Description: Animals across various phyla exhibit odor-evoked innate attraction behavior that is developmentally programmed. The mechanism underlying such behavior remains unclear because the odorants that elicit robust attraction responses and the neuronal circuits that mediate this behavior have not been identified. Here, we describe a functionally segregated population of olfactory sensory...

Description: Decarbonization of electricity generation can support climate-change mitigation and presents an opportunity to address pollution resulting from fossil-fuel combustion. Generally, renewable technologies require higher initial investments in infrastructure than fossil-based power systems. To assess the tradeoffs of increased up-front emissions and reduced operational emissions, we present, to our knowledge, the...

Description: To provide context for the diversification of archosaurs--the group that includes crocodilians, dinosaurs, and birds--we generated draft genomes of three crocodilians: Alligator mississippiensis (the American alligator), Crocodylus porosus (the saltwater crocodile), and Gavialis gangeticus (the Indian gharial). We observed an exceptionally slow rate of genome evolution within crocodilians at all levels, including nucleotide substitutions, indels, transposable element content and movement, gene family evolution, and chromosomal synteny. When placed within the context of related taxa including birds and turtles, this suggests that the common ancestor of all of these taxa also exhibited slow genome evolution and that the comparatively rapid evolution is derived in birds. The data also provided the opportunity to analyze heterozygosity in crocodilians, which indicates a likely reduction in population size for all three taxa through the Pleistocene. Finally, these data combined with newly published bird genomes allowed us to reconstruct the partial genome of the common ancestor of archosaurs, thereby providing a tool to investigate the genetic starting material of crocodilians, birds, and dinosaurs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4386873/" 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/PMC4386873/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Richard E -- Braun, Edward L -- Armstrong, Joel -- Earl, Dent -- Nguyen, Ngan -- Hickey, Glenn -- Vandewege, Michael W -- St John, John A -- Capella-Gutierrez, Salvador -- Castoe, Todd A -- Kern, Colin -- Fujita, Matthew K -- Opazo, Juan C -- Jurka, Jerzy -- Kojima, Kenji K -- Caballero, Juan -- Hubley, Robert M -- Smit, Arian F -- Platt, Roy N -- Lavoie, Christine A -- Ramakodi, Meganathan P -- Finger, John W Jr -- Suh, Alexander -- Isberg, Sally R -- Miles, Lee -- Chong, Amanda Y -- Jaratlerdsiri, Weerachai -- Gongora, Jaime -- Moran, Christopher -- Iriarte, Andres -- McCormack, John -- Burgess, Shane C -- Edwards, Scott V -- Lyons, Eric -- Williams, Christina -- Breen, Matthew -- Howard, Jason T -- Gresham, Cathy R -- Peterson, Daniel G -- Schmitz, Jurgen -- Pollock, David D -- Haussler, David -- Triplett, Eric W -- Zhang, Guojie -- Irie, Naoki -- Jarvis, Erich D -- Brochu, Christopher A -- Schmidt, Carl J -- McCarthy, Fiona M -- Faircloth, Brant C -- Hoffmann, Federico G -- Glenn, Travis C -- Gabaldon, Toni -- Paten, Benedict -- Ray, David A -- 1U41HG006992-2/HG/NHGRI NIH HHS/ -- 1U41HG007234-01/HG/NHGRI NIH HHS/ -- 5U01HG004695/HG/NHGRI NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- U41 HG006992/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1254449. doi: 10.1126/science.1254449.

Description: To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves using phylogenomic methods created to handle genome-scale data. We recovered a highly resolved tree that confirms previously controversial sister or close relationships. We identified the first divergence in Neoaves, two groups we named Passerea and Columbea, representing independent lineages of diverse and convergently evolved land and water bird species. Among Passerea, we infer the common ancestor of core landbirds to have been an apex predator and confirm independent gains of vocal learning. Among Columbea, we identify pigeons and flamingoes as belonging to sister clades. Even with whole genomes, some of the earliest branches in Neoaves proved challenging to resolve, which was best explained by massive protein-coding sequence convergence and high levels of incomplete lineage sorting that occurred during a rapid radiation after the Cretaceous-Paleogene mass extinction event about 66 million years ago.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4405904/" 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/PMC4405904/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jarvis, Erich D -- Mirarab, Siavash -- Aberer, Andre J -- Li, Bo -- Houde, Peter -- Li, Cai -- Ho, Simon Y W -- Faircloth, Brant C -- Nabholz, Benoit -- Howard, Jason T -- Suh, Alexander -- Weber, Claudia C -- da Fonseca, Rute R -- Li, Jianwen -- Zhang, Fang -- Li, Hui -- Zhou, Long -- Narula, Nitish -- Liu, Liang -- Ganapathy, Ganesh -- Boussau, Bastien -- Bayzid, Md Shamsuzzoha -- Zavidovych, Volodymyr -- Subramanian, Sankar -- Gabaldon, Toni -- Capella-Gutierrez, Salvador -- Huerta-Cepas, Jaime -- Rekepalli, Bhanu -- Munch, Kasper -- Schierup, Mikkel -- Lindow, Bent -- Warren, Wesley C -- Ray, David -- Green, Richard E -- Bruford, Michael W -- Zhan, Xiangjiang -- Dixon, Andrew -- Li, Shengbin -- Li, Ning -- Huang, Yinhua -- Derryberry, Elizabeth P -- Bertelsen, Mads Frost -- Sheldon, Frederick H -- Brumfield, Robb T -- Mello, Claudio V -- Lovell, Peter V -- Wirthlin, Morgan -- Schneider, Maria Paula Cruz -- Prosdocimi, Francisco -- Samaniego, Jose Alfredo -- Vargas Velazquez, Amhed Missael -- Alfaro-Nunez, Alonzo -- Campos, Paula F -- Petersen, Bent -- Sicheritz-Ponten, Thomas -- Pas, An -- Bailey, Tom -- Scofield, Paul -- Bunce, Michael -- Lambert, David M -- Zhou, Qi -- Perelman, Polina -- Driskell, Amy C -- Shapiro, Beth -- Xiong, Zijun -- Zeng, Yongli -- Liu, Shiping -- Li, Zhenyu -- Liu, Binghang -- Wu, Kui -- Xiao, Jin -- Yinqi, Xiong -- Zheng, Qiuemei -- Zhang, Yong -- Yang, Huanming -- Wang, Jian -- Smeds, Linnea -- Rheindt, Frank E -- Braun, Michael -- Fjeldsa, Jon -- Orlando, Ludovic -- Barker, F Keith -- Jonsson, Knud Andreas -- Johnson, Warren -- Koepfli, Klaus-Peter -- O'Brien, Stephen -- Haussler, David -- Ryder, Oliver A -- Rahbek, Carsten -- Willerslev, Eske -- Graves, Gary R -- Glenn, Travis C -- McCormack, John -- Burt, Dave -- Ellegren, Hans -- Alstrom, Per -- Edwards, Scott V -- Stamatakis, Alexandros -- Mindell, David P -- Cracraft, Joel -- Braun, Edward L -- Warnow, Tandy -- Jun, Wang -- Gilbert, M Thomas P -- Zhang, Guojie -- DP1 OD000448/OD/NIH HHS/ -- DP1OD000448/OD/NIH HHS/ -- R24 GM092842/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1320-31. doi: 10.1126/science.1253451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Howard Hughes Medical Institute (HHMI), and Duke University Medical Center, Durham, NC 27710, USA. jarvis@neuro.duke.edu tandywarnow@gmail.com mtpgilbert@gmail.com wangj@genomics.cn zhanggj@genomics.cn. ; Department of Computer Science, The University of Texas at Austin, Austin, TX 78712, USA. ; Scientific Computing Group, Heidelberg Institute for Theoretical Studies, Heidelberg, Germany. ; China National GeneBank, BGI-Shenzhen, Shenzhen 518083, China.

Description: Identification of retrotransposon insertions in nonmodel taxa can be technically challenging and costly. This has inhibited progress in understanding retrotransposon insertion dynamics outside of a few well-studied species. To address this problem, we have extended a retrotransposon-based capture and sequence method (ME-Scan [mobile element scanning]) to identify insertions belonging to the Ves family of short interspersed elements (SINEs) across seven species of the bat genus Myotis. We identified between 120,000 and 143,000 SINE insertions in six taxa lacking a draft genome by comparing to the M. lucifugus reference genome. On average, each Ves insertion was sequenced to 129.6 x coverage. When mapped back to the M. lucifugus reference genome, all insertions were confidently assigned within a 10-bp window. Polymorphic Ves insertions were identified in each taxon based on their mapped locations. Using cross-species comparisons and the identified insertion positions, a presence–absence matrix was created for approximately 796,000 insertions. Dollo parsimony analysis of more than 85,000 phylogenetically informative insertions recovered strongly supported, monophyletic clades that correspond with the biogeography of each taxa. This phylogeny is similar to previously published mitochondrial phylogenies, with the exception of the placement of M. vivesi. These results support the utility of our variation on ME-Scan to identify polymorphic retrotransposon insertions in taxa without a reference genome and for large-scale retrotransposon-based phylogenetics.

Description: Chicken repeat 1 (CR1) retroposons are long interspersed elements (LINEs) that are ubiquitous within amniote genomes and constitute the most abundant family of transposed elements in birds, crocodilians, turtles, and snakes. They are also present in mammalian genomes, where they reside as numerous relics of ancient retroposition events. Yet, despite their relevance for understanding amniote genome evolution, the diversity and evolution of CR1 elements has never been studied on an amniote-wide level. We reconstruct the temporal and quantitative activity of CR1 subfamilies via presence/absence analyses across crocodilian phylogeny and comparative analyses of 12 crocodilian genomes, revealing relative genomic stasis of retroposition during genome evolution of extant Crocodylia. Our large-scale phylogenetic analysis of amniote CR1 subfamilies suggests the presence of at least seven ancient CR1 lineages in the amniote ancestor; and amniote-wide analyses of CR1 successions and quantities reveal differential retention (presence of ancient relics or recent activity) of these CR1 lineages across amniote genome evolution. Interestingly, birds and lepidosaurs retained the fewest ancient CR1 lineages among amniotes and also exhibit smaller genome sizes. Our study is the first to analyze CR1 evolution in a genome-wide and amniote-wide context and the data strongly suggest that the ancestral amniote genome contained myriad CR1 elements from multiple ancient lineages, and remnants of these are still detectable in the relatively stable genomes of crocodilians and turtles. Early mammalian genome evolution was thus characterized by a drastic shift from CR1 prevalence to dominance and hyperactivity of L2 LINEs in monotremes and L1 LINEs in therians.

Schwab Electromagnetic resonators can be used to probe the quantum properties of mechanical objects. Scientists show that an imbalance between phonon absorption and emission—a distinct quantum signature—can be traced back to quantum fluctuations of either mechanical or microwave fields, depending on the measurement details.

Description: The domestic rock pigeon ( Columba livia ) is among the most widely distributed and phenotypically diverse avian species. C. livia is broadly studied in ecology, genetics, physiology, behavior, and evolutionary biology, and has recently emerged as a model for understanding the molecular basis of anatomical diversity, the magnetic sense, and other key aspects of avian biology. Here we report an update to the C. livia genome reference assembly and gene annotation dataset. Greatly increased scaffold lengths in the updated reference assembly, along with an updated annotation set, provide improved tools for evolutionary and functional genetic studies of the pigeon, and for comparative avian genomics in general.
