Astrobiology: A pathway to adult science literacy?  

NASA Astrophysics Data System (ADS)

Adult science illiteracy is widespread. This is concerning for astrobiology, or indeed any other area of science in the communication of science to public audiences. Where and how does this scientific illiteracy arise in the journey to adulthood? Two astrobiology education projects have hinted that science illiteracy may begin in high school. This relationship between high school science education and the public understanding of science is poorly understood. Do adults forget their science education, or did they never grasp it in the first place? A 2003 science education project raised these questions when 24 16-year-olds from 10 Sydney high schools were brought into contact with real science. The unexpected results suggested that even good high school science students have a poor understanding of how science is really undertaken in the field and in the laboratory. This concept is being further tested in a new high school science education project, aimed at the same age group, using authentic astrobiology cutting-edge data, NASA Learning Technologies tools, a purpose-built research Information and Communication Technology-aided learning facility and a collaboration that spans three continents. In addition, a first year university class will be tested for evidence of science illiteracy immediately after high school among non-science oriented but well-educated students.

Astrobiology  

NSDL National Science Digital Library

Astrobiology refers to the "origin, evolution, and distribution of life in the universe." Astrobiologists study extreme environments on Earth and characterize the life forms that occupy them. These environments provide Earthly analogues to environments on other planets, and a framework for thinking about the organisms that once did or may now inhabit them. This article provides an overview of this fascinating field of study, and a wealth of content information as it relates to Earth and space science.

Astrobiology  

NASA Technical Reports Server (NTRS)

Astrobiology is the study of the origins, evolution and distribution of life in the universe. It provides a biological perspective to many areas of NASA research, linking such endeavors as the search for habitable planets beyond our solar system, exploration missions to Mars and Europa, and efforts to understand the origin and early evolution of life. Astrobiology addresses three fundamental questions: How does life begin and develop? Does life exist elsewhere in the universe? What is the future of life on Earth and beyond? This talk will address our concepts about the definition of life, how life might have begun, and how our blaspheme and planet have co-evolved for billions of years. The talk will explore how the perspectives gained from interdisciplinary research in the biological, geological and space sciences will prepare us to search for habitable environments and biospheres elsewhere in the Universe.

The Astrobiology Graduate Conference - A Unique Early Career Opportunity  

NASA Astrophysics Data System (ADS)

The Astrobiology Graduate Conference (AbGradCon) is an extremely successful annual meeting of early career researchers and educators involved and interested in the field of astrobiology. The conference has been held eight times in various locations, each time organized by a different group of students. The primary objective of AbGradCon is to stimulate the future of astrobiology research by bringing together graduate students and early post-doctoral fellows in order to create and strengthen interdisciplinary and international networks of early-career astrobiologists who will lead such research in the years to come. The conference is unique in that it is a student-led meeting, from the organization to the presentations. AbGradCon strives to remove the "pressures" of typical scientific meetings by providing a relaxed atmosphere in which presentations and round-table discussions are fostered along with numerous social activities. The success of previous AbGradCons can be attributed to the sheer enthusiasm of the participants for astrobiology, and to the spirit and format of the conference, which is outlined in a charter written by past conference organizers and participants. Because it is organized and attended by only graduate students and early career astrobiologists, AbGradCon is an ideal venue for the next generation of early career astrobiologists to form bonds, share ideas, and discuss the issues that will shape the future of the field.

Engaging in Science through Astrobiology Outreach  

NASA Astrophysics Data System (ADS)

There has been a steady decline in the number of Australian students studying science at the senior high school level. By the time students reach this point in their education, when they can choose whether or not to continue to study science, many have already decided that science is not for them. It is possible that students in the junior high school years may be gaining a false view of the world of science due to the disparity between the way that science is portrayed in schools and "real" science. A study is being undertaken to explore whether engaging in real science through outreach activities may increase students' understanding of the nature and processes of science, and whether such activities may heighten students' interest in science and potentially lead to an increase in the number of students studying science at the tertiary level. The study examines three astrobiology-related outreach programs, two in Australia and one in the US. The features of the programs are described and results from the Australian research carried out to date are presented.

Astrobiology  

NASA Astrophysics Data System (ADS)

If we believe life to be a cosmic imperative, the understanding of life processes becomes a universal aspect of cosmology. How does life fit into our understanding of the universe. As a compliment to NASA's `Origins' Program we are developing a new venture to embark on one of the great scientific questions of our time, our origins, evolution and our destiny. NASA already deals with a number of related biological questions. We are introducing a new unifying approach to biology within the NASA... Astrobiology. Astrobiology is the study of the chemistry, physics and adaptations that influence the origin, evolution and destiny of life. We intent to raise the conscious level relating relevant biological questions to the formation and development of the universe through space missions and research programs. By linking certain aspects of exobiology, ecology, gravitational biology, and adding efforts in molecular biology, evolutionary biology, and planetary biology and joining this to Astronomy and planetology, we seek a deeper understanding of where the living process fits in to our cosmological theories. We do this through laboratory experiments, space observations, computer modeling, missions and discovery of what appear to be extreme conditions for us, but conditions in which life thrives. NASA has formed an international `virtual' Astrobiology Institute as a nucleus to initiate this consolidating idea. NASA's technology will play a major role in this endeavor.

Astrobiology in culture: the search for extraterrestrial life as "science".  

PubMed

This analysis examines the social construction of authority, credibility, and legitimacy for exobiology/astrobiology and, in comparison, the search for extraterrestrial intelligence (SETI), considering English-language conceptions of these endeavors in scientific culture and popular culture primarily in the United States. The questions that define astrobiology as a scientific endeavor are multidisciplinary in nature, and this endeavor is broadly appealing to public audiences as well as to the scientific community. Thus, it is useful to examine astrobiology in culture-in scientific culture, official culture, and popular culture. A researcher may explore science in culture, science as culture, by analyzing its rhetoric, the primary means that people use to construct their social realities-their cultural environment, as it were. This analysis follows this path, considering scientific and public interest in astrobiology and SETI and focusing on scientific and official constructions of the two endeavors. This analysis will also consider whether and how scientific and public conceptions of astrobiology and SETI, which are related but at the same time separate endeavors, converge or diverge and whether and how these convergences or divergences affect the scientific authority, credibility, and legitimacy of these endeavors.

Remote Chemical Analysis at Enceladus: An Astrobiology Science Instrument Concept  

NASA Astrophysics Data System (ADS)

An instrument concept is being developed for the future exploration of Enceladus where remote chemical analysis would be performed onboard a spacecraft while in flight. The instrument will look for evidence for the presence of life in a subsurface ocean habitat by examining nascent ice grains collected by flying the spacecraft directly through the plume or jets of Enceladus. This astrobiology science instrument concept is compatible with an Enceladus sample return mission or a Saturn system orbiter mission. Described are 5 science tiers supported by the instrument system with a mass spectrometer at its core. Results for automation of sample pre-concentration and optical detection of free amino acids will also be presented and discussed as a pathway for assessing the inventory of organic molecules in a potentially inhabited ice covered Enceladus ocean. Concept for the Enceladus Amino Acid Sampler, an astrobiology science instrument system with 5 distinct science tiers for exploring the Enceladus subsurface composition.

Vanguard: A New Science Mission For Experimental Astrobiology  

NASA Astrophysics Data System (ADS)

As an alternative to technically and financially problemat ic sample return missions, a rover-mounted laser Raman spectrometer sensitive to biomolecules and their mineral substrata is a promising alternative in the search for evidence of former life on Mars. We presented a new remote in situ analysis package being designed for experimental astrobiology on terrestrial-type planetary surfaces. The science is based on the hypothesis that if life arose on Mars, the selective pressure of solar radiation would have led to the evolution of pigmented systems to harness the energy of sunlight and to protect cells from concurrent UV stress. Microbial communities would have therefore become stratified by the light gradient, and our remote system would penetrate the near-subsurface profile in a vertical transect of horizontal strata in ancient sediments (such as palaeolake beds). The system will include an extensive array of robotic support to translocate and deploy a Raman spectrometer detectors beneath the surface of Mars ­ it will comprise of a base station lander to support communications, a robotic micro-rover to permit well- separated triplicate profiles made by three ground-penetrating moles mounted in a vertical configuration. Each mole will deploy a tether carrying fibre optic cables coupling the Raman spectrometer onboard the rover and the side-scanning sensor head on the mole. The complete system has been named Vanguard, and it represents a close collaboration between a space robotics engineer (Ellery), an astrobiologist (Wynn-Williams), a molecular spectroscopist (Edwards), an opto-electronic technologist (Dickensheets), a spacecraft engineer (Welch) and a robotic vision specialist (Curley). The autonomy requirement for the Vanguard instrument requires that significant scientific competence is imparted to the instrument through an expert system to ensure that quick-look analysis is performed onboard in real-time as the mole penetrates beneath the surface. Onboard decision-making must be implemented to assess the need for further integrations on the basis of prior sensory data ­ Vanguard is essentially conceived to be a robotic field astrobiologist. In targetting the Martian sub-surface, Vanguard represents the obvious next step in the astrobiological investigation of Mars for Europe, with field trials in Antarctica. A more challenging application of a modified Vanguard instrument might be the astrobiological investigation of the near surface of Europa (with trials in Lake Vostok, Antarctica) if recent allegations concerning the significance of salts in the Europan ice are correct.

Astrobiology Outreach and the Nature of Science: The Role of Creativity  

PubMed Central

Abstract There is concern in many developed countries that school students are turning away from science. However, students may be choosing not to study science and dismissing the possibility of a scientific career because, in the junior secondary years, they gain a false view of science and the work of scientists. There is a disparity between science as it is portrayed at school and science as it is practiced. This paper describes a study to explore whether engaging in science through astrobiology outreach activities may improve students' understanding of the nature and processes of science, and how this may influence their interest in a career in science. The results suggest that the students attending these Mars research–related outreach activities are more interested in science than the average student but are lacking in understanding of aspects of the nature of science. A significant difference was detected between pre- and posttest understandings of some concepts of the nature of science. Key Words: Science education—School science—Creativity—Nature and processes of science—Attitudes—Astrobiology. Astrobiology 12, 1143–1153.

One of the corner stones of the Research Platform on ExoLife, University of Vienna, Austria is public outreach and education with respect to astrobiology, exoplanets, and planetary sciences. Since 2009 several initiatives have been started by the Research Platform to concentrate the interest of students in and outside the University onto natural sciences. Astrobiology as a very interdisciplinary scientific discipline with questions like "Are we alone in the Universe?," "How unique is Earth as a planet?" or "How did life originate?" will fascinate youngsters and junior scientists (see [1]).

The NASA Astrobiology Institute - Minority Institution Research Support Program: Strengthening the Astrobiology Community  

NASA Astrophysics Data System (ADS)

This paper describes the history, purpose and successes of the NASA Astrobiology Institute Minority Institution Research Support Program (NAI-MIRS). This program is designed to provide support and training in astrobiology to a new generation of researchers from Minority Serving Institutions. The NAI-MIRS program provides sabbaticals, follow-up support, and travel opportunities for faculty and students from minority institutions. The purpose of this initiative is to increase the attendance and participation of underrepresented scientists in astrobiology research laboratories, at professional conferences, and as NAI Team members. As Minority Serving Institutions (MSIs) graduate a higher percentage of students of color entering graduate schools in science and engineering than their majority counterparts, support to MSIs from the NAI-MIRS program will encourage the growth of astrobiology-related programs at these institutions identifying talented researchers and providing an avenue to foster astrobiology research, increases awareness of astrobiology within minority communities. Achievements in astrobiology by the Minority Serving Institutions include the first direct detection of an extrasolar planet and a MSI graduate, LaTasha Taylor, featured in the journal Science as one of the first minority students to enter the NSF funded Astrobiology IGERT program. To date, the NAI-MIRS program has involved faculty members from the three major MSIs: Tribal Colleges and Universities, Historically Black Colleges and Universities, and Hispanic Serving Institutions and partnered with the Minority Institute Astrobiology Collaborative (MIAC).

Essays in the Non-Science Major Astrobiology Course  

NASA Astrophysics Data System (ADS)

The non-science major "Life in the Universe" class offers students many opportunities to explore topics such as whether or not to send manned missions to Mars, which jovian moon is a suitable candidate for harboring life, etc. Some of these topics are suited to being offered as projects. At Joliet Junior College, Joliet, IL, we offer this general education class every semester to around 40 students. We expect our students to complete three short essays in a semester, instead of doing one or two large projects. The essays enable students to be engaged more deeply with some aspects of the course than is usually possible in the classroom. Some of our essay topics are based on suggestions in the textbook, others have been developed by us. In this poster, we will report on the essay topics and the attitudes of our Fall 2013 and Spring 2014 students to such essays.

In this talk, I will give the AbGradCon attendees an overview of astrobiology activities ongoing at NASA as well as a brief description of the various funding programs and careers that they can pursue. After this, I will present to them the case that the future of the field is theirs to determine, and give input on how to effectively make astrobiology and NASA responsive to the needs of the community. This presentation will leverage my experiences leading various efforts in the early career astrobiology community, where I have served as a conference organizer, primer lead editor, community blogger, and unofficial liaison to NASA headquarters.

Tumbleweed: Wind-propelled Surficial Measurements for Astrobiology and Planetary Science  

NASA Technical Reports Server (NTRS)

Tumbleweed is a wind-propelled long-range vehicle based on well-developed and tested technology, instrumented to perform surveys Mars analog environments for habitability and suitable for a variety of missions on Mars. Tumbleweeds are light-weight and relatively inexpensive, making it very attractive for multiple deployments or piggy-backing on a larger mission. Tumbleweeds with rigid structures are also being developed for similar applications. Modeling and testing have shown that a 6 meter diameter Tumbleweed is capable of climbing 25 hills, traveling over 1 meter diameter boulders, and ranging over a thousand kilometers. Tumbleweeds have a potential payload capability of about 10 kilograms with approximately 10-20 Watts of power. Stopping for science investigations can also be accomplished using partial deflation or other braking mechanisms. Surveys for Astrobiology and other applications of tumbleweeds are shown.

Astrobiological stoichiometry.  

PubMed

Abstract Chemical composition affects virtually all aspects of astrobiology, from stellar astrophysics to molecular biology. We present a synopsis of the research results presented at the "Stellar Stoichiometry" Workshop Without Walls hosted at Arizona State University April 11-12, 2013, under the auspices of the NASA Astrobiology Institute. The results focus on the measurement of chemical abundances and the effects of composition on processes from stellar to planetary scales. Of particular interest were the scientific connections between processes in these normally disparate fields. Measuring the abundances of elements in stars and giant and terrestrial planets poses substantial difficulties in technique and interpretation. One of the motivations for this conference was the fact that determinations of the abundance of a given element in a single star by different groups can differ by more than their quoted errors. The problems affecting the reliability of abundance estimations and their inherent limitations are discussed. When these problems are taken into consideration, self-consistent surveys of stellar abundances show that there is still substantial variation (factors of ?2) in the ratios of common elements (e.g., C, O, Na, Al, Mg, Si, Ca) important in rock-forming minerals, atmospheres, and biology. We consider how abundance variations arise through injection of supernova nucleosynthesis products into star-forming material and through photoevaporation of protoplanetary disks. The effects of composition on stellar evolution are substantial, and coupled with planetary atmosphere models can result in predicted habitable zone extents that vary by many tens of percent. Variations in the bulk composition of planets can affect rates of radiogenic heating and substantially change the mineralogy of planetary interiors, affecting properties such as convection and energy transport.

Astrobiology in Mars exploration: from Viking to Mars Science Laboratory and beyond  

NASA Astrophysics Data System (ADS)

Two Viking missions, each with an orbiter and a lander, were launched in 1975. These missions provided us with a tremendous amount of information about Mars, but left us with the view of a barren red planet. In 1977, diverse and complex life was discovered in hydrothermal vents along the Galapagos Rift, a branch of the East Pacific Rise, broadening our intellectual understanding of what constitutes a habitable zone. Since that time, our concept of the limits to life has continued to shrink and the potential habitability of Mars has continued to expand. The possibility of life on Mars has become a scientific issue of profound importance and of public interest. The modern era of Mars exploration, starting with Mars Global Surveyor in 1996, has followed the strategy of progressive steps in improving our understanding of Mars, leading to missions that would determine whether life ever arose there (NASA 1994 special publication - 530, An Exobiology Strategy for Mars Exploration). Through a succession of orbital and landed missions, Mars has been discovered to have had standing bodies of water, transforming our imagined lifeless desert planet to one that has the potential for life in the past, or even the present. If Mars astrobiology investigations do not find evidence of life, nevertheless they would provide snapshots of the environmental conditions back through time to the earliest periods of the solar system, when life arose on Earth. The current lander in development, the Mars Science Laboratory, will be the first Mars Astrobiology mission since Viking. This 2011 mission is an extremely capable roving analytical laboratory with ten instruments and able to determine, elemental composition, mineralogy, and discover and characterize organic compounds. This mission sets the stage for the coming decade, as Mars exploration moves from the theme “follow the water” to “seek the signs of life”.

Astrobiology as a tool for getting high school students interested in science  

NASA Astrophysics Data System (ADS)

A workshop was held (10/99) for high school students and teachers on astrobiology. NASA provided support through an IDEAS grant. Out of 63 qualified applicants, 29 were accepted: 22 students (11 minorities) and 7 teachers. The worship was held on 2 successive weekends. Activities included: culturing microbes from human skin, discussing 'what is life?', building and using a 2-inch refractive telescope and a van-Leeuwenhoek- type microscope (each participant built and kept them), listening to lectures by Dr. Richard Gelderman on detecting extra solar planets and by Dr. Richard Hoover on life in extreme environments. Other activities included: collecting samples and isolating micro-organisms from the lost river cave, studying microbial life from extreme environments in the laboratory, using the internet as a research tool and debating the logistics and feasibility of a lunar colony. Written evaluations of the workshop led to the following conclusions: 48% of the students considered a possible career in the biological and/or astrophysical sciences, and half of these stated they were spurred on by the workshop itself.

Summer Research Experiences for Science and Art Teachers to Explore Astrobiology  

NASA Astrophysics Data System (ADS)

The Georgia Tech Center for Ribosomal Origins and Evolution, a center funded by the NASA Astrobiology Institute, developed an educational program titled, "Life on the Edge: Astrobiology." The purpose of the program was to provide high school educators with the exposure, materials, and skills necessary to prepare our future workforce and to foster student interest in scientific discovery on Earth and throughout the universe. In an effort to promote and encourage entry into teaching careers, Georgia Tech paired teachers in the Georgia Intern-Fellowship for Teachers (GIFT) program with undergraduate students interested in becoming a teacher through the NSF Pre-Teaching REU program. The GIFT and Pre-Teaching fellows investigated extremophiles, which became the focus of a week-long, "Life on the Edge: Astrobiology " summer program developed by three high school educators, two undergraduate students and faculty in the Schools of Biology, and Chemistry and Biochemistry at Georgia Tech. Twenty high school students were introduced to hands-on activities, such as astrobiology inspired art and techniques such as genomic DNA purification, gel electrophoresis, and Polymerase Chain Reaction (PCR). The impact of the Astrobiology program on the GIFT researchers, Pre-Teaching REU students, high school students, and faculty are discussed.

NASA Astrobiology Institute Scientist/Educator Bridges  

NASA Astrophysics Data System (ADS)

NASA has engaged in many educational programs and projects, and one major focus of the Office of Space Science's priorities in establishing education and public outreach (E/PO) programs has been the inclusion of scientists in those efforts. However, the construction of scientist/educator teams remains a major challenge in NASA education efforts. The NASA Astrobiology Institute (NAI) seeks to build bridges between these two professions in ways that are respectful of the expertise of each in bringing astrobiology content to K-12 classrooms. Several of the NAI's Lead Teams, collaborative interdisciplinary research groups pursuing core questions in astrobiology and providing education and training, include teachers and other experts in education to focus their E/PO efforts while also integrating the unique scientific expertise of their teams. This approach is not without its challenges and difficulties. Communication, accuracy, inclusion, funding, and the larger science education reform efforts are among them. There is tremendous work to be done in the arena of winning mutual respect and inclusion of both scientists and educators in providing NASA content to K-12 audiences. NAI is engaged in a series of attempts through the venues of both science and education conferences where such understanding may be built. This panel discussion represents one of these efforts.

Euro3D Science Conference  

NASA Astrophysics Data System (ADS)

The Euro3D RTN is an EU funded Research Training Network to foster the exploitation of 3D spectroscopy in Europe. 3D spectroscopy is a general term for spectroscopy of an area of the sky and derives its name from its two spatial + one spectral dimensions. There are an increasing number of instruments which use integral field devices to achieve spectroscopy of an area of the sky, either using lens arrays, optical fibres or image slicers, to pack spectra of multiple pixels on the sky (``spaxels'') onto a 2D detector. On account of the large volume of data and the special methods required to reduce and analyse 3D data, there are only a few centres of expertise and these are mostly involved with instrument developments. There is a perceived lack of expertise in 3D spectroscopy spread though the astronomical community and its use in the armoury of the observational astronomer is viewed as being highly specialised. For precisely this reason the Euro3D RTN was proposed to train young researchers in this area and develop user tools to widen the experience with this particular type of data in Europe. The Euro3D RTN is coordinated by Martin M. Roth (Astrophysikalisches Institut Potsdam) and has been running since July 2002. The first Euro3D science conference was held in Cambridge, UK from 22 to 23 May 2003. The main emphasis of the conference was, in keeping with the RTN, to expose the work of the young post-docs who are funded by the RTN. In addition the team members from the eleven European institutes involved in Euro3D also presented instrumental and observational developments. The conference was organized by Andy Bunker and held at the Institute of Astronomy. There were over thirty participants and 26 talks covered the whole range of application of 3D techniques. The science ranged from Galactic planetary nebulae and globular clusters to kinematics of nearby galaxies out to objects at high redshift. Several talks were devoted to reporting recent observations with newly completed 3D instruments - CIRPASS, GMOS, PMAS and SPIFFI. Work on 3D software, being developed as part of the Euro3D RTN, was also described and demonstrated. This proceedings volume, consisting of carefully refereed and edited manuscripts, represents the bulk of the talks at the conference and amply demonstrates that 3D spectroscopy is a lively and burgeoning field of optical observation.

The Living Universe: NASA and the Development of Astrobiology  

NASA Technical Reports Server (NTRS)

In the opening weeks of 1998 a news article in the British journal Nature reported that NASA was about to enter biology in a big way. A "virtual" Astrobiology Institute was gearing up for business, and NASA administrator Dan Goldin told his external advisory council that he would like to see spending on the new institute eventually reach $100 million per year. "You just wait for the screaming from the physical scientists (when that happens)," Goldin was quoted as saying. Nevertheless, by the time of the second Astrobiology Science Conference in 2002, attended by seven hundred scientists from many disciplines, NASA spending on astrobiology had reached nearly half that amount and was growing at a steady pace. Under NASA leadership numerous institutions around the world applied the latest scientific techniques in the service of astrobiology's ambitious goal: the study of what NASA's 1996 Strategic Plan termed the "living universe." This goal embraced nothing less than an understanding of the origin, history, and distribution of life in the universe, including Earth. Astrobiology, conceived as a broad interdisciplinary research program, held the prospect of being the science for the twenty-first century which would unlock the secrets to some of the great questions of humanity. It is no surprise that these age-old questions should continue into the twenty-first century. But that the effort should be spearheaded by NASA was not at all obvious to those - inside and outside the agency - who thought NASA's mission was human spaceflight, rather than science, especially biological science. NASA had, in fact, been involved for four decades in "exobiology," a field that embraced many of the same questions but which had stagnated after the 1976 Viking missions to Mars. In this volume we tell the colorful story of the rise of the discipline of exobiology, how and why it morphed into astrobiology at the end of the twentieth century, and why NASA was the engine for both the discipline's founding and for its transformation.

MBL Astrobiology  

NSDL National Science Digital Library

This MBL Astrobiology portal includes information about the MBL Astrobiology team, its personnel, prior work, and publications. The MBL Astrobiology team works toward understanding the patterns and mechanisms of genome evolution and metabolic variation that allowed diverse microorganisms to adapt to new environments, generate novel phenotypes, and effect global-scale changes detectable by remote sensing. Their general strategy emphasizes the integration of molecular approaches to evolutionary biology with studies of metabolic activities in environments that most likely reflect conditions on early Earth. Physiological and microbial diversity studies focus on the hydrothermally altered sediments of Guaymas basin in the Gulf of California, the acidic, heavy metal laden Rio Tinto of southwestern Spain and isolates from the Juan de Fuca Ridge.

Astrobiology Magazine  

NSDL National Science Digital Library

With a sponsor such as NASA and a tagline that reads, "Search for Life in the Universe", the bar is set fairly high for the online Astrobiology magazine, and the results are quite nice. Produced by Helen Matsos, the magazine has been in existence since 2001, and contains thousands of short pieces about a compelling variety of topics, including life on Mars, extrasolar life, stellar evolution, and climate. From the site's homepage, visitors can peruse articles, view a list of "hot topics", and sign up to receive new editions of the magazine as they are published electronically. The site also has several thematic areas, including the compelling one dedicated to art of astrobiology. Here, visitors can look at visualizations of terrestrial climate, representations of Mars in pop culture, and other such items. The site is rounded out by a very well-designed search engine and an "On this day in..." feature that provides information about important dates in astrobiology.

The Astrobiology Matrix and the "Drake Matrix" in Education  

NASA Technical Reports Server (NTRS)

We organized astrobiology lectures in the Eotvos Lorand University of Sciences and the Polaris Observatory in 2002. We present here the "Drake matrix" for the comparison of the astrobiological potential of different bodies [1], and astrobiology matrix for the visualization of the interdisciplinary connections between different fields of astrobiology. Conclusion: In Hungary it is difficult to integrate astrobiology in the education system but the great advantage is that it can connect different scientific fields and improve the view of students. We would like to get in contact with persons and organizations who already have experience in the education of astrobiology.

Astrobiological polarimeter.  

PubMed

Chirality is an excellent indicator of life, but naturally occurring astrobiological (as well as terrestrial) samples nearly always exhibit massive depolarizing light scattering, which renders conventional polarimeters useless. For astrobiological applications, we instead consider a novel polarimeter originally developed for non-invasive human-glucose measurement. It involves deliberately rotating in time the plane of polarization of a linearly polarized beam and detecting the shift in the plane of the rotating linearly polarized component of the transmitted light from a chiral sample relative to the input polarization plane. We find that this polarimeter can operate in 3 orders of magnitude more depolarizing scattering than conventional polarimeters. Furthermore, it can also be designed to be lightweight, compact, and energy efficient. PMID:19191536

Bridging Science and Policy: The AGU Science Policy Conference  

NASA Astrophysics Data System (ADS)

In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In June 2013, AGU held its second annual Science Policy Conference in Washington, D.C. The goal of the conference is to provide a new forum for diverse discussions and viewpoints on the challenges and opportunities of science policy, with a focus on applications of Earth and space science that serve local, national, and international communities. The meeting brought together more than 300 scientists, policy makers, industry professionals, members of the press, and other stakeholders to discuss the topics concerning the Arctic, climate change, oceans, energy, technology and infrastructure, and natural hazards science as they relate to challenges impacting society. Sessions such as 'The Water-Energy Nexus,' 'Potential for Megadisasters,' 'The Changing Ocean and Impacts on Human Health,' and 'Drowning and Drought: Agricultural Impacts of Climate Change' are examples of some of the intriguing and timely science policy issues addressed at the conference. The findings from the conference were used to develop a summary report. The report highlights key facts and figures to be used as a resource in discussions with policy makers and other stakeholders regarding the conference topics. This presentation will discuss the goals and outcomes of the conference and how the event represents one of the many ways AGU is approaching its 'Science and Society' priority objective as part of the Union's strategic plan; namely by increasing the effectiveness and recognition of AGU among policy makers as an authoritative source of integrated, interdisciplinary Earth and space science information.

PubMed

The Conference on Small Molecule Science (CoSMoS), organized by the Society for Small Molecule Science (a 501(c)(3) nonprofit chartered organization), was held in Portland, Oregon, USA, on the 27-29 September 2010. The meeting is focused on analytical scientists, from varied scientific and industrial backgrounds, to foster practical 'how to' discussions. CoSMoS organizes highly interactive workshop environments, where in addition to presentations of a unique topical value, a discussion of what has been tried and didn't work, including reasons why, is an instructive part of the proceedings. The conference included six plenary sessions and five workshop sessions. This year CoSMoS was jointly hosted with the 'small molecule' NMR spectroscopy meeting, SMASH, and the program for the final day represented a combination of topics spanning the two interdisciplinary groups.

Educational Outreach for Astrobiology  

NASA Astrophysics Data System (ADS)

Astrobiology, the search for life in the universe, has fascinating research areas that can excite students and teachers about science. Its integrative nature, relating to astronomy, geology, oceanography, physics, and chemistry, can be used to encourage students to pursue physical sciences careers. Since 2004, the University of Hawaii NASA Astrobiology Institute (NAI) team scientists have shared their research with secondary teachers at our ALI’I national teacher program to promote the inclusion of astrobiology topics into science courses. Since 2007, our NAI team has co-sponsored the HI STAR program for Hawaii’s middle and high school students to work on authentic astronomy research projects and to be mentored by astronomers. The students get images of asteroids, comets, stars, and extrasolar planets from the Faulkes Telescope North located at Haleakala Observatories on the island of Maui and owned by Las Cumbres Observatory Global Telescope network. They also do real time observing with DeKalb Observatory telescope personally owned by Donn Starkey who willing allows any student access to his telescope. Student project results include awards at the Hawaii State Science Fair and the Intel International Science and Engineering Fair. We believe that research experience stimulates these students to select STEM (science, technology, engineering and mathematics) majors upon entering college so a longitudinal study is being done. Plans are underway with California and Hawaii ALI’I teachers cooperating on a joint astronomy classroom project. International collaborations with Brazil, Portugal, and Italy astronomers have begun. We envision joint project between hemispheres and crossing time zones. The establishment of networking teachers, astronomers, students and educator liaisons will be discussed.

The narrative power of astrobiology  

NASA Astrophysics Data System (ADS)

The narrative power of astrobiology: Telling the story of the quest to understand life's origins and the search for evidence of extraterrestrial life INTRODUCTION The story of the origins and evolution of life is a narrative with nearuniversal appeal. The story of life on Earth is meaningful to all people, and the search for life elsewhere is appealing across cultural boundaries. The U.S. National Aeronautics and Space Administration (NASA) funds an Astrobiology Program in NASA's Science Mission Directorate that is dedicated to the study of the origin, evolution, distribution, and future of life in the universe. Because public interest in astrobiology is great and advances in the field are rapid, the NASA Astrobiology Program aims to integrate communication, education, and outreach into all aspects of program planning and execution. This strategic approach to communication is intended to promote the widest possible dissemination of timely and useful information about scientific discoveries, technology development, new knowledge, and greater understanding produced by the Astrobiology Program. This paper will address how scientists in the field of astrobiology can participate in the telling of an ongoing story of interest to multicultural audiences and why it is important to tell this story. SUMMARY Astrobiology research addresses three fundamental questions: How does life begin and evolve? Is there life beyond Earth and how can we detect it? What is the future of life on Earth and in the universe? The field of astrobiology is an endeavor that brings together researchers in a broad range of disciplines including Earth and planetary science, astrophysics, heliophysics, microbiology and evolutionary biology, and cosmochemistry. Goals of the NASA Astrobiology Program range from determining the nature and distribution of habitable environments in the Solar System and beyond to understanding the emergence of life from cosmic and planetary precursors, the interaction of past life on Earth with its changing environment, the formation and evolution of planets, links between planetary and biological evolution, the effects of climate and geology on habitability, and life's precursors and habitats in the outer solar system. Research dedicated to fulfilling these goals is conducted on Earth and in space, with a growing number of astrobiology investigations flying on planetary exploration missions. Since 1995, the field of astrobiology has grown rapidly, and the pace of discovery has been brisk. The possibility of extraterrestrial life is now a serious scientific question. Research findings over the past decade that are relevant to this question include the controversial 1996 claim of fossil evidence for microbial life in a martian meteorite, evidence of past and perhaps even present liquid water on Mars, the likelihood of a liquid water ocean on Europa, the possibility of liquid water beneath the surface of Titan, observations of a growing number of extrasolar planets, and identification of new forms of microbial life in an ever-widening range of extreme Earth environments. In the 21st century, the tempo of robotic planetary exploration is speeding up, and scientific and public attention is increasingly focusing on astrobiology research, especially the search for signs of life on Mars and other planetary bodies in our solar system. Mars is currently considered the best site in the solar system to search for evidence of past or present extraterrestrial life. And as Mars exploration proceeds, astrobiological interest in Enceladus, Europa, and Titan - outer solar system bodies that might have liquid water, prebiotic chemistry, or even life - is growing as new data are collected and analyzed. With an expanding array of solar system exploration endeavors involving and advancing astrobiology research, the NASA Astrobiology Program employs a communication strategy designed to establish that communication is an integral element of program planning and activities and an activity of fundamental importance to this scientific enterprise.

Astrobiology and Society: Building an Interdisciplinary Research Community  

PubMed Central

Abstract This paper reports recent efforts to gather experts from the humanities and social sciences along with astrobiologists to consider the cultural, societal, and psychological implications of astrobiology research and exploration. We began by convening a workshop to draft a research roadmap on astrobiology's societal implications and later formed a Focus Group on Astrobiology and Society under the auspices of the NASA Astrobiology Institute (NAI). Just as the Astrobiology Science Roadmap and various astrobiology science focus groups have helped researchers orient and understand their work across disciplinary contexts, our intent was to apply the same approach to examine areas beyond the physical and life sciences and expand interdisciplinary interaction and scholarly understanding. These efforts continue as an experiment in progress, with an open invitation to interested researchers—astrobiologists as well as scholars in the humanities and social sciences—to become involved in research, analysis, and proactive discussions concerning the potential impacts of astrobiology on society as well as the possible impacts of society on progress in astrobiology. Key Words: Astrobiology—Extraterrestrial life—Life detection. Astrobiology 12, 958–965.

Lower Secondary Students' Views in Astrobiology  

NASA Astrophysics Data System (ADS)

Astrobiology is, on a profound level, about whether life exists outside of the planet Earth. The question of existence of life elsewhere in the universe has been of interest to many societies throughout history. Recently, the research area of astrobiology has grown at a fast rate, mainly due to the development of observational methods, and the media is frequently reporting on new research findings. International surveys show that astrobiology questions are among those that interest young people the most. The popularity of astrobiology and the way it captures much science content makes it an interesting area for science teaching. However, there is very little research directly focused upon students' views in astrobiology. The study reported in this paper draws from the answers of 186 Swedish lower secondary students (16 years old) to a questionnaire, with closed and open-ended questions regarding their views of issues in astrobiology. The study was guided by the worldview theory (Cobern 1991; Cobern, Science Education 80(5):579-610, 1996; Cobern, Science and Education 9:219-246, 2000). The results show that even though basic reasoning in astrobiology is known by a majority of the students, there is a considerable number of students, for whom this is not the case. Furthermore, it was found that for all questions, there are students answering in different ways when asked to describe their own view and the view they associate with science researchers. The implications of the study for further research and for the teaching of astrobiology in science class are discussed.

Astro-Venture: An Integrated Earth and Space Science Curriculum Supplement Focused on Astrobiology  

NASA Astrophysics Data System (ADS)

Astro-Venture is an example of a NASA educational product that successfully integrates Earth and space science by engaging students in grades 5-8 in the search for and design of a planet with the necessary characteristics for human habitation. Students study the Earth to understand how it meets human needs for survival in the areas of astronomy, geology, biology and atmospheric sciences. They then extend these ideas in simulated searches and analyses of stellar and planetary data sets to determine whether other planets or moons might be habitable. Astro-Venture uses online multimedia activities and off-line inquiry explorations to engage students in guided inquiry aligned with the 5 E inquiry model. For each core science area, students engage in an online training module in which they isolate variables and observe the affects on Earth. They then draw conclusions about which characteristics allow Earth to remain habitable. Following this experience, students engage in classroom, hands-on activities that teach them core standards-based concepts and focus on why the identified characteristics are vital to human habitability. These concepts include: states of matter, flow of energy, chemical properties, planetary geology, plate tectonics, human health and systems theory. With an understanding of the "whats" and the "whys" students then engage in a mission module in which they simulate the methods scientists would use to go about finding a planet with these characteristics. This helps them to understand the "hows". By meeting education standards, teachers can easily integrate this product into their classroom curriculum. Students apply all that they've learned to design a planet that meets the requirements for human habitability in all areas. Through this process, they learn about the Earth within the context of the solar system and how all parts work as a system in meeting our needs.

Astrosociological Implications of Astrobiology (Revisited)  

NASA Astrophysics Data System (ADS)

Supporters of astrobiology continue to organize the field around formalized associations and organizations under the guise of the so-called ``hard'' sciences (e.g., biology and the related physical/natural sciences). The so-called ``soft'' sciences-including sociology and the other social sciences, the behavioral sciences, and the humanities-remain largely separated from this dynamically growing field. However, as argued in this paper, space exploration involving the search for extraterrestrial life should be viewed as consisting of two interrelated parts (i.e., two sides of the same coin): astrobiology and astrosociology. Together, these two fields broadly combine the two major branches of science as they relate to the relationship between human life and alien life, as appropriate. Moreover, with a formalized system of collaboration, these two complimentary fields would also focus on the implications of their research to human beings as well as their cultures and social structures. By placing the astrosociological implications of astrobiology at a high enough priority, scientists interested in the search for alien life can augment their focus to include the social, cultural, and behavioral implications that were always associated with their work (yet previously overlooked or understated, and too often misunderstood). Recognition of the astrosociological implications expands our perception about alien life by creating a new emphasis on their ramifications to human life on Earth.

Assessment of the NASA Astrobiology Institute  

NASA Technical Reports Server (NTRS)

Astrobiology is a scientific discipline devoted to the study of life in the universe--its origins, evolution, distribution, and future. It brings together the physical and biological sciences to address some of the most fundamental questions of the natural world: How do living systems emerge? How do habitable worlds form and how do they evolve? Does life exist on worlds other than Earth? As an endeavor of tremendous breadth and depth, astrobiology requires interdisciplinary investigation in order to be fully appreciated and examined. As part of a concerted effort to undertake such a challenge, the NASA Astrobiology Institute (NAI) was established in 1998 as an innovative way to develop the field of astrobiology and provide a scientific framework for flight missions. Now that the NAI has been in existence for almost a decade, the time is ripe to assess its achievements. At the request of NASA's Associate Administrator for the Science Mission Directorate (SMD), the Committee on the Review of the NASA Astrobiology Institute undertook the assignment to determine the progress made by the NAI in developing the field of astrobiology. It must be emphasized that the purpose of this study was not to undertake a review of the scientific accomplishments of NASA's Astrobiology program, in general, or of the NAI, in particular. Rather, the objective of the study is to evaluate the success of the NAI in achieving its stated goals of: 1. Conducting, supporting, and catalyzing collaborative interdisciplinary research; 2. Training the next generation of astrobiology researchers; 3. Providing scientific and technical leadership on astrobiology investigations for current and future space missions; 4. Exploring new approaches, using modern information technology, to conduct interdisciplinary and collaborative research among widely distributed investigators; and 5. Supporting outreach by providing scientific content for use in K-12 education programs, teaching undergraduate classes, and communicating directly with the public. The committee s assessment of the NAI's progress in these five areas is presented in Chapters 2 to 6, respectively.

Analogs from LEO: Mapping Earth Observations to Planetary Science & Astrobiology. (Invited)  

NASA Astrophysics Data System (ADS)

If, as Charles Lyell articulated ‘the present is the key to the past’ for terrestrial geology, then perhaps by extension the Earth, our planet, is the key to understanding other planets. This is the basic premise behind planetary analogs. Many planetary science missions, however, utilize orbiters and are therefore constrained to remote sensing. This is the reverse of how we developed our understanding of Earth’s environments; remote sensing is a relatively new tool for understanding environments and processes on Earth. Here we present several cases and comparisons between Earth’s cryosphere and icy worlds of the outer Solar System (e.g. Europa, Titan, and Enceladus), where much of our knowledge is limited to remote observations (the sole exception being the Huygens probe to Titan). Three regions are considered: glaciers in the Sierra Nevada, the permafrost lakes of Alaska’s North Slope, and spreading centers of the ocean floor. Two key issues are examined: 1) successes and limitations for understanding processes that shape icy worlds, and 2) successes and limitations for assessing the habitability of icy worlds from orbit. Finally, technological considerations for future orbiting mission to icy worlds are presented.

Journey to the origins: the astrobiology paradigm in education  

NASA Astrophysics Data System (ADS)

Astrobiology is a new multi-disciplinary field of knowledge concerned with the study of the origin, distribution, and destiny of life in the universe and, naturally, in our planet. For this goal we must introduce and develop the adequate tools for teaching this science in schools and universities. New curricula, with a more open mind, must be established for the formation of the present and future generations of students and also, in our point of view, of teachers. One example of this effort can be seen in the Portuguese project A Journey to the Origins. Astrobiology in the Lab, where secondary school students recreate experiments regarding the Origin of Life and Cellular Evolution. The work will be widened to the educational community through the carrying out of Open Laboratory Sessions, conferences and the drawing up of a digital portfolio compiling all of the material developed by students and teachers throughout the project. A proposal will be made to restructure the curriculum to include a new unit entitled 'Astrobiology and Cellular Evolution'. The repercussions of this innovative paradigm could be seen in the future, not only in the educational community, but also in the society in general.

We tried to collect and assemble in a logical and thematical order the scientific breakthroughs of the last years, that made possible the fast improvement of astrobiology. The followings are a kind of summary of these. Introduction - The ultimate science Astrobiology is a young science, that search for the possibility, forms and places of extraterrestrial life. But it is not SETI, because do not search for intelligent life, just for living organisms, so SETI is a part of astrobiology. and an extremely important statement: we can search for life-forms that similar to terrestrial life in physiology so we can recognize it as life. Astrobiology is one of the most dynamical-developing sciences of the 21st century. To determine its boundaries is difficult because the complex nature of it: astrobiology melt into itself lot of other sciences, like a kind of ultimate science. The fundamental questions are very simple [2]: When, where and how converted the organic matter into life?; How does life evolve in the Universe?; Has it appeared on other planets?; How does it spread in time and space?; and What is the future of terrestrial life? However, trying to find the answers is quite difficult. So an astrobiologist has to be aware of the basics of astronomy, space research, earth and planetary sciences, and life sciences (mainly ecology, genetics, molecular and evolution biology). But it is not enough - the newest results of these at least as important as the basic knowledge. Part I. - Astro 1. Exoplanets 1995 was a particular year in astronomy: we have found the first planet out of the Solar System. Since that time the discovery of exoplanets progress fast: nowdays more than 80 examples are known and just 6 years passed [3]. The detailed analysis of these distant objects has verified and solidified our theo- ries of planet-formation. The places of this process are contacting clouds of gas and dust, like the Orion Nebula. In these star-birth clouds we can observe clusters of mat- ter in which the temperature and pressure reach a limit and a new-born star begin to "function", or rather radiate. Around the star, the remnant matter settle into a plane, 1 forming a protoplanetary disk. It has different zones: heavy elements nearer to the star, light elements farther from it. The planets are taking shape from these zones - perhaps rocky types and gas giants as well. To see so much example we can state that planetary system-formation is an absolutely normal, everyday process in the Universe. As a consequence there are a lot of planetary system near to our Earth, with planets orbiting around stars. Though, the known exoplanets are not too Earth-like objects. Most of them seems to be lonely gas giants (with mass bigger than our Jupiter) nearer to their star then rocky planets to our Sun (the only known multiple exoplanet sys- tem is around Upsilon Andromedae [4]). Probable the reason of this difference is the weak capability of our instrument and not the speciality of our system. By using ad- vanced methods and instruments (like Next Generation Space Telescope or Terrestrial Planet Finder spacecraft, planned to launch in 5 years [5]) rocky-like planets will be found as well. 2. Water in the Solar System Looking closer, the knowledge of our Solar System has increased intensively during the last years of the 20th century - due to the planetary spacecraft missions, like Lunar Prospector, Mars Pathfinder, Mars Global Surveyor, Galileo and NEAR-Shoemaker. The most important discovery, that liquid water is quite general in our local cosmic environment. and as we know this is the most important condition of life. First and foremost, the most important is Planet Mars. By reconstructing the surface evolution of our outer neighbor it seems that in the past, more billion years ago it had global ocean, the depressions were filled with sea

Astrobiology Undergraduate Education: Students' Knowledge and Perceptions of the Field  

NASA Astrophysics Data System (ADS)

With the field of astrobiology continually evolving, it has become increasingly important to develop and maintain an educational infrastructure for the next generation of astrobiologists. In addition to developing more courses and programs for students, it is essential to monitor the learning experiences and progress of students taking these astrobiology courses. At the University of Florida, a new pilot course in astrobiology was developed that targeted undergraduate students with a wide range of scientific backgrounds. Pre- and post-course surveys along with knowledge assessments were used to evaluate the students' perceived and actual learning experiences. The class incorporated a hybrid teaching platform that included traditional in-person and distance learning technologies. Results indicate that undergraduate students have little prior knowledge of key astrobiology concepts; however, post-course testing demonstrated significant improvements in the students' comprehension of astrobiology. Improvements were not limited to astrobiology knowledge. Assessments revealed that students developed confidence in science writing as well as reading and understanding astrobiology primary literature. Overall, student knowledge of and attitudes toward astrobiological research dramatically increased during this course, which demonstrates the ongoing need for additional astrobiology education programs as well as periodic evaluations of those programs currently underway. Together, these approaches serve to improve the overall learning experiences and perceptions of future astrobiology researchers.

The new discipline of astrobiology addresses fundamental questions about life in the universe: "Where did we come from?" "Are we alone in the universe?" "What is our future beyond the Earth?" Developing capabilities in biotechnology, informatics, and space exploration provide new tools to address these old questions. The U.S. National Aeronautics and Space Administration (NASA) has encouraged this new discipline by organizing workshops and technical meetings, establishing a NASA Astrobiology Institute, providing research funds to individual investigators, ensuring that astrobiology goals are incorporated in NASA flight missions, and initiating a program of public outreach and education. Much of the initial effort by NASA and the research community was focused on determining the technical content of astrobiology.

Astrobiology and society: building an interdisciplinary research community.  

PubMed

This paper reports recent efforts to gather experts from the humanities and social sciences along with astrobiologists to consider the cultural, societal, and psychological implications of astrobiology research and exploration. We began by convening a workshop to draft a research roadmap on astrobiology's societal implications and later formed a Focus Group on Astrobiology and Society under the auspices of the NASA Astrobiology Institute (NAI). Just as the Astrobiology Science Roadmap and various astrobiology science focus groups have helped researchers orient and understand their work across disciplinary contexts, our intent was to apply the same approach to examine areas beyond the physical and life sciences and expand interdisciplinary interaction and scholarly understanding. These efforts continue as an experiment in progress, with an open invitation to interested researchers-astrobiologists as well as scholars in the humanities and social sciences-to become involved in research, analysis, and proactive discussions concerning the potential impacts of astrobiology on society as well as the possible impacts of society on progress in astrobiology.

Visions for a sustainable world: A conference on science, technology and social responsibility. Conference report  

SciTech Connect

This report summarizes the organization, activities, and outcomes of Student Pugwash USA`s 1992 International Conference, Visions for a Sustainable World: A Conference on Science, Technology and Social Responsibility. The conference was held June 14--20, 1992 at Emory University, and brought together 94 students and over 65 experts from industry, academe, and government. The conference addressed issues ranging from global environmental cooperation to the social impacts of the Human Genome Project to minority concerns in the sciences. It provided a valuable forum for talented students and professionals to engage in critical dialogue on many interdisciplinary issues at the juncture of science, technology and society. The conference challenged students -- the world`s future scientists, engineers, and political leaders -- to think broadly about global problems and to devise policy options that are viable and innovative. The success of the conference in stimulating interest, understanding, and enthusiasm about interdisciplinary global issues is clearly evident from both the participants` feedback and their continued involvement in Student Pugwash USA programs. Six working groups met each morning. The working group themes included: environmental challenges for developing countries; energy options: their social and environmental impact; health care in developing countries; changing dynamics of peace and global security; educating for the socially responsible use of technology; ethics and the use of genetic information. The conference was specifically designed to include mechanisms for ensuring its long-term impact. Participants were encouraged to focus on their individual role in helping resolve global issues. This was achieved through each participant`s development of a Personal Plan of Action, a plan which mapped out activities the student could undertake after the conference to continue the dialogue and work towards the resolution of global and local problems.

Astrobiological phase transition  

NASA Astrophysics Data System (ADS)

Can astrophysics explain Fermi's paradox or the "Great Silence" problem (i.e., the absence of extraterrestrial intelligent agents or signs of their activities)? If available, such explanation would be advantageous over most of those suggested in literature which rely on untestable assumptions of technological, culturological or sociological nature. Recent advances in astrophysics and astrobiology present us with uniquely convenient starting point for advancing such an explanation. Hereby, we suggest a general astrobiological paradigm which might offer a physical and empirically testable solution of the "Great Silence" problem.

Astrobiological complexity with probabilistic cellular automata.  

PubMed

The search for extraterrestrial life and intelligence constitutes one of the major endeavors in science, but has yet been quantitatively modeled only rarely and in a cursory and superficial fashion. We argue that probabilistic cellular automata (PCA) represent the best quantitative framework for modeling the astrobiological history of the Milky Way and its Galactic Habitable Zone. The relevant astrobiological parameters are to be modeled as the elements of the input probability matrix for the PCA kernel. With the underlying simplicity of the cellular automata constructs, this approach enables a quick analysis of large and ambiguous space of the input parameters. We perform a simple clustering analysis of typical astrobiological histories with "Copernican" choice of input parameters and discuss the relevant boundary conditions of practical importance for planning and guiding empirical astrobiological and SETI projects. In addition to showing how the present framework is adaptable to more complex situations and updated observational databases from current and near-future space missions, we demonstrate how numerical results could offer a cautious rationale for continuation of practical SETI searches.

Cultural Aspects of Astrobiology: A Preliminary Reconnaissance at  

NASA Astrophysics Data System (ADS)

NASA's Astrobiology Roadmap, developed in 1998 by an interdisciplinary team of more than 150 individuals, recognizes ten science goals, 17 more specific science objectives, and four broad principles for the Astrobiology Program. Among the four operating principles, which emphasize multidisciplinarity, planetary stewardship and public outreach, is one that also recognizes broad societal interest for the implications of astrobiology, especially its extraterrestrial life component. Although several meetings ahve been convened in the past decade to discuss the implications of extraterrestrial intelligence, including NASA's own CASETI workshops in 1991-1992, none have surveyed the broader implications of astrobiology as now defined at NASA. In this paper we survey these societal questions raised by astrobiology, and then focus on those related to extraterrestrial life, and in particular how they might differ from SETI concerns already discussed. As we enter the new millennium, the necessity for interdisciplinary studies is increasingly recognized in academia, industry and government. Astrobiology provides an unprecedented opportunity to encourage the unity of knowledge, as recently proposed in E. O. Wilson's book Consilience: The Unity of Knowledge. It is incumbent on scientists to support research on the implications of their work, in particular large government-funded scientific projects. The deep insights such study may yield has been amply demonstrated by the Human Genome Project, among others.

The Astrobiology in Secondary Classrooms (ASC) curriculum: focusing upon diverse students and teachers.  

PubMed

The Minority Institution Astrobiology Collaborative (MIAC) began working with the NASA Goddard Center for Astrobiology in 2003 to develop curriculum materials for high school chemistry and Earth science classes based on astrobiology concepts. The Astrobiology in Secondary Classrooms (ASC) modules emphasize interdisciplinary connections in astronomy, biology, chemistry, geoscience, physics, mathematics, and ethics through hands-on activities that address national educational standards. Field-testing of the Astrobiology in Secondary Classrooms materials occurred over three years in eight U.S. locations, each with populations that are underrepresented in the career fields of science, technology, engineering, and mathematics. Analysis of the educational research upon the high school students participating in the ASC project showed statistically significant increases in students' perceived knowledge and science reasoning. The curriculum is in its final stages, preparing for review to become a NASA educational product. PMID:22984874

Astrobiology: The Case for Venus  

NASA Technical Reports Server (NTRS)

The scientific discipline of astrobiology addresses one of the most fundamental unanswered questions of science: are we alone? Is there life elsewhere in the universe, or is life unique to Earth? The field of astrobiology includes the study of the chemical precursors for life in the solar system; it also includes the search for both presently existing life and fossil signs of previously existing life elsewhere in our own solar system, as well as the search for life outside the solar system. Two of the promising environments within the solar system being currently considered are the surface of the planet Mars, and the hypothesized oceans underneath the ice covering the moon Europa. Both of these environments differ in several key ways from the environments where life is found on Earth; the Mars environment in most places too cold and at too low pressure for liquid water to be stable, and the sub-ice environment of Europa lacking an abundance of free energy in the form of sunlight. The only place in the solar system where we know that life exists today is the Earth. To look for life elsewhere in the solar system, one promising search strategy would be to find and study the environment in the solar system with conditions that are most similar to the environmental conditions where life thrives on the Earth. Specifically, we would like to study a location in the solar system with atmospheric pressure near one bar; temperature in the range where water is liquid, 0 to 100 C; abundant solar energy; and with the primary materials required for life, carbon, oxygen, nitrogen, and hydrogen, present. Other than the surface of the Earth, the only other place where these conditions exist is the atmosphere of Venus, at an altitude of about fifty kilometers above the surface.

UK Astrobiology : Vanguard: a new development in experimental astrobiology  

NASA Astrophysics Data System (ADS)

Alex Ellery and David Wynn-Williams propose a new UK astrobiology project, in which a micro-rover would deploy ground-penetrating moles to burrow into the Martian subsurface. One of the linchpins of the UK's contribution to the burgeoning field of astrobiology is the Beagle 2 mission, due to fly to Mars in 2003 on the Mars Express bus. Given that NASA has declared its intention to focus on ``whole planet'' geological investigation in its future Mars missions, beginning with the Mars Exploration Rovers which are due to fly in 2003/2004, the UK is well placed to consider post-Beagle 2 astrobiology-focused Mars missions to ensure its leadership in the future in astrobiology. In this paper we present such a proposal - Vanguard.

Proceedings of the Plutonium Futures ? The Science 2006 Conference  

SciTech Connect

Plutonium Futures--The Science 2006 provided opportunities to examine present knowledge of the chemical and physical properties of plutonium and other actinides in complex media and materials; to discuss the current and emerging science (chemistry, physics, materials science, nuclear science, and environmental effects) of plutonium and actinides relevant to enhancing global nuclear security; and to exchange ideas. This international conference also provided a forum for illustrating and enhancing capabilities and interests, and assessing issues in these areas. U.S. and international scientists, engineers, faculty, and students from universities, national laboratories, and DOE's nuclear complex were encouraged to participate and make technical contributions. The Conference ran from Sunday, July 9th through Thursday, July 13th. A popular aspect of the conference was the opening tutorial session on Sunday afternoon intended for students and scientists new to the area of plutonium research. The tutorial was well attended by novices and veterans alike, and featured such diverse topics as; plutonium metallurgy, plutonium in the environment, and international arms control and nonproliferation. Two plenary lectures began each morning and each afternoon session and highlighted the breakout sessions on coordination/organometallic chemistry, solid-state physics, environmental chemistry, materials science, separations and reprocessing, advanced fuels and waste forms, phase transformations, solution and gas-phase chemistry, compounds and complexes, electronic structure and physical properties, and more. Chemistry Highlights--Among the many chemistry highlights presented in this proceedings are the overview of concepts and philosophies on inert nuclear fuel matrices and concerns about the ever-increasing amounts of minor actinides and plutonium generated in the fuel cycle. The various ideas involve multiple reduction schemes for these materials, suggesting fuels for 'burning' or 'cradle-to-grave' accountability for various reactor types. Related work is presented on identification of the unique reaction mechanisms and identification of the intermediate products, including Pu(III), at the end of the PUREX process. In the important area of nuclear forensics, actual scenarios of nuclear materials confiscation and the successes of applying forensics protocols to determine attribution and possible intention are provided. In the area of reactor incidents, there is no other place on Earth like the Chernobyl Site Object Shelter and radioactive aerosol particle characterization studies reflect an important effort described herein. An additional report from another unique environmental site presents results on radionuclide monitoring, fate, and transport in the ecosystem of the Yenisei River in the Krasoyarsk region. In the area of nuclear waste disposal, a study of the ion irradiation damage to pyrochlore compounds with varying amounts of host elements and actinide dopants is presented. Papers on both the aqueous and nonaqueous chemistry of plutonium and other actinides are presented including anhydrous coordination chemistry and redox behavior in the presence of humic materials and the their sorption on common minerals in the environment. Also published herein are reports on the field of anhydrous coordination chemistry of the transuranic elements where there is scarce information. Solid-State and Materials Highlights--Plutonium solid-state and materials research is represented in these proceedings by a wealth of leading edge discovery class research. The breadth of this research is reflected in the topics covered: solid-state; materials science; superconductivity; phase changes, phonons, and entropy; electronic structure and physical properties; surface science and corrosion; and radiation effects, defects, impurities, and property changes. Indeed the scientific challenge and excitement of plutonium can best be highlighted by quoting the tutorial prospectus of Drs. Sarrao and Schwartz.

Vibrational Spectroscopy and Astrobiology  

NASA Technical Reports Server (NTRS)

Role of vibrational spectroscopy in solving problems related to astrobiology will be discussed. Vibrational (infrared) spectroscopy is a very sensitive tool for identifying molecules. Theoretical approach used in this work is based on direct computation of anharmonic vibrational frequencies and intensities from electronic structure codes. One of the applications of this computational technique is possible identification of biological building blocks (amino acids, small peptides, DNA bases) in the interstellar medium (ISM). Identifying small biological molecules in the ISM is very important from the point of view of origin of life. Hybrid (quantum mechanics/molecular mechanics) theoretical techniques will be discussed that may allow to obtain accurate vibrational spectra of biomolecular building blocks and to create a database of spectroscopic signatures that can assist observations of these molecules in space. Another application of the direct computational spectroscopy technique is to help to design and analyze experimental observations of ice surfaces of one of the Jupiter's moons, Europa, that possibly contains hydrated salts. The presence of hydrated salts on the surface can be an indication of a subsurface ocean and the possible existence of life forms inhabiting such an ocean.

Astrobiology Research in India - A Brief Overview  

NASA Astrophysics Data System (ADS)

strobiology is study of the origin, evolution, distribution and future of life on Earth and in the Universe. The discovery of amino acids in carbonaceous chondrite meteorites and complex organic molecules in interstellar clouds, comets and interplanetary dust forced biological interest into space research. The existence of different life forms in extreme environments of Earth, their ability to adapt and survive for long periods in stasis and then recover has given hope that life might exist on other planets. A lot more insight into the origin of life is gained by studying the analogous life on Earth to predict how extraterrestrial life might live. In this paper, a brief account is given on the exogenous and endogenous origin of life on Earth, biochemical basis of life, the need and approach for research in astrobiology, scientific strength of Indian institutions to launch space missions in search of life. A review of the results of the two balloon experiments carried out by Indian Space Research Organization (ISRO) in collaboration with many research institutes in the country as well as the studies carried out elsewhere is also given. An attempt made to address the limitations of the previous experiments, improvements needed, implications of engineering design changes to meet the gaps and institutional resources needed to carry out further studies in astrobiology in the Indian context. A few priority investigations that can be carried out in collaboration with premier national laboratories in India have been identified. A brief account of the international missions that are aimed at finding out habitable Earth-like planets is given. The educational opportunities and interdisciplinary unifying nature of astrobiology research are discussed. The paper concludes with an approach that can be adopted for coordinating the research in this new space science in a programmatic mode.

Molecular Simulations in Astrobiology  

NASA Technical Reports Server (NTRS)

One of the main goals of astrobiology is to understand the origin of cellular life. In the absence of any record of the earliest ancestors of contemporary cells, protocells, the most direct way to test our understanding of their characteristics is to construct laboratory models of protocells. Such efforts, currently underway in the NASA Astrobiology Program, are accompanied by computational studies aimed at explaining self-organization of simple molecules into ordered structures and developing designs of molecules that are capable of performing protocellular functions. Many of these functions, such as importing nutrients, capturing and storing energy, and responding to changes in the environment, are carried out by proteins bound to membranes. We use computer simulations to address the following, questions about these proteins: (1) How do small proteins (peptides) organize themselves into ordered structures at water-membrane interfaces and insert into membranes? (2) How do peptides aggregate to form membrane-spannin(y structures (e.g., channels)? (3) By what mechanisms do such aggregates perform their functions? The simulations are performed using the molecular dynamics (MD) method. In this method, Newton's equations of motion for each atom in the system are solved iteratively. At each time step, the forces exerted on each atom by the remaining atoms are evaluated by dividing them into two parts. Short-range forces are calculated directly in real space while long-range forces are evaluated in reciprocal space, usually using a particle-mesh algorithm which is of order O(NlnN). Currently, a time step of 2 femtoseconds is typically used, thereby making studies of problems occurring on multi-nanosecond time scales (10(exp 6) - 10(exp 8) time steps) accessible. To address a broader range of problems, simulations need to be extended by three orders of magnitude. Such an extension requires both algorithmic improvements and codes scalable to a large number of parallel processors. Work in this direction is in progress. Two specific series of simulations that demonstrate how peptides self-organize and function in membranes are discussed. In one series of simulations, it was shown that nonpolar peptides, disordered in water, translocate to the nonpolar interior of the membrane and, simultaneously, fold into two different helical structures, which remain in equilibrium. Once in the membrane, the peptides can readily change their orientation, especially in response to local electric fields. This structural and orientational flexibility of peptides with changing conditions may have provided a mechanism of transmitting signals between the environment and the interior of the protocell. In another series of simulations, the mechanism by which a simple protein channel efficiently mediates proton transport across membranes was investigated. This process is a key step in cellular bioenergetics. In the channel under study, proton transport is gated by four histidines that occlude the channel pore. The simulations demonstrate that protons move through the gate by a "shuttle" mechanism, wherein one histidine is protonated on the extracellular side and, subsequently, the proton bound on the opposite side is released.

Capturing Student Interest in Astrobiology through Dilemmas and Paradoxes  

NASA Astrophysics Data System (ADS)

Traditionally, many non-science majoring undergraduates readily reveal fairly negative opinions about their introductory science survey courses that serve as general education distribution requirements. Often seen as unimportant and unrelated to helping them acquire knowledge and skills for the workplace, such general education courses carry nicknames such as "Physics for Poets" (PHYSICS101), "Bugs for Thugs" (BIOLOGY101), "Rocks for Jocks" (GEOLOGY101), and "Moons for Goons" or "Scopes for Dopes" (ASTRONOMY101). In response, many faculty are experimenting with more modern science course offerings as general education courses in an effort to improve students' attitudes, values, and interests. One might think that ASTROBIOLOGY has natural curb appeal for students. However, despite the seemingly innate appeal of a course on extraterrestrial life, when it comes right down to it, an astrobiology course is still a natural science course at its core. As such, it can suffer from the same student apathy that afflicts traditional science courses if students can not find some personal relevance or interest in the topics. One approach to more fully engaging students is to couch core course concepts in terms of what Grant Wiggin and Jay McTighe (2004, 2000) call "essential questions." Essential questions are intended create enduring understanding in students and help students find deeply meaningful personal relevance to concepts. In response, we have created a series of probing essential questions that tie central concepts in astrobiology to dilemmas, paradoxes, and moral questions with the goal of intellectually engaging our students in the human-side of the astrobiology enterprise.

PREFACE: International Conference on High Pressure Science and Technology, Joint AIRAPT-22 & HPCJ-50  

NASA Astrophysics Data System (ADS)

The International Joint AIRAPT-22 & HPCJ-50 Conference was held in Odaiba, Tokyo, on 26-31 July 2009. About 480 scientists from 24 countries attended the conference and 464 papers, including 3 plenary lectures, 39 invited talks, and 156 oral presentations, were presented. It is my great pleasure to present this proceedings volume, which is based on the high quality scientific works presented at the conference. The International AIRAPT conference has been held every two years in various countries around the world since 1965, while High Pressure Conference of Japan (HPCJ) has been held annually since 1959 in various Japanese cities. Pressure is a fundamental parameter to control the property of matter. As a result, both AIRAPT and HPCJ have become highly multidisciplinary, and cover Physics, Chemistry, Materials Science, Earth and Planetary Sciences, Biosciences, Food Science, and Technology. Although each discipline has a unique target, they all have high-pressure research in common. This proceedings volume includes about 200 papers of state-of-the-art studies from numerous fields. I hope this proceedings volume provides excellent pieces of information in various fields to further advance high-pressure research.

Astrobiology: Study of the Living Universe  

NASA Technical Reports Server (NTRS)

Astrobiology is defined as the study of the living universe. This endeavor encompasses the use of space to understand life's origin, evolution, and destiny in the universe. Life's origin refers to understanding the origin of life in the context of the origin and diversity of planetary systems. Life's evolution refers to understanding how living systems have adapted to Earth's changing environment, to the all-pervasive force of gravity, and how they may adapt to environments beyond Earth. Life's destiny refers to making long-term human presence in space a reality, and laying the foundation for understanding and managing changes in Earth's environment. This lecture will explore the development of this field of inquiry, the science questions to be examined, and the mechanisms available for participation by the scientific community.

Critical issues in the history, philosophy, and sociology of astrobiology.  

PubMed

Fifty years after serious scientific research began in the field of exobiology, and forty years after serious historical research began on the subject of extraterrestrial life, this paper identifies and examines some of the most important issues in the history, philosophy, and sociology of what is today known as astrobiology. As in the philosophy of science in general, and in the philosophies of particular sciences, critical issues in the philosophy and sociology of astrobiology are both stimulated and illuminated by history. Among those issues are (1) epistemological issues such as the status of astrobiology as a science, the problematic nature of evidence and inference, and the limits of science; (2) metaphysical/scientific issues, including the question of defining the fundamental concepts of life, mind, intelligence, and culture in a universal context; the role of contingency and necessity in the origin of these fundamental phenomena; and whether or not the universe is in some sense fine-tuned for life and perhaps biocentric; (3) societal issues such as the theological, ethical, and worldview impacts of the discovery of microbial or intelligent life; and the question of whether the search for extraterrestrial life should be pursued at all, and with what precautions; and (4) issues related to the sociology of scientific knowledge, including the diverse attitudes and assumptions of different scientific communities and different cultures to the problem of life beyond Earth, the public "will to believe," and the formation of the discipline of astrobiology. All these overlapping issues are framed by the concept of cosmic evolution-the 13.7 billion year Master Narrative of the Universe-which may result in a physical, biological, or postbiological universe and determine the long-term destiny of humanity.

The set of habitable planets and astrobiological regulation mechanisms  

NASA Astrophysics Data System (ADS)

The number of habitable planets in the Milky Way and its temporal variation are major unknowns in the nascent fields of astrobiology and Search for ExtraTerrestrial Intelligence studies. All numerical models developed thus far have suffered from large uncertainties in the input data, in addition to our lack of understanding of the processes of astrobiological dynamics. Here, we argue that at least the input data can now be specified with more confidence, and use a simple Monte Carlo model of the Galactic Habitable Zone (GHZ) as a flexible platform for their elucidation. Previous papers have described some of the major results of this class of models; in this paper we present its mechanics and input parameters, notably the number of the habitable planets in the GHZ and their temporal distribution, based on the results of Lineweaver et al. (Lineweaver, C.H., Fenner, Y. & Gibson, B.K. (2004). Science 303, 59-62.) Regulation mechanisms (such as gamma-ray bursts or supernovae) and their temporal evolution, assumed to be main agents responsible for large-scale correlation effects, are modelled as type ? (which can sterilize part of or the entire GHZ) and type ? (which are of local importance) events with decreasing mean temporal frequency over the cosmological timescale. The considered global risk function implies as an upper limit that about one out of a hundred habitable sites will achieve high astrobiological complexity. The preliminary results of numerical modelling presented here and elsewhere imply that the lack of a sudden change from an essentially dead Galaxy to a Galaxy filled with complex life - the astrobiological phase transition - in our past (a version of Fermi's paradox) may be understood as a consequence of global astrobiological disequilibrium, strongly indicating such a transitional epoch in our future.

Undergraduate Research at SETI in Astrobiology  

NASA Astrophysics Data System (ADS)

The SETI Institute and San Jose State University (SJSU) have begun a partnership (URSA: Undergraduate Research at the SETI Institute in Astrobiology) in which undergraduate science and engineering majors from SJSU participate in research at the SETI Institute during the academic year. We are currently in our second year of the three-year NASA-funded grant. The goal of this program is to expose future scientists, engineers and educators to the science of astrobiology and to NASA in general, and by so doing, to prepare them for the transition to their future career in the Silicon Valley or beyond. The URSA students are mentored by a SETI Institute scientist who conducts research at the SETI Institute headquarters or nearby at NASA Ames Research Center. The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach. Its mission is to explore, understand and explain the origin, nature and prevalence of life in the universe. SJSU is a large urban public university that serves the greater Silicon Valley area in California. Students at SJSU come from diverse ethnic, cultural and socioeconomic backgrounds. Many of them face financial pressures that force them to pursue part-time work. URSA students are paid to work for 10 hours/week during the academic year, and also participate in monthly group meetings where they practice their presentation skills and discuss future plans. We encourage underserved and underrepresented students, including women, minority, and those who are the first in their family to go to college, to apply to the URSA program and provide ongoing mentoring and support as needed. While preparing students for graduate school is not a primary goal, some of our students have gone on to MS or PhD programs or plan to do so. The URSA program is funded by NASA EPOESS.

Astrobiological molecularly imprinted polymer sensors  

NASA Astrophysics Data System (ADS)

The purpose of the Astrobiological MIP Sensor (AMS) Project is to develop reliable, low-cost, low-mass, low-power consumption detection technologies for in situ analysis of biochemical markers, and other indicators of astrobiological importance. To this end, we are investigating the potential role that molecularly imprinted polymers (MIP) could serve in the recognition of pre-biotic and biotic compounds in planetary, astrobiological and geochemical mission profiles. While MIPs are effective molecular recognition tools, a signal transduction method must be developed so that the recognition of analytes can be realized. In the course of this study, surface plasmon resonance (SPR) will be the detection method of the MIP recognition event. In addition, MIP-coated SPR substrates were subjected to vibration, temperature and radiation testing to demonstrate that they could withstand the rigors of space travel. The methods developed in this study require capture of the biomarkers onto the SPR sensor chip, followed by addition of a MIP. It is the binding of the MIP to the SPR bound analyte that amplifies the SPR signal associated with binding of the low molecular weight analyte. The MIPs, developed in this study are water-soluble processable star polymers while the SPR device used was SensíQ™ by Nomatics. Proof-of-principal experiments were first demonstrated using amino biotin.

From 29–31 August 2013, the 1st International Conference on Light and Particle Beams in Materials Science, LPBMS 2013, took place in the Tsukuba International Congress Center in the city of Tsukuba, Japan. The conference was a continuation of the international series Synchrotron Radiation in Materials Science (SRMS), which started in 1994. The last one, SRMS-7, was held in Oxford UK 11–14 July 2010, where the International Advisory Committee (IAC) recommended the conference be enlarged to incorporate Materials Research from Neutron, Muon, and Slow Positron Sources, as well as the science emerging from Synchrotron Light Sources. The conference brought together contributions from academics and industrial researchers with a diverse background and experience from the physics, chemistry and engineering communities. The topics covered in the LPBMS2013 include strongly correlated electron systems, magnetism and magnetic materials, soft matter, interface and surface defects, catalysts, biomaterials, and ceramics. In the 3-day scientific program, the conference consisted of 9 plenary talks, 33 invited talks, 20 oral presentations, and 126 poster presentations. We are pleased to publish the proceedings of the LPBMS2013 in this volume of Journal of Physics: Conference Series. This volume contains 58 papers representing the work that was presented and discussed at the conference. We hope that this volume will promote further development of this interdisciplinary materials research emerging from synchrotron light, neutron, muon, and slow positron sciences.

Automated Aqueous Sample Concentration Methods for in situ Astrobiological Instrumentation  

NASA Astrophysics Data System (ADS)

The era of wet chemical experiments for in situ planetary science investigations is upon us, as evidenced by recent results from the surface of Mars by Phoenix’s microscopy, electrochemistry, and conductivity analyzer, MECA [1]. Studies suggest that traditional thermal volatilization methods for planetary science in situ investigations induce organic degradation during sample processing [2], an effect that is enhanced in the presence of oxidants [3]. Recent developments have trended towards adaptation of non-destructive aqueous extraction and analytical methods for future astrobiological instrumentation. Wet chemical extraction techniques under investigation include subcritical water extraction, SCWE [4], aqueous microwave assisted extraction, MAE, and organic solvent extraction [5]. Similarly, development of miniaturized analytical space flight instruments that require aqueous extracts include microfluidic capillary electrophoresis chips, ?CE [6], liquid-chromatography mass-spectrometrometers, LC-MS [7], and life marker chips, LMC [8]. If organics are present on the surface of Mars, they are expected to be present at extremely low concentrations (parts-per-billion), orders of magnitude below the sensitivities of most flight instrument technologies. Therefore, it becomes necessary to develop and integrate concentration mechanisms for in situ sample processing before delivery to analytical flight instrumentation. We present preliminary results of automated solid-phase-extraction (SPE) sample purification and concentration methods for the treatment of highly saline aqueous soil extracts. These methods take advantage of the affinity of low molecular weight organic compounds with natural and synthetic scavenger materials. These interactions allow for the separation of target organic analytes from unfavorable background species (i.e. salts) during inline treatment, and a clever method for selective desorption is utilized to obtain concentrated solutions on the order of 100?L from 1-10 mL of aqueous sample extract. The selective desorption process involves the derivatization of target analytes in the liquid state which acts to sequester these compounds by reducing their affinity towards the scavenger material. These processes show potential for a single step protocol for the purification of aqueous soil extracts and offer concentration factors of 10-100. These inline processing methods will help address problems of insufficient detection limits for organic detection on Mars and allow for integration as a module within future aqueous in situ flight instruments.

The only known chemical systems sophisticated enough to execute the functions of life are those made from carbon-based compounds. Saturn's moon Titan presents us with an extensive and rich inventory of complex organics, and is therefore of great astrobiological interest. Astrobiology at Titan has two principal facets. First is the prospect of an internal water ocean (like other icy satellites,

Systems astrobiology for a reliable biomarker on exo-worlds  

NASA Astrophysics Data System (ADS)

Although astrobiology is a science midway between biology and astrophysics, it has surprisingly remained largely disconnected from recent trends in certain branches of both of these disciplines. Aiming at discovering how systems properties emerge has proved valuable in chemistry and in biology and should also yield insights into astrobiology. This is feasible since new large data banks in the case of astrobiology are of a geophysical/astronomical kind, rather than the also large molecular biology data that are used for questions related firstly, to genetics in a systems context and secondly, to biochemistry. The application of systems biology is illustrated for our own planetary system, where 3 Earth-like planets are within the habitable zone of a G2V star and where the process of photosynthesis has led to a single oxygenic atmosphere that was triggered during the Great Oxidation Event some 2,5 billion years before the present. The significance of the biogenic origin of a considerable fraction of our atmosphere has been discussed earlier (Kiang et al., 2007). Bonding of O2 ensures that it is stable enough to accumulate in a world's atmosphere if triggered by a living process. The reduction of F and Cl deliver energy release per e+-transfer, but unlike O2 the weaker bonding properties inhibit large atmospheric accumulation (Catling et al., 2005). The evolution of O2-producing photosynthesis is very likely on exo-worlds (Wolstencroft and Raven, 2002). With our simplifying assumption of evolutionary convergence, we show how to probe for a reliable biomarker in the exo-atmospheres of planets, or their satellites, orbiting stars of different luminosities and ages (Chela-Flores, 2013). We treat the living process as a system of exo-environments capable of radically modifying their geology and atmospheres, both for exo-planets, and especially for exo-moons, the presence of which can be extracted from the Kepler data (Kipping et al., 2012). What we are learning about the moons of our solar system (Chela-Flores, 2010), and will learn in the foreseeable future with the JUICE Mission will be relevant to systems astrobiology. The distribution of systems of habitable worlds with their biomarkers will be testable in the short term with forthcoming space missions: FINNESSE, EChO and TESS. This would justify subsequent use of quantitative systems biology methods that are available from its repertoire of analytic approaches. References Catling et al. (2005).

Astrobiological benefits of human space exploration.  

PubMed

An ambitious program of human space exploration, such as that envisaged in the Global Exploration Strategy and considered in the Augustine Commission report, will help advance the core aims of astrobiology in multiple ways. In particular, a human exploration program will confer significant benefits in the following areas: (i) the exploitation of the lunar geological record to elucidate conditions on early Earth; (ii) the detailed study of near-Earth objects for clues relating to the formation of the Solar System; (iii) the search for evidence of past or present life on Mars; (iv) the provision of a heavy-lift launch capacity that will facilitate exploration of the outer Solar System; and (v) the construction and maintenance of sophisticated space-based astronomical tools for the study of extrasolar planetary systems. In all these areas a human presence in space, and especially on planetary surfaces, will yield a net scientific benefit over what can plausibly be achieved by autonomous robotic systems. A number of policy implications follow from these conclusions, which are also briefly considered. PMID:20735249

Report on the Conference on Science Perspectives for 3D Spectroscopy  

NASA Astrophysics Data System (ADS)

About four years ago when discussions were taking place to plan the proposal to the European Commission for a Research Training Network (RTN) on 3D spectroscopy, we decided to make an international conference one of the closing highpoints of the network. At that time there were only a few 3D instruments routinely taking data on large telescopes (such as Integral on the WHT and Oasis on the CFHT) and some of us thought that a full-scale international conference on science with 3D spectroscopy might be rather difficult to fill. However, as it transpired, we had problems containing the conference in four and a half days. The RTN, called Euro3D, shared the hosting of the conference with ESO and it was held at ESO Headquarters in Garching from October 10-14, 2005.

PREFACE: 23rd International Conference on High Pressure Science and Technology (AIRAPT-23)  

NASA Astrophysics Data System (ADS)

The 23rd AIRAPT International Conference on High Pressure Science and Technology was held at Bhabha Atomic Research Centre, Mumbai, from 25-30 September 2011. This conference is part of the series of AIRAPT International Conferences which are held biennially. AIRAPT is an acronym for the French title which translates as 'International Association for the Advancement of High Pressure Science and Technology'. This was the second time the AIRAPT Conference was organized in India. The first was held 20 years ago at the National Aeronautical Laboratory, Bangalore in 1991. The 23rd Conference covered many important topics in the area of both static and dynamic high pressures including theoretical and experimental investigations on the response of materials under high pressures, new developments using neutron and synchrotron sources, investigations on superconductivity under high pressure, studies of geophysical and planetary sciences, biosciences, and the synthesis of new materials. The conference program included Bridgman award lecture, Jemieson award lecture, seven plenary talks, 85 invited talks, 83 oral presentations and about 195 posters. In all there were 372 presentations. 285 scientists from 19 countries participated in the conference. The countries represented included Austria, Canada, China, Estonia, France, Germany, India, Israel, Italy, Japan, Nepal, New Zealand, Poland, Russia, South Korea, Spain, Sweden, Switzerland, Turkey, UK, Ukraine and USA. Many new developments were presented, for example, measurement techniques using the new generation synchrotron sources, more powerful neutron sources and much brighter laser sources; integration of gas-gun with synchrotron source; the achievement of multi-megabar pressures in shock-less dynamic compressions; and capabilities to synthesize centimeter size diamonds with better quality. All these developments have opened up new opportunities for understanding the physics of materials under high pressures. I would like to thank all those who have made valuable contributions to the success of the conference, which include the members of the AIRAPT executive committee, the International Advisory Committee and National Advisory Committee, the plenary speakers, invited speakers, the chairmen of various sessions, all the participants, and the authors of the papers in this volume. All the papers accepted for the proceedings have been reviewed by two independent referees. I am extremely thankful to all the anonymous referees, who have spent their valuable time to ensure the quality of the papers of this volume. I wish to express my gratitude to the members of the Local Organizing Committee for their help and hard work for the success of the conference. Finally, I convey my special thanks to Dr T C Kaushik and Dr K D Joshi, who worked tirelessly and enthusiastically towards making this conference a success. I am confident that this volume of the Conference proceedings will provide an excellent source of information on the current trends in the field of High Pressure Science and Technology.

Longitudinal effects of college type and selectivity on degrees conferred upon undergraduate females in physical science, life science, math and computer science, and social science  

NASA Astrophysics Data System (ADS)

There has been much research to suggest that a single-sex college experience for female undergraduate students can increase self-confidence and leadership ability during the college years and beyond. The results of previous studies also suggest that these students achieve in the workforce and enter graduate school at higher rates than their female peers graduating from coeducational institutions. However, some researchers have questioned these findings, suggesting that it is the selectivity level of the colleges rather than the comprised gender of the students that causes these differences. The purpose of this study was to justify the continuation of single-sex educational opportunities for females at the post-secondary level by examining the effects that college selectivity, college type, and time have on the rate of undergraduate females pursuing majors in non-traditional fields. The study examined the percentage of physical science, life science, math and computer science, and social science degrees conferred upon females graduating from women's colleges from 1985-2001, as compared to those at comparable coeducational colleges. Sampling for this study consisted of 42 liberal arts women's (n = 21) and coeducational (n = 21) colleges. Variables included the type of college, the selectivity level of the college, and the effect of time on the percentage of female graduates. Doubly multivariate repeated measures analysis of variance testing revealed significant main effects for college selectivity on social science graduates, and time on both life science and math and computer science graduates. Significant interaction was also found between the college type and time on social science graduates, as well as the college type, selectivity level, and time on math and computer science graduates. Implications of the results and suggestions for further research are discussed.

Taking the initiative: A leadership conference for women in science and engineering  

NASA Technical Reports Server (NTRS)

The conference sprang from discussions on the current climate that women face in science, mathematics, engineering, and technology. The conference (and this document) is a beginning, not a culmination, of women's learning leadership skills. Conferees were active, articulate, energetic, and ready to learn leadership qualities, some of which seem universal, others that appear to require skills in specific fields. After the introduction, the workshops and presentations are arranged under vision and direction, barriers, alignment and communication, and motivation and inspiration. Some statistics are presented on women degrees and employment in various fields.

The International Journal of Astrobiology  

NASA Astrophysics Data System (ADS)

The launch of a new journal is appropriately like a space mission. It is the result of a scientific need, the inspiration of a group of committed scientists and technologists, a series of draft proposals, an approved mission protocol, and a launch. Today is the launch day for a journal whose remit has only recently consolidated from diverse disciplines. Cambridge University Press has an international reputation for astronomy. To this we add extreme biology and its associated environmental research to integrate astrobiology as: 'the study of the origin, evolution, adaptation and distribution of past and present life in the Universe'. Astrobiology has three main themes: (1) Origin, evolution and limits of life on Earth; (2) Future of life, both on Earth and elsewhere; (3) Search for habitats, biomolecules and life in the Solar System and elsewhere. These fundamental concepts require the integration of various disciplines, including biology (especially microbiology), chemistry, geology, palaeontology, and the physics of atmospheres, planets and stars. We must also keep our minds wide open about the nature and limits of life. We can safely assume a carbon-based system within Solar Systems as we know them, but our concept of habitable zones expands yearly. We were taught that only the spores of certain bacilli could survive temperatures above the boiling point of water, and yet we now know that the deep-sea vent microbe Pyrolobus can survive an hour at 121 °C, which is the temperature used for sterilising medical instruments. We know of cyanobacteria which can not only live inside deep-frozen Antarctic rocks but also survive on roof-tops in Jerusalem at 80 °C. The bacterium Deinococcus radiodurans tolerates lethal doses of nuclear radiation, and cyanobacteria inside Antarctic desert sandstone receive so little moisture that their carbon turnover time (from its fixation by photosynthesis to its release as carbon dioxide during respiration) is 10,000 years. Life is tolerant, adaptable and tenacious.

Aspicilia fruticulosa: A new model for Astrobiology  

NASA Astrophysics Data System (ADS)

In order to avoid the technological constraints that prevent the performance of experiments in other planets, Astrobiology research implies the development of models that simulate the conditions present in outer space or in planetary bodies. Extremophile organisms, like lichens have been widely studied in Astrobiology due to their high resistance to extremely harsh envi-ronments(5). The vagrant lichen species, Aspicilia fruticulosa lives detached from the substrate, and has a coralloid thalli up to 2.5 cm, which provides a very compact internal structure(6). This species typically grows in deserts and arid areas. Its resistance has been tested several times and amazing results about their vitality have been obtained. Two main experiments have been per-formed: 1. LITHOPANSPERMIA experiment(1): Integrated on board of BIOPAN (multi-user exposure facility, designed for exobiology, radiation biology, radiation dosimetry and material science investigations in space (http://www.spaceflight.esa.int/users/index.cfm?act=default.pagelevel=11p foton-next-pay-Bpan) launched on the Foton M3 satellite in September 2007); the resistance of this lichen species to the combination of the following space conditions during 10 days was tested: Ultraviolet (UV) extraterrestrial radiation, Mars UV-climate, UV-B radiation and Photosynthetically Active Radiation (PAR), microgravity, space vacuum of 1x10-6 mbar and extreme temperatures ranging from -23o C to +16o C. After the flight, the samples were revital-ized for a 72h period in a climatic chamber before taking measurements of their photosynthetic activity with a Mini-PAM fluorometer (Heinz Walz GmbH) as described by R. de la Torre et al. 2007b (2). The results showed that the samples exposed to space environment except solar UV radiation, reached a 76.5-1002. A step further on these investigations was carried out in order to study how the viability of this lichen species were affected by a combination of different sim-ulated martian conditions. For this purpose, we used an environmental simulation chamber(4) placed at the CAB (Centro de Astrobiologé to reproduce martian conditions. Three different ?a) exposures, each of them during 80 hours, were performed: a) martian atmosphere (7mbar of atmospheric pressure, with a standard concentration of martian surface gases) and tempera-ture (-93o C); b) martian UV radiation (200-400nm), temperature(-93o C) and space vacuum (1x10-7 mbar); c) combination of martian UV radiation (200-400nm), atmosphere (7mbar of atmospheric pressure) and temperature (-93o C). A set of 8 samples were located on two levels: exposure level (L-1) and dark control level (L-2). A general tendence was observed: all the samples survived. The analysis of the results compared to the pre-simulation data showed: a) photosynthetic activity decreased (74 References: 1 R.

The AGU Chapman Conference on Communicating Climate Science: A Historic Look to the Future  

NASA Astrophysics Data System (ADS)

The American Geophysical Union hosted a Chapman Conference on Communicating Climate Science at Snow Mountain Ranch, Granby, Colorado, June 8-13, 2013. The goal of the Chapman Conference was to bring together scholars, social scientists and journalists to discuss the history, and more importantly, the present and future of climate change communication. We met to evaluate our current and needed communication capacity, and to develop ways and means to convey advances in the understanding of climate science. Delegates discussed and presented methods and capacity to communicate to policymakers, the media, and society. Our focus was on the efficacy of scientific communication, on improving communication practices, and on building collaborations spawned at the conference, and beyond. The Chapman was a success. Close to 150 of us gathered high in the Colorado Rockies to share almost 100 presentations and nearly 10 hours of group discussions focused on ways and means to better bring the climate change message to society, to educators and policymakers in North America and around the world. This presentation will focus on the outcomes of the Chapman Climate Change Communication Conference; the conclusions of the delegate community; and directions forward.

Heterocyclic Anions of Astrobiological Interest  

NASA Astrophysics Data System (ADS)

As more complex organic molecules are detected in the interstellar medium, the importance of heterocyclic molecules to astrobiology and the origin of life has become evident. 2-Aminothiazole and 2-aminooxazole have recently been suggested as important nucleotide precursors, highlighting azoles as potential prebiotic molecules. This study explores the gas-phase chemistry of three deprotonated azoles: oxazole, thiazole, and isothiazole. For the first time, their gas-phase acidities are experimentally determined with bracketing and H/D exchange techniques, and their reactivity is characterized with several detected interstellar neutral molecules (N2O, O2, CO, OCS, CO2, and SO2) and other reactive species (CS2, CH3Cl, (CH3)3CCl, and (CH3)3CBr). Rate constants and branching fractions for these reactions are experimentally measured using a modified commercial ion trap mass spectrometer whose kinetic data are in good accord with those of a flowing afterglow apparatus reported here. Last, we have examined the fragmentation patterns of these deprotonated azoles to elucidate their destruction mechanisms in high-energy environments. All experimental data are supported and complemented by electronic structure calculations at the B3LYP/6-311++G(d,p) and MP2(full)/aug-cc-pVDZ levels of theory.

PREFACE: Third Conference of the Asian Consortium for Computational Materials Science (ACCMS-3)  

NASA Astrophysics Data System (ADS)

Following the tradition of the ACCMS-1 held in Bangalore, India, in November 2001, and the ACCMS-2 in Novosibirsk, Russia, during July 14-16, 2004, this conference, held at the Institute of Physics, Chinese Academy of Sciences (CAS), Beijing, 8-11 September 2005, has been set up to promote research and development activities in computational materials science in Asian countries. Computational materials science has emerged as a distinct multidisciplinary branch of science whose relevance and importance has come from (a) the desire to have a microscopic understanding of complex materials and phenomena, (b) the need to design novel materials with a desired combination of physical, chemical and metallurgical properties, and (c) the possibility to describe the basic interatomic interactions in materials via appropriate quantum mechanical and statistical mechanical tools. With the unprecedented growth of computer power and the developments of efficient and smart algorithms and codes, it is now possible to do large scale simulations of real materials with increasing complexity. A synergy amongst a wide variety of disciplines such as physics, chemistry, metallurgy, geology, biology, computer science and information technology is gradually coming to a reality due to advances in computer simulations. What follows here are the written ACCMS-3 proceedings based on the presentations, oral and poster, of the research pursued by the various participating groups, which cover topics, such as density functional theory-based methods, Monte Carlo, molecular and lattice dynamics simulations, tight-binding and effective medium approaches, coarse graining and mesoscopic modeling, continuum and quasi-continuum approaches, etc and their applications to different materials. ACCMS-3 was chaired by Professor Enge Wang, and co-chaired by professors B.L. Gu, Y. Kawazoe and G.P. Das, and organized and supported by the Institute of Physics (Beijing), Chinese Academy of Sciences, and the Department of Physics, Tsinghua University. In addition, financial supports from Chinese Academy of Sciences and National Natural Science Foundation of China (NSFC) are gratefully acknowledged. The conference was held at the Institute of Physics, CAS, in its newly built conference hall. The excellent facilities and the competent support of the professional staff, headed by Dr Jian-tao Wang, created a genial environment for scientific discussion and exchange. Their invaluable assistance is also gratefully acknowledged.

Neocatastrophism and the Milky Way Astrobiological Landscape  

NASA Astrophysics Data System (ADS)

The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the effects of applying general neocatastrophic paradigm to the evolution of the Galactic Habitable Zone. In this paper, we investigate the limits of simple, 1-dimensional astrobiological models, and consider the role of regulation mechanisms in shapening the "astrobiological landscape". We show that the transition from predominantly gradualist to predominantly (neo)catastrophist history of our Galaxy leads to the build-up of large-scale correlations between habitable sites, offering possible keys to such important problems as Carter's "anthropic" argument and Fermi's paradox. In addition, we consider the possibilities for extending the present class of models into spatially realistic 3-dimensional case via probabilistic cellular automata.

Astrobiology Sample Analysis as a Design Driver  

NASA Technical Reports Server (NTRS)

This effort supports the Astrobiology Objective 8 the Search for LIFE ON MARS PAST AND PRESENT -(Astrobiology Program Office, 1998, p.7). The essential trade analysis is between returning very small samples to the Earth while protecting them versus in situ analysis on Mars. Developing these explicit parameters encompasses design, instrumentation, system integration, human factors and surface operations for both alternatives. This allocation of capability approach incorporates a "humans and machines in the loop" model that recognizes that every exploration system involves both humans and automated systems. The question is where in the loop they occur whether on Earth, in the Mars Base, in the rover or creeping over the Mars surface.

PREFACE: IC-MSQUARE 2012: International Conference on Mathematical Modelling in Physical Sciences  

NASA Astrophysics Data System (ADS)

The first International Conference on Mathematical Modelling in Physical Sciences (IC-MSQUARE) took place in Budapest, Hungary, from Monday 3 to Friday 7 September 2012. The conference was attended by more than 130 participants, and hosted about 290 oral, poster and virtual papers by more than 460 pre-registered authors. The first IC-MSQUARE consisted of different and diverging workshops and thus covered various research fields in which mathematical modelling is used, such as theoretical/mathematical physics, neutrino physics, non-integrable systems, dynamical systems, computational nanoscience, biological physics, computational biomechanics, complex networks, stochastic modelling, fractional statistics, DNA dynamics, and macroeconomics. The scientific program was rather heavy since after the Keynote and Invited Talks in the morning, two parallel sessions ran every day. However, according to all attendees, the program was excellent with a high level of talks and the scientific environment was fruitful; thus all attendees had a creative time. The mounting question is whether this occurred accidentally, or whether IC-MSQUARE is a necessity in the field of physical and mathematical modelling. For all of us working in the field, the existing and established conferences in this particular field suffer from two distinguished and recognized drawbacks: the first is the increasing orientation, while the second refers to the extreme specialization of the meetings. Therefore, a conference which aims to promote the knowledge and development of high-quality research in mathematical fields concerned with applications of other scientific fields as well as modern technological trends in physics, chemistry, biology, medicine, economics, sociology, environmental sciences etc., appears to be a necessity. This is the key role that IC-MSQUARE will play. We would like to thank the Keynote Speaker and the Invited Speakers for their significant contributions to IC-MSQUARE. We would also like to thank the members of the International Scientific Committee and the members of the Organizing Committee.

Astrobiology : is humankind ready for the next revolution ?  

NASA Astrophysics Data System (ADS)

The discovery of a first exoplanet, in 1995, did not revolutionize but knocked astronomical sciences over. At the same time, by opening new prospects of research, in particular in the search of planets similar to the Earth and in a possible extraterrestrial life, this discovery, since then abundantly repeated, gave a new breath to the public interest for this scientific field. But is humanity ready to learn the existence from extraterrestrial forms of life or to remain, in spite of its efforts, in ignorance? The question of the plurality of the worlds is one of the oldest interrogations conveyed by the human cultures, as testified by the multiple answers which were brought to it. In the same way, the concept of life is itself an inexhaustible source of philosophical and religious reflexions, with many consequences in moral domains. It is today necessary to accompany the scientific development in the field of astrobiology by attaching the greatest importance to this intellectual patrimony. It constitutes even one of the first stages of an ethical responsibility in astrobiology, as important as that concerning planetary protection.

A concept for NASA's Mars 2016 astrobiology field laboratory.  

PubMed

The Mars Program Plan includes an integrated and coordinated set of future candidate missions and investigations that meet fundamental science objectives of NASA and the Mars Exploration Program (MEP). At the time this paper was written, these possible future missions are planned in a manner consistent with a projected budget profile for the Mars Program in the next decade (2007-2016). As with all future missions, the funding profile depends on a number of factors that include the exact cost of each mission as well as potential changes to the overall NASA budget. In the current version of the Mars Program Plan, the Astrobiology Field Laboratory (AFL) exists as a candidate project to determine whether there were (or are) habitable zones and life, and how the development of these zones may be related to the overall evolution of the planet. The AFL concept is a surface exploration mission equipped with a major in situ laboratory capable of making significant advancements toward the Mars Program's life-related scientific goals and the overarching Vision for Space Exploration. We have developed several concepts for the AFL that fit within known budget and engineering constraints projected for the 2016 and 2018 Mars mission launch opportunities. The AFL mission architecture proposed here assumes maximum heritage from the 2009 Mars Science Laboratory (MSL). Candidate payload elements for this concept were identified from a set of recommendations put forth by the Astrobiology Field Laboratory Science Steering Group (AFL SSG) in 2004, for the express purpose of identifying overall rover mass and power requirements for such a mission. The conceptual payload includes a Precision Sample Handling and Processing System that would replace and augment the functionality and capabilities provided by the Sample Acquisition Sample Processing and Handling system that is currently part of the 2009 MSL platform.

Phenylketonuria Scientific Review Conference: state of the science and future research needs.  

PubMed

New developments in the treatment and management of phenylketonuria (PKU) as well as advances in molecular testing have emerged since the National Institutes of Health 2000 PKU Consensus Statement was released. An NIH State-of-the-Science Conference was convened in 2012 to address new findings, particularly the use of the medication sapropterin to treat some individuals with PKU, and to develop a research agenda. Prior to the 2012 conference, five working groups of experts and public members met over a 1-year period. The working groups addressed the following: long-term outcomes and management across the lifespan; PKU and pregnancy; diet control and management; pharmacologic interventions; and molecular testing, new technologies, and epidemiologic considerations. In a parallel and independent activity, an Evidence-based Practice Center supported by the Agency for Healthcare Research and Quality conducted a systematic review of adjuvant treatments for PKU; its conclusions were presented at the conference. The conference included the findings of the working groups, panel discussions from industry and international perspectives, and presentations on topics such as emerging treatments for PKU, transitioning to adult care, and the U.S. Food and Drug Administration regulatory perspective. Over 85 experts participated in the conference through information gathering and/or as presenters during the conference, and they reached several important conclusions. The most serious neurological impairments in PKU are preventable with current dietary treatment approaches. However, a variety of more subtle physical, cognitive, and behavioral consequences of even well-controlled PKU are now recognized. The best outcomes in maternal PKU occur when blood phenylalanine (Phe) concentrations are maintained between 120 and 360 ?mol/L before and during pregnancy. The dietary management treatment goal for individuals with PKU is a blood Phe concentration between 120 and 360 ?mol/L. The use of genotype information in the newborn period may yield valuable insights about the severity of the condition for infants diagnosed before maximal Phe levels are achieved. While emerging and established genotype-phenotype correlations may transform our understanding of PKU, establishing correlations with intellectual outcomes is more challenging. Regarding the use of sapropterin in PKU, there are significant gaps in predicting response to treatment; at least half of those with PKU will have either minimal or no response. A coordinated approach to PKU treatment improves long-term outcomes for those with PKU and facilitates the conduct of research to improve diagnosis and treatment. New drugs that are safe, efficacious, and impact a larger proportion of individuals with PKU are needed. However, it is imperative that treatment guidelines and the decision processes for determining access to treatments be tied to a solid evidence base with rigorous standards for robust and consistent data collection. The process that preceded the PKU State-of-the-Science Conference, the conference itself, and the identification of a research agenda have facilitated the development of clinical practice guidelines by professional organizations and serve as a model for other inborn errors of metabolism.

Role of the observer in the scientific process in astrobiology and in defining life  

NASA Astrophysics Data System (ADS)

The role of the observer in the scientific process has been studied in various contexts, including philosophical. It is notorious that the experiments are theory-loaded, that the observers pick and choose what they consider important based on their scientific and cultural backgrounds, and that the same phenomenon may be studied by different observers from different angles. In this paper we critically review various authors' views of the role of the observer in the scientific process, as they apply to astrobiology. Astrobiology is especially vulnerable to the role of the observer, since it is an interdisciplinary science. Thus, the backgrounds of the observers in the astrobiology field are even more heterogeneous than in the other sciences. The definition of life is also heavily influenced by the observer of life who injects his/her own prejudices in the process of observing and defining life. Such prejudices are often dictated by the state of science, instrumentation, and the science politics at the time, as well as the educational, scientific, cultural and other background of the observer.

The purpose of this conference is to enhance the professional development of graduate students and early postdoctoral researchers by providing an opportunity to present and discuss scientific research in an environment of their peers. For the first two years, LunGradCon has been held as a one-day conference in conjunction with the NASA Lunar Science Institue's (NLSI) Lunar Science Forum at the NASA Ames Research Center. Activities include an invited overview talk on each of the NASA Lunar Science Institute's three main research areas (OF the Moon, ON the Moon, and FROM the Moon), submitted oral presentations from graduate students and postdoctoral researchers, and networking opportunities with established member of the lunar science community and the NLSI. In each of the first two years of LunGradCon, there have been 20-25 attendees, with about 15 of those presenting submitted talks. Each speaker received feedback forms from the other participants in order to improve on their presentation techniques. Participants also provided feedback on the conference as a whole in order to evaluate the content and provide suggestions for improvement in following years. Overall, the feedback has been extremely positive. This talk will summarize the achievements of past LunGradCons and plans for expansion of the conference to ensure a long-term positive impact on the early careers of future lunar, planetary and space science researchers.

Miniature GC: Minicell ion mobility spectrometer (IMS) for astrobiology planetary missions  

NASA Technical Reports Server (NTRS)

Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or longer mission life for stationary landers/laboratories. We describe here the development of a miniature GC - Minicell Ion Mobility Spectrometer (IMS) under development through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA's Small Business Innovative Research (SBIR) Program.

From systems chemistry to systems astrobiology: life in the universe as an emergent phenomenon  

NASA Astrophysics Data System (ADS)

Although astrobiology is a science midway between the life and physical sciences, it has surprisingly remained largely disconnected from recent trends in certain branches of both life and physical sciences. We discuss potential applications to astrobiology of approaches that aim at integrating rather than reducing. Aiming at discovering how systems properties emerge has proved valuable in chemistry and in biology. The systems approach should also yield insights into astrobiology, especially concerning the ongoing search for alternative abodes for life. This is feasible since new data banks in the case of astrobiology - considered as a branch of biology - are of a geophysical/astronomical kind, rather than the molecular biology data that are used for questions related firstly, to genetics in a systems context and secondly, to biochemistry for solving fundamental problems, such as protein or proteome folding. By focusing on how systems properties emerge in astrobiology we consider the question: can life in the universe be interpreted as an emergent phenomenon? In the search for potential habitable worlds in our galactic sector with current space missions, extensive data banks of geophysical parameters of exoplanets are rapidly emerging. We suggest that it is timely to consider life in the universe as an emergent phenomenon that can be approached with methods beyond the science of chemical evolution - the backbone of previous research in questions related to the origin of life. The application of systems biology to incorporate the emergence of life in the universe is illustrated with a diagram for the familiar case of our own planetary system, where three Earth-like planets are within the habitable zone (HZ) of a G2 V (the complete terminology for the Sun in the Morgan-Keenan system) star. We underline the advantage of plotting the age of Earth-like planets against large atmospheric fraction of a biogenic gas, whenever such anomalous atmospheres are discovered in these worlds. A prediction is made as to the nature of the atmospheres of the planets that lie in the stellar HZs.

Deep Impact at Europa: A Hypervelocity Impact Mission for Astrobiology  

Microsoft Academic Search

Traditional applications of passive reflectance or emission spectroscopy are poorly suited for astrobiology of icy satellite surfaces, because ice is strongly absorbing and masks spectral regions where organics are active. Two recent Flagship missions, Galileo and Cassini, observed Europa with multiple instruments but failed to detect any organic molecules on its surface, highlighting the difficulty of conducting astrobiology from orbit.

Ethical issues in astrobiology: a Christian perspective (Invited)  

NASA Astrophysics Data System (ADS)

With its focus on the origin, extent, and future of life, Astrobiology raises exciting, multidisciplinary questions for science. At the same time, Astrobiology raises important questions for the humanities. For instance, the prospect of discovering extraterrestrial life - either intelligent or unintelligent - raises questions about humans’ place in the universe and our relationship with nature on planet Earth. Fundamentally, such questions are rooted in our understanding of what it means to be human. From a Christian perspective, the foundational claim about human nature is that all persons bear the "imago dei", the image of God. This concept forms the basis for how humans relate to one another (dignity) and how humans relate to nature (stewardship). For many Christians the "imago dei" also suggests that humans are at the center of the universe. The discovery of extraterrestrial life would be another scientific development - similar to evolution - that essentially de-centers humanity. For some Christian perspectives this de-centering may be problematic, but I will argue that the discovery of extraterrestrial life would actually offer a much needed theological corrective for contemporary Christians’ understanding of the "imago dei". I will make this argument by examining two clusters of ethical issues confronting Astrobiology: 1. What ethical obligations would human explorers owe to extraterrestrial life? Are there ethical obligations to protect extraterrestrial ecosystems from harm or exploitation by human explorers? Do our ethical considerations change, if the extraterrestrial life is a “second genesis;” in other words a form of life completely different and independent from the carbon-based life that we know on Earth? 2. Do we have an ethical obligation to promote life as much as we can? If human explorers discover extraterrestrial life and through examination determine that it is struggling to survive, do we have an ethical obligation to assist that ecological community to become stronger? If after a thorough investigation we determine that no life exists and that a planet is nothing more than a lifeless body of rocks and dust, do we have an ethical obligation to attempt the creation of life through a process called planetary ecosynthesis? Or, do we have the opposite obligation to respect the rocks and dust for what they are, and refrain from any attempts to engineer life on a lifeless planet? While these two clusters of issues pose new ethical questions, I will argue that from a Christian perspective the framework for responding to these challenges would remain the Genesis Creation stories and the concept of the "imago dei". However, the new ethical challenges posed by Astrobiology require a re-framing of the "imago dei" that is closer to the intent of the original scriptures and that predicts simultaneously the presence of extraterrestrial life and the de-centering of humanity.

Miniature GC-Minicell Ion Mobility Spectrometer (IMS) for In Situ Measurements in Astrobiology Planetary Missions

Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or ionger mission life for stationary landers/laboratories. The miniCometary Ice and Dust Experiment (miniCIDEX), which combined Gas Chromatography (GC) with helium Ion Mobility Spectrometry (IMS), was capable of providing the wide range of analytical information required for Astrobiology missions. The IMS used here was based on the PCP model 111 IMS. A similar system, the Titan Ice and Dust Experiment (TIDE), was proposed as part of the Titan Orbiter Aerorover Mission (TOAM). Newer GC systems employing Micro Electro- Mechanical System (MEMS) based technology have greatly reduced both the size and resource requirements for space GCs. These smaller GCs, as well as the continuing miniaturization of Astrobiology analytical instruments in general, has highlighted the need for smaller, dry helium IMS systems. We describe here the development of a miniature, MEMS GC-IMS system (MEMS GC developed by Thorleaf Research Inc.), employing the MiniCell Ion Mobility Spectrometer (IMS), from Ion Applications Inc., developed through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA s Small Business Innovative Research (SBIR) Program.

An Explorer-Class Astrobiology Mission  

NASA Technical Reports Server (NTRS)

In this paper we describe a potential new Explorer-class space mission, the AstroBiology Explorer (ABE), consisting of a relatively modest dedicated space observatory having a 50 cm aperture primary mirror which is passively cooled to T less than 65 K, resides in a low-background orbit (heliocentric orbit at 1 AU, Earth drift-away), and is equipped with a suite of three moderate order (m approx. 10) dispersive spectrographs equipped with first-order cross-dispersers in an "echellette" configuration and large format (1024xl024 pixel) near- and mid-IR detector arrays cooled by a modest amount of cryogen. Such a system would be capable of addressing outstanding problems in Astrochemistry and Astrophysics that are particularly relevant to Astrobiology and addressable via astronomical observation. The observational program of this mission would make fundamental scientific progress in each of the key areas of the cosmic history of molecular carbon, the distribution and chemistry of organic compounds in the diffuse and dense interstellar media, and the evolution of ices and organic matter in young planetary systems. ABE could make fundamental progress in all of these areas by conducting an approximately one year mission to obtain a coordinated set of infrared spectroscopic observations over the 2.5-20 micrometers spectral range at spectral resolutions of R greater than or equal to 1000 of approximately 1000 galaxies, stars, planetary nebulae, and young star planetary systems.

The Astrobiology Primer - an Early Career Scientist Education, Outreach and Professional Development Project  

NASA Astrophysics Data System (ADS)

We are early-career scientists jointly leading a project to write 'The Astrobiology Primer', a brief but comprehensive introduction to astrobiology, and we are using the process of producing the document as an innovative way of strengthening the international community of early-career astrobiologists. Astrobiology is the study of the origin, evolution, distribution and future of life in our universe. It includes not just study of life on Earth, but also the potential for life to exist beyond Earth, and the development of techniques to search for such life. It therefore incorporates geological and earth sciences, life sciences, chemistry, astronomy and planetary sciences. This requires astrobiologists to integrate these different disciplines in order to address questions such as 'How did Earth and its biosphere originate?', 'How do life and the physical, chemical and geological cycles on Earth interact, and affect each other?' and so 'What does life on Earth tell us about the habitability of environments outside Earth?'. The primer will provide a brief but comprehensive introduction to the field; it will be significantly more comprehensive than a normal review paper but much shorter than a textbook. This project is an initiative run entirely by early-career scientists, for the benefit of other early-career scientists and others. All the writers and editors of the primer are graduate/post-graduate students or post-doctoral fellows, and our primary target group for the primer is other early-career scientists, although we hope and expect that the primer will also be useful far more broadly in education and outreach work. An Astrobiology Primer was first published in 2006(Ref1), written and edited by a small group of early-career astrobiologists to provide an introduction to astrobiology for other early-career scientists new to the field. It has been used not only by the target group for private study, but in formal education and outreach settings at universities and high-schools. We are now producing a second edition, which is an entirely new re-write, and we are making the process of producing the primer a development opportunity in its own right, to strengthen the international community of early-career astrobiologists. We have recruited a large team of writers and editors, 45 people from 11 different countries across North and South America, Europe and Australia. By working together on this joint project we are strengthening links between early-career scientists in these countries. In addition, we have a wider group of early-career astrobiologists who we consulted on the content that the primer should include. We have also recruited early-career scientists from this group, and more widely, to act as 'accessibility reviewers' to check that the primer meets its goal of being clear to people who are not experts in the field. We expect that the primer will be published in 2012, in several different languages. It will be freely available online to all who want it. References 1.

Progress Toward an Enceladus Amino Acid Sampler Astrobiology Instrument  

NASA Astrophysics Data System (ADS)

The development of a new astrobiolgoy instrument for exploring the trace chemical composition of the Enceladus jets and plume, and the e-ring of Saturn is presented. The Enceladus amino acid sampler (EAAS) allows for detection of amino acids using optical Raman spectroscopy integrated with a sample pre-concentration system. The pre-concentration process facilitates the delivery of a sample to a mass spectrometer for detection of specific amino acids. The initial EAAS design utilizes lab-on-a-breadboard components where a sample inlet, sample outlet, reagents, controllers, pumps, valves and pre-concentration column for the EAAS prototype are all assembled on a 5" x 7" breadboard. The pre-concentration process is controlled using automation scripts and software. An optical window allows a Raman spectrometer to directly monitor the pre-concentration of amino acids in a filter/column loaded with of a strong cation exchange resin. Initial samples to demonstrate EAAS simulate the conditions of Don Juan Pond, one of the coldest and saltiest bodies of liquid water on Earth, located in the Wright Valley of Antarctica. This EAAS development is an important step toward a new type of astrobiology science instrument that is capable of operating on a spacecraft in flight or in orbit.

Habitability & Astrobiology Research in Mars Terrestrial Analogues  

NASA Astrophysics Data System (ADS)

We performed a series of field research campaigns (ILEWG EuroMoonMars) in the extreme Utah desert relevant to Mars environments, and in order to help in the interpretation of Mars missions measurements from orbit (MEX, MRO) or from the surface (MER, MSL), or Moon geochemistry (SMART-1, LRO). We shall give an update on the sample analysis in the context of habitability and astrobiology. Methods & Results: In the frame of ILEWG EuroMoonMars campaigns (2009 to 2013) we deployed at Mars Desert Research station, near Hanksville Utah, a suite of instruments and techniques [A, 1, 2, 9-11] including sample collection, context imaging from remote to local and microscale, drilling, spectrometers and life sensors. We analyzed how geological and geochemical evolution affected local parameters (mineralogy, organics content, environment variations) and the habitability and signature of organics and biota. Among the important findings are the diversity in the composition of soil samples even when collected in close proximity, the low abundances of detectable PAHs and amino acids and the presence of biota of all three domains of life with significant heterogeneity. An extraordinary variety of putative extremophiles was observed [3,4,9]. A dominant factor seems to be soil porosity and lower clay-sized particle content [6-8]. A protocol was developed for sterile sampling, contamination issues, and the diagnostics of biodiversity via PCR and DGGE analysis in soils and rocks samples [10, 11]. We compare the 2009 campaign results [1-9] to new measurements from 2010-2013 campaigns [10-12] relevant to: comparison between remote sensing and in-situ measurements; the study of minerals; the detection of organics and signs of life.

The Conference on Corporate Interference with Science and Health (the Conference) was held to examine this trend in three economically significant industries: fracking, food, and wireless. The Conference provided an overview of the structures of these three industries and the history of standard-setting therein, identified the sources of environmental exposures created by these industries, and surveyed the health consequences of these exposures and the policies that have resulted in them. It then examined corporate influence on the setting of these policies and the production of scientific studies and interpretation of their results. The Conference also analyzed the general influence of corporations on the political system and the relationship of this conflict of interest to the aforementioned topics. The concluding discussion focused on what solutions could be implemented to improve public health, including what institutional changes are necessary to promote public awareness and change policy.

Astrobiology and green chemistry: a new pedagogical connection  

NASA Astrophysics Data System (ADS)

Various pedagogical approaches are needed to introduce astrobiology into the chemistry curriculum. We are developing a new approach in which we connect green chemistry with astrobiology. Green chemistry is chemistry which is environmentally friendly. One obvious way for the organic chemistry to be environmentally friendly is to use water as solvent, instead of more toxic organic solvents. Another approach is to run so-called solventless reactions. For example, as the solid materials are mixed together, the melting point of the mixture is lower than the melting points of its individual components (the principle of the mixed-melting point). In some cases the entire mixture may melt upon mixing. The reactions would then occur in a viscous semi-solid state. An additional approach is to run the reactions by utilizing enzymes or man-made protein mimics as catalysts instead of toxic catalysts, such as those based on the transition metals. These and some other known examples of green chemistry have a great potential for astrobiology. The astrobiological reactions typically occur in water (e.g. prebiotic soup), in the solid mixtures (e.g. on the meteors), and may be catalyzed by various short peptides. The connection between the green chemistry principles and astrobiology represents a new pedagogical approach for infusion of astrobiology into the organic chemistry.

XVII International AIDS Conference: From Evidence to Action - Social, behavioural and economic science and policy and political science  

PubMed Central

AIDS 2008 firmly established stigma and discrimination as fundamental priorities in the push for universal access to HIV prevention, treatment, care and support. Conference sessions and discussions reinforced the tangible negative effects of stigma on national legislation and policies. A strong theme throughout the conference was the need to replace prevention interventions that focus exclusively on individual behaviour change or biomedical prevention interventions with "combination prevention" approaches that address both individual and structural factors that increase vulnerability to HIV infection. Several high-level sessions addressed various aspects of the debate over "vertical" (disease-specific) versus "horizontal" (health systems) funding. The majority of evidence presented at the conference suggests that HIV investments strengthen health systems through the establishment of clinical and laboratory infrastructure, strengthened supply and procurement systems, improvements in health care worker training, and increased community engagement. Human rights were a focal point at the conference; several presentations emphasized the importance of securing human rights to achieve universal access goals, including workplace discrimination, travel restrictions, gender inequality, and the criminalization of homosexuality, drug use, sex work, and HIV transmission and/or exposure.

Astrobiological and Geological Implications of Convective Transport in Icy Outer Planet Satellites  

NASA Technical Reports Server (NTRS)

The oceans of large icy outer planet satellites are prime targets in the search for extraterrestrial life in our solar system. The goal of our project has been to develop models of ice convection in order to understand convection as an astrobiologically relevant transport mechanism within icy satellites, especially Europa. These models provide valuable constraints on modes of surface deformation and thus the implications of satellite surface geology for astrobiology, and for planetary protection. Over the term of this project, significant progress has been made in three areas: (1) the initiation of convection in large icy satellites, which we find probably requires tidal heating; (2) the relationship of surface features on Europa to internal ice convection, including the likely role of low-melting-temperature impurities; and (3) the effectiveness of convection as an agent of icy satellite surface-ocean material exchange, which seems most plausible if tidal heating, compositional buoyancy, and solid-state convection work in combination. Descriptions of associated publications include: 3 published papers (including contributions to 1 review chapter), 1 manuscript in revision, 1 manuscript in preparation (currently being completed under separate funding), and 1 published popular article. A myriad of conference abstracts have also been published, and only those from the past year are listed.

Life Out There: An Astrobiological Multimedia Experience for the Digital Planetarium  

NASA Astrophysics Data System (ADS)

Planetariums have a long history of experimentation with audio and visuals to create new multimedia experiences. We report on a series of innovative experiences in the Gates Planetarium at the Denver Museum of Nature & Science in 2009-2011 combining live performances of music and navigation through scientific visualizations. The Life Out There productions featured a story showcasing astrobiology concepts at scales ranging from galactic to molecular, and told using VJ-ing of immersive visualizations and musical performances from the House Band to the Universe. Funded by the NASA Astrobiology Institute's JPL-Titan Team, these hour-long shows were broken into four separate themed musical movements, with an improvisatory mix of music, dome visuals, and spoken science narrative which resulted in no two performances being exactly alike. Post-performance dissemination is continuing via a recorded version of the performance available as a DVD and online streaming video. Written evaluations from visitors who were present at the live shows reveal high satisfaction, while one of the Life Out There concerts was used to inaugurate a new evening program to draw in a younger audience demographic to DMNS.

Contribution to a symbiogenic approach in astrobiology  

NASA Astrophysics Data System (ADS)

This article intends to continue our previous work on the symbiogenic approach to chemical and biological evolution. We believe that cooperative and synergistic processes were responsible, using terrestrial and extraterrestrial materials, for the creation of a large prebiotic pool, closely related to geochemical contexts, and intense interactions within. Probably, a series of synergistic and cooperative effects produced a wide source of creativity, and functional advantages that pushed the emergence of complex and functionally integrated biological systems, through the evolution of self-organization and auto-catalysis. It was only after this biochemical evolution of structures, which produced the informational capabilities necessary for self-replication, that the Darwinian mechanisms could arise. This way of perceiving the emergence of life follows the proposals regarding life's initial evolution in which the progenote proposed consisted in an open community of very diverse primitive cellular entities with intense symbiotic associations, antagonisms, and competition, and with a rapid and reticulate pattern of evolution. We believe this symbiogenic approach should be considered in the understanding of chemical and biological evolution. This discussion contributes to the development of astrobiological knowledge, since it gives other perspectives about life's appearance and development on Earth and elsewhere.

The mission of the U.S. Geological Survey (USGS) is to serve the Nation by providing reliable scientific information to describe and understand the earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life. As the Nation?s largest water, earth, and biological science and civilian mapping agency, the USGS can play a significant role in providing scientific knowledge and information that will improve our understanding of the relations of environment and wildlife to human health and disease. USGS human health-related research is unique in the Federal government because it brings together a broad spectrum of natural science expertise and information, including extensive data collection and monitoring on varied landscapes and ecosystems across the Nation. USGS can provide a great service to the public health community by synthesizing the scientific information and knowledge on our natural and living resources that influence human health, and by bringing this science to the public health community in a manner that is most useful. Partnerships with health scientists and managers are essential to the success of these efforts. USGS scientists already are working closely with the public health community to pursue rigorous inquiries into the connections between natural science and public health. Partnering agencies include the Armed Forces Institute of Pathology, Agency for Toxic Substances Disease Registry, Centers for Disease Control and Prevention, U.S. Environmental Protection Agency, Food and Drug Administration, Mine Safety and Health Administration, National Cancer Institute, National Institute of Allergy and Infectious Disease, National Institute of Environmental Health Sciences, National Institute for Occupational Safety and Health, U.S. Public Health Service, and the U.S. Army Medical Research Institute of Infectious Diseases. Collaborations between public health scientists and earth scientists can lead to improved solutions for existing and emerging environmental health problems. This report summarizes the presentations and discussions held at the Second National Conference on USGS Health-Related Research, held at the USGS national headquarters in Reston, Virginia. The report presents 68 abstracts of technical presentations made at the conference and summaries of six topical breakout sessions. The abstracts cover a broad range of issues and demonstrate connections between human health and the quality and condition of our environment and wildlife. The summaries of the topical breakout sessions present ideas for advancing interdisciplinary science in areas of earth science and human health.

Investigating the state of the Sun-Earth system during extreme events: First science results of a worldwide online conference series  

NASA Astrophysics Data System (ADS)

This presentation reports on new science results from an online conference entitled "Return to the Auroral Oval for the Anniversary of the IGY" designed to bring together researchers worldwide: (1) to investigate newly reported features in the auroral oval during substorms that occur in the main phase of superstorms and how these features map throughout geospace, (2) to explore implications for the state of the geospace system, (3) to identify signatures associated with this geospace state from equatorial to polar latitudes, (4) to investigate the unusual aspects of the solar sources, and (5) to understand how propagation from Sun to Earth modified the observed solar drivers. The main focus of the first conference is on worldwide data exchange, the construction of global data products and assimilative global views, and identifying coupled chains of events from sun-to-Earth. The collaborative conference data products and enhanced understanding of the observed features of the events will form the basis for a follow-on conference in 2007 focused primarily on theoretical studies and collaborative simulation efforts between modeling groups, observers and data analysts. This conference is the first in a series of sun-Earth connection online conferences, sponsored by CAWSES, IHY, eGY, ICESTAR, NASA/LWS, and NSF Atmospheric Science Programs, and designed to bring interdisciplinary researchers together with the vast developing cyber-infrastructure of large international data sets, high performance computing and advanced visualizations to address grand challenge science issues in a way not previously possible.

Too early? On the apparent conflict of astrobiology and cosmology  

NASA Astrophysics Data System (ADS)

An interesting consequence of the modern cosmological paradigm is the spatial infinity of the universe. When coupled with naturalistic understanding of the origin of life and intelligence, which follows the basic tenets of astrobiology, and with some fairly incontroversial assumptions in the theory of observation selection effects, this infinity leads, as Ken Olum has recently shown, to a paradoxical conclusion. Olum's paradox is related, to the famous Fermi's paradox in astrobiology and SETI studies. We, hereby, present an evolutionary argument countering the apparent inconsistency, and show how, in the framework of a simplified model, deeper picture of the coupling between histories of intelligent/technological civilizations and astrophysical evolution of the Galaxy, can be achieved. This strategy has consequences of importance for both astrobiological studies and philosophy.

Astrobiological Implications of Rock Varnish in Tibet  

NASA Astrophysics Data System (ADS)

The study of terrestrial geomicrobiology and its relationship to rock weathering processes is an essential tool in developing analogues for similar processes that may have occurred on Mars. Most studies of manganese-enhanced rock varnish have focused on samples taken from warm arid desert regions. Here, we examine samples obtained from eolian-abraded lava flows of the 4700-4800 m high Ashikule Basin in Tibet. Because it receives approximately 300 mm of precipitation annually, this site is nowhere near as dry as Atacama Desert locales. However, the dusty, sulfate-rich, high-altitude and high-UV flux environment of the Tibetan locale offers new insight into rock varnish formation processes in a terrestrial environment that displays some attributes similar to those expected on early Mars. Microprobe measurements reveal that Mn enhancements in varnish are two orders of magnitude above the dust source, but Fe is only enhanced by a factor of three. Manganese-enhancing bacterial forms are not abundant but are still approximately 3 times more common than in Mojave and Sonoran Desert varnishes. In addition to its occurrence in subaerial positions, Tibetan varnish also occurs in micron-scale "pods" enveloped by silica glaze and as remobilized constituents that have migrated into the underlying weathering rind. A lack of surficial Mn-rich varnish, therefore, might not imply the absence of varnish. In contrast to suggestions that silica glaze might be a good source of microbial fossils and a key to varnish formation, we did not observe any clear microfossil forms entombed in silica glaze; further, there is no gradation between varnish and silica glaze but only distinct contacts. %K Analogue, Astrobiology, Bacteria, Biomineralization, Desert varnish, Geomicrobiology, Life on Mars, Manganese enhancement, Rock coating, Rock varnish, Microstromatolite, Tibet, Weathering

The Aouda.X space suit simulator and its applications to astrobiology.  

PubMed

We have developed the space suit simulator Aouda.X, which is capable of reproducing the physical and sensory limitations a flight-worthy suit would have on Mars. Based upon a Hard-Upper-Torso design, it has an advanced human-machine interface and a sensory network connected to an On-Board Data Handling system to increase the situational awareness in the field. Although the suit simulator is not pressurized, the physical forces that lead to a reduced working envelope and physical performance are reproduced with a calibrated exoskeleton. This allows us to simulate various pressure regimes from 0.3-1 bar. Aouda.X has been tested in several laboratory and field settings, including sterile sampling at 2800 m altitude inside a glacial ice cave and a cryochamber at -110°C, and subsurface tests in connection with geophysical instrumentation relevant to astrobiology, including ground-penetrating radar, geoacoustics, and drilling. The communication subsystem allows for a direct interaction with remote science teams via telemetry from a mission control center. Aouda.X as such is a versatile experimental platform for studying Mars exploration activities in a high-fidelity Mars analog environment with a focus on astrobiology and operations research that has been optimized to reduce the amount of biological cross contamination. We report on the performance envelope of the Aouda.X system and its operational limitations. PMID:22300413

PREFACE: Selected papers from the Fourth Topical Conference on Nanoscale Science and Engineering of the American Institute of Chemical Engineers  

NASA Astrophysics Data System (ADS)

This special issue of Nanotechnology contains research papers contributed by the participants of the Fourth Topical Conference on Nanoscale Science and Engineering at the Annual Meeting of the American Institute of Chemical Engineers (AIChE), which was held in Austin, Texas, USA, 7-12 November, 2004. This conference saw 284 oral presentations from institutions around the world, which is the highest number for this topical conference series to date. These presentations were organized into 64 sessions, covering the range of nanotechnology subject areas in which chemical engineers are currently engaged. These sessions included the following areas. ? Fundamentals: thermodynamics at the nanoscale; applications of nanostructured fluids; transport properties in nanophase and nanoscale systems; molecular modelling methods; self and directed assembly at the nanoscale; nanofabrication and nanoscale processing; manipulation of nanophases by external fields; nanoscale systems; adsorption and transport in carbon nanotubes; nanotribology; making the transition from materials and phenomena to new technologies; operation of micro-and nano-systems. ? Materials: nanoparticle synthesis and stabilization; nanoscale structure in polymers; nanotemplating of polymers; synthesis of carbon nanotubes and nanotube-based materials; nanowires; nanoparticle assemblies and superlattices; nanoelectronic materials; self-assembly of templated inorganic materials; nanostructured hybrid organic/inorganic materials; gas phase synthesis of nanoparticles; multicomponent structured particles; nano energetic materials; liquid-phase synthesis of nanoparticles. ? Energy: synthesis and characterization of nanostructured catalytic materials; nanomaterials and devices for energy applications. ? Biotechnology: nanobiotechnology; nanotechnology for the biotechnology and pharmaceuticals industries; nanotechnology and nanobiotechnology for sensors; advances in biomaterials, bionanotechnology, biomimetic systems and tissue engineering; nanotechnology for drug delivery and imaging; bionanotechnology in cancer and cardiovascular disease; nanostructured biomaterials; nanotechnology in bioengineering; nanofabrication of biosensing devices. We are pleased to present a selection of research papers in this special issue of Nanotechnology on behalf of the Nanoscale Science and Engineering Forum (NSEF). NSEF was established in 2001 as a new division of AIChE to promote nanotechnology efforts in chemical engineering. The chemical engineering discipline deals with the production and processing of chemicals and materials, and does so through a fundamental understanding of the core issues of transport, thermodynamics, and kinetics that exist at multiple length scales. Thus, it should come as no surprise that chemical engineers have been pursuing nanotechnology research for the last fifty years. For example, fuel production has benefited immensely from improved catalysts in which their pore structure is controlled with nanoscale precision, and polymer properties have been improved by controlling the polymer supramolecular structure at the nanometre scale. Chemical engineering will continue to make important contributions to nanotechnology, and will play a critical role in the transition from basic science and engineering research to commercial applications. We would like to thank all of the authors who contributed to this special issue; the three NSEF poster presentation award winners for their papers (Sureshkumar, Sunkara, and Rinaldi groups); Dr Nina Couzin, Publisher of Nanotechnology, for her support and enthusiasm for this project; Drs Sharon Glotzer and Dan Coy who chaired the topical conference; and Drs Meyya Meyyappan and Brett Cruden (NASA Ames Research Center) for their assistance in the initial planning stages.

Too early? On the apparent conflict of astrobiology and cosmology  

Microsoft Academic Search

An interesting consequence of the modern cosmological paradigm is the spatial infinity of the universe. When coupled with naturalistic understanding of the origin of life and intelligence, which follows the basic tenets of astrobiology, and with some fairly incontroversial assumptions in the theory of observation selection effects, this infinity leads, as Ken Olum has recently shown, to a paradoxical conclusion.

Astrobiological studies with extremely halophilic Archaea  

NASA Astrophysics Data System (ADS)

Extremely halophilic Archaea were isolated and characterized by both classical and modern molecular biological methods from hypersaline and haloalkaline lakes, salted soils, solar salterns and rock salt deposits (1). The survival of these micro-organisms after embedding in laboratory-made halite was investigated. Their presence in fluid inclusions was demonstrated by staining with the BacLight LIVE/DEAD kit and observation of their fluorescence by microscopy. Following resuspension of cells from halite crystals, a survival of about 0.5 - 4% according to colony forming units was obtained. In previous studies which focussed on the resistance of halophilic archaea to UV radiation or the space environment, survival of a dose of 110 J/m2 (using liquid cultures) and up to 10 000 J/m2 at a range of 200 - 400 nm was reported, when dried Haloarcula sp. in a single layer were exposed on the Biopan facility (2). We exposed a few haloarchaeal strains to a Martian UV simulator lamp with a range of 200 - 400 nm and an intensity of 41.2 W/m2, obtaining a viability of about 51- 67% of cells following different exposure times. Other studies focus on the detection of haloarchaea in halite by Raman microspectroscopy and by NIR-FT-Raman spectroscopy, which are considered to be important future tools for Mars exploration (3). Using the Dilor XY Raman spectrometer with laser excitation at 514.5 nm, equipped with a confocal microscope BX40 (Olympus Corp., Japan) and a Bruker IFS 66 + FRA106 with laser excitation at 1064 nm (Bruker, Germany), instruments, we obtained characteristic carotenoid peaks contained by these microorganisms. 1.

MST 1: Proceedings of a conference on the integration of mathematics, science and technology in precollege education  

SciTech Connect

Example MST activities examined here show: (1) an inquiry-driven learning stimulus, involving (2) the synthesis of concepts in math, science and technology, through (3) the application of the scientific method and engineering problem solving/test protocols, and provoking (4) a stimulus for further exploration. A semi-exploratory learning approach offered background aimed at enabling participants to take meaningful courses of investigation; this approach must be balanced by maintaining contact with framework content standards. On the whole, the philosophy underlying the MST learning approach--as envisioned in the draft NYS Framework, and embodied in the example activities--is strongly endorsed. This endorsement is broad-based: those represented include teachers of mathematics, science, and technology, and school district administrators--in roughly equal numbers. Discussion centers not on whether the MST approach should be pursued, but on what is involved in doing it. Teams of conference participants were given time to plan or extend MST initiatives in their own districts. Outlines of the initiatives proposed by ten of the teams are disseminated herein.

Landing on the Moon's farside: What are the geochemistry, astrobiology and instrumental issues?  

NASA Astrophysics Data System (ADS)

A high research priority in astrobiology is the search and eventual identification of biomarkers in the Solar System with feasible instrumentation. In spite of numerous steps forward lunar science remains largely disjoint from the main stream of astrobiology. In recent years the Moon has begun to emerge as a novel target for astrobiologists (Crawford et al., 2010). We discuss an overlap between lunar geochemistry and terrestrial geomicrobiology arising from the analysis of lunar soils and some uncertainties in chemical evolution and the origin of life scenarios (Chela-Flores, 2011). Unexpected isotopic heterogeneity of nitrogen was found to be remarkable in samples from Apollo and the Luna programme (Kerridge, 1975). Both the stable isotope geochemical data of the biogenic elements, as well as the noble gases trapped in lunar soils have added valuable new and relevant data. These discoveries are potential sources of information on early biological evolution on Earth. The elusive ratio of nitrogen's two stable isotopes 15N/14N has played a fundamental role in this aspect of lunar geochemistry (Owen et al., 2001). The analysis of individual grains of ilmenite suggests that 90% of all the trapped nitrogen does not originate from solar wind. We discuss the significance of these stable isotopes from the point of view of astrobiology in the light of the next generation of lunar exploration. We underline the high priority of testing the origin of non-solar nitrogen source trapped in the regolith of the lunar farside. In current proposals of new lunar missions, the characterisation of the geochemistry at several lunar sites is a major objective (Smith et al., 2011). Some arguments are presented in favor of using novel space technologies in a search for biomarkers in geographical distinct lunar landing sites. We restrict our attention to one aspect of the science requirements for the forthcoming missions by focusing on a very limited objective: to take a closer look at the geochemical characterisation of the chemical element nitrogen on the soils of the lunar farside and the related payload issues.

Astrobiological Aspects of Mars and Human Presence: Pros and Cons  

PubMed Central

After the realization of the International Space Station, human exploratory missions to Moon or Mars, i.e. beyond low Earth orbit, are widely considered as the next logical step of peaceful cooperation in space on a global scale. Besides the human desire to extend the window of habitability, human exploratory missions are driven by several aspects of science, technology, culture and economy. Mars is currently considered as a major target in the search for life beyond the Earth. Understanding the history of water on Mars appears to be one of the clues to the puzzle on the probability of life on Mars. On Earth microorganisms have flourished for more than 3.5 Ga and have developed strategies to cope with so-called extreme conditions (e.g., hot vents, permafrost, subsurface regions, rocks or salt crystals). Therefore, in search for life on Mars, microorganisms are the most likely candidates for a putative biota on Mars and the search for morphological or chemical signatures of life or its relics is one of the primary and most exciting goals of Mars exploration. The presence of humans on the surface of Mars will substantially increase this research potential, e.g., by supporting deep subsurface drilling and by allowing intellectual collection and sophisticated in situ analysis of samples of astrobiological interest. On the other hand, such long-duration missions beyond LEO will add a new dimension to human space flight, concerning the distance of travel, the radiation environment, the gravity levels, the duration of the mission, and the level of confinement and isolation the crew will be exposed to. This will raise the significance of several health issues, above all radiation protection, gravity related effects as well as psychological issues. Furthermore, the import of internal and external microorganisms inevitably accompanying any human mission to Mars, or brought purposely to Mars as part of a bioregenerative life support system needs careful consideration with regard to planetary protection issues. Therefore, before planning any human exploratory mission, the critical issues concerning human health and wellbeing as well as protection of Mars in its pristine condition need to be investigated.

Extremotolerance and resistance of lichens: comparative studies on five species used in astrobiological research I. Morphological and anatomical characteristics.  

PubMed

Lichens are symbioses of two organisms, a fungal mycobiont and a photoautotrophic photobiont. In nature, many lichens tolerate extreme environmental conditions and thus became valuable models in astrobiological research to fathom biological resistance towards non-terrestrial conditions; including space exposure, hypervelocity impact simulations as well as space and Martian parameter simulations. All studies demonstrated the high resistance towards non-terrestrial abiotic factors of selected extremotolerant lichens. Besides other adaptations, this study focuses on the morphological and anatomical traits by comparing five lichen species-Circinaria gyrosa, Rhizocarpon geographicum, Xanthoria elegans, Buellia frigida, Pleopsidium chlorophanum-used in present-day astrobiological research. Detailed investigation of thallus organization by microscopy methods allows to study the effect of morphology on lichen resistance and forms a basis for interpreting data of recent and future experiments. All investigated lichens reveal a common heteromerous thallus structure but diverging sets of morphological-anatomical traits, as intra-/extra-thalline mucilage matrices, cortices, algal arrangements, and hyphal strands. In B. frigida, R. geographicum, and X. elegans the combination of pigmented cortex, algal arrangement, and mucilage seems to enhance resistance, while subcortex and algal clustering seem to be crucial in C. gyrosa, as well as pigmented cortices and basal thallus protrusions in P. chlorophanum. Thus, generalizations on morphologically conferred resistance have to be avoided. Such differences might reflect the diverging evolutionary histories and are advantageous by adapting lichens to prevalent abiotic stressors. The peculiar lichen morphology demonstrates its remarkable stake in resisting extreme terrestrial conditions and may explain the high resistance of lichens found in astrobiological research.

Developing cyber-infrastructure for addressing grand challenge questions in Sun-Earth system science: First results of a testbed worldwide online conference series  

NASA Astrophysics Data System (ADS)

Software supporting an online conference series was developed with the purpose of catalyzing interdisciplinary investigations in Sun-Earth system science among large groups of researchers worldwide in celebration of the 50th anniversary of the International Geophysical Year in 2007. Transformative science in this area lies at the edges and intersections of individual elements (the Sun, heliosphere, magnetosphere, ionosphere and atmosphere) whose collective behavior determines the global system response. Continuing progress requires access to a vast developing cyber-infrastructure of large international data sets, high performance computing and advanced visualization. However, it also requires the development of new tools that bring these advances into contact with groups of interdisciplinary and international researchers so they can be used to attack grand challenge science issues in a manner not previously possible. This presentation describes the results of an eGY showcase project to develop a testbed online conference series for this purpose. The conference series is a collaborative effort between the CAWSES, IHY, eGY, ICESTAR, NASA/LWS and NSF Atmospheric Sciences Programs. Lessons learned in developing this first interface, as well as a discussion of key elements and how they worked will be presented.

Space Environment Survivability of Live Organisms: Results From a NASA Astrobiology Nanosatellite Mission  

NASA Astrophysics Data System (ADS)

NASA's Organism/Organic Exposure to Orbital Stresses, or O/OREOS, nanosatellite is a sci-ence demonstration mission that showcases achievements in using hardware from a technology development program led by the Small Spacecraft Division at NASA's Ames Research Center, Moffett Field, California. Continuing Ames' development of triple-cube nanosatellite tech-nology and flight systems, which includes the successful GeneSat-1 and PharmaSat missions, O/OREOS is constructed from off-the-shelf commercial and NASA-designed parts to create a fully self-contained, automated, stable, light-weight space science laboratory with innovative environment and power control techniques; sensors to monitor the levels of pressure, temper-ature, humidity, radiation and acceleration; and a communications system able to regularly accept commands from the ground and transmit data back to Earth for scientific analysis. The overall goal of the O/OREOS mission is to demonstrate the capability to do low-cost sci-ence experiments on autonomous nanosatellites in space in support of the Astrobiology Small Payloads program under the Planetary Science Division of the Science Mission Directorate at NASA Headquarters. The spacecraft houses two science payloads: the Space Environment Viability of Organics (SEVO) experiment will monitor the stability and changes in four classes of organic matter (results presented at another COSPAR session); and the Space Environment Survivability of Live Organisms (SESLO) experiment (presented here). SESLO will charac-terize the growth, activity, health, and ability of microorganisms to adapt to the stresses of the space environment. The experiment is sealed in a vessel at one atmosphere and contains two types of microbes commonly found in salt ponds and soil, in a dried and dormant state: Halorubrum chaoviator and Bacillus subtilis. After it reaches orbit, the experiment will initiate and begin to rehydrate and grow three sets of the microbes at three different times: a few days, three months, and six months after launch. Once the satellite is in its highly inclined orbit, the microbes are constantly being exposed to space's high-energy radiation while in micro-gravity. The SESLO experiment measures the microbes' population density as they consume the components of the nutrient medium; a metabolism indicator dye included in the medium changes color, enabling quantitative tracking of metabolic activity. Together, these data en-able determination of the effects of the combined exposure to space radiation and microgravity on organism growth, health and survival. The design of the spacecraft, its ability to support Astrobiology goals, and the actual spaceflight data obtained will be presented.

Astrobiology is a transdisciplinary field with extraordinary potential for the scientific community. As such, it is important to educate the community at large about the growing importance of this field to increase awareness and scientific content learning and expose potential future scientists. To this end, we propose the creation of a traveling museum exhibit that focuses exclusively on astrobiology and utilizes modern museum exhibit technology and design. This exhibit (the "Astrobiology Road Show"), organized and evaluated by an international group of astrobiology students and postdocs, is planned to tour throughout the Americas. PMID:23469863

Case studies approach for an undergraduate astrobiology course  

NASA Astrophysics Data System (ADS)

Case studies is a well known and widely used method in law schools, medical schools, and business schools, but relatively little used in physics or astronomy courses. We developed an astrobiology course based strongly on the case studies approach, and after teaching it first at the University of Alabama in Huntsville, we have adapted it and are now teaching it at Alabama A&M University, a HBCU. The case studies approach uses several well tested and successful teaching methods - including group work, peer instruction, current interest topics, just-in-time teaching, &c. We have found that certain styles of cases are more popular among students than other styles, and will revise our cases to reflect such student preferences. We chose astrobiology -- an inherently multidisciplinary field -- because of the popularity of the subject matter, its frequent appearance in the popular media (news stories about searches for life in the universe, the discovery of Earth-like exoplanets, etc, in addition to SciFi movies and novels), and the rapid current progress in the field. In this talk we review briefly the case studies method, the styles of cases used in our astrobiology course, and student response to the course as found in our assessment analysis.

This collaborative opportunity for multi-disciplinary GIS and associated professionals will allow attendees to present and discuss a wide variety of geospatial-related topics. The Users Conference and Workshop collaboration will bring together scientists, managers, and data users who, through presentations, posters, seminars, workshops, and informal gatherings, will share accomplishments and progress on a variety of geospatial topics. During this joint event, attendees will have the opportunity to present or demonstrate their work; to develop their knowledge by attending hands-on workshops, seminars, and presentations given by professionals from USGS and other Federal Agencies, GIS related companies, and academia; and to network with other professionals to develop collaborative opportunities. Specific conference topics include scientific and modeling applications using The National Map, opportunities for partnerships, and advances in geospatial technologies. The first part of the week will be the GIS Workshop, offered as a pre-conference seminar. It will focus on hands-on GIS training and seminars concerning current topics of geospatial interest. The focus of the USGS GIS Workshop is to showcase specific techniques and concepts for using GIS in support of science. The presentations will be educational and not a marketing endeavor. To promote awareness of and interaction with selected USGS corporate and local science center data products, as well as promoting collaboration, a “GIS Olympics” event will be held Tuesday evening during the GIS Workshop. The second part of the week will feature interactive briefings and discussions on issues and opportunities of The National Map. The focus of the Users Conference will be on the role of The National Map in supporting science initiatives, emergency response, land and wildlife management, and other activities. All presentations at the Users Conference include use or innovations related to a The National Map data theme or application. On Wednesday evening, a poster session is being held as a combined event for all attendees and as a juncture between the events. On Thursday evening, the Henry Gannett Award will be presented. Additionally, poster awards will be presented. Several prominent speakers are featured at plenary sessions at The National Map Users Conference, including Deanna A. Archuleta, Deputy Assistant Secretary for Water and Science, Department of the Interior; Dr. Barbara P. Buttenfield, Professor of Geography at the University of Colorado in Boulder; best-selling author Frederick Reuss; and Dr. Joel Scheraga, Senior Advisor for Climate Adaptation, U.S. Environmental Protection Agency.

The AstroBiology Explorer (ABE) MIDEX Mission Concept: Using Infrared Spectroscopy to Identify Organic Molecules in Space  

NASA Technical Reports Server (NTRS)

One of the principal means by which organic compounds are detected and identified in space is by infrared spectroscopy. Past IR telescopic and laboratory studies have shown that much of the carbon in the interstellar medium (ISM) is in complex organic species but the distribution, abundance and evolutionary relationships of these materials are not well understood. The Astrobiology Explorer (ABE) is a MIDEX mission concept designed to conduct IR spectroscopic observations to detect and identify these materials and address outstanding problems in astrobiology, astrochemistry, and astrophysics. ABE's core science program includes observations of planetary nebulae and stellar outflows, protostellar objects, Solar System objects, and galaxies, and lines of sight through dense molecular clouds and the diffuse ISM. ABE is a cryogenically-cooled 60 cm diameter space telescope equipped with 3 cross-dispersed R-2000 spectrometers that share a single common slit. Each spectrometer measures one spectral octave and together cover the entire 2.5-20 micron region simultaneously. The spectrometers use state-of-the-art InSb and Si:As 1024x1024 pixel detectors. ABE would operate in a heliocentric, Earth drift-away orbit and have a core science mission lasting approximately 1.5 years. ABE is currently under study at NASA's Ames Research Center in collaboration with Ball Aerospace and Technologies Corp.

Teachers' and students' perceptions of seventh- and eighth-grade science education in a selected Seventh-day Adventist Union Conference  

NASA Astrophysics Data System (ADS)

Problem. Science education has long been a great concern in the United States, where less than one-third of the students perform at or above the proficient level. The purpose of this study was to investigate the status of the science program in a selected Union Conference of the Seventh-day Adventist school system. Specifically, this study investigated the perceptions of teachers and students regarding the extent to which the science program meets the criteria of the National Commission on Mathematics and Science Teaching for the 21st century and to what extent these criteria are related to academic performance as indicated by Iowa Test of Basic Skills (ITBS) science scores. Method. Two questionnaires designed by the researcher were used to get responses from 424 students in seventh and eighth grades and 68 teachers to see how this school system compares to the criteria of National Commission on Mathematics and Science Teaching for the 21 st century. Three classroom configurations were investigated in this study, namely: (a) multigrade, (b) two-grade, and (c) single-grade. Crosstabulation, one-way analysis of variance, Kruskal-Wallis test, and linear regression were used to analyze the four research questions of this study. Results. The single-grade classroom configuration received a better rating for the science criteria (p < 0.01), and students from single-grade performed significantly better than two-grade/multigrade (p < 0.01) classroom configurations on their science achievement (ITBS). There were significant relationships among science achievement and the factors that measured the criteria of the National Commission for Mathematics and Science Teaching for the 21st century. Conclusions. The differences in teaching practices explained the discrepancies in the three classroom configurations. Schools can therefore develop policies and strategies to improve the practices in the teaching and learning process in science education that were identified as being deficient by the criteria of National Commission on Mathematics and Science Teaching for the 21st century.

Brazilian research on extremophiles in the context of astrobiology  

NASA Astrophysics Data System (ADS)

Extremophiles are organisms adapted to grow at extreme ranges of environmental variables, such as high or low temperatures, acid or alkaline medium, high salt concentration, high pressures and so forth. Most extremophiles are micro-organisms that belong to the Archaea and Bacteria domains, and are widely spread across the world, which include the polar regions, volcanoes, deserts, deep oceanic sediments, hydrothermal vents, hypersaline lakes, acid and alkaline water bodies, and other extreme environments considered hostile to human life. Despite the tropical climate, Brazil has a wide range of ecosystems which include some permanent or seasonally extreme environments. For example, the Cerrado is a biome with very low soil pH with high Al+3 concentration, the mangroves in the Brazilian coast are anaerobic and saline, Pantanal has thousands of alkaline-saline lakes, the Caatinga arid and hot soils and the deep sea sediments in the Brazilian ocean shelf. These environments harbour extremophilic organisms that, coupled with the high natural biodiversity in Brazil, could be explored for different purposes. However, only a few projects in Brazil intended to study the extremophiles. In the frame of astrobiology, for example, these organisms could provide important models for defining the limits of life and hypothesize about life outside Earth. Brazilian microbiologists have, however, studied the extremophilic micro-organisms inhabiting non-Brazilian environments, such as the Antarctic continent. The experience and previous results obtained from the Brazilian Antarctic Program (PROANTAR) provide important results that are directly related to astrobiology. This article is a brief synopsis of the Brazilian experience in researching extremophiles, indicating the most important results related to astrobiology and some future perspectives in this area.

Astrobiology at Arizona State University: An Overview of Accomplishments  

NASA Technical Reports Server (NTRS)

During our five years as an NAI charter member, Arizona State University sponsored a broadly-based program of research and training in Astrobiology to address the origin, evolution and distribution of life in the Solar System. With such a large, diverse and active team, it is not possible in a reasonable space, to cover all details of progress made over the entire five years. The following paragraphs provide an overview update of the specific research areas pursued by the Arizona State University (ASU) Astrobiology team at the end of Year 5 and at the end of the 4 month and subsequent no cost month extensions. for a more detailed review, the reader is referred to the individual annual reports (and Executive Summaries) submitted to the NAI at the end of each of our five years of membership. Appended in electronic form is our complete publication record for all five years, plus a tabulation of undergraduates, graduate students and post-docs supported by our program during this time. The overarching theme of ASU s Astrobiology program was "Exploring the Living Universe: Studies of the Origin, Evolution and Distribution of Life in the Solar System". The NAi-funded research effort was organized under three basic sub- themes: 1. Origins of the Basic Building Blocks of Life. 2. Early Biosphere Evolution. and 3. Exploring for Life in the Solar System. These sub-theme areas were in turn, subdivided into Co-lead research modules. In the paragraphs that follow, accomplishments for individual research modules are briefly outlined, and the key participants presented in tabular form. As noted, publications for each module are appended in hard copy and digital formats, under the name(s) of lead co-Is.

Astrobiology: guidelines and future missions plan for the international community  

NASA Astrophysics Data System (ADS)

The search for extra-terrestrial life has been going on ever since humans realized there was more to the Universe than just the Earth. These quests have taken many forms including, but not limited to: the quest for understanding the biological origins of life on Earth; the deployment of robotic probes to other planets to look for microbial life; the analysis of meteorites for chemical and fossil remnants of extra - terrestrial life; and the search of the radio spectrum for signs of extra-solar intelligence. These searches so far have yielded hints, but no unambiguous proof of life with origins from off Earth. The emerging field of astrobiology studies the origin, distribution, and future of life in the Universe. Technical advances and new, though not conclusive, evidence of extinct microbial life on Mars have created a new enthusiasm for astrobiology in many nations. However, the next steps to take are not clear, and should a positive result be returned, the follow-on missions are yet to be defined. This paper reports on the results of an eight-week study by the students of the International Space University during the summer of 2002. The study created a source book that can be used by mission designers and policy makers to chart the next steps in astrobiology. In particular, the study addresses the following questions: What is the full set of dimensions along which we can search for extra -terrestrial life? What activities are currently underway by the international community along each of these dimensions? What are the most effective next steps that can be taken by the international space community in order to further this search (from a policy, sociological and mission point of view)? What are the proper steps for eliminating possible contamination of the Earth's biosphere? What are the issues with planetary quarantine with regards to unwanted contamination of other biospheres with terrestrial organisms? Integrating all the considerations affecting the search for the origins of the universe, this study proposes a strategy and an integrated series of missions that will advance the international astrobiology effort.

The O/OREOS mission—Astrobiology in low Earth orbit  

NASA Astrophysics Data System (ADS)

The O/OREOS (Organism/Organic Exposure to Orbital Stresses) nanosatellite is the first science demonstration spacecraft and flight mission of the NASA Astrobiology Small-Payloads Program (ASP). O/OREOS was launched successfully on November 19, 2010, to a high-inclination (72°), 650-km Earth orbit aboard a US Air Force Minotaur IV rocket from Kodiak, Alaska. O/OREOS consists of 3 conjoined cubesat (each 1000 cm3) modules: (i) a control bus; (ii) the Space Environment Survivability of Living Organisms (SESLO) experiment; and (iii) the Space Environment Viability of Organics (SEVO) experiment. Among the innovative aspects of the O/OREOS mission are a real-time analysis of the photostability of organics and biomarkers and the collection of data on the survival and metabolic activity for microorganisms at 3 times during the 6-month mission. We report on the spacecraft characteristics, payload capabilities, and present operational phase and flight data from the O/OREOS mission. The science and technology rationale of O/OREOS supports NASA's scientific exploration program by investigating the local space environment as well as space biology relevant to Moon and Mars missions. It also serves as a precursor for experiments on small satellites, the International Space Station (ISS), future free-flyers and lunar surface exposure facilities.

Finding Near-Earth Asteroid (NEA) Destinations for Human Exploration: Implications for Astrobiology  

NASA Technical Reports Server (NTRS)

The current number of known potential NEA targets for HSF is limited to those objects whose orbital characteristics are similar to that of the Earth. This is due to the projected capabilities of the exploration systems currently under consideration and development at NASA. However, NEAs with such orbital characteristics often have viewing geometries that place them at low solar elongations and thus are difficult to detect from the vicinity of Earth. While ongoing ground-based surveys and data archives maintained by the NEO Program Observation Program Office and the Minor Planet Center (MPC) have provided a solid basis upon which to build, a more complete catalog of the NEO population is required to inform a robust and sustainable HSF exploration program. Since all the present NEO observing assets are currently confined to the vicinity of the Earth, additional effort must be made to provide capabilities for detection of additional HSF targets via assets beyond Earth orbit. A space-based NEO survey telescope located beyond the vicinity of the Earth, has considerable implications for planetary science and astrobiology. Such a telescope will provide foundational knowledge of our Solar System small body population and detect targets of interest for both the HSF and scientific communities. Data from this asset will yield basic characterization data on the NEOs observed (i.e., albedo, size determination, potential for volatiles and organics, etc.) and help down select targets for future HSF missions. Ideally, the most attractive targets from both HSF and astrobiology perspectives are those NEAs that may contain organic and volatile materials, and which could be effectively sampled at a variety of locations and depths. Presented here is an overview of four space-based survey concepts; any one of which after just a few years of operation will discover many highly accessible NEO targets suitable for robotic and human exploration. Such a space-based survey mission will reveal incredible returns for several disciplines including: exploration, in situ resource utilization, planetary defense, and science. Of particular, interest to the scientific

Hexagonal Lattice PCA of the Milky Way Astrobiological Complexity  

NASA Astrophysics Data System (ADS)

We simulate the evolution of Galactic habitable zone astrobiological complexity within neocatastrophic paradigm using the probabilistic cellular automata (PCA) platform. In this short talk we compare the results of our previous square lattice 2D PCA simulations with the new results obtained from the same model on the hexagonal 2D PCA lattice. Bidimensional hexagonal lattice is more indicative of the omnidirectional real world phenomena. However, its implementation requires more computational steps at the basic level of a PCA kernel, resulting in more time-consuming computation. The resulting execution times are compared with the ones required in the rectangular lattice case. We discuss whether the hexagonal lattice can become a standard in our forthcoming code implementations.

Data management in astrobiology: challenges and opportunities for an interdisciplinary community.  

PubMed

Abstract Data management and sharing are growing concerns for scientists and funding organizations throughout the world. Funding organizations are implementing requirements for data management plans, while scientists are establishing new infrastructures for data sharing. One of the difficulties is sharing data among a diverse set of research disciplines. Astrobiology is a unique community of researchers, containing over 110 different disciplines. The current study reports the results of a survey of data management practices among scientists involved in the astrobiology community and the NASA Astrobiology Institute (NAI) in particular. The survey was administered over a 2-month period in the first half of 2013. Fifteen percent of the NAI community responded (n=114), and additional (n=80) responses were collected from members of an astrobiology Listserv. The results of the survey show that the astrobiology community shares many of the same concerns for data sharing as other groups. The benefits of data sharing are acknowledged by many respondents, but barriers to data sharing remain, including lack of acknowledgement, citation, time, and institutional rewards. Overcoming technical, institutional, and social barriers to data sharing will be a challenge into the future. Key Words: Data management-Data sharing-Data preservation. Astrobiology 14, 451-461.

Making Science Public  

NASA Astrophysics Data System (ADS)

This talk will describe a series of projects that aim to place scientific content into the public arena in free venues. Akin to public art where the works have implications of site specificity, community involvement and collaboration, these efforts have been dubbed "public science" by the authors. These initiatives attempt to reach new audiences -- particularly non-experts and casual or unintentional visitors who might not actively seek out science -- by providing events in non-traditional locations for science outreach. Might public science projects be able to play a role in enhancing and supporting society's relationship with science by embedding science content into everyday experiences? The talk will examine one project that is now largely complete ("From Earth to the Universe"), one that is ongoing ("From Earth to the Solar System"), and finally a project slated to open in 2012 ("Here, There, Everywhere"). These public science projects include content spanning cosmology, planetary science, astrobiology, Earth science, and general physics.

The AstroBiology Explorer (ABE) MIDEX Mission Concept: Using Infrared Spectroscopy to Identify Organic Molecules in Space  

NASA Technical Reports Server (NTRS)

One of the principal means by which organic compounds are detected and identified in space is by infrared spectroscopy. Past IR studies (telescopic and laboratory) have demonstrated that much of the carbon in the interstellar medium (ISM) is in complex organic species of a variety of types, but the distribution, abundance, and evolutionary relationships of these materials are not well understood. The Astrobiology Explorer (ABE) is a MIDEAST mission concept designed to conduct IR spectroscopic observations to detect and identify these materials to address outstanding important problems in astrobiology, astrochemistry, and astrophysics. Systematic studies include the observation of planetary nebulae and stellar outflows, protostellar objects, Solar System Objects, and galaxies, and multiple lines of sight through dense molecular clouds and the diffuse ISM. ABE will also search for evidence of D enrichment in complex molecules in all these environments. The mission is currently under study at NASA's Ames Research Center in collaboration with Ball Aerospace and Technologies Corp. ABE is a cryogenically-cooled 60 cm diameter space telescope equipped with 3 cryogenic cross-dispersed spectrographs that share a single common slit. The 3 spectrometers each measure single spectral octaves (2.5-5, 5-10, 10-20 microns) and together cover the entire 2.5 - 20 micron region simultaneously. The spectrometers use state-of-the-art 1024x1024 pixel detectors, with a single InSb array for the 2.5-5 micron region and two Si:As arrays for the 5-10 and 10-20 micron regions. The spectral resolution is wavelength dependent but is greater than 2000 across the entire spectral range. ABE would operate in a heliocentric, Earth drift-away orbit and is designed to take maximum advantage of this environment for cooling, thermal stability, and mission lifetime. ABE would have a core science mission lasting approximately 1.5 years.

PREFACE: International Symposium on Materials Science and Innovation for Sustainable Society - Eco-Materials and Eco-Innovation for Global Sustainability - The 21st Iketani Conference 2011  

NASA Astrophysics Data System (ADS)

Conference logo The 21st century has been called the century of environmental revolution. Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express my sincere appreciation to all the committees and secretariats, authors, participants of ECO-MATES 2011, and everybody involved in the publication of this special issue. It is a great honor for me that the special issue of Journal of Physics: Conference Series will contribute to establishing green innovations and a sustainable society.

Physics of Granular Materials: Investigations in Support of Astrobiology  

NASA Technical Reports Server (NTRS)

This publication list is submitted as a summary of the work conducted under Cooperative Agreement 1120. The goal of the 1120 research was to study granular materials within a planetary, astrophysical, and astrobiological context. This involved research on the physical, mechanical and electrostatic properties of granular systems, as well as the examination of these materials with atomic force microscopy and x-ray analysis. Instruments for analyzing said materials in planetary environments were developed, including the MECA (Mars Environment Compatibility Assessment) experiment for the MSP '01 lander, the ECHOS/MATADOR experiment for the MSP '03 lander, an ISRU experiment for the '03 lander, and MiniLEAP technology. Flight experiments for microgravity (Space Station and Shuttle) have also been developed for the study of granular materials. As expressed in the publications, work on 1120 encompassed laboratory research, theoretical modeling, field experiments, and flight experiments: a series of successful new models were developed for understanding the behavior of triboelectrostatically charged granular masses, and 4 separate instruments were selected for space flight. No inventions or patents were generated by the research under this Agreement.

A micro fluorescent activated cell sorter for astrobiology applications  

NASA Astrophysics Data System (ADS)

A micro-scale Fluorescent Activated Cell Sorter (?FACS) for astrobiology applications is under development. This device is designed to have a footprint of 7 cm x 7 cm x 4 cm and allow live-dead counts and sorting of cells that have fluorescent characteristics from staining. The ?FACS system takes advantage of microfludics to create a cell sorter that can fit in the palm of the hand. A micron-scale channel allows cells to pass by a blue diode which causes emission of marker-expressed cells which are detected by a filtered photodetector. A small microcontroller then counts cells and operates high speed valves to select which chamber the cell is collected in (a collection chamber or a waste chamber). Cells with the expressed characteristic will be collected in the collection chamber. This system has been built and is currently being tested. We are also designing a system with integrated MEMS-based pumps and valves for a small and compact unit to fly on small satellite-based biology experiments.

Life and the Universe: From Astrochemistry to Astrobiology  

NASA Technical Reports Server (NTRS)

Great strides have been made in our understanding of interstellar material thanks to advances in infrared astronomy and laboratory astrophysics. Ionized polycyclic aromatic hydrocarbons (PAHs), shockingly large molecules by earlier astrochemical standards, are widespread and very abundant throughout much of the cosmos. In cold molecular clouds, the birthplace of planets and stars, interstellar atoms and molecules freeze onto extremely cold dust and ice particles forming mixed molecular ices dominated by simple species such as water, methanol, ammonia, and carbon monoxide. Within these clouds, and especially in the vicinity of star and planet forming regions, these ices and PAHs are processed by ultraviolet light and cosmic rays forming hundreds of far more complex species, some of biogenic interest. Eventually, these are delivered to primordial planets by comets and meteorites. As these materials are the building blocks of comets and related to carbonaceous micrometeorites, they are likely to be important sources of complex organic materials delivered to habitable planets (including the primordial Earth) and their composition may be related to the origin of life. This talk will focus on the chemical evolution of these cosmic materials and their relevance to astrobiology.

Astrobiology, space and the future age of discovery.  

PubMed

Astrobiology is the study of the origins, evolution, distribution and future of life in the Universe, and specifically seeks to understand the origin of life and to test the hypothesis that life exists elsewhere than on Earth. There is a general mathematics, physics and chemistry; that is, scientific laws that obtain on Earth also do so elsewhere. Is there a general biology? Is the Universe life-rich or is Earth an isolated island of biology? Exploration in the Age of Enlightenment required the collection of data in unexplored regions and the use of induction and empiricism to derive models and natural laws. The current search for extra-terrestrial life has a similar goal, but with a much greater amount of data and with computers to help with management, correlations, pattern recognition and analysis. There are 60 active space missions, many of them aiding in the search for life. There is not a universally accepted definition of life, but there are a series of characteristics that can aid in the identification of life elsewhere. The study of locations on Earth with similarities to early Mars and other space objects could provide a model that can be used in the search for extra-terrestrial life. PMID:21220277

Widening Perspectives: The Intellectual and Social Benefits of Astrobiology (Regardless of Whether Extraterrestrial Life is Discovered or Not)  

NASA Astrophysics Data System (ADS)

Astrobiology is usually defined as the study of the origin, evolution, distribution, and future of life in the universe. As such it is inherently interdisciplinary and cannot help but engender a world view infused by a cosmic perspective. Both these attributes of the study of astrobiology are, and will increasingly prove, beneficial to society regardless of whether extraterrestrial life is actually discovered or not.

Walk Through Solar System Times: An Exhibit with an Astrobiology Emphasis  

NASA Technical Reports Server (NTRS)

In this astrobiology outreach project, we attempt to present the research of the Goddard Center for Astrobiology (GCA) in the context of the history of the Solar System. GCA research emphasizes the origin and formation of complex pre-biotic organic materials in extraterrestrial environments and explores whether the delivery of these primordial materials and water to the early Earth enabled the emergence and evolution of life. The content expounds on areas that are usually not touched upon in a timeline of the Earth's formation. The exhibit addresses the questions: How did our solar system form? How is the formation of our solar systems similar or different from others? How did the organic molecules we observe in space get to the Earth? What conditions are most suitable for life? We will address the issues and challenges of designing the exhibit and of explaining advanced astrobiology research topics to the public.

Infrared Spectroscopy of Parent Volatiles in Comets: Implications for Astrobiology  

NASA Technical Reports Server (NTRS)

Current cometary orbits provide information on their recent dynamical history. However, determining a given comet's formation region from its current dynamical state alone is complicated by radial migration in the proto-planetary disk and by dynamical interactions with the growing giant planets. Because comets reside for long periods of time in the outer Solar System, the ices contained in their nuclei (native ices) retain a relatively well-preserved footprint of when and where they formed, and this in turn can provide clues to conditions in the formation epoch. As a comet approaches the Sun, sublimation of its native ices releases parent volatiles into the coma where they can be measured spectroscopically. The past to - 15 years have seen the advent of infrared spectrometers with high sensitivity between about 2.8 and 5.0 micron, enabling a taxonomy among comets based on abundances of parent volatiles (e.g., H2O, CO, CH4, C2H6, HCN, CH30H, H2CO, NH3). Such molecules are of keen interest to Astrobiology, as they include important pre-biotic species that likely were required for the emergence of life on Earth and perhaps elsewhere. Approximately 20 comets have thus far been characterized, beginning with C/1996 82 (Hyakutake) in 1996. Molecular production rates are established through comparison of observed emission line intensities with those predicted by quantum mechanical fluorescence models. Abundances of parent volatiles (relative to H2O) vary among even the relatively small number of comets sampled, with the most volatile species (CO and CH4) displaying the largest variations. Techniques developed for measuring parent volatile abundances in comets will be discussed, as will possible implications for their formation.

Thermal Desorption/GCMS Analysis of Astrobiologically Relevant Organic Materials  

NASA Technical Reports Server (NTRS)

Several macromolecular organic materials, both biologically-derived (type II kerogen and humic acid) and abiotic in origin (Murchison insoluble organic material, cyanide polymer, and Titan tholin) were subjected to thermal desorption using a Chromatoprobe attachment on a Varian Saturn 2000 GCMS system. Each sample was heated sequentially at 100, 200, and 300 C to release volatile components. The evolved compounds were then separated on a Supelco EC-1 dimethylsilica GC column and detected by the Saturn 2000 ion trap mass spectrometer. The various types of macromolecular organic material subjected to thermal desorption produced distinctly different GCMS chromatograms at each temperature, containing fractions of both low and high chromatographic mobility. The relative amounts of detectable volatiles released at each temperature also differed, with type II kerogen and cyanide polymer containing the highest percentage of low-temperature components. In all the samples, the highest yield of released compounds occurred at 300 C. Only cyanide polymer evolved a homologous hydrocarbon series, suggesting that it is the only material among those examined that contains a truly polymeric structure. Pyrolysis/gas chromatography/mass spectrometry has been used extensively for analysis of terrestrial organic macromolecular materials, and was also part of the instrument package on the Viking landers. Thorough analysis by pyrolysis usually employs temperatures of 500 C or higher, which for in situ analyses can be problematic given spacecraft power and materials constraints. This study demonstrates that heating of organic materials of astrobiological relevance to temperatures as low as 200-300 C for short periods releases volatile components that can be analyzed by gas chromatography and mass spectrometry. Even in the absence of full pyrolysis, useful chemical information on samples can be obtained, and materials from different biological and abiological sources can be distinguished. The research described in this paper was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

Carbon molecules in space: from astrochemistry to astrobiology.  

PubMed

How complex carbonaceous molecules in space are, what their abundance is and on what timescales they form are crucial questions within cosmochemistry. Despite the large heterogeneity of galactic and interstellar regions the organic chemistry in the universe seems to follow common pathways. The largest fraction of carbon in the universe is incorporated into aromatic molecules (gaseous polycyclic aromatic hydrocarbon as well as solid macromolecular aromatic structures). Macromolecular carbon constitutes more than half of the interstellar carbon, approximately 80% of the carbon in meteorites, and is likely to be present in comets. Molecules of high astrobiological relevance such as N-heterocycles, amino acids and pre-sugars have all been identified in trace quantities (ppb) in extracts of carbonaceous meteorites. Their presence in inter- and circumstellar regions is either unknown or contentious. In any event such fragile species are easily destroyed by UV radiation, shocks and thermal processing and are unlikely to survive incorporation into Solar System material without some degradation. The more refractory material, in particular macromolecular carbon may retain an interstellar heritage more faithfully. We present laboratory measurements on the photostability of organic compounds and discuss their survival in regions with elevated UV radiation. We also show recent observations of diffuse interstellar bands indicating the presence of fullerenes. We investigate the link between the carbon chemistry in interstellar space and in the Solar System by analyzing the carbonaceous fraction of meteorites and by reviewing stable isotopic data. It also seems evident that both volatile and refractory material from carbonaceous meteoritic has been substantially altered owing to thermal and aqueous processing within the Solar System.

The SOLID (Signs Of LIfe Detector) instrument concept: an antibody microarray-based biosensor for life detection in astrobiology  

NASA Astrophysics Data System (ADS)

Immunosensors have been extensively used since many years for environmental monitoring. Different technological platforms allow new biosensor designs and implementations. We have reported (Rivas et al., 2008) a shotgun approach for antibody production for biomarker detection in astrobiology and environmental monitoring, the production of 150 new polyclonal antibodies against microbial strains and environmental extracts, and the construction and validation of an antibody microarray (LDCHIP200, for "Life Detector Chip") containing 200 different antibodies. We have successfully used the LDCHIP200 for the detection of biological polymers in extreme environments in different parts of the world (e.g., a deep South African mine, Antarctica's Dry valleys, Yellowstone, Iceland, and Rio Tinto). Clustering analysis associated similar immunopatterns to samples from apparently very different environments, indicating that they indeed share similar universal biomarkers. A redundancy in the number of antibodies against different target biomarkers apart of revealing the presence of certain biomolecules, it renders a sample-specific immuno-profile, an "immnuno-fingerprint", which may constitute by itself an indirect biosignature. We will present a case study of immunoprofiling different iron-sulfur as well as phylosilicates rich samples along the Rio Tinto river banks. Based on protein microarray technology, we designed and built the concept instrument called SOLID (for "Signs Of LIfe Detector"; Parro et al., 2005; 2008a, b; http://cab.inta.es/solid) for automatic in situ analysis of soil samples and molecular biomarkers detection. A field prototype, SOLID2, was successfully tested for the analysis of grinded core samples during the 2005 "MARTE" campaign of a Mars drilling simulation experiment by a sandwich microarray immunoassay (Parro et al., 2008b). We will show the new version of the instrument (SOLID3) which is able to perform both sandwich and competitive immunoassays. SOLID3 consists of two separate functional units: a Sample Preparation Unit (SPU), for ten different extractions by ultrasonication, and a Sample Analysis Unit (SAU), for fluorescent immunoassays. The SAU consists of ten different flow cells each of one allocate one antibody microarray (up to 2000 spots), and is equipped with an unique designed optical package for fluorescent detection. We demonstrate the performance of SOLID3 for the detection of a broad range of molecular size compounds, from the amino acid size, peptides, proteins, to whole cells and spores, with sensitivities at the ppb level.

Robotic astrobiology - the need for sub-surface penetration of Mars  

NASA Astrophysics Data System (ADS)

Recent interest in the astrobiological investigation of Mars has culminated in the only planned astrobiology-focussed robotic mission to Mars - the Beagle2 mission to be carried to Mars by the Mars Express spacecraft in 2003. Beagle2 will be primarily investigating the surface and near-surface environment of Mars. However, the results from the Viking Mars lander indicated that the Martian surface is saturated in peroxides and super-oxides which would rapidly degrade any organic material. Furthermore, recent models of gardening due to meteoritic impacts on the Martian surface suggest that the depth of this oxidising layer could extend to depths of 2-3m. Given that the discovery of organic fossilised residues will be the primary target for astrobiological investigation, this implies that future robotic astrobiology missions to Mars must penetrate to below these depths. The need to penetrate into the sub-surface of Mars has recently been given greater urgency with the discovery of extensive water ice-fields as little as 1m from the surface. We review the different technologies that make this penetration into the sub-surface a practical possibility on robotic missions. We further briefly present one such implementation of these technologies through the use of ground-penetrating moles - The Vanguard Mars mission proposal.

An ambitious programme of lunar exploration will reveal much of astrobiological interest. Examples include: (i) better characterization of the impact cratering rate in the Earth-Moon system, with implications for understanding the possible ' impact frustration ' of the origin of life; (ii) preservation of ancient meteorites blasted off Earth, Mars and Venus, which may preserve evidence of the early surface

Science Across Borders: 5th Annual Natural Health Product Research Conference--March 26-29, 2008, Toronto, Canada  

PubMed Central

Canada is experiencing a growing interest in the use of alternative therapies and products particularly natural health products (NHP). In 1997, Canadians spent around C$ 2 billion on NHP. In an attempt to catch with this popularity of NHP use, Canadian researchers and administrators from academia, industry and government jointly established the Natural Health Product Research Society of Canada (NHPRS). Since its formation, NHPRS has been organizing an annual meeting which brings together world renowned researchers and experts in the area of NHP research. For 2008, the annual NHPRS meeting took place in Toronto from the 26th to 29th of March with a focus on ‘Science Across Borders: Global Natural Health Products Research’. The scientific program was spread into three days of plenary lectures and oral presentations. The different sessions containing these talks were on: ethnobotany around the world; chemical analysis of NHP; product standards and quality control; ethnomedicine; novel analytical approaches; systemic research, nutrisciences and molecular medicine; and drug development from NHP. The meeting proved to be a great success in terms of the speakers that were invited and based on the data that was presented which highlighted recent research taking place in the field of NHP not only in Canada but from many parts of the world.
