    Proterozoic ocean chemistry and evolution: a bioinorganic bridge? (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-08-17
    Description: Recent data imply that for much of the Proterozoic Eon (2500 to 543 million years ago), Earth's oceans were moderately oxic at the surface and sulfidic at depth. Under these conditions, biologically important trace metals would have been scarce in most marine environments, potentially restricting the nitrogen cycle, affecting primary productivity, and limiting the ecological distribution of eukaryotic algae. Oceanic redox conditions and their bioinorganic consequences may thus help to explain observed patterns of Proterozoic evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anbar, A D -- Knoll, A H -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1137-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Environmental Sciences, University of Rochester, Rochester, NY 14627, USA. anbar@earth.rochester.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12183619" target="_blank"〉PubMed〈/a〉

    Dissociative recombination of HD+ in selected vibrational quantum states (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-07-04
    Description: Rate coefficients for dissociative recombination of HD+ in selected vibrational states have been measured by a combination of two molecular fragment imaging methods by using the heavy-ion storage ring technique. Recombination fragment imaging yields state-to-state reaction rates. These rates are converted to rate coefficients by using vibrational level populations of the stored ion beam, derived from nuclear coordinate distributions measured on extracted ions. The results show strongly increasing rate coefficients for high vibrational excitation, where additional dissociation routes open up, in agreement with a theoretical calculation. Very low rate coefficients are found for certain, isolated vibrational states.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amitay -- Baer -- Dahan -- Knoll -- Lange -- Levin -- Schneider -- Schwalm -- Suzor-Weiner -- Vager -- Wester -- Wolf -- Zajfman -- New York, N.Y. -- Science. 1998 Jul 3;281(5373):75-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Z.

    Early animal evolution: emerging views from comparative biology and geology (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-06-26
    Description: The Cambrian appearance of fossils representing diverse phyla has long inspired hypotheses about possible genetic or environmental catalysts of early animal evolution. Only recently, however, have data begun to emerge that can resolve the sequence of genetic and morphological innovations, environmental events, and ecological interactions that collectively shaped Cambrian evolution. Assembly of the modern genetic tool kit for development and the initial divergence of major animal clades occurred during the Proterozoic Eon. Crown group morphologies diversified in the Cambrian through changes in the genetic regulatory networks that organize animal ontogeny. Cambrian radiation may have been triggered by environmental perturbation near the Proterozoic-Cambrian boundary and subsequently amplified by ecological interactions within reorganized ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knoll, A H -- Carroll, S B -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2129-37.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, 26 Oxford Street, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381872" target="_blank"〉PubMed〈/a〉

    A bangiophyte red alga from the Proterozoic of arctic Canada (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-10-05
    Description: Silicified peritidal carbonate rocks of the 1250- to 750-million-year-old Hunting Formation, Somerset Island, arctic Canada, contain fossils of well-preserved bangiophyte red algae. Morphological details, especially the presence of multiseriate filaments composed of radially arranged wedge-shaped cells derived by longitudinal divisions from disc-shaped cells in uniseriate filaments, indicate that the fossils are related to extant species in the genus Bangia. Such taxonomic resolution distinguishes these fossils from other pre-Ediacaran eukaryotes and contributes to growing evidence that multicellular algae diversified well before the Ediacaran radiation of large animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butterfield, N J -- Knoll, A H -- Swett, K -- New York, N.Y. -- Science. 1990 Oct 5;250:104-7.〈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/11538072" target="_blank"〉PubMed〈/a〉

    The early evolution of eukaryotes: a geological perspective (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-01
    Description: Molecular phylogenies of eukaryotic organisms imply patterns of biological and environmental history that can be tested against the geological record. As predicted by sequence comparisons, Precambrian rocks show evidence of episodic increases in biological diversity and atmospheric oxygen concentrations. Nonetheless, complete integration of the two records remains elusive and may require that the earliest macroscopic organisms be recognized as extinct experiments in eukaryotic multicellularity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knoll, A H -- New York, N.Y. -- Science. 1992 May 1;256(5057):622-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Harvard University, Botanical Museum, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1585174" target="_blank"〉PubMed〈/a〉

    Ferruginous conditions dominated later neoproterozoic deep-water chemistry (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-19
    Description: Earth's surface chemical environment has evolved from an early anoxic condition to the oxic state we have today. Transitional between an earlier Proterozoic world with widespread deep-water anoxia and a Phanerozoic world with large oxygen-utilizing animals, the Neoproterozoic Era [1000 to 542 million years ago (Ma)] plays a key role in this history. The details of Neoproterozoic Earth surface oxygenation, however, remain unclear. We report that through much of the later Neoproterozoic (〈742 +/- 6 Ma), anoxia remained widespread beneath the mixed layer of the oceans; deeper water masses were sometimes sulfidic but were mainly Fe2+-enriched. These ferruginous conditions marked a return to ocean chemistry not seen for more than one billion years of Earth history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Canfield, Donald E -- Poulton, Simon W -- Knoll, Andrew H -- Narbonne, Guy M -- Ross, Gerry -- Goldberg, Tatiana -- Strauss, Harald -- New York, N.Y. -- Science. 2008 Aug 15;321(5891):949-52. doi: 10.1126/science.1154499.

    Exploration of Victoria crater by the Mars rover Opportunity (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-23
    Description: The Mars rover Opportunity has explored Victoria crater, an approximately 750-meter eroded impact crater formed in sulfate-rich sedimentary rocks. Impact-related stratigraphy is preserved in the crater walls, and meteoritic debris is present near the crater rim. The size of hematite-rich concretions decreases up-section, documenting variation in the intensity of groundwater processes. Layering in the crater walls preserves evidence of ancient wind-blown dunes. Compositional variations with depth mimic those approximately 6 kilometers to the north and demonstrate that water-induced alteration at Meridiani Planum was regional in scope.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Squyres, S W -- Knoll, A H -- Arvidson, R E -- Ashley, J W -- Bell, J F 3rd -- Calvin, W M -- Christensen, P R -- Clark, B C -- Cohen, B A -- de Souza, P A Jr -- Edgar, L -- Farrand, W H -- Fleischer, I -- Gellert, R -- Golombek, M P -- Grant, J -- Grotzinger, J -- Hayes, A -- Herkenhoff, K E -- Johnson, J R -- Jolliff, B -- Klingelhofer, G -- Knudson, A -- Li, R -- McCoy, T J -- McLennan, S M -- Ming, D W -- Mittlefehldt, D W -- Morris, R V -- Rice, J W Jr -- Schroder, C -- Sullivan, R J -- Yen, A -- Yingst, R A -- New York, N.Y. -- Science. 2009 May 22;324(5930):1058-61. doi: 10.1126/science.1170355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Astronomy, Space Sciences Building, Cornell University, Ithaca, NY 14853, USA. squyres@astro.cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19461001" target="_blank"〉PubMed〈/a〉

    Nanoscale three-dimensional patterning of molecular resists by scanning probes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-24
    Description: For patterning organic resists, optical and electron beam lithography are the most established methods; however, at resolutions below 30 nanometers, inherent problems result from unwanted exposure of the resist in nearby areas. We present a scanning probe lithography method based on the local desorption of a glassy organic resist by a heatable probe. We demonstrate patterning at a half pitch down to 15 nanometers without proximity corrections and with throughputs approaching those of Gaussian electron beam lithography at similar resolution. These patterns can be transferred to other substrates, and material can be removed in successive steps in order to fabricate complex three-dimensional structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pires, David -- Hedrick, James L -- De Silva, Anuja -- Frommer, Jane -- Gotsmann, Bernd -- Wolf, Heiko -- Despont, Michel -- Duerig, Urs -- Knoll, Armin W -- New York, N.Y. -- Science. 2010 May 7;328(5979):732-5. doi: 10.1126/science.1187851.

    Genome expansion and gene loss in powdery mildew fungi reveal tradeoffs in extreme parasitism (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-12-15
    Description: Powdery mildews are phytopathogens whose growth and reproduction are entirely dependent on living plant cells. The molecular basis of this life-style, obligate biotrophy, remains unknown. We present the genome analysis of barley powdery mildew, Blumeria graminis f.sp. hordei (Blumeria), as well as a comparison with the analysis of two powdery mildews pathogenic on dicotyledonous plants. These genomes display massive retrotransposon proliferation, genome-size expansion, and gene losses. The missing genes encode enzymes of primary and secondary metabolism, carbohydrate-active enzymes, and transporters, probably reflecting their redundancy in an exclusively biotrophic life-style. Among the 248 candidate effectors of pathogenesis identified in the Blumeria genome, very few (less than 10) define a core set conserved in all three mildews, suggesting that most effectors represent species-specific adaptations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spanu, Pietro D -- Abbott, James C -- Amselem, Joelle -- Burgis, Timothy A -- Soanes, Darren M -- Stuber, Kurt -- Ver Loren van Themaat, Emiel -- Brown, James K M -- Butcher, Sarah A -- Gurr, Sarah J -- Lebrun, Marc-Henri -- Ridout, Christopher J -- Schulze-Lefert, Paul -- Talbot, Nicholas J -- Ahmadinejad, Nahal -- Ametz, Christian -- Barton, Geraint R -- Benjdia, Mariam -- Bidzinski, Przemyslaw -- Bindschedler, Laurence V -- Both, Maike -- Brewer, Marin T -- Cadle-Davidson, Lance -- Cadle-Davidson, Molly M -- Collemare, Jerome -- Cramer, Rainer -- Frenkel, Omer -- Godfrey, Dale -- Harriman, James -- Hoede, Claire -- King, Brian C -- Klages, Sven -- Kleemann, Jochen -- Knoll, Daniela -- Koti, Prasanna S -- Kreplak, Jonathan -- Lopez-Ruiz, Francisco J -- Lu, Xunli -- Maekawa, Takaki -- Mahanil, Siraprapa -- Micali, Cristina -- Milgroom, Michael G -- Montana, Giovanni -- Noir, Sandra -- O'Connell, Richard J -- Oberhaensli, Simone -- Parlange, Francis -- Pedersen, Carsten -- Quesneville, Hadi -- Reinhardt, Richard -- Rott, Matthias -- Sacristan, Soledad -- Schmidt, Sarah M -- Schon, Moritz -- Skamnioti, Pari -- Sommer, Hans -- Stephens, Amber -- Takahara, Hiroyuki -- Thordal-Christensen, Hans -- Vigouroux, Marielle -- Wessling, Ralf -- Wicker, Thomas -- Panstruga, Ralph -- BB/E0009831/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E002803/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/H001948/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1543-6. doi: 10.1126/science.1194573.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Sciences, Imperial College London, London, UK. p.spanu@imperial.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148392" target="_blank"〉PubMed〈/a〉
