    Description: Observations of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) provide valuable comparative data for understanding the significance of conspecific killing. Two kinds of hypothesis have been proposed. Lethal violence is sometimes concluded to be the result of adaptive strategies, such that killers ultimately gain fitness benefits by increasing their access to resources such as food or mates. Alternatively, it could be a non-adaptive result of human impacts, such as habitat change or food provisioning. To discriminate between these hypotheses we compiled information from 18 chimpanzee communities and 4 bonobo communities studied over five decades. Our data include 152 killings (n = 58 observed, 41 inferred, and 53 suspected killings) by chimpanzees in 15 communities and one suspected killing by bonobos. We found that males were the most frequent attackers (92% of participants) and victims (73%); most killings (66%) involved intercommunity attacks; and attackers greatly outnumbered their victims (median 8:1 ratio). Variation in killing rates was unrelated to measures of human impacts. Our results are compatible with previously proposed adaptive explanations for killing by chimpanzees, whereas the human impact hypothesis is not supported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Michael L -- Boesch, Christophe -- Fruth, Barbara -- Furuichi, Takeshi -- Gilby, Ian C -- Hashimoto, Chie -- Hobaiter, Catherine L -- Hohmann, Gottfried -- Itoh, Noriko -- Koops, Kathelijne -- Lloyd, Julia N -- Matsuzawa, Tetsuro -- Mitani, John C -- Mjungu, Deus C -- Morgan, David -- Muller, Martin N -- Mundry, Roger -- Nakamura, Michio -- Pruetz, Jill -- Pusey, Anne E -- Riedel, Julia -- Sanz, Crickette -- Schel, Anne M -- Simmons, Nicole -- Waller, Michel -- Watts, David P -- White, Frances -- Wittig, Roman M -- Zuberbuhler, Klaus -- Wrangham, Richard W -- R01 AI 058715/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Sep 18;513(7518):414-7. doi: 10.1038/nature13727.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Department of Anthropology, University of Minnesota, 395 Humphrey Center, 301 19th Avenue South, Minneapolis, Minnesota 55455, USA [2] Department of Ecology, Evolution and Behavior, University of Minnesota, 1987 Upper Buford Circle, St Paul, Minnesota 55108, USA. ; Department of Primatology, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany. ; 1] Division of Neurobiology, Ludwig-Maximilians Universitaet Muenchen, Germany [2] Centre for Research and Conservation, Royal Zoological Society of Antwerp, Belgium. ; Primate Research Institute, Kyoto University, 41-2 Kanrin, Inuyama, Aichi 484-8506, Japan. ; 1] Department of Evolutionary Anthropology, Duke University, 104 Biological Sciences Building, Box 90383, Durham, North Carolina 27708-0680, USA [2] School of Human Evolution and Social Change, Arizona State University, PO Box 872402, Tempe, Arizona 85287-2402, USA. ; School of Psychology and Neuroscience, University of St Andrews, Westburn Lane, St Andrews, Fife KY16 9JP, UK. ; Wildlife Research Center, Kyoto University, 2-24 Tanaka-Sekiden-Cho, Sakyo, Kyoto, Japan. ; Division of Biological Anthropology, Department of Archaeology &Anthropology, University of Cambridge, Henry Wellcome Building, Fitzwilliam Street, Cambridge CB2 1QH, UK. ; Zoology Department, Makerere University, P.O.

    Description: The coxa-trochanteral joints on the legs of the weevil Trigonopterus oblongus (Pascoe) work as a biological screw-and-nut system. The apical portions of the coxae closely resemble nuts with well-defined inner threads covering 345 degrees . The corresponding trochanters have perfectly compatible external spiral threads of 410 degrees .〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van de Kamp, Thomas -- Vagovic, Patrik -- Baumbach, Tilo -- Riedel, Alexander -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):52. doi: 10.1126/science.1204245.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ANKA-Institute for Synchrotron Radiation, Karlsruhe Institute of Technology, D-76344 Eggenstein-Leopoldshafen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21719669" target="_blank"〉PubMed〈/a〉

    Description: Recent studies have shown that the diffusivity of enzymes increases in a substrate-dependent manner during catalysis. Although this observation has been reported and characterized for several different systems, the precise origin of this phenomenon is unknown. Calorimetric methods are often used to determine enthalpies from enzyme-catalysed reactions and can therefore provide important insight into their reaction mechanisms. The ensemble averages involved in traditional bulk calorimetry cannot probe the transient effects that the energy exchanged in a reaction may have on the catalyst. Here we obtain single-molecule fluorescence correlation spectroscopy data and analyse them within the framework of a stochastic theory to demonstrate a mechanistic link between the enhanced diffusion of a single enzyme molecule and the heat released in the reaction. We propose that the heat released during catalysis generates an asymmetric pressure wave that results in a differential stress at the protein-solvent interface that transiently displaces the centre-of-mass of the enzyme (chemoacoustic effect). This novel perspective on how enzymes respond to the energy released during catalysis suggests a possible effect of the heat of reaction on the structural integrity and internal degrees of freedom of the enzyme.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4363105/" 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/PMC4363105/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riedel, Clement -- Gabizon, Ronen -- Wilson, Christian A M -- Hamadani, Kambiz -- Tsekouras, Konstantinos -- Marqusee, Susan -- Presse, Steve -- Bustamante, Carlos -- R01 GM050945/GM/NIGMS NIH HHS/ -- R01 GM065050/GM/NIGMS NIH HHS/ -- R01-GM0325543/GM/NIGMS NIH HHS/ -- R01-GM05945/GM/NIGMS NIH HHS/ -- R01-GM65050/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jan 8;517(7533):227-30. doi: 10.1038/nature14043.

    Description: Cellular membrane fusion is thought to proceed through intermediates including docking of apposed lipid bilayers, merging of proximal leaflets to form a hemifusion diaphragm, and fusion pore opening. A membrane-bridging four-helix complex of soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) mediates fusion. However, how assembly of the SNARE complex generates docking and other fusion intermediates is unknown. Using a cell-free reaction, we identified intermediates visually and then arrested the SNARE fusion machinery when fusion was about to begin. Partial and directional assembly of SNAREs tightly docked bilayers, but efficient fusion and an extended form of hemifusion required assembly beyond the core complex to the membrane-connecting linkers. We propose that straining of lipids at the edges of an extended docking zone initiates fusion.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3677693/" 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/PMC3677693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hernandez, Javier M -- Stein, Alexander -- Behrmann, Elmar -- Riedel, Dietmar -- Cypionka, Anna -- Farsi, Zohreh -- Walla, Peter J -- Raunser, Stefan -- Jahn, Reinhard -- 3P01GM072694-05S1/GM/NIGMS NIH HHS/ -- P01 GM072694/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1581-4. doi: 10.1126/science.1221976.
