Description: The field of optogenetics uses channelrhodopsins (ChRs) for light-induced neuronal activation. However, optimized tools for cellular inhibition at moderate light levels are lacking. We found that replacement of E90 in the central gate of ChR with positively charged residues produces chloride-conducting ChRs (ChloCs) with only negligible cation conductance. Molecular dynamics modeling unveiled that a high-affinity Cl(-)-binding site had been generated near the gate. Stabilizing the open state dramatically increased the operational light sensitivity of expressing cells (slow ChloC). In CA1 pyramidal cells, ChloCs completely inhibited action potentials triggered by depolarizing current injections or synaptic stimulation. Thus, by inverting the charge of the selectivity filter, we have created a class of directly light-gated anion channels that can be used to block neuronal output in a fully reversible fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wietek, Jonas -- Wiegert, J Simon -- Adeishvili, Nona -- Schneider, Franziska -- Watanabe, Hiroshi -- Tsunoda, Satoshi P -- Vogt, Arend -- Elstner, Marcus -- Oertner, Thomas G -- Hegemann, Peter -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):409-12. doi: 10.1126/science.1249375.

Description: Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion of repetitive elements, large segmental deletions, and gene loss. Avian genomes furthermore show a remarkably high degree of evolutionary stasis at the levels of nucleotide sequence, gene synteny, and chromosomal structure. Despite this pattern of conservation, we detected many non-neutral evolutionary changes in protein-coding genes and noncoding regions. These analyses reveal that pan-avian genomic diversity covaries with adaptations to different lifestyles and convergent evolution of traits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4390078/" 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/PMC4390078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guojie -- Li, Cai -- Li, Qiye -- Li, Bo -- Larkin, Denis M -- Lee, Chul -- Storz, Jay F -- Antunes, Agostinho -- Greenwold, Matthew J -- Meredith, Robert W -- Odeen, Anders -- Cui, Jie -- Zhou, Qi -- Xu, Luohao -- Pan, Hailin -- Wang, Zongji -- Jin, Lijun -- Zhang, Pei -- Hu, Haofu -- Yang, Wei -- Hu, Jiang -- Xiao, Jin -- Yang, Zhikai -- Liu, Yang -- Xie, Qiaolin -- Yu, Hao -- Lian, Jinmin -- Wen, Ping -- Zhang, Fang -- Li, Hui -- Zeng, Yongli -- Xiong, Zijun -- Liu, Shiping -- Zhou, Long -- Huang, Zhiyong -- An, Na -- Wang, Jie -- Zheng, Qiumei -- Xiong, Yingqi -- Wang, Guangbiao -- Wang, Bo -- Wang, Jingjing -- Fan, Yu -- da Fonseca, Rute R -- Alfaro-Nunez, Alonzo -- Schubert, Mikkel -- Orlando, Ludovic -- Mourier, Tobias -- Howard, Jason T -- Ganapathy, Ganeshkumar -- Pfenning, Andreas -- Whitney, Osceola -- Rivas, Miriam V -- Hara, Erina -- Smith, Julia -- Farre, Marta -- Narayan, Jitendra -- Slavov, Gancho -- Romanov, Michael N -- Borges, Rui -- Machado, Joao Paulo -- Khan, Imran -- Springer, Mark S -- Gatesy, John -- Hoffmann, Federico G -- Opazo, Juan C -- Hastad, Olle -- Sawyer, Roger H -- Kim, Heebal -- Kim, Kyu-Won -- Kim, Hyeon Jeong -- Cho, Seoae -- Li, Ning -- Huang, Yinhua -- Bruford, Michael W -- Zhan, Xiangjiang -- Dixon, Andrew -- Bertelsen, Mads F -- Derryberry, Elizabeth -- Warren, Wesley -- Wilson, Richard K -- Li, Shengbin -- Ray, David A -- Green, Richard E -- O'Brien, Stephen J -- Griffin, Darren -- Johnson, Warren E -- Haussler, David -- Ryder, Oliver A -- Willerslev, Eske -- Graves, Gary R -- Alstrom, Per -- Fjeldsa, Jon -- Mindell, David P -- Edwards, Scott V -- Braun, Edward L -- Rahbek, Carsten -- Burt, David W -- Houde, Peter -- Zhang, Yong -- Yang, Huanming -- Wang, Jian -- Avian Genome Consortium -- Jarvis, Erich D -- Gilbert, M Thomas P -- Wang, Jun -- DP1 OD000448/OD/NIH HHS/ -- DP1OD000448/OD/NIH HHS/ -- R01 HL087216/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1311-20. doi: 10.1126/science.1251385.

Description: Lingham-Soliar questions our interpretation of integumentary structures in the Middle-Late Jurassic ornithischian dinosaur Kulindadromeus as feather-like appendages and alternatively proposes that the compound structures observed around the humerus and femur of Kulindadromeus are support fibers associated with badly degraded scales. We consider this hypothesis highly unlikely because of the taphonomy and morphology of the preserved structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Godefroit, Pascal -- Sinitsa, Sofia M -- Dhouailly, Danielle -- Bolotsky, Yuri L -- Sizov, Alexander V -- McNamara, Maria E -- Benton, Michael J -- Spagna, Paul -- New York, N.Y. -- Science. 2014 Oct 24;346(6208):434. doi: 10.1126/science.1260146.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Directorate, Earth and History of Life, Royal Belgian Institute of Natural Sciences, Rue Vautier 29, B-1000 Brussels, Belgium. pascal.godefroit@naturalsciences.be. ; Institute of Natural Resources, Ecology, and Cryology, 26 Butin Street, 672 014 Chita, Russia. ; UJF-CNRS FRE 3405, AGIM, Universite Joseph Fourier, Site Sante, 38 706 La Tronche, France. ; Institute of Geology and Nature Management, FEB RAS, 1 Relochny Street 675 000, Blagoveschensk, Russia. ; Institute of the Earth Crust, SB RAS, 128 Lermontov Street, 664 033 Irkutsk, Russia. ; School of Biological, Earth, and Environmental Science, University College Cork, Cork, Ireland.

Description: The excitatory neurotransmitter glutamate induces modulatory actions via the metabotropic glutamate receptors (mGlus), which are class C G protein-coupled receptors (GPCRs). We determined the structure of the human mGlu1 receptor seven-transmembrane (7TM) domain bound to a negative allosteric modulator, FITM, at a resolution of 2.8 angstroms. The modulator binding site partially overlaps with the orthosteric binding sites of class A GPCRs but is more restricted than most other GPCRs. We observed a parallel 7TM dimer mediated by cholesterols, which suggests that signaling initiated by glutamate's interaction with the extracellular domain might be mediated via 7TM interactions within the full-length receptor dimer. A combination of crystallography, structure-activity relationships, mutagenesis, and full-length dimer modeling provides insights about the allosteric modulation and activation mechanism of class C GPCRs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991565/" 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/PMC3991565/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Huixian -- Wang, Chong -- Gregory, Karen J -- Han, Gye Won -- Cho, Hyekyung P -- Xia, Yan -- Niswender, Colleen M -- Katritch, Vsevolod -- Meiler, Jens -- Cherezov, Vadim -- Conn, P Jeffrey -- Stevens, Raymond C -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DK097376/DK/NIDDK NIH HHS/ -- R01 GM080403/GM/NIGMS NIH HHS/ -- R01 GM099842/GM/NIGMS NIH HHS/ -- R01 MH062646/MH/NIMH NIH HHS/ -- R01 MH090192/MH/NIMH NIH HHS/ -- R01 NS031373/NS/NINDS NIH HHS/ -- R21 NS078262/NS/NINDS NIH HHS/ -- R37 NS031373/NS/NINDS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):58-64. doi: 10.1126/science.1249489.

Description: Reef-building in metazoans represents an important ecological innovation whereby individuals collectively enhance feeding efficiency and gain protection from competitors and predation. The appearance of metazoan reefs in the fossil record therefore indicates an adaptive response to complex ecological pressures. In the Nama Group, Namibia, we found evidence of reef-building by the earliest known skeletal metazoan, the globally distributed Cloudina, ~548 million years ago. These Cloudina reefs formed open frameworks without a microbial component but with mutual attachment and cementation between individuals. Orientated growth implies a passive suspension-feeding habit into nutrient-rich currents. The characteristics of Cloudina support the view that metazoan reef-building was promoted by the rise of substrate competitors and predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Penny, A M -- Wood, R -- Curtis, A -- Bowyer, F -- Tostevin, R -- Hoffman, K-H -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1504-6. doi: 10.1126/science.1253393.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of GeoSciences, University of Edinburgh, West Mains Road, Edinburgh EH9 3JW, UK. a.m.penny@ed.ac.uk. ; School of GeoSciences, University of Edinburgh, West Mains Road, Edinburgh EH9 3JW, UK. ; Department of Earth Sciences, University College London, Gower Street, London WC1E 6BT, UK. ; Geological Survey of Namibia, Private Bag 13297, Windhoek, Namibia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24970084" target="_blank"〉PubMed〈/a〉

Description: Reported trends in the mean and variability of coastal upwelling in eastern boundary currents have raised concerns about the future of these highly productive and biodiverse marine ecosystems. However, the instrumental records on which these estimates are based are insufficiently long to determine whether such trends exceed preindustrial limits. In the California Current, a 576-year reconstruction of climate variables associated with winter upwelling indicates that variability increased over the latter 20th century to levels equaled only twice during the past 600 years. This modern trend in variance may be unique, because it appears to be driven by an unprecedented succession of extreme, downwelling-favorable, winter climate conditions that profoundly reduce productivity for marine predators of commercial and conservation interest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Black, Bryan A -- Sydeman, William J -- Frank, David C -- Griffin, Daniel -- Stahle, David W -- Garcia-Reyes, Marisol -- Rykaczewski, Ryan R -- Bograd, Steven J -- Peterson, William T -- New York, N.Y. -- Science. 2014 Sep 19;345(6203):1498-502. doi: 10.1126/science.1253209.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Texas Marine Science Institute, 750 Channel View Drive, Port Aransas, TX 78373, USA. bryan.black@utexas.edu. ; Farallon Institute for Advanced Ecosystem Research, 101 H Street, Suite Q, Petaluma, CA 94952, USA. ; Swiss Federal Research Institute WSL, Zurcherstrasse 111, CH-8903 Birmensdorf, Switzerland and Oeschger Centre for Climate Change Research, University of Bern, Zahringerstrasse 25, CH-3012 Bern, Switzerland. ; Department of Geology and Geophysics, Woods Hole Oceanographic Institution, 266 Woods Hole Road, Woods Hole, MA 02543, USA. ; Department of Geosciences, University of Arkansas, 216 Ozark Hall, Fayetteville, AR 72701, USA. ; Department of Biological Sciences and Marine Science Program, University of South Carolina, 701 Sumter Street, Columbia, SC 29208, USA. ; Environmental Research Division, Southwest Fisheries Science Center, National Oceanic and Atmospheric Administration (NOAA), 1352 Lighthouse Avenue, Pacific Grove, CA 93950, USA. ; Northwest Fisheries Science Center, Hatfield Marine Science Center, NOAA, 2030 Southeast Marine Science Drive, Newport, OR 97365, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25237100" target="_blank"〉PubMed〈/a〉

Description: Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian phylogenetic range, and find that more than half of them do not have as fully degenerated W chromosomes as that of chicken. We show that avian sex chromosomes harbor tremendous diversity among species in their composition of pseudoautosomal regions and degree of Z/W differentiation. Punctuated events of shared or lineage-specific recombination suppression have produced a gradient of "evolutionary strata" along the Z chromosome, which initiates from the putative avian sex-determining gene DMRT1 and ends at the pseudoautosomal region. W-linked genes are subject to ongoing functional decay after recombination was suppressed, and the tempo of degeneration slows down in older strata. Overall, we unveil a complex history of avian sex chromosome evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Qi -- Zhang, Jilin -- Bachtrog, Doris -- An, Na -- Huang, Quanfei -- Jarvis, Erich D -- Gilbert, M Thomas P -- Zhang, Guojie -- GM076007/GM/NIGMS NIH HHS/ -- GM093182/GM/NIGMS NIH HHS/ -- R01 GM076007/GM/NIGMS NIH HHS/ -- R01 GM093182/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1246338. doi: 10.1126/science.1246338.

Description: In 1990, Andrew Bakun proposed that increasing greenhouse gas concentrations would force intensification of upwelling-favorable winds in eastern boundary current systems that contribute substantial services to society. Because there is considerable disagreement about whether contemporary wind trends support Bakun's hypothesis, we performed a meta-analysis of the literature on upwelling-favorable wind intensification. The preponderance of published analyses suggests that winds have intensified in the California, Benguela, and Humboldt upwelling systems and weakened in the Iberian system over time scales ranging up to 60 years; wind change is equivocal in the Canary system. Stronger intensification signals are observed at higher latitudes, consistent with the warming pattern associated with climate change. Overall, reported changes in coastal winds, although subtle and spatially variable, support Bakun's hypothesis of upwelling intensification in eastern boundary current systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sydeman, W J -- Garcia-Reyes, M -- Schoeman, D S -- Rykaczewski, R R -- Thompson, S A -- Black, B A -- Bograd, S J -- New York, N.Y. -- Science. 2014 Jul 4;345(6192):77-80. doi: 10.1126/science.1251635.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA. wsydeman@comcast.net. ; Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA. ; Faculty of Science, Health, Education and Engineering, University of the Sunshine Coast, Locked Bag 4, Maroochydore DC, Queensland 4558, Australia. ; Department of Biological Sciences and Marine Science Program, University of South Carolina, 701 Sumter Street, Columbia, SC 29208, USA. ; Farallon Institute for Advanced Ecosystem Research, Suite Q, 101 H Street, Petaluma, CA 94952, USA.

Description: Godefroit et al. (Reports, 25 July 2014, p. 451) reported scales and feathers, including "basal plates," in an ornithischian dinosaur. Their arguments against the filaments being collagen fibers are not supported because of a fundamental misinterpretation of such structures and underestimation of their size. The parsimonious explanation is that the filaments are support fibers in association with badly degraded scales and that they do not represent early feather stages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lingham-Soliar, Theagarten -- New York, N.Y. -- Science. 2014 Oct 24;346(6208):434. doi: 10.1126/science.1259983.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nelson Mandela Metropolitan University, Port Elizabeth, South Africa.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25342795" target="_blank"〉PubMed〈/a〉

Description: The prevention of fertilization through self-pollination (or pollination by a close relative) in the Brassicaceae plant family is determined by the genotype of the plant at the self-incompatibility locus (S locus). The many alleles at this locus exhibit a dominance hierarchy that determines which of the two allelic specificities of a heterozygous genotype is expressed at the phenotypic level. Here, we uncover the evolution of how at least 17 small RNA (sRNA)-producing loci and their multiple target sites collectively control the dominance hierarchy among alleles within the gene controlling the pollen S-locus phenotype in a self-incompatible Arabidopsis species. Selection has created a dynamic repertoire of sRNA-target interactions by jointly acting on sRNA genes and their target sites, which has resulted in a complex system of regulation among alleles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Durand, Eleonore -- Meheust, Raphael -- Soucaze, Marion -- Goubet, Pauline M -- Gallina, Sophie -- Poux, Celine -- Fobis-Loisy, Isabelle -- Guillon, Eline -- Gaude, Thierry -- Sarazin, Alexis -- Figeac, Martin -- Prat, Elisa -- Marande, William -- Berges, Helene -- Vekemans, Xavier -- Billiard, Sylvain -- Castric, Vincent -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1200-5. doi: 10.1126/science.1259442.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire Genetique et Evolution des Populations Vegetales, CNRS UMR 8198, Universite Lille 1, F-59655 Villeneuve d'Ascq cedex, France. ; Reproduction et Developpement des Plantes, Institut Federatif de Recherche 128, Centre National de la Recherche Scientifique, Institut National de la Recherche Agronomique, Universite Claude Bernard Lyon I, Ecole Normale Superieure de Lyon, F-69364 Lyon, Cedex 07, France. ; Department of Biology, Swiss Federal Institute of Technology Zurich, CH-8093 Zurich, Switzerland. ; UDSL Universite Lille 2 Droit et Sante, and Plate-forme de genomique fonctionnelle et structurale IFR-114, F-59000 Lille, France. ; Centre National des Ressources Genomiques Vegetales, INRA UPR 1258, Castanet-Tolosan, France. ; Laboratoire Genetique et Evolution des Populations Vegetales, CNRS UMR 8198, Universite Lille 1, F-59655 Villeneuve d'Ascq cedex, France. vincent.castric@univ-lille1.fr.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25477454" target="_blank"〉PubMed〈/a〉

Description: In theoretical ecology, traditional studies based on dynamical stability and numerical simulations have not found a unified answer to the effect of network architecture on community persistence. Here, we introduce a mathematical framework based on the concept of structural stability to explain such a disparity of results. We investigated the range of conditions necessary for the stable coexistence of all species in mutualistic systems. We show that the apparently contradictory conclusions reached by previous studies arise as a consequence of overseeing either the necessary conditions for persistence or its dependence on model parameterization. We show that observed network architectures maximize the range of conditions for species coexistence. We discuss the applicability of structural stability to study other types of interspecific interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rohr, Rudolf P -- Saavedra, Serguei -- Bascompte, Jordi -- New York, N.Y. -- Science. 2014 Jul 25;345(6195):1253497. doi: 10.1126/science.1253497.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrative Ecology Group, Estacion Biologica de Donana-Consejo Superior de Investigaciones Cientificas (EBD-CSIC), Calle Americo Vespucio s/n, E-41092 Sevilla, Spain.

Description: Although substantial progress has been achieved in the structural analysis of exporters from the superfamily of adenosine triphosphate (ATP)-binding cassette (ABC) transporters, much less is known about how they selectively recognize substrates and how substrate binding is coupled to ATP hydrolysis. We have addressed these questions through crystallographic analysis of the Atm1/ABCB7/HMT1/ABCB6 ortholog from Novosphingobium aromaticivorans DSM 12444, NaAtm1, at 2.4 angstrom resolution. Consistent with a physiological role in cellular detoxification processes, functional studies showed that glutathione derivatives can serve as substrates for NaAtm1 and that its overexpression in Escherichia coli confers protection against silver and mercury toxicity. The glutathione binding site highlights the articulated design of ABC exporters, with ligands and nucleotides spanning structurally conserved elements to create adaptable interfaces accommodating conformational rearrangements during the transport cycle.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4151877/" 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/PMC4151877/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Jonas Y -- Yang, Janet G -- Zhitnitsky, Daniel -- Lewinson, Oded -- Rees, Douglas C -- GM45162/GM/NIGMS NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- R01 GM045162/GM/NIGMS NIH HHS/ -- R37 GM045162/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1133-6. doi: 10.1126/science.1246489.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Division of Chemistry and Chemical Engineering, Mail Code 114-96, 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/24604198" target="_blank"〉PubMed〈/a〉

Description: A major evolutionary transition to eusociality with reproductive division of labor between queens and workers has arisen independently at least 10 times in the ants, bees, and wasps. Pheromones produced by queens are thought to play a key role in regulating this complex social system, but their evolutionary history remains unknown. Here, we identify the first sterility-inducing queen pheromones in a wasp, bumblebee, and desert ant and synthesize existing data on compounds that characterize female fecundity in 64 species of social insects. Our results show that queen pheromones are strikingly conserved across at least three independent origins of eusociality, with wasps, ants, and some bees all appearing to use nonvolatile, saturated hydrocarbons to advertise fecundity and/or suppress worker reproduction. These results suggest that queen pheromones evolved from conserved signals of solitary ancestors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Oystaeyen, Annette -- Oliveira, Ricardo Caliari -- Holman, Luke -- van Zweden, Jelle S -- Romero, Carmen -- Oi, Cintia A -- d'Ettorre, Patrizia -- Khalesi, Mohammadreza -- Billen, Johan -- Wackers, Felix -- Millar, Jocelyn G -- Wenseleers, Tom -- New York, N.Y. -- Science. 2014 Jan 17;343(6168):287-90. doi: 10.1126/science.1244899.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Socioecology and Social Evolution, Zoological Institute, University of Leuven, Naamsestraat 59-Box 2466, 3000 Leuven, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24436417" target="_blank"〉PubMed〈/a〉

Description: Human mitochondrial ribosomes are highly divergent from all other known ribosomes and are specialized to exclusively translate membrane proteins. They are linked with hereditary mitochondrial diseases and are often the unintended targets of various clinically useful antibiotics. Using single-particle cryogenic electron microscopy, we have determined the structure of its large subunit to 3.4 angstrom resolution, revealing 48 proteins, 21 of which are specific to mitochondria. The structure unveils an adaptation of the exit tunnel for hydrophobic nascent peptides, extensive remodeling of the central protuberance, including recruitment of mitochondrial valine transfer RNA (tRNA(Val)) to play an integral structural role, and changes in the tRNA binding sites related to the unusual characteristics of mitochondrial tRNAs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4246062/" 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/PMC4246062/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, Alan -- Amunts, Alexey -- Bai, Xiao-chen -- Sugimoto, Yoichiro -- Edwards, Patricia C -- Murshudov, Garib -- Scheres, Sjors H W -- Ramakrishnan, V -- 096570/Wellcome Trust/United Kingdom -- MC_U105184332/Medical Research Council/United Kingdom -- MC_UP_A025_1012/Medical Research Council/United Kingdom -- MC_UP_A025_1013/Medical Research Council/United Kingdom -- WT096570/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Nov 7;346(6210):718-22. doi: 10.1126/science.1258026.

Description: Phosphatidylinositol 4-kinases (PI4Ks) and small guanosine triphosphatases (GTPases) are essential for processes that require expansion and remodeling of phosphatidylinositol 4-phosphate (PI4P)-containing membranes, including cytokinesis, intracellular development of malarial pathogens, and replication of a wide range of RNA viruses. However, the structural basis for coordination of PI4K, GTPases, and their effectors is unknown. Here, we describe structures of PI4Kbeta (PI4KIIIbeta) bound to the small GTPase Rab11a without and with the Rab11 effector protein FIP3. The Rab11-PI4KIIIbeta interface is distinct compared with known structures of Rab complexes and does not involve switch regions used by GTPase effectors. Our data provide a mechanism for how PI4KIIIbeta coordinates Rab11 and its effectors on PI4P-enriched membranes and also provide strategies for the design of specific inhibitors that could potentially target plasmodial PI4KIIIbeta to combat malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4046302/" 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/PMC4046302/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burke, John E -- Inglis, Alison J -- Perisic, Olga -- Masson, Glenn R -- McLaughlin, Stephen H -- Rutaganira, Florentine -- Shokat, Kevan M -- Williams, Roger L -- MC_U105184308/Medical Research Council/United Kingdom -- PG/11/109/29247/British Heart Foundation/United Kingdom -- PG11/109/29247/British Heart Foundation/United Kingdom -- R01AI099245/AI/NIAID NIH HHS/ -- T32 GM064337/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):1035-8. doi: 10.1126/science.1253397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. jeburke@uvic.ca rlw@mrc-lmb.cam.ac.uk. ; Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. ; Howard Hughes Medical Institute and Department of Cellular and Molecular Pharmacology, University of California, San Francisco (UCSF), San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24876499" target="_blank"〉PubMed〈/a〉

Description: Recent discoveries have highlighted the dramatic evolutionary transformation of massive, ground-dwelling theropod dinosaurs into light, volant birds. Here, we apply Bayesian approaches (originally developed for inferring geographic spread and rates of molecular evolution in viruses) in a different context: to infer size changes and rates of anatomical innovation (across up to 1549 skeletal characters) in fossils. These approaches identify two drivers underlying the dinosaur-bird transition. The theropod lineage directly ancestral to birds undergoes sustained miniaturization across 50 million years and at least 12 consecutive branches (internodes) and evolves skeletal adaptations four times faster than other dinosaurs. The distinct, prolonged phase of miniaturization along the bird stem would have facilitated the evolution of many novelties associated with small body size, such as reorientation of body mass, increased aerial ability, and paedomorphic skulls with reduced snouts but enlarged eyes and brains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Michael S Y -- Cau, Andrea -- Naish, Darren -- Dyke, Gareth J -- New York, N.Y. -- Science. 2014 Aug 1;345(6196):562-6. doi: 10.1126/science.1252243.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Earth Sciences Section, South Australian Museum, North Terrace, Adelaide 5000, Australia.

Description: Parenting behaviors, such as the provisioning of food by parents to offspring, are known to be highly responsive to changes in environment. However, we currently know little about how such flexibility affects the ways in which parenting is adapted and evolves in response to environmental variation. This is because few studies quantify how individuals vary in their response to changing environments, especially social environments created by other individuals with which parents interact. Social environmental factors differ from nonsocial factors, such as food availability, because parents and offspring both contribute and respond to the social environment they experience. This interdependence leads to the coevolution of flexible behaviors involved in parenting, which could, paradoxically, constrain the ability of individuals to rapidly adapt to changes in their nonsocial environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Royle, Nick J -- Russell, Andrew F -- Wilson, Alastair J -- BB/G022976/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):776-81. doi: 10.1126/science.1253294.

Description: Molecular chaperones prevent aggregation and misfolding of proteins, but scarcity of structural data has impeded an understanding of the recognition and antiaggregation mechanisms. We report the solution structure, dynamics, and energetics of three trigger factor (TF) chaperone molecules in complex with alkaline phosphatase (PhoA) captured in the unfolded state. Our data show that TF uses multiple sites to bind to several regions of the PhoA substrate protein primarily through hydrophobic contacts. Nuclear magnetic resonance (NMR) relaxation experiments show that TF interacts with PhoA in a highly dynamic fashion, but as the number and length of the PhoA regions engaged by TF increase, a more stable complex gradually emerges. Multivalent binding keeps the substrate protein in an extended, unfolded conformation. The results show how molecular chaperones recognize unfolded polypeptides and, by acting as unfoldases and holdases, prevent the aggregation and premature (mis)folding of unfolded proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4070327/" 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/PMC4070327/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saio, Tomohide -- Guan, Xiao -- Rossi, Paolo -- Economou, Anastassios -- Kalodimos, Charalampos G -- GM073854/GM/NIGMS NIH HHS/ -- R01 GM073854/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):1250494. doi: 10.1126/science.1250494.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrative Proteomics Research and Department of Chemistry and Chemical Biology, Rutgers University, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24812405" target="_blank"〉PubMed〈/a〉

Description: Ecologists have long sought to understand the factors controlling the structure of savanna vegetation. Using data from 2154 sites in savannas across Africa, Australia, and South America, we found that increasing moisture availability drives increases in fire and tree basal area, whereas fire reduces tree basal area. However, among continents, the magnitude of these effects varied substantially, so that a single model cannot adequately represent savanna woody biomass across these regions. Historical and environmental differences drive the regional variation in the functional relationships between woody vegetation, fire, and climate. These same differences will determine the regional responses of vegetation to future climates, with implications for global carbon stocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lehmann, Caroline E R -- Anderson, T Michael -- Sankaran, Mahesh -- Higgins, Steven I -- Archibald, Sally -- Hoffmann, William A -- Hanan, Niall P -- Williams, Richard J -- Fensham, Roderick J -- Felfili, Jeanine -- Hutley, Lindsay B -- Ratnam, Jayashree -- San Jose, Jose -- Montes, Ruben -- Franklin, Don -- Russell-Smith, Jeremy -- Ryan, Casey M -- Durigan, Giselda -- Hiernaux, Pierre -- Haidar, Ricardo -- Bowman, David M J S -- Bond, William J -- New York, N.Y. -- Science. 2014 Jan 31;343(6170):548-52. doi: 10.1126/science.1247355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Macquarie University, New South Wales 2109, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24482480" target="_blank"〉PubMed〈/a〉

Description: Primordial germ cell (PGC) specification occurs either by induction from pluripotent cells (epigenesis) or by a cell-autonomous mechanism mediated by germ plasm (preformation). Among vertebrates, epigenesis is basal, whereas germ plasm has evolved convergently across lineages and is associated with greater speciation. We compared protein-coding sequences of vertebrate species that employ preformation with their sister taxa that use epigenesis and demonstrate that genes evolve more rapidly in species containing germ plasm. Furthermore, differences in rates of evolution appear to cause phylogenetic incongruence in protein-coding sequence comparisons between vertebrate taxa. Our results support the hypothesis that germ plasm liberates constraints on somatic development and that enhanced evolvability drives the evolution of germ plasm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Evans, Teri -- Wade, Christopher M -- Chapman, Frank A -- Johnson, Andrew D -- Loose, Matthew -- G1100025/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Apr 11;344(6180):200-3. doi: 10.1126/science.1249325.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, University of Nottingham, Nottingham, NG7 2UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24723612" target="_blank"〉PubMed〈/a〉

Description: Integration of evidence over the past decade has revised understandings about the major adaptations underlying the origin and early evolution of the genus Homo. Many features associated with Homo sapiens, including our large linear bodies, elongated hind limbs, large energy-expensive brains, reduced sexual dimorphism, increased carnivory, and unique life history traits, were once thought to have evolved near the origin of the genus in response to heightened aridity and open habitats in Africa. However, recent analyses of fossil, archaeological, and environmental data indicate that such traits did not arise as a single package. Instead, some arose substantially earlier and some later than previously thought. From ~2.5 to 1.5 million years ago, three lineages of early Homo evolved in a context of habitat instability and fragmentation on seasonal, intergenerational, and evolutionary time scales. These contexts gave a selective advantage to traits, such as dietary flexibility and larger body size, that facilitated survival in shifting environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anton, Susan C -- Potts, Richard -- Aiello, Leslie C -- New York, N.Y. -- Science. 2014 Jul 4;345(6192):1236828. doi: 10.1126/science.1236828.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for the Study of Human Origins, Department of Anthropology, New York University, Rufus D.

Description: The oxygenation of Earth's surface fundamentally altered global biogeochemical cycles and ultimately paved the way for the rise of metazoans at the end of the Proterozoic. However, current estimates for atmospheric oxygen (O2) levels during the billion years leading up to this time vary widely. On the basis of chromium (Cr) isotope data from a suite of Proterozoic sediments from China, Australia, and North America, interpreted in the context of data from similar depositional environments from Phanerozoic time, we find evidence for inhibited oxidation of Cr at Earth's surface in the mid-Proterozoic (1.8 to 0.8 billion years ago). These data suggest that atmospheric O2 levels were at most 0.1% of present atmospheric levels. Direct evidence for such low O2 concentrations in the Proterozoic helps explain the late emergence and diversification of metazoans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Planavsky, Noah J -- Reinhard, Christopher T -- Wang, Xiangli -- Thomson, Danielle -- McGoldrick, Peter -- Rainbird, Robert H -- Johnson, Thomas -- Fischer, Woodward W -- Lyons, Timothy W -- New York, N.Y. -- Science. 2014 Oct 31;346(6209):635-8. doi: 10.1126/science.1258410.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department Geology and Geophysics, Yale University, CT, USA. noah.planavsky@yale.edu chris.reinhard@eas.gatech.edu. ; School of Earth and Atmospheric Sciences, Georgia Institute of Technology, GA, USA. noah.planavsky@yale.edu chris.reinhard@eas.gatech.edu. ; Department Geology and Geophysics, Yale University, CT, USA.

Description: Animal migrations span the globe, involving immense numbers of individuals from a wide range of taxa. Migrants transport nutrients, energy, and other organisms as they forage and are preyed upon throughout their journeys. These highly predictable, pulsed movements across large spatial scales render migration a potentially powerful yet underappreciated dimension of biodiversity that is intimately embedded within resident communities. We review examples from across the animal kingdom to distill fundamental processes by which migratory animals influence communities and ecosystems, demonstrating that they can uniquely alter energy flow, food-web topology and stability, trophic cascades, and the structure of metacommunities. Given the potential for migration to alter ecological networks worldwide, we suggest an integrative framework through which community dynamics and ecosystem functioning may explicitly consider animal migrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bauer, S -- Hoye, B J -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):1242552. doi: 10.1126/science.1242552.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bird Migration, Swiss Ornithological Institute, 6204 Sempach, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700862" target="_blank"〉PubMed〈/a〉

Description: In certain human cancers, the expression of critical oncogenes is driven from large regulatory elements, called super-enhancers, that recruit much of the cell's transcriptional apparatus and are defined by extensive acetylation of histone H3 lysine 27 (H3K27ac). In a subset of T-cell acute lymphoblastic leukemia (T-ALL) cases, we found that heterozygous somatic mutations are acquired that introduce binding motifs for the MYB transcription factor in a precise noncoding site, which creates a super-enhancer upstream of the TAL1 oncogene. MYB binds to this new site and recruits its H3K27 acetylase-binding partner CBP, as well as core components of a major leukemogenic transcriptional complex that contains RUNX1, GATA-3, and TAL1 itself. Additionally, most endogenous super-enhancers found in T-ALL cells are occupied by MYB and CBP, which suggests a general role for MYB in super-enhancer initiation. Thus, this study identifies a genetic mechanism responsible for the generation of oncogenic super-enhancers in malignant cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4720521/" 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/PMC4720521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mansour, Marc R -- Abraham, Brian J -- Anders, Lars -- Berezovskaya, Alla -- Gutierrez, Alejandro -- Durbin, Adam D -- Etchin, Julia -- Lawton, Lee -- Sallan, Stephen E -- Silverman, Lewis B -- Loh, Mignon L -- Hunger, Stephen P -- Sanda, Takaomi -- Young, Richard A -- Look, A Thomas -- 1R01CA176746-01/CA/NCI NIH HHS/ -- 5P01CA109901-08/CA/NCI NIH HHS/ -- 5P01CA68484/CA/NCI NIH HHS/ -- CA114766/CA/NCI NIH HHS/ -- CA120215/CA/NCI NIH HHS/ -- CA167124/CA/NCI NIH HHS/ -- CA29139/CA/NCI NIH HHS/ -- CA30969/CA/NCI NIH HHS/ -- CA98413/CA/NCI NIH HHS/ -- CA98543/CA/NCI NIH HHS/ -- P01 CA109901/CA/NCI NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- R01 HG002668/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1373-7. doi: 10.1126/science.1259037.

Description: N-Methyl-D-aspartate (NMDA) receptors belong to the family of ionotropic glutamate receptors, which mediate most excitatory synaptic transmission in mammalian brains. Calcium permeation triggered by activation of NMDA receptors is the pivotal event for initiation of neuronal plasticity. Here, we show the crystal structure of the intact heterotetrameric GluN1-GluN2B NMDA receptor ion channel at 4 angstroms. The NMDA receptors are arranged as a dimer of GluN1-GluN2B heterodimers with the twofold symmetry axis running through the entire molecule composed of an amino terminal domain (ATD), a ligand-binding domain (LBD), and a transmembrane domain (TMD). The ATD and LBD are much more highly packed in the NMDA receptors than non-NMDA receptors, which may explain why ATD regulates ion channel activity in NMDA receptors but not in non-NMDA receptors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4113085/" 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/PMC4113085/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karakas, Erkan -- Furukawa, Hiro -- MH085926/MH/NIMH NIH HHS/ -- R01 GM105730/GM/NIGMS NIH HHS/ -- R01 MH085926/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):992-7. doi: 10.1126/science.1251915.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, W.

Description: Potassium channels selectively conduct K(+) ions across cellular membranes with extraordinary efficiency. Their selectivity filter exhibits four binding sites with approximately equal electron density in crystal structures with high K(+) concentrations, previously thought to reflect a superposition of alternating ion- and water-occupied states. Consequently, cotranslocation of ions with water has become a widely accepted ion conduction mechanism for potassium channels. By analyzing more than 1300 permeation events from molecular dynamics simulations at physiological voltages, we observed instead that permeation occurs via ion-ion contacts between neighboring K(+) ions. Coulomb repulsion between adjacent ions is found to be the key to high-efficiency K(+) conduction. Crystallographic data are consistent with directly neighboring K(+) ions in the selectivity filter, and our model offers an intuitive explanation for the high throughput rates of K(+) channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kopfer, David A -- Song, Chen -- Gruene, Tim -- Sheldrick, George M -- Zachariae, Ulrich -- de Groot, Bert L -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):352-5. doi: 10.1126/science.1254840.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biomolecular Dynamics Group, Max Planck Institute for Biophysical Chemistry, 37077 Gottingen, Germany. ; Department of Biochemistry, University of Oxford, Oxford OX1 3QU, UK. sc3210@gmail.com u.zachariae@dundee.ac.uk bgroot@gwdg.de. ; Department of Structural Chemistry, University of Gottingen, 37077 Gottingen, Germany. ; School of Engineering, Physics and Mathematics, University of Dundee, Dundee DD1 4HN, UK.

Description: Middle Jurassic to Early Cretaceous deposits from northeastern China have yielded varied theropod dinosaurs bearing feathers. Filamentous integumentary structures have also been described in ornithischian dinosaurs, but whether these filaments can be regarded as part of the evolutionary lineage toward feathers remains controversial. Here we describe a new basal neornithischian dinosaur from the Jurassic of Siberia with small scales around the distal hindlimb, larger imbricated scales around the tail, monofilaments around the head and the thorax, and more complex featherlike structures around the humerus, the femur, and the tibia. The discovery of these branched integumentary structures outside theropods suggests that featherlike structures coexisted with scales and were potentially widespread among the entire dinosaur clade; feathers may thus have been present in the earliest dinosaurs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Godefroit, Pascal -- Sinitsa, Sofia M -- Dhouailly, Danielle -- Bolotsky, Yuri L -- Sizov, Alexander V -- McNamara, Maria E -- Benton, Michael J -- Spagna, Paul -- New York, N.Y. -- Science. 2014 Jul 25;345(6195):451-5. doi: 10.1126/science.1253351.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Directorate 'Earth and History of Life,' Royal Belgian Institute of Natural Sciences, Rue Vautier 29, B-1000 Brussels, Belgium. pascal.godefroit@naturalsciences.be. ; Institute of Natural Resources, Ecology and Cryology, 26 Butin Street, 672 014 Chita, Russia. ; UJF-CNRS FRE 3405, AGIM, Universite Joseph Fourier, Site Sante, 38 706 La Tronche, France. ; Institute of Geology and Nature Management, FEB RAS, 1 Relochny Street 675 000, Blagoveschensk, Russia. ; Institute of the Earth Crust, SB RAS, 128 Lermontov Street, Irkutsk, 664 033 Irkutsk, Russia. ; School of Biological, Earth and Environmental Science, University College Cork, Cork, Ireland.

Description: Edentulism, the absence of teeth, has evolved convergently among vertebrates, including birds, turtles, and several lineages of mammals. Instead of teeth, modern birds (Neornithes) use a horny beak (rhamphotheca) and a muscular gizzard to acquire and process food. We performed comparative genomic analyses representing lineages of nearly all extant bird orders and recovered shared, inactivating mutations within genes expressed in both the enamel and dentin of teeth of other vertebrate species, indicating that the common ancestor of modern birds lacked mineralized teeth. We estimate that tooth loss, or at least the loss of enamel caps that provide the outer layer of mineralized teeth, occurred about 116 million years ago.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meredith, Robert W -- Zhang, Guojie -- Gilbert, M Thomas P -- Jarvis, Erich D -- Springer, Mark S -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1254390. doi: 10.1126/science.1254390.

Description: Recent discoveries of spectacular dinosaur fossils overwhelmingly support the hypothesis that birds are descended from maniraptoran theropod dinosaurs, and furthermore, demonstrate that distinctive bird characteristics such as feathers, flight, endothermic physiology, unique strategies for reproduction and growth, and a novel pulmonary system originated among Mesozoic terrestrial dinosaurs. The transition from ground-living to flight-capable theropod dinosaurs now probably represents one of the best-documented major evolutionary transitions in life history. Recent studies in developmental biology and other disciplines provide additional insights into how bird characteristics originated and evolved. The iconic features of extant birds for the most part evolved in a gradual and stepwise fashion throughout archosaur evolution. However, new data also highlight occasional bursts of morphological novelty at certain stages particularly close to the origin of birds and an unavoidable complex, mosaic evolutionary distribution of major bird characteristics on the theropod tree. Research into bird origins provides a premier example of how paleontological and neontological data can interact to reveal the complexity of major innovations, to answer key evolutionary questions, and to lead to new research directions. A better understanding of bird origins requires multifaceted and integrative approaches, yet fossils necessarily provide the final test of any evolutionary model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Xing -- Zhou, Zhonghe -- Dudley, Robert -- Mackem, Susan -- Chuong, Cheng-Ming -- Erickson, Gregory M -- Varricchio, David J -- AR 47364/AR/NIAMS NIH HHS/ -- AR 60306/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1253293. doi: 10.1126/science.1253293.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Key Laboratory of Vertebrate Evolution and Human Origins, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing, 100044, PR China. xu.xing@ivpp.ac.cn. ; Key Laboratory of Vertebrate Evolution and Human Origins, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing, 100044, PR China. ; Department of Integrative Biology, University of California, Berkeley, CA 94720, USA. ; Cancer and Developmental Biology Laboratory, Center for Cancer Research, NCI-Frederick NIH, Frederick, MD 21702, USA. ; Department of Pathology, University of Southern California, CA 90033, USA.

Description: Coupled translocation of messenger RNA and transfer RNA (tRNA) through the ribosome, a process catalyzed by elongation factor EF-G, is a crucial step in protein synthesis. The crystal structure of a bacterial translocation complex describes the binding states of two tRNAs trapped in mid-translocation. The deacylated P-site tRNA has moved into a partly translocated pe/E chimeric hybrid state. The anticodon stem-loop of the A-site tRNA is captured in transition toward the 30S P site, while its 3' acceptor end contacts both the A and P loops of the 50S subunit, forming an ap/ap chimeric hybrid state. The structure shows how features of ribosomal RNA rearrange to hand off the A-site tRNA to the P site, revealing an active role for ribosomal RNA in the translocation process.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4242719/" 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/PMC4242719/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Jie -- Lancaster, Laura -- Donohue, John Paul -- Noller, Harry F -- GM-17129/GM/NIGMS NIH HHS/ -- GM59140/GM/NIGMS NIH HHS/ -- R01 GM017129/GM/NIGMS NIH HHS/ -- R01 GM059140/GM/NIGMS NIH HHS/ -- R01 GM105404/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 5;345(6201):1188-91. doi: 10.1126/science.1255030.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Biology of RNA and Department of Molecular, Cell and Developmental Biology, University of California at Santa Cruz, Santa Cruz, CA 95064, USA. ; Center for Molecular Biology of RNA and Department of Molecular, Cell and Developmental Biology, University of California at Santa Cruz, Santa Cruz, CA 95064, USA. harry@nuvolari.ucsc.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25190797" target="_blank"〉PubMed〈/a〉

Description: The yeast mitochondrial ABC transporter Atm1, in concert with glutathione, functions in the export of a substrate required for cytosolic-nuclear iron-sulfur protein biogenesis and cellular iron regulation. Defects in the human ortholog ABCB7 cause the sideroblastic anemia XLSA/A. Here, we report the crystal structures of free and glutathione-bound Atm1 in inward-facing, open conformations at 3.06- and 3.38-angstrom resolution, respectively. The glutathione binding site includes a residue mutated in XLSA/A and is located close to the inner membrane surface in a large cavity. The two nucleotide-free adenosine 5'-triphosphate binding domains do not interact yet are kept in close vicinity through tight interaction of the two C-terminal alpha-helices of the Atm1 dimer. The resulting protein stabilization may be a common structural feature of all ABC exporters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srinivasan, Vasundara -- Pierik, Antonio J -- Lill, Roland -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1137-40. doi: 10.1126/science.1246729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Zytobiologie, Philipps-Universitat Marburg, Robert-Koch-Strasse 6, 35032 Marburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604199" target="_blank"〉PubMed〈/a〉

Description: Rapidly permineralized fossils can provide exceptional insights into the evolution of life over geological time. Here, we present an exquisitely preserved, calcified stem of a royal fern (Osmundaceae) from Early Jurassic lahar deposits of Sweden in which authigenic mineral precipitation from hydrothermal brines occurred so rapidly that it preserved cytoplasm, cytosol granules, nuclei, and even chromosomes in various stages of cell division. Morphometric parameters of interphase nuclei match those of extant Osmundaceae, indicating that the genome size of these reputed "living fossils" has remained unchanged over at least 180 million years-a paramount example of evolutionary stasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bomfleur, Benjamin -- McLoughlin, Stephen -- Vajda, Vivi -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1376-7. doi: 10.1126/science.1249884.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Palaeobiology, Swedish Museum of Natural History, Post Office Box 50007, SE-104 05 Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653037" target="_blank"〉PubMed〈/a〉

Description: The evolution of the ratite birds has been widely attributed to vicariant speciation, driven by the Cretaceous breakup of the supercontinent Gondwana. The early isolation of Africa and Madagascar implies that the ostrich and extinct Madagascan elephant birds (Aepyornithidae) should be the oldest ratite lineages. We sequenced the mitochondrial genomes of two elephant birds and performed phylogenetic analyses, which revealed that these birds are the closest relatives of the New Zealand kiwi and are distant from the basal ratite lineage of ostriches. This unexpected result strongly contradicts continental vicariance and instead supports flighted dispersal in all major ratite lineages. We suggest that convergence toward gigantism and flightlessness was facilitated by early Tertiary expansion into the diurnal herbivory niche after the extinction of the dinosaurs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitchell, Kieren J -- Llamas, Bastien -- Soubrier, Julien -- Rawlence, Nicolas J -- Worthy, Trevor H -- Wood, Jamie -- Lee, Michael S Y -- Cooper, Alan -- New York, N.Y. -- Science. 2014 May 23;344(6186):898-900. doi: 10.1126/science.1251981.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Centre for Ancient DNA, School of Earth and Environmental Sciences, University of Adelaide, North Terrace Campus, South Australia 5005, Australia. ; School of Biological Sciences, Flinders University, South Australia 5001, Australia. ; Landcare Research, Post Office Box 40, Lincoln 7640, New Zealand. ; Australian Centre for Ancient DNA, School of Earth and Environmental Sciences, University of Adelaide, North Terrace Campus, South Australia 5005, Australia.

Description: The extent to which biodiversity change in local assemblages contributes to global biodiversity loss is poorly understood. We analyzed 100 time series from biomes across Earth to ask how diversity within assemblages is changing through time. We quantified patterns of temporal alpha diversity, measured as change in local diversity, and temporal beta diversity, measured as change in community composition. Contrary to our expectations, we did not detect systematic loss of alpha diversity. However, community composition changed systematically through time, in excess of predictions from null models. Heterogeneous rates of environmental change, species range shifts associated with climate change, and biotic homogenization may explain the different patterns of temporal alpha and beta diversity. Monitoring and understanding change in species composition should be a conservation priority.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dornelas, Maria -- Gotelli, Nicholas J -- McGill, Brian -- Shimadzu, Hideyasu -- Moyes, Faye -- Sievers, Caya -- Magurran, Anne E -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):296-9. doi: 10.1126/science.1248484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Biological Diversity and Scottish Oceans Institute, School of Biology, University of St. Andrews, St. Andrews, Fife KY16 9TH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744374" target="_blank"〉PubMed〈/a〉

Description: Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores have substantial effects on the structure and function of diverse ecosystems. Significant cascading trophic interactions, mediated by their prey or sympatric mesopredators, arise when some of these carnivores are extirpated from or repatriated to ecosystems. Unexpected effects of trophic cascades on various taxa and processes include changes to bird, mammal, invertebrate, and herpetofauna abundance or richness; subsidies to scavengers; altered disease dynamics; carbon sequestration; modified stream morphology; and crop damage. Promoting tolerance and coexistence with large carnivores is a crucial societal challenge that will ultimately determine the fate of Earth's largest carnivores and all that depends upon them, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ripple, William J -- Estes, James A -- Beschta, Robert L -- Wilmers, Christopher C -- Ritchie, Euan G -- Hebblewhite, Mark -- Berger, Joel -- Elmhagen, Bodil -- Letnic, Mike -- Nelson, Michael P -- Schmitz, Oswald J -- Smith, Douglas W -- Wallach, Arian D -- Wirsing, Aaron J -- New York, N.Y. -- Science. 2014 Jan 10;343(6167):1241484. doi: 10.1126/science.1241484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Trophic Cascades Program, Department of Forest Ecosystems and Society, Oregon State University, Corvallis, OR 97331, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24408439" target="_blank"〉PubMed〈/a〉

Description: Lineage-specific stem cells are critical for the production and maintenance of specific cell types and tissues in multicellular organisms. In Arabidopsis, the initiation and proliferation of stomatal lineage cells is controlled by the basic helix-loop-helix transcription factor SPEECHLESS (SPCH). SPCH-driven asymmetric and self-renewing divisions allow flexibility in stomatal production and overall organ growth. How SPCH directs stomatal lineage cell behaviors, however, is unclear. Here, we improved the chromatin immunoprecipitation (ChIP) assay and profiled the genome-wide targets of Arabidopsis SPCH in vivo. We found that SPCH controls key regulators of cell fate and asymmetric cell divisions and modulates responsiveness to peptide and phytohormone-mediated intercellular communication. Our results delineate the molecular pathways that regulate an essential adult stem cell lineage in plants.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4390554/" 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/PMC4390554/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lau, On Sun -- Davies, Kelli A -- Chang, Jessica -- Adrian, Jessika -- Rowe, Matthew H -- Ballenger, Catherine E -- Bergmann, Dominique C -- 1R01GM086632/GM/NIGMS NIH HHS/ -- 5T32GM007276/GM/NIGMS NIH HHS/ -- R01 GM086632/GM/NIGMS NIH HHS/ -- T32 GM007276/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Sep 26;345(6204):1605-9. doi: 10.1126/science.1256888.

Description: The origin of chordates has been debated for more than a century, with one key issue being the emergence of the notochord. In vertebrates, the notochord develops by convergence and extension of the chordamesoderm, a population of midline cells of unique molecular identity. We identify a population of mesodermal cells in a developing invertebrate, the marine annelid Platynereis dumerilii, that converges and extends toward the midline and expresses a notochord-specific combination of genes. These cells differentiate into a longitudinal muscle, the axochord, that is positioned between central nervous system and axial blood vessel and secretes a strong collagenous extracellular matrix. Ancestral state reconstruction suggests that contractile mesodermal midline cells existed in bilaterian ancestors. We propose that these cells, via vacuolization and stiffening, gave rise to the chordate notochord.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lauri, Antonella -- Brunet, Thibaut -- Handberg-Thorsager, Mette -- Fischer, Antje H L -- Simakov, Oleg -- Steinmetz, Patrick R H -- Tomer, Raju -- Keller, Philipp J -- Arendt, Detlev -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1365-8. doi: 10.1126/science.1253396.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Biology Unit, European Molecular Biology Laboratory (EMBL), D-69117 Heidelberg. ; Developmental Biology Unit, European Molecular Biology Laboratory (EMBL), D-69117 Heidelberg.

Description: Two categories of evolutionary challenges result from escalating human impacts on the planet. The first arises from cancers, pathogens, and pests that evolve too quickly and the second, from the inability of many valued species to adapt quickly enough. Applied evolutionary biology provides a suite of strategies to address these global challenges that threaten human health, food security, and biodiversity. This Review highlights both progress and gaps in genetic, developmental, and environmental manipulations across the life sciences that either target the rate and direction of evolution or reduce the mismatch between organisms and human-altered environments. Increased development and application of these underused tools will be vital in meeting current and future targets for sustainable development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4245030/" 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/PMC4245030/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carroll, Scott P -- Jorgensen, Peter Sogaard -- Kinnison, Michael T -- Bergstrom, Carl T -- Denison, R Ford -- Gluckman, Peter -- Smith, Thomas B -- Strauss, Sharon Y -- Tabashnik, Bruce E -- U54 GM088558/GM/NIGMS NIH HHS/ -- U54GM088558/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):1245993. doi: 10.1126/science.1245993.

Description: The human sense of fairness is an evolutionary puzzle. To study this, we can look to other species, in which this can be translated empirically into responses to reward distribution. Passive and active protest against receiving less than a partner for the same task is widespread in species that cooperate outside kinship and mating bonds. There is less evidence that nonhuman species seek to equalize outcomes to their own detriment, yet the latter has been documented in our closest relatives, the apes. This reaction probably reflects an attempt to forestall partner dissatisfaction with obtained outcomes and its negative impact on future cooperation. We hypothesize that it is the evolution of this response that allowed the development of a complete sense of fairness in humans, which aims not at equality for its own sake but for the sake of continued cooperation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451566/" 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/PMC4451566/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brosnan, Sarah F -- de Waal, Frans B M -- P51 OD011132/OD/NIH HHS/ -- P51 RR000165/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):1251776. doi: 10.1126/science.1251776.

Description: Lordkipanidze et al. (Research Article, 18 October 2013, p. 326) conclude, from gross morphological comparisons and geometric-morphometric analysis of general shape, that the five hominid crania from Dmanisi in Georgia represent a single regional variant of Homo erectus. However, dental, mandibular, and cranial morphologies all suggest taxic diversity and, in particular, validate the previously named H. georgicus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartz, Jeffrey H -- Tattersall, Ian -- Chi, Zhang -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):360. doi: 10.1126/science.1250056.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Pittsburgh, Pittsburgh, PA 15260, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763572" target="_blank"〉PubMed〈/a〉

Description: Because of differences in craniofacial morphology and dentition between the earliest American skeletons and modern Native Americans, separate origins have been postulated for them, despite genetic evidence to the contrary. We describe a near-complete human skeleton with an intact cranium and preserved DNA found with extinct fauna in a submerged cave on Mexico's Yucatan Peninsula. This skeleton dates to between 13,000 and 12,000 calendar years ago and has Paleoamerican craniofacial characteristics and a Beringian-derived mitochondrial DNA (mtDNA) haplogroup (D1). Thus, the differences between Paleoamericans and Native Americans probably resulted from in situ evolution rather than separate ancestry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chatters, James C -- Kennett, Douglas J -- Asmerom, Yemane -- Kemp, Brian M -- Polyak, Victor -- Blank, Alberto Nava -- Beddows, Patricia A -- Reinhardt, Eduard -- Arroyo-Cabrales, Joaquin -- Bolnick, Deborah A -- Malhi, Ripan S -- Culleton, Brendan J -- Erreguerena, Pilar Luna -- Rissolo, Dominique -- Morell-Hart, Shanti -- Stafford, Thomas W Jr -- New York, N.Y. -- Science. 2014 May 16;344(6185):750-4. doi: 10.1126/science.1252619.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Applied Paleoscience and DirectAMS, 10322 NE 190th Street, Bothell, WA 98011, USA. paleosci@gmail.com. ; Department of Anthropology and Institutes of Energy and the Environment, Pennsylvania State University, University Park, PA 16802, USA. ; Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, NM 87131-0001, USA. ; Department of Anthropology and School of Biological Sciences, Washington State University, Pullman, WA 99164, USA. ; Bay Area Underwater Explorers, Berkeley, CA, USA. ; Department of Earth and Planetary Sciences, Northwestern University, Evanston, IL 60208, USA. ; School of Geography and Earth Sciences, McMaster University, Hamilton, Ontario L8S 4K1, Canada. ; Instituto Nacional Antropologia e Historia, Colonia Centro Historico, 06060, Mexico City, DF, Mexico. ; Department of Anthropology and Population Research Center, University of Texas at Austin, Austin, TX 78712, USA. ; Institute for Genomic Biology, University of Illinois, Urbana-Champaign, IL 61801, USA. ; Subdireccion de Arqueologia Subacuatica, Instituto Nacional de Antropologia e Historia, 06070 Mexico City, Mexico. ; Waitt Institute, La Jolla, CA 92038-1948, USA. ; Department of Anthropology, Stanford University, Stanford, CA 94305, USA. ; Centre for AMS C, Department of Physics and Astronomy, Aarhus University, Aarhus, Denmark, and Centre for GeoGenetics, Natural History Museum of Denmark, Geological Museum, Copenhagen, Denmark.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24833392" target="_blank"〉PubMed〈/a〉

Description: The 18-kilodalton translocator protein TSPO is found in mitochondrial membranes and mediates the import of cholesterol and porphyrins into mitochondria. In line with the role of TSPO in mitochondrial function, TSPO ligands are used for a variety of diagnostic and therapeutic applications in animals and humans. We present the three-dimensional high-resolution structure of mammalian TSPO reconstituted in detergent micelles in complex with its high-affinity ligand PK11195. The TSPO-PK11195 structure is described by a tight bundle of five transmembrane alpha helices that form a hydrophobic pocket accepting PK11195. Ligand-induced stabilization of the structure of TSPO suggests a molecular mechanism for the stimulation of cholesterol transport into mitochondria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jaremko, Lukasz -- Jaremko, Mariusz -- Giller, Karin -- Becker, Stefan -- Zweckstetter, Markus -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1363-6. doi: 10.1126/science.1248725.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Biophysikalische Chemie, 37077 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653034" target="_blank"〉PubMed〈/a〉

Description: The Lower to Middle Paleolithic transition (~400,000 to 200,000 years ago) is marked by technical, behavioral, and anatomical changes among hominin populations throughout Africa and Eurasia. The replacement of bifacial stone tools, such as handaxes, by tools made on flakes detached from Levallois cores documents the most important conceptual shift in stone tool production strategies since the advent of bifacial technology more than one million years earlier and has been argued to result from the expansion of archaic Homo sapiens out of Africa. Our data from Nor Geghi 1, Armenia, record the earliest synchronic use of bifacial and Levallois technology outside Africa and are consistent with the hypothesis that this transition occurred independently within geographically dispersed, technologically precocious hominin populations with a shared technological ancestry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, D S -- Wilkinson, K N -- Blockley, S -- Mark, D F -- Pinhasi, R -- Schmidt-Magee, B A -- Nahapetyan, S -- Mallol, C -- Berna, F -- Glauberman, P J -- Raczynski-Henk, Y -- Wales, N -- Frahm, E -- Joris, O -- MacLeod, A -- Smith, V C -- Cullen, V L -- Gasparian, B -- New York, N.Y. -- Science. 2014 Sep 26;345(6204):1609-13. doi: 10.1126/science.1256484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Connecticut, 354 Mansfield Road, Unit 1176, Storrs, CT 06269, USA. daniel.adler@uconn.edu. ; Department of Archaeology, University of Winchester, Winchester, SO22 4NR, UK. ; Department of Geography, Royal Holloway, University of London, Egham, Surrey, TW20 0EX, UK. ; Natural Environmental Research Council Argon Isotope Facility, Scottish Universities Environmental Research Centre, Scottish Enterprise and Technology Park, Rankine Avenue, East Kilbride, G75 0QF, UK. ; School of Archaeology, University College Dublin, Newman Building, Belfield, Dublin 4, Ireland. ; Department of Anthropology, University of Connecticut, 354 Mansfield Road, Unit 1176, Storrs, CT 06269, USA. ; Department of Cartography and Geomorphology, Yerevan State University, Alek Manukyan 1, 0025 Yerevan, Armenia. ; Departamento de Geografia e Historia, Universidad de La Laguna, Tenerife, Spain. ; Department of Archaeology, Simon Fraser University, 8888 University Drive, Burnaby, British Columbia, V5A 1S6, Canada. ; Ex-Situ Silex, Leiden, Netherlands. ; Department of Anthropology, University of Connecticut, 354 Mansfield Road, Unit 1176, Storrs, CT 06269, USA.

Description: Male mammals often kill conspecific offspring. The benefits of such infanticide to males, and its costs to females, probably vary across mammalian social and mating systems. We used comparative analyses to show that infanticide primarily evolves in social mammals in which reproduction is monopolized by a minority of males. It has not promoted social counterstrategies such as female gregariousness, pair living, or changes in group size and sex ratio, but is successfully prevented by female sexual promiscuity, a paternity dilution strategy. These findings indicate that infanticide is a consequence, rather than a cause, of contrasts in mammalian social systems affecting the intensity of sexual conflict.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lukas, Dieter -- Huchard, Elise -- New York, N.Y. -- Science. 2014 Nov 14;346(6211):841-4. doi: 10.1126/science.1257226.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Large Animal Research Group, Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK. dl384@cam.ac.uk. ; Large Animal Research Group, Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK.

Description: Little is known about the genetic basis of convergent traits that originate repeatedly over broad taxonomic scales. The myogenic electric organ has evolved six times in fishes to produce electric fields used in communication, navigation, predation, or defense. We have examined the genomic basis of the convergent anatomical and physiological origins of these organs by assembling the genome of the electric eel (Electrophorus electricus) and sequencing electric organ and skeletal muscle transcriptomes from three lineages that have independently evolved electric organs. Our results indicate that, despite millions of years of evolution and large differences in the morphology of electric organ cells, independent lineages have leveraged similar transcription factors and developmental and cellular pathways in the evolution of electric organs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallant, Jason R -- Traeger, Lindsay L -- Volkening, Jeremy D -- Moffett, Howell -- Chen, Po-Hao -- Novina, Carl D -- Phillips, George N Jr -- Anand, Rene -- Wells, Gregg B -- Pinch, Matthew -- Guth, Robert -- Unguez, Graciela A -- Albert, James S -- Zakon, Harold H -- Samanta, Manoj P -- Sussman, Michael R -- 1SC1GM092297-01A1/GM/NIGMS NIH HHS/ -- R01 GM084879/GM/NIGMS NIH HHS/ -- R01 GM088670/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1522-5. doi: 10.1126/science.1254432.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Michigan State University, East Lansing, MI 48824, USA.

To test the combined effects of ecological and evolutionary forces on host-pathogen systems, we analyzed the spatiotemporal dynamics of a plant (Plantago lanceolata)-fungal pathogen (Podosphaera plantaginis)relationship for 12 years in over 4000 host populations. Disease prevalence at the metapopulation level was low, with high annual pathogen extinction rates balanced by frequent (re-)colonizations. Highly connected host populations experienced less pathogen colonization and higher pathogen extinction rates than expected; a laboratory assay confirmed that this phenomenon was caused by higher levels of disease resistance in highly connected host populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jousimo, Jussi -- Tack, Ayco J M -- Ovaskainen, Otso -- Mononen, Tommi -- Susi, Hanna -- Tollenaere, Charlotte -- Laine, Anna-Liisa -- New York, N.Y. -- Science. 2014 Jun 13;344(6189):1289-93. doi: 10.1126/science.1253621.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Metapopulation Research Group, Department of Biosciences, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FI-00014 University of Helsinki, Helsinki, Finland. ; Metapopulation Research Group, Department of Biosciences, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FI-00014 University of Helsinki, Helsinki, Finland.

Description: Based on nuclear and mitochondrial DNA, Hailer et al. (Reports, 20 April 2012, p. 344) suggested early divergence of polar bears from a common ancestor with brown bears and subsequent introgression. Our population genetic analysis that traces each of the genealogies in the independent nuclear loci does not support the evolutionary model proposed by the authors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakagome, Shigeki -- Mano, Shuhei -- Hasegawa, Masami -- New York, N.Y. -- Science. 2013 Mar 29;339(6127):1522. doi: 10.1126/science.1227339.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Statistical Mathematics, Tachikawa, Tokyo, Japan. nakagome@ism.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23539580" target="_blank"〉PubMed〈/a〉
