    Description: There has been a massive increase in recent years of the use of lead (Pb) isotopes in attempts to better understand sources and pathways of Pb in the environment and in man or experimental animals. Unfortunately, there have been many cases where the quality of the isotopic data, especially that obtained by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS), are questionable, resulting in questionable identification of potential sources, which, in turn, impacts study interpretation and conclusions. We present several cases where the isotopic data have compromised interpretation because of the use of only the major isotopes 208Pb/206Pb and 207Pb/206Pb, or their graphing in other combinations. We also present some examples comparing high precision data from thermal ionization (TIMS) or multi-collector plasma mass spectrometry (MC-ICP-MS) to illustrate the deficiency in the Q-ICP-MS data. In addition, we present cases where Pb isotopic ratios measured on Q-ICP-MS are virtually impossible for terrestrial samples. We also evaluate the Pb isotopic data for rat studies, which had concluded that Pb isotopic fractionation occurs between different organs and suggest that this notion of biological fractionation of Pb as an explanation for isotopic differences is not valid. Overall, the brief review of these case studies shows that Q-ICP-MS as commonly practiced is not a suitable technique for precise and accurate Pb isotopic analysis in the environment and health fields

    Description: A new study suggests that common settings used in software for analyzing brain scans may lead to false positive results. Researchers led by Anders Eklund, an electrical engineer at Linköping University in Sweden, analyzed functional magnetic resonance imaging (fMRI) data from several public databases. Certain software settings, the team found, could give rise to a false positive result up to 70% of the time. In the context of a typical fMRI experiment, that could lead researchers to wrongly conclude that activity in a certain area of the brain plays a role in a cognitive function such as perception or memory.

    Description: The vast majority of genes in sexually reproducing eukaryotes can recombine during the production of gametes. This reshuffling generates new genotypes that may provide selective advantages. However, reshuffling does not occur among the few genes in the genomes of cytoplasmic organelles (chloroplasts and mitochondria). Instead, these organelles are almost always transmitted through maternal inheritance (1). Why is this phenomenon widespread and how is it achieved? On page 394 of this issue, Zhou et al. (2) solve part of this puzzle by identifying the enzyme that degrades sperm mitochondrial DNA after fertilization. Author: Alexander M. van der Bliek

    Description: As you navigate a landscape, certain neurons in the brain fire at multiple locations, marking out a hexagonal grid on a mental map. The discovery of these so-called grid cells, and their role as a neuronal GPS for spatial navigation, won the 2014 Nobel Prize in Physiology or Medicine for Norwegian scientists Edvard Moser and May-Britt Moser. Now, it seems that the brain may make maps of abstract realms, too. On p. 1464, a team at the University of Oxford provides evidence that gridlike neuronal activity throughout the brain helps people organize nonnavigation knowledge—for the purposes of the new study, differences in body shape between various types of birds.

    Description: "This missing science of heredity … is, in simple truth, ten times more important to humanity than all the chemistry and physics, all the technical and industrial science that ever has been or ever will be discovered," wrote H. G. Wells in 1903. Having dedicated more than 500 pages to the topic in his new book, The Gene, Siddhartha Mukherjee would seem to agree. The book examines human genetics, from its philosophical roots in the work of Aristotle, through Gregor Mendel's garden and Thomas Hunt Morgan's work on fruitflies, and including active work in genome editing.

    Description: The specter of neurodegenerative disease, particularly Alzheimer's disease, haunts the developed world and exacts a poorly documented toll on underdeveloped countries. With so little progress made toward finding a cure—or, better, a prevention—it is time to rethink the path to progress. This requires a change in perspective on the type of research that will make a difference. The lesson learned from cancer research is that a new commitment means rethinking the fundamental approach to the disease. Cancer research moved from taking potshots with, usually, cytotoxic drugs to a bottom-up, mechanism-based approach in which newly acquired genetic knowledge played the largest role. Today, that effort has produced a platform of knowledge from which academia and industry are drawing. For neurodegenerative disease, the genetic approach remains valid but the problem must concurrently be approached from a complementary, robust cell biological perspective, focusing on the cellular cascade of events that lead to neuronal cell death.

    Description: Temporal lobe epilepsy (TLE) is characterized by debilitating, recurring seizures and an increased risk for cognitive deficits. Mossy cells (MCs) are key neurons in the hippocampal excitatory circuit, and the partial loss of MCs is a major hallmark of TLE. We investigated how MCs contribute to spontaneous ictal activity and to spatial contextual memory in a mouse model of TLE with hippocampal sclerosis, using a combination of optogenetic, electrophysiological, and behavioral approaches. In chronically epileptic mice, real-time optogenetic modulation of MCs during spontaneous hippocampal seizures controlled the progression of activity from an electrographic to convulsive seizure. Decreased MC activity is sufficient to impede encoding of spatial context, recapitulating observed cognitive deficits in chronically epileptic mice.

    Description: Developmental enhancers mediate on/off patterns of gene expression in specific cell types at particular stages during metazoan embryogenesis. They typically integrate multiple signals and regulatory determinants to achieve precise spatiotemporal expression. Such enhancers can map quite far—one megabase or more—from the genes they regulate. How remote enhancers relay regulatory information to their target promoters is one of the central mysteries of genome organization and function. A variety of contrasting mechanisms have been proposed over the years, including enhancer tracking, linking, looping, and mobilization to transcription factories. We argue that extreme versions of these mechanisms cannot account for the transcriptional dynamics and precision seen in living cells, tissues, and embryos. We describe emerging evidence for dynamic three-dimensional hubs that combine different elements of the classical models.

    Description: The classical model of cytosine DNA methylation (the presence of 5-methylcytosine, 5mC) regulation depicts this covalent modification as a stable repressive regulator of promoter activity. However, whole-genome analysis of 5mC reveals widespread tissue- and cell type–specific patterns and pervasive dynamics during mammalian development. Here we review recent findings that delineate 5mC functions in developmental stages and diverse genomic compartments as well as discuss the molecular mechanisms that connect transcriptional regulation and 5mC. Beyond the newly appreciated dynamics, regulatory roles for 5mC have been suggested in new biological contexts, such as learning and memory or aging. The use of new single-cell measurement techniques and precise editing tools will enable functional analyses of 5mC in gene expression, clarifying its role in various biological processes.

    Description: Although we can increasingly measure transcription, chromatin, methylation, and other aspects of molecular biology at single-cell resolution, most assays survey only one aspect of cellular biology. Here we describe sci-CAR, a combinatorial indexing–based coassay that jointly profiles chromatin accessibility and mRNA (CAR) in each of thousands of single cells. As a proof of concept, we apply sci-CAR to 4825 cells, including a time series of dexamethasone treatment, as well as to 11,296 cells from the adult mouse kidney. With the resulting data, we compare the pseudotemporal dynamics of chromatin accessibility and gene expression, reconstruct the chromatin accessibility profiles of cell types defined by RNA profiles, and link cis-regulatory sites to their target genes on the basis of the covariance of chromatin accessibility and transcription across large numbers of single cells.

    Description: Glia constitute roughly half of the cells of the central nervous system (CNS) but were long-considered to be static bystanders to its formation and function. Here we provide an overview of how the diverse and dynamic functions of glial cells orchestrate essentially all aspects of nervous system formation and function. Radial glia, astrocytes, oligodendrocyte progenitor cells, oligodendrocytes, and microglia each influence nervous system development, from neuronal birth, migration, axon specification, and growth through circuit assembly and synaptogenesis. As neural circuits mature, distinct glia fulfill key roles in synaptic communication, plasticity, homeostasis, and network-level activity through dynamic monitoring and alteration of CNS structure and function. Continued elucidation of glial cell biology, and the dynamic interactions of neurons and glia, will enrich our understanding of nervous system formation, health, and function.

    Description: To understand how neurons assemble to form functional circuits, it is necessary to obtain a detailed knowledge of their diversity and to define the developmental specification programs that give rise to this diversity. Invertebrates and vertebrates appear to share common developmental principles of neuronal specification in which cascades of transcription factors temporally pattern progenitors, while spatial cues modify the outcomes of this temporal patterning. Here, we highlight these conserved mechanisms and describe how they are used in distinct neural structures. We present the questions that remain for a better understanding of neuronal specification. Single-cell RNA profiling approaches will potentially shed light on these questions, allowing not only the characterization of neuronal diversity in adult brains, but also the investigation of the developmental trajectories leading to the generation and maintenance of this diversity.

    Description: Which memories are retained, where, and in what form depends on a long afterlife of the acquired information in the brain. Initial steps of consolidation may be completed within a few hours during wakefulness, but other forms of postacquisition processing take longer, extending into sleep (1, 2). The relationship between brain activity during sleep and memory consolidation remains controversial and poorly understood. On page 812 of this issue, Boyce et al. (3) demonstrate that a distinct form of hippocampal neural activity, called theta oscillation, is critical for memory formation during the rapid eye movement (REM) phase of sleep.

    Description: Last week, at the Sixth Annual Traumatic Brain Injury Conference in Arlington, Virginia, neurologist Samuel Gandy presented a former National Football League player's positron emission tomography (PET) scan as the "most dramatic" evidence yet of chronic traumatic encephalopathy (CTE) in a living person. "I've never seen anything like it," he said of the scan, which used a PET tracer called T807 to reveal deposits of a sticky, helical protein called tau in the player's brain. The announcement could represent a milestone for tau imaging, a promising but controversial strategy for diagnosing neurodegenerative diseases such as Alzheimer's in living patients. If the science pans out, it could also transform the medical and legal status of CTE, which at present can only be officially diagnosed after death, when a pathologist looks for tau in brain tissue.

    Description: Earlier this month, György Buzsáki of New York University in New York City showed a slide that sent a murmur through an audience in the Grand Ballroom of New York's Midtown Hilton during the annual meeting of the Cognitive Neuroscience Society. It wasn't just the grisly image of a human cadaver with more than 200 electrodes inserted into its brain that set people whispering; it was what those electrodes detected—or rather, what they failed to detect. When Buzsáki and his colleague, Antal Berényi of the University of Szeged in Hungary, mimicked an increasingly popular form of brain stimulation by applying alternating electrical current to the outside of the cadaver's skull, the electrodes inside registered little. Hardly any current entered the brain. On closer study, the pair discovered that up to 90% of the current had been redirected by the skin covering the skull, which acted as a "shunt," Buzsáki said. For many meeting attendees, the unusual study heightened serious doubts about the mechanism and effectiveness of transcranial direct current stimulation, an experimental, noninvasive treatment that uses electrodes to deliver weak current to a person's scalp or forehead.

    Description: The worldwide human obesity epidemic has provoked a great deal of experimentation to understand the biological controls of energy expenditure and food intake, two processes that together determine energy balance. Because food intake relies on feeding behavior that is determined by the brain, studies have focused on how the central nervous system receives and behaviorally responds to signals of metabolic status. On page 1293 of this issue, Lagerlöf et al. (1) report that a glycosylation enzyme serves as a neuronal nutrient sensor that is critical in the control of food intake and body weight. Author: Gary J.

    Description: Changes in gene regulatory networks (GRNs) underlie many phenotypic differences between species. However, the mechanisms of GRN evolution are still being debated (1–5). Explaining how GRNs originate, diversify, and maintain their identities despite regulatory element turnover is essential for developing mechanistic explanations for the origin, diversification, and conservation of homologous characters between species. Among the major outstanding questions in GRN evolution is whether individual cis-regulatory elements arise de novo through the gradual accumulation of mutations that increase the regulatory potential of existing DNA or whether cis-regulatory elements originate more rapidly through concerted processes. On page 1083 of this issue, Chuong et al. provide evidence that concerted processes, involving endogenous retroviruses (ERVs), which are remarkably abundant in mammalian genomes, have contributed to the evolution of the regulatory systems that control the mammalian immune system (6).

    Description: Contrary to classical economic supposition (1), understanding people's preferences and decisions is not as simple as observing their actions. Indeed, there are many reasons for behaving altruistically, such as being moved by someone's suffering (empathy) or feeling obliged to return a favor (reciprocity) (2, 3). One of the major challenges for social psychologists and neuroscientists is to characterize the different motives underlying our interactions with other people. On page 1074 in this issue, Hein et al. (4) show that knowing how distinct areas in the human brain communicate with each other can tell us why someone behaves altruistically.

    Description: Brain electrical activity differs markedly between wakefulness and sleep. Concomitant shifts in the ion composition of brain extracellular fluids were thought to be a consequence rather than a cause of the sleep-wake–dependent changes in neuronal activity. On page 550 of this issue, Ding et al. (1) report the surprising observation that ionic changes in the extracellular fluid are a potent control of sleep-wake–dependent neuronal activity.

    Description: Neuroscience is becoming big science, with the 2013 launches of the European Union's Human Brain Project and the United States's Brain Research through Advancing Innovative Neurotechnology (BRAIN) initiative leading the way. Last week, leaders of these massive, multi-institution projects and others around the world met at Johns Hopkins University in Baltimore, Maryland, to discuss an even loftier goal: a global neuroscience collaboration that would link their efforts and rival big science investments in astronomy and physics. More than 60 neuroscientists from 12 countries pitched diverse visions for such a project at the meeting, sponsored by the Kavli Foundation and the National Science Foundation.

    Description: Clinical observations indicate that the paramedian region of the thalamus is a critical node for controlling wakefulness. However, the specific nucleus and neural circuitry for this function remain unknown. Using in vivo fiber photometry or multichannel electrophysiological recordings in mice, we found that glutamatergic neurons of the paraventricular thalamus (PVT) exhibited high activities during wakefulness. Suppression of PVT neuronal activity caused a reduction in wakefulness, whereas activation of PVT neurons induced a transition from sleep to wakefulness and an acceleration of emergence from general anesthesia. Moreover, our findings indicate that the PVT–nucleus accumbens projections and hypocretin neurons in the lateral hypothalamus to PVT glutamatergic neurons’ projections are the effector pathways for wakefulness control. These results demonstrate that the PVT is a key wakefulness-controlling nucleus in the thalamus.

    Description: The salience of behaviorally relevant stimuli is dynamic and influenced by internal state and external environment. Monitoring such changes is critical for effective learning and flexible behavior, but the neuronal substrate for tracking the dynamics of stimulus salience is obscure. We found that neurons in the paraventricular thalamus (PVT) are robustly activated by a variety of behaviorally relevant events, including novel ("unfamiliar") stimuli, reinforcing stimuli and their predicting cues, as well as omission of the expected reward. PVT responses are scaled with stimulus intensity and modulated by changes in homeostatic state or behavioral context. Inhibition of the PVT responses suppresses appetitive or aversive associative learning and reward extinction. Our findings demonstrate that the PVT gates associative learning by providing a dynamic representation of stimulus salience.

    Description: Animals constantly update their body posture to meet behavioral demands, but little is known about the neural signals on which this depends. We therefore tracked freely foraging rats in three dimensions while recording from the posterior parietal cortex (PPC) and the frontal motor cortex (M2), areas critical for movement planning and navigation. Both regions showed strong tuning to posture of the head, neck, and back, but signals for movement were much less dominant. Head and back representations were organized topographically across the PPC and M2, and more neurons represented postures that occurred less often. Simultaneous recordings across areas were sufficiently robust to decode ongoing behavior and showed that spiking in the PPC tended to precede that in M2. Both the PPC and M2 strongly represent posture by using a spatially organized, energetically efficient population code.

    Description: Memory resides in engram cells distributed across the brain. However, the site-specific substrate within these engram cells remains theoretical, even though it is generally accepted that synaptic plasticity encodes memories. We developed the dual-eGRASP (green fluorescent protein reconstitution across synaptic partners) technique to examine synapses between engram cells to identify the specific neuronal site for memory storage. We found an increased number and size of spines on CA1 engram cells receiving input from CA3 engram cells. In contextual fear conditioning, this enhanced connectivity between engram cells encoded memory strength. CA3 engram to CA1 engram projections strongly occluded long-term potentiation. These results indicate that enhanced structural and functional connectivity between engram cells across two directly connected brain regions forms the synaptic correlate for memory formation.

    Description: Consumer genomics databases have reached the scale of millions of individuals. Recently, law enforcement authorities have exploited some of these databases to identify suspects via distant familial relatives. Using genomic data of 1.28 million individuals tested with consumer genomics, we investigated the power of this technique. We project that about 60% of the searches for individuals of European descent will result in a third-cousin or closer match, which theoretically allows their identification using demographic identifiers. Moreover, the technique could implicate nearly any U.S. individual of European descent in the near future. We demonstrate that the technique can also identify research participants of a public sequencing project. On the basis of these results, we propose a potential mitigation strategy and policy implications for human subject research.

    Description: Consolidation of spatial and episodic memories is thought to rely on replay of neuronal activity sequences during sleep. However, the network dynamics underlying the initial storage of memories during wakefulness have never been tested. Although slow, behavioral time scale sequences have been claimed to sustain sequential memory formation, fast ("theta") time scale sequences, nested within slow sequences, could be instrumental. We found that in rats traveling passively on a model train, place cells formed behavioral time scale sequences but theta sequences were degraded, resulting in impaired subsequent sleep replay. In contrast, when the rats actively ran on a treadmill while being transported on the train, place cells generated clear theta sequences and accurate trajectory replay during sleep. Our results support the view that nested sequences underlie the initial formation of memory traces subsequently consolidated during sleep.

    Description: Current genetic data are equivocal as to whether goat domestication occurred multiple times or was a singular process. We generated genomic data from 83 ancient goats (51 with genome-wide coverage) from Paleolithic to Medieval contexts throughout the Near East. Our findings demonstrate that multiple divergent ancient wild goat sources were domesticated in a dispersed process that resulted in genetically and geographically distinct Neolithic goat populations, echoing contemporaneous human divergence across the region. These early goat populations contributed differently to modern goats in Asia, Africa, and Europe. We also detect early selection for pigmentation, stature, reproduction, milking, and response to dietary change, providing 8000-year-old evidence for human agency in molding genome variation within a partner species.

    Description: Whether fear attenuation is mediated by inhibition of the original memory trace of fear with a new memory trace of safety or by updating of the original fear trace toward safety has been a long-standing question in neuroscience and psychology alike. In particular, which of the two scenarios underlies the attenuation of remote (month-old) fear memories is completely unknown, despite the impetus to better understand this process against the backdrop of enduring traumata. We found—chemogenetically and in an engram-specific manner—that effective remote fear attenuation is accompanied by the reactivation of memory recall–induced neurons in the dentate gyrus and that the continued activity of these neurons is critical for fear reduction. This suggests that the original memory trace of fear actively contributes to remote fear attenuation.

    Description: Technical advances have enabled the collection of genome and transcriptome data sets with single-cell resolution. However, single-cell characterization of the epigenome has remained challenging. Furthermore, because cells must be physically separated before biochemical processing, conventional single-cell preparatory methods scale linearly. We applied combinatorial cellular indexing to measure chromatin accessibility in thousands of single cells per assay, circumventing the need for compartmentalization of individual cells. We report chromatin accessibility profiles from more than 15,000 single cells and use these data to cluster cells on the basis of chromatin accessibility landscapes. We identify modules of coordinately regulated chromatin accessibility at the level of single cells both between and within cell types, with a scalable method that may accelerate progress toward a human cell atlas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cusanovich, Darren A -- Daza, Riza -- Adey, Andrew -- Pliner, Hannah A -- Christiansen, Lena -- Gunderson, Kevin L -- Steemers, Frank J -- Trapnell, Cole -- Shendure, Jay -- 1DP1HG007811/DP/NCCDPHP CDC HHS/ -- New York, N.Y. -- Science. 2015 May 22;348(6237):910-4. doi: 10.1126/science.aab1601.

    Description: Microbes are dominant drivers of biogeochemical processes, yet drawing a global picture of functional diversity, microbial community structure, and their ecological determinants remains a grand challenge. We analyzed 7.2 terabases of metagenomic data from 243 Tara Oceans samples from 68 locations in epipelagic and mesopelagic waters across the globe to generate an ocean microbial reference gene catalog with 〉40 million nonredundant, mostly novel sequences from viruses, prokaryotes, and picoeukaryotes. Using 139 prokaryote-enriched samples, containing 〉35,000 species, we show vertical stratification with epipelagic community composition mostly driven by temperature rather than other environmental factors or geography. We identify ocean microbial core functionality and reveal that 〉73% of its abundance is shared with the human gut microbiome despite the physicochemical differences between these two ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sunagawa, Shinichi -- Coelho, Luis Pedro -- Chaffron, Samuel -- Kultima, Jens Roat -- Labadie, Karine -- Salazar, Guillem -- Djahanschiri, Bardya -- Zeller, Georg -- Mende, Daniel R -- Alberti, Adriana -- Cornejo-Castillo, Francisco M -- Costea, Paul I -- Cruaud, Corinne -- d'Ovidio, Francesco -- Engelen, Stefan -- Ferrera, Isabel -- Gasol, Josep M -- Guidi, Lionel -- Hildebrand, Falk -- Kokoszka, Florian -- Lepoivre, Cyrille -- Lima-Mendez, Gipsi -- Poulain, Julie -- Poulos, Bonnie T -- Royo-Llonch, Marta -- Sarmento, Hugo -- Vieira-Silva, Sara -- Dimier, Celine -- Picheral, Marc -- Searson, Sarah -- Kandels-Lewis, Stefanie -- Tara Oceans coordinators -- Bowler, Chris -- de Vargas, Colomban -- Gorsky, Gabriel -- Grimsley, Nigel -- Hingamp, Pascal -- Iudicone, Daniele -- Jaillon, Olivier -- Not, Fabrice -- Ogata, Hiroyuki -- Pesant, Stephane -- Speich, Sabrina -- Stemmann, Lars -- Sullivan, Matthew B -- Weissenbach, Jean -- Wincker, Patrick -- Karsenti, Eric -- Raes, Jeroen -- Acinas, Silvia G -- Bork, Peer -- New York, N.Y. -- Science. 2015 May 22;348(6237):1261359. doi: 10.1126/science.1261359.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural and Computational Biology, European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany. sunagawa@embl.de karsenti@embl.de jeroen.raes@vib-kuleuven.be sacinas@icm.csic.es bork@embl.de. ; Structural and Computational Biology, European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany. ; Department of Microbiology and Immunology, Rega Institute, KU Leuven, Herestraat 49, 3000 Leuven, Belgium.

    Description: Jan et al. (Research Articles, 7 November 2014, p. 716) propose that ribosomes translating secretome messenger RNAs (mRNAs) traffic from the cytosol to the endoplasmic reticulum (ER) upon emergence of the signal peptide and return to the cytosol after termination. An accounting of controls demonstrates that mRNAs initiate translation on ER-bound ribosomes and that ribosomes are retained on the ER through many cycles of translation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reid, David W -- Nicchitta, Christopher V -- GM101533/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Jun 12;348(6240):1217. doi: 10.1126/science.aaa7257.

    Description: According to the disease module hypothesis, the cellular components associated with a disease segregate in the same neighborhood of the human interactome, the map of biologically relevant molecular interactions. Yet, given the incompleteness of the interactome and the limited knowledge of disease-associated genes, it is not obvious if the available data have sufficient coverage to map out modules associated with each disease. Here we derive mathematical conditions for the identifiability of disease modules and show that the network-based location of each disease module determines its pathobiological relationship to other diseases. For example, diseases with overlapping network modules show significant coexpression patterns, symptom similarity, and comorbidity, whereas diseases residing in separated network neighborhoods are phenotypically distinct. These tools represent an interactome-based platform to predict molecular commonalities between phenotypically related diseases, even if they do not share primary disease genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4435741/" 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/PMC4435741/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Menche, Jorg -- Sharma, Amitabh -- Kitsak, Maksim -- Ghiassian, Susan Dina -- Vidal, Marc -- Loscalzo, Joseph -- Barabasi, Albert-Laszlo -- P01-HL083069/HL/NHLBI NIH HHS/ -- P50 HG004233/HG/NHGRI NIH HHS/ -- P50-HG004233/HG/NHGRI NIH HHS/ -- R37 HL061795/HL/NHLBI NIH HHS/ -- R37-HL061795/HL/NHLBI NIH HHS/ -- RC2-HL101543/HL/NHLBI NIH HHS/ -- U01 HG001715/HG/NHGRI NIH HHS/ -- U01 HG007690/HG/NHGRI NIH HHS/ -- U01 HL108630/HL/NHLBI NIH HHS/ -- U01-HG001715/HG/NHGRI NIH HHS/ -- U01-HG007690/HG/NHGRI NIH HHS/ -- U01-HL108630/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):1257601. doi: 10.1126/science.1257601.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Complex Networks Research and Department of Physics, Northeastern University, 110 Forsyth Street, 111 Dana Research Center, Boston, MA 02115, USA.

    Description: Transcriptional regulation and posttranscriptional processing underlie many cellular and organismal phenotypes. We used RNA sequence data generated by Genotype-Tissue Expression (GTEx) project to investigate the patterns of transcriptome variation across individuals and tissues. Tissues exhibit characteristic transcriptional signatures that show stability in postmortem samples. These signatures are dominated by a relatively small number of genes-which is most clearly seen in blood-though few are exclusive to a particular tissue and vary more across tissues than individuals. Genes exhibiting high interindividual expression variation include disease candidates associated with sex, ethnicity, and age. Primary transcription is the major driver of cellular specificity, with splicing playing mostly a complementary role; except for the brain, which exhibits a more divergent splicing program. Variation in splicing, despite its stochasticity, may play in contrast a comparatively greater role in defining individual phenotypes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4547472/" 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/PMC4547472/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mele, Marta -- Ferreira, Pedro G -- Reverter, Ferran -- DeLuca, David S -- Monlong, Jean -- Sammeth, Michael -- Young, Taylor R -- Goldmann, Jakob M -- Pervouchine, Dmitri D -- Sullivan, Timothy J -- Johnson, Rory -- Segre, Ayellet V -- Djebali, Sarah -- Niarchou, Anastasia -- GTEx Consortium -- Wright, Fred A -- Lappalainen, Tuuli -- Calvo, Miquel -- Getz, Gad -- Dermitzakis, Emmanouil T -- Ardlie, Kristin G -- Guigo, Roderic -- HHSN261200800001E/PHS HHS/ -- HHSN268201000029C/HL/NHLBI NIH HHS/ -- HHSN268201000029C/PHS HHS/ -- R01 DA006227-17/DA/NIDA NIH HHS/ -- R01 MH090936/MH/NIMH NIH HHS/ -- R01 MH090941/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2015 May 8;348(6235):660-5. doi: 10.1126/science.aaa0355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genomic Regulation (CRG), Barcelona, Catalonia, Spain.

    Description: Human higher cognition is attributed to the evolutionary expansion and elaboration of the human cerebral cortex. However, the genetic mechanisms contributing to these developmental changes are poorly understood. We used comparative epigenetic profiling of human, rhesus macaque, and mouse corticogenesis to identify promoters and enhancers that have gained activity in humans. These gains are significantly enriched in modules of coexpressed genes in the cortex that function in neuronal proliferation, migration, and cortical-map organization. Gain-enriched modules also showed correlated gene expression patterns and similar transcription factor binding site enrichments in promoters and enhancers, suggesting that they are connected by common regulatory mechanisms. Our results reveal coordinated patterns of potential regulatory changes associated with conserved developmental processes during corticogenesis, providing insight into human cortical evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4426903/" 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/PMC4426903/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reilly, Steven K -- Yin, Jun -- Ayoub, Albert E -- Emera, Deena -- Leng, Jing -- Cotney, Justin -- Sarro, Richard -- Rakic, Pasko -- Noonan, James P -- 099175/Z/12/Z/Wellcome Trust/United Kingdom -- DA023999/DA/NIDA NIH HHS/ -- F32 GM106628/GM/NIGMS NIH HHS/ -- GM094780/GM/NIGMS NIH HHS/ -- NS014841/NS/NINDS NIH HHS/ -- P30 CA016359/CA/NCI NIH HHS/ -- R01 DA023999/DA/NIDA NIH HHS/ -- R01 GM094780/GM/NIGMS NIH HHS/ -- T32 GM007223/GM/NIGMS NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Mar 6;347(6226):1155-9. doi: 10.1126/science.1260943.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Yale School of Medicine, New Haven, CT 06510, USA. ; Kavli Institute for Neuroscience, Yale School of Medicine, New Haven, CT 06510, USA.

    Description: Paradigms of sustainable exploitation focus on population dynamics of prey and yields to humanity but ignore the behavior of humans as predators. We compared patterns of predation by contemporary hunters and fishers with those of other predators that compete over shared prey (terrestrial mammals and marine fishes). Our global survey (2125 estimates of annual finite exploitation rate) revealed that humans kill adult prey, the reproductive capital of populations, at much higher median rates than other predators (up to 14 times higher), with particularly intense exploitation of terrestrial carnivores and fishes. Given this competitive dominance, impacts on predators, and other unique predatory behavior, we suggest that humans function as an unsustainable "super predator," which-unless additionally constrained by managers-will continue to alter ecological and evolutionary processes globally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Darimont, Chris T -- Fox, Caroline H -- Bryan, Heather M -- Reimchen, Thomas E -- New York, N.Y. -- Science. 2015 Aug 21;349(6250):858-60. doi: 10.1126/science.aac4249.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography, University of Victoria, Post Office Box 1700, Station CSC, Victoria, British Columbia V8W 2Y2, Canada.

    Description: Insulin-induced gene 1 (Insig-1) and Insig-2 are endoplasmic reticulum membrane-embedded sterol sensors that regulate the cellular accumulation of sterols. Despite their physiological importance, the structural information on Insigs remains limited. Here we report the high-resolution structures of MvINS, an Insig homolog from Mycobacterium vanbaalenii. MvINS exists as a homotrimer. Each protomer comprises six transmembrane segments (TMs), with TM3 and TM4 contributing to homotrimerization. The six TMs enclose a V-shaped cavity that can accommodate a diacylglycerol molecule. A homology-based structural model of human Insig-2, together with biochemical characterizations, suggest that the central cavity of Insig-2 accommodates 25-hydroxycholesterol, whereas TM3 and TM4 engage in Scap binding. These analyses provide an important framework for further functional and mechanistic understanding of Insig proteins and the sterol regulatory element-binding protein pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4704858/" 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/PMC4704858/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ren, Ruobing -- Zhou, Xinhui -- He, Yuan -- Ke, Meng -- Wu, Jianping -- Liu, Xiaohui -- Yan, Chuangye -- Wu, Yixuan -- Gong, Xin -- Lei, Xiaoguang -- Yan, S Frank -- Radhakrishnan, Arun -- Yan, Nieng -- HL-20948/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jul 10;349(6244):187-91. doi: 10.1126/science.aab1091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Membrane Biology, Tsinghua University, Beijing 100084, China.

    Description: Protein phosphorylation regulates virtually all biological processes. Although protein kinases are popular drug targets, targeting protein phosphatases remains a challenge. Here, we describe Sephin1 (selective inhibitor of a holophosphatase), a small molecule that safely and selectively inhibited a regulatory subunit of protein phosphatase 1 in vivo. Sephin1 selectively bound and inhibited the stress-induced PPP1R15A, but not the related and constitutive PPP1R15B, to prolong the benefit of an adaptive phospho-signaling pathway, protecting cells from otherwise lethal protein misfolding stress. In vivo, Sephin1 safely prevented the motor, morphological, and molecular defects of two otherwise unrelated protein-misfolding diseases in mice, Charcot-Marie-Tooth 1B, and amyotrophic lateral sclerosis. Thus, regulatory subunits of phosphatases are drug targets, a property exploited here to safely prevent two protein misfolding diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4490275/" 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/PMC4490275/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Das, Indrajit -- Krzyzosiak, Agnieszka -- Schneider, Kim -- Wrabetz, Lawrence -- D'Antonio, Maurizio -- Barry, Nicholas -- Sigurdardottir, Anna -- Bertolotti, Anne -- 309516/European Research Council/International -- MC_U105185860/Medical Research Council/United Kingdom -- R01-NS55256/NS/NINDS NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Apr 10;348(6231):239-42. doi: 10.1126/science.aaa4484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Francis Crick Avenue, Cambridge, CB2 0QH, UK. ; Division of Genetics and Cell Biology, San Raffaele Scientific Institute, 20132 Milan, Italy. ; Medical Research Council Laboratory of Molecular Biology, Francis Crick Avenue, Cambridge, CB2 0QH, UK. aberto@mrc-lmb.cam.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25859045" target="_blank"〉PubMed〈/a〉

    Description: Werner syndrome (WS) is a premature aging disorder caused by WRN protein deficiency. Here, we report on the generation of a human WS model in human embryonic stem cells (ESCs). Differentiation of WRN-null ESCs to mesenchymal stem cells (MSCs) recapitulates features of premature cellular aging, a global loss of H3K9me3, and changes in heterochromatin architecture. We show that WRN associates with heterochromatin proteins SUV39H1 and HP1alpha and nuclear lamina-heterochromatin anchoring protein LAP2beta. Targeted knock-in of catalytically inactive SUV39H1 in wild-type MSCs recapitulates accelerated cellular senescence, resembling WRN-deficient MSCs. Moreover, decrease in WRN and heterochromatin marks are detected in MSCs from older individuals. Our observations uncover a role for WRN in maintaining heterochromatin stability and highlight heterochromatin disorganization as a potential determinant of human aging.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4494668/" 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/PMC4494668/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Weiqi -- Li, Jingyi -- Suzuki, Keiichiro -- Qu, Jing -- Wang, Ping -- Zhou, Junzhi -- Liu, Xiaomeng -- Ren, Ruotong -- Xu, Xiuling -- Ocampo, Alejandro -- Yuan, Tingting -- Yang, Jiping -- Li, Ying -- Shi, Liang -- Guan, Dee -- Pan, Huize -- Duan, Shunlei -- Ding, Zhichao -- Li, Mo -- Yi, Fei -- Bai, Ruijun -- Wang, Yayu -- Chen, Chang -- Yang, Fuquan -- Li, Xiaoyu -- Wang, Zimei -- Aizawa, Emi -- Goebl, April -- Soligalla, Rupa Devi -- Reddy, Pradeep -- Esteban, Concepcion Rodriguez -- Tang, Fuchou -- Liu, Guang-Hui -- Belmonte, Juan Carlos Izpisua -- F32 AG047770/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 Jun 5;348(6239):1160-3. doi: 10.1126/science.aaa1356.

    Description: During rest, brain activity is synchronized between different regions widely distributed throughout the brain, forming functional networks. However, the molecular mechanisms supporting functional connectivity remain undefined. We show that functional brain networks defined with resting-state functional magnetic resonance imaging can be recapitulated by using measures of correlated gene expression in a post mortem brain tissue data set. The set of 136 genes we identify is significantly enriched for ion channels. Polymorphisms in this set of genes significantly affect resting-state functional connectivity in a large sample of healthy adolescents. Expression levels of these genes are also significantly associated with axonal connectivity in the mouse. The results provide convergent, multimodal evidence that resting-state functional networks correlate with the orchestrated activity of dozens of genes linked to ion channel activity and synaptic function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richiardi, Jonas -- Altmann, Andre -- Milazzo, Anna-Clare -- Chang, Catie -- Chakravarty, M Mallar -- Banaschewski, Tobias -- Barker, Gareth J -- Bokde, Arun L W -- Bromberg, Uli -- Buchel, Christian -- Conrod, Patricia -- Fauth-Buhler, Mira -- Flor, Herta -- Frouin, Vincent -- Gallinat, Jurgen -- Garavan, Hugh -- Gowland, Penny -- Heinz, Andreas -- Lemaitre, Herve -- Mann, Karl F -- Martinot, Jean-Luc -- Nees, Frauke -- Paus, Tomas -- Pausova, Zdenka -- Rietschel, Marcella -- Robbins, Trevor W -- Smolka, Michael N -- Spanagel, Rainer -- Strohle, Andreas -- Schumann, Gunter -- Hawrylycz, Mike -- Poline, Jean-Baptiste -- Greicius, Michael D -- IMAGEN consortium -- 93558/Medical Research Council/United Kingdom -- R01 MH085772-01A1/MH/NIMH NIH HHS/ -- R01NS073498/NS/NINDS NIH HHS/ -- U54 EB020403/EB/NIBIB NIH HHS/ -- Department of Health/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Jun 12;348(6240):1241-4. doi: 10.1126/science.1255905.

    Description: Telomeres are the protective end-complexes at the termini of eukaryotic chromosomes. Telomere attrition can lead to potentially maladaptive cellular changes, block cell division, and interfere with tissue replenishment. Recent advances in the understanding of human disease processes have clarified the roles of telomere biology, especially in diseases of human aging and in some aging-related processes. Greater overall telomere attrition predicts mortality and aging-related diseases in inherited telomere syndrome patients, and also in general human cohorts. However, genetically caused variations in telomere maintenance either raise or lower risks and progression of cancers, in a highly cancer type-specific fashion. Telomere maintenance is determined by genetic factors and is also cumulatively shaped by nongenetic influences throughout human life; both can interact. These and other recent findings highlight both causal and potentiating roles for telomere attrition in human diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blackburn, Elizabeth H -- Epel, Elissa S -- Lin, Jue -- CA096840/CA/NCI NIH HHS/ -- GM026259/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1193-8. doi: 10.1126/science.aab3389.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco, CA 94143, USA. elizabeth.blackburn@ucsf.edu. ; Department of Psychiatry, University of California, San Francisco, CA 94143, USA. ; Department of Biochemistry and Biophysics, University of California, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26785477" target="_blank"〉PubMed〈/a〉

    Description: The global biogeography of microorganisms remains largely unknown, in contrast to the well-studied diversity patterns of macroorganisms. We used arbuscular mycorrhizal (AM) fungus DNA from 1014 plant-root samples collected worldwide to determine the global distribution of these plant symbionts. We found that AM fungal communities reflected local environmental conditions and the spatial distance between sites. However, despite AM fungi apparently possessing limited dispersal ability, we found 93% of taxa on multiple continents and 34% on all six continents surveyed. This contrasts with the high spatial turnover of other fungal taxa and with the endemism displayed by plants at the global scale. We suggest that the biogeography of AM fungi is driven by unexpectedly efficient dispersal, probably via both abiotic and biotic vectors, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davison, J -- Moora, M -- Opik, M -- Adholeya, A -- Ainsaar, L -- Ba, A -- Burla, S -- Diedhiou, A G -- Hiiesalu, I -- Jairus, T -- Johnson, N C -- Kane, A -- Koorem, K -- Kochar, M -- Ndiaye, C -- Partel, M -- Reier, U -- Saks, U -- Singh, R -- Vasar, M -- Zobel, M -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):970-3. doi: 10.1126/science.aab1161.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Ecology and Earth Sciences, University of Tartu, Lai 40, Tartu 51005, Estonia. ; Centre for Mycorrhizal Research, The Energy and Resources Institute (TERI), India Habitat Centre, Lodhi Road, New Delhi 110 003, India. ; Laboratoire des Symbioses Tropicales et Mediterraneennes, Unite Mixte de Recherche 113, Laboratoire de Biologie et Physiologie Vegetales, Faculte des Sciences Exactes et Naturelles, Universite des Antilles, BP 592, 97159, Pointe-a-Pitre, Guadeloupe (French West Indies). ; Laboratoire Commun de Microbiologie de l'Institut de Recherche pour le Developpement-Institut Senegalais de Recherches Agricoles-Universite Cheikh Anta Diop (UCAD), Departement de Biologie Vegetale, UCAD, BP 5005 Dakar, Senegal. ; Institute of Ecology and Earth Sciences, University of Tartu, Lai 40, Tartu 51005, Estonia.

    Description: Metagenomic sequencing increased our understanding of the role of the microbiome in health and disease, yet it only provides a snapshot of a highly dynamic ecosystem. Here, we show that the pattern of metagenomic sequencing read coverage for different microbial genomes contains a single trough and a single peak, the latter coinciding with the bacterial origin of replication. Furthermore, the ratio of sequencing coverage between the peak and trough provides a quantitative measure of a species' growth rate. We demonstrate this in vitro and in vivo, under different growth conditions, and in complex bacterial communities. For several bacterial species, peak-to-trough coverage ratios, but not relative abundances, correlated with the manifestation of inflammatory bowel disease and type II diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korem, Tal -- Zeevi, David -- Suez, Jotham -- Weinberger, Adina -- Avnit-Sagi, Tali -- Pompan-Lotan, Maya -- Matot, Elad -- Jona, Ghil -- Harmelin, Alon -- Cohen, Nadav -- Sirota-Madi, Alexandra -- Thaiss, Christoph A -- Pevsner-Fischer, Meirav -- Sorek, Rotem -- Xavier, Ramnik J -- Elinav, Eran -- Segal, Eran -- New York, N.Y. -- Science. 2015 Sep 4;349(6252):1101-6. doi: 10.1126/science.aac4812.

    Description: Infection with intestinal helminths results in immunological changes that influence co-infections, and might influence fecundity by inducing immunological states affecting conception and pregnancy. We investigated associations between intestinal helminths and fertility in women, using 9 years of longitudinal data from 986 Bolivian forager-horticulturalists, experiencing natural fertility and 70% helminth prevalence. We found that different species of helminth are associated with contrasting effects on fecundity. Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, whereas infection with hookworm is associated with delayed first pregnancy and extended interbirth intervals. Thus, helminths may have important effects on human fertility that reflect physiological and immunological consequences of infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blackwell, Aaron D -- Tamayo, Marilyne A -- Beheim, Bret -- Trumble, Benjamin C -- Stieglitz, Jonathan -- Hooper, Paul L -- Martin, Melanie -- Kaplan, Hillard -- Gurven, Michael -- P01AG022500/AG/NIA NIH HHS/ -- R01AG024119/AG/NIA NIH HHS/ -- R56AG024119/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 20;350(6263):970-2. doi: 10.1126/science.aac7902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of California Santa Barbara, CA 93106, USA.

    Description: The Ebola epidemic in West Africa has caused substantial morbidity and mortality. The outbreak has also disrupted health care services, including childhood vaccinations, creating a second public health crisis. We project that after 6 to 18 months of disruptions, a large connected cluster of children unvaccinated for measles will accumulate across Guinea, Liberia, and Sierra Leone. This pool of susceptibility increases the expected size of a regional measles outbreak from 127,000 to 227,000 cases after 18 months, resulting in 2000 to 16,000 additional deaths (comparable to the numbers of Ebola deaths reported thus far). There is a clear path to avoiding outbreaks of childhood vaccine-preventable diseases once the threat of Ebola begins to recede: an aggressive regional vaccination campaign aimed at age groups left unprotected because of health care disruptions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4691345/" 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/PMC4691345/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, Saki -- Metcalf, C Jessica E -- Ferrari, Matthew J -- Moss, William J -- Truelove, Shaun A -- Tatem, Andrew J -- Grenfell, Bryan T -- Lessler, Justin -- R01 AI102939/AI/NIAID NIH HHS/ -- U19AI089674/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1240-2. doi: 10.1126/science.aaa3438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA. ; Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA.
