    NSDL National Science Digital Library

    MarcoPolo: Internet Content for the Classroom is a nonprofit consortium of education organizations and the MCI Foundation "dedicated to providing the highest quality Internet content and professional development to teachers and students throughout the United States." The website began as a collection of standards-based, discipline-specific websites for K-12 teachers and now offers lesson plans, student interactive content, downloadable worksheets, links to panel-reviewed websites and additional resources. The website also provides information on the "scalable professional development program" and the "network of states partners dedicated to rolling out MarcoPolo to all teachers and aligning the content to state education standards." Visitors to the website can search the educational resources created by or reviewed by the MarcoPolo Partners, or browse the most recent and featured postings. The MarcoPolo Calendar provides information on historic events and associates them with related MarcoPolo lessons, and a monthly newsletter, MarcoGrams, highlights "common themes from space exploration to family culture" and includes "motivating warm-ups for classroom discussion" and links to other resources. Another section links to MarcoPolo websites across the nation that provide teachers with MarcoPolo content aligned to their state standards. Some resources require free registration, such as information on how to use the MarcoPolo program, free web-based training, and technology tips. The program is so comprehensive, there is even research on the impact of the MarcoPolo program so far.

His work mainly explored the development and application of Bayesian techniques to model clinical, public health, and bioinformatics questions. His contributions have led to improvements in our ability to model behavior that evolves in time, to explore systematic relationships among large sets of covariates, and to tease out the meaning of data on the role of genetic variation in the genesis of important diseases.

    It has been suggested that Western press coverage played a crucial role in the withdrawal of U.S.. support from Ferdinand Marcos and thus indirectly contributed to his subsequent fall from power in 1986. The assassination of prominent Marcos critic Benigno Aquino in August 1983 is cited as a key event in turning American support with respect to long?time ally Marcos.

    MarcoPolo-R is a sample return mission to a primitive Near-Earth Asteroid (NEA) proposed in collaboration with NASA. It will rendezvous with a primitive NEA, scientifically characterize it at multiple scales, and return a unique sample to Earth unaltered by the atmospheric entry process or terrestrial weathering. MarcoPolo-R will return bulk samples (up to 2 kg) from an organic-rich binary asteroid to Earth for laboratory analyses, allowing us to: explore the origin of planetary materials and initial stages of habitable planet formation; identify and characterize the organics and volatiles in a primitive asteroid; understand the unique geomorphology, dynamics and evolution of a binary NEA. This project is based on the previous Marco Polo mission study, which was selected for the Assessment Phase of the first round of Cosmic Vision. Its scientific rationale was highly ranked by ESA committees and it was not selected only because the estimated cost was higher than the allotted amount for an M class mission. The cost of MarcoPolo-R will be reduced to within the ESA medium mission budget by collaboration with APL (John Hopkins University) and JPL in the NASA program for coordination with ESA's Cosmic Vision Call. The baseline target is a binary asteroid (175706) 1996 FG3, which offers a very efficient operational and technical mission profile. A binary target also provides enhanced science return. The choice of this target will allow new investigations to be performed more easily than at a single object, and also enables investigations of the fascinating geology and geophysics of asteroids that are impossible at a single object. Several launch windows have been identified in the time-span 2020-2024. A number of other possible primitive single targets of high scientific interest have been identified covering a wide range of possible launch dates. The baseline mission scenario of MarcoPolo-R to 1996 FG3 is as follows: a single primary spacecraft provided by ESA, carrying the Earth Re-entry Capsule, sample acquisition and transfer system provided by NASA, will be launched by a Soyuz-Fregat rocket from Kourou into GTO and using two space segment stages. Two similar missions with two launch windows, in 2021 and 2022 and for both sample return in 2029 (with mission duration of 7 and 8 years), have been defined. Earlier or later launches, in 2020 or 2024, also offer good opportunities. All manoeuvres are carried out by a chemical propulsion system. MarcoPolo-R takes advantage of three industrial studies completed as part of the previous Marco Polo mission (see ESA/SRE (2009)3, Marco Polo Yellow Book) and of the expertise of the consortium led by Dr. A.F. Cheng (PI of the NASA NEAR Shoemaker mission) of the JHU-APL, including JPL, NASA ARC, NASA LaRC, and MIT.

    The mineralogy of the two uranium deposits (Victorino and San Marcos I) of Sierra San Marcos, located 30 km northwest of Chihuahua City, Mexico, was studied by optical microscopy, powder X-ray diffraction with Rietveld analysis, scanning electron microscopy with energy dispersive X-ray analysis, inductively coupled plasma spectrometry, and gamma spectrometry. At the San Marcos I deposit, uranophane Ca(UO2)2Si2O7·6(H2O) (the dominant mineral at both deposits) and metatyuyamunite Ca(UO2)(V2O8)·3(H2O) were observed. Uranophane, uraninite (UO2+x), masuyite Pb(UO2)3O3(OH)·3(H2O), and becquerelite Ca(UO2)6O4(OH)6 ·(8H2O) are present at the Victorino deposit. Field observations, coupled with analytical data, suggest the following sequence of mineralization: (1) deposition of uraninite, (2) alteration of uraninite to masuyite, (3) deposition of uranophane, (4) micro-fracturing, (5) calcite deposition in the micro-fractures, and (6) formation of becquerelite. The investigated deposits were formed by high-to low-temperature hydrothermal activity during post-orogenic evolution of Sierra San Marcos. The secondary mineralization occurred through a combination of hydrothermal and supergene alteration events. Becquerelite was formed in situ by reaction of uraninite with geothermal carbonated solutions, which led to almost complete dissolution of the precursor uraninite. The Victorino deposit represents the second known occurrence of becquerelite in Mexico, the other being the uranium deposits at Peña Blanca in Chihuahua State.

    MARCO POLO is a joint European-Japanese sample return mission to a Near-Earth Object (NEO), selected by ESA in the framework of COSMIC VISION 2015-2025 for an assessment study scheduled to last until October 2009. This Euro-Asian mission will go to a primitive Near-Earth Object (NEO), such as C or D-type, scientifically characterize it at multiple scales, and bring samples back to Earth for detailed scientific investigation. NEOs are part of the small body population in the Solar System, which are leftover building blocks of the Solar System formation process. They offer important clues to the chemical mixture from which planets formed about 4.6 billion years ago. The scientific objectives of Marco Polo will therefore contribute to a better understanding of the origin and evolution of the Solar System, the Earth, and the potential contribution of primitive material to the formation of Life. Marco Polo is based on a launch with a Soyuz Fregat and consists of a Mother Spacecraft (MSC), possibly carrying a lander. The MSC would approach the target asteroid and spend a few months for global characterization of the target to select a sampling site. Then, the MSC would then descend to retrieve several samples which will be transferred to a Sample Return Capsule (SRC). The MSC would return to Earth and release the SRC into the atmosphere for ground recovery. The sample of the NEO will then be available for detailed investigation in ground-based laboratories. In parallel to JAXA considering how to perform the mission, ESA has performed a Marco Polo study in their Concurrent Design Facility (CDF). Two parallel industrial studies will start in September 2008 to be conducted in Europe for one year. The scientific objectives addressed by the mission and the current status of the mission study (ESA-JAXA) will be presented and discussed.

    Patients with altered skin immunity, such as individuals with atopic dermatitis (AD), can have a life-threatening disruption of the epidermis known as eczema vaccinatum (EV) after vaccinia virus (VV) infection of the skin. Here, we sought to better understand the mechanism(s) by which VV associates with keratinocytes. The class A scavenger receptor known as MARCO (macrophage receptor with collagenous structure) is expressed on human and mouse keratinocytes and found to be abundantly expressed in the skin of patients with AD. VV bound directly to MARCO, and overexpression of MARCO increased susceptibility to VV infection. Furthermore, ligands with affinity for MARCO, or excess soluble MARCO, competitively inhibited VV infection. These findings indicate that MARCO promotes VV infection and highlights potential new therapeutic strategies for prevention of VV infection in the skin. PMID:25089661

    The principal scientific objective of the Marco Polo mission is to return unaltered NEO materials. Marco Polo will allow us to analyze the samples in terrestrial laboratories, thereby obtaining measurements that cannot yet beperformed from a robotic spacecraft. The selection of the target asteroids for the mission has important consequences in terms of mission design, constraints, and operational requirements. A list of asteroids as possible targets for the Marco Polo mission has been drawn, taken into account both dynamical and physical constraints. The key parameters of this list were the accessibility of the object (the delta-V amount for the encounter with the target) and the desirable, primitive composition requirements of the target deduced from the groundbased data (mainly from colors and spectroscopy). While the accessibility is dealing with space technological achievements, the primitive composition of the target is oriented toward the research on asteroids belonging to D-, T-, or C-type classes. For some of the possible targets, the physical data are sparse and reveals only partial knowledge of these objects while for some of them no spectroscopic investigations are yet available in the IR spectral region. To improve the situation, observations of asteroids 1917, 8567, 16960, 156452, 163000, 164400, and 2001 SG286 were obtained using SpeX/IRTF in the 0.8-2.5µm spectral region. The analysis of their NIR spectra reveals that many of these objects belong to the S-type complex (DeMeo, Icarus 202, 2009). The exception is the asteroid 2001 SG286, for which the spectrum is flat, similar to C-complex. The analysis of slopes, band strengths, and the most probable mineralogical and meteorite analog models will be presented.

    MARCO POLO is a joint European-Japanese sample return mission to a Near-Earth Object. This Euro-Asian mission will go to a primitive Near-Earth Object (NEO), which we anticipate will contain primitive materials without any known meteorite analogue, scientifically characterize it at multiple scales, and bring samples back to Earth for detailed scientific investigation. Small bodies, as primitive leftover building blocks of the Solar System formation process, offer important clues to the chemical mixture from which the planets formed some 4.6 billion years ago. Current exobiological scenarios for the origin of Life invoke an exogenous delivery of organic matter to the early Earth: it has been proposed that primitive bodies could have brought these complex organic molecules capable of triggering the pre-biotic synthesis of biochemical compounds. Moreover, collisions of NEOs with the Earth pose a finite hazard to life. For all these reasons, the exploration of such objects is particularly interesting and urgent. The scientific objectives of MARCO POLO will therefore contribute to a better understanding of the origin and evolution of the Solar System, the Earth, and possibly Life itself. Moreover, MARCO POLO provides important information on the volatile-rich (e.g. water) nature of primitive NEOs, which may be particularly important for future space resource utilization as well as providing critical information for the security of Earth. MARCO POLO is a proposal offering several options, leading to great flexibility in the actual implementation. The baseline mission scenario is based on a launch with a Soyuz-type launcher and consists of a Mother Spacecraft (MSC) carrying a possible Lander named SIFNOS, small hoppers, sampling devices, a re-entry capsule and scientific payloads. The MSC leaves Earth orbit, cruises toward the target with ion engines, rendezvous with the target, conducts a global characterization of the target to select a sampling site, and delivers small hoppers (MINERVA type, JAXA) and SIFNOS. The latter, if added, will perform a soft landing, anchor to the target surface, and make various in situ measurements of surface/subsurface materials near the sampling site. Two surface samples will be collected by the MSC using “touch and go” manoeuvres. Two complementary sample collection devices will be used in this phase: one developed by ESA and another provided by JAXA, mounted on a retractable extension arm. After the completion of the sampling and ascent of the MSC, the arm will be retracted to transfer the sample containers into the MSC. The MSC will then make its journey back to Earth and release the re-entry capsule into the Earth’s atmosphere.

    The Marco Polo NEO sample return M-class mission has been selected for assessment study within the ESA Cosmic Vision 2015-2025 program. The Marco Polo mission proposes to do a sample return mission to Near Earth Asteroid. With this mission we have the opportunity to return for study in Earth-based laboratories a direct sample of the earliest record of how our solar system formed. The landing site and sample selection will be the most important scientific decision to make during the course of the entire mission. The imaging spectrometer is a key instrument being capable to characterize the mineralogical composition of the entire asteroid and to analyze the of the landing site and the returned sample in its own native environment. SETA is a Hyperspectral Imaging Spectrometer able to perform imaging spectroscopy in the spectral range 400-3300 nm for a complete mapping of the target in order to characterize the mineral properties of the surface. The spectral sampling is of at least 20 nm and the spatial resolution of the order of meter. SETA shall be able to return a detailed determination of the mineralogical composition for the different geologic units as well as the overall surface mineralogy with a spatial resolution of the order of few meters. These compositional characterizations involve the analysis of spectral parameters that are diagnostic of the presence and composition of various mineral species and materials that may be present on the target body. Most of the interesting minerals have electronic and vibrational absorption features in their VIS-NIR reflectance spectra. The SETA design is based on a pushbroom imaging spectrometer operating in the 400-3300 nm range, using a 2D array HgCdTe detector. This kind of instrument allows a simultaneous measurement of a full spectrum taken across the field of view defined by the slit's axis (samples). The second direction (lines) of the hyperspectral image shall be obtained by using the relative motion of the orbiter with respect to the target or by using a scan mirror. The SETA optical concept is mostly inherited from the SIMBIO-SYS/VIHI (Visible Infrared Hyperspectral Imager) imaging spectrometer aboard Bepi Colombo mission but also from other space flying imaging spectrometers, such as VIRTIS (on Rosetta and Venus Express, VIR on DAWN).

    The first astronaut of the European Astronaut Corps of Italian nationality, Roberto Vittori, will fly on a Soyuz capsule at the end of April 2002, opening a new era of space flight. The mission, sponsored by the Italian Space Agency, has been developed in the framework of an ESA- ROSAVIAKOSMOS agreement, reached in order to give European astronauts additional possibilities to fly. It's the first mission of this kind. In addition to that, this is the real first time in which a Soyuz mission is in the hands of two cosmonauts, and one of them is non Russian. On the same flight, in fact, Mark Shuttleworth, the second tourist in the history of space activities, is going to fly, performing also a set of scientific experiments. Marco Polo is also the first mission in which the two Agencies, ASI and ESA, are developing a joint commercialisation program, devoted to attire sponsors for improving research and development activities in the Human Spaceflight area. This will allow the two agencies to improve also the quality of life on Earth. A comprehensive scientific program is also foreseen accompanying Vittori on board, mainly in the field of life science. Experiments devoted to neurophysiology, arms rehabilitation, test of new materials for dressing in space, evaluation of the behaviour of the Nobel Prize Montalcini discovery named NGF (Nerve Growth Factor) will be performed on board. A R&D payload for Blood Pressure Measurements could have in the future commercial spin-off. In addition, a possible institutional sponsorship of the World Health Organization is under discussion. It will be the real first time in which a space mission gets this kind of sponsorship, and this strictly related to the World Health Day this year, devoted in promoting health throughout movement, i.e. "Move for Health". The Italian Space Agency proposed a joint combination of the two slogans, coupling the "Move for Health" message with the Italian "Space for Health" one. This is because of the Marco Polo scientific program, and because of an advanced training and rehabilitation protocol we have studied, to be applied to old population in order to improve their quality of life, through the parallelism between astronauts (in microgravity conditions) and aging population. The mission, at the time of the World Space Congress, will be already performed and the results can be presented.

    A major goal for NASA's human spaceflight program is to send astronauts to near-Earth asteroids (NEAs) in the coming decades. Missions to NEAs would undoubtedly provide a great deal of technical and engineering data on spacecraft operations for future human space exploration while conducting in-depth scientific examinations of these primitive objects. However, prior to sending human explorers to NEAs, robotic investigations of these bodies would be required in order to maximize operational efficiency and reduce mission risk. These precursor missions to NEAs would fill crucial strategic knowledge gaps concerning their physical characteristics that are relevant for human exploration of these relatively unknown destinations. Therefore robotic investigations of NEAs, such as ESA's Marco Polo-R sample return mission to 2008 EV5, would allow NASA and its international partners to gain critical operational experience in performing complex tasks (e.g., close proximity operations, surface sample collection, etc.) under microgravity conditions at or near the surface of a potential human destination. This would provide an important synergy between the worldwide Science and Exploration communities, which will be crucial for development of future international deep space exploration architectures and has potential benefits for future exploration of other destinations beyond low-Earth orbit.

    We reported that murine tumor lysate-pulsed dendritic cells (TP-DC) could elicit tumor-specific CD4(+) and CD8(+) T cells in vitro and in vivo. In some limited cases, TP-DC treatments in vivo could also result in regression of established subcutaneous tumors and lung metastases. By gene array analysis, we reported a high level of expression of a novel member of the cell surface class A scavenger receptor family, MARCO, by murine TP-DC compared to unpulsed DC. MARCO is thought to play an important role in the immune response by mediating binding and phagocytosis, but also in the formation of lamellipodia-like structures and dendritic processes. We have now examined the biologic and therapeutic implications of MARCO expressed by TP-DC. In vitro exposure of TP-DC to a monoclonal anti-MARCO antibody resulted in a morphologic change of rounding with disappearance of dendritic-like processes. TP-DC remained viable after anti-MARCO antibody treatment; had little, if any, change in production of IL-10, IL-12p70 and TNF-alpha; but demonstrated enhanced migratory capacity in a microchemotaxis assay. The use of a selective inhibitor showed MARCO expression to be linked to the p38 mitogen-activated protein kinase (MAPK) pathway. In vivo, anti-MARCO antibody treated TP-DC showed better trafficking from the skin injection site to lymph node, enhanced generation of tumor-reactive IFN-gamma producing T cells, and improved therapeutic efficacy against B16 melanoma. These results, coupled with our finding that human monocyte-derived DC also express MARCO, could have important implications to human clinical DC vaccine trials. PMID:20054688

    Alveolar macrophages (AMs) avidly bind and ingest inhaled environmental particles and bacteria. To identify the particle binding receptor(s) on human AMs, we used functional screening of anti-human AM hybridomas and isolated a mAb, PLK-1, which inhibits AM binding of unopsonized particles (e.g., TiO2, latex beads; 63 +/- 5 and 67 +/- 4% inhibition, respectively, measured by flow cytometry; n = 11) and unopsonized bacteria ( approximately 84 and 41% inhibition of Escherichia coli and Staphylococcus aureus binding by mAb PLK-1, respectively). The PLK-1 Ag was identified as the human class A scavenger receptor (SR) MARCO (macrophage receptor with collagenous structure) by observing specific immunolabeling of COS cells transfected with human MARCO (but not SR-AI/II) cDNA and by immunoprecipitation by PLK-1 of a protein of appropriate molecular mass (approximately 70 kDa) from both normal human bronchoalveolar lavage cells (>90% AMs) and human MARCO-transfected COS cells. PLK-1 also specifically inhibited particle binding by COS cells, only after transfection with human MARCO cDNA. Immunostaining showed specific labeling of AMs within human lung tissue, bronchoalveolar lavage samples, as well as macrophages in other sites (e.g., lymph node and liver). Using COS transfectants with different truncated forms of MARCO, allowed epitope mapping for the PLK-1 Ab to MARCO domain V between amino acid residues 420 and 431. A panel of Abs to various SRs identified expression on AMs, but failed to inhibit TiO2 or S. aureus binding. The data support a dominant role for MARCO in the human AM defense against inhaled particles and pathogens. PMID:16237101

  9. Marco Polo: Hunting and Capture of Material from a Primitive Asteroid

    Licandro, Javier

    A description of the Spanish contribution to the Marco Polo mission and of the mission itself is presented. Marco Polo is a joint European-Japanese mission of sample return from a Near Earth Object (NEO). Submitted to ESA on July 2007 in the framework of the Cosmic Vision 2015-2025, Marco Polo passed the first evaluation process on October 2007. Seventeen Spanish researchers belonging to six Spanish institutes signed the proposal. The mission is planned to visit a primitive NEO, belonging to a class that cannot be related to known meteorite types, to characterize it at multiple scales, and to bring samples back to Earth. Marco Polo will give us the first opportunity for detailed laboratory study of the most primitive materials that formed the planets. This will allow us to improve our knowledge on the processes which governed the origin and early evolution of the Solar System, and possibly of the life on Earth. Three Spanish institutes are involved in the feasibility studies of two instruments: the THERmal MAPper (THERMAP) and the Marco Polo Camera System (MPCS).

    The scavenger receptors expressed by macrophages are thought to play an important role in the immune response against bacteria by mediating binding and phagocytosis. A novel member of the class A scavenger receptor family, macrophage receptor with collagenous structure (MARCO), has recently been identified. In this study we have generated a panel of mAbs with specificities for different domains of this receptor. Two of those reacting with the C-terminal cysteine-rich domain block ligand binding of MARCO. The in vivo expression of this murine receptor is normally restricted to distinct populations of macrophages in the spleen and lymph nodes. During bacillus Calmette-Guérin (BCG) infection, during bacterial sepsis, or after the injection of purified LPS, however, the expression of MARCO is rapidly induced on macrophages in other tissues, including Kupffer cells in the liver. Using the mouse macrophage cell line J774.2, it was shown that LPS stimulation up-regulates surface expression of MARCO in a dose- and time-dependent fashion. The proinflammatory cytokines IL-1, IL-6, TNF-alpha, and IFN-gamma had little or no effect. Using inhibitory mAbs, the relevance of MARCO for the clearance of circulating bacteria in vivo was determined. Although the overall elimination of live Escherichia coli and Staphylococcus aureus from the blood did not appear to be affected by treatment with these Abs, the capturing of heat-killed bacteria by macrophages in the marginal zone areas of the spleen was clearly inhibited. This study suggests a role for MARCO in the host antibacterial defense. PMID:9916718

    The internal structure of NEAs remains largely unknown. It is a key point for the understanding of asteroid accretion and dynamical evolution. From a science point of view, the internal structure is also a key point for the understanding of asteroid accretion and dynamical evolution. For risk management and mitigation, it is required to characterize whether a small asteroid will survive the transit through the atmosphere and also to define a deflection policy. There are some indirect evidences that a rubble pile structure is really common at least for objects larger than a few hundreds of meters in diameter. But a more precise characterisation of the internal structure is required, such as the size and the structure of the main blobs and their distribution within the NEAs main body as well as a statistical characterisation of the surface regolith in term of density and size distribution. Radar tomography is the only way to image the internal structure from decimetric to global scale in order to better understand the nature of the primary object and its posterior alterations. It is also a way to estimate the ratio between micro- and macro-porosity. Bistatic radar tomography is an original technique, developed with the CONSERT Experiment (Rosetta / ESA) to image ant characterize the internal structures of 67P/Churyumov-Gerasimeko with a signal transmitted from the Orbiter to the Lander. By regards to a more classical monostatic radar like Marsis (MarsExpress/ESA), this bistatic configuration requires limited resources (mass, power and dataflow) and increases the capacity of deep sounding. So ASSERT (ASteroid Sounding Experiment by Radiowave Transmission) is proposed to instrument a MASCOT-type lander e.g. as payload of the ESA Marco Polo R mission (ESA). The first addressed question is a rubble pile or a monolithic body: For a rubble pile, the tomography will allow to estimate the size distribution of the boulders by direct imaging or statistical analysis of the scattered signal. The estimation of the mean permittivity of the blobs is a way to estimate the macro- versus micro-porosity. Its spatial variations highlight the heterogeneity of the parent bodies and segregation mechanism during reaccretion. - And for a monolithic object, we can expect only micro-porosity. Then images of the body interior and spatial distributions of the permittivity give the heterogeneity. In a further analysis, the characterization of the heterogeneity by statistical or imagery approach is a key point to understand asteroid accretion and evolution: - is this body accreted or re-accreted from the same material or not, from similar parent bodies or not? - is there some evidence of collisional metamorphism with change in the porosity and or mineralogy? - is there some evidence of metamorphism per hydration? This advanced interpretation will be based on the sample return analysis and constitutes a complete recontextualization of the analyzed samples at the global body scale

    Alveolar macrophages (AMs) express the class A scavenger receptors (SRAs) macrophage receptor with collagenous structure (MARCO) and scavenger receptor AI/II (SRA-I/II), which recognize oxidized lipids and provide innate defense against inhaled pathogens and particles. Increased MARCO expression in lungs of ozone-resistant mice suggested an additional role protecting against inhaled oxidants. After ozone exposure, MARCO–/– mice showed greater lung injury than did MARCO+/+ mice. Ozone is known to generate oxidized, proinflammatory lipids in lung lining fluid, such as 5?,6?-epoxycholesterol (?-epoxide) and 1-palmitoyl-2-(9?-oxo-nonanoyl)-glycerophosphocholine (PON-GPC). Intratracheal instillation of either lipid caused substantial neutrophil influx in MARCO–/– mice, but had no effect in MARCO+/+ mice. Normal AMs showed greater uptake in vitro of ?-epoxide compared with MARCO–/– AMs, consistent with SRA function in binding oxidized lipids. SR-AI/II–/– mice showed similar enhanced acute lung inflammation after ?-epoxide or another inhaled oxidant (aerosolized leachate of residual oil fly ash). In contrast, subacute ozone exposure did not enhance inflammation in SR-AI/II–/– versus SR-AI/II+/+ mice, reflecting increased AM expression of MARCO. These data identify what we believe to be a novel function for AM SRAs in decreasing pulmonary inflammation after oxidant inhalation by scavenging proinflammatory oxidized lipids from lung lining fluids.

    MarcoPolo-R is a sample return mission to a primitive Near-Earth Asteroid (NEA) selected in February 2011 for the Assessment Study Phase in the framework of ESA's Cosmic Vision 2 program. MarcoPolo-R is a European-led mission with a proposed NASA contribution. MarcoPolo-R takes advantage of three industrial studies completed as part of the previous Marco Polo mission (see ESA/SRE (2009)3). The aim of the new Assessment Study is to reduce the cost of the mission while maintaining its high science level, on the basis of advanced studies and technologies, optimization of the mission, and consolidation of the collaboration with other partners (NASA, AEB…). The main goal of the MarcoPolo-R mission is to return unaltered NEA material for detailed analysis in ground-based laboratories. The limited sampling provided by meteorites does not offer the most primitive material available in near-Earth space. More primitive material, having experienced less alteration on the asteroid, will be more friable and would not survive atmospheric entry in any discernible amount. Only in Earth laboratories can instruments measure the individual components of the complex mixture of materials that forms an asteroid regolith with the necessary precision and sensitivity to determine their precise chemical and isotopic composition. Such measurements are vital for revealing the evidence of stellar, interstellar medium, pre-solar nebula and parent body processes that are retained in primitive asteroidal material, unaltered by atmospheric entry or terrestrial contamination. It is no surprise therefore that sample return missions are considered a priority by a number of the leading space agencies. MarcoPolo-R will rendezvous with a unique kind of target, a primitive binary NEA, scientifically characterize it at multiple scales, and return a unique pristine sample to Earth unaltered by the atmospheric entry process or terrestrial weathering. The baseline target of MarcoPolo-R is the primitive binary NEA (175706) 1996 FG3, which offers a very efficient operational and technical mission profile. A binary target also provides enhanced science return: the choice of this target will allow new investigations to be performed including those of the fascinating geology and geophysics of asteroids that are impossible to obtain from a single object. Precise measurements of the mutual orbit and rotation state of both components can be used to probe higher-level harmonics of the gravitational potential, and therefore the internal structure. A unique opportunity is offered to study the dynamical evolution driven by the YORP/ Yarkovsky thermal effects. Possible migration of regolith on the primary from poles to equator allows the increasing maturity of asteroidal regolith with time to be expressed as a latitude-dependent trend, with the most-weathered material at the equator matching what is seen in the secondary. MarcoPolo-R will allow us to study the most primitive materials available to investigate early solar system formation processes. Moreover, MarcoPolo-R will provide a sample from a known target with known geological context. Direct investigation of both the regolith and fresh interior fragments is also impossible by any means other than sample return.

    An interview with Vincent DeMarco, President of the Maryland Citizen's Health Initiative, reviews the history and strategies used to win victories for public health on gun policy and tobacco taxes and to seek passage of higher alcohol taxes in the state of Maryland. DeMarco emphasizes the need to build broad coalitions, to engage policy makers at election time and not just or primarily during legislative sessions, and to take advantage of the power of the news media as a microphone for reaching millions of possible supporters. The interview concludes with recommendations for public health training and practitioners in order to become successful policy advocates in a rapidly changing media and political landscape.

    MARCO POLO is a joint European-Japanese sample return mission to a Near-Earth Object (NEO), selected by ESA in the framework of COSMIC VISION for an assessment study. This Euro-Asian mission will go to a primitive NEO, such as C or D type, scientifically characterize it at multiple scales, and bring samples back to Earth for detailed scientific investigation. NEOs are part of the small body population in the solar system, which are leftover building blocks of the solar system formation process. They offer important clues to the chemical mixture from which planets formed about 4.6 billion years ago. The scientific objectives of Marco Polo will therefore contribute to a better understanding of the origin and evolution of the Solar System, the Earth, and possibly Life itself. Marco Polo is based on a launch with a Soyuz Fregat and consists of a Mother Spacecraft (MSC), possibly carrying a lander. The MSC would approach the target asteroid and spend a few months for global characterization of the target to select a sampling site. Then, the MSC would then descend to retrieve, using a "touch and go" manoeuvre, several samples which will be transferred to a Sample Return Capsule (SRC). The MSC would return to Earth and release the SRC into the atmosphere for ground recovery. The sample of the NEO will then be available for detailed investigation in ground-based laboratories. The scientific objectives addressed by the mission and the current status of the mission study (ESA-JAXA) will be presented and discussed.

    Spatial and temporal distribution of the radioisotopes concentrations were determined in sediments near the surface and core samples extracted from two reservoirs located in an arid region close to Chihuahua City, Mexico. At San Marcos reservoir one core was studied, while from Luis L. Leon reservoir one core from the entrance and another one close to the wall were investigated. 232Th-series, 238U-series, 40K and 137Cs activity concentrations (AC, Bq kg-1) were determined by gamma spectrometry with a high purity Ge detector. 238U and 234U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to 210Pb activities. Results were verified by 137Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High 238U-series AC values were found in sediments from San Marcos reservoir, because this site is located close to the Victorino uranium deposit. Low AC values found in Luis L. Leon reservoir suggest that the uranium present in the source of the Sacramento - Chuviscar Rivers is not transported up to the Conchos River. Activity ratios (AR) 234U/overflow="scroll">238U and 238U/overflow="scroll">226Ra in sediments have values between 0.9-1.2, showing a behavior close to radioactive equilibrium in the entire basin. 232Th/overflow="scroll">238U, 228Ra/overflow="scroll">226Ra ARs are witnesses of the different geological origin of sediments from San Marcos and Luis L. Leon reservoirs.

  5. Evaluation of Acoustic Doppler Velocity Meters to Quantify Flow From Comal Springs and San Marcos Springs, Texas

    2008-01-01

    Comal Springs and San Marcos Springs are the two largest springs in Texas, are major discharge points for the San Antonio segment of the Edwards aquifer, and provide habitat for several Federally listed endangered species that depend on adequate springflows for survival. It is therefore imperative that the Edwards Aquifer Authority have accurate and timely springflow data to guide resource management. Discharge points for Comal Springs and San Marcos Springs are submerged in Landa Lake and in Spring Lake, respectively. Flows from the springs currently (2008) are estimated by the U.S Geological Survey in real time as surface-water discharge from conventional stage-discharge ratings at sites downstream from each spring. Recent technological advances and availability of acoustic Doppler velocity meters (ADVMs) now provide tools to collect data (stream velocity) related to springflow that could increase accuracy of real-time estimates of the springflows. The U.S. Geological Survey, in cooperation with the Edwards Aquifer Authority, did a study during May 2006 through September 2007 to evaluate ADVMs to quantify flow from Comal and San Marcos Springs. The evaluation was based on two monitoring approaches: (1) placement of ADVMs in important spring orifices - spring run 3 and spring 7 at Comal Springs, and diversion spring at San Marcos Springs; and (2) placement of ADVMs at the nearest flowing streams - Comal River new and old channels for Comal Springs, Spring Lake west and east outflow channels and current (2008) San Marcos River streamflow-gaging site for San Marcos Springs. For Comal Springs, ADVM application at spring run 3 and spring 7 was intended to indicate whether the flows of spring run 3 and spring 7 can be related to total springflow. The findings indicate that velocity data from both discharge features, while reflecting changes in flow, do not reliably show a direct relation to measured streamflow and thus to total Comal Springs flow. ADVMs at the Comal River new channel and old channel sites provide data that potentially could yield more accurate real-time estimates of total Comal Springs flow than streamflow measured at the downstream Comal River site. For San Marcos Springs, the findings indicate shortcomings with ADVM installations at diversion spring and in the west and east outflow channels. However, the accuracy of streamflow measured at the San Marcos River gage as an estimate of real-time San Marcos Springs flow could potentially be increased through use of ADVM data from that site.

    The implementation of the telescience concept and its test in precursor missions is mandatory for experiment operations in the Columbus era with respect to enhancements in science quality and quantity. During the German D2 Spacelab mission, scheduled for spring 1993, a fluid physics experiment (MARCO, MARangoni COnvection in an open boat) will be performed in the telescience mode, using the HOLOP-D2 (HOLographic OPtics laboratory) experiment facility. MARCO will be remotely operated by the experimenter from a USOC (User Support and Operations Center). DLR/MUSC (Microgravity User Support Center, located at Cologne, Germany) will play the role of this USOC, being connected to DLR/GSOC (German Space Operations Center, located in Oberpfaffenhofen, Germany) via remote data, voice and video lines. Telescience with MARCO/HOLOP is a joint effort between DARA GmbH (Deutsche Agentur für Raumfahrt-Angelegenheiten), DLR (Deutsche Forschungsanstalt für Luft- und Raumfahrt e.V.) and ESA (European Space Agency).

    Marco Polo is a sample return mission to a Near-Earth Object (NEO). It is proposed to be performed in collaboration between the European Space Agency (ESA) and the Japanese Space Agency (JAXA). Both JAXA and ESA are currently performing Phase-A studies for this mission; within ESA, the mission is studied as part of the Cosmic Vision 2015-2025 Programme. The main objective of the mission is to return unmodified material from a primitive NEO to the Earth to allow its accurate analysis in ground-based laboratories. These primitive NEOs are part of the small body population that represents the leftover building blocks of the Solar System formation process. They offer important clues to the chemical mixture from which the planets formed about 4.6 billion years ago and carry records both of the Solar System's birth and early phases. In addition, the mission will allow studying the geological evolution and physical properties of small bodies. Marco Polo will provide the first opportunity for detailed laboratory study of the most primitive materials that formed the terrestrial planets and advance our understanding of some of the fundamental issues in the origin and early evolution of the Solar System, the Earth and possibly life itself. Determining the physical properties of a NEO will also help assessing mitigation strategies for the impact risk of such an object on the Earth. This presentation will focus on the ESA side of the assessment study. The technical development status in Europe will be presented.

    We are entering in a new era of space exploration defined by sample return missions. The study of extraterrestrial samples in the laboratory has given us many insights to Solar System formation and evolution, but is hampered by having to rely on the arrival of meteorites -fairly random samples from asteroids, the Moon and Mars. There is now increased interest from the scientific community in the acquisition of samples from specific parent-bodies; this is reflected by proposals for an increasing number of sample return missions within international programs of Solar System exploration. The study of extraterrestrial samples in laboratory provides new opportunities to advance fun-damental issues on the origin and evolution of the Solar System, on primordial cosmochemistry and on nature of the building blocks of terrestrial planets. Samples returned from primitive carbonaceous small bodies could help us in deciphering relevant clues on the origin and early evolution of life on Earth. Once returned on Earth, samples will undergo preliminary charac-terization and classification within dedicated sample curation facilities before being delivered to worldwide laboratories for detailed investigation of the elemental and isotopic compositions, mineralogy, petrology, organic and interstellar grain inventories, etc. The samples returned from the surface of a primitive NEO will contain material more primitive than currently avail-able from meteorites as this is generally lost during atmospheric entry, with only more coherent meteorites, the product of asteroidal modification, surviving to be collected on the surface of the Earth. Marco Polo was shortlisted for the assessment phase of ESA's Cosmic Vision program to perform a sample return from a primitive Near-Earth Object (NEO), such as a C-or D-type asteroid or extinct comet. Although the scientific objectives were very highly rated it was not selected for mission development as an ESA-only Medium Mission because it exceeded cost envelope. However, in view of the evolving international context, Marco Polo has gathered the interest of a huge scientific community and it is now proposed as a potential participation in missions currently under discussion within other agencies. In this talk Marco Polo's scientific case and future perspectives will be presented.

    Fournier, R.O.; Hanshaw, B.B.

    1986-01-01

    The chemical and isotopic compositions of hot springs in the San Marcos region of Guatemala are internally consistent with a hydrologic model in which a deep 240??C reservoir and one or more shallow 195-200??C reservoirs are present. Variations in hot-spring water compositions results from a combination of boiling, mixing with cold, dilute water, and chemical re-equilibration with decreasing temperature. The recharge water for the deep 240??C reservoir is isotopically heavier than the local meteoric water and probably comes from many kilometers to the west or southwest. The water in the shallow reservoir is a mixture of the 240??C water with about 20 ?? 5% of cold, locally derived meteoric water. After mixing, the water in the shallow reservoir re-equilibrates with reservoir rock at 195-200??C. In some places additional mixing with cold water occurs after water leaves the shallow reservoir. ?? 1986.

    We present THERMAP, a mid-infrared (8-16 ?m) spectro-imager based on uncooled micro-bolometer detector arrays. Due to the recent technological development of these detectors, which have undergone significant improvements in the last decade, we wanted to test their performances for a space mission to small bodies in the inner Solar System. THERMAP was selected by ESA in January 2012 for a one year assessment study, in the framework of a call for declaration of interest in science instrumentation for the Marco Polo R Cosmic Vision mission. In this paper, we present some results of this study and in particular demonstrate that the new generation of uncooled micro-bolometer detectors has all the imaging and spectroscopic capabilities to fulfill the scientific objectives of the Marco Polo R mission. THERMAP scientific objectives - The midinfrared instrument of the Marco Polo R mission must be able i) to determine the surface temperature by mapping the entire surface with an absolute accuracy of at least 5 K (goal 1 K) above 200 K, ii) to determine the thermal inertia with an accuracy of 10% and iii) to determine the surface composition by mapping the entire surface with a spectral resolution of 70 between 8 and 16 ?m. The above mappings should be performed with a spatial resolution of 10 m for the entire surface (global characterization) and 10 cm for the sampling sites (local characterization). THERMAP imaging capabilities - In order to test the imaging capabilities of the THERMAP uncooled microbolometer detector, we set up an experiment based on a 640x480 ULIS micro-bolometer array, a germanium objective and a black body. Using the results of this experiment, we show that calibrated radiometric images can be obtained down to at least 258 K (lower limit of our experiment), and that two calibration points are sufficient to determine the absolute scene temperature with an accuracy better than 1.5 K. An extrapolation to lower temperatures provides an accuracy of about 5 K at 180 K, the lowest temperature the detector can measure. THERMAP spectroscopic capabilites - In order to test the spectroscopic performances of the detector, we added flux attenuating neutral density mid-infrared filters (transmittance: 50%, 10%, 1%) to our experiment. Our results show that we can perform spectroscopic measurements with a spectral resolution R=40-80 in the wavelength range 8-16 ?m for a scene temperature larger than 300 K, the typical surface temperature of a Near Earth Asteroid at 1 AU from the Sun. THERMAP preliminary design - From the above results, we defined a preliminary design for the instrument. THERMAP is a mid-infrared (8-16 ?m) spectro-imager based on two uncooled microbolometer arrays. It is composed of two channels, one for imaging and one for spectroscopy. A flip mirror allows switching between the two channels. Calibration is performed using deep space and two black bodies at known temperature. The design of the THERMAP instrument has a strong heritage from the MERTIS instrument on board Bepi-Colombo [1], which guarantees its feasibility and reliability. Our design is very flexible in term of operations, which is fundamental for a mission to a binary asteroid system (1996 FG3). The THERMAP instrument will be proposed for Marco Polo R and any future space missions to small bodies in the inner solar system.

    Marco Polo is a joint European-Japanese sample return mission to a Near-Earth Object (NEO), selected by ESA for an assessment phase study in the frame of the Cosmic Vision 2015-2025 programme. The primary objective is to return unaltered materials from a primitive Near Earth Object (NEO) to the Earth. NEOs are part of the small body population that represents the primitive leftover building blocks of the Solar System formation process. They offer important clues to the chemical mixture from which the planets formed about 4.6 billion years ago and carry records both of the Solar System's birth/early phases and of the geological evolution of small bodies. This mission will provide the opportunity for detailed laboratory study of the most primitive materials that formed the terrestrial planets and advance our understanding of some of the fundamental issues in the origin and early evolution of the Solar System, the Earth and possibly life itself.

    The main interest of this study is to assess whether uranium deposits located in the San Marcos outcrops (NW of Chihuahua City, Mexico) could be considered as a source of U-isotopes in its surrounding environment. Uranium activity concentrations were determined in biota, ground, and surface water by either alpha or liquid scintillation spectrometries. Major ions were analyzed by ICP-OES in surface water and its suspended matter. For determining uranium activity in biota, samples were divided in parts. The results have shown a possible lixiviation and infiltration of uranium from geological substrate into the ground and surface water, and consequently, a transfer to biota. Calculated annual effective doses by ingestion suggest that U-isotopes in biota could not negligibly contribute to the neighboring population dose. By all these considerations, it is concluded that in this zone there is natural enhancement of uranium in all environmental samples analyzed in the present work. PMID:22536148

    The toxicity of carbon nanotubes (CNTs), a highly promising nanomaterial, is similar to that of asbestos because both types of particles have a fibrous shape and are biopersistent. Here, we investigated the characteristics of macrophage receptor with collagenous structure (MARCO), a membrane receptor expressed on macrophages that recognizes environmental or unopsonized particles, and we assessed whether and how MARCO was involved in cellular uptake of multi-walled CNTs (MWCNTs). MARCO-transfected Chinese hamster ovary (CHO-K1) cells took up polystyrene beads irrespective of the particle size (20 nm–1 ?m). In the culture of MARCO-transfected CHO-K1 cells dendritic structures were observed on the bottom of culture dishes, and the edges of these dendritic structures were continually renewed as the cell body migrated along the dendritic structures. MWCNTs were first tethered to the dendritic structures and then taken up by the cell body. MWCNTs appeared to be taken up via membrane ruffling like macropinocytosis, rather than phagocytosis. The cytotoxic EC{sub 50} value of MWCNTs in MARCO-transfected CHO-K1 cells was calculated to be 6.1 ?g/mL and transmission electron microscopic observation indicated that the toxicity of MWCNTs may be due to the incomplete inclusion of MWCNTs by the membrane structure. -- Highlights: ?Carbon nanotubes (CNTs) were tethered to MARCO in vitro. ?CNTs were taken up rapidly into the cell body via MARCO by membrane ruffling. ?The incomplete inclusion of CNTs by membranes caused cytotoxicity.

    MarcoPolo-R is a sample return mission to a primitive Near-Earth Asteroid (NEA) selected in February 2011 for the Assessment Study Phase at ESA in the framework of ESAfs Cosmic Vision 2 program. MarcoPolo-R is a European-led mission with a proposed NASA contribution. MarcoPolo-R takes advantage of three industrial studies completed as part of the previous Marco Polo mission (see ESA/SRE (2009)3). The aim of the new Assessment Study is to reduce the cost of the mission while maintaining its high science level, on the basis of advanced studies and technologies, as well as optimization of the mission. MarcoPolo-R will rendezvous with a unique kind of target, a primitive binary NEA, scientifically characterize it at multiple scales, and return a unique pristine sample to Earth unaltered by the atmospheric entry process or terrestrial weathering. The baseline target of MarcoPolo-R is the primitive binary NEA (175706) 1996 FG3, which offers a very efficient operational and technical mission profile. A binary target also provides enhanced science return: the choice of this target will allow new investigations to be performed more easily compared to a single object, and also enables investigations of the fascinating geology and geophysics of asteroids that are impossible to obtain from a single object. Precise measurements of the mutual orbit and rotation state of both components can be used to probe higher-level harmonics of the gravitational potential, and therefore the internal structure. A unique opportunity is offered to study the dynamical evolution driven by the YORP/Yarkovsky thermal effects. Possible migration of regolith on the primary from poles to equator allows the increasing maturity of asteroidal regolith with time to be expressed as a latitude-dependent trend, with the most-weathered material at the equator matching what is seen in the secondary. MarcoPolo-R will allow us to study the most primitive materials available to investigate early solar system formation processes. Moreover, MarcoPolo-R will provide a sample from a known target with known geological context. Direct investigation of both the regolith and fresh interior fragments is also impossible by any means other than sample return. The main goal of the MarcoPolo-R mission is to return unaltered NEA material for detailed analysis in ground-based laboratories. The limited sampling provided by meteorites does not offer the most primitive material available in near-Earth space. More primitive material, having experienced less alteration on the asteroid, will be more friable and would not survive atmospheric entry in any discernible amount. Only in the laboratory can instruments with the necessary precision and sensitivity be applied to individual components of the complex mixture of materials that forms an asteroid regolith, to determine their precise chemical and isotopic composition. Such measurements are vital for revealing the evidence of stellar, interstellar medium, pre-solar nebula and parent body processes that are retained in primitive asteroidal material, unaltered by atmospheric entry or terrestrial contamination. It is no surprise therefore that sample return missions are considered a priority by a number of the leading space agencies.

    Background: The Marco Polo-R mission has been selected for the assessment study phase of the ESA M3 missions. This ESA-led sample return mission to the binary asteroid 1996 FG3 (launch window between 2020 and 2024) is proposed with a design that allows it to fit within the pre-defined cost cap of a M-class mission. The binary nature of the target will allow more precise measurements of mass, gravity, and density than for a single object, as well as additional insights into the geology and geophysics of the system. The asteroid has been classified by Binzel et al. [1] as a C-type. It is considered to be a typical example of a primitive object [2]. Dynamically, this is an Apollo asteroid with semimajor axis a of 1.054 AU, eccentricity e of 0.35, and and inclination i of 1.98 degrees. Measurements of the albedo derived from thermal infrared observations give a value of pV = 0.042 (+0.035 -0.017), and a combined diameter of D = 1.84 (+0.56 -0.47) km [3]. The Herschel observations : The MACH-11 (Measurements of 11 Asteroids & Comets) Programme observed this binary asteroid in two occasions in November of 2012. The observations performed had a duration of 0.6 hours with the asteroid pair moving rapidly at 6'/hr thus making removal of the background quite straightforward. The observations were performed in two observing blocks; the first block consisted of a 2 repetition blue/red map, the second block consisted of a 2 repetition green/red map, with the intention to observe the target at different phase angles. Our Results : Our measurements will serve to update the known radiometric properties for this binary asteroid through their inclusion into a thermophysical model (TPM) [4] which has been validated against a large database of asteroids including targets of other spacecraft mission e.g. Lutetia [5], Itokawa [6]. Using existing sets of published thermal observations (Spitzer, TNG NICS), combined with our Herschel observations, applied within this thermophysical model, we will derive the radiometric properties of this target pair. The calculations are to be performed for the full range of possible shape and spin-vector solutions derived from the available sample of visual lightcurve observations, taking into account the implications of the asteroid satellites impact on the derived flux. The output of our model will aid in deriving the asteroids thermal inertia, as well as provide important information on the surface properties of this binary asteroid; important due to their relevance in the preparation of the future Marco Polo-R spacecraft.

    The gill parasite Centrocestus formosanus (Trematoda: Heterophyidae) is an exotic parasite of concern in Texas because it has been shown to infect multiple threatened and endangered fish species. The purpose of this study was to determine if C. formosanus could present a threat to larval anurans, as well as threatened neotenic salamanders endemic to the spring-fed systems of Texas. We exposed adults of the San Marcos salamander Eurycea nana (Caudata: Plethodontidae) and tadpoles of the Rio Grande leopard frog Lithobates berlandieri (Anura: Ranidae) to the cercariae of C. formosanus . The San Marcos salamander showed no signs of metacercarial infection, suggesting that E. nana may be refractory to C. formosanus cercariae. Centrocestus formosanus readily infects the gills of leopard frog tadpoles, but the metacercariae apparently died prior to reaching maturity in our tadpoles. PMID:24303882

    Fish species are suitable biomonitors of radioisotopes in aquatic systems. In the present study, it was made the determination of uranium isotopic contents on fish fillet (Lepomis Cyanellus) from San Marcos dam which is located in uranium mineralized zone. Uranium activity concentrations (AC) in fish samples were obtained on wet weight (ww), using liquid scintillation. 238U and 234U AC in fish fillet ranged from 0.0004 to 0.0167 Bq kg-1, and from 0.0013 to 0.0394 Bq kg-1, respectively. The activity ratio (234U/overflow="scroll">238U) in fish fillet ranged from 2.2 to 8.8. Lepomis cyanellus from San Marcos dam shows bioaccumulation factor (FB) of 0.6 L kg-1. The results suggest that the Lepomis Cyanellus in environments with high U contents tends to have a greater bioaccumulation compared to others.

    The internal structure of small bodies is still poorly known and has never been measured directly. There is no way to determine from ground based observation whether the body is a monolithic piece of rock or a rubble-pile, an aggregate of boulders held together by gravity and how much porosity it contains, both in the form of micro-scale or macro-scale porosity. Knowing this structure is a key point for a better understanding of the asteroid accretion and dynamical evolution. It is the main objective of the FANTINA experience proposed Payload for Marco Polo R CV3 / ESA mission: FANTINA (Marco Polo's Daughter) for Fathom Asteroids Now: Tomography and Imagery of a NEA is to provide measurement capabilities and science data which are not accessible by remote sensing of the asteroid from the Marco-Polo R spacecraft alone and which complement the analysis of the returned samples. The FANTINA payload is a Lander carrying the ASSERT experiment and a complementary payload to be defined: ASSERT is a bistatic CONSERT/Rosetta-like radar to achieve the tomography both in transmission and in reflexion of the asteroid in order to characterise its composition and its heterogeneity from decimetric to global scale. The lander is a long-lived bus in the 10-kg class derived from MASCOT/Hayabusa 2. This paper reviews the science rationale of FANTINA in the context of the Marco Polo R mission to 1996FG3. The surface package concept will be reviewed including the radar tomography principles. So a preliminary design and budget will be done.

    Around the end of XIII century (at the time of young Marco Polo's first trip to China at the court of Khubilai Khan in Khan Baliq) a pocket Bible was delivered by a Franciscan friar to the Mogul Emperor, in the framework of the evangelization program of the Far East. Four centuries later, in 1685, this Bible was rediscovered by the Jesuit Philippe Couplet in the house of a rich Chinese in Nanchin and donated to Cosimo III, Grand Duke of Tuscany. This Bible was recently "unearthed" in the Biblioteca Medicea Laurenziana in Florence, wrapped up in a precious yellow silk cloth, in a rather ruined state. After two years of restoration, the Bible will return to China in 2012 for a celebration of its >700years of life and of its remarkable return trip on the Silk Road. On account of the thinness of the parchment (barely 80?m thickness, the size of each foil being 16.5×11cm) it was widely held that the pages were produced from foetal lambskins. On tiny fragments of the margins of a foil, after several unsuccessful attempts at digesting the vellum, we were able to obtain a tryptic peptide mixture, which, upon mass spectrometry analysis, yielded the identity of 8 unique proteins, belonging to the genus Bos taurus, thus confirming the origin of the vellum from calfskins rather than from foetal lambskins. Our results prove that it is possible to obtain reliable protein extraction and IDs from ancient parchment documents. PMID:22504796

  1. Marcos Zapata's "Last Supper": a feast of European religion and Andean culture.

    In Marcos Zapata's 1753 painting of the Last Supper in Cuzco, Peru, Christian symbolism is filtered through Andean cultural tradition. Zapata was a late member of the Cuzco School of Painting, a group comprised of few European immigrants and handfuls of mestizo and Indian artists. The painters in Cuzco learned mostly from prints of European paintings, and their style tends to blend local culture into the traditional painting of their conquistadors. Imagery was the most successful tool used by the Spaniards in their quest to Christianize the Andean population. By teaching locals to paint Christian subjects, they were able to infuse Christianity into Andean traditions. Zapata's rendering of the Last Supper utilizes this cultural blending while staying true to the Christian symbolism within the subject. Instead of the traditional lamb, Zapata's Last Supper features a platter of cuy, or guinea pig, an Andean delicacy stocked with protein as well as cultural significance. Cuy was traditionally a sacrificial animal at Inca agricultural festivals and in this way it offers poignant parallel to the lamb, as a traditional Christian sacrificial animal. PMID:21568039

  2. Marco Polo: International Small Solar System Body Exploration Mission in 2010's

    NASA Astrophysics Data System (ADS)

    Yano, Hajime

    Since 2000, Japanese scientists and engineers have investigated new generation primitive body missions in the post-Hayabusa era in 2010's. Receiving the Minorbody Exploration Forum Final Report, ISAS established the nation-wide Small Body Exploration Working Group (SBE-WG) in 2004. After the successful exploration of the S-type NEO Itokawa by Hayabusa in 2005, the Hayabusa-2 concept emerged for a C-type asteroid sample return by the original Hayabusa spacecraft system with minor improvements and modifications. In parallel to that effort, the SBE-WG continued to develop the post-Hayabusa mission concept as "Hayabusa Mk-II," a fully model-changed, advanced spacecraft with the sample return capability from the most primitive bodies of the solar system. It is this Hayabusa Mk-II that has became the foundation of the International small body exploration concept "Marco Polo" since 2006. Jointly proposed to the first call of the ESA Cosmic Vision by scientists from Japan, Europe, and the U.S., the Marco Polo concept was selected as one of the M-class mission candidates for the assessment study phase in the fall of 2007. In 2008, the international joint study team has been created and its mission definitions, system requirements, and target selections are currently under the study. The top-level scientific themes are to decode the solar system formation and evolution in the astrobiology and astromineralogy contexts as one of the most important scientific challenges of 2010's. These themes are sub-divided into several objectives to be achieved by both instruments carried onboard the mother spacecraft (MSC), a large lander, or small hopping rovers and returned samples. The initial mission target candicdates include comet-asteroid transition (CAT) objects, D-type asteroids and C-type binary asteroids in near-Earth orbits. In the baseline scenario, a Soyuz launcher provided by ESA will launch the JAXA-made MSC with sampling and other in-situ science instruments provided by both JAXA and ESA, as well as the large European lander and a few small Japanese rovers as possible options, around 2018. In order to reach the CAT object Wilson-Harrington, MSC employs a cluster of improved ion engines inherited from the Hayabusa technology with the Earth gravity assist in the outbound interplanetary cruise. In 2022, the MSC will arrive the target and conduct global mapping and scientific investigation including sampling site selection in a few moths. Then the lander and rovers will be landed on the target surface to conduct cross-scale science being complementary to the MSC instruments and laboratory studies of returned samples. Toward the end of the stay, touch-and-go sequences for surface and possibly sub-surface sample collections will be attempted by taking advantages of operational experiences in the Hayabusa mission. In 2023, the MSC containing the collected samples inside the Earth return capsule will start the inbound cruise back to the Earth while the lander would continue to investigate in-situ the target surface. The sample delivery to the Earth and initial sample analyses, after the planetary quarantine procedure if necessary, will be expected in 2026.

    Marco Polo is a mission to return a sample from a near-Earth object of primitive type (class C or D). It is foreseen as a collaborative effort between the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA). Marco Polo is currently in a Phase-A study (status as of summer 2009). This paper focuses on the scientific requirements provided to the industrial study consortia in Europe as well as the possible mission scenario at the target object in order to achieve the overall mission science objectives. The main scientific reasons for going to a near-Earth object are to understand the initial conditions and evolution history of the solar nebula, to understand how major events (e.g. agglomeration, heating) influence the history of planetesimals, whether primitive class objects contain presolar material, what the organics were in primitive materials, how organics could shed light on the origin of molecules necessary for life, and what the role of impacts by NEOs would be in the origin and evolution of life on Earth.

    This paper presents the sample return mission to a primitive Near-Earth Asteroid (NEA) MarcoPolo-R proposed to the European Space Agency in December 2010. MarcoPolo-R was selected in February 2011 with three other missions addressing different science objectives for the two-year Assessment Phase of the Medium-Class mission competition of the Cosmic Vision 2 program for launch in 2022. The baseline target of MarcoPolo-R is the binary NEA (175706) 1996 FG3, which offers an efficient operational and technical mission profile. A binary target also provides enhanced science return. The choice of a binary target allows several scientific investigations to occur more easily than through a single object, in particular regarding the fascinating geology and geophysics of asteroids. MarcoPolo-R will rendezvous with a primitive, organic-rich NEA, scientifically characterize it at multiple scales, and return a bulk sample to Earth for laboratory analyses. The MarcoPolo-R sample will provide a representative sample from the surface of a known asteroid with known geologic context, and will contribute to the inventory of primitive material that is probably missing from the meteorite collection. The MarcoPolo-R samples will thus contribute to the exploration of the origin of planetary materials and initial stages of habitable planet formation, to the identification and characterization of the organics and volatiles in a primitive asteroid and to the understanding of the unique geomorphology, dynamics and evolution of a binary asteroid that belongs to the Potentially Hazardous Asteroid (PHA) population.

    In order to clarify the historic academic problem of whether or not livestock poisoning in ancient Suzhou of Northwest China, recorded by Marco Polo in 1295, was selenosis, this study deals with the biogeochemistry of selenium in Sunan County in the Hexi Corridor, which is part of ancient Suzhou in China. It was found that quite a number of farm animals had suffered from intoxication and died as a result of grazing poisonous grasses, mostly Oxytropis DC, Stellera chamaejasme, and Achnatheru inebrians. Toxic symptoms of livestock grazing on Oxytropis DC are similar to those of selenium toxicity, for instance, hair loss and hoof lesions as described by Marco Polo. Therefore, we thought that toxic grass, probably Oxytropis DC, led to the intoxication of livestock recorded by Marco Polo. Average Se concentrations in two members of this species were 0.112 +/- 0.038 mg/kg for the root of Oxytropis glabra, 0.102 +/- 0.027 mg/kg for the stem and leaf of Oxytropis glabra, and 0.066 +/- 0.009 mg/kg for Oxytropis ochrocephala. The average soil selenium concentration was 0.205 +/- 0.127 mg/kg on grassland producing Oxytropis glabra and 0.152 +/- 0.024 mg/kg on grassland producing Oxytropis ochrocephala. The average Se concentration in other plants was 0.076 mg/kg in the root of Ephedra monosperma Mey, 0.029 mg/kg in the root of Rheum palmatum, 0.031 mg/kg in the root of Stellera chamaejasme, 0.037 mg/kg in Achnatherum inebrians, and 0.067 mg/kg in forage grass (Achnatherum splendens ohwi). Selenium concentrations in soils and plants in Sunan County are far less than the thresholds causing selenium toxicity in livestock. As a result, this study concludes that the livestock poisoning recorded by Marco Polo in 1295 might not have been selenosis. PMID:18351293

    2014-10-01

    Surface properties of small asteroids are reviewed in this work focusing on microgravity related processes in order to give constrains for targeting sample acquisition by next missions, especially for MarcoPolo-R proposed by ESA. Based on our current knowledge and the planned capabilities of this mission, good chance exists to get answers for the following basic questions. Formation method of nanophase iron and amorphous ingredients in the regolith could be determined, surface particle size and regolith density estimation would also be gained, and with extrapolation to the rest of the surface, knowledge on transport processes, ages and results of cratering under special gravity-strength regime will be improved. Searching for fresh material on asteroid surface in general requires sophisticated effort, as small craters often do not produce much ejecta in microgravity, but the bright annuli around them could be the result of local surface disturbance, while slopes often exhibit fresh material. To identify these locations high albedo, bluer colour and occasionally the depth of 1 ?m absorption band could be useful as they often change parallel to each other. To identify the best area for sample acquisition addresses a strategic question: while smooth terrains with easy navigation and sample acquisition provide strongly weathered fine grains; steeper terrains give access to less weathered, material more representative for the whole asteroid, but navigation and mechanical sampling rise difficulties there.

  10. Las propiedades de las estrellas extrañas en el marco de una nueva ecuación de estado para la materia extraña

    NASA Astrophysics Data System (ADS)

    Lugones, G.; Benvenuto, O. G.

    Se estudian las propiedades generales de las estrellas constituídas por materia extraña (ME) en el marco de una nueva ecuación de estado (EOS) en la que consideramos la masa de los quarks como dependiente del número medio de bariones por unidad de volumen. Se asume esta dependencia de forma que los quarks sean livianos (pesados) a densidades altas (bajas). En esta aproximación, la EOS de la ME es similar a la predicha por el modelo de la Bolsa del MIT, pero es significativamente mas dura a bajas densidades. Esta propiedad modifica las propiedades de las estrellas extrañas en forma notable. Encontramos que, con esta nueva EOS, los objetos pueden ser más masivos que en el caso de la EOS de la bolsa del MIT y que, además, pueden presentar mayores redshifts gravitatorios en hasta un 10%. En el caso de las oscilaciones radiales de estos objetos, calculamos la relación período vs. redshift gravitacional y encontramos una expresión analítica simple para el caso de las oscilaciones de objetos de baja masa. Encontramos que, aún con hipótesis muy diferentes en cuanto a la ecuación de estado de la materia extraña, las propiedades generales de estos objetos no se ve afectada en forma fundamental, y, por lo tanto, no deberían ser muy diferentes de las aquí expuestas.

    The CUC (Close-Up Camera) is part of the selected scientific payload for the MarcoPolo-R mission. It is a powerful, miniaturized, low-power, efficient and highly adaptive system of 820 g, composed of three main parts: a flexible structure focus mechanism allows the acquisition of sharp images of any target from 10 cm to infinity; a colour Active Pixel Sensor with 2652 x 1768 x 3 pixels provides RGB colours keeping the spatial resolution; a high-performance integrated electronics system allows a good flexibility for the operations of the CUC. The CUC is designed to characterize at high resolution and in colour the sampling area and provide the geological context of the sample prior to the sampling operations, which is crucial for the subsequent analysis of the sample back to Earth. The aim is to determine physical key properties of the target's surface, such as grain size distribution, textural, mineralogical, structural, and morphological details in geologic materials, influence of space weathering processes. Thanks to its varying focal length, CUC images can also be acquired before and after the sampling operation: - during the descent, to provide information on the unperturbed regolith surface state of a larger area around the sampling site, - during the ascent, to study how the sampling process will have altered the structural properties of the surface. With its ~14° field of view (diagonal), the CUC can also contribute to the local and global characterization phases, in synergy with the other instruments.

  12. The Marco Polo space mission: sample return from a primitive Near-Earth Object under assessment study in the Cosmic Vision Program of the European Space Agency

    2008-09-01

    Marco Polo is a joint European-Japanese mission study to perform a sample return from a primitive Near-Earth Object (NEO). On October 2007, this mission project passed the first evaluation process in the framework of the ESA Cosmic Vision Programme 2015-2025. The aim of Marco Polo is to reach a primitive NEO, to perform a multiple scale characterization of its physical properties, and to bring samples back to the Earth for detailed analysis in laboratory. The NEO population is composed by asteroids and comets that are thought to be the primitive leftover building blocks of the Solar System formation process. Due to their small sizes, their chemical composition is believed to have kept some memory of the original chemical composition of the solar nebula, contrary to larger planetary bodies who experienced major thermal processes in their interior. They may also carry some important information related to life formation as current exobiological scenarios invoke an exogeneous delivery of organic matter to the early Earth for the origin of terrestrial life. Finally, the hazard caused by these small bodies needs mitigation strategies which efficiency relies on our understanding of their physical properties. Marco Polo will give us the first opportunity for detailed laboratory study of the most primitive materials. This sample return space mission has therefore the potential to revolutionize our understanding of primitive materials, essential to undestand the conditions for planet formation and emergency of life. Current mission studies and expected results will be presented and discussed.

  14. New observations of asteroid (175706) 1996 FG3, primary target of the ESA Marco Polo-R mission

    2011-06-01

    Context. Near-Earth asteroid (175706) 1996 FG3 is the primary target of the ESA Marco Polo-R mission, which was selected for the assessment study phase of ESA M3 missions. This is a primitive (C-type), binary asteroid that will allow new research to be performed. The primary is a rapidly rotating (3.6 h) small asteroid (1.4 km diameter) that is almost spherical and has a satellite of ~400 m. Aims: We analyse new ground-based spectroscopic data of 1996 FG3 to help us characterise its surface composition and prepare for the mission. Methods: We obtained a near-infrared spectrum covering the range 0.8-2.5 ?m, using the camera-spectrograph NICS at the 3.6 m telescope TNG (Telescopio Nazionale Galileo), located at "El Roque de los Muchachos" Observatory on La Palma, Spain. We combine our near-infrared spectrum with previously published data, and compare all the available spectra of this asteroid with the spectra of meteorites to constrain the mineralogy of the asteroid. Results: Our spectrum of FG3 differs remarkably from previously published ones. Spectral classification performed using the complete visible and near-infrared range yields more than one result, varying from C to Xk types. However, all the possible spectral types indicate that this asteroid is a primitive object. The comparison with meteorites behaves in the same way, providing several good matches to our new near-infrared spectrum (CM2 carbonaceous chondrite, and L6 and H4 ordinary chondrites), and only one match in the case of the previously published spectra (weakly shocked H4 ordinary chondrite, dark vein). The albedo of the asteroid (~0.04), is typical of a primitive object, and is consistent with the reflectance value at 0.55 ?m of the CM2 carbonaceous chondrite. Further observations will be essential to help us characterise more clearly the mineralogy of this asteroid.

    We present a refinement of our model describing the association between enzyme activity and histopathological lesions in the catfish, Sciades herzbergii from a polluted port. The fish were sampled from a port known to be contaminated with heavy metals and organic compounds and from a natural reserve in São Marcos Bay, Brazil. Two biomarkers, hepatic glutathione S-transferase (GST) activity and histopathological lesions, in gills and liver tissue were measured. The values for GST activity were modeled with the occurrence of branchial and hepatic lesions by fitting a third-order polynomial. Results from the mathematical model indicate that GST activity has a strong polynomial relationship with the occurrence of branchial and hepatic lesions in both wet and the dry seasons but only at the polluted port site. The model developed in this study indicates that branchial and hepatic lesions are initiated when GST activity reaches 2.17 ?mol min(-1) mg protein(-1). Beyond this limit, GST activity decreased to very low levels and irreversible histopathological lesions occurred. This mathematical model based on two biomarkers (histopathological lesions and enzyme activity) in catfish provides a realistic approach to analyze stress induced by contaminants. PMID:25227683

Samples are obtained from the San Marcos arch, south-central Texas, at depths ranging from outcrop to 15,000 ft. Samples from above the depth of intense illitization and feldspar reactions (about 10,000 ft) have whole-rock Nd model ages of about 1,500-1,400 Ma, whereas samples buried deeper than 13,000 ft have Nd model ages of about 1,700-1,500 Ma. The similar depositional age of all samples makes change in provenance an unlikely cause of the variation. Diagenetic modification is the only reasonable explanation for the observed differences. Sm and Nd reservoirs within the shale change considerably with progressive diagenesis. Outcrop samples contain subequal concentrations of Sm and Nd in the acid-soluble and silicate fractions. The acid-soluble reservoir in deeper samples contains progressively less Sm and Nd and higher Sm/Nd ratios. In all samples, the acid-soluble Nd is more radiogenic than the Nd in the corresponding silicate fraction; the difference between the two reservoirs increases with depth. Preferential loss of Nd relative to Sm in the silicate reservoir during diagenetic crystallization of illite and albite is the most likely explanation for the observed trend in Nd model age. These data imply that the earlier assumption that no fractionation takes place in the Sm-Nd system during diagenesis is incorrect.

  10. The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

    Hizer, Suzanne Elizabeth

    Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI sessions and discussed given the theoretical frameworks of Bandura's concept of self-efficacy and learning environment activities that embody constructivist principles.

    We report Arecibo (2380 MHz), 13-cm) and Goldstone (8560 MHz, 3.5-cm) delay-Doppler radar observations of binary near-Earth asteroid and Marco Polo-R mission target (175706) 1996 FG3 that were obtained on nine dates between November 6-December 17, 2011. The images achieve resolutions as fine as 75 m in range and place hundreds of pixels on the primary. The images provide thorough rotational coverage by the primary and reveal a rounded, slightly elongated object with a visible extent of 0.9 km. If the visible extent is about ½ of the actual extent, which would be true for a sphere, then the equatorial diameter is about 1.8 km. The primary has features along its leading edge that resemble the signature of the pronounced ridge on the equator of binary asteroid (66391) 1999 KW4. The images sample a wide range of orbital positions by the secondary, resolve it in range and Doppler frequency, show that it is elongated and roughly 500 m in diameter, and suggest that its rotation is synchronous (or nearly so) with the orbital period of 16.1 h estimated by Scheirich and Pravec (2009, Icarus 200, 531-547). We observe a maximum range separation of 2.5 km that, combined with the nearly circular eccentricity found by Scheirich and Pravec from inversion of lightcurves, establishes a lower bound on the semimajor axis. 1996 FG3 has a circular polarization ratio SC/OC = 0.34±0.02 that is comparable to that of 25143 Itokawa (0.28±0.04), suggesting similar degrees of near-surface roughness. The radar data will yield a 3D model of the primary, possibly a coarse-resolution model of the secondary, more precise orbit fitting, and estimates of the system’s mass and bulk density.

These techniques were developed to predict the Solar Maximum Mission (SMM) spacecraft orbit, which is decaying due to atmospheric drag, with reentry predicted to occur before the end of 1989. Lifetime predictions were also performed for the Long Duration Exposure Facility (LDEF), which

    The hydrated groups of carbonaceous chondrites (hereafter CCs) exhibit different degrees of aqueous alteration. Primary minerals were transformed in their parent bodies by the action of the water. Most of the water was probably accreted as ice or bounded in hydrated minerals. Moderate heating associated with residual radioactivity or collisional compaction released that water to soak temporarily the materials forming these asteroids. Evidence for static and dynamic aqueous mineral products has been described [1, 2], at the same time that the different degrees of alteration exhibited for members of the CM group were characterized [3, 4]. We apply here a new IR spectroscopic technique that allows to assess the amount of adsorbed water present in minerals forming carbonaceous chondrites.

    We report the results from a series of four controlled trials which evaluate efficacy, effectiveness, and implementation of interventions for smokers, and then discuss diffusion of our program in feasibility studies both nationally in Australia and internationally. In our first study we reported that when general practitioners delivered moderately brief advice to smokers, they have a 36% abstinence rate at three years. In the second study we found that doctors achieve a 12% abstinence at one year after giving minimal advice to patients, and when using a more involved intervention, quit rates of just less than 20% at one year. In the third and fourth studies of utilization of the smoking cessation program we report that reinforcement contact following a 2-hour training workshop increased doctors' use of a smoking cessation program at 6 months compared to no contact. The challenge of translating research findings into practice for the benefit of doctors in Australia as well as in a low-income country such as China, is described in two feasibility studies. Over the past 11 years we have disseminated the program nationally in Australia, and over 4500 doctors have been trained. Diffusion theory provides a useful model which has guided us in our implementation efforts in Australia and is being used to allow us to introduce the smoking cessation intervention for Chinese doctors to use.

    This COCORP deep seismic survey provides a comprehensive image of the southeast-Texas part of the Gulf passive margin and its accreted Ouachita arc foundation. Beneath the updip limit of the Cenozoic sediment wedge, a prominent antiformal structure is imaged within the interior zone of the buried late Paleozoic Ouachita orogen. The structure appears to involve Precambrian Grenville basement. The crest of the antiform is coincident with the Cretaceous-Tertiary Luling-Mexia-Talco fault zone. Some of these faults dip to the northwest, counter to the general regional pattern of down-to-the-basin faulting, and appear to sole into the top of the antiform, suggesting that the Ouachita structure has been reactivated as a hingeline to the subsiding passive margin. The antiform may be tied via this fault system and the Ouachita gravity gradient to the similar Devils River, Waco, and Benton uplifts, interpreted as Precambrian basement-cored massifs. Above the Paleozoic sequence, a possible rift-related graben is imaged near the updip limit of Jurassic salt. Paleoshelf edges of the major Tertiary depositional sequences are marked by expanded sections disrupted by growth faults and shale diapirs. Within the Wilcox Formation, the transect crosses the mouth of the 900-m-deep Yoakum Canyon, a principal pathway of sediment delivery from the Laramide belt to the Gulf. Beneath the Wilcox, the Comanchean (Lower Cretaceous) shelf edge, capped by the Stuart City reef, is imaged as a pronounced topographic break onlapped by several moundy sediment packages. Because this segment of the line parallels strike, the topographic break may be interpreted as a 2,000-m-deep embayment in the Cretaceous shelf-edge, and possibly a major submarine canyon older and deeper than the Yoakum Canyon.

    Transgenic potato plants (SS2 and SS4) that overexpressed a chloroplastic copper/zinc superoxide dismutase lily gene were utilized as an H(2)O(2)-inducible system in order to study the role of H(2)O(2) as a signaling molecule in the biosynthesis of ethylene. SS2 and SS4 plants grown in vitro under sealed microenvironment (SME) conditions displayed anomalous phenotypes including reduction of stem elongation, radial stem growth, and promotion of root hair formation in the generated root, which were similar to ethylene-induced responses. In addition, SS4 plants showed severe vitrification in developing leaves and elevated ethylene production under SME conditions. After the ethylene action inhibitor AgNO(3), 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase (ACO) inhibitor CoCl(2), and ACC synthase inhibitor L -aminoethoxyvinylglycine were added to the growth media, the anomalous phenotypes in SS4 plants reverted to their normal phenotype with a concurrent decrease in ethylene production. Northern blot analysis showed that ACO transcripts in SS4 plants were constantly at high levels under normal and SME conditions, indicating that a high level of H(2)O(2) in SS4 plants up-regulates ACO transcripts. Moreover, the direct treatment of H(2)O(2) in potato plants confirmed the elevated expression of the ACO gene. Taken together, these data suggest that the high concentration of H(2)O(2) in transgenic potato plants stimulates ethylene biosynthesis by activating ACO gene expression. PMID:18273621
