the end of the conference, the Member States reached a number of key conclusions, agreeing, inter alia, that developing countries should significantly increase sustained investments in capacity building and the development and use of biotechnologies to maintain the natural resource base; that effective and enabling national biotechnology policies and science-based regulatory frameworks can

Undoubtedly, biotechnology has a tremendous impact on our daily lives. As a result of this and in parallel to the advancement of knowledge in this field of applied research, consumer awareness of the potential benefits and risks of this technology has steadily increased, leading to a thorough investigation of the public perception of biotechnology in the past years. Indeed, it has become clear that it is in the general interest of science and especially of applied research to inform the public of its advances. A promising next step is to strengthen biotechnology communication in scholastic institutions. In this paper, we investigate the perception of biotechnology in a specific target group, namely high-school students in the 16-20-year-old age range. We conducted a questionnaire-based survey on a total of 1410 students in six European countries to investigate students' perception, concern, scientific knowledge, and awareness. Our data revealed some unexpected patterns of acceptance and concern about biotechnology. Knowledge analysis indicated that pupils lack specific knowledge about biotechnological applications and their interest in biotechnology appeared to be linked to knowledge. Analysis of specific questions about teaching practices at schools suggests that a better targeted choice in media as vehicles for information together with selected speakers could be instrumental in increasing students' interest in science and more specifically in biotechnology.

Scientific pluralism and the Chemical Revolution.

Kusch, Martin

2015-02-01

In a number of papers and in his recent book, Is Water H2O? Evidence, Realism, Pluralism (2012), Hasok Chang has argued that the correct interpretation of the Chemical Revolution provides a strong case for the view that progress in science is served by maintaining several incommensurable "systems of practice" in the same discipline, and concerning the same region of nature. This paper is a critical discussion of Chang's reading of the Chemical Revolution. It seeks to establish, first, that Chang's assessment of Lavoisier's and Priestley's work and character follows the phlogistonists' "actors' sociology"; second, that Chang simplifies late-eighteenth-century chemical debates by reducing them to an alleged conflict between two systems of practice; third, that Chang's evidence for a slow transition from phlogistonist theory to oxygen theory is not strong; and fourth, that he is wrong to assume that chemists at the time did not have overwhelming good reasons to favour Lavoisier's over the phlogistonists' views.

A departure from cognitivism: Implications of Chomsky's second revolution in linguistics.

PubMed

Schoneberger, T

2000-01-01

In 1957 Noam Chomsky published Syntactic Structures, expressing views characterized as constituting a "revolution" in linguistics. Chomsky proposed that the proper subject matter of linguistics is not the utterances of speakers, but what speakers and listeners know. To that end, he theorized that what they know is a system of rules that underlie actual performance. This theory became known as transformational grammar. In subsequent versions of this theory, rules continued to play a dominant role. However, in 1980 Chomsky began a second revolution by proposing the elimination of rules in a new theory: the principles-and-parameters approach. Subsequent writings finalized the abandonment of rules. Given the centrality of rules to cognitivism, this paper argues that Chomsky's second revolution constitutes a departure from cognitivism.

Given the increasing commercial and clinical relevance of probiotic cultures, improving their stress tolerance profile and ability to overcome the physiochemical defences of the host is an important biological goal. Pathogenic bacteria have evolved sophisticated strategies to overcome host defences, interact with the immune system and interfere with essential host systems. We coin the term 'patho-biotechnology' to describe the exploitation of these valuable traits in biotechnology and biomedicine. This approach shows promise for the design of more technologically robust and effective probiotic cultures with improved biotechnological and clinical applications as well as the development of novel vaccine and drug delivery platforms.

Fitzsimons, Peter John

2007-01-01

Fundamental differences between current and past knowledge in the field of biotechnology mean that we now have at our disposal the means to irreversibly change what is meant by "human nature". This paper explores some of the ethical issues that accompany the (as yet tentative) attempt to increase scientific control over the human genetic code in…

Utilization of protein-rich residues in biotechnological processes.

A drawback of biotechnological processes, where microorganisms convert biomass constituents, such as starch, cellulose, hemicelluloses, lipids, and proteins, into wanted products, is the economic feasibility. Particularly the cost of nitrogen sources in biotechnological processes can make up a large fraction of total process expenses. To further develop the bioeconomy, it is of considerable interest to substitute cost-intensive by inexpensive nitrogen sources. The aim of this mini-review was to provide a comprehensive insight of utilization methods of protein-rich residues, such as fish waste, green biomass, hairs, and food waste. The methods described include (i) production of enzymes, (ii) recovery of bioactive compounds, and/or (iii) usage as nitrogen source for microorganisms in biotechnological processes. In this aspect, the utilization of protein-rich residues, which are conventionally considered as waste, allows the development of value-adding processes for the production of bioactive compounds, biomolecules, chemicals, and materials.

The epistemology of mathematical and statistical modeling: a quiet methodological revolution.

Rodgers, Joseph Lee

2010-01-01

A quiet methodological revolution, a modeling revolution, has occurred over the past several decades, almost without discussion. In contrast, the 20th century ended with contentious argument over the utility of null hypothesis significance testing (NHST). The NHST controversy may have been at least partially irrelevant, because in certain ways the modeling revolution obviated the NHST argument. I begin with a history of NHST and modeling and their relation to one another. Next, I define and illustrate principles involved in developing and evaluating mathematical models. Following, I discuss the difference between using statistical procedures within a rule-based framework and building mathematical models from a scientific epistemology. Only the former is treated carefully in most psychology graduate training. The pedagogical implications of this imbalance and the revised pedagogy required to account for the modeling revolution are described. To conclude, I discuss how attention to modeling implies shifting statistical practice in certain progressive ways. The epistemological basis of statistics has moved away from being a set of procedures, applied mechanistically, and moved toward building and evaluating statistical and scientific models.

Understanding public perceptions of biotechnology through the "Integrative Worldview Framework".

PubMed

De Witt, Annick; Osseweijer, Patricia; Pierce, Robin

2015-07-03

Biotechnological innovations prompt a range of societal responses that demand understanding. Research has shown such responses are shaped by individuals' cultural worldviews. We aim to demonstrate how the Integrative Worldview Framework (IWF) can be used for analyzing perceptions of biotechnology, by reviewing (1) research on public perceptions of biotechnology and (2) analyses of the stakeholder-debate on the bio-based economy, using the Integrative Worldview Framework (IWF) as analytical lens. This framework operationalizes the concept of worldview and distinguishes between traditional, modern, and postmodern worldviews, among others. Applied to these literatures, this framework illuminates how these worldviews underlie major societal responses, thereby providing a unifying understanding of the literature on perceptions of biotechnology. We conclude the IWF has relevance for informing research on perceptions of socio-technical changes, generating insight into the paradigmatic gaps in social science, and facilitating reflexive and inclusive policy-making and debates on these timely issues. © The Author(s) 2015.
