Description: Evolutionary changes in traits involved in both ecological divergence and mate choice may produce reproductive isolation and speciation. However, there are few examples of such dual traits, and the genetic and molecular bases of their evolution have not been identified. We show that methyl-branched cuticular hydrocarbons (mbCHCs) are a dual trait that affects both desiccation resistance and mate choice in Drosophila serrata. We identify a fatty acid synthase mFAS (CG3524) responsible for mbCHC production in Drosophila and find that expression of mFAS is undetectable in oenocytes (cells that produce CHCs) of a closely related, desiccation-sensitive species, D. birchii, due in part to multiple changes in cis-regulatory sequences of mFAS. We suggest that ecologically influenced changes in the production of mbCHCs have contributed to reproductive isolation between the two species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, Henry -- Loehlin, David W -- Dufour, Heloise D -- Vaccarro, Kathy -- Millar, Jocelyn G -- Carroll, Sean B -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1148-51. doi: 10.1126/science.1249998.

Description: In its largest outbreak, Ebola virus disease is spreading through Guinea, Liberia, Sierra Leone, and Nigeria. We sequenced 99 Ebola virus genomes from 78 patients in Sierra Leone to ~2000x coverage. We observed a rapid accumulation of interhost and intrahost genetic variation, allowing us to characterize patterns of viral transmission over the initial weeks of the epidemic. This West African variant likely diverged from central African lineages around 2004, crossed from Guinea to Sierra Leone in May 2014, and has exhibited sustained human-to-human transmission subsequently, with no evidence of additional zoonotic sources. Because many of the mutations alter protein sequences and other biologically meaningful targets, they should be monitored for impact on diagnostics, vaccines, and therapies critical to outbreak response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431643/" 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/PMC4431643/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gire, Stephen K -- Goba, Augustine -- Andersen, Kristian G -- Sealfon, Rachel S G -- Park, Daniel J -- Kanneh, Lansana -- Jalloh, Simbirie -- Momoh, Mambu -- Fullah, Mohamed -- Dudas, Gytis -- Wohl, Shirlee -- Moses, Lina M -- Yozwiak, Nathan L -- Winnicki, Sarah -- Matranga, Christian B -- Malboeuf, Christine M -- Qu, James -- Gladden, Adrianne D -- Schaffner, Stephen F -- Yang, Xiao -- Jiang, Pan-Pan -- Nekoui, Mahan -- Colubri, Andres -- Coomber, Moinya Ruth -- Fonnie, Mbalu -- Moigboi, Alex -- Gbakie, Michael -- Kamara, Fatima K -- Tucker, Veronica -- Konuwa, Edwin -- Saffa, Sidiki -- Sellu, Josephine -- Jalloh, Abdul Azziz -- Kovoma, Alice -- Koninga, James -- Mustapha, Ibrahim -- Kargbo, Kandeh -- Foday, Momoh -- Yillah, Mohamed -- Kanneh, Franklyn -- Robert, Willie -- Massally, James L B -- Chapman, Sinead B -- Bochicchio, James -- Murphy, Cheryl -- Nusbaum, Chad -- Young, Sarah -- Birren, Bruce W -- Grant, Donald S -- Scheiffelin, John S -- Lander, Eric S -- Happi, Christian -- Gevao, Sahr M -- Gnirke, Andreas -- Rambaut, Andrew -- Garry, Robert F -- Khan, S Humarr -- Sabeti, Pardis C -- 095831/Wellcome Trust/United Kingdom -- 1DP2OD006514-01/OD/NIH HHS/ -- 1U01HG007480-01/HG/NHGRI NIH HHS/ -- 260864/European Research Council/International -- DP2 OD006514/OD/NIH HHS/ -- GM080177/GM/NIGMS NIH HHS/ -- HHSN272200900049C/AI/NIAID NIH HHS/ -- HHSN272200900049C/PHS HHS/ -- T32 GM080177/GM/NIGMS NIH HHS/ -- U01 HG007480/HG/NHGRI NIH HHS/ -- U19 AI110818/AI/NIAID NIH HHS/ -- U19 AI115589/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1369-72. doi: 10.1126/science.1259657.

Description: The human neocortex has numerous specialized functional areas whose formation is poorly understood. Here, we describe a 15-base pair deletion mutation in a regulatory element of GPR56 that selectively disrupts human cortex surrounding the Sylvian fissure bilaterally including "Broca's area," the primary language area, by disrupting regional GPR56 expression and blocking RFX transcription factor binding. GPR56 encodes a heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptor required for normal cortical development and is expressed in cortical progenitor cells. GPR56 expression levels regulate progenitor proliferation. GPR56 splice forms are highly variable between mice and humans, and the regulatory element of gyrencephalic mammals directs restricted lateral cortical expression. Our data reveal a mechanism by which control of GPR56 expression pattern by multiple alternative promoters can influence stem cell proliferation, gyral patterning, and, potentially, neocortex evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480613/" 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/PMC4480613/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bae, Byoung-Il -- Tietjen, Ian -- Atabay, Kutay D -- Evrony, Gilad D -- Johnson, Matthew B -- Asare, Ebenezer -- Wang, Peter P -- Murayama, Ayako Y -- Im, Kiho -- Lisgo, Steven N -- Overman, Lynne -- Sestan, Nenad -- Chang, Bernard S -- Barkovich, A James -- Grant, P Ellen -- Topcu, Meral -- Politsky, Jeffrey -- Okano, Hideyuki -- Piao, Xianhua -- Walsh, Christopher A -- 2R01NS035129/NS/NINDS NIH HHS/ -- G0700089/Medical Research Council/United Kingdom -- GR082557/Wellcome Trust/United Kingdom -- HHSN275200900011C/PHS HHS/ -- N01-HD-9-0011/HD/NICHD NIH HHS/ -- R01 NS035129/NS/NINDS NIH HHS/ -- U01 MH081896/MH/NIMH NIH HHS/ -- U01MH081896/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):764-8. doi: 10.1126/science.1244392.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics and Genomics, Manton Center for Orphan Disease, and Howard Hughes Medical Institute, Boston Children's Hospital, Broad Institute of MIT and Harvard, and Departments of Pediatrics and Neurology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24531968" target="_blank"〉PubMed〈/a〉

Description: Fucosylation of intestinal epithelial cells, catalyzed by fucosyltransferase 2 (Fut2), is a major glycosylation mechanism of host-microbiota symbiosis. Commensal bacteria induce epithelial fucosylation, and epithelial fucose is used as a dietary carbohydrate by many of these bacteria. However, the molecular and cellular mechanisms that regulate the induction of epithelial fucosylation are unknown. Here, we show that type 3 innate lymphoid cells (ILC3) induced intestinal epithelial Fut2 expression and fucosylation in mice. This induction required the cytokines interleukin-22 and lymphotoxin in a commensal bacteria-dependent and -independent manner, respectively. Disruption of intestinal fucosylation led to increased susceptibility to infection by Salmonella typhimurium. Our data reveal a role for ILC3 in shaping the gut microenvironment through the regulation of epithelial glycosylation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4774895/" 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/PMC4774895/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goto, Yoshiyuki -- Obata, Takashi -- Kunisawa, Jun -- Sato, Shintaro -- Ivanov, Ivaylo I -- Lamichhane, Aayam -- Takeyama, Natsumi -- Kamioka, Mariko -- Sakamoto, Mitsuo -- Matsuki, Takahiro -- Setoyama, Hiromi -- Imaoka, Akemi -- Uematsu, Satoshi -- Akira, Shizuo -- Domino, Steven E -- Kulig, Paulina -- Becher, Burkhard -- Renauld, Jean-Christophe -- Sasakawa, Chihiro -- Umesaki, Yoshinori -- Benno, Yoshimi -- Kiyono, Hiroshi -- 1R01DK098378/DK/NIDDK NIH HHS/ -- R01 DK098378/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1254009. doi: 10.1126/science.1254009.

Description: Ecological specialization should minimize niche overlap, yet herbivorous neotropical flies (Blepharoneura) and their lethal parasitic wasps (parasitoids) exhibit both extreme specialization and apparent niche overlap in host plants. From just two plant species at one site in Peru, we collected 3636 flowers yielding 1478 fly pupae representing 14 Blepharoneura fly species, 18 parasitoid species (14 Bellopius species), and parasitoid-host associations, all discovered through analysis of molecular data. Multiple sympatric species specialize on the same sex flowers of the same fly host-plant species-which suggests extreme niche overlap; however, niche partitioning was exposed by interactions between wasps and flies. Most Bellopius species emerged as adults from only one fly species, yet evidence from pupae (preadult emergence samples) show that most Bellopius also attacked additional fly species but never emerged as adults from those flies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condon, Marty A -- Scheffer, Sonja J -- Lewis, Matthew L -- Wharton, Robert -- Adams, Dean C -- Forbes, Andrew A -- New York, N.Y. -- Science. 2014 Mar 14;343(6176):1240-4. doi: 10.1126/science.1245007.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Cornell College, Mount Vernon, IA 52314, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24626926" target="_blank"〉PubMed〈/a〉

Description: The New World Arctic, the last region of the Americas to be populated by humans, has a relatively well-researched archaeology, but an understanding of its genetic history is lacking. We present genome-wide sequence data from ancient and present-day humans from Greenland, Arctic Canada, Alaska, Aleutian Islands, and Siberia. We show that Paleo-Eskimos (~3000 BCE to 1300 CE) represent a migration pulse into the Americas independent of both Native American and Inuit expansions. Furthermore, the genetic continuity characterizing the Paleo-Eskimo period was interrupted by the arrival of a new population, representing the ancestors of present-day Inuit, with evidence of past gene flow between these lineages. Despite periodic abandonment of major Arctic regions, a single Paleo-Eskimo metapopulation likely survived in near-isolation for more than 4000 years, only to vanish around 700 years ago.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raghavan, Maanasa -- DeGiorgio, Michael -- Albrechtsen, Anders -- Moltke, Ida -- Skoglund, Pontus -- Korneliussen, Thorfinn S -- Gronnow, Bjarne -- Appelt, Martin -- Gullov, Hans Christian -- Friesen, T Max -- Fitzhugh, William -- Malmstrom, Helena -- Rasmussen, Simon -- Olsen, Jesper -- Melchior, Linea -- Fuller, Benjamin T -- Fahrni, Simon M -- Stafford, Thomas Jr -- Grimes, Vaughan -- Renouf, M A Priscilla -- Cybulski, Jerome -- Lynnerup, Niels -- Lahr, Marta Mirazon -- Britton, Kate -- Knecht, Rick -- Arneborg, Jette -- Metspalu, Mait -- Cornejo, Omar E -- Malaspinas, Anna-Sapfo -- Wang, Yong -- Rasmussen, Morten -- Raghavan, Vibha -- Hansen, Thomas V O -- Khusnutdinova, Elza -- Pierre, Tracey -- Dneprovsky, Kirill -- Andreasen, Claus -- Lange, Hans -- Hayes, M Geoffrey -- Coltrain, Joan -- Spitsyn, Victor A -- Gotherstrom, Anders -- Orlando, Ludovic -- Kivisild, Toomas -- Villems, Richard -- Crawford, Michael H -- Nielsen, Finn C -- Dissing, Jorgen -- Heinemeier, Jan -- Meldgaard, Morten -- Bustamante, Carlos -- O'Rourke, Dennis H -- Jakobsson, Mattias -- Gilbert, M Thomas P -- Nielsen, Rasmus -- Willerslev, Eske -- New York, N.Y. -- Science. 2014 Aug 29;345(6200):1255832. doi: 10.1126/science.1255832.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for GeoGenetics, Natural History Museum of Denmark, University of Copenhagen, Oster Voldgade 5-7, 1350 Copenhagen, Denmark. ; Department of Biology, Pennsylvania State University, 502 Wartik Laboratory, University Park, PA 16802, USA. ; Bioinformatics Centre, Department of Biology, University of Copenhagen, Ole Maaloes Vej 5, 2200 Copenhagen, Denmark. ; Bioinformatics Centre, Department of Biology, University of Copenhagen, Ole Maaloes Vej 5, 2200 Copenhagen, Denmark.

Description: The ethanolamine utilization (eut) locus of Enterococcus faecalis, containing at least 19 genes distributed over four polycistronic messenger RNAs, appears to be regulated by a single adenosyl cobalamine (AdoCbl)-responsive riboswitch. We report that the AdoCbl-binding riboswitch is part of a small, trans-acting RNA, EutX, which additionally contains a dual-hairpin substrate for the RNA binding-response regulator, EutV. In the absence of AdoCbl, EutX uses this structure to sequester EutV. EutV is known to regulate the eut messenger RNAs by binding dual-hairpin structures that overlap terminators and thus prevent transcription termination. In the presence of AdoCbl, EutV cannot bind to EutX and, instead, causes transcriptional read through of multiple eut genes. This work introduces riboswitch-mediated control of protein sequestration as a posttranscriptional mechanism to coordinately regulate gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4356242/" 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/PMC4356242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DebRoy, Sruti -- Gebbie, Margo -- Ramesh, Arati -- Goodson, Jonathan R -- Cruz, Melissa R -- van Hoof, Ambro -- Winkler, Wade C -- Garsin, Danielle A -- P30 DK056338/DK/NIDDK NIH HHS/ -- R01 AI076406/AI/NIAID NIH HHS/ -- R01 AI110432/AI/NIAID NIH HHS/ -- R01 GM099790/GM/NIGMS NIH HHS/ -- R01AI076406/AI/NIAID NIH HHS/ -- R01GM099790/GM/NIGMS NIH HHS/ -- R56 AI110432/AI/NIAID NIH HHS/ -- R56AI110432/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 22;345(6199):937-40. doi: 10.1126/science.1255091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, The University of Texas Health Science Center at Houston, TX 77030, USA. ; Department of Cell Biology and Molecular Genetics, University of Maryland, College Park, MD 20742, USA. ; Department of Biochemistry, The University of Texas Southwestern Medical Center, Dallas, TX 75390, USA. ; Department of Cell Biology and Molecular Genetics, University of Maryland, College Park, MD 20742, USA. danielle.a.garsin@uth.tmc.edu wwinkler@umd.edu. ; Department of Microbiology and Molecular Genetics, The University of Texas Health Science Center at Houston, TX 77030, USA. danielle.a.garsin@uth.tmc.edu wwinkler@umd.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25146291" target="_blank"〉PubMed〈/a〉

Description: The genetic changes underlying the initial steps of animal domestication are still poorly understood. We generated a high-quality reference genome for the rabbit and compared it to resequencing data from populations of wild and domestic rabbits. We identified more than 100 selective sweeps specific to domestic rabbits but only a relatively small number of fixed (or nearly fixed) single-nucleotide polymorphisms (SNPs) for derived alleles. SNPs with marked allele frequency differences between wild and domestic rabbits were enriched for conserved noncoding sites. Enrichment analyses suggest that genes affecting brain and neuronal development have often been targeted during domestication. We propose that because of a truly complex genetic background, tame behavior in rabbits and other domestic animals evolved by shifts in allele frequencies at many loci, rather than by critical changes at only a few domestication loci.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carneiro, Miguel -- Rubin, Carl-Johan -- Di Palma, Federica -- Albert, Frank W -- Alfoldi, Jessica -- Barrio, Alvaro Martinez -- Pielberg, Gerli -- Rafati, Nima -- Sayyab, Shumaila -- Turner-Maier, Jason -- Younis, Shady -- Afonso, Sandra -- Aken, Bronwen -- Alves, Joel M -- Barrell, Daniel -- Bolet, Gerard -- Boucher, Samuel -- Burbano, Hernan A -- Campos, Rita -- Chang, Jean L -- Duranthon, Veronique -- Fontanesi, Luca -- Garreau, Herve -- Heiman, David -- Johnson, Jeremy -- Mage, Rose G -- Peng, Ze -- Queney, Guillaume -- Rogel-Gaillard, Claire -- Ruffier, Magali -- Searle, Steve -- Villafuerte, Rafael -- Xiong, Anqi -- Young, Sarah -- Forsberg-Nilsson, Karin -- Good, Jeffrey M -- Lander, Eric S -- Ferrand, Nuno -- Lindblad-Toh, Kerstin -- Andersson, Leif -- 095908/Wellcome Trust/United Kingdom -- U54 HG003067/HG/NHGRI NIH HHS/ -- WT095908/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 29;345(6200):1074-9. doi: 10.1126/science.1253714.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CIBIO/InBIO, Centro de Investigacao em Biodiversidade e Recursos Geneticos, Campus Agrario de Vairao, Universidade do Porto, 4485-661, Vairao, Portugal. ; Science for Life Laboratory Uppsala, Department of Medical Biochemistry and Microbiology, Uppsala University, Uppsala, Sweden. ; Broad Institute of Harvard and Massachusetts Institute of Technology, 7 Cambridge Center, Cambridge, MA 02142, USA.

Description: Cellular memory is crucial to many natural biological processes and sophisticated synthetic biology applications. Existing cellular memories rely on epigenetic switches or recombinases, which are limited in scalability and recording capacity. In this work, we use the DNA of living cell populations as genomic "tape recorders" for the analog and distributed recording of long-term event histories. We describe a platform for generating single-stranded DNA (ssDNA) in vivo in response to arbitrary transcriptional signals. When coexpressed with a recombinase, these intracellularly expressed ssDNAs target specific genomic DNA addresses, resulting in precise mutations that accumulate in cell populations as a function of the magnitude and duration of the inputs. This platform could enable long-term cellular recorders for environmental and biomedical applications, biological state machines, and enhanced genome engineering strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4266475/" 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/PMC4266475/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farzadfard, Fahim -- Lu, Timothy K -- 1DP2OD008435/OD/NIH HHS/ -- 1P50GM098792/GM/NIGMS NIH HHS/ -- DP2 OD008435/OD/NIH HHS/ -- P50 GM098792/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Nov 14;346(6211):1256272. doi: 10.1126/science.1256272.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Synthetic Biology Group, Research Laboratory of Electronics, Department of Electrical Engineering and Computer Science and Department of Biological Engineering, Massachusetts Institute of Technology (MIT), 77 Massachusetts Avenue, Cambridge, MA 02139, USA.

Description: Understanding the spatial organization of gene expression with single-nucleotide resolution requires localizing the sequences of expressed RNA transcripts within a cell in situ. Here, we describe fluorescent in situ RNA sequencing (FISSEQ), in which stably cross-linked complementary DNA (cDNA) amplicons are sequenced within a biological sample. Using 30-base reads from 8102 genes in situ, we examined RNA expression and localization in human primary fibroblasts with a simulated wound-healing assay. FISSEQ is compatible with tissue sections and whole-mount embryos and reduces the limitations of optical resolution and noisy signals on single-molecule detection. Our platform enables massively parallel detection of genetic elements, including gene transcripts and molecular barcodes, and can be used to investigate cellular phenotype, gene regulation, and environment in situ.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4140943/" 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/PMC4140943/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Je Hyuk -- Daugharthy, Evan R -- Scheiman, Jonathan -- Kalhor, Reza -- Yang, Joyce L -- Ferrante, Thomas C -- Terry, Richard -- Jeanty, Sauveur S F -- Li, Chao -- Amamoto, Ryoji -- Peters, Derek T -- Turczyk, Brian M -- Marblestone, Adam H -- Inverso, Samuel A -- Bernard, Amy -- Mali, Prashant -- Rios, Xavier -- Aach, John -- Church, George M -- GM080177/GM/NIGMS NIH HHS/ -- MH098977/MH/NIMH NIH HHS/ -- P50 HG005550/HG/NHGRI NIH HHS/ -- RC2 HL102815/HL/NHLBI NIH HHS/ -- RC2HL102815/HL/NHLBI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- T32 GM080177/GM/NIGMS NIH HHS/ -- U01 MH098977/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1360-3. doi: 10.1126/science.1250212.
