    Beschreibung: The bloom-forming cyanobacteria Trichodesmium contribute up to 30% to the total fixed nitrogen in the global oceans and thereby drive substantial productivity. On an expedition in the Gulf of Mexico, we observed and sampled surface slicks, some of which included dense blooms of Trichodesmium erythraeum. These bloom samples contained abundant and atypical free fatty acids, identified here as 2-methyldecanoic acid and 2-methyldodecanoic acid. The high abundance and unusual branching pattern of these compounds suggest that they may play a specific role in this globally important organism.

    Ancient aqueous environments at Endeavour crater, Mars (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-01-25
    Beschreibung: Opportunity has investigated in detail rocks on the rim of the Noachian age Endeavour crater, where orbital spectral reflectance signatures indicate the presence of Fe(+3)-rich smectites. The signatures are associated with fine-grained, layered rocks containing spherules of diagenetic or impact origin. The layered rocks are overlain by breccias, and both units are cut by calcium sulfate veins precipitated from fluids that circulated after the Endeavour impact. Compositional data for fractures in the layered rocks suggest formation of Al-rich smectites by aqueous leaching. Evidence is thus preserved for water-rock interactions before and after the impact, with aqueous environments of slightly acidic to circum-neutral pH that would have been more favorable for prebiotic chemistry and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arvidson, R E -- Squyres, S W -- Bell, J F 3rd -- Catalano, J G -- Clark, B C -- Crumpler, L S -- de Souza, P A Jr -- Fairen, A G -- Farrand, W H -- Fox, V K -- Gellert, R -- Ghosh, A -- Golombek, M P -- Grotzinger, J P -- Guinness, E A -- Herkenhoff, K E -- Jolliff, B L -- Knoll, A H -- Li, R -- McLennan, S M -- Ming, D W -- Mittlefehldt, D W -- Moore, J M -- Morris, R V -- Murchie, S L -- Parker, T J -- Paulsen, G -- Rice, J W -- Ruff, S W -- Smith, M D -- Wolff, M J -- New York, N.Y. -- Science. 2014 Jan 24;343(6169):1248097. doi: 10.1126/science.1248097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, Washington University in Saint Louis, St. Louis, MO 63130, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24458648" target="_blank"〉PubMed〈/a〉

    Dust and biological aerosols from the Sahara and Asia influence precipitation in the western U.S (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-03-02
    Beschreibung: Winter storms in California's Sierra Nevada increase seasonal snowpack and provide critical water resources and hydropower for the state. Thus, the mechanisms influencing precipitation in this region have been the subject of research for decades. Previous studies suggest Asian dust enhances cloud ice and precipitation, whereas few studies consider biological aerosols as an important global source of ice nuclei (IN). Here, we show that dust and biological aerosols transported from as far as the Sahara were present in glaciated high-altitude clouds coincident with elevated IN concentrations and ice-induced precipitation. This study presents the first direct cloud and precipitation measurements showing that Saharan and Asian dust and biological aerosols probably serve as IN and play an important role in orographic precipitation processes over the western United States.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Creamean, Jessie M -- Suski, Kaitlyn J -- Rosenfeld, Daniel -- Cazorla, Alberto -- DeMott, Paul J -- Sullivan, Ryan C -- White, Allen B -- Ralph, F Martin -- Minnis, Patrick -- Comstock, Jennifer M -- Tomlinson, Jason M -- Prather, Kimberly A -- New York, N.Y. -- Science. 2013 Mar 29;339(6127):1572-8. doi: 10.1126/science.1227279.

    Foreword and Acknowledgements (2012)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: This is the first volume of an international scientific journal that is dedicated to issues of geoethics and geological culture. Its goal is to inform the Italian and international scientific communities about what emerged at the GeoItalia 2011 conference, attended by not only Italian geoscientists. At this conference, the geoscientists questioned their role in society and the responsibilities that they have to assume as scholars of the planet Earth and experts of the territory. They highlighted the need for rediscovery of the cultural values of geology as a science that can contribute to the construction of correct social knowledge, and the need to be aware that geoethics cannot exist without a real awareness among geoscientists of the cultural value of the Earth sciences.

    Geoethics and geological culture: awareness, responsibility and challenges (2012)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The international debate in the field of geoethics focuses on some of the most important environmental emergencies, while highlighting the great responsibilities of geoscientists, whatever field they work in, and the important social, cultural and economic repercussions that their choices can have on society. The GeoItalia 2009 and 2011 conferences that were held in Rimini and Turin, respectively, and were organized by the Italian Federation of Earth Science, were two important moments for the promotion of geoethics in Italy. They were devoted to the highlighting of how, and with what tools and contents, can the geosciences contribute to the cultural renewal of society. They also covered the active roles of geoscientists in the dissemination of scientific information, contributing in this way to the correct construction of social knowledge. Geology is culture, and as such it can help to dispel misconceptions and cultural stereotypes that concern natural phenomena, disasters, resources, and land management. Geological culture consists of methods, goals, values, history, ways of thinking about nature, and specific sensitivity for approaching problems and their solutions. So geology has to fix referenced values, as indispensable prerequisites for geoethics. Together, geological culture and geoethics can strengthen the bond that joins people to their territory, and can help to find solutions and answers to some important challenges in the coming years regarding natural risks, resources, and climate change. Starting from these considerations, we stress the importance of establishing an ethical criterion for Earth scientists, to focus attention on the issue of the responsibility of geoscientists, and the need to more clearly define their scientific identity and the value of their specificities.

    A Hippocratic Oath for geologists? (2012)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: We argue here that the introduction of an ethical code of conduct that follows the example of the Hippocratic Oath of physicians will help geologists to acquire binding awareness of their professional and social responsibilities. The ethical behavior and obligations of modern geologists involve, but are not limited to, the following issues: correct land/ environment use and management; respect of truth and science; and protection of the Earth systems, on both the local and global scales, and therefore, of our well-being. We believe that for geoligists, the explicit acceptance of an ethical code will help to promote: (i) an awareness of their social role, expertise and sense of belonging to a professional community; (ii) an understanding of the expectations of citizens and society; and (iii) cultural growth, with better use of research and implementation of scientific and professional skills. All this should enhance the public recognition of the social mission of geologists, which is essential for the well-being of society. Therefore, we suggest that like in the majority of medical schools, ethical training should be a part of the university curriculum for students in geology.

    Trophic structure and community stability in an overfished ecosystem (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-07-22
    Beschreibung: Since the collapse of the pelagic fisheries off southwest Africa in the late 1960s, jellyfish biomass has increased and the structure of the Benguelan fish community has shifted, making the bearded goby (Sufflogobius bibarbatus) the new predominant prey species. Despite increased predation pressure and a harsh environment, the gobies are thriving. Here we show that physiological adaptations and antipredator and foraging behaviors underpin the success of these fish. In particular, body-tissue isotope signatures reveal that gobies consume jellyfish and sulphidic diatomaceous mud, transferring "dead-end" resources back into the food chain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Utne-Palm, Anne C -- Salvanes, Anne G V -- Currie, Bronwen -- Kaartvedt, Stein -- Nilsson, Goran E -- Braithwaite, Victoria A -- Stecyk, Jonathan A W -- Hundt, Matthias -- van der Bank, Megan -- Flynn, Bradley -- Sandvik, Guro K -- Klevjer, Thor A -- Sweetman, Andrew K -- Bruchert, Volker -- Pittman, Karin -- Peard, Kathleen R -- Lunde, Ida G -- Strandabo, Ronnaug A U -- Gibbons, Mark J -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):333-6. doi: 10.1126/science.1190708.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Bergen, Bergen, Norway. anne.palm@bio.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20647468" target="_blank"〉PubMed〈/a〉

    Blackening of Pompeian Cinnabar paintings: X-ray micro-spectroscopy analysis (2007)
    American Chemical Society
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: Red Pompeian paintings, very famous for their deep intensity, are currently suffering from darkening. The origins of this darkening degradation are not clearly identified yet and remain a major issue for curators. In the specific case of cinnabar (HgS)-based red pigment, a photoinduced conversion into black metacinnabar is usually suspected. This work is focused on the blackening of red cinnabar paintings coated on a sparry calcite mortar. Different samples exhibiting different levels of degradation were selected upon visual observations and analyzed by synchrotron-based microanalytical techniques. Atomic and molecular compositions of the different debased regions revealed two possible degradation mechanisms. On one hand, micro X-ray fluorescence elemental maps show peculiar distributions of chlorine and sulfur. On the other hand, X-ray absorption spectroscopy performed at both Cl and S K-edges confirms the presence of characteristic degradation products: (i) Hg- Cl compounds (e.g., corderoite, calomel, and terlinguaite), which may result from the reaction with exogenous NaCl, in gray areas; (ii) gypsum, produced by the calcite sulfation, in black coatings. Metacinnabar is never detected. Finally, a cross section was analyzed to map the in-depth alteration gradient. Reduced and oxidized sulfur distributions reveal that the sulfated black coating consists of a 5-ím-thick layer covering intact cinnabar.

    Abundance of cellular material and proteins in the atmosphere (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-04-02
    Beschreibung: Suspended atmospheric particles play a crucial role in any global climate scenario: They can both enforce and suppress radiative forcing. In developing climate modeling further, a deeper understanding of atmospheric aerosol is needed. Because of extreme local and temporal variations, proper incorporation of aerosols into models requires modeling of the aerosol itself. It turns out that cellular material and proteins compose up to 25% of the atmospheric aerosol. Consequently, the source strength of the biogenic aerosol in general must be corrected and should be estimated on the order of other major aerosol sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jaenicke, Ruprecht -- New York, N.Y. -- Science. 2005 Apr 1;308(5718):73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Physik der Atmosphare, Universitat Mainz, 55099 Mainz, Germany. jaenicke@uni-mainz.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15802596" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 2004-10-30
    Beschreibung: We report a detection of methane in the martian atmosphere by the Planetary Fourier Spectrometer onboard the Mars Express spacecraft. The global average methane mixing ratio is found to be 10 +/- 5 parts per billion by volume (ppbv). However, the mixing ratio varies between 0 and 30 ppbv over the planet. The source of methane could be either biogenic or nonbiogenic, including past or present subsurface microorganisms, hydrothermal activity, or cometary impacts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Formisano, Vittorio -- Atreya, Sushil -- Encrenaz, Therese -- Ignatiev, Nikolai -- Giuranna, Marco -- New York, N.Y. -- Science. 2004 Dec 3;306(5702):1758-61.

    Historical overfishing and the recent collapse of coastal ecosystems (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-07-28
    Beschreibung: Ecological extinction caused by overfishing precedes all other pervasive human disturbance to coastal ecosystems, including pollution, degradation of water quality, and anthropogenic climate change. Historical abundances of large consumer species were fantastically large in comparison with recent observations. Paleoecological, archaeological, and historical data show that time lags of decades to centuries occurred between the onset of overfishing and consequent changes in ecological communities, because unfished species of similar trophic level assumed the ecological roles of overfished species until they too were overfished or died of epidemic diseases related to overcrowding. Retrospective data not only help to clarify underlying causes and rates of ecological change, but they also demonstrate achievable goals for restoration and management of coastal ecosystems that could not even be contemplated based on the limited perspective of recent observations alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jackson, J B -- Kirby, M X -- Berger, W H -- Bjorndal, K A -- Botsford, L W -- Bourque, B J -- Bradbury, R H -- Cooke, R -- Erlandson, J -- Estes, J A -- Hughes, T P -- Kidwell, S -- Lange, C B -- Lenihan, H S -- Pandolfi, J M -- Peterson, C H -- Steneck, R S -- Tegner, M J -- Warner, R R -- New York, N.Y. -- Science. 2001 Jul 27;293(5530):629-37.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093-0244, USA. jbcj@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11474098" target="_blank"〉PubMed〈/a〉

    Search for past life on Mars: possible relic biogenic activity in martian meteorite ALH84001 (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1996-08-16
    Beschreibung: Fresh fracture surfaces of the martian meteorite ALH84001 contain abundant polycyclic aromatic hydrocarbons (PAHs). These fresh fracture surfaces also display carbonate globules. Contamination studies suggest that the PAHs are indigenous to the meteorite. High-resolution scanning and transmission electron microscopy study of surface textures and internal structures of selected carbonate globules show that the globules contain fine-grained, secondary phases of single-domain magnetite and Fe-sulfides. The carbonate globules are similar in texture and size to some terrestrial bacterially induced carbonate precipitates. Although inorganic formation is possible, formation of the globules by biogenic processes could explain many of the observed features, including the PAHs. The PAHs, the carbonate globules, and their associated secondary mineral phases and textures could thus be fossil remains of a past martian biota.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKay, D S -- Gibson, E K Jr -- Thomas-Keprta, K L -- Vali, H -- Romanek, C S -- Clemett, S J -- Chillier, X D -- Maechling, C R -- Zare, R N -- New York, N.Y. -- Science. 1996 Aug 16;273(5277):924-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉NASA Lyndon B.

    Beschreibung: Eleven taxa (including eight heretofore undescribed species) of cellularly preserved filamentous microbes, among the oldest fossils known, have been discovered in a bedded chert unit of the Early Archean Apex Basalt of northwestern Western Australia. This prokaryotic assemblage establishes that trichomic cyanobacterium-like microorganisms were extant and morphologically diverse at least as early as approximately 3465 million years ago and suggests that oxygen-producing photoautotrophy may have already evolved by this early stage in biotic history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schopf, J W -- New York, N.Y. -- Science. 1993 Apr 30;260:640-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Space Sciences, University of California, Los Angeles 90024, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11539831" target="_blank"〉PubMed〈/a〉

    The antiquity of oxygenic photosynthesis: evidence from stromatolites in sulphate-deficient Archaean lakes (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-01-03
    Beschreibung: The Tumbiana Formation, about 2700 million years old, was largely deposited in ephemeral saline lakes, as judged by the unusual evaporite paragenesis of carbonate and halite with no sulfate. Stromatolites of diverse morphology occur in the lacustrine sediments, some with palimpsest fabrics after erect filaments. These stromatolites were probably accreted by phototropic microbes that, from their habitat in shallow isolated basins with negligible sulfate concentrations, almost certainly metabolized by ozygenic photosynthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buick, R -- New York, N.Y. -- Science. 1992 Jan 3;255(5040):74-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Botanical Museum, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11536492" target="_blank"〉PubMed〈/a〉

    Male-killing bacteria in a parasitic wasp (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-02-28
    Beschreibung: A rod-shaped bacterium has been isolated that kills male eggs of the wasp Nasonia vitripennis, a pupal parasite of flies. Only some wasps of this species express this son-killer trait, and these wasps have bacterial infections in various organs. The bacterium was isolated from son-killer wasp tissue and from the hemolymph of fly pupae parasitized by wasps expressing the son-killer trait. Bacteria are apparently transferred to parasitized fly pupae during wasp oviposition, and developing wasp offspring are subsequently infected perorally. Sex-ratio distortion by microorganisms is found in a variety of plants and animals. The infectious peroral transmission of this trait variety of plants and animals. The infectious peroral transmission of this trait is in contrast to the typical pattern of cytoplasmic inheritance of sex-ratio distortion in these other systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werren, J H -- Skinner, S W -- Huger, A M -- 5 T32 6MO7131/PHS HHS/ -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):990-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945814" target="_blank"〉PubMed〈/a〉

    Gram-positive bacteria: possible photosynthetic ancestry (1985)

    Beschreibung: A 16S ribosomal RNA gene has been sequenced from Heliobacterium chlorum, the recently discovered photosynthetic bacterium that contains a novel form of chlorophyll. Comparisons with other 16S ribosomal RNA sequences show that the organism belongs to the Gram-positive bacteria (one of ten eubacterial "phyla")--more precisely to the so-called low G + C (G, guanine; C, cytosine) subdivision thereof. This brings to five the number of such phyla that contain photosynthetic species, the other four being the purple bacteria and relatives, the green sulfur bacteria, the green nonsulfur bacteria, and the cyanobacteria. The finding suggests that Gram-positive bacteria may be of photosynthetic ancestry, and it strengthens the case for a common photosynthetic ancestry for all eubacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woese, C R -- Debrunner-Vossbrinck, B A -- Oyaizu, H -- Stackebrandt, E -- Ludwig, W -- New York, N.Y. -- Science. 1985;229:762-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Development, University of Illinois, Urbana 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11539659" target="_blank"〉PubMed〈/a〉
