    Description: Separation and purification are critical industrial processes for separating components of chemical mixtures, and these processes account for about half of industrial energy usage (1). Gas mixtures of compounds with very similar physical properties are particularly difficult to separate. On pages 137 and 141 of this issue, Cadiau et al. (2) and Cui et al. (3), respectively, show that microporous materials can be designed to have high adsorption capacity and selectivity for particular hydrocarbons, enabling energy-efficient separation. Author: Jerry Y.

    Description: Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes. LPMOs are of interest to biotechnology because efficient depolymerization of cellulose is a major bottleneck for the production of biologically based chemicals and fuels. On page 1098 of this issue, Kracher et al. (1) compare LPMO-reducing substrates in fungi from different taxonomic groups and lifestyles, based on both biochemical and genomic evidence. The results provide insights into reductive activation of LPMO that are important for developing more efficient industrial enzymes for lignocellulose biorefineries. Author: Angel T. Martínez

    Description: Two teams have developed innovative new applications of the popular genome-editing method CRISPR. One of the groups has used it to mark and trace cells in a developing animal. In the method's first test, described online today in Science, the researchers reveal that many tissues and organs in adult zebrafish form from just a few embryonic cells. Other researchers are already looking to adapt the method to mice, or to exploit it to trace the evolution of tumors. The second group found a way to use CRISPR-guided mutations to record a cell's history—for example, the environmental signals that influence it. Author: Kai Kupferschmidt

    Description: The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale.

    Description: Labinger argues that stepwise reaction of methane with water to produce methanol and hydrogen will never be commercially feasible because of its substoichiometric basis with respect to the active site and the requirement of a large temperature swing. This comment is not touching any new ground, beyond describing the thermodynamic feasibility, thermal cycling, and the role of water as discussed previously. Most important, it does not have a solid numerical basis.

    Description: Vinyl carbocations have been the subject of extensive experimental and theoretical studies over the past five decades. Despite this long history in chemistry, the utility of vinyl cations in chemical synthesis has been limited, with most reactivity studies focusing on solvolysis reactions or intramolecular processes. Here we report synthetic and mechanistic studies of vinyl cations generated through silylium–weakly coordinating anion catalysis. We find that these reactive intermediates undergo mild intermolecular carbon-carbon bond–forming reactions, including carbon-hydrogen (C–H) insertion into unactivated sp 3 C–H bonds and reductive Friedel-Crafts reactions with arenes. Moreover, we conducted computational studies of these alkane C–H functionalization reactions and discovered that they proceed through nonclassical, ambimodal transition structures. This reaction manifold provides a framework for the catalytic functionalization of hydrocarbons using simple ketone derivatives.

    Description: It is commonly assumed that recognition and discrimination of chirality, both in nature and in artificial systems, depend solely on spatial effects. However, recent studies have suggested that charge redistribution in chiral molecules manifests an enantiospecific preference in electron spin orientation. We therefore reasoned that the induced spin polarization may affect enantiorecognition through exchange interactions. Here we show experimentally that the interaction of chiral molecules with a perpendicularly magnetized substrate is enantiospecific. Thus, one enantiomer adsorbs preferentially when the magnetic dipole is pointing up, whereas the other adsorbs faster for the opposite alignment of the magnetization. The interaction is not controlled by the magnetic field per se, but rather by the electron spin orientations, and opens prospects for a distinct approach to enantiomeric separations.

    Description: Theory has established the importance of geometric phase (GP) effects in the adiabatic dynamics of molecular systems with a conical intersection connecting the ground- and excited-state potential energy surfaces, but direct observation of their manifestation in chemical reactions remains a major challenge. Here, we report a high-resolution crossed molecular beams study of the H + HD -〉 H 2 + D reaction at a collision energy slightly above the conical intersection. Velocity map ion imaging revealed fast angular oscillations in product quantum state–resolved differential cross sections in the forward scattering direction for H 2 products at specific rovibrational levels. The experimental results agree with adiabatic quantum dynamical calculations only when the GP effect is included.

    Description: Mutations in the fragile X mental retardation 1 gene ( FMR1 ) cause the most common inherited human autism spectrum disorder. FMR1 influences messenger RNA (mRNA) translation, but identifying functional targets has been difficult. We analyzed quiescent Drosophila oocytes, which, like neural synapses, depend heavily on translating stored mRNA. Ribosome profiling revealed that FMR1 enhances rather than represses the translation of mRNAs that overlap previously identified FMR1 targets, and acts preferentially on large proteins. Human homologs of at least 20 targets are associated with dominant intellectual disability, and 30 others with recessive neurodevelopmental dysfunction. Stored oocytes lacking FMR1 usually generate embryos with severe neural defects, unlike stored wild-type oocytes, which suggests that translation of multiple large proteins by stored mRNAs is defective in fragile X syndrome and possibly other autism spectrum disorders.

    Description: The chemistry of the carbonyl group is essential to modern organic synthesis. The preparation of substituted, enantioenriched 1,3- or 1,5-dicarbonyls is well developed, as their disconnection naturally follows from the intrinsic polarity of the carbonyl group. By contrast, a general enantioselective access to quaternary stereocenters in acyclic 1,4-dicarbonyl systems remains an unresolved problem, despite the tremendous importance of 2,3-substituted 1,4-dicarbonyl motifs in natural products and drug scaffolds. Here we present a broad enantioselective and stereodivergent strategy to access acyclic, polysubstituted 1,4-dicarbonyls via acid-catalyzed [3,3]-sulfonium rearrangement starting from vinyl sulfoxides and ynamides. The stereochemistry at sulfur governs the absolute sense of chiral induction, whereas the double bond geometry dictates the relative configuration of the final products.

    Description: With the recent soaring production of natural gas, the use of methane and other light hydrocarbon feedstocks as starting materials in synthetic transformations is becoming increasingly economically attractive, although it remains chemically challenging. We report the development of photocatalytic C–H amination, alkylation, and arylation of methane, ethane, and higher alkanes under visible light irradiation at ambient temperature. High catalytic efficiency (turnover numbers up to 2900 for methane and 9700 for ethane) and selectivity were achieved using abundant, inexpensive cerium salts as photocatalysts. Ligand-to-metal charge transfer excitation generated alkoxy radicals from simple alcohols that in turn acted as hydrogen atom transfer catalysts. The mixed-phase gas/liquid reaction was adapted to continuous flow, enabling the efficient use of gaseous feedstocks in scalable photocatalytic transformations.

    Description: Intrigued by the potential of nanoscale machines, scientists have long attempted to control molecular motion. We monitored the individual 0.7-nanometer steps of a single molecular hopper as it moved in an electric field along a track in a nanopore controlled by a chemical ratchet. The hopper demonstrated characteristics desired in a moving molecule: defined start and end points, processivity, no chemical fuel requirement, directional motion, and external control. The hopper was readily functionalized to carry cargos. For example, a DNA molecule could be ratcheted along the track in either direction, a prerequisite for nanopore sequencing.

    Description: Phosphorothioate nucleotides have emerged as powerful pharmacological substitutes of their native phosphodiester analogs with important translational applications in antisense oligonucleotide (ASO) therapeutics and cyclic dinucleotide (CDN) synthesis. Stereocontrolled installation of this chiral motif has long been hampered by the systemic use of phosphorus(III) [P(III)]–based reagent systems as the sole practical means of oligonucleotide assembly. A fundamentally different approach is described herein: the invention of a P(V)-based reagent platform for programmable, traceless, diastereoselective phosphorus-sulfur incorporation. The power of this reagent system is demonstrated through the robust and stereocontrolled synthesis of various nucleotidic architectures, including ASOs and CDNs, via an efficient, inexpensive, and operationally simple protocol.

    Description: Here we report an anomalous porous molecular crystal built of C–H···N-bonded double-layered roof-floor components and wall components of a segregatively interdigitated architecture. This complicated porous structure consists of only one type of fully aromatic multijoint molecule carrying three identical dipyridylphenyl wedges. Despite its high symmetry, this molecule accomplishes difficult tasks by using two of its three wedges for roof-floor formation and using its other wedge for wall formation. Although a C–H···N bond is extremely labile, the porous crystal maintains its porosity until thermal breakdown of the C–H···N bonds at 202°C occurs, affording a nonporous polymorph. Though this nonporous crystal survives even at 325°C, it can retrieve the parent porosity under acetonitrile vapor. These findings show how one can translate simplicity into ultrahigh complexity.

    Description: Some of the simplest and most powerful carbon-carbon bond forming strategies take advantage of readily accessible ubiquitous motifs: carbonyls and olefins. Here we report a fundamentally distinct mode of reactivity between carbonyls and olefins that differs from established acid-catalyzed carbonyl-ene, Prins, and carbonyl-olefin metathesis reaction paths. A range of epsilon, zeta-unsaturated ketones undergo Brønsted acid–catalyzed intramolecular cyclization to provide tetrahydrofluorene products via the formation of two new carbon-carbon bonds. Theoretical calculations and accompanying mechanistic studies suggest that this carbocyclization reaction proceeds through the intermediacy of a transient oxetane formed by oxygen atom transfer. The complex polycyclic frameworks in this product class appear as common substructures in organic materials, bioactive natural products, and recently developed pharmaceuticals.

    Description: Alkene aminoarylation with a single, bifunctional reagent is a concise synthetic strategy. We report a catalytic protocol for the addition of arylsulfonylacetamides across electron-rich alkenes with complete anti-Markovnikov regioselectivity and excellent diastereoselectivity to provide 2,2-diarylethylamines. In this process, single-electron alkene oxidation enables carbon-nitrogen bond formation to provide a key benzylic radical poised for a Smiles-Truce 1,5-aryl shift. This reaction is redox-neutral, exhibits broad functional group compatibility, and occurs at room temperature with loss of sulfur dioxide. As this process is driven by visible light, uses readily available starting materials, and demonstrates convergent synthesis, it is well suited for use in a variety of synthetic endeavors.

    Description: Photocatalysis based on optically active, "plasmonic" metal nanoparticles has emerged as a promising approach to facilitate light-driven chemical conversions under far milder conditions than thermal catalysis. However, an understanding of the relation between thermal and electronic excitations has been lacking. We report the substantial light-induced reduction of the thermal activation barrier for ammonia decomposition on a plasmonic photocatalyst. We introduce the concept of a light-dependent activation barrier to account for the effect of light illumination on electronic and thermal excitations in a single unified picture. This framework provides insight into the specific role of hot carriers in plasmon-mediated photochemistry, which is critically important for designing energy-efficient plasmonic photocatalysts.

    Description: Single-electron reduction of a carbonyl to a ketyl enables access to a polarity-reversed platform of reactivity for this cornerstone functional group. However, the synthetic utility of the ketyl radical is hindered by the strong reductants necessary for its generation, which also limit its reactivity to net reductive mechanisms. We report a strategy for net redox-neutral generation and reaction of ketyl radicals. The in situ conversion of aldehydes to α-acetoxy iodides lowers their reduction potential by more than 1 volt, allowing for milder access to the corresponding ketyl radicals and an oxidative termination event. Upon subjecting these iodides to a dimanganese decacarbonyl precatalyst and visible light irradiation, an atom transfer radical addition (ATRA) mechanism affords a broad scope of vinyl iodide products with high Z -selectivity.

    Description: Reactions that form a product with the same reactive functionality as that of one of the starting compounds frequently end in oligomerization. As a salient example, selective aldol coupling of the smallest, though arguably most useful, enolizable aldehyde, acetaldehyde, with just one partner substrate has proven to be extremely challenging. Here, we report a highly enantioselective Mukaiyama aldol reaction with the simple triethylsilyl (TES) and tert -butyldimethylsilyl (TBS) enolates of acetaldehyde and various aliphatic and aromatic acceptor aldehydes. The reaction is catalyzed by recently developed, strongly acidic imidodiphosphorimidates (IDPi), which, like enzymes, display a confined active site but, like small-molecule catalysts, have a broad substrate scope. The process is scalable, fast, efficient (0.5 to 1.5 mole % catalyst loading), and greatly simplifies access to highly valuable silylated acetaldehyde aldols.

    Description: Single-molecule magnets (SMMs) containing only one metal center may represent the lower size limit for molecule-based magnetic information storage materials. Their current drawback is that all SMMs require liquid-helium cooling to show magnetic memory effects. We now report a chemical strategy to access the dysprosium metallocene cation [(Cp i Pr5 )Dy(Cp*)] + (Cp i Pr5 , penta-iso-propylcyclopentadienyl; Cp *, pentamethylcyclopentadienyl), which displays magnetic hysteresis above liquid-nitrogen temperatures. An effective energy barrier to reversal of the magnetization of U eff = 1541 wave number is also measured. The magnetic blocking temperature of T B = 80 kelvin for this cation overcomes an essential barrier toward the development of nanomagnet devices that function at practical temperatures.

    Description: Penguin feathers are highly modified in form and function, but there have been no fossils to inform their evolution. A giant penguin with feathers was recovered from the late Eocene (~36 million years ago) of Peru. The fossil reveals that key feathering features, including undifferentiated primary wing feathers and broad body contour feather shafts, evolved early in the penguin lineage. Analyses of fossilized color-imparting melanosomes reveal that their dimensions were similar to those of non-penguin avian taxa and that the feathering may have been predominantly gray and reddish-brown. In contrast, the dark black-brown color of extant penguin feathers is generated by large, ellipsoidal melanosomes previously unknown for birds. The nanostructure of penguin feathers was thus modified after earlier macrostructural modifications of feather shape linked to aquatic flight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clarke, Julia A -- Ksepka, Daniel T -- Salas-Gismondi, Rodolfo -- Altamirano, Ali J -- Shawkey, Matthew D -- D'Alba, Liliana -- Vinther, Jakob -- DeVries, Thomas J -- Baby, Patrice -- New York, N.Y. -- Science. 2010 Nov 12;330(6006):954-7. doi: 10.1126/science.1193604.

    Description: The Ediacaran Period (635 to 542 million years ago) was a time of fundamental environmental and evolutionary change, culminating in the first appearance of macroscopic animals. Here, we present a detailed spatial and temporal record of Ediacaran ocean chemistry for the Doushantuo Formation in the Nanhua Basin, South China. We find evidence for a metastable zone of euxinic (anoxic and sulfidic) waters impinging on the continental shelf and sandwiched within ferruginous [Fe(II)-enriched] deep waters. A stratified ocean with coeval oxic, sulfidic, and ferruginous zones, favored by overall low oceanic sulfate concentrations, was maintained dynamically throughout the Ediacaran Period. Our model reconciles seemingly conflicting geochemical redox conditions proposed previously for Ediacaran deep oceans and helps to explain the patchy temporal record of early metazoan fossils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Chao -- Love, Gordon D -- Lyons, Timothy W -- Fike, David A -- Sessions, Alex L -- Chu, Xuelei -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):80-3. doi: 10.1126/science.1182369.

    Description: White and colleagues (Research Articles, 2 October 2009, pp. 64-106 and www.sciencemag.org/ardipithecus) reported Ardipithecus ramidus as an exclusive member of the human lineage post-African ape divergence. However, their analysis of shared-derived characters provides insufficient evidence of an ancestor-descendant relationship and exclusivity to the hominid lineage. Molecular and anatomical studies rather suggest that Ar. ramidus predates the human/African ape divergence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sarmiento, Esteban E -- New York, N.Y. -- Science. 2010 May 28;328(5982):1105; author reply 1105. doi: 10.1126/science.1184148.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Foundation, East Brunswick, NJ 08816, USA. este444@yahoo.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20508113" target="_blank"〉PubMed〈/a〉

    Description: Hybrids between species are often sterile or inviable because the long-diverged genomes of their parents cause developmental problems when they come together in a single individual. According to the Dobzhansky-Muller (DM) model, the number of genes involved in these "intrinsic postzygotic incompatibilities" should increase faster than linearly with the divergence time between species. This straightforward prediction of the DM model has remained contentious owing to a lack of explicit tests. Examining two pairs of Drosophila species, we show that the number of genes involved in postzygotic isolation increases at least as fast as the square of the number of substitutions (an index of divergence time) between species. This observation verifies a key prediction of the DM model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matute, Daniel R -- Butler, Ian A -- Turissini, David A -- Coyne, Jerry A -- R01GM058260/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1518-21. doi: 10.1126/science.1193440.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, The University of Chicago, 1101 East 57th Street, Chicago, IL 60637, USA. dmatute@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847270" target="_blank"〉PubMed〈/a〉

    Description: Large-scale biodiversity gradients among environments and habitats are usually attributed to a complex array of ecological and evolutionary factors. We tested the evolutionary component of such gradients by compiling the environments of the geologically oldest occurrences of marine genera and using sampling standardization to assess if originations tended to be clustered in particular environments. Shallow, tropical environments and carbonate substrates all tend to have harbored high origination rates. Diversity within these environments tended to be preferentially generated in reefs, probably because of their habitat complexity. Reefs were also prolific at exporting diversity to other environments, which might be a consequence of low-diversity habitats being more susceptible to invasions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kiessling, Wolfgang -- Simpson, Carl -- Foote, Michael -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):196-8. doi: 10.1126/science.1182241.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum fur Naturkunde, Leibniz Institute for Research on Evolution and Biodiversity at the Humboldt University Berlin, 10115 Berlin, Germany. wolfgang.kiessling@mfn-berlin.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056888" target="_blank"〉PubMed〈/a〉

    Description: The extinction of dinosaurs at the Cretaceous/Paleogene (K/Pg) boundary was the seminal event that opened the door for the subsequent diversification of terrestrial mammals. Our compilation of maximum body size at the ordinal level by sub-epoch shows a near-exponential increase after the K/Pg. On each continent, the maximum size of mammals leveled off after 40 million years ago and thereafter remained approximately constant. There was remarkable congruence in the rate, trajectory, and upper limit across continents, orders, and trophic guilds, despite differences in geological and climatic history, turnover of lineages, and ecological variation. Our analysis suggests that although the primary driver for the evolution of giant mammals was diversification to fill ecological niches, environmental temperature and land area may have ultimately constrained the maximum size achieved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Felisa A -- Boyer, Alison G -- Brown, James H -- Costa, Daniel P -- Dayan, Tamar -- Ernest, S K Morgan -- Evans, Alistair R -- Fortelius, Mikael -- Gittleman, John L -- Hamilton, Marcus J -- Harding, Larisa E -- Lintulaakso, Kari -- Lyons, S Kathleen -- McCain, Christy -- Okie, Jordan G -- Saarinen, Juha J -- Sibly, Richard M -- Stephens, Patrick R -- Theodor, Jessica -- Uhen, Mark D -- New York, N.Y. -- Science. 2010 Nov 26;330(6008):1216-9. doi: 10.1126/science.1194830.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, MSC03 2020, University of New Mexico, Albuquerque, NM 87131, USA. fasmith@unm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21109666" target="_blank"〉PubMed〈/a〉

    Description: We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are important regulators of arthropod populations, including major agricultural pests and disease vectors, and Nasonia is an emerging genetic model, particularly for evolutionary and developmental genetics. Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation. Newly developed genome resources advance Nasonia for genetic research, accelerate mapping and cloning of quantitative trait loci, and will ultimately provide tools and knowledge for further increasing the utility of parasitoids as pest insect-control agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849982/" 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/PMC2849982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werren, John H -- Richards, Stephen -- Desjardins, Christopher A -- Niehuis, Oliver -- Gadau, Jurgen -- Colbourne, John K -- Nasonia Genome Working Group -- Beukeboom, Leo W -- Desplan, Claude -- Elsik, Christine G -- Grimmelikhuijzen, Cornelis J P -- Kitts, Paul -- Lynch, Jeremy A -- Murphy, Terence -- Oliveira, Deodoro C S G -- Smith, Christopher D -- van de Zande, Louis -- Worley, Kim C -- Zdobnov, Evgeny M -- Aerts, Maarten -- Albert, Stefan -- Anaya, Victor H -- Anzola, Juan M -- Barchuk, Angel R -- Behura, Susanta K -- Bera, Agata N -- Berenbaum, May R -- Bertossa, Rinaldo C -- Bitondi, Marcia M G -- Bordenstein, Seth R -- Bork, Peer -- Bornberg-Bauer, Erich -- Brunain, Marleen -- Cazzamali, Giuseppe -- Chaboub, Lesley -- Chacko, Joseph -- Chavez, Dean -- Childers, Christopher P -- Choi, Jeong-Hyeon -- Clark, Michael E -- Claudianos, Charles -- Clinton, Rochelle A -- Cree, Andrew G -- Cristino, Alexandre S -- Dang, Phat M -- Darby, Alistair C -- de Graaf, Dirk C -- Devreese, Bart -- Dinh, Huyen H -- Edwards, Rachel -- Elango, Navin -- Elhaik, Eran -- Ermolaeva, Olga -- Evans, Jay D -- Foret, Sylvain -- Fowler, Gerald R -- Gerlach, Daniel -- Gibson, Joshua D -- Gilbert, Donald G -- Graur, Dan -- Grunder, Stefan -- Hagen, Darren E -- Han, Yi -- Hauser, Frank -- Hultmark, Da -- Hunter, Henry C 4th -- Hurst, Gregory D D -- Jhangian, Shalini N -- Jiang, Huaiyang -- Johnson, Reed M -- Jones, Andrew K -- Junier, Thomas -- Kadowaki, Tatsuhiko -- Kamping, Albert -- Kapustin, Yuri -- Kechavarzi, Bobak -- Kim, Jaebum -- Kim, Jay -- Kiryutin, Boris -- Koevoets, Tosca -- Kovar, Christie L -- Kriventseva, Evgenia V -- Kucharski, Robert -- Lee, Heewook -- Lee, Sandra L -- Lees, Kristin -- Lewis, Lora R -- Loehlin, David W -- Logsdon, John M Jr -- Lopez, Jacqueline A -- Lozado, Ryan J -- Maglott, Donna -- Maleszka, Ryszard -- Mayampurath, Anoop -- Mazur, Danielle J -- McClure, Marcella A -- Moore, Andrew D -- Morgan, Margaret B -- Muller, Jean -- Munoz-Torres, Monica C -- Muzny, Donna M -- Nazareth, Lynne V -- Neupert, Susanne -- Nguyen, Ngoc B -- Nunes, Francis M F -- Oakeshott, John G -- Okwuonu, Geoffrey O -- Pannebakker, Bart A -- Pejaver, Vikas R -- Peng, Zuogang -- Pratt, Stephen C -- Predel, Reinhard -- Pu, Ling-Ling -- Ranson, Hilary -- Raychoudhury, Rhitoban -- Rechtsteiner, Andreas -- Reese, Justin T -- Reid, Jeffrey G -- Riddle, Megan -- Robertson, Hugh M -- Romero-Severson, Jeanne -- Rosenberg, Miriam -- Sackton, Timothy B -- Sattelle, David B -- Schluns, Helge -- Schmitt, Thomas -- Schneider, Martina -- Schuler, Andreas -- Schurko, Andrew M -- Shuker, David M -- Simoes, Zila L P -- Sinha, Saurabh -- Smith, Zachary -- Solovyev, Victor -- Souvorov, Alexandre -- Springauf, Andreas -- Stafflinger, Elisabeth -- Stage, Deborah E -- Stanke, Mario -- Tanaka, Yoshiaki -- Telschow, Arndt -- Trent, Carol -- Vattathil, Selina -- Verhulst, Eveline C -- Viljakainen, Lumi -- Wanner, Kevin W -- Waterhouse, Robert M -- Whitfield, James B -- Wilkes, Timothy E -- Williamson, Michael -- Willis, Judith H -- Wolschin, Florian -- Wyder, Stefan -- Yamada, Takuji -- Yi, Soojin V -- Zecher, Courtney N -- Zhang, Lan -- Gibbs, Richard A -- 5R01GM070026-04/GM/NIGMS NIH HHS/ -- 5R01HG000747-14/HG/NHGRI NIH HHS/ -- 5R24GM084917-02/GM/NIGMS NIH HHS/ -- AI028309-13A2/AI/NIAID NIH HHS/ -- R01 AI055624/AI/NIAID NIH HHS/ -- R01 GM064864/GM/NIGMS NIH HHS/ -- R01 GM064864-04/GM/NIGMS NIH HHS/ -- R01 GM064864-05A2/GM/NIGMS NIH HHS/ -- R01 GM070026/GM/NIGMS NIH HHS/ -- R01 GM070026-04S1/GM/NIGMS NIH HHS/ -- R01 GM079484/GM/NIGMS NIH HHS/ -- R01 GM085163/GM/NIGMS NIH HHS/ -- R01 GM085163-01/GM/NIGMS NIH HHS/ -- R01 GM085233/GM/NIGMS NIH HHS/ -- R01 HG000747/HG/NHGRI NIH HHS/ -- R01 HG000747-14/HG/NHGRI NIH HHS/ -- R01GM064864/GM/NIGMS NIH HHS/ -- R24 GM084917/GM/NIGMS NIH HHS/ -- R24 GM084917-01/GM/NIGMS NIH HHS/ -- R24 GM084917-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):343-8. doi: 10.1126/science.1178028.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075255" target="_blank"〉PubMed〈/a〉

    Description: Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture of animal genomes can be deeply modified and may therefore be largely nonadaptive. This rapidly evolving animal lineage thus offers unique perspectives on the level of genome plasticity. It also illuminates issues as fundamental as the mechanisms of intron gain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3760481/" 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/PMC3760481/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denoeud, France -- Henriet, Simon -- Mungpakdee, Sutada -- Aury, Jean-Marc -- Da Silva, Corinne -- Brinkmann, Henner -- Mikhaleva, Jana -- Olsen, Lisbeth Charlotte -- Jubin, Claire -- Canestro, Cristian -- Bouquet, Jean-Marie -- Danks, Gemma -- Poulain, Julie -- Campsteijn, Coen -- Adamski, Marcin -- Cross, Ismael -- Yadetie, Fekadu -- Muffato, Matthieu -- Louis, Alexandra -- Butcher, Stephen -- Tsagkogeorga, Georgia -- Konrad, Anke -- Singh, Sarabdeep -- Jensen, Marit Flo -- Huynh Cong, Evelyne -- Eikeseth-Otteraa, Helen -- Noel, Benjamin -- Anthouard, Veronique -- Porcel, Betina M -- Kachouri-Lafond, Rym -- Nishino, Atsuo -- Ugolini, Matteo -- Chourrout, Pascal -- Nishida, Hiroki -- Aasland, Rein -- Huzurbazar, Snehalata -- Westhof, Eric -- Delsuc, Frederic -- Lehrach, Hans -- Reinhardt, Richard -- Weissenbach, Jean -- Roy, Scott W -- Artiguenave, Francois -- Postlethwait, John H -- Manak, J Robert -- Thompson, Eric M -- Jaillon, Olivier -- Du Pasquier, Louis -- Boudinot, Pierre -- Liberles, David A -- Volff, Jean-Nicolas -- Philippe, Herve -- Lenhard, Boris -- Roest Crollius, Hugues -- Wincker, Patrick -- Chourrout, Daniel -- Z01 LM000073-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1381-5. doi: 10.1126/science.1194167.

    Description: Although microbes have been classically viewed as pathogens, it is now well established that the majority of host-bacterial interactions are symbiotic. During development and into adulthood, gut bacteria shape the tissues, cells, and molecular profile of our gastrointestinal immune system. This partnership, forged over many millennia of coevolution, is based on a molecular exchange involving bacterial signals that are recognized by host receptors to mediate beneficial outcomes for both microbes and humans. We explore how specific aspects of the adaptive immune system are influenced by intestinal commensal bacteria. Understanding the molecular mechanisms that mediate symbiosis between commensal bacteria and humans may redefine how we view the evolution of adaptive immunity and consequently how we approach the treatment of numerous immunologic disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3159383/" 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/PMC3159383/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Yun Kyung -- Mazmanian, Sarkis K -- AI088626/AI/NIAID NIH HHS/ -- DK078938/DK/NIDDK NIH HHS/ -- DK083633/DK/NIDDK NIH HHS/ -- R01 DK078938/DK/NIDDK NIH HHS/ -- R01 DK078938-01A2/DK/NIDDK NIH HHS/ -- R01 DK078938-02/DK/NIDDK NIH HHS/ -- R01 DK078938-03/DK/NIDDK NIH HHS/ -- R01 DK078938-04/DK/NIDDK NIH HHS/ -- R21 AI088626/AI/NIAID NIH HHS/ -- R21 AI088626-01/AI/NIAID NIH HHS/ -- R21 AI088626-02/AI/NIAID NIH HHS/ -- R21 DK083633/DK/NIDDK NIH HHS/ -- R21 DK083633-01A1/DK/NIDDK NIH HHS/ -- R21 DK083633-02/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1768-73. doi: 10.1126/science.1195568.〈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/21205662" target="_blank"〉PubMed〈/a〉

    Description: Tan et al. (Reports, 25 September 2009, p. 1686) argued that loss of tyrosine residues from proteins in metazoans was driven by positive selection to remove potentially deleterious phosphorylation sites. We challenge this hypothesis, providing evidence that the high guanine-cytosine (GC) content of metazoan genomes was the primary driver in the loss of tyrosine residues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, Zhixi -- Huang, Wei -- Gu, Xun -- New York, N.Y. -- Science. 2011 May 20;332(6032):917; author reply 917. doi: 10.1126/science.1187374.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MOE Key Laboratory of Contemporary Anthropology and Center for Evolutionary Biology, School of Life Sciences, Institutes of Biomedical Sciences, Fudan University, Shanghai 200433, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21596977" target="_blank"〉PubMed〈/a〉

    Description: Epistasis has substantial impacts on evolution, in particular, the rate of adaptation. We generated combinations of beneficial mutations that arose in a lineage during rapid adaptation of a bacterium whose growth depended on a newly introduced metabolic pathway. The proportional selective benefit for three of the four loci consistently decreased when they were introduced onto more fit backgrounds. These three alleles all reduced morphological defects caused by expression of the foreign pathway. A simple theoretical model segregating the apparent contribution of individual alleles to benefits and costs effectively predicted the interactions between them. These results provide the first evidence that patterns of epistasis may differ for within- and between-gene interactions during adaptation and that diminishing returns epistasis contributes to the consistent observation of decelerating fitness gains during adaptation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3244271/" 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/PMC3244271/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chou, Hsin-Hung -- Chiu, Hsuan-Chao -- Delaney, Nigel F -- Segre, Daniel -- Marx, Christopher J -- R01 GM078209/GM/NIGMS NIH HHS/ -- R01 GM078209-05/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Jun 3;332(6034):1190-2. doi: 10.1126/science.1203799.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21636771" target="_blank"〉PubMed〈/a〉

    Description: The gain, loss, and modification of gene regulatory elements may underlie a substantial proportion of phenotypic changes on animal lineages. To investigate the gain of regulatory elements throughout vertebrate evolution, we identified genome-wide sets of putative regulatory regions for five vertebrates, including humans. These putative regulatory regions are conserved nonexonic elements (CNEEs), which are evolutionarily conserved yet do not overlap any coding or noncoding mature transcript. We then inferred the branch on which each CNEE came under selective constraint. Our analysis identified three extended periods in the evolution of gene regulatory elements. Early vertebrate evolution was characterized by regulatory gains near transcription factors and developmental genes, but this trend was replaced by innovations near extracellular signaling genes, and then innovations near posttranslational protein modifiers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511857/" 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/PMC3511857/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowe, Craig B -- Kellis, Manolis -- Siepel, Adam -- Raney, Brian J -- Clamp, Michele -- Salama, Sofie R -- Kingsley, David M -- Lindblad-Toh, Kerstin -- Haussler, David -- 1U01-HG004695/HG/NHGRI NIH HHS/ -- 5P41-HG002371/HG/NHGRI NIH HHS/ -- P41 HG002371/HG/NHGRI NIH HHS/ -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50-HG02568/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01-HG004037/HG/NHGRI NIH HHS/ -- U01 HG004695/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54-HG003067/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Aug 19;333(6045):1019-24. doi: 10.1126/science.1202702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Biomolecular Science and Engineering, University of California, Santa Cruz, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21852499" target="_blank"〉PubMed〈/a〉

    Description: Diet changes are considered key events in human evolution. Most studies of early hominin diets focused on tooth size, shape, and craniomandibular morphology, as well as stone tools and butchered animal bones. However, in recent years, dental microwear and stable isotope analyses have hinted at unexpected diversity and complexity in early hominin diets. Some traditional ideas have held; others, such as an increasing reliance on hard-object feeding and a dichotomy between Australopithecus and Paranthropus, have been challenged. The first known evidence of C(4) plant (tropical grasses and sedges) and hard-object (e.g., seeds and nuts) consumption dates to millions of years after the appearance of the earliest probable hominins, and there are no consistent trends in diet change among these species through time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ungar, Peter S -- Sponheimer, Matt -- New York, N.Y. -- Science. 2011 Oct 14;334(6053):190-3. doi: 10.1126/science.1207701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Arkansas, Fayetteville, AR 72701, USA. pungar@uark.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21998380" target="_blank"〉PubMed〈/a〉

    Description: The advent of wood (secondary xylem) is a major event of the Paleozoic Era, facilitating the evolution of large perennial plants. The first steps of wood evolution are unknown. We describe two small Early Devonian (407 to 397 million years ago) plants with secondary xylem including simple rays. Their wood currently represents the earliest evidence of secondary growth in plants. The small size of the plants and the presence of thick-walled cortical cells confirm that wood early evolution was driven by hydraulic constraints rather than by the necessity of mechanical support for increasing height. The plants described here are most probably precursors of lignophytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gerrienne, Philippe -- Gensel, Patricia G -- Strullu-Derrien, Christine -- Lardeux, Hubert -- Steemans, Philippe -- Prestianni, Cyrille -- New York, N.Y. -- Science. 2011 Aug 12;333(6044):837. doi: 10.1126/science.1208882.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departement de Geologie, Universite de Liege (U.Lg), B18 Sart Tilman, B-4000 Liege 1, Belgium.

    Description: How synthetic can "synthetic biology" be? A literal interpretation of the name of this new life science discipline invokes expectations of the systematic construction of biological systems with cells being built module by module--from the bottom up. But can this possibly be achieved, taking into account the enormous complexity and redundancy of living systems, which distinguish them quite remarkably from design features that characterize human inventions? There are several recent developments in biology, in tight conjunction with quantitative disciplines, that may bring this literal perspective into the realm of the possible. However, such bottom-up engineering requires tools that were originally designed by nature's greatest tinkerer: evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwille, Petra -- New York, N.Y. -- Science. 2011 Sep 2;333(6047):1252-4. doi: 10.1126/science.1211701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics/BIOTEC, Technische Universitat (TU) Dresden, Tatzberg 47-51, D-01307 Dresden, Germany. schwille@biotec.tu-dresden.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21885774" target="_blank"〉PubMed〈/a〉

    Description: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" 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/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

    Description: Polyploidy, the doubling of genomic content, is a widespread feature, especially among plants, yet its macroevolutionary impacts are contentious. Traditionally, polyploidy has been considered an evolutionary dead end, whereas recent genomic studies suggest that polyploidy has been a key driver of macroevolutionary success. We examined the consequences of polyploidy on the time scale of genera across a diverse set of vascular plants, encompassing hundreds of inferred polyploidization events. Likelihood-based analyses indicate that polyploids generally exhibit lower speciation rates and higher extinction rates than diploids, providing the first quantitative corroboration of the dead-end hypothesis. The increased speciation rates of diploids can, in part, be ascribed to their capacity to speciate via polyploidy. Only particularly fit lineages of polyploids may persist to enjoy longer-term evolutionary success.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayrose, Itay -- Zhan, Shing H -- Rothfels, Carl J -- Magnuson-Ford, Karen -- Barker, Michael S -- Rieseberg, Loren H -- Otto, Sarah P -- New York, N.Y. -- Science. 2011 Sep 2;333(6047):1257. doi: 10.1126/science.1207205.

    Description: Epistatic interactions between mutations play a prominent role in evolutionary theories. Many studies have found that epistasis is widespread, but they have rarely considered beneficial mutations. We analyzed the effects of epistasis on fitness for the first five mutations to fix in an experimental population of Escherichia coli. Epistasis depended on the effects of the combined mutations--the larger the expected benefit, the more negative the epistatic effect. Epistasis thus tended to produce diminishing returns with genotype fitness, although interactions involving one particular mutation had the opposite effect. These data support models in which negative epistasis contributes to declining rates of adaptation over time. Sign epistasis was rare in this genome-wide study, in contrast to its prevalence in an earlier study of mutations in a single gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khan, Aisha I -- Dinh, Duy M -- Schneider, Dominique -- Lenski, Richard E -- Cooper, Tim F -- New York, N.Y. -- Science. 2011 Jun 3;332(6034):1193-6. doi: 10.1126/science.1203801.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Biochemistry, University of Houston, Houston, TX 77204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21636772" target="_blank"〉PubMed〈/a〉

    Description: The fossil record of early feathers has relied on carbonized compressions that lack fine structural detail. Specimens in amber are preserved in greater detail, but they are rare. Late Cretaceous coal-rich strata from western Canada provide the richest and most diverse Mesozoic feather assemblage yet reported from amber. The fossils include primitive structures closely matching the protofeathers of nonavian dinosaurs, offering new insights into their structure and function. Additional derived morphologies confirm that plumage specialized for flight and underwater diving had evolved in Late Cretaceous birds. Because amber preserves feather structure and pigmentation in unmatched detail, these fossils provide novel insights regarding feather evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McKellar, Ryan C -- Chatterton, Brian D E -- Wolfe, Alexander P -- Currie, Philip J -- New York, N.Y. -- Science. 2011 Sep 16;333(6049):1619-22. doi: 10.1126/science.1203344.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Atmospheric Sciences, University of Alberta, Edmonton, Alberta T6G 2E3, Canada. rcm1@ualberta.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21921196" target="_blank"〉PubMed〈/a〉

    Description: Hand bones from a single individual with a clear taxonomic affiliation are scarce in the hominin fossil record, which has hampered understanding the evolution of manipulative abilities in hominins. Here we describe and analyze a nearly complete wrist and hand of an adult female [Malapa Hominin 2 (MH2)] Australopithecus sediba from Malapa, South Africa (1.977 million years ago). The hand presents a suite of Australopithecus-like features, such as a strong flexor apparatus associated with arboreal locomotion, and Homo-like features, such as a long thumb and short fingers associated with precision gripping and possibly stone tool production. Comparisons to other fossil hominins suggest that there were at least two distinct hand morphotypes around the Plio-Pleistocene transition. The MH2 fossils suggest that Au. sediba may represent a basal condition associated with early stone tool use and production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kivell, Tracy L -- Kibii, Job M -- Churchill, Steven E -- Schmid, Peter -- Berger, Lee R -- New York, N.Y. -- Science. 2011 Sep 9;333(6048):1411-7. doi: 10.1126/science.1202625.

    Description: The conceptual ability to source, combine, and store substances that enhance technology or social practices represents a benchmark in the evolution of complex human cognition. Excavations in 2008 at Blombos Cave, South Africa, revealed a processing workshop where a liquefied ochre-rich mixture was produced and stored in two Haliotis midae (abalone) shells 100,000 years ago. Ochre, bone, charcoal, grindstones, and hammerstones form a composite part of this production toolkit. The application of the mixture is unknown, but possibilities include decoration and skin protection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henshilwood, Christopher S -- d'Errico, Francesco -- van Niekerk, Karen L -- Coquinot, Yvan -- Jacobs, Zenobia -- Lauritzen, Stein-Erik -- Menu, Michel -- Garcia-Moreno, Renata -- 249587/European Research Council/International -- New York, N.Y. -- Science. 2011 Oct 14;334(6053):219-22. doi: 10.1126/science.1211535.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Archaeology, History, Culture and Religion, University of Bergen, Bergen, Norway. christopher.henshilwood@ahkr.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21998386" target="_blank"〉PubMed〈/a〉
