    Description: Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and the sudden oak death pathogen Phytophthora ramorum. Oomycetes such as these Phytophthora species share the kingdom Stramenopila with photosynthetic algae such as diatoms, and the presence of many Phytophthora genes of probable phototroph origin supports a photosynthetic ancestry for the stramenopiles. Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oomycete avirulence genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tyler, Brett M -- Tripathy, Sucheta -- Zhang, Xuemin -- Dehal, Paramvir -- Jiang, Rays H Y -- Aerts, Andrea -- Arredondo, Felipe D -- Baxter, Laura -- Bensasson, Douda -- Beynon, Jim L -- Chapman, Jarrod -- Damasceno, Cynthia M B -- Dorrance, Anne E -- Dou, Daolong -- Dickerman, Allan W -- Dubchak, Inna L -- Garbelotto, Matteo -- Gijzen, Mark -- Gordon, Stuart G -- Govers, Francine -- Grunwald, Niklaus J -- Huang, Wayne -- Ivors, Kelly L -- Jones, Richard W -- Kamoun, Sophien -- Krampis, Konstantinos -- Lamour, Kurt H -- Lee, Mi-Kyung -- McDonald, W Hayes -- Medina, Monica -- Meijer, Harold J G -- Nordberg, Eric K -- Maclean, Donald J -- Ospina-Giraldo, Manuel D -- Morris, Paul F -- Phuntumart, Vipaporn -- Putnam, Nicholas H -- Rash, Sam -- Rose, Jocelyn K C -- Sakihama, Yasuko -- Salamov, Asaf A -- Savidor, Alon -- Scheuring, Chantel F -- Smith, Brian M -- Sobral, Bruno W S -- Terry, Astrid -- Torto-Alalibo, Trudy A -- Win, Joe -- Xu, Zhanyou -- Zhang, Hongbin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Boore, Jeffrey L -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1261-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Virginia Bioinformatics Institute, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. bmtyler@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946064" target="_blank"〉PubMed〈/a〉

    Description: We investigated extraneural manifestations in scrapie-infected transgenic mice expressing prion protein lacking the glycophosphatydylinositol membrane anchor. In the brain, blood, and heart, both abnormal protease-resistant prion protein (PrPres) and prion infectivity were readily detected by immunoblot and by inoculation into nontransgenic recipients. The titer of infectious scrapie in blood plasma exceeded 10(7) 50% infectious doses per milliliter. The hearts of these transgenic mice contained PrPres-positive amyloid deposits that led to myocardial stiffness and cardiac disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1820586/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1820586/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trifilo, Matthew J -- Yajima, Toshitaka -- Gu, Yusu -- Dalton, Nancy -- Peterson, Kirk L -- Race, Richard E -- Meade-White, Kimberly -- Portis, John L -- Masliah, Eliezer -- Knowlton, Kirk U -- Chesebro, Bruce -- Oldstone, Michael B A -- 5R01HL66424-04/HL/NHLBI NIH HHS/ -- AGO4342/PHS HHS/ -- NS041219-05/NS/NINDS NIH HHS/ -- P01 AG004342/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):94-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Viral-Immunobiology Laboratory, Departments of Molecular and Integrative Neurosciences and Infectology, Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16825571" target="_blank"〉PubMed〈/a〉

    Description: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability. We report variations in planktonic foraminifera from varved sediments off southern California spanning the past 1400 years. Increasing abundances of tropical/subtropical species throughout the 20th century reflect a warming trend superimposed on decadal-scale fluctuations. Decreasing abundances of temperate/subpolar species in the late 20th century indicate a deep, penetrative warming not observed in previous centuries. These results imply that 20th-century warming, apparently anthropogenic, has already affected lower trophic levels of the California Current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Field, David B -- Baumgartner, Timothy R -- Charles, Christopher D -- Ferreira-Bartrina, Vicente -- Ohman, Mark D -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093, USA. dfield@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400144" target="_blank"〉PubMed〈/a〉

    Description: Litter decomposition provides the primary source of mineral nitrogen (N) for biological activity in most terrestrial ecosystems. A 10-year decomposition experiment in 21 sites from seven biomes found that net N release from leaf litter is dominantly driven by the initial tissue N concentration and mass remaining regardless of climate, edaphic conditions, or biota. Arid grasslands exposed to high ultraviolet radiation were an exception, where net N release was insensitive to initial N. Roots released N linearly with decomposition and exhibited little net N immobilization. We suggest that fundamental constraints on decomposer physiologies lead to predictable global-scale patterns in net N release during decomposition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parton, William -- Silver, Whendee L -- Burke, Ingrid C -- Grassens, Leo -- Harmon, Mark E -- Currie, William S -- King, Jennifer Y -- Adair, E Carol -- Brandt, Leslie A -- Hart, Stephen C -- Fasth, Becky -- New York, N.Y. -- Science. 2007 Jan 19;315(5810):361-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Natural Resource Ecology Laboratory, Colorado State University, 200 West Lake, Campus Mail 1499, Fort Collins, CO 80523-1499, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17234944" target="_blank"〉PubMed〈/a〉

    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

    Description: Information on responses of higher organisms to climate change is dominated by events in spring. Far less is known about autumnal events and virtually nothing about communities of microorganisms. We analyzed autumnal fruiting patterns of macrofungi over the past 56 years and found that average first fruiting date of 315 species is earlier, while last fruiting date is later. Fruiting of mycorrhizal species that associate with both deciduous and coniferous trees is delayed in deciduous, but not in coniferous, forests. Many species are now fruiting twice a year, indicating increased mycelial activity and possibly greater decay rates in ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gange, A C -- Gange, E G -- Sparks, T H -- Boddy, L -- New York, N.Y. -- Science. 2007 Apr 6;316(5821):71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, Royal Holloway, University of London, Egham, Surrey TW20 0EX, UK. a.gange@rhul.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17412949" target="_blank"〉PubMed〈/a〉

    Description: Sea anemones are seemingly primitive animals that, along with corals, jellyfish, and hydras, constitute the oldest eumetazoan phylum, the Cnidaria. Here, we report a comparative analysis of the draft genome of an emerging cnidarian model, the starlet sea anemone Nematostella vectensis. The sea anemone genome is complex, with a gene repertoire, exon-intron structure, and large-scale gene linkage more similar to vertebrates than to flies or nematodes, implying that the genome of the eumetazoan ancestor was similarly complex. Nearly one-fifth of the inferred genes of the ancestor are eumetazoan novelties, which are enriched for animal functions like cell signaling, adhesion, and synaptic transmission. Analysis of diverse pathways suggests that these gene "inventions" along the lineage leading to animals were likely already well integrated with preexisting eukaryotic genes in the eumetazoan progenitor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Srivastava, Mansi -- Hellsten, Uffe -- Dirks, Bill -- Chapman, Jarrod -- Salamov, Asaf -- Terry, Astrid -- Shapiro, Harris -- Lindquist, Erika -- Kapitonov, Vladimir V -- Jurka, Jerzy -- Genikhovich, Grigory -- Grigoriev, Igor V -- Lucas, Susan M -- Steele, Robert E -- Finnerty, John R -- Technau, Ulrich -- Martindale, Mark Q -- Rokhsar, Daniel S -- 5 P41 LM006252-09/LM/NLM NIH HHS/ -- THL007279F/PHS HHS/ -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):86-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615350" target="_blank"〉PubMed〈/a〉

    Description: Grid cells in layer II of rat entorhinal cortex fire to spatial locations in a repeating hexagonal grid, with smaller spacing between grid fields for neurons in more dorsal anatomical locations. Data from in vitro whole-cell patch recordings showed differences in frequency of subthreshold membrane potential oscillations in entorhinal neurons that correspond to different positions along the dorsal-to-ventral axis, supporting a model of physiological mechanisms for grid cell responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2950607/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2950607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giocomo, Lisa M -- Zilli, Eric A -- Fransen, Erik -- Hasselmo, Michael E -- DA16454/DA/NIDA NIH HHS/ -- MH60013/MH/NIMH NIH HHS/ -- MH71702/MH/NIMH NIH HHS/ -- P50 MH071702/MH/NIMH NIH HHS/ -- P50 MH071702-01A20004/MH/NIMH NIH HHS/ -- R01 DA016454/DA/NIDA NIH HHS/ -- R01 DA016454-04/DA/NIDA NIH HHS/ -- R01 DA016454-05/DA/NIDA NIH HHS/ -- R01 MH060013/MH/NIMH NIH HHS/ -- R01 MH060013-05/MH/NIMH NIH HHS/ -- R01 MH060013-06/MH/NIMH NIH HHS/ -- R01 MH061492/MH/NIMH NIH HHS/ -- R01 MH061492-05/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 23;315(5819):1719-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Memory and Brain, Department of Psychology, Program in Neuroscience, Boston University, 2 Cummington Street, Boston, MA 02215, USA. giocomo@bu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17379810" target="_blank"〉PubMed〈/a〉

    Description: Because bacterial recombination involves the occasional transfer of small DNA fragments between strains, different sets of niche-specific genes may be maintained in populations that freely recombine at other loci. Therefore, genetic isolation may be established at different times for different chromosomal regions during speciation as recombination at niche-specific genes is curtailed. To test this model, we separated sequence divergence into rate and time components, revealing that different regions of the Escherichia coli and Salmonella enterica chromosomes diverged over a approximately 70-million-year period. Genetic isolation first occurred at regions carrying species-specific genes, indicating that physiological distinctiveness between the nascent Escherichia and Salmonella lineages was maintained for tens of millions of years before the complete genetic isolation of their chromosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Retchless, Adam C -- Lawrence, Jeffrey G -- GM078092/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Aug 24;317(5841):1093-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Pittsburgh, Pittsburgh, PA 15260, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17717188" target="_blank"〉PubMed〈/a〉

    Description: Transection of the direct cortico-motoneuronal pathway at the mid-cervical segment of the spinal cord in the macaque monkey results in a transient impairment of finger movements. Finger dexterity recovers within a few months. Combined brain imaging and reversible pharmacological inactivation of motor cortical regions suggest that the recovery involves the bilateral primary motor cortex during the early recovery stage and more extensive regions of the contralesional primary motor cortex and bilateral premotor cortex during the late recovery stage. These changes in the activation pattern of frontal motor-related areas represent an adaptive strategy for functional compensation after spinal cord injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nishimura, Yukio -- Onoe, Hirotaka -- Morichika, Yosuke -- Perfiliev, Sergei -- Tsukada, Hideo -- Isa, Tadashi -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1150-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Physiology, National Institute for Physiological Sciences, Okazaki 444-8585, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006750" target="_blank"〉PubMed〈/a〉

    Description: Memory encoding occurs rapidly, but the consolidation of memory in the neocortex has long been held to be a more gradual process. We now report, however, that systems consolidation can occur extremely quickly if an associative "schema" into which new information is incorporated has previously been created. In experiments using a hippocampal-dependent paired-associate task for rats, the memory of flavor-place associations became persistent over time as a putative neocortical schema gradually developed. New traces, trained for only one trial, then became assimilated and rapidly hippocampal-independent. Schemas also played a causal role in the creation of lasting associative memory representations during one-trial learning. The concept of neocortical schemas may unite psychological accounts of knowledge structures with neurobiological theories of systems memory consolidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tse, Dorothy -- Langston, Rosamund F -- Kakeyama, Masaki -- Bethus, Ingrid -- Spooner, Patrick A -- Wood, Emma R -- Witter, Menno P -- Morris, Richard G M -- G9200370/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Apr 6;316(5821):76-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Cognitive Neuroscience, Centre for Cognitive and Neural Systems, and Centre for Neuroscience Research, University of Edinburgh, 1 George Square, Edinburgh EH8 9JZ, Scotland, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17412951" target="_blank"〉PubMed〈/a〉

    Description: Branching morphogenesis is one of the earliest events essential for the success of metazoans. By branching out and forming cellular or tissue extensions, cells can maximize their surface area and overcome space constraints posed by organ size. Over the past decade, tremendous progress has been made toward understanding the branching mechanisms of various invertebrate and vertebrate organ systems. Despite their distinct origins, morphologies and functions, different cell and tissue types use a remarkably conserved set of tools to undergo branching morphogenesis. Recent studies have shed important light on the basis of molecular conservation in the formation of branched structures in diverse organs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2645229/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2645229/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Pengfei -- Werb, Zena -- CA057621/CA/NCI NIH HHS/ -- ES012801/ES/NIEHS NIH HHS/ -- R01 CA057621/CA/NCI NIH HHS/ -- R01 CA057621-16A1/CA/NCI NIH HHS/ -- U01 ES012801-06/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 5;322(5907):1506-9. doi: 10.1126/science.1162783.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Program in Developmental Biology, University of California at San Francisco, San Francisco, CA 94143-0452, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19056977" target="_blank"〉PubMed〈/a〉

    Description: It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representing 3.5 million specimens, but only when older analytical protocols are used. Moreover, analyses that employ sampling standardization and more robust counting methods show a modest rise in diversity with no clear trend after the mid-Cretaceous. Globally, locally, and at both high and low latitudes, diversity was less than twice as high in the Neogene as in the mid-Paleozoic. The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alroy, John -- Aberhan, Martin -- Bottjer, David J -- Foote, Michael -- Fursich, Franz T -- Harries, Peter J -- Hendy, Austin J W -- Holland, Steven M -- Ivany, Linda C -- Kiessling, Wolfgang -- Kosnik, Matthew A -- Marshall, Charles R -- McGowan, Alistair J -- Miller, Arnold I -- Olszewski, Thomas D -- Patzkowsky, Mark E -- Peters, Shanan E -- Villier, Loic -- Wagner, Peter J -- Bonuso, Nicole -- Borkow, Philip S -- Brenneis, Benjamin -- Clapham, Matthew E -- Fall, Leigh M -- Ferguson, Chad A -- Hanson, Victoria L -- Krug, Andrew Z -- Layou, Karen M -- Leckey, Erin H -- Nurnberg, Sabine -- Powers, Catherine M -- Sessa, Jocelyn A -- Simpson, Carl -- Tomasovych, Adam -- Visaggi, Christy C -- New York, N.Y. -- Science. 2008 Jul 4;321(5885):97-100. doi: 10.1126/science.1156963.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, University of California-Santa Barbara, 735 State Street, Santa Barbara, CA 93101, USA. alroy@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18599780" target="_blank"〉PubMed〈/a〉

    Description: Increasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon fuels a high priority. Biofuels are a potential low-carbon energy source, but whether biofuels offer carbon savings depends on how they are produced. Converting rainforests, peatlands, savannas, or grasslands to produce food crop-based biofuels in Brazil, Southeast Asia, and the United States creates a "biofuel carbon debt" by releasing 17 to 420 times more CO2 than the annual greenhouse gas (GHG) reductions that these biofuels would provide by displacing fossil fuels. In contrast, biofuels made from waste biomass or from biomass grown on degraded and abandoned agricultural lands planted with perennials incur little or no carbon debt and can offer immediate and sustained GHG advantages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fargione, Joseph -- Hill, Jason -- Tilman, David -- Polasky, Stephen -- Hawthorne, Peter -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1235-8. doi: 10.1126/science.1152747.

    Description: The residence time of fine-root carbon in soil is one of the least understood aspects of the global carbon cycle, and fine-root dynamics are one of the least understood aspects of plant function. Most recent studies of these belowground dynamics have used one of two methodological strategies. In one approach, based on analysis of carbon isotopes, the persistence of carbon is inferred; in the other, based on direct observations of roots with cameras, the longevity of individual roots is measured. We show that the contribution of fine roots to the global carbon cycle has been overstated because observations of root lifetimes systematically overestimate the turnover of fine-root biomass. On the other hand, isotopic techniques systematically underestimate the turnover of individual roots. These differences, by virtue of the separate processes or pools measured, are irreconcilable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strand, Allan E -- Pritchard, Seth G -- McCormack, M Luke -- Davis, Micheal A -- Oren, Ram -- New York, N.Y. -- Science. 2008 Jan 25;319(5862):456-8. doi: 10.1126/science.1151382.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, College of Charleston, Charleston, SC 29424, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18218895" target="_blank"〉PubMed〈/a〉

    Description: Recent experiments with rats suggest that they show episodic-like or what-where-when memory for a preferred food found on a radial maze. Although memory for when a salient event occurred suggests that rats can mentally travel in time to a moment in the past, an alternative possibility is that they remember how long ago the food was found. Three groups of rats were tested for memory of previously encountered food. The different groups could use only the cues of when, how long ago, or when + how long ago. Only the cue of how long ago food was encountered was used successfully. These results suggest that episodic-like memory in rats is qualitatively different from human episodic memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, William A -- Feeney, Miranda C -- Macpherson, Krista -- Petter, Mark -- McMillan, Neil -- Musolino, Evanya -- New York, N.Y. -- Science. 2008 Apr 4;320(5872):113-5. doi: 10.1126/science.1152709.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Western Ontario, London, Ontario, N6A 5C2, Canada. roberts@uwo.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18388296" target="_blank"〉PubMed〈/a〉

    Description: We provide a century-scale view of small-mammal responses to global warming, without confounding effects of land-use change, by repeating Grinnell's early-20th century survey across a 3000-meter-elevation gradient that spans Yosemite National Park, California, USA. Using occupancy modeling to control for variation in detectability, we show substantial ( approximately 500 meters on average) upward changes in elevational limits for half of 28 species monitored, consistent with the observed approximately 3 degrees C increase in minimum temperatures. Formerly low-elevation species expanded their ranges and high-elevation species contracted theirs, leading to changed community composition at mid- and high elevations. Elevational replacement among congeners changed because species' responses were idiosyncratic. Though some high-elevation species are threatened, protection of elevation gradients allows other species to respond via migration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moritz, Craig -- Patton, James L -- Conroy, Chris J -- Parra, Juan L -- White, Gary C -- Beissinger, Steven R -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):261-4. doi: 10.1126/science.1163428.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum of Vertebrate Zoology, University of California, Berkeley, CA 94720, USA. craigm@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18845755" target="_blank"〉PubMed〈/a〉

    Description: Loss-of-function genetic screens in model organisms have elucidated numerous biological processes, but the diploid genome of mammalian cells has precluded large-scale gene disruption. We used insertional mutagenesis to develop a screening method to generate null alleles in a human cell line haploid for all chromosomes except chromosome 8. Using this approach, we identified host factors essential for infection with influenza and genes encoding important elements of the biosynthetic pathway of diphthamide, which are required for the cytotoxic effects of diphtheria toxin and exotoxin A. We also identified genes needed for the action of cytolethal distending toxin, including a cell-surface protein that interacts with the toxin. This approach has both conceptual and practical parallels with genetic approaches in haploid yeast.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carette, Jan E -- Guimaraes, Carla P -- Varadarajan, Malini -- Park, Annie S -- Wuethrich, Irene -- Godarova, Alzbeta -- Kotecki, Maciej -- Cochran, Brent H -- Spooner, Eric -- Ploegh, Hidde L -- Brummelkamp, Thijn R -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1231-5. doi: 10.1126/science.1178955.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965467" target="_blank"〉PubMed〈/a〉

    Description: We modeled the mobility of mobile phone users in order to study the fundamental spreading patterns that characterize a mobile virus outbreak. We find that although Bluetooth viruses can reach all susceptible handsets with time, they spread slowly because of human mobility, offering ample opportunities to deploy antiviral software. In contrast, viruses using multimedia messaging services could infect all users in hours, but currently a phase transition on the underlying call graph limits them to only a small fraction of the susceptible users. These results explain the lack of a major mobile virus breakout so far and predict that once a mobile operating system's market share reaches the phase transition point, viruses will pose a serious threat to mobile communications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Pu -- Gonzalez, Marta C -- Hidalgo, Cesar A -- Barabasi, Albert-Laszlo -- New York, N.Y. -- Science. 2009 May 22;324(5930):1071-6. doi: 10.1126/science.1167053.

    Description: The light detection and ranging instrument on the Phoenix mission observed water-ice clouds in the atmosphere of Mars that were similar to cirrus clouds on Earth. Fall streaks in the cloud structure traced the precipitation of ice crystals toward the ground. Measurements of atmospheric dust indicated that the planetary boundary layer (PBL) on Mars was well mixed, up to heights of around 4 kilometers, by the summer daytime turbulence and convection. The water-ice clouds were detected at the top of the PBL and near the ground each night in late summer after the air temperature started decreasing. The interpretation is that water vapor mixed upward by daytime turbulence and convection forms ice crystal clouds at night that precipitate back toward the surface.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whiteway, J A -- Komguem, L -- Dickinson, C -- Cook, C -- Illnicki, M -- Seabrook, J -- Popovici, V -- Duck, T J -- Davy, R -- Taylor, P A -- Pathak, J -- Fisher, D -- Carswell, A I -- Daly, M -- Hipkin, V -- Zent, A P -- Hecht, M H -- Wood, S E -- Tamppari, L K -- Renno, N -- Moores, J E -- Lemmon, M T -- Daerden, F -- Smith, P H -- New York, N.Y. -- Science. 2009 Jul 3;325(5936):68-70. doi: 10.1126/science.1172344.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Space Science and Engineering, York University, Toronto, Ontario, Canada. whiteway@yorku.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19574386" target="_blank"〉PubMed〈/a〉

    Description: Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change. These broadly distributed primary producers belong to an anciently diverged sister clade to land plants. Although Micromonas isolates have high 18S ribosomal RNA gene identity, we found that genomes from two isolates shared only 90% of their predicted genes. Their independent evolutionary paths were emphasized by distinct riboswitch arrangements as well as the discovery of intronic repeat elements in one isolate, and in metagenomic data, but not in other genomes. Divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolates differently than the core genes. Analyses of the Micromonas genomes offer valuable insights into ecological differentiation and the dynamic nature of early plant evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worden, Alexandra Z -- Lee, Jae-Hyeok -- Mock, Thomas -- Rouze, Pierre -- Simmons, Melinda P -- Aerts, Andrea L -- Allen, Andrew E -- Cuvelier, Marie L -- Derelle, Evelyne -- Everett, Meredith V -- Foulon, Elodie -- Grimwood, Jane -- Gundlach, Heidrun -- Henrissat, Bernard -- Napoli, Carolyn -- McDonald, Sarah M -- Parker, Micaela S -- Rombauts, Stephane -- Salamov, Aasf -- Von Dassow, Peter -- Badger, Jonathan H -- Coutinho, Pedro M -- Demir, Elif -- Dubchak, Inna -- Gentemann, Chelle -- Eikrem, Wenche -- Gready, Jill E -- John, Uwe -- Lanier, William -- Lindquist, Erika A -- Lucas, Susan -- Mayer, Klaus F X -- Moreau, Herve -- Not, Fabrice -- Otillar, Robert -- Panaud, Olivier -- Pangilinan, Jasmyn -- Paulsen, Ian -- Piegu, Benoit -- Poliakov, Aaron -- Robbens, Steven -- Schmutz, Jeremy -- Toulza, Eve -- Wyss, Tania -- Zelensky, Alexander -- Zhou, Kemin -- Armbrust, E Virginia -- Bhattacharya, Debashish -- Goodenough, Ursula W -- Van de Peer, Yves -- Grigoriev, Igor V -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):268-72. doi: 10.1126/science.1167222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95039 USA. azworden@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359590" target="_blank"〉PubMed〈/a〉

    Description: In the early stages of viral infection, outcomes depend on a race between expansion of infection and the immune response generated to contain it. We combined in situ tetramer staining with in situ hybridization to visualize, map, and quantify relationships between immune effector cells and their targets in tissues. In simian immunodeficiency virus infections in macaques and lymphocytic choriomeningitis virus infections in mice, the magnitude and timing of the establishment of an excess of effector cells versus targets were found to correlate with the extent of control and the infection outcome (i.e., control and clearance versus partial or poor control and persistent infection). This method highlights the importance of the location, timing, and magnitude of the immune response needed for a vaccine to be effective against agents of persistent infection, such as HIV-1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753492/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753492/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Qingsheng -- Skinner, Pamela J -- Ha, Sang-Jun -- Duan, Lijie -- Mattila, Teresa L -- Hage, Aaron -- White, Cara -- Barber, Daniel L -- O'Mara, Leigh -- Southern, Peter J -- Reilly, Cavan S -- Carlis, John V -- Miller, Christopher J -- Ahmed, Rafi -- Haase, Ashley T -- AI066314/AI/NIAID NIH HHS/ -- AI20048/AI/NIAID NIH HHS/ -- AI48484/AI/NIAID NIH HHS/ -- P01 AI066314/AI/NIAID NIH HHS/ -- P01 AI066314-010003/AI/NIAID NIH HHS/ -- P01 AI066314-020003/AI/NIAID NIH HHS/ -- P01 AI066314-030003/AI/NIAID NIH HHS/ -- P01 AI066314-040003/AI/NIAID NIH HHS/ -- P51 RR000169/RR/NCRR NIH HHS/ -- P51 RR000169-430198/RR/NCRR NIH HHS/ -- R01 AI048484/AI/NIAID NIH HHS/ -- R01 AI048484-01/AI/NIAID NIH HHS/ -- R01 AI048484-02/AI/NIAID NIH HHS/ -- R01 AI048484-03/AI/NIAID NIH HHS/ -- R01 AI048484-04/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1726-9. doi: 10.1126/science.1168676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Medical School, University of Minnesota, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325114" target="_blank"〉PubMed〈/a〉

    Description: The paradigmatic feature of long-term memory (LTM) is its persistence. However, little is known about the mechanisms that make some LTMs last longer than others. In rats, a long-lasting fear LTM vanished rapidly when the D1 dopamine receptor antagonist SCH23390 was injected into the dorsal hippocampus 12 hours, but not immediately or 9 hours, after the fearful experience. Conversely, intrahippocampal application of the D1 agonist SK38393 at the same critical post-training time converted a rapidly decaying fear LTM into a persistent one. This effect was mediated by brain-derived neurotrophic factor and regulated by the ventral tegmental area (VTA). Thus, the persistence of LTM depends on activation of VTA/hippocampus dopaminergic connections and can be specifically modulated by manipulating this system at definite post-learning time points.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rossato, Janine I -- Bevilaqua, Lia R M -- Izquierdo, Ivan -- Medina, Jorge H -- Cammarota, Martin -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):1017-20. doi: 10.1126/science.1172545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro de Memoria, Instituto do Cerebro, Pontificia Universidade Catolica do Rio Grande do Sul, Porto Alegre, Brazil.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19696353" target="_blank"〉PubMed〈/a〉

    Description: Similarities in the behavior of diverse animal species that form large groups have motivated attempts to establish general principles governing animal group behavior. It has been difficult, however, to make quantitative measurements of the temporal and spatial behavior of extensive animal groups in the wild, such as bird flocks, fish shoals, and locust swarms. By quantifying the formation processes of vast oceanic fish shoals during spawning, we show that (i) a rapid transition from disordered to highly synchronized behavior occurs as population density reaches a critical value; (ii) organized group migration occurs after this transition; and (iii) small sets of leaders significantly influence the actions of much larger groups. Each of these findings confirms general theoretical predictions believed to apply in nature irrespective of animal species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makris, Nicholas C -- Ratilal, Purnima -- Jagannathan, Srinivasan -- Gong, Zheng -- Andrews, Mark -- Bertsatos, Ioannis -- Godo, Olav Rune -- Nero, Redwood W -- Jech, J Michael -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1734-7. doi: 10.1126/science.1169441.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139, USA. makris@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325116" target="_blank"〉PubMed〈/a〉

Because of its relevance and availability, written correspondence provides a powerful proxy for studying human activity. One school of thought is that human correspondence is driven by responses to received correspondence, a view that requires a distinct response mechanism to explain e-mail and letter correspondence observations. We demonstrate that, like e-mail correspondence, the letter correspondence patterns of 16 writers, performers, politicians, and scientists are well described by the circadian cycle, task repetition, and changing communication needs. We confirm the universality of these mechanisms by rescaling letter and e-mail correspondence statistics to reveal their underlying similarity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malmgren, R Dean -- Stouffer, Daniel B -- Campanharo, Andriana S L O -- Amaral, Luis A Nunes -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1696-700. doi: 10.1126/science.1174562.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical and Biological Engineering, Northwestern University, Evanston, IL 60208, USA. dean.malmgren@u.northwestern.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779200" target="_blank"〉PubMed〈/a〉

    Description: Words, grammar, and phonology are linguistically distinct, yet their neural substrates are difficult to distinguish in macroscopic brain regions. We investigated whether they can be separated in time and space at the circuit level using intracranial electrophysiology (ICE), namely by recording local field potentials from populations of neurons using electrodes implanted in language-related brain regions while people read words verbatim or grammatically inflected them (present/past or singular/plural). Neighboring probes within Broca's area revealed distinct neuronal activity for lexical (approximately 200 milliseconds), grammatical (approximately 320 milliseconds), and phonological (approximately 450 milliseconds) processing, identically for nouns and verbs, in a region activated in the same patients and task in functional magnetic resonance imaging. This suggests that a linguistic processing sequence predicted on computational grounds is implemented in the brain in fine-grained spatiotemporally patterned activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030760/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Ned T -- Pinker, Steven -- Cash, Sydney S -- Schomer, Donald -- Halgren, Eric -- HD18381/HD/NICHD NIH HHS/ -- NS18741/NS/NINDS NIH HHS/ -- NS44623/NS/NINDS NIH HHS/ -- P41 RR014075/RR/NCRR NIH HHS/ -- P41 RR014075-02/RR/NCRR NIH HHS/ -- P41-RR14075/RR/NCRR NIH HHS/ -- R01 HD018381-18/HD/NICHD NIH HHS/ -- R01 NS018741/NS/NINDS NIH HHS/ -- R01 NS018741-22/NS/NINDS NIH HHS/ -- R01 NS044623/NS/NINDS NIH HHS/ -- R01 NS044623-03/NS/NINDS NIH HHS/ -- T32 MH070328-03/MH/NIMH NIH HHS/ -- T32-MH070328/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):445-9. doi: 10.1126/science.1174481.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiology, University of California-San Diego, La Jolla, CA 92037, USA. sahin@post.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833971" target="_blank"〉PubMed〈/a〉

    Description: Phytoplankton--the microalgae that populate the upper lit layers of the ocean--fuel the oceanic food web and affect oceanic and atmospheric carbon dioxide levels through photosynthetic carbon fixation. Here, we show that multidecadal changes in global phytoplankton abundances are related to basin-scale oscillations of the physical ocean, specifically the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation. This relationship is revealed in approximately 20 years of satellite observations of chlorophyll and sea surface temperature. Interaction between the main pycnocline and the upper ocean seasonal mixed layer is one mechanism behind this correlation. Our findings provide a context for the interpretation of contemporary changes in global phytoplankton and should improve predictions of their future evolution with climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez, Elodie -- Antoine, David -- D'Ortenzio, Fabrizio -- Gentili, Bernard -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1253-6. doi: 10.1126/science.1177012.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UPMC University of Paris 06, UMR 7093, Laboratoire d'Oceanographie de Villefranche (LOV), 06230 Villefranche-sur-Mer, France. martinez@obs-vlfr.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965473" target="_blank"〉PubMed〈/a〉

    Description: The genomic diversity and relative importance of distinct genotypes within natural bacterial populations have remained largely unknown. Here, we analyze the diversity and annual dynamics of a group of coastal bacterioplankton (greater than 99% 16S ribosomal RNA identity to Vibrio splendidus). We show that this group consists of at least a thousand distinct genotypes, each occurring at extremely low environmental concentrations (on average less than one cell per milliliter). Overall, the genomes show extensive allelic diversity and size variation. Individual genotypes rarely recurred in samples, and allelic distribution did not show spatial or temporal substructure. Ecological considerations suggest that much genotypic and possibly phenotypic variation within natural populations should be considered neutral.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thompson, Janelle R -- Pacocha, Sarah -- Pharino, Chanathip -- Klepac-Ceraj, Vanja -- Hunt, Dana E -- Benoit, Jennifer -- Sarma-Rupavtarm, Ramahi -- Distel, Daniel L -- Polz, Martin F -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1311-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Civil and Environmental Engineering, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15731455" target="_blank"〉PubMed〈/a〉

    Description: The activation dynamics of the transcription factor NF-kappaB exhibit damped oscillatory behavior when cells are stimulated by tumor necrosis factor-alpha (TNFalpha) but stable behavior when stimulated by lipopolysaccharide (LPS). LPS binding to Toll-like receptor 4 (TLR4) causes activation of NF-kappaB that requires two downstream pathways, each of which when isolated exhibits damped oscillatory behavior. Computational modeling of the two TLR4-dependent signaling pathways suggests that one pathway requires a time delay to establish early anti-phase activation of NF-kappaB by the two pathways. The MyD88-independent pathway required Inferon regulatory factor 3-dependent expression of TNFalpha to activate NF-kappaB, and the time required for TNFalpha synthesis established the delay.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Covert, Markus W -- Leung, Thomas H -- Gaston, Jahlionais E -- Baltimore, David -- GM039458-21/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1854-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16166516" target="_blank"〉PubMed〈/a〉

    Description: The oceans are becoming more acidic due to absorption of anthropogenic carbon dioxide from the atmosphere. The impact of ocean acidification on marine ecosystems is unclear, but it will likely depend on species adaptability and the rate of change of seawater pH relative to its natural variability. To constrain the natural variability in reef-water pH, we measured boron isotopic compositions in a approximately 300-year-old massive Porites coral from the southwestern Pacific. Large variations in pH are found over approximately 50-year cycles that covary with the Interdecadal Pacific Oscillation of ocean-atmosphere anomalies, suggesting that natural pH cycles can modulate the impact of ocean acidification on coral reef ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pelejero, Carles -- Calvo, Eva -- McCulloch, Malcolm T -- Marshall, John F -- Gagan, Michael K -- Lough, Janice M -- Opdyke, Bradley N -- New York, N.Y. -- Science. 2005 Sep 30;309(5744):2204-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research School of Earth Sciences, Australian National University, Canberra, ACT 0200, Australia. pelejero@cmima.csic.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16195458" target="_blank"〉PubMed〈/a〉

    Description: After anaphase onset, animal cells build an actomyosin contractile ring that constricts the plasma membrane to generate two daughter cells connected by a cytoplasmic bridge. The bridge is ultimately severed to complete cytokinesis. Myriad techniques have been used to identify proteins that participate in cytokinesis in vertebrates, insects, and nematodes. A conserved core of about 20 proteins are individually involved with cytokinesis in most animal cells. These components are found in the contractile ring, on the central spindle, within the RhoA pathway, and on vesicles that expand the membrane and sever the bridge. Cytokinesis involves additional proteins, but they, or their requirement in cytokinesis, are not conserved among animal cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glotzer, Michael -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1735-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology, Dr. BohrGasse 7, A-1030 Vienna, Austria. mglotzer@imp.univie.ac.at〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774750" target="_blank"〉PubMed〈/a〉

    Description: Lighter variations of pigmentation in humans are associated with diminished number, size, and density of melanosomes, the pigmented organelles of melanocytes. Here we show that zebrafish golden mutants share these melanosomal changes and that golden encodes a putative cation exchanger slc24a5 (nckx5) that localizes to an intracellular membrane, likely the melanosome or its precursor. The human ortholog is highly similar in sequence and functional in zebrafish. The evolutionarily conserved ancestral allele of a human coding polymorphism predominates in African and East Asian populations. In contrast, the variant allele is nearly fixed in European populations, is associated with a substantial reduction in regional heterozygosity, and correlates with lighter skin pigmentation in admixed populations, suggesting a key role for the SLC24A5 gene in human pigmentation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamason, Rebecca L -- Mohideen, Manzoor-Ali P K -- Mest, Jason R -- Wong, Andrew C -- Norton, Heather L -- Aros, Michele C -- Jurynec, Michael J -- Mao, Xianyun -- Humphreville, Vanessa R -- Humbert, Jasper E -- Sinha, Soniya -- Moore, Jessica L -- Jagadeeswaran, Pudur -- Zhao, Wei -- Ning, Gang -- Makalowska, Izabela -- McKeigue, Paul M -- O'donnell, David -- Kittles, Rick -- Parra, Esteban J -- Mangini, Nancy J -- Grunwald, David J -- Shriver, Mark D -- Canfield, Victor A -- Cheng, Keith C -- CA73935/CA/NCI NIH HHS/ -- EY11308/EY/NEI NIH HHS/ -- HD37572/HD/NICHD NIH HHS/ -- HD40179/HD/NICHD NIH HHS/ -- HG002154/HG/NHGRI NIH HHS/ -- HL077910/HL/NHLBI NIH HHS/ -- RR017441/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2005 Dec 16;310(5755):1782-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jake Gittlen Cancer Research Foundation, Department of Pathology, The Pennsylvania State University College of Medicine, Hershey, PA 17033, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16357253" target="_blank"〉PubMed〈/a〉

    Description: The typical scales for plant and fungal movements vary over many orders of magnitude in time and length, but they are ultimately based on hydraulics and mechanics. We show that quantification of the length and time scales involved in plant and fungal motions leads to a natural classification, whose physical basis can be understood through an analysis of the mechanics of water transport through an elastic tissue. Our study also suggests a design principle for nonmuscular hydraulically actuated structures: Rapid actuation requires either small size or the enhancement of motion on large scales via elastic instabilities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skotheim, Jan M -- Mahadevan, L -- New York, N.Y. -- Science. 2005 May 27;308(5726):1308-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Mathematics and Theoretical Physics, Centre for Mathematical Sciences, University of Cambridge, Cambridge CB3 0WA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15919993" target="_blank"〉PubMed〈/a〉

    Description: Flowering of Arabidopsis is regulated by several environmental and endogenous signals. An important integrator of these inputs is the FLOWERING LOCUS T (FT) gene, which encodes a small, possibly mobile protein. A primary response to floral induction is the activation of FT RNA expression in leaves. Because flowers form at a distant site, the shoot apex, these data suggest that FT primarily controls the timing of flowering. Integration of temporal and spatial information is mediated in part by the bZIP transcription factor FD, which is already expressed at the shoot apex before floral induction. A complex of FT and FD proteins in turn can activate floral identity genes such as APETALA1 (AP1).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wigge, Philip A -- Kim, Min Chul -- Jaeger, Katja E -- Busch, Wolfgang -- Schmid, Markus -- Lohmann, Jan U -- Weigel, Detlef -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1056-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Max Planck Institute for Developmental Biology, 72076 Tubingen, Germany. philip.wigge@bbsrc.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099980" target="_blank"〉PubMed〈/a〉

    Description: Rapid global warming of 5 degrees to 10 degrees C during the Paleocene-Eocene Thermal Maximum (PETM) coincided with major turnover in vertebrate faunas, but previous studies have found little floral change. Plant fossils discovered in Wyoming, United States, show that PETM floras were a mixture of native and migrant lineages and that plant range shifts were large and rapid (occurring within 10,000 years). Floral composition and leaf shape and size suggest that climate warmed by approximately 5 degrees C during the PETM and that precipitation was low early in the event and increased later.

    Description: The open oceans comprise most of the biosphere, yet patterns and trends of species diversity there are enigmatic. Here, we derive worldwide patterns of tuna and billfish diversity over the past 50 years, revealing distinct subtropical "hotspots" that appeared to hold generally for other predators and zooplankton. Diversity was positively correlated with thermal fronts and dissolved oxygen and a nonlinear function of temperature (approximately 25 degrees C optimum). Diversity declined between 10 and 50% in all oceans, a trend that coincided with increased fishing pressure, superimposed on strong El Nino-Southern Oscillation-driven variability across the Pacific. We conclude that predator diversity shows a predictable yet eroding pattern signaling ecosystem-wide changes linked to climate and fishing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worm, Boris -- Sandow, Marcel -- Oschlies, Andreas -- Lotze, Heike K -- Myers, Ransom A -- New York, N.Y. -- Science. 2005 Aug 26;309(5739):1365-9.

    Description: Determining what fraction of texts and manuscripts have survived from Antiquity and the Middle Ages has been highly problematic. Analyzing the transmission of texts as the "paleodemography" of their manuscripts yields definite and surprisingly high estimates. Parchment copies of the foremost medieval textbooks on arithmetical and calendrical calculation closely fit age distributions expected for populations with logistic growth and manuscripts with exponential survivorship. The estimated half-lives of copies agree with Bischoff's paleographically based suggestion that roughly one in seven manuscripts survive in some form from ninth-century Carolingian workshops. On this basis, many if not most of the leading technical titles circulating in Latin probably survived, even from late Antiquity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cisne, John L -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1305-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Atmospheric Sciences, Cornell University, Ithaca, NY 14853, USA. cisne@geology.cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15731453" target="_blank"〉PubMed〈/a〉

    Description: The capacity to generate and analyze mental visual images is essential for many cognitive abilities. We combined triple-pulse transcranial magnetic stimulation (tpTMS) and repetitive TMS (rTMS) to determine which distinct aspect of mental imagery is carried out by the left and right parietal lobe and to reveal interhemispheric compensatory interactions. The left parietal lobe was predominant in generating mental images, whereas the right parietal lobe was specialized in the spatial comparison of the imagined content. Furthermore, in case of an rTMS-induced left parietal lesion, the right parietal cortex could immediately compensate such a left parietal disruption by taking over the specific function of the left hemisphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sack, A T -- Camprodon, J A -- Pascual-Leone, A -- Goebel, R -- K24 RR018875/RR/NCRR NIH HHS/ -- NCRR MO1 RR01032/RR/NCRR NIH HHS/ -- R01MH60734/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2005 Apr 29;308(5722):702-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cognitive Neuroscience, Faculty of Psychology, Maastricht University, Post Office Box 616, 6200 MD Maastricht, Netherlands. a.sack@psychology.unimaas.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15860630" target="_blank"〉PubMed〈/a〉

    Description: The species complexity of microbial communities and challenges in culturing representative isolates make it difficult to obtain assembled genomes. Here we characterize and compare the metabolic capabilities of terrestrial and marine microbial communities using largely unassembled sequence data obtained by shotgun sequencing DNA isolated from the various environments. Quantitative gene content analysis reveals habitat-specific fingerprints that reflect known characteristics of the sampled environments. The identification of environment-specific genes through a gene-centric comparative analysis presents new opportunities for interpreting and diagnosing environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tringe, Susannah Green -- von Mering, Christian -- Kobayashi, Arthur -- Salamov, Asaf A -- Chen, Kevin -- Chang, Hwai W -- Podar, Mircea -- Short, Jay M -- Mathur, Eric J -- Detter, John C -- Bork, Peer -- Hugenholtz, Philip -- Rubin, Edward M -- New York, N.Y. -- Science. 2005 Apr 22;308(5721):554-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy (DOE) Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15845853" target="_blank"〉PubMed〈/a〉

    Description: The primary event that initiates vision is the light-induced 11-cis to all-trans isomerization of retinal in the visual pigment rhodopsin. Despite decades of study with the traditional tools of chemical reaction dynamics, both the timing and nature of the atomic motions that lead to photoproduct production remain unknown. We used femtosecond-stimulated Raman spectroscopy to obtain time-resolved vibrational spectra of the molecular structures formed along the reaction coordinate. The spectral evolution of the vibrational features from 200 femtoseconds to 1 picosecond after photon absorption reveals the temporal sequencing of the geometric changes in the retinal backbone that activate this receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kukura, Philipp -- McCamant, David W -- Yoon, Sangwoon -- Wandschneider, Daniel B -- Mathies, Richard A -- EY-02051/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2005 Nov 11;310(5750):1006-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16284176" target="_blank"〉PubMed〈/a〉

    Description: The contribution of language history to the study of the early dispersals of modern humans throughout the Old World has been limited by the shallow time depth (about 8000 +/- 2000 years) of current linguistic methods. Here it is shown that the application of biological cladistic methods, not to vocabulary (as has been previously tried) but to language structure (sound systems and grammar), may extend the time depths at which language data can be used. The method was tested against well-understood families of Oceanic Austronesian languages, then applied to the Papuan languages of Island Melanesia, a group of hitherto unrelatable isolates. Papuan languages show an archipelago-based phylogenetic signal that is consistent with the current geographical distribution of languages. The most plausible hypothesis to explain this result is the divergence of the Papuan languages from a common ancestral stock, as part of late Pleistocene dispersals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dunn, Michael -- Terrill, Angela -- Reesink, Ger -- Foley, Robert A -- Levinson, Stephen C -- New York, N.Y. -- Science. 2005 Sep 23;309(5743):2072-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Psycholinguistics, Post Office Box 310, 6500 AH Nijmegen, Netherlands. michael.dunn@mpi.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16179483" target="_blank"〉PubMed〈/a〉

    Description: We identified axonal defects in mouse models of Alzheimer's disease that preceded known disease-related pathology by more than a year; we observed similar axonal defects in the early stages of Alzheimer's disease in humans. Axonal defects consisted of swellings that accumulated abnormal amounts of microtubule-associated and molecular motor proteins, organelles, and vesicles. Impairing axonal transport by reducing the dosage of a kinesin molecular motor protein enhanced the frequency of axonal defects and increased amyloid-beta peptide levels and amyloid deposition. Reductions in microtubule-dependent transport may stimulate proteolytic processing of beta-amyloid precursor protein, resulting in the development of senile plaques and Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stokin, Gorazd B -- Lillo, Concepcion -- Falzone, Tomas L -- Brusch, Richard G -- Rockenstein, Edward -- Mount, Stephanie L -- Raman, Rema -- Davies, Peter -- Masliah, Eliezer -- Williams, David S -- Goldstein, Lawrence S B -- EY12598/EY/NEI NIH HHS/ -- EY13408/EY/NEI NIH HHS/ -- P50 AG05131/AG/NIA NIH HHS/ -- R01 EY007042/EY/NEI NIH HHS/ -- R01 EY007042-19/EY/NEI NIH HHS/ -- R01 EY013408/EY/NEI NIH HHS/ -- R01 EY013408-02/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1282-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Cellular and Molecular Medicine, School of Medicine, University of California San Diego (UCSD), 9500 Gilman Drive, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15731448" target="_blank"〉PubMed〈/a〉

    Description: Highly pathogenic avian influenza A (subtype H5N1) is threatening to cause a human pandemic of potentially devastating proportions. We used a stochastic influenza simulation model for rural Southeast Asia to investigate the effectiveness of targeted antiviral prophylaxis, quarantine, and pre-vaccination in containing an emerging influenza strain at the source. If the basic reproductive number (R0) was below 1.60, our simulations showed that a prepared response with targeted antivirals would have a high probability of containing the disease. In that case, an antiviral agent stockpile on the order of 100,000 to 1 million courses for treatment and prophylaxis would be sufficient. If pre-vaccination occurred, then targeted antiviral prophylaxis could be effective for containing strains with an R0 as high as 2.1. Combinations of targeted antiviral prophylaxis, pre-vaccination, and quarantine could contain strains with an R(0) as high as 2.4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Longini, Ira M Jr -- Nizam, Azhar -- Xu, Shufu -- Ungchusak, Kumnuan -- Hanshaoworakul, Wanna -- Cummings, Derek A T -- Halloran, M Elizabeth -- R01-AI32042/AI/NIAID NIH HHS/ -- U01-GM070749/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1083-7.

In contrast, the same genes robustly resolved phylogenetic relationships within a major clade of Fungi of approximately the same age as the Metazoa. The differences in resolution within the two kingdoms suggest that the early history of metazoans was a radiation compressed in time, a finding that is in agreement with paleontological inferences. Furthermore, simulation analyses as well as studies of other radiations in deep time indicate that, given adequate sequence data, the lack of resolution in phylogenetic trees is a signature of closely spaced series of cladogenetic events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rokas, Antonis -- Kruger, Dirk -- Carroll, Sean B -- New York, N.Y. -- Science. 2005 Dec 23;310(5756):1933-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Laboratory of Molecular Biology, R.

    Description: A major suspected bias in the fossil record of skeletonized groups is variation in preservability owing to differences in shell composition. However, despite extensive changes in shell composition over the 500-million-year history of marine bivalves, genus duration and shell composition show few significant relationships, and of those, virtually all are contrary to bias from preferential loss of highly reactive shell types. Distortion of large-scale temporal patterns in marine bivalves owing to preservability is thus apparently weak or randomly distributed, which increases the likelihood that observed patterns in this and other shelled groups carry a strong biological signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kidwell, Susan M -- New York, N.Y. -- Science. 2005 Feb 11;307(5711):914-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637, USA. skidwell@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15705849" target="_blank"〉PubMed〈/a〉

    Description: Understanding the brain computations leading to object recognition requires quantitative characterization of the information represented in inferior temporal (IT) cortex. We used a biologically plausible, classifier-based readout technique to investigate the neural coding of selectivity and invariance at the IT population level. The activity of small neuronal populations (approximately 100 randomly selected cells) over very short time intervals (as small as 12.5 milliseconds) contained unexpectedly accurate and robust information about both object "identity" and "category." This information generalized over a range of object positions and scales, even for novel objects. Coarse information about position and scale could also be read out from the same population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hung, Chou P -- Kreiman, Gabriel -- Poggio, Tomaso -- DiCarlo, James J -- New York, N.Y. -- Science. 2005 Nov 4;310(5749):863-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McGovern Institute for Brain Research, Cambridge, MA 02139, USA. chouhung@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16272124" target="_blank"〉PubMed〈/a〉

    Description: Bats make up more than 20% of extant mammals, yet their evolutionary history is largely unknown because of a limited fossil record and conflicting or incomplete phylogenies. Here, we present a highly resolved molecular phylogeny for all extant bat families. Our results support the hypothesis that megabats are nested among four major microbat lineages, which originated in the early Eocene [52 to 50 million years ago (Mya)], coincident with a significant global rise in temperature, increase in plant diversity and abundance, and the zenith of Tertiary insect diversity. Our data suggest that bats originated in Laurasia, possibly in North America, and that three of the major microbat lineages are Laurasian in origin, whereas the fourth is Gondwanan. Combining principles of ghost lineage analysis with molecular divergence dates, we estimate that the bat fossil record underestimates (unrepresented basal branch length, UBBL) first occurrences by, on average, 73% and that the sum of missing fossil history is 61%.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teeling, Emma C -- Springer, Mark S -- Madsen, Ole -- Bates, Paul -- O'brien, Stephen J -- Murphy, William J -- N01-CO-12400/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):580-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genomic Diversity, Basic Research Program, SAIC-Frederick, Inc., National Cancer Institute, Frederick, MD 21702, USA. emma.teeling@ucd.ie〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15681385" target="_blank"〉PubMed〈/a〉

    Description: Removal of top predators from ecosystems can result in cascading effects through the trophic levels below, completely restructuring the food web. Cascades have been observed in small-scale or simple food webs, but not in large, complex, open-ocean ecosystems. Using data spanning many decades from a once cod-dominated northwest Atlantic ecosystem, we demonstrate a trophic cascade in a large marine ecosystem. Several cod stocks in other geographic areas have also collapsed without recovery, suggesting the existence of trophic cascades in these systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frank, Kenneth T -- Petrie, Brian -- Choi, Jae S -- Leggett, William C -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1621-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Oceans, Bedford Institute of Oceanography, Ocean Sciences Division, Post Office Box 1006, Dartmouth, Nova Scotia, B2Y 4A2, Canada. frankk@mar.dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15947186" target="_blank"〉PubMed〈/a〉

    Description: Quantifying long-range dissemination of infectious diseases is a key issue in their dynamics and control. Here, we use influenza-related mortality data to analyze the between-state progression of interpandemic influenza in the United States over the past 30 years. Outbreaks show hierarchical spatial spread evidenced by higher pairwise synchrony between more populous states. Seasons with higher influenza mortality are associated with higher disease transmission and more rapid spread than are mild ones. The regional spread of infection correlates more closely with rates of movement of people to and from their workplaces (workflows) than with geographical distance. Workflows are described in turn by a gravity model, with a rapid decay of commuting up to around 100 km and a long tail of rare longer range flow. A simple epidemiological model, based on the gravity formulation, captures the observed increase of influenza spatial synchrony with transmissibility; high transmission allows influenza to spread rapidly beyond local spatial constraints.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Viboud, Cecile -- Bjornstad, Ottar N -- Smith, David L -- Simonsen, Lone -- Miller, Mark A -- Grenfell, Bryan T -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):447-51.

    Description: Dispersal is often risky to the individual, yet the long-term survival of populations depends on having a sufficient number of individuals that move, find each other, and locate suitable breeding habitats. This tension has consequences that rarely meet our conservation or management goals. This is particularly true in changing environments, which makes the study of dispersal urgently topical in a world plagued with habitat loss, climate change, and species introductions. Despite the difficulty of tracking mobile individuals over potentially vast ranges, recent research has revealed a multitude of ways in which dispersal evolution can either constrain, or accelerate, species' responses to environmental changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kokko, Hanna -- Lopez-Sepulcre, Andres -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):789-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Ecological and Evolutionary Dynamics, Department of Biological and Environmental Science, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FIN-00014 Helsinki, Finland. hanna.kokko@helsinki.fi〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902127" target="_blank"〉PubMed〈/a〉

    Description: Environmental temperature is thought to be directly sensed by neurons through their projections in the skin. A subset of the mammalian transient receptor potential (TRP) family of ion channels has been implicated in this process. These "thermoTRPs" are activated at distinct temperature thresholds and are typically expressed in sensory neurons. TRPV3 is activated by heat (〉33 degrees C) and, unlike most thermoTRPs, is expressed in mouse keratinocytes. We found that TRPV3 null mice have strong deficits in responses to innocuous and noxious heat but not in other sensory modalities; hence, TRPV3 has a specific role in thermosensation. The natural compound camphor, which modulates sensations of warmth in humans, proved to be a specific activator of TRPV3. Camphor activated cultured primary keratinocytes but not sensory neurons, and this activity was abolished in TRPV3 null mice. Therefore, heat-activated receptors in keratinocytes are important for mammalian thermosensation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moqrich, Aziz -- Hwang, Sun Wook -- Earley, Taryn J -- Petrus, Matt J -- Murray, Amber N -- Spencer, Kathryn S R -- Andahazy, Mary -- Story, Gina M -- Patapoutian, Ardem -- New York, N.Y. -- Science. 2005 Mar 4;307(5714):1468-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15746429" target="_blank"〉PubMed〈/a〉

    Description: MicroRNAs (miRNAs) are small noncoding RNAs, about 21 nucleotides in length, that can regulate gene expression by base-pairing to partially complementary mRNAs. Regulation by miRNAs can play essential roles in embryonic development. We determined the temporal and spatial expression patterns of 115 conserved vertebrate miRNAs in zebrafish embryos by microarrays and by in situ hybridizations, using locked-nucleic acid-modified oligonucleotide probes. Most miRNAs were expressed in a highly tissue-specific manner during segmentation and later stages, but not early in development, which suggests that their role is not in tissue fate establishment but in differentiation or maintenance of tissue identity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wienholds, Erno -- Kloosterman, Wigard P -- Miska, Eric -- Alvarez-Saavedra, Ezequiel -- Berezikov, Eugene -- de Bruijn, Ewart -- Horvitz, H Robert -- Kauppinen, Sakari -- Plasterk, Ronald H A -- New York, N.Y. -- Science. 2005 Jul 8;309(5732):310-1.

We used this device to observe the dynamics of Escherichia coli carrying a synthetic "population control" circuit that regulates cell density through a feedback mechanism based on quorum sensing. The microfluidic bioreactor enabled long-term monitoring of unnatural behavior programmed by the synthetic circuit, which included sustained oscillations in cell density and associated morphological changes, over hundreds of hours.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Balagadde, Frederick K -- You, Lingchong -- Hansen, Carl L -- Arnold, Frances H -- Quake, Stephen R -- New York, N.Y. -- Science. 2005 Jul 1;309(5731):137-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Physics, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15994559" target="_blank"〉PubMed〈/a〉

    Description: We report direct structural evidence of the bridged radical (CH2ICH2.) in a polar solution, obtained using time-resolved liquid-phase x-ray diffraction. This transient intermediate has long been hypothesized to explain stereo-chemical control in many association and/or dissociation reactions involving haloalkanes. Ultrashort optical pulses were used to dissociate an iodine atom from the haloethane molecule (C2H4I2) dissolved in methanol, and the diffraction of picosecond x-ray pulses from a synchrotron supports the following structural dynamics, with approximately 0.01 angstrom spatial resolution and approximately 100 picosecond time resolution: The loss of one iodine atom from C2H4I2 leads to the C-I-C triangular geometry of CH2ICH2.. This transient C2H4I then binds to an iodine atom to form a new species, the C2H4I-I isomer, which eventually decays into C2H4 + I2. Solvent dynamics were also extracted from the data, revealing a change in the solvent cage geometry, heating, and thermal expansion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ihee, H -- Lorenc, M -- Kim, T K -- Kong, Q Y -- Cammarata, M -- Lee, J H -- Bratos, S -- Wulff, M -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1223-7.
