    Description: History from the Bottom Up and the Inside Out James R. Barrett rethinks the boundaries of American social and labor history by investigating the ways in which working-class, radical, and immigrant people's personal lives intersected with their activism and religious, racial, ethnic, and class identities. Concerned with carving out space for individuals in the story of the working class, Barrett examines all aspects of individuals' subjective experiences, from their personalities, relationships, and emotions to their health and intellectual pursuits. Barrett's subjects include American communists, "blue-collar cosmopolitans"—such as well-read and well-traveled porters, sailors, and hoboes—and figures in early twentieth-century anarchist subculture. He also details the process of the Americanization of immigrant workers via popular culture and their development of class and racial identities, asking how immigrants learned to think of themselves as white. Throughout, Barrett enriches our understanding of working people’s lives, making it harder to objectify them as nameless cogs operating within social and political movements. In so doing, he works to redefine conceptions of work, migration, and radical politics.

    Description: In 'An Aqueous Territory' Ernesto Bassi traces the configuration of a geographic space he calls the transimperial Greater Caribbean between 1760 and 1860. Focusing on the Caribbean coast of New Granada (present-day Colombia), Bassi shows that the region's residents did not live their lives bounded by geopolitical borders. Rather, the cross-border activities of sailors, traders, revolutionaries, indigenous peoples, and others reflected their perceptions of the Caribbean as a transimperial space where trade, information, and people circulated, both conforming to and in defiance of imperial regulations. Bassi demonstrates that the islands, continental coasts, and open waters of the transimperial Greater Caribbean constituted a space that was simultaneously Spanish, British, French, Dutch, Danish, Anglo-American, African, and indigenous.

    Description: In Uneven Encounters, Micol Seigel chronicles the exchange of popular culture between Brazil and the United States in the years between the World Wars, and demonstrates how that exchange affected ideas of race and nation in both countries. From Americans interpreting advertisements for Brazilian coffee or dancing the Brazilian maxixe, to Rio musicians embracing the “foreign” qualities of jazz, Seigel traces a lively, cultural back and forth. Along the way, she shows how race and nation for both elites and non-elites are constructed together, and driven by global cultural and intellectual currents as well as local, regional, and national ones. Seigel explores the circulation of images of Brazilian coffee and of maxixe in the United States during the period just after the imperial expansions of the early twentieth century. Exoticist interpretations structured North Americans’ paradoxical sense of themselves as productive “consumer citizens.” Some people, however, could not simply assume the privileges of citizenship. In their struggles against racism, Afro-descended citizens living in Rio de Janeiro, São Paulo, New York, and Chicago encountered images and notions of each other, and found them useful. Seigel introduces readers to cosmopolitan Afro-Brazilians and African Americans who rarely traveled far from home but who nonetheless absorbed ideas from abroad. She suggests that studies comparing U.S. and Brazilian racial identities as two distinct constructions are misconceived. Racial formation transcends national borders; attempts to understand it must do the same.

    Description: Since the late 1990s, Asian nations have increasingly encouraged, facilitated, or demanded the return of emigrants. In this interdisciplinary collection, distinguished scholars from countries around the world explore the changing relations between nation-states and transnational mobility. Taking into account illegally trafficked migrants, deportees, temporary laborers on short-term contracts, and highly skilled émigrés, the contributors argue that the figure of the returnee energizes and redefines nationalism in an era of increasingly fluid and indeterminate national sovereignty. They acknowledge the diversity, complexity, and instability of reverse migration, while emphasizing its discursive, policy, and political significance at a moment when the tensions between state power and transnational subjects are particularly visible. Taken together, the essays foreground Asia as a useful site for rethinking the intersections of migration, sovereignty, and nationalism.

    Description: In the early twentieth century, Native American baskets, blankets, and bowls could be purchased from department stores, “Indian stores,” dealers, and the U.S. government’s Indian schools. Men and women across the United States indulged in a widespread passion for collecting Native American art, which they displayed in domestic nooks called “Indian corners.” Elizabeth Hutchinson identifies this collecting as part of a larger “Indian craze” and links it to other activities such as the inclusion of Native American artifacts in art exhibitions sponsored by museums, arts and crafts societies, and World’s Fairs, and the use of indigenous handicrafts as models for non-Native artists exploring formal abstraction and emerging notions of artistic subjectivity. She argues that the Indian craze convinced policymakers that art was an aspect of “traditional” Native culture worth preserving, an attitude that continues to influence popular attitudes and federal legislation. Illustrating her argument with images culled from late-nineteenth- and early-twentieth-century publications, Hutchinson revises the standard history of the mainstream interest in Native American material culture as “art.” While many locate the development of this cross-cultural interest in the Southwest after the First World War, Hutchinson reveals that it began earlier and spread across the nation from west to east and from reservation to metropolis. She demonstrates that artists, teachers, and critics associated with the development of American modernism, including Arthur Wesley Dow and Gertrude Käsebier, were inspired by Native art. Native artists were also able to achieve some recognition as modern artists, as Hutchinson shows through her discussion of the Winnebago painter and educator Angel DeCora. By taking a transcultural approach, Hutchinson transforms our understanding of the role of Native Americans in modernist culture.

    Description: Presenting an unprecedented, integrated view of migration in North America, this interdisciplinary collection of essays illuminates the movements of people within and between Canada, the Caribbean, Mexico, and the United States over the past two centuries. Several essays discuss recent migrations from Central America as well. In the introduction, Dirk Hoerder provides a sweeping historical overview of North American societies in the Atlantic world. He also develops and advocates what he and Nora Faires call “transcultural societal studies,” an interdisciplinary approach to migration studies that combines migration research across disciplines and at the local, regional, national, and transnational levels. The contributors examine the movements of diverse populations across North America in relation to changing cultural, political, and economic patterns.

    Description: In DISCIPLINARY CONQUEST, Ricardo Salvatore argues that the foundation of the discipline of Latin American studies, pioneered between 1900 and 1945, was linked to the United States’s business and financial interests and informal imperialism. In contrast, the consolidation of Latin American studies has traditionally been placed in the 1960s, as a reaction to the Cuban Revolution. Focusing on five representative U.S. scholars of South America—historian Clarence Haring, geographer Isaiah Bowman, political scientist Leo Rowe, sociologist Edward Ross, and archaeologist Hiram Bingham -- Salvatore demonstrates how their search for comprehensive knowledge about South America can be understood as a contribution to hemispheric hegemony, an intellectual conquest of the region. U.S. economic leaders, diplomats, and foreign-policy experts needed knowledge about the region to expand investment and trade, as well as the U.S.’s international influence

    Description: 'Thinking Literature across Continents' finds Ranjan Ghosh and J. Hillis Miller—two thinkers from different continents, cultures, training, and critical perspectives—debating and reflecting upon what literature is and why it matters. Ghosh and Miller do not attempt to formulate a joint theory of literature; rather, they allow their different backgrounds and lively disagreements to stimulate generative dialogue on poetry, world literature, pedagogy, and the ethics of literature. Addressing a varied literary context ranging from Victorian literature, Chinese literary criticism and philosophy, and continental philosophy to Sanskrit poetics and modern European literature, Ghosh offers a transnational theory of literature while Miller emphasizes the need to account for what a text says and how it says it. This book highlights two minds continually discovering new paths of communication and two literary and cultural traditions intersecting in productive and compelling ways.

    Description: Between 1750 and 1870 the world faced transformations marked by the rise of industrial capitalism, the fall of European empires in the Americas, and the rise of nations there. 'New Countries' explores how these events transformed the Americas in diverging ways. Up to 1790, Saint Domingue’s sugar and slave economy drove Atlantic trades; then revolutionary slaves made Haiti, freeing themselves and ending export production. New Spain’s silver fueled global trades until Bajío insurgents collapsed silver capitalism and undermined Spanish rule after 1810. The fall of silver left regions from Mexico through Guatemala and the Andes in search of new polities and economies. After 1870 the United States became an agro-industrial hegemon, most American nations turned to commodity exports, and Haitians and diverse indigenous peoples struggled to keep independent lives beyond the reach of industrial powers seeking supplies and markets.

    Description: From Skirts Ahoy! to M*A*S*H, Private Benjamin, G.I. Jane, and JAG, films and television shows have grappled with the notion that military women are contradictory figures, unable to be both effective soldiers and appropriately feminine. In Soldiers’ Stories, Yvonne Tasker traces this perceived paradox across genres including musicals, screwball comedies, and action thrillers. She explains how, during the Second World War, women were portrayed as auxiliaries, temporary necessities of “total war.” Later, nursing, with its connotations of feminine care, offered a solution to the “gender problem.” From the 1940s through the 1970s, musicals, romances, and comedies exploited the humorous potential of the gender role reversal that the military woman was taken to represent. Since the 1970s, female soldiers have appeared most often in thrillers and legal and crime dramas, cast as isolated figures, sometimes victimized and sometimes heroic. Soldiers’ Stories is a comprehensive ...

    Description: Chronicling the dramatic history of the Brazilian Amazon during the Second World War, Seth Garfield provides fresh perspectives on contemporary environmental debates. His multifaceted analysis explains how the Amazon became the object of geopolitical rivalries, state planning, media coverage, popular fascination, and social conflict. In need of rubber, a vital war material, the United States spent millions of dollars to revive the Amazon's rubber trade. In the name of development and national security, Brazilian officials implemented public programs to engineer the hinterland's transformation. Migrants from Brazil's drought-stricken Northeast flocked to the Amazon in search of work. In defense of traditional ways of life, longtime Amazon residents sought to temper outside intervention.

    Description: Years of surveillance-related leaks from US whistleblower Edward Snowden have fuelled an international debate on privacy, spying, and Internet surveillance. Much of the focus has centered on the role of the US National Security Agency, yet there is an important Canadian side to the story. The Communications Security Establishment, the Canadian counterpart to the NSA, has played an active role in surveillance activities both at home and abroad, raising a host of challenging legal and policy questions. With contributions by leading experts in the field, Law, Privacy and Surveillance in Canada in the Post-Snowden Era is the right book at the right time: From the effectiveness of accountability and oversight programs to the legal issues raised by metadata collection to the privacy challenges surrounding new technologies, this book explores current issues torn from the headlines with a uniquely Canadian perspective.

    Description: A NATION ON THE LINE is an ethnographic study of the call center industry in the Philippines and of its workforce composed of young, largely college-educated Filipinos. Padios merges several lines of inquiry about Pacific transnationalism, about the role of affective labor in global markets, and about critique of Filipino exploitation by the United States through economic and military power since independence-- in order to consider how post-colonial and post-industrial changes in the Philippines’ role in global capitalism and culture are brought to bear in everyday life. Padios argues that the call center industry serves as a rich case-study for how Filipinos work within hegemonic dynamics of relational service and an understanding of American consumer culture in ways that figure Filipinos' sense of identity and aspirations at the national and individual levels.

    Description: Published in cooperation with the William P. Clements Center for Southwest Studies, Southern Methodist University. In Land of Necessity, historians and anthropologists unravel the interplay of the national and transnational and of scarcity and abundance in the region split by the 1,969-mile boundary line dividing Mexico and the United States. This richly illustrated volume, with more than 100 images including maps, photographs, and advertisements, explores the convergence of broad demographic, economic, political, cultural, and transnational developments resulting in various forms of consumer culture in the borderlands. Though its importance is uncontestable, the role of necessity in consumer culture has rarely been explored. Indeed, it has been argued that where necessity reigns, consumer culture is anemic. This volume demonstrates otherwise. In doing so, it sheds new light on the history of the U.S.-Mexico borderlands, while also opening up similar terrain for scholarly inquiry into consumer culture. The volume opens with two chapters that detail the historical trajectories of consumer culture and the borderlands. In the subsequent chapters, contributors take up subjects including smuggling, tourist districts and resorts, purchasing power, and living standards. Others address home décor, housing, urban development, and commercial real estate, while still others consider the circulation of cinematic images, contraband, used cars, and clothing. Several contributors discuss the movement of people across borders, within cities, and in retail spaces. In the two afterwords, scholars reflect on the U.S.-Mexico borderlands as a particular site of trade in labor, land, leisure, and commodities, while also musing about consumer culture as a place of complex political and economic negotiations. Through its focus on the borderlands, this volume provides valuable insight into the historical and contemporary aspects of the big “isms” shaping modern life: capitalism, nationalism, transnationalism, globalism, and, without a doubt, consumerism.

Heyman, Sarah Hill, Alexis McCrossen, Robert Perez, Laura Isabel Serna, Rachel St. John, Mauricio Tenorio-Trillo, Evan R. Ward

    Description: While many professional translators believe the ability to translate is a gift that one either has or does not have, Allison Beeby Lonsdale questions this view. In her innovative book, she demonstrates how teachers can guide their students by showing them how insights from communication theory, discourse analysis, pragmatics, and semiotics can illuminate the translation process. Using Spanish to English translation as her example, she presents the basic principles of translation through 29 teaching units, which are prefaced by objectives, tasks, and commentaries for the teacher, and through 48 task sheets, which show how to present the material to students.

    Description: Governance connotes the way an organization, an economy, or a social system co-ordinates and steers itself. Some insist that governing is strictly a top-down process guided by authority and coercion, while others emphasize that it emerges bottom-up through the workings of the free market. This book rejects these simplistic views in favour of a more distributed view of governance based on a mix of coercion, quid pro quo market exchange and reciprocity, on a division of labour among the private, public, and civic sectors, and on the co-evolution of these different integration mechanisms. This book is for both practitioners confronted with governance issues and for citizens trying to make sense of the world around them.

    Description: Border security has been high on public-policy agendas in Europe and North America since the September 11, 2001 attacks on the World Trade Centre in New York City and on the headquarters of the American military in Washington DC. Governments are now confronted with managing secure borders, a policy objective that in this era of increased free trade and globalization must compete with intense cross-border flows of people and goods. Border-security policies must enable security personnel to identify, or filter out, dangerous individuals and substances from among the millions of travelers and tons of goods that cross borders daily, particularly in large cross-border urban regions.This book addresses this gap between security needs and an understanding of borders and borderlands. Specifically, the chapters in this volume ask policy-makers to recognize that two fundamental elements define borders and borderlands: first, 〈i〉human activities〈/i〉 (the agency and agent power of individual ties and forces spanning a border), and second, the 〈i〉broader social processes〈/i〉 that frame individual action, such as market forces, government activities (law, regulations, and policies), and the regional culture and politics of a borderland.Borders emerge as the historically and geographically variable expression of human ties exercised within social structures of varying force and influence, and it is the interplay and interdependence between people's incentives to act and the surrounding structures (i.e. constructed social processes that contain and constrain individual action) that determine the effectiveness of border security policies.This book argues that the nature of borders is to be porous, which is a problem for security policy makers. It shows that when for economic, cultural, or political reasons human activities increase across a border and borderland, governments need to increase cooperation and collaboration with regard to security policies, if only to avoid implementing mismatched security policies.

    Description: In 'Dying in Full Detail' Jennifer Malkowski explores digital media's impact on one of documentary film's greatest taboos: the recording of death. Despite technological advances that allow for the easy creation and distribution of death footage, digital media often fail to live up to their promise to reveal the world in greater fidelity. Malkowski analyzes a wide range of death footage, from feature films about the terminally ill (Dying, Silverlake Life, Sick), to surreptitiously recorded suicides (The Bridge), to #BlackLivesMatter YouTube videos and their precursors. Contextualizing these recordings in the long history of attempts to capture the moment of death in American culture, Malkowski shows how digital media are unable to deliver death "in full detail," as its metaphysical truth remains beyond representation.

    Description: Transculturality is a new way of viewing culture that sees cultures not as separate islands that are easily differentiated from one another, but as connected and interacting webs of meaning and practice. The Americas in particular offer many examples of transcultural identities that do not fit easily into one national or ethnic mold: Chicanos, Franco-Ontarians, Creoles, and second and third generation immigrants. From Quebec to Argentina, this volume explores these identities which create themselves in a space between sameness and difference.
    Description: La transculturalité constitue une nouvelle façon de concevoir les cultures, c’est-àdire non plus comme des îlots distincts, mais plutôt comme des réseaux interactifs de sens et de pratiques. Ces identités transculturelles qui n’entrent pas aisément dans le seul moule d’une nation ou d’une ethnie abondent particulièrement dans les Amériques, par exemple les Chicanos, les Franco-Ontariens, les Créoles et les immigrants de deuxième et de troisième génération. De Québec à l’Argentine, cet ouvrage se penche sur ces identités qui se construisent au carrefour de la similitude et de la différence.

    Description: In the early hours of April 22, 1914, American President Woodrow Wilson sent Marines to seize the port of Veracruz in an attempt to alter the course of the Mexican Revolution. As a result, the United States seemed on the brink of war with Mexico. An international uproar ensued. The governments of Argentina, Brazil, and Chile offered to mediate a peaceful resolution to the crisis. Surprisingly, both the United States and Mexico accepted their offer and all parties agreed to meet at an international peace conference in Niagara Falls, Ontario. 〈br〉〈br〉For Canadians, the conference provided an unexpected spectacle on their doorstep, combining high diplomacy and low intrigue around the gardens and cataracts of Canada's most famous natural attraction. For the diplomats involved, it proved to be an ephemeral high point in the nascent pan-American movement. After it ended, the conference dropped out of historical memory. 〈br〉〈br〉This is the first full account of the Niagara Falls Peace Conference to be published in North America since 1914. The author carefully reconstructs what happened at Niagara Falls, examining its historical significance for Canada's relationship with the Americas. From this almost forgotten event he draws important lessons on the conduct of international mediation and the perils of middle-power diplomacy.

    Description: Cuba's first republican era (1902–1959) is principally understood in terms of its failures and discontinuities, its first three decades and the overthrow of Machado seen at best as a prologue to the "real" revolution of 1959. This book brings together scholars from North America, Cuba, and Spain to challenge this narrative, presenting republican Cuba instead as a time of meaningful engagement—socially, politically, and symbolically. Addressing a wide range of topics—civic clubs and folkloric societies, science, public health and agrarian policies, popular culture, national memory, and the intersection of race and labor—the contributors explore how a broad spectrum of Cubans embraced a political and civic culture of national self-realization. These essays recast the first republic as a time of deep continuity in processes of liberal state- and nation-building that were periodically disrupted—but also reinvigorated—by foreign intervention and profound uncertainty.

    Description: Drawing on methods and approaches from anthropology, media studies, film theory, and cultural studies, the contributors to Media, Erotics, and Transnational Asia examine how mediated eroticism and sexuality circulating across Asia and Asian diasporas both reflect and shape the social practices of their producers and consumers. The essays in this volume cover a wide geographic and thematic range, and combine rigorous textual analysis with empirical research into the production, circulation, and consumption of various forms of media. Taken together, the essays offer fresh insights into research on gender, erotics, media, and Asia transnationally conceived. Contributors. Anne Allison, Tom Boellstorff, Nicole Constable, Heather Dell, Judith Farquhar, Sarah L. Friedman, Martin F. Manalansan IV, Purnima Mankekar, Louisa Schein, Everett Yuehong Zhang.

    Description: In Musicians in Transit Matthew B. Karush examines the transnational careers of seven of the most influential Argentine musicians of the twentieth century: Afro-Argentine swing guitarist Oscar Alemán, jazz saxophonist Gato Barbieri, composer Lalo Schifrin, tango innovator Astor Piazzolla, balada singer Sandro, folksinger Mercedes Sosa, and rock musician Gustavo Santaolalla. As active participants in the globalized music business, these artists interacted with musicians and audiences in the United States, Europe, and Latin America and contended with genre distinctions, marketing conventions, and ethnic stereotypes. By responding creatively to these constraints, they made innovative music that provided Argentines with new ways of understanding their nation’s place in the world.

    Description: Citizenship is often assumed to be a clear-cut issue - either one has it or one does not. However, as the contributors to Citizenship in Question demonstrate, citizenship is not self-evident; it emerges from often obscure written records and is interpreted through ambiguous and dynamic laws. In case studies that analyze the legal barriers to citizenship rights in over twenty countries, the contributors explore how states use evidentiary requirements to create and police citizenship, often based on fictions of racial, ethnic, class, and religious differences. Whether examining the United States’ deportation of its own citizens, the selective use of DNA tests and secret results in Thailand, or laws that have stripped entire populations of citizenship, the contributors emphasize the political, psychological, and personal impact of citizenship policies.

    Description: Until recently, immigration policy was largely in the hands of a small group of bureaucrats, who strove desperately to fend off “offensive” peoples. Barbara Roberts explores these government officials, showing how they not only kept the doors closed but also managed to find a way to get rid of some of those who managed to break through their carefully guarded barriers. Robert’s important book explores a dark history with an honest and objective style.

    Description: In What’s Left of the Left, distinguished scholars of European and U.S. politics consider how center-left political parties have fared since the 1970s. They explore the left’s responses to the end of the postwar economic boom, the collapse of the Soviet Union, the erosion of traditional party politics, the expansion of market globalization, and the shift to a knowledge-based economy. Their comparative studies of center-left politics in Scandinavia, France, Germany, southern Europe, post–Cold War Central and Eastern Europe, the United Kingdom, and the United States emphasize differences in the goals of left political parties and in the political, economic, and demographic contexts in which they operate. The contributors identify and investigate the more successful center-left initiatives, scrutinizing how some conditions facilitated them, while others blocked their emergence or limited their efficacy.

    Description: 'In We Dream Together' Anne Eller breaks with dominant narratives of conflict between the Dominican Republic and Haiti by tracing the complicated history of Dominican emancipation and independence between 1822 and 1865. Eller moves beyond the small body of writing by Dominican elites that often narrates Dominican nationhood to craft inclusive, popular histories of identity, community, and freedom, summoning sources that range from trial records and consul reports to poetry and song. Rethinking Dominican relationships with their communities, the national project, and the greater Caribbean, Eller shows how popular anticolonial resistance was anchored in a rich and complex political culture. Haitians and Dominicans fostered a common commitment to Caribbean freedom, the abolition of slavery, and popular democracy, often well beyond the reach of the state.

    Description: Massive open online courses (MOOCs) are often characterized as remedies to educational disparities related to social class. Using data from 68 MOOCs offered by Harvard and MIT between 2012 and 2014, we found that course participants from the United States tended to live in more-affluent and better-educated neighborhoods than the average U.S. resident. Among those who did register for courses, students with greater socioeconomic resources were more likely to earn a certificate. Furthermore, these differences in MOOC access and completion were larger for adolescents and young adults, the traditional ages where people find on-ramps into science, technology, engineering, and mathematics (STEM) coursework and careers. Our findings raise concerns that MOOCs and similar approaches to online learning can exacerbate rather than reduce disparities in educational outcomes related to socioeconomic status.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hansen, John D -- Reich, Justin -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1245-8. doi: 10.1126/science.aab3782.

    Description: Mono-ubiquitination of Fancd2 is essential for repairing DNA interstrand cross-links (ICLs), but the underlying mechanisms are unclear. The Fan1 nuclease, also required for ICL repair, is recruited to ICLs by ubiquitinated (Ub) Fancd2. This could in principle explain how Ub-Fancd2 promotes ICL repair, but we show that recruitment of Fan1 by Ub-Fancd2 is dispensable for ICL repair. Instead, Fan1 recruitment--and activity--restrains DNA replication fork progression and prevents chromosome abnormalities from occurring when DNA replication forks stall, even in the absence of ICLs. Accordingly, Fan1 nuclease-defective knockin mice are cancer-prone. Moreover, we show that a Fan1 variant in high-risk pancreatic cancers abolishes recruitment by Ub-Fancd2 and causes genetic instability without affecting ICL repair. Therefore, Fan1 recruitment enables processing of stalled forks that is essential for genome stability and health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770513/" 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/PMC4770513/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lachaud, Christophe -- Moreno, Alberto -- Marchesi, Francesco -- Toth, Rachel -- Blow, J Julian -- Rouse, John -- WT096598MA/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):846-9. doi: 10.1126/science.aad5634.

    Description: Voltage-gated CaV1.2 channels (L-type calcium channel alpha1C subunits) are critical mediators of transcription-dependent neural plasticity. Whether these channels signal via the influx of calcium ion (Ca(2+)), voltage-dependent conformational change (VDeltaC), or a combination of the two has thus far been equivocal. We fused CaV1.2 to a ligand-gated Ca(2+)-permeable channel, enabling independent control of localized Ca(2+) and VDeltaC signals. This revealed an unexpected dual requirement: Ca(2+) must first mobilize actin-bound Ca(2+)/calmodulin-dependent protein kinase II, freeing it for subsequent VDeltaC-mediated accumulation. Neither signal alone sufficed to activate transcription. Signal order was crucial: Efficiency peaked when Ca(2+) preceded VDeltaC by 10 to 20 seconds. CaV1.2 VDeltaC synergistically augmented signaling by N-methyl-d-aspartate receptors. Furthermore, VDeltaC mistuning correlated with autistic symptoms in Timothy syndrome. Thus, nonionic VDeltaC signaling is vital to the function of CaV1.2 in synaptic and neuropsychiatric processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Boxing -- Tadross, Michael R -- Tsien, Richard W -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):863-7. doi: 10.1126/science.aad3647.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience and Physiology and New York University Neuroscience Institute, New York, NY 10016, USA. ; Department of Molecular and Cellular Physiology, Beckman Center, School of Medicine, Stanford University, Stanford, CA 94305, USA.

    Description: The recent rapid spread of Zika virus and its unexpected linkage to birth defects and an autoimmune neurological syndrome have generated worldwide concern. Zika virus is a flavivirus like the dengue, yellow fever, and West Nile viruses. We present the 3.8 angstrom resolution structure of mature Zika virus, determined by cryo-electron microscopy (cryo-EM). The structure of Zika virus is similar to other known flavivirus structures, except for the ~10 amino acids that surround the Asn(154) glycosylation site in each of the 180 envelope glycoproteins that make up the icosahedral shell. The carbohydrate moiety associated with this residue, which is recognizable in the cryo-EM electron density, may function as an attachment site of the virus to host cells. This region varies not only among Zika virus strains but also in other flaviviruses, which suggests that differences in this region may influence virus transmission and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4845755/" 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/PMC4845755/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sirohi, Devika -- Chen, Zhenguo -- Sun, Lei -- Klose, Thomas -- Pierson, Theodore C -- Rossmann, Michael G -- Kuhn, Richard J -- R01 AI073755/AI/NIAID NIH HHS/ -- R01 AI076331/AI/NIAID NIH HHS/ -- R01AI073755/AI/NIAID NIH HHS/ -- R01AI076331/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):467-70. doi: 10.1126/science.aaf5316.

    Description: The nuclear pore complex (NPC) controls the transport of macromolecules between the nucleus and cytoplasm, but its molecular architecture has thus far remained poorly defined. We biochemically reconstituted NPC core protomers and elucidated the underlying protein-protein interaction network. Flexible linker sequences, rather than interactions between the structured core scaffold nucleoporins, mediate the assembly of the inner ring complex and its attachment to the NPC coat. X-ray crystallographic analysis of these scaffold nucleoporins revealed the molecular details of their interactions with the flexible linker sequences and enabled construction of full-length atomic structures. By docking these structures into the cryoelectron tomographic reconstruction of the intact human NPC and validating their placement with our nucleoporin interactome, we built a composite structure of the NPC symmetric core that contains ~320,000 residues and accounts for ~56 megadaltons of the NPC's structured mass. Our approach provides a paradigm for the structure determination of similarly complex macromolecular assemblies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Daniel H -- Stuwe, Tobias -- Schilbach, Sandra -- Rundlet, Emily J -- Perriches, Thibaud -- Mobbs, George -- Fan, Yanbin -- Thierbach, Karsten -- Huber, Ferdinand M -- Collins, Leslie N -- Davenport, Andrew M -- Jeon, Young E -- Hoelz, Andre -- 5 T32 GM07616/GM/NIGMS NIH HHS/ -- ACB-12002/PHS HHS/ -- AGM-12006/PHS HHS/ -- R01 GM111461/GM/NIGMS NIH HHS/ -- R01-GM111461/GM/NIGMS NIH HHS/ -- T32 GM007616/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):aaf1015. doi: 10.1126/science.aaf1015.

    Description: Ebola virus disease in humans is highly lethal, with case fatality rates ranging from 25 to 90%. There is no licensed treatment or vaccine against the virus, underscoring the need for efficacious countermeasures. We ascertained that a human survivor of the 1995 Kikwit Ebola virus disease outbreak maintained circulating antibodies against the Ebola virus surface glycoprotein for more than a decade after infection. From this survivor we isolated monoclonal antibodies (mAbs) that neutralize recent and previous outbreak variants of Ebola virus and mediate antibody-dependent cell-mediated cytotoxicity in vitro. Strikingly, monotherapy with mAb114 protected macaques when given as late as 5 days after challenge. Treatment with a single human mAb suggests that a simplified therapeutic strategy for human Ebola infection may be possible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corti, Davide -- Misasi, John -- Mulangu, Sabue -- Stanley, Daphne A -- Kanekiyo, Masaru -- Wollen, Suzanne -- Ploquin, Aurelie -- Doria-Rose, Nicole A -- Staupe, Ryan P -- Bailey, Michael -- Shi, Wei -- Choe, Misook -- Marcus, Hadar -- Thompson, Emily A -- Cagigi, Alberto -- Silacci, Chiara -- Fernandez-Rodriguez, Blanca -- Perez, Laurent -- Sallusto, Federica -- Vanzetta, Fabrizia -- Agatic, Gloria -- Cameroni, Elisabetta -- Kisalu, Neville -- Gordon, Ingelise -- Ledgerwood, Julie E -- Mascola, John R -- Graham, Barney S -- Muyembe-Tamfun, Jean-Jacques -- Trefry, John C -- Lanzavecchia, Antonio -- Sullivan, Nancy J -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1339-42. doi: 10.1126/science.aad5224.

    Description: Differentiated macrophages can self-renew in tissues and expand long term in culture, but the gene regulatory mechanisms that accomplish self-renewal in the differentiated state have remained unknown. Here we show that in mice, the transcription factors MafB and c-Maf repress a macrophage-specific enhancer repertoire associated with a gene network that controls self-renewal. Single-cell analysis revealed that, in vivo, proliferating resident macrophages can access this network by transient down-regulation of Maf transcription factors. The network also controls embryonic stem cell self-renewal but is associated with distinct embryonic stem cell-specific enhancers. This indicates that distinct lineage-specific enhancer platforms regulate a shared network of genes that control self-renewal potential in both stem and mature cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soucie, Erinn L -- Weng, Ziming -- Geirsdottir, Laufey -- Molawi, Kaaweh -- Maurizio, Julien -- Fenouil, Romain -- Mossadegh-Keller, Noushine -- Gimenez, Gregory -- VanHille, Laurent -- Beniazza, Meryam -- Favret, Jeremy -- Berruyer, Carole -- Perrin, Pierre -- Hacohen, Nir -- Andrau, J-C -- Ferrier, Pierre -- Dubreuil, Patrice -- Sidow, Arend -- Sieweke, Michael H -- P01AG036695/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):aad5510. doi: 10.1126/science.aad5510.

    Description: Global climate change is a major threat to biodiversity. Large-scale analyses have generally focused on the impacts of climate change on the geographic ranges of species and on phenology, the timing of ecological phenomena. We used long-term monitoring of the abundance of breeding birds across Europe and the United States to produce, for both regions, composite population indices for two groups of species: those for which climate suitability has been either improving or declining since 1980. The ratio of these composite indices, the climate impact indicator (CII), reflects the divergent fates of species favored or disadvantaged by climate change. The trend in CII is positive and similar in the two regions. On both continents, interspecific and spatial variation in population abundance trends are well predicted by climate suitability trends.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, Philip A -- Mason, Lucy R -- Green, Rhys E -- Gregory, Richard D -- Sauer, John R -- Alison, Jamie -- Aunins, Ainars -- Brotons, Lluis -- Butchart, Stuart H M -- Campedelli, Tommaso -- Chodkiewicz, Tomasz -- Chylarecki, Przemyslaw -- Crowe, Olivia -- Elts, Jaanus -- Escandell, Virginia -- Foppen, Ruud P B -- Heldbjerg, Henning -- Herrando, Sergi -- Husby, Magne -- Jiguet, Frederic -- Lehikoinen, Aleksi -- Lindstrom, Ake -- Noble, David G -- Paquet, Jean-Yves -- Reif, Jiri -- Sattler, Thomas -- Szep, Tibor -- Teufelbauer, Norbert -- Trautmann, Sven -- van Strien, Arco J -- van Turnhout, Chris A M -- Vorisek, Petr -- Willis, Stephen G -- New York, N.Y. -- Science. 2016 Apr 1;352(6281):84-7. doi: 10.1126/science.aac4858.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Conservation Ecology Group, School of Biological and Biomedical Sciences, Durham University, South Road, Durham DH1 3LE, UK. ; Royal Society for the Protection of Birds, Centre for Conservation Science, The Lodge, Sandy, Bedfordshire SG19 2DL, UK. ; Royal Society for the Protection of Birds, Centre for Conservation Science, The Lodge, Sandy, Bedfordshire SG19 2DL, UK.

    Description: The dynamic properties of foldamers, synthetic molecules that mimic folded biomolecules, have mainly been explored in free solution. We report on the design, synthesis, and conformational behavior of photoresponsive foldamers bound in a phospholipid bilayer akin to a biological membrane phase. These molecules contain a chromophore, which can be switched between two configurations by different wavelengths of light, attached to a helical synthetic peptide that both promotes membrane insertion and communicates conformational change along its length. Light-induced structural changes in the chromophore are translated into global conformational changes, which are detected by monitoring the solid-state (19)F nuclear magnetic resonance signals of a remote fluorine-containing residue located 1 to 2 nanometers away. The behavior of the foldamers in the membrane phase is similar to that of analogous compounds in organic solvents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Poli, Matteo -- Zawodny, Wojciech -- Quinonero, Ophelie -- Lorch, Mark -- Webb, Simon J -- Clayden, Jonathan -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):575-80. doi: 10.1126/science.aad8352.

    Description: T cell-mediated destruction of insulin-producing beta cells in the pancreas causes type 1 diabetes (T1D). CD4 T cell responses play a central role in beta cell destruction, but the identity of the epitopes recognized by pathogenic CD4 T cells remains unknown. We found that diabetes-inducing CD4 T cell clones isolated from nonobese diabetic mice recognize epitopes formed by covalent cross-linking of proinsulin peptides to other peptides present in beta cell secretory granules. These hybrid insulin peptides (HIPs) are antigenic for CD4 T cells and can be detected by mass spectrometry in beta cells. CD4 T cells from the residual pancreatic islets of two organ donors who had T1D also recognize HIPs. Autoreactive T cells targeting hybrid peptides may explain how immune tolerance is broken in T1D.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Delong, Thomas -- Wiles, Timothy A -- Baker, Rocky L -- Bradley, Brenda -- Barbour, Gene -- Reisdorph, Richard -- Armstrong, Michael -- Powell, Roger L -- Reisdorph, Nichole -- Kumar, Nitesh -- Elso, Colleen M -- DeNicola, Megan -- Bottino, Rita -- Powers, Alvin C -- Harlan, David M -- Kent, Sally C -- Mannering, Stuart I -- Haskins, Kathryn -- 1K01DK094941/DK/NIDDK NIH HHS/ -- 1R01DK081166/DK/NIDDK NIH HHS/ -- 5U01DK89572/DK/NIDDK NIH HHS/ -- DK104211/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):711-4. doi: 10.1126/science.aad2791.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbiology, University of Colorado School of Medicine, Denver, Anschutz Medical Campus, Aurora, CO 80045, USA. thomas.delong@ucdenver.edu katie.haskins@ucdenver.edu. ; Department of Immunology and Microbiology, University of Colorado School of Medicine, Denver, Anschutz Medical Campus, Aurora, CO 80045, USA. ; Pharmaceutical Sciences, University of Colorado School of Medicine, Aurora, CO 80045, USA. ; Immunology and Diabetes Unit, St. Vincent's Institute of Medical Research, 9 Princes Street, Fitzroy, Victoria 3065, Australia. ; Department of Medicine, Diabetes Division, Diabetes Center of Excellence, University of Massachusetts Medical School, Worcester, MA, USA. ; Institute of Cellular Therapeutics, Allegheny-Singer Research Institute, Allegheny Health Network, Pittsburgh, PA, USA. ; Division of Diabetes, Endocrinology, and Metabolism, Department of Medicine, and Department of Molecular Physiology and Biophysics, Vanderbilt University Medical Center, Nashville, TN, USA.

    Description: Mitochondria undergo fragmentation in response to electron transport chain (ETC) poisons and mitochondrial DNA-linked disease mutations, yet how these stimuli mechanistically connect to the mitochondrial fission and fusion machinery is poorly understood. We found that the energy-sensing adenosine monophosphate (AMP)-activated protein kinase (AMPK) is genetically required for cells to undergo rapid mitochondrial fragmentation after treatment with ETC inhibitors. Moreover, direct pharmacological activation of AMPK was sufficient to rapidly promote mitochondrial fragmentation even in the absence of mitochondrial stress. A screen for substrates of AMPK identified mitochondrial fission factor (MFF), a mitochondrial outer-membrane receptor for DRP1, the cytoplasmic guanosine triphosphatase that catalyzes mitochondrial fission. Nonphosphorylatable and phosphomimetic alleles of the AMPK sites in MFF revealed that it is a key effector of AMPK-mediated mitochondrial fission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toyama, Erin Quan -- Herzig, Sebastien -- Courchet, Julien -- Lewis, Tommy L Jr -- Loson, Oliver C -- Hellberg, Kristina -- Young, Nathan P -- Chen, Hsiuchen -- Polleux, Franck -- Chan, David C -- Shaw, Reuben J -- K99 NS091526/NS/NINDS NIH HHS/ -- K99NS091526/NS/NINDS NIH HHS/ -- P01 CA120964/CA/NCI NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- R01CA172229/CA/NCI NIH HHS/ -- R01DK080425/DK/NIDDK NIH HHS/ -- R01GM062967/GM/NIGMS NIH HHS/ -- R01GM110039/GM/NIGMS NIH HHS/ -- R01NS089456/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):275-81. doi: 10.1126/science.aab4138.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biology Laboratory and Howard Hughes Medical Institute, Salk Institute for Biological Studies, La Jolla, CA 92037, USA. ; Department of Neuroscience, Zuckerman Mind Brain Behavior Institute and Kavli Institute for Brain Science, Columbia University, New York, NY 10032, USA. ; Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA. ; Molecular and Cell Biology Laboratory and Howard Hughes Medical Institute, Salk Institute for Biological Studies, La Jolla, CA 92037, USA. shaw@salk.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26816379" target="_blank"〉PubMed〈/a〉

    Description: Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faria, Nuno Rodrigues -- Azevedo, Raimunda do Socorro da Silva -- Kraemer, Moritz U G -- Souza, Renato -- Cunha, Mariana Sequetin -- Hill, Sarah C -- Theze, Julien -- Bonsall, Michael B -- Bowden, Thomas A -- Rissanen, Ilona -- Rocco, Iray Maria -- Nogueira, Juliana Silva -- Maeda, Adriana Yurika -- Vasami, Fernanda Giseli da Silva -- Macedo, Fernando Luiz de Lima -- Suzuki, Akemi -- Rodrigues, Sueli Guerreiro -- Cruz, Ana Cecilia Ribeiro -- Nunes, Bruno Tardeli -- Medeiros, Daniele Barbosa de Almeida -- Rodrigues, Daniela Sueli Guerreiro -- Nunes Queiroz, Alice Louize -- da Silva, Eliana Vieira Pinto -- Henriques, Daniele Freitas -- Travassos da Rosa, Elisabeth Salbe -- de Oliveira, Consuelo Silva -- Martins, Livia Caricio -- Vasconcelos, Helena Baldez -- Casseb, Livia Medeiros Neves -- Simith, Darlene de Brito -- Messina, Jane P -- Abade, Leandro -- Lourenco, Jose -- Carlos Junior Alcantara, Luiz -- de Lima, Maricelia Maia -- Giovanetti, Marta -- Hay, Simon I -- de Oliveira, Rodrigo Santos -- Lemos, Poliana da Silva -- de Oliveira, Layanna Freitas -- de Lima, Clayton Pereira Silva -- da Silva, Sandro Patroca -- de Vasconcelos, Janaina Mota -- Franco, Luciano -- Cardoso, Jedson Ferreira -- Vianez-Junior, Joao Lidio da Silva Goncalves -- Mir, Daiana -- Bello, Gonzalo -- Delatorre, Edson -- Khan, Kamran -- Creatore, Marisa -- Coelho, Giovanini Evelim -- de Oliveira, Wanderson Kleber -- Tesh, Robert -- Pybus, Oliver G -- Nunes, Marcio R T -- Vasconcelos, Pedro F C -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095066/Wellcome Trust/United Kingdom -- 102427/Wellcome Trust/United Kingdom -- MR/L009528/1/Medical Research Council/United Kingdom -- R24 AT 120942/AT/NCCIH NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):345-9. doi: 10.1126/science.aaf5036.

    Description: Ebola virus causes hemorrhagic fever with a high case fatality rate for which there is no approved therapy. Two human monoclonal antibodies, mAb100 and mAb114, in combination, protect nonhuman primates against all signs of Ebola virus disease, including viremia. Here, we demonstrate that mAb100 recognizes the base of the Ebola virus glycoprotein (GP) trimer, occludes access to the cathepsin-cleavage loop, and prevents the proteolytic cleavage of GP that is required for virus entry. We show that mAb114 interacts with the glycan cap and inner chalice of GP, remains associated after proteolytic removal of the glycan cap, and inhibits binding of cleaved GP to its receptor. These results define the basis of neutralization for two protective antibodies and may facilitate development of therapies and vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Misasi, John -- Gilman, Morgan S A -- Kanekiyo, Masaru -- Gui, Miao -- Cagigi, Alberto -- Mulangu, Sabue -- Corti, Davide -- Ledgerwood, Julie E -- Lanzavecchia, Antonio -- Cunningham, James -- Muyembe-Tamfun, Jean Jacques -- Baxa, Ulrich -- Graham, Barney S -- Xiang, Ye -- Sullivan, Nancy J -- McLellan, Jason S -- 5K08AI079381/AI/NIAID NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- T32GM008704/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1343-6. doi: 10.1126/science.aad6117.

    Description: With functions that range from cell envelope structure to signal transduction and transport, lipoproteins constitute 2 to 3% of bacterial genomes and play critical roles in bacterial physiology, pathogenicity, and antibiotic resistance. Lipoproteins are synthesized with a signal peptide securing them to the cytoplasmic membrane with the lipoprotein domain in the periplasm or outside the cell. Posttranslational processing requires a signal peptidase II (LspA) that removes the signal peptide. Here, we report the crystal structure of LspA from Pseudomonas aeruginosa complexed with the antimicrobial globomycin at 2.8 angstrom resolution. Mutagenesis studies identify LspA as an aspartyl peptidase. In an example of molecular mimicry, globomycin appears to inhibit by acting as a noncleavable peptide that sterically blocks the active site. This structure should inform rational antibiotic drug discovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vogeley, Lutz -- El Arnaout, Toufic -- Bailey, Jonathan -- Stansfeld, Phillip J -- Boland, Coilin -- Caffrey, Martin -- BB/I019855/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):876-80. doi: 10.1126/science.aad3747.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Medicine and School of Biochemistry and Immunology, Trinity College Dublin, Dublin, Ireland. ; Department of Biochemistry, University of Oxford, South Parks Road, Oxford, UK. ; School of Medicine and School of Biochemistry and Immunology, Trinity College Dublin, Dublin, Ireland. martin.caffrey@tcd.ie.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26912896" target="_blank"〉PubMed〈/a〉

    Description: Splicing of precursor messenger RNA is accomplished by a dynamic megacomplex known as the spliceosome. Assembly of a functional spliceosome requires a preassembled U4/U6.U5 tri-snRNP complex, which comprises the U5 small nuclear ribonucleoprotein (snRNP), the U4 and U6 small nuclear RNA (snRNA) duplex, and a number of protein factors. Here we report the three-dimensional structure of a Saccharomyces cerevisiae U4/U6.U5 tri-snRNP at an overall resolution of 3.8 angstroms by single-particle electron cryomicroscopy. The local resolution for the core regions of the tri-snRNP reaches 3.0 to 3.5 angstroms, allowing construction of a refined atomic model. Our structure contains U5 snRNA, the extensively base-paired U4/U6 snRNA, and 30 proteins including Prp8 and Snu114, which amount to 8495 amino acids and 263 nucleotides with a combined molecular mass of ~1 megadalton. The catalytic nucleotide U80 from U6 snRNA exists in an inactive conformation, stabilized by its base-pairing interactions with U4 snRNA and protected by Prp3. Pre-messenger RNA is bound in the tri-snRNP through base-pairing interactions with U6 snRNA and loop I of U5 snRNA. This structure, together with that of the spliceosome, reveals the molecular choreography of the snRNAs in the activation process of the spliceosomal ribozyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wan, Ruixue -- Yan, Chuangye -- Bai, Rui -- Wang, Lin -- Huang, Min -- Wong, Catherine C L -- Shi, Yigong -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):466-75. doi: 10.1126/science.aad6466.

    Description: The U4/U6.U5 triple small nuclear ribonucleoprotein (tri-snRNP) is a major spliceosome building block. We obtained a three-dimensional structure of the 1.8-megadalton human tri-snRNP at a resolution of 7 angstroms using single-particle cryo-electron microscopy (cryo-EM). We fit all known high-resolution structures of tri-snRNP components into the EM density map and validated them by protein cross-linking. Our model reveals how the spatial organization of Brr2 RNA helicase prevents premature U4/U6 RNA unwinding in isolated human tri-snRNPs and how the ubiquitin C-terminal hydrolase-like protein Sad1 likely tethers the helicase Brr2 to its preactivation position. Comparison of our model with cryo-EM three-dimensional structures of the Saccharomyces cerevisiae tri-snRNP and Schizosaccharomyces pombe spliceosome indicates that Brr2 undergoes a marked conformational change during spliceosome activation, and that the scaffolding protein Prp8 is also rearranged to accommodate the spliceosome's catalytic RNA network.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Agafonov, Dmitry E -- Kastner, Berthold -- Dybkov, Olexandr -- Hofele, Romina V -- Liu, Wen-Ti -- Urlaub, Henning -- Luhrmann, Reinhard -- Stark, Holger -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1416-20. doi: 10.1126/science.aad2085.

    Description: Bruns and Taylor argue that our finding of widespread distribution among Glomeromycota "virtual taxa" is undermined by the species definition applied. Although identifying appropriate species concepts and accessing taxonomically informative traits are challenges for microorganism biogeography, the virtual taxa represent a pragmatic classification that corresponds approximately to the species rank of classical Glomeromycota taxonomy, yet is applicable to environmental DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Opik, Maarja -- Davison, John -- Moora, Mari -- Partel, Meelis -- Zobel, Martin -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):826. doi: 10.1126/science.aad5495.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, University of Tartu, 40 Lai Street, 51005 Tartu, Estonia. maarja.opik@ut.ee. ; Department of Botany, University of Tartu, 40 Lai Street, 51005 Tartu, Estonia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26912890" target="_blank"〉PubMed〈/a〉

    Description: Poly(ethylene terephthalate) (PET) is used extensively worldwide in plastic products, and its accumulation in the environment has become a global concern. Because the ability to enzymatically degrade PET has been thought to be limited to a few fungal species, biodegradation is not yet a viable remediation or recycling strategy. By screening natural microbial communities exposed to PET in the environment, we isolated a novel bacterium, Ideonella sakaiensis 201-F6, that is able to use PET as its major energy and carbon source. When grown on PET, this strain produces two enzymes capable of hydrolyzing PET and the reaction intermediate, mono(2-hydroxyethyl) terephthalic acid. Both enzymes are required to enzymatically convert PET efficiently into its two environmentally benign monomers, terephthalic acid and ethylene glycol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Shosuke -- Hiraga, Kazumi -- Takehana, Toshihiko -- Taniguchi, Ikuo -- Yamaji, Hironao -- Maeda, Yasuhito -- Toyohara, Kiyotsuna -- Miyamoto, Kenji -- Kimura, Yoshiharu -- Oda, Kohei -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1196-9. doi: 10.1126/science.aad6359.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Biology, Faculty of Textile Science, Kyoto Institute of Technology, Matsugasaki, Sakyo-ku, Kyoto 606-8585, Japan.

    Description: SH3 and multiple ankyrin repeat domains 3 (SHANK3) haploinsufficiency is causative for the neurological features of Phelan-McDermid syndrome (PMDS), including a high risk of autism spectrum disorder (ASD). We used unbiased, quantitative proteomics to identify changes in the phosphoproteome of Shank3-deficient neurons. Down-regulation of protein kinase B (PKB/Akt)-mammalian target of rapamycin complex 1 (mTORC1) signaling resulted from enhanced phosphorylation and activation of serine/threonine protein phosphatase 2A (PP2A) regulatory subunit, B56beta, due to increased steady-state levels of its kinase, Cdc2-like kinase 2 (CLK2). Pharmacological and genetic activation of Akt or inhibition of CLK2 relieved synaptic deficits in Shank3-deficient and PMDS patient-derived neurons. CLK2 inhibition also restored normal sociability in a Shank3-deficient mouse model. Our study thereby provides a novel mechanistic and potentially therapeutic understanding of deregulated signaling downstream of Shank3 deficiency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bidinosti, Michael -- Botta, Paolo -- Kruttner, Sebastian -- Proenca, Catia C -- Stoehr, Natacha -- Bernhard, Mario -- Fruh, Isabelle -- Mueller, Matthias -- Bonenfant, Debora -- Voshol, Hans -- Carbone, Walter -- Neal, Sarah J -- McTighe, Stephanie M -- Roma, Guglielmo -- Dolmetsch, Ricardo E -- Porter, Jeffrey A -- Caroni, Pico -- Bouwmeester, Tewis -- Luthi, Andreas -- Galimberti, Ivan -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1199-203. doi: 10.1126/science.aad5487.

    Description: Bacterial adaptive immunity and genome engineering involving the CRISPR (clustered regularly interspaced short palindromic repeats)-associated (Cas) protein Cas9 begin with RNA-guided DNA unwinding to form an RNA-DNA hybrid and a displaced DNA strand inside the protein. The role of this R-loop structure in positioning each DNA strand for cleavage by the two Cas9 nuclease domains is unknown. We determine molecular structures of the catalytically active Streptococcus pyogenes Cas9 R-loop that show the displaced DNA strand located near the RuvC nuclease domain active site. These protein-DNA interactions, in turn, position the HNH nuclease domain adjacent to the target DNA strand cleavage site in a conformation essential for concerted DNA cutting. Cas9 bends the DNA helix by 30 degrees , providing the structural distortion needed for R-loop formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Fuguo -- Taylor, David W -- Chen, Janice S -- Kornfeld, Jack E -- Zhou, Kaihong -- Thompson, Aubri J -- Nogales, Eva -- Doudna, Jennifer A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):867-71. doi: 10.1126/science.aad8282.

    Description: Induction of broadly neutralizing antibodies (bnAbs) is a major HIV vaccine goal. Germline-targeting immunogens aim to initiate bnAb induction by activating bnAb germline precursor B cells. Critical unmet challenges are to determine whether bnAb precursor naive B cells bind germline-targeting immunogens and occur at sufficient frequency in humans for reliable vaccine responses. Using deep mutational scanning and multitarget optimization, we developed a germline-targeting immunogen (eOD-GT8) for diverse VRC01-class bnAbs. We then used the immunogen to isolate VRC01-class precursor naive B cells from HIV-uninfected donors. Frequencies of true VRC01-class precursors, their structures, and their eOD-GT8 affinities support this immunogen as a candidate human vaccine prime. These methods could be applied to germline targeting for other classes of HIV bnAbs and for Abs to other pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4872700/" 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/PMC4872700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jardine, Joseph G -- Kulp, Daniel W -- Havenar-Daughton, Colin -- Sarkar, Anita -- Briney, Bryan -- Sok, Devin -- Sesterhenn, Fabian -- Ereno-Orbea, June -- Kalyuzhniy, Oleksandr -- Deresa, Isaiah -- Hu, Xiaozhen -- Spencer, Skye -- Jones, Meaghan -- Georgeson, Erik -- Adachi, Yumiko -- Kubitz, Michael -- deCamp, Allan C -- Julien, Jean-Philippe -- Wilson, Ian A -- Burton, Dennis R -- Crotty, Shane -- Schief, William R -- P01 AI094419/AI/NIAID NIH HHS/ -- P01 AI110657/AI/NIAID NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1458-63. doi: 10.1126/science.aad9195.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbial Science, The Scripps Research Institute, La Jolla, CA 92037, USA.

    Description: Recent studies have implicated long noncoding RNAs (lncRNAs) as regulators of many important biological processes. Here we report on the identification and characterization of a lncRNA, lnc13, that harbors a celiac disease-associated haplotype block and represses expression of certain inflammatory genes under homeostatic conditions. Lnc13 regulates gene expression by binding to hnRNPD, a member of a family of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). Upon stimulation, lnc13 levels are reduced, thereby allowing increased expression of the repressed genes. Lnc13 levels are significantly decreased in small intestinal biopsy samples from patients with celiac disease, which suggests that down-regulation of lnc13 may contribute to the inflammation seen in this disease. Furthermore, the lnc13 disease-associated variant binds hnRNPD less efficiently than its wild-type counterpart, thus helping to explain how these single-nucleotide polymorphisms contribute to celiac disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castellanos-Rubio, Ainara -- Fernandez-Jimenez, Nora -- Kratchmarov, Radomir -- Luo, Xiaobing -- Bhagat, Govind -- Green, Peter H R -- Schneider, Robert -- Kiledjian, Megerditch -- Bilbao, Jose Ramon -- Ghosh, Sankar -- R01-AI093985/AI/NIAID NIH HHS/ -- R01-DK102180/DK/NIDDK NIH HHS/ -- R01-GM067005/GM/NIGMS NIH HHS/ -- R37-AI33443/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 1;352(6281):91-5. doi: 10.1126/science.aad0467.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Columbia University, College of Physicians and Surgeons, New York, NY 10032, USA. ; Department of Genetics, Physical Anthropology, and Animal Physiology, University of the Basque Country (UPV-EHU), BioCruces Research Institute, Leioa 48940, Basque Country, Spain. ; Department of Pathology and Cell Biology, Columbia University, College of Physicians and Surgeons, New York, NY 10032, USA. ; Center for Celiac Disease, Department of Medicine, Columbia University, College of Physicians and Surgeons, New York, NY 10032, USA.

    Description: The oxidation of methane with sulfate is an important microbial metabolism in the global carbon cycle. In marine methane seeps, this process is mediated by consortia of anaerobic methanotrophic archaea (ANME) that live in syntrophy with sulfate-reducing bacteria (SRB). The underlying interdependencies within this uncultured symbiotic partnership are poorly understood. We used a combination of rate measurements and single-cell stable isotope probing to demonstrate that ANME in deep-sea sediments can be catabolically and anabolically decoupled from their syntrophic SRB partners using soluble artificial oxidants. The ANME still sustain high rates of methane oxidation in the absence of sulfate as the terminal oxidant, lending support to the hypothesis that interspecies extracellular electron transfer is the syntrophic mechanism for the anaerobic oxidation of methane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheller, Silvan -- Yu, Hang -- Chadwick, Grayson L -- McGlynn, Shawn E -- Orphan, Victoria J -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):703-7. doi: 10.1126/science.aad7154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Geological and Planetary Sciences, 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/26912857" target="_blank"〉PubMed〈/a〉

    Description: Seagrasses colonized the sea on at least three independent occasions to form the basis of one of the most productive and widespread coastal ecosystems on the planet. Here we report the genome of Zostera marina (L.), the first, to our knowledge, marine angiosperm to be fully sequenced. This reveals unique insights into the genomic losses and gains involved in achieving the structural and physiological adaptations required for its marine lifestyle, arguably the most severe habitat shift ever accomplished by flowering plants. Key angiosperm innovations that were lost include the entire repertoire of stomatal genes, genes involved in the synthesis of terpenoids and ethylene signalling, and genes for ultraviolet protection and phytochromes for far-red sensing. Seagrasses have also regained functions enabling them to adjust to full salinity. Their cell walls contain all of the polysaccharides typical of land plants, but also contain polyanionic, low-methylated pectins and sulfated galactans, a feature shared with the cell walls of all macroalgae and that is important for ion homoeostasis, nutrient uptake and O2/CO2 exchange through leaf epidermal cells. The Z. marina genome resource will markedly advance a wide range of functional ecological studies from adaptation of marine ecosystems under climate warming, to unravelling the mechanisms of osmoregulation under high salinities that may further inform our understanding of the evolution of salt tolerance in crop plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Jeanine L -- Rouze, Pierre -- Verhelst, Bram -- Lin, Yao-Cheng -- Bayer, Till -- Collen, Jonas -- Dattolo, Emanuela -- De Paoli, Emanuele -- Dittami, Simon -- Maumus, Florian -- Michel, Gurvan -- Kersting, Anna -- Lauritano, Chiara -- Lohaus, Rolf -- Topel, Mats -- Tonon, Thierry -- Vanneste, Kevin -- Amirebrahimi, Mojgan -- Brakel, Janina -- Bostrom, Christoffer -- Chovatia, Mansi -- Grimwood, Jane -- Jenkins, Jerry W -- Jueterbock, Alexander -- Mraz, Amy -- Stam, Wytze T -- Tice, Hope -- Bornberg-Bauer, Erich -- Green, Pamela J -- Pearson, Gareth A -- Procaccini, Gabriele -- Duarte, Carlos M -- Schmutz, Jeremy -- Reusch, Thorsten B H -- Van de Peer, Yves -- England -- Nature. 2016 Feb 18;530(7590):331-5. doi: 10.1038/nature16548.

    Description: Catalysis in biology is restricted to RNA (ribozymes) and protein enzymes, but synthetic biomolecular catalysts can also be made of DNA (deoxyribozymes) or synthetic genetic polymers. In vitro selection from synthetic random DNA libraries identified DNA catalysts for various chemical reactions beyond RNA backbone cleavage. DNA-catalysed reactions include RNA and DNA ligation in various topologies, hydrolytic cleavage and photorepair of DNA, as well as reactions of peptides and small molecules. In spite of comprehensive biochemical studies of DNA catalysts for two decades, fundamental mechanistic understanding of their function is lacking in the absence of three-dimensional models at atomic resolution. Early attempts to solve the crystal structure of an RNA-cleaving deoxyribozyme resulted in a catalytically irrelevant nucleic acid fold. Here we report the crystal structure of the RNA-ligating deoxyribozyme 9DB1 (ref. 14) at 2.8 A resolution. The structure captures the ligation reaction in the post-catalytic state, revealing a compact folding unit stabilized by numerous tertiary interactions, and an unanticipated organization of the catalytic centre. Structure-guided mutagenesis provided insights into the basis for regioselectivity of the ligation reaction and allowed remarkable manipulation of substrate recognition and reaction rate. Moreover, the structure highlights how the specific properties of deoxyribose are reflected in the backbone conformation of the DNA catalyst, in support of its intricate three-dimensional organization. The structural principles underlying the catalytic ability of DNA elucidate differences and similarities in DNA versus RNA catalysts, which is relevant for comprehending the privileged position of folded RNA in the prebiotic world and in current organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponce-Salvatierra, Almudena -- Wawrzyniak-Turek, Katarzyna -- Steuerwald, Ulrich -- Hobartner, Claudia -- Pena, Vladimir -- England -- Nature. 2016 Jan 14;529(7585):231-4. doi: 10.1038/nature16471.

    Description: The terrestrial biosphere can release or absorb the greenhouse gases, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), and therefore has an important role in regulating atmospheric composition and climate. Anthropogenic activities such as land-use change, agriculture and waste management have altered terrestrial biogenic greenhouse gas fluxes, and the resulting increases in methane and nitrous oxide emissions in particular can contribute to climate change. The terrestrial biogenic fluxes of individual greenhouse gases have been studied extensively, but the net biogenic greenhouse gas balance resulting from anthropogenic activities and its effect on the climate system remains uncertain. Here we use bottom-up (inventory, statistical extrapolation of local flux measurements, and process-based modelling) and top-down (atmospheric inversions) approaches to quantify the global net biogenic greenhouse gas balance between 1981 and 2010 resulting from anthropogenic activities and its effect on the climate system. We find that the cumulative warming capacity of concurrent biogenic methane and nitrous oxide emissions is a factor of about two larger than the cooling effect resulting from the global land carbon dioxide uptake from 2001 to 2010. This results in a net positive cumulative impact of the three greenhouse gases on the planetary energy budget, with a best estimate (in petagrams of CO2 equivalent per year) of 3.9 +/- 3.8 (top down) and 5.4 +/- 4.8 (bottom up) based on the GWP100 metric (global warming potential on a 100-year time horizon). Our findings suggest that a reduction in agricultural methane and nitrous oxide emissions, particularly in Southern Asia, may help mitigate climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tian, Hanqin -- Lu, Chaoqun -- Ciais, Philippe -- Michalak, Anna M -- Canadell, Josep G -- Saikawa, Eri -- Huntzinger, Deborah N -- Gurney, Kevin R -- Sitch, Stephen -- Zhang, Bowen -- Yang, Jia -- Bousquet, Philippe -- Bruhwiler, Lori -- Chen, Guangsheng -- Dlugokencky, Edward -- Friedlingstein, Pierre -- Melillo, Jerry -- Pan, Shufen -- Poulter, Benjamin -- Prinn, Ronald -- Saunois, Marielle -- Schwalm, Christopher R -- Wofsy, Steven C -- England -- Nature. 2016 Mar 10;531(7593):225-8. doi: 10.1038/nature16946.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉International Center for Climate and Global Change Research, School of Forestry and Wildlife Sciences, Auburn University, Auburn, Alabama 36849, USA. ; Department of Ecology, Evolution, and Organismal Biology, Iowa State University, Iowa 50011, USA. ; Laboratoire des Sciences du Climat et de l'Environnement, 91191 Gif sur Yvette, France. ; Department of Global Ecology, Carnegie Institution for Science, Stanford, California 94305, USA. ; Global Carbon Project, CSIRO Oceans and Atmosphere Research, GPO Box 3023, Canberra, Australian Capital Territory 2601, Australia. ; Department of Environmental Sciences, Emory University, Atlanta, Georgia 30322, USA. ; School of Earth Sciences and Environmental Sustainability, Northern Arizona University, Flagstaff, Arizona 86011, USA. ; School of Life Sciences, Arizona State University, Tempe, Arizona 85287, USA. ; College of Life and Environmental Sciences, University of Exeter, Exeter EX4 4RJ, UK. ; NOAA Earth System Research Laboratory, Global Monitoring Division, Boulder, Colorado 80305, USA. ; Environmental Science Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831, USA. ; College of Engineering, Mathematics and Physical Sciences, University of Exeter, Exeter EX4 4QF, UK. ; The Ecosystems Center, Marine Biological Laboratory, Woods Hole, Massachusetts 02543, USA. ; Institute of Ecosystems and Department of Ecology, Montana State University, Bozeman, Montana 59717, USA. ; Center for Global Change Science, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA. ; Woods Hole Research Center, Falmouth, Massachusetts 02540, USA. ; Department of Earth and Planetary Science, Harvard University, 29 Oxford Street, Cambridge, Massachusetts 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26961656" target="_blank"〉PubMed〈/a〉

    Description: The biological carbon pump is the process by which CO2 is transformed to organic carbon via photosynthesis, exported through sinking particles, and finally sequestered in the deep ocean. While the intensity of the pump correlates with plankton community composition, the underlying ecosystem structure driving the process remains largely uncharacterized. Here we use environmental and metagenomic data gathered during the Tara Oceans expedition to improve our understanding of carbon export in the oligotrophic ocean. We show that specific plankton communities, from the surface and deep chlorophyll maximum, correlate with carbon export at 150 m and highlight unexpected taxa such as Radiolaria and alveolate parasites, as well as Synechococcus and their phages, as lineages most strongly associated with carbon export in the subtropical, nutrient-depleted, oligotrophic ocean. Additionally, we show that the relative abundance of a few bacterial and viral genes can predict a significant fraction of the variability in carbon export in these regions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4851848/" 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/PMC4851848/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guidi, Lionel -- Chaffron, Samuel -- Bittner, Lucie -- Eveillard, Damien -- Larhlimi, Abdelhalim -- Roux, Simon -- Darzi, Youssef -- Audic, Stephane -- Berline, Leo -- Brum, Jennifer R -- Coelho, Luis Pedro -- Espinoza, Julio Cesar Ignacio -- Malviya, Shruti -- Sunagawa, Shinichi -- Dimier, Celine -- Kandels-Lewis, Stefanie -- Picheral, Marc -- Poulain, Julie -- Searson, Sarah -- Tara Oceans Consortium Coordinators -- Stemmann, Lars -- Not, Fabrice -- Hingamp, Pascal -- Speich, Sabrina -- Follows, Mick -- Karp-Boss, Lee -- Boss, Emmanuel -- Ogata, Hiroyuki -- Pesant, Stephane -- Weissenbach, Jean -- Wincker, Patrick -- Acinas, Silvia G -- Bork, Peer -- de Vargas, Colomban -- Iudicone, Daniele -- Sullivan, Matthew B -- Raes, Jeroen -- Karsenti, Eric -- Bowler, Chris -- Gorsky, Gabriel -- England -- Nature. 2016 Apr 28;532(7600):465-70. doi: 10.1038/nature16942.

    Description: Plant respiration results in an annual flux of carbon dioxide (CO2) to the atmosphere that is six times as large as that due to the emissions from fossil fuel burning, so changes in either will impact future climate. As plant respiration responds positively to temperature, a warming world may result in additional respiratory CO2 release, and hence further atmospheric warming. Plant respiration can acclimate to altered temperatures, however, weakening the positive feedback of plant respiration to rising global air temperature, but a lack of evidence on long-term (weeks to years) acclimation to climate warming in field settings currently hinders realistic predictions of respiratory release of CO2 under future climatic conditions. Here we demonstrate strong acclimation of leaf respiration to both experimental warming and seasonal temperature variation for juveniles of ten North American tree species growing for several years in forest conditions. Plants grown and measured at 3.4 degrees C above ambient temperature increased leaf respiration by an average of 5% compared to plants grown and measured at ambient temperature; without acclimation, these increases would have been 23%. Thus, acclimation eliminated 80% of the expected increase in leaf respiration of non-acclimated plants. Acclimation of leaf respiration per degree temperature change was similar for experimental warming and seasonal temperature variation. Moreover, the observed increase in leaf respiration per degree increase in temperature was less than half as large as the average reported for previous studies, which were conducted largely over shorter time scales in laboratory settings. If such dampening effects of leaf thermal acclimation occur generally, the increase in respiration rates of terrestrial plants in response to climate warming may be less than predicted, and thus may not raise atmospheric CO2 concentrations as much as anticipated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, Peter B -- Sendall, Kerrie M -- Stefanski, Artur -- Wei, Xiaorong -- Rich, Roy L -- Montgomery, Rebecca A -- England -- Nature. 2016 Mar 31;531(7596):633-6. doi: 10.1038/nature17142.

    Description: The tremendous pandemic potential of coronaviruses was demonstrated twice in the past few decades by two global outbreaks of deadly pneumonia. Entry of coronaviruses into cells is mediated by the transmembrane spike glycoprotein S, which forms a trimer carrying receptor-binding and membrane fusion functions. S also contains the principal antigenic determinants and is the target of neutralizing antibodies. Here we present the structure of a mouse coronavirus S trimer ectodomain determined at 4.0 A resolution by single particle cryo-electron microscopy. It reveals the metastable pre-fusion architecture of S and highlights key interactions stabilizing it. The structure shares a common core with paramyxovirus F proteins, implicating mechanistic similarities and an evolutionary connection between these viral fusion proteins. The accessibility of the highly conserved fusion peptide at the periphery of the trimer indicates potential vaccinology strategies to elicit broadly neutralizing antibodies against coronaviruses. Finally, comparison with crystal structures of human coronavirus S domains allows rationalization of the molecular basis for species specificity based on the use of spatially contiguous but distinct domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walls, Alexandra C -- Tortorici, M Alejandra -- Bosch, Berend-Jan -- Frenz, Brandon -- Rottier, Peter J M -- DiMaio, Frank -- Rey, Felix A -- Veesler, David -- GM103310/GM/NIGMS NIH HHS/ -- T32GM008268/GM/NIGMS NIH HHS/ -- England -- Nature. 2016 Mar 3;531(7592):114-7. doi: 10.1038/nature16988.

    Description: (beta-)Arrestins are important regulators of G-protein-coupled receptors (GPCRs). They bind to active, phosphorylated GPCRs and thereby shut off 'classical' signalling to G proteins, trigger internalization of GPCRs via interaction with the clathrin machinery and mediate signalling via 'non-classical' pathways. In addition to two visual arrestins that bind to rod and cone photoreceptors (termed arrestin1 and arrestin4), there are only two (non-visual) beta-arrestin proteins (beta-arrestin1 and beta-arrestin2, also termed arrestin2 and arrestin3), which regulate hundreds of different (non-visual) GPCRs. Binding of these proteins to GPCRs usually requires the active form of the receptors plus their phosphorylation by G-protein-coupled receptor kinases (GRKs). The binding of receptors or their carboxy terminus as well as certain truncations induce active conformations of (beta-)arrestins that have recently been solved by X-ray crystallography. Here we investigate both the interaction of beta-arrestin with GPCRs, and the beta-arrestin conformational changes in real time and in living human cells, using a series of fluorescence resonance energy transfer (FRET)-based beta-arrestin2 biosensors. We observe receptor-specific patterns of conformational changes in beta-arrestin2 that occur rapidly after the receptor-beta-arrestin2 interaction. After agonist removal, these changes persist for longer than the direct receptor interaction. Our data indicate a rapid, receptor-type-specific, two-step binding and activation process between GPCRs and beta-arrestins. They further indicate that beta-arrestins remain active after dissociation from receptors, allowing them to remain at the cell surface and presumably signal independently. Thus, GPCRs trigger a rapid, receptor-specific activation/deactivation cycle of beta-arrestins, which permits their active signalling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nuber, Susanne -- Zabel, Ulrike -- Lorenz, Kristina -- Nuber, Andreas -- Milligan, Graeme -- Tobin, Andrew B -- Lohse, Martin J -- Hoffmann, Carsten -- 1 R01 DA038882/DA/NIDA NIH HHS/ -- BB/K019864/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2016 Mar 31;531(7596):661-4. doi: 10.1038/nature17198.

    Description: The most recent Ebola virus outbreak in West Africa, which was unprecedented in the number of cases and fatalities, geographic distribution, and number of nations affected, highlights the need for safe, effective, and readily available antiviral agents for treatment and prevention of acute Ebola virus (EBOV) disease (EVD) or sequelae. No antiviral therapeutics have yet received regulatory approval or demonstrated clinical efficacy. Here we report the discovery of a novel small molecule GS-5734, a monophosphoramidate prodrug of an adenosine analogue, with antiviral activity against EBOV. GS-5734 exhibits antiviral activity against multiple variants of EBOV and other filoviruses in cell-based assays. The pharmacologically active nucleoside triphosphate (NTP) is efficiently formed in multiple human cell types incubated with GS-5734 in vitro, and the NTP acts as an alternative substrate and RNA-chain terminator in primer-extension assays using a surrogate respiratory syncytial virus RNA polymerase. Intravenous administration of GS-5734 to nonhuman primates resulted in persistent NTP levels in peripheral blood mononuclear cells (half-life, 14 h) and distribution to sanctuary sites for viral replication including testes, eyes, and brain. In a rhesus monkey model of EVD, once-daily intravenous administration of 10 mg kg(-1) GS-5734 for 12 days resulted in profound suppression of EBOV replication and protected 100% of EBOV-infected animals against lethal disease, ameliorating clinical disease signs and pathophysiological markers, even when treatments were initiated three days after virus exposure when systemic viral RNA was detected in two out of six treated animals. These results show the first substantive post-exposure protection by a small-molecule antiviral compound against EBOV in nonhuman primates. The broad-spectrum antiviral activity of GS-5734 in vitro against other pathogenic RNA viruses, including filoviruses, arenaviruses, and coronaviruses, suggests the potential for wider medical use. GS-5734 is amenable to large-scale manufacturing, and clinical studies investigating the drug safety and pharmacokinetics are ongoing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Travis K -- Jordan, Robert -- Lo, Michael K -- Ray, Adrian S -- Mackman, Richard L -- Soloveva, Veronica -- Siegel, Dustin -- Perron, Michel -- Bannister, Roy -- Hui, Hon C -- Larson, Nate -- Strickley, Robert -- Wells, Jay -- Stuthman, Kelly S -- Van Tongeren, Sean A -- Garza, Nicole L -- Donnelly, Ginger -- Shurtleff, Amy C -- Retterer, Cary J -- Gharaibeh, Dima -- Zamani, Rouzbeh -- Kenny, Tara -- Eaton, Brett P -- Grimes, Elizabeth -- Welch, Lisa S -- Gomba, Laura -- Wilhelmsen, Catherine L -- Nichols, Donald K -- Nuss, Jonathan E -- Nagle, Elyse R -- Kugelman, Jeffrey R -- Palacios, Gustavo -- Doerffler, Edward -- Neville, Sean -- Carra, Ernest -- Clarke, Michael O -- Zhang, Lijun -- Lew, Willard -- Ross, Bruce -- Wang, Queenie -- Chun, Kwon -- Wolfe, Lydia -- Babusis, Darius -- Park, Yeojin -- Stray, Kirsten M -- Trancheva, Iva -- Feng, Joy Y -- Barauskas, Ona -- Xu, Yili -- Wong, Pamela -- Braun, Molly R -- Flint, Mike -- McMullan, Laura K -- Chen, Shan-Shan -- Fearns, Rachel -- Swaminathan, Swami -- Mayers, Douglas L -- Spiropoulou, Christina F -- Lee, William A -- Nichol, Stuart T -- Cihlar, Tomas -- Bavari, Sina -- R01 AI113321/AI/NIAID NIH HHS/ -- R01AI113321/AI/NIAID NIH HHS/ -- England -- Nature. 2016 Mar 17;531(7594):381-5. doi: 10.1038/nature17180.

    Description: Arrestins are cytosolic proteins that regulate G-protein-coupled receptor (GPCR) desensitization, internalization, trafficking and signalling. Arrestin recruitment uncouples GPCRs from heterotrimeric G proteins, and targets the proteins for internalization via clathrin-coated pits. Arrestins also function as ligand-regulated scaffolds that recruit multiple non-G-protein effectors into GPCR-based 'signalsomes'. Although the dominant function(s) of arrestins vary between receptors, the mechanism whereby different GPCRs specify these divergent functions is unclear. Using a panel of intramolecular fluorescein arsenical hairpin (FlAsH) bioluminescence resonance energy transfer (BRET) reporters to monitor conformational changes in beta-arrestin2, here we show that GPCRs impose distinctive arrestin 'conformational signatures' that reflect the stability of the receptor-arrestin complex and role of beta-arrestin2 in activating or dampening downstream signalling events. The predictive value of these signatures extends to structurally distinct ligands activating the same GPCR, such that the innate properties of the ligand are reflected as changes in beta-arrestin2 conformation. Our findings demonstrate that information about ligand-receptor conformation is encoded within the population average beta-arrestin2 conformation, and provide insight into how different GPCRs can use a common effector for different purposes. This approach may have application in the characterization and development of functionally selective GPCR ligands and in identifying factors that dictate arrestin conformation and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Mi-Hye -- Appleton, Kathryn M -- Strungs, Erik G -- Kwon, Joshua Y -- Morinelli, Thomas A -- Peterson, Yuri K -- Laporte, Stephane A -- Luttrell, Louis M -- DK055524/DK/NIDDK NIH HHS/ -- GM095497/GM/NIGMS NIH HHS/ -- MOP-74603/Canadian Institutes of Health Research/Canada -- R01 DK055524/DK/NIDDK NIH HHS/ -- R01 GM095497/GM/NIGMS NIH HHS/ -- RR027777/RR/NCRR NIH HHS/ -- S10 RR027777/RR/NCRR NIH HHS/ -- England -- Nature. 2016 Mar 31;531(7596):665-8. doi: 10.1038/nature17154.

    Description: As climate change unfolds, weather systems in the United States have been shifting in patterns that vary across regions and seasons. Climate science research typically assesses these changes by examining individual weather indicators, such as temperature or precipitation, in isolation, and averaging their values across the spatial surface. As a result, little is known about population exposure to changes in weather and how people experience and evaluate these changes considered together. Here we show that in the United States from 1974 to 2013, the weather conditions experienced by the vast majority of the population improved. Using previous research on how weather affects local population growth to develop an index of people's weather preferences, we find that 80% of Americans live in counties that are experiencing more pleasant weather than they did four decades ago. Virtually all Americans are now experiencing the much milder winters that they typically prefer, and these mild winters have not been offset by markedly more uncomfortable summers or other negative changes. Climate change models predict that this trend is temporary, however, because US summers will eventually warm more than winters. Under a scenario in which greenhouse gas emissions proceed at an unabated rate (Representative Concentration Pathway 8.5), we estimate that 88% of the US public will experience weather at the end of the century that is less preferable than weather in the recent past. Our results have implications for the public's understanding of the climate change problem, which is shaped in part by experiences with local weather. Whereas weather patterns in recent decades have served as a poor source of motivation for Americans to demand a policy response to climate change, public concern may rise once people's everyday experiences of climate change effects start to become less pleasant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Egan, Patrick J -- Mullin, Megan -- England -- Nature. 2016 Apr 21;532(7599):357-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/27127821" target="_blank"〉PubMed〈/a〉
