    Description: How much of something do we need to keep people safe and well? This question is frequently asked by those working in risk management. Across diverse sectors from flood protection to health care, practitioners assess risk as the product of the impact of a given event and the probability of its occurrence. Although these estimates are often uncertain, policy-makers must ultimately make spending decisions aimed at averting these risks, because the costs of inaction to society can be substantial. Biodiversity loss is a similarly critical, yet uncertain, issue. On page 288 of this issue, Newbold et al. (1) quantify global biodiversity losses, providing much-needed information on the encroachment of proposed “safe limits.” Author: Tom H. Oliver

    Description: Butterflies are better documented and monitored worldwide than any other nonpest taxon of insects (1). In the United Kingdom alone, volunteer recorders have sampled more than 750,000 km of repeat transects since 1976, equivalent to walking to the Moon and back counting butterflies (2). Such programs are revealing regional extinctions and population declines that began before 1900 (3, 4). In a recent study, Habel et al. report a similar story based on inventories of butterflies and burnet moths since 1840 in a protected area in Bavaria, Germany (5). The results reveal severe species losses: Scarce, specialized butterflies have largely disappeared, leaving ecosystems dominated by common generalist ones. Similar trends are seen across Europe (6) and beyond, with protected areas failing to conserve many species for which they were once famed. Author: Jeremy A. Thomas

    Description: On 21 October 2013, the Italian phytosanitary service notified the European Commission (EC) that the plant pathogen Xylella fastidiosa had been detected in olive trees near Gallipoli, a tourist destination in Italy's southern region of Apulia (1). This xylem-limited bacterium is spread by insect vectors and causes disease in crops such as grapevines, citrus, coffee, and almond; various ornamentals; and trees such as oaks, elms, and sycamores. Because of the risks of X. fastidiosa being introduced, established, and spread throughout Europe, this species is a regulated quarantine pest. Yet, X. fastidiosa has been left unchecked and has marched northward, leaving destruction in its wake (see the photo) (2). The establishment of X. fastidiosa in Italy has been an agricultural, environmental, political, and cultural disaster. Author: Rodrigo P. P. Almeida

    Description: Recent dives into Colombia's Cartagena Bay have revealed an unusually resilient coral reef thriving in the polluted waters. But the reef faces a threat: an end to Colombia's decades-long guerrilla war. The government is on the verge of inking a peace deal with its main adversary, the Revolutionary Armed Forces of Colombia, or FARC. Experts expect peace to lead to a development boom, threatening ecosystems all over the country with deforestation and runoff. A new shipping lane is planned for Cartagena Bay, and construction will mean dredging right through the reef. Researchers believe studying the reef's resiliency could help struggling corals around the world and are racing to collect samples before it's too late. Author: Lizzie Wade

    Description: Early Victorian naturalists marveled at the profusion of diversity they encountered as they traveled from temperate to tropical latitudes. The inverse relationship between latitude and species richness that these naturalists first observed is now referred to as the latitudinal diversity gradient. Various ecological and evolutionary explanations have been proposed for the latitudinal diversity gradient. Of these, perhaps none are more relevant to contemporary conservation issues than Janzen's hypothesis of latitudinal differences in species' climatic tolerances and thermal selectivity (1). On page 1437 of this issue, Chan et al. (2) advance Janzen's early theories by elucidating some of the potential selective pressures imposed by climate and climate variability. Authors: Timothy M. Perez, James T. Stroud, Kenneth J. Feeley

    Description: In 1492, Columbus encountered frigate birds while en route to the New World and noted that the bird “does not alight on the sea nor depart from land 20 leagues” (1). Columbus observed correctly that frigate birds do not land on the sea, but he severely underestimated how far some frigate birds fly from land. On page 74 of this issue, Weimerskirch et al. (2) show that great frigate birds (Fregata minor) reduce transit costs by riding strong thermal updrafts beneath or inside cumulus clouds and then gliding long distances to another thermal, searching for food along the way. By exploiting cumulus clouds and trade winds in the Indian Ocean, the birds forage around the doldrums, a largely windless zone. Authors: Raymond B. Huey, Curtis Deutsch

    Description: Climate change affects wild plant species across their geographical ranges. Studies at the margins of species' ranges reveal upslope expansion, low-elevation range contraction, and, in some cases, a lack of geographic response to climate change (1). However, all populations, including those in the core of species' ranges, are subject to climate-driven natural selection that promotes adaptation to a warmer world (2). Theoretical models show that coupled spatial and temporal responses of populations can mediate the negative effects of climate change (3, 4), but it remains unclear whether these processes can occur fast enough to rescue populations from extinction (5). On page 69 of this issue, Petry et al. (6) report rapid spatial and temporal change in plant sex ratios in response to changing climatic conditions. These changes could facilitate geographic range shifts in the montane perennial herb valerian (Valeriana edulis). Authors: Julie R. Etterson, Susan J. Mazer

    Description: New rules governing 1 million hectares of federal forestland in the Pacific Northwest are rekindling a bit of the old-growth timber wars of the late 20th century. The changes announced by the Bureau of Land Management (BLM) on 5 August have environmentalists charging that it rolls back important habitat protections contained in the 1994 Northwest Forest Plan. That plan severely curtailed logging on 10 million hectares of federal lands in the name of protecting forests and species, including the northern spotted owl. Meanwhile, Oregon counties that get timber revenue from BLM land charge that the agency is still restricting logging too much. Some scientists are siding with the environmental groups, whereas others say the new approach is an advance that rests on science that has emerged over the last 2 decades. The outcome of this debate could set the stage for changes by the U.S. Forest Service, which controls most of the land covered by the 1994 plan. Author: Warren Cornwall

    Description: Degenerated retinas, globs of liver fat, wildly fluctuating blood sugar and insulin levels—all can spell trouble for people. But they are a way of life for Astyanax mexicanus, better known as the blind cave fish or Mexican tetra. For decades, biologists have studied these pale 6-centimeter-long fish to understand the ecological and evolutionary effects of subterranean life. Now, some researchers argue that the fishes' adaptations can shed light on human diseases including retinal degeneration and diabetes. And results presented last week at the 2016 International Conference on Subterranean Biology back up that view. The U.S. National Institutes of Health sees promise in cave fish as well, having agreed to fund the work of several cave fish biologists. Author: Elizabeth Pennisi

    Description: Concerns over deforestation have led to attempts to identify suitable areas for reforestation around the world (1). The most ambitious effort to date is the World Resources Institute (WRI) Atlas of Forest and Landscape Restoration Opportunities (1). This map is linked to a global plan to reforest degraded lands to offset anthropogenic CO2 emissions. The immediate target is the reforestation of 1.5 million km2 by 2020 (2, 3). Vast areas of open grassy vegetation have been identified as suitable for reforestation. But are all these grasslands secondary products of deforestations? Recent research shows that grasslands are often ancient and highly biodiverse, but it remains difficult to distinguish between primary and secondary grasslands on a large scale. Reforestation efforts thus risk converting ancient tropical grasslands to plantations. Author: William J. Bond

    Description: Soil microorganisms are central to the provision of food, feed, fiber, and medicine. Engineering of soil microbiomes may promote plant growth and plant health, thus contributing to food security and agricultural sustainability (1, 2). However, little is known about most soil microorganisms and their impact on plant health. Disease-suppressive soils offer microbiome-mediated protection of crop plants against infections by soil-borne pathogens. Understanding of the microbial consortia and mechanisms involved in disease suppression may help to better manage plants while reducing fertilizer and pesticide inputs. Authors: Jos M. Raaijmakers, Mark Mazzola

    Description: History tells us that the motivation for new environmental policy is much stronger when there is demonstrated ecological impact. Multinational agreements to stop the use of DDT followed the precipitous decline of predatory bird populations. Similarly, decisions to regulate emissions to prevent acid rain followed widespread degradation of aquatic habitats. Ideally, environmental policy should be catalyzed by scientific evidence rather than environmental catastrophe. As scientists, we can do our part by providing evidence that is relevant to the natural environment. On page 1213 of this issue, Lönnstedt and Eklöv (1) take an important step forward in this regard by reporting ecologically relevant evidence on a growing environmental issue: microplastic pollution.

    Description: Ecologists have shown through hundreds of experiments that ecological communities with more species produce higher levels of essential ecosystem functions such as biomass production, nutrient cycling, and pollination, but whether this finding holds in nature (that is, in large-scale and unmanipulated systems) is controversial. This knowledge gap is troubling because ecosystem services have been widely adopted as a justification for global biodiversity conservation. Here we show that, to provide crop pollination in natural systems, the number of bee species must increase by at least one order of magnitude compared with that in field experiments. This increase is driven by species turnover and its interaction with functional dominance, mechanisms that emerge only at large scales. Our results show that maintaining ecosystem services in nature requires many species, including relatively rare ones.

    Description: Billions of animals cross the globe each year during seasonal migrations, but efforts to monitor them are hampered by the unpredictability of their movements. We developed a bird migration forecast system at a continental scale by leveraging 23 years of spring observations to identify associations between atmospheric conditions and bird migration intensity. Our models explained up to 81% of variation in migration intensity across the United States at altitudes of 0 to 3000 meters, and performance remained high in forecasting events 1 to 7 days in advance (62 to 76% of variation was explained). Avian migratory movements across the United States likely exceed 500 million individuals per night during peak passage. Bird migration forecasts will reduce collisions with buildings, airplanes, and wind turbines; inform a variety of monitoring efforts; and engage the public.

    Description: Nie and colleagues suggest a key role for interannual climate variation as an explanation for the temporal dynamics of an unexpected 20-year reversal of biomass responses of C 3 -C 4 grasses to elevated CO 2 . However, we had already identified some climate-dependent differences in C 3 and C 4 responses to eCO 2 and shown that these could not fully explain the temporal dynamics we observed.

    Description: Biodiversity experiments have shown that species loss reduces ecosystem functioning in grassland. To test whether this result can be extrapolated to forests, the main contributors to terrestrial primary productivity, requires large-scale experiments. We manipulated tree species richness by planting more than 150,000 trees in plots with 1 to 16 species. Simulating multiple extinction scenarios, we found that richness strongly increased stand-level productivity. After 8 years, 16-species mixtures had accumulated over twice the amount of carbon found in average monocultures and similar amounts as those of two commercial monocultures. Species richness effects were strongly associated with functional and phylogenetic diversity. A shrub addition treatment reduced tree productivity, but this reduction was smaller at high shrub species richness. Our results encourage multispecies afforestation strategies to restore biodiversity and mitigate climate change.

    Description: Imagine a chain of uninterrupted wild landscapes spanning the savannas and forests of southern and central Africa, the woodlands of Poland and Belarus, and the tropical forests of Central and South America. By committing half of the planet's terrestrial and marine surface to nature, Edward O. Wilson believes that we can save millions of species, as well as humanity. This is Wilson's audacious proposal to stave off the coming biological apocalypse, the sixth mass extinction event, which he outlines in Half-Earth: Our Planet's Fight for Life. Author: Christine J.

    Description: Humans have long used animals as sentinels for threats to their own well-being. Canaries in coal mines are a classic example. On a global scale, studies of birds were key to detecting environmental problems caused by the excessive use of pesticides (1, 2). The recent loss of up to 98% of some vulture populations highlights the widespread dangerous effects of diclofenac use in cattle (3). Bee populations, sentinels for global insect losses, are also declining owing to the combined stress from pesticides and other environmental changes caused by humans, resulting in a widespread loss of pollination services (4). On page 819 of this issue, van Gils et al. (5) highlight another global ecological warning sign, this time linked to Arctic warming. They show that long-term changes in the body architecture of Arctic wading birds can affect their survival in their tropical wintering range. Authors: Martin Wikelski, Grigori Tertitski

    Description: Even as recently as early March, Australian coral reef scientists still hoped that the legendary Great Barrier Reef (GBR) would get off lightly in the current El Niño, the climate phenomenon that brings unusually warm water to the equatorial Pacific, stressing and often killing corals. No such luck. On 20 March, the GBR Marine Park Authority in Townsville, Australia, reported that divers were finding extensive coral bleaching—the loss of symbiotic algae—in remote northern areas of the reef. Many sections were already dead. Subsequent flyover surveys have confirmed an unfolding disaster, with only four of 520 reefs appearing unscathed. The GBR joins a lengthening list of reefs bleached because of the El Niño that started in late 2014. It is now the longest bleaching event ever, and many more corals worldwide will likely die.

    Description: Almost all land plants, including most trees, shrubs, and herbs, form symbiotic associations with mycorrhizal fungi (1). These soil fungi acquire nutrients that they transfer to their plant hosts in exchange for carbon (see the photo). Plants in natural vegetation can acquire up to 80% of nitrogen and phosphorus from their mycorrhizal associates (2). Individual mycorrhizal fungi can simultaneously colonize many plant hosts of the same species or different species. As a result, plants in natural communities are interconnected by mycorrhizal networks. Earlier studies with small tree seedlings revealed that carbon is transferred from one plant to another through these underground mycorrhizal pipelines (3). On page 342 of this issue, Klein et al. (4) show that interplant carbon transfer is not confined to tree seedlings. Author: Marcel G. A. van der Heijden

    Description: In an era of massive biodiversity loss, the greatest conservation success story has been the growth of protected land globally. Protected areas are the primary defense against biodiversity loss, but extensive human activity within their boundaries can undermine this. Using the most comprehensive global map of human pressure, we show that 6 million square kilometers (32.8%) of protected land is under intense human pressure. For protected areas designated before the Convention on Biological Diversity was ratified in 1992, 55% have since experienced human pressure increases. These increases were lowest in large, strict protected areas, showing that they are potentially effective, at least in some nations. Transparent reporting on human pressure within protected areas is now critical, as are global targets aimed at efforts required to halt biodiversity loss.

    Description: LaManna et al . (Reports, 30 June 2017, p. 1389) found higher conspecific negative density dependence in tree communities at lower latitudes, yielding a possible mechanistic explanation for the latitudinal diversity gradient. We show that their results are artifacts of a selective data transformation and a forced zero intercept in their fitted model. A corrected analysis shows no latitudinal trend.

    Description: Chisholm and Fung claim that our method of estimating conspecific negative density dependence (CNDD) in recruitment is systematically biased, and present an alternative method that shows no latitudinal pattern in CNDD. We demonstrate that their approach produces strongly biased estimates of CNDD, explaining why they do not detect a latitudinal pattern. We also address their methodological concerns using an alternative distance-weighted approach, which supports our original findings of a latitudinal gradient in CNDD and a latitudinal shift in the relationship between CNDD and species abundance.

    Description: Sabo et al . (Research Articles, 8 December 2017, p. 1270) use sophisticated analyses of flow and fishery data from the Lower Mekong Basin to design a "good" hydrograph that, if implemented by planned hydropower dams, would increase the catch by a factor of 3.7. However, the hydrograph is not implementable, and, if it were, it would devastate the fishery. Further, the analyses are questionable.

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

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

    Description: 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: It is unknown whether the human immune system frequently mounts a T cell response against mutations expressed by common epithelial cancers. Using a next-generation sequencing approach combined with high-throughput immunologic screening, we demonstrated that tumor-infiltrating lymphocytes (TILs) from 9 out of 10 patients with metastatic gastrointestinal cancers contained CD4(+) and/or CD8(+) T cells that recognized one to three neo-epitopes derived from somatic mutations expressed by the patient's own tumor. There were no immunogenic epitopes shared between these patients. However, we identified in one patient a human leukocyte antigen-C*08:02-restricted T cell receptor from CD8(+) TILs that targeted the KRAS(G12D) hotspot driver mutation found in many human cancers. Thus, a high frequency of patients with common gastrointestinal cancers harbor immunogenic mutations that can potentially be exploited for the development of highly personalized immunotherapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Eric -- Ahmadzadeh, Mojgan -- Lu, Yong-Chen -- Gros, Alena -- Turcotte, Simon -- Robbins, Paul F -- Gartner, Jared J -- Zheng, Zhili -- Li, Yong F -- Ray, Satyajit -- Wunderlich, John R -- Somerville, Robert P -- Rosenberg, Steven A -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 11;350(6266):1387-90. doi: 10.1126/science.aad1253.

    Description: Monoclonal antibodies directed against cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), such as ipilimumab, yield considerable clinical benefit for patients with metastatic melanoma by inhibiting immune checkpoint activity, but clinical predictors of response to these therapies remain incompletely characterized. To investigate the roles of tumor-specific neoantigens and alterations in the tumor microenvironment in the response to ipilimumab, we analyzed whole exomes from pretreatment melanoma tumor biopsies and matching germline tissue samples from 110 patients. For 40 of these patients, we also obtained and analyzed transcriptome data from the pretreatment tumor samples. Overall mutational load, neoantigen load, and expression of cytolytic markers in the immune microenvironment were significantly associated with clinical benefit. However, no recurrent neoantigen peptide sequences predicted responder patient populations. Thus, detailed integrated molecular characterization of large patient cohorts may be needed to identify robust determinants of response and resistance to immune checkpoint inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Shukla, Sachet A -- Blank, Christian -- Zimmer, Lisa -- Sucker, Antje -- Hillen, Uwe -- Foppen, Marnix H Geukes -- Goldinger, Simone M -- Utikal, Jochen -- Hassel, Jessica C -- Weide, Benjamin -- Kaehler, Katharina C -- Loquai, Carmen -- Mohr, Peter -- Gutzmer, Ralf -- Dummer, Reinhard -- Gabriel, Stacey -- Wu, Catherine J -- Schadendorf, Dirk -- Garraway, Levi A -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):207-11. doi: 10.1126/science.aad0095.

    Description: Antibodies targeting CTLA-4 have been successfully used as cancer immunotherapy. We find that the antitumor effects of CTLA-4 blockade depend on distinct Bacteroides species. In mice and patients, T cell responses specific for B. thetaiotaomicron or B. fragilis were associated with the efficacy of CTLA-4 blockade. Tumors in antibiotic-treated or germ-free mice did not respond to CTLA blockade. This defect was overcome by gavage with B. fragilis, by immunization with B. fragilis polysaccharides, or by adoptive transfer of B. fragilis-specific T cells. Fecal microbial transplantation from humans to mice confirmed that treatment of melanoma patients with antibodies against CTLA-4 favored the outgrowth of B. fragilis with anticancer properties. This study reveals a key role for Bacteroidales in the immunostimulatory effects of CTLA-4 blockade.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721659/" 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/PMC4721659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vetizou, Marie -- Pitt, Jonathan M -- Daillere, Romain -- Lepage, Patricia -- Waldschmitt, Nadine -- Flament, Caroline -- Rusakiewicz, Sylvie -- Routy, Bertrand -- Roberti, Maria P -- Duong, Connie P M -- Poirier-Colame, Vichnou -- Roux, Antoine -- Becharef, Sonia -- Formenti, Silvia -- Golden, Encouse -- Cording, Sascha -- Eberl, Gerard -- Schlitzer, Andreas -- Ginhoux, Florent -- Mani, Sridhar -- Yamazaki, Takahiro -- Jacquelot, Nicolas -- Enot, David P -- Berard, Marion -- Nigou, Jerome -- Opolon, Paule -- Eggermont, Alexander -- Woerther, Paul-Louis -- Chachaty, Elisabeth -- Chaput, Nathalie -- Robert, Caroline -- Mateus, Christina -- Kroemer, Guido -- Raoult, Didier -- Boneca, Ivo Gomperts -- Carbonnel, Franck -- Chamaillard, Mathias -- Zitvogel, Laurence -- R01 CA161879/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1079-84. doi: 10.1126/science.aad1329.

    Description: Although people may endorse egalitarianism and tolerance, social biases can remain operative and drive harmful actions in an unconscious manner. Here, we investigated training to reduce implicit racial and gender bias. Forty participants processed counterstereotype information paired with one sound for each type of bias. Biases were reduced immediately after training. During subsequent slow-wave sleep, one sound was unobtrusively presented to each participant, repeatedly, to reactivate one type of training. Corresponding bias reductions were fortified in comparison with the social bias not externally reactivated during sleep. This advantage remained 1 week later, the magnitude of which was associated with time in slow-wave and rapid-eye-movement sleep after training. We conclude that memory reactivation during sleep enhances counterstereotype training and that maintaining a bias reduction is sleep-dependent.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4467959/" 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/PMC4467959/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Xiaoqing -- Antony, James W -- Creery, Jessica D -- Vargas, Iliana M -- Bodenhausen, Galen V -- Paller, Ken A -- F31 MH100958/MH/NIMH NIH HHS/ -- F31-MH100958/MH/NIMH NIH HHS/ -- T32 AG020506/AG/NIA NIH HHS/ -- T32-AG020418/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 May 29;348(6238):1013-5. doi: 10.1126/science.aaa3841.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Northwestern University, Evanston, IL 60208, USA.

    Description: We studied the distributional preferences of an elite cadre of Yale Law School students, a group that will assume positions of power in U.S. society. Our experimental design allows us to test whether redistributive decisions are consistent with utility maximization and to decompose underlying preferences into two qualitatively different tradeoffs: fair-mindedness versus self-interest, and equality versus efficiency. Yale Law School subjects are more consistent than subjects drawn from the American Life Panel, a diverse sample of Americans. Relative to the American Life Panel, Yale Law School subjects are also less fair-minded and substantially more efficiency-focused. We further show that our measure of equality-efficiency tradeoffs predicts Yale Law School students' career choices: Equality-minded subjects are more likely to be employed at nonprofit organizations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fisman, Raymond -- Jakiela, Pamela -- Kariv, Shachar -- Markovits, Daniel -- New York, N.Y. -- Science. 2015 Sep 18;349(6254):aab0096. doi: 10.1126/science.aab0096.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, Boston University, Boston, MA, USA. rfisman@bu.edu. ; Department of Agricultural and Resource Economics, University of Maryland, College Park, MD, USA. ; Department of Economics, University of California, Berkeley, Berkely, CA, USA. ; Yale Law School, Yale University, New Haven, CT, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26383958" target="_blank"〉PubMed〈/a〉

    Description: Democracies depend on the support of the general population, but little is known about the determinants of this support. We investigated whether support for democracy increases with the length of time spent under the system and whether preferences are thus affected by the political system. Relying on 380,000 individual-level observations from 104 countries over the years 1994 to 2013, and exploiting individual-level variation within a country and a given year in the length of time spent under democracy, we find evidence that political preferences are endogenous. For new democracies, our findings imply that popular support needs time to develop. For example, the effect of around 8.5 more years of democratic experience corresponds to the difference in support for democracy between primary and secondary education.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fuchs-Schundeln, Nicola -- Schundeln, Matthias -- New York, N.Y. -- Science. 2015 Mar 6;347(6226):1145-8. doi: 10.1126/science.aaa0880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Goethe University Frankfurt, 60320 Frankfurt, Germany. fuchs@wiwi.uni-frankfurt.de schuendeln@wiwi.uni-frankfurt.de.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25745172" target="_blank"〉PubMed〈/a〉

    Description: Amyotrophic lateral sclerosis (ALS) is a devastating neurological disease with no effective treatment. We report the results of a moderate-scale sequencing study aimed at increasing the number of genes known to contribute to predisposition for ALS. We performed whole-exome sequencing of 2869 ALS patients and 6405 controls. Several known ALS genes were found to be associated, and TBK1 (the gene encoding TANK-binding kinase 1) was identified as an ALS gene. TBK1 is known to bind to and phosphorylate a number of proteins involved in innate immunity and autophagy, including optineurin (OPTN) and p62 (SQSTM1/sequestosome), both of which have also been implicated in ALS. These observations reveal a key role of the autophagic pathway in ALS and suggest specific targets for therapeutic intervention.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4437632/" 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/PMC4437632/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cirulli, Elizabeth T -- Lasseigne, Brittany N -- Petrovski, Slave -- Sapp, Peter C -- Dion, Patrick A -- Leblond, Claire S -- Couthouis, Julien -- Lu, Yi-Fan -- Wang, Quanli -- Krueger, Brian J -- Ren, Zhong -- Keebler, Jonathan -- Han, Yujun -- Levy, Shawn E -- Boone, Braden E -- Wimbish, Jack R -- Waite, Lindsay L -- Jones, Angela L -- Carulli, John P -- Day-Williams, Aaron G -- Staropoli, John F -- Xin, Winnie W -- Chesi, Alessandra -- Raphael, Alya R -- McKenna-Yasek, Diane -- Cady, Janet -- Vianney de Jong, J M B -- Kenna, Kevin P -- Smith, Bradley N -- Topp, Simon -- Miller, Jack -- Gkazi, Athina -- FALS Sequencing Consortium -- Al-Chalabi, Ammar -- van den Berg, Leonard H -- Veldink, Jan -- Silani, Vincenzo -- Ticozzi, Nicola -- Shaw, Christopher E -- Baloh, Robert H -- Appel, Stanley -- Simpson, Ericka -- Lagier-Tourenne, Clotilde -- Pulst, Stefan M -- Gibson, Summer -- Trojanowski, John Q -- Elman, Lauren -- McCluskey, Leo -- Grossman, Murray -- Shneider, Neil A -- Chung, Wendy K -- Ravits, John M -- Glass, Jonathan D -- Sims, Katherine B -- Van Deerlin, Vivianna M -- Maniatis, Tom -- Hayes, Sebastian D -- Ordureau, Alban -- Swarup, Sharan -- Landers, John -- Baas, Frank -- Allen, Andrew S -- Bedlack, Richard S -- Harper, J Wade -- Gitler, Aaron D -- Rouleau, Guy A -- Brown, Robert -- Harms, Matthew B -- Cooper, Gregory M -- Harris, Tim -- Myers, Richard M -- Goldstein, David B -- 089701/Wellcome Trust/United Kingdom -- K08 NS075094/NS/NINDS NIH HHS/ -- P01 AG017586/AG/NIA NIH HHS/ -- P01 AG032953/AG/NIA NIH HHS/ -- P50 AG025688/AG/NIA NIH HHS/ -- R37 NS033123/NS/NINDS NIH HHS/ -- R37 NS083524/NS/NINDS NIH HHS/ -- T32 GM007754/GM/NIGMS NIH HHS/ -- TL1 TR001066/TR/NCATS NIH HHS/ -- UL1 TR001067/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2015 Mar 27;347(6229):1436-41. doi: 10.1126/science.aaa3650.

    Description: Research suggesting that political conservatives are happier than political liberals has relied exclusively on self-report measures of subjective well-being. We show that this finding is fully mediated by conservatives' self-enhancing style of self-report (study 1; N = 1433) and then describe three studies drawing from "big data" sources to assess liberal-conservative differences in happiness-related behavior (studies 2 to 4; N = 4936). Relative to conservatives, liberals more frequently used positive emotional language in their speech and smiled more intensely and genuinely in photographs. Our results were consistent across large samples of online survey takers, U.S. politicians, Twitter users, and LinkedIn users. Our findings illustrate the nuanced relationship between political ideology, self-enhancement, and happiness and illuminate the contradictory ways that happiness differences can manifest across behavior and self-reports.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wojcik, Sean P -- Hovasapian, Arpine -- Graham, Jesse -- Motyl, Matt -- Ditto, Peter H -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1243-6. doi: 10.1126/science.1260817.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Social Behavior, University of California, Irvine, CA 92697, USA. swojcik@uci.edu phditto@uci.edu. ; Department of Psychology and Social Behavior, University of California, Irvine, CA 92697, USA. ; Department of Psychology, University of Southern California, CA 90089, USA. ; University of Illinois, Chicago, IL 60607, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25766233" target="_blank"〉PubMed〈/a〉

    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: Steroids regulate cell proliferation, tissue development, and cell signaling via two pathways: a nuclear receptor mechanism and genome-independent signaling. Sperm activation, egg maturation, and steroid-induced anesthesia are executed via the latter pathway, the key components of which remain unknown. Here, we present characterization of the human sperm progesterone receptor that is conveyed by the orphan enzyme alpha/beta hydrolase domain-containing protein 2 (ABHD2). We show that ABHD2 is highly expressed in spermatozoa, binds progesterone, and acts as a progesterone-dependent lipid hydrolase by depleting the endocannabinoid 2-arachidonoylglycerol (2AG) from plasma membrane. The 2AG inhibits the sperm calcium channel (CatSper), and its removal leads to calcium influx via CatSper and ensures sperm activation. This study reveals that progesterone-activated endocannabinoid depletion by ABHD2 is a general mechanism by which progesterone exerts its genome-independent action and primes sperm for fertilization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Melissa R -- Mannowetz, Nadja -- Iavarone, Anthony T -- Safavi, Rojin -- Gracheva, Elena O -- Smith, James F -- Hill, Rose Z -- Bautista, Diana M -- Kirichok, Yuriy -- Lishko, Polina V -- 1S10OD020062-01/OD/NIH HHS/ -- R01 AR059385/AR/NIAMS NIH HHS/ -- R01AR059385/AR/NIAMS NIH HHS/ -- R01GM111802/GM/NIGMS NIH HHS/ -- R01HD068914/HD/NICHD NIH HHS/ -- R21HD081403/HD/NICHD NIH HHS/ -- S10RR025622/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):555-9. doi: 10.1126/science.aad6887.

    Description: Examining complete gene knockouts within a viable organism can inform on gene function. We sequenced the exomes of 3222 British adults of Pakistani heritage with high parental relatedness, discovering 1111 rare-variant homozygous genotypes with predicted loss of function (knockouts) in 781 genes. We observed 13.7% fewer homozygous knockout genotypes than we expected, implying an average load of 1.6 recessive-lethal-equivalent loss-of-function (LOF) variants per adult. When genetic data were linked to the individuals' lifelong health records, we observed no significant relationship between gene knockouts and clinical consultation or prescription rate. In this data set, we identified a healthy PRDM9-knockout mother and performed phased genome sequencing on her, her child, and control individuals. Our results show that meiotic recombination sites are localized away from PRDM9-dependent hotspots. Thus, natural LOF variants inform on essential genetic loci and demonstrate PRDM9 redundancy in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Narasimhan, Vagheesh M -- Hunt, Karen A -- Mason, Dan -- Baker, Christopher L -- Karczewski, Konrad J -- Barnes, Michael R -- Barnett, Anthony H -- Bates, Chris -- Bellary, Srikanth -- Bockett, Nicholas A -- Giorda, Kristina -- Griffiths, Christopher J -- Hemingway, Harry -- Jia, Zhilong -- Kelly, M Ann -- Khawaja, Hajrah A -- Lek, Monkol -- McCarthy, Shane -- McEachan, Rosie -- O'Donnell-Luria, Anne -- Paigen, Kenneth -- Parisinos, Constantinos A -- Sheridan, Eamonn -- Southgate, Laura -- Tee, Louise -- Thomas, Mark -- Xue, Yali -- Schnall-Levin, Michael -- Petkov, Petko M -- Tyler-Smith, Chris -- Maher, Eamonn R -- Trembath, Richard C -- MacArthur, Daniel G -- Wright, John -- Durbin, Richard -- van Heel, David A -- GM 099640/GM/NIGMS NIH HHS/ -- MR/M009017/1/Medical Research Council/United Kingdom -- R01 GM104371/GM/NIGMS NIH HHS/ -- R01GM104371/GM/NIGMS NIH HHS/ -- WT098051/Wellcome Trust/United Kingdom -- WT099769/Wellcome Trust/United Kingdom -- WT101597/Wellcome Trust/United Kingdom -- WT102627/Wellcome Trust/United Kingdom -- British Heart Foundation/United Kingdom -- Arthritis Research UK/United Kingdom -- Cancer Research UK/United Kingdom -- Department of Health/United Kingdom -- Chief Scientist Office/United Kingdom -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):474-7. doi: 10.1126/science.aac8624.

    Description: In a classical view of hematopoiesis, the various blood cell lineages arise via a hierarchical scheme starting with multipotent stem cells that become increasingly restricted in their differentiation potential through oligopotent and then unipotent progenitors. We developed a cell-sorting scheme to resolve myeloid (My), erythroid (Er), and megakaryocytic (Mk) fates from single CD34(+) cells and then mapped the progenitor hierarchy across human development. Fetal liver contained large numbers of distinct oligopotent progenitors with intermingled My, Er, and Mk fates. However, few oligopotent progenitor intermediates were present in the adult bone marrow. Instead, only two progenitor classes predominate, multipotent and unipotent, with Er-Mk lineages emerging from multipotent cells. The developmental shift to an adult "two-tier" hierarchy challenges current dogma and provides a revised framework to understand normal and disease states of human hematopoiesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Notta, Faiyaz -- Zandi, Sasan -- Takayama, Naoya -- Dobson, Stephanie -- Gan, Olga I -- Wilson, Gavin -- Kaufmann, Kerstin B -- McLeod, Jessica -- Laurenti, Elisa -- Dunant, Cyrille F -- McPherson, John D -- Stein, Lincoln D -- Dror, Yigal -- Dick, John E -- Canadian Institutes of Health Research/Canada -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2016 Jan 8;351(6269):aab2116. doi: 10.1126/science.aab2116.

    Description: Influenza A virus (IAV) causes up to half a million deaths worldwide annually, 90% of which occur in older adults. We show that IAV-infected monocytes from older humans have impaired antiviral interferon production but retain intact inflammasome responses. To understand the in vivo consequence, we used mice expressing a functional Mx gene encoding a major interferon-induced effector against IAV in humans. In Mx1-intact mice with weakened resistance due to deficiencies in Mavs and Tlr7, we found an elevated respiratory bacterial burden. Notably, mortality in the absence of Mavs and Tlr7 was independent of viral load or MyD88-dependent signaling but dependent on bacterial burden, caspase-1/11, and neutrophil-dependent tissue damage. Therefore, in the context of weakened antiviral resistance, vulnerability to IAV disease is a function of caspase-dependent pathology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pillai, Padmini S -- Molony, Ryan D -- Martinod, Kimberly -- Dong, Huiping -- Pang, Iris K -- Tal, Michal C -- Solis, Angel G -- Bielecki, Piotr -- Mohanty, Subhasis -- Trentalange, Mark -- Homer, Robert J -- Flavell, Richard A -- Wagner, Denisa D -- Montgomery, Ruth R -- Shaw, Albert C -- Staeheli, Peter -- Iwasaki, Akiko -- 5T32HL066987-13/HL/NHLBI NIH HHS/ -- AI062428/AI/NIAID NIH HHS/ -- AI064705/AI/NIAID NIH HHS/ -- AI081884/AI/NIAID NIH HHS/ -- F31 AG039163/AG/NIA NIH HHS/ -- HHSN272201100019C/PHS HHS/ -- K24 AG02489/AG/NIA NIH HHS/ -- K24 AG042489/AG/NIA NIH HHS/ -- N01 AI500031/AI/NIAID NIH HHS/ -- P30 AG21342/AG/NIA NIH HHS/ -- R01HL102101/HL/NHLBI NIH HHS/ -- R01HL125501/HL/NHLBI NIH HHS/ -- T32 AI007019-36/AI/NIAID NIH HHS/ -- T32 AI007019-38/AI/NIAID NIH HHS/ -- T32 AI055403/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):463-6. doi: 10.1126/science.aaf3926.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunobiology, Yale School of Medicine, New Haven, CT 06520, USA. ; Program in Cellular and Molecular Medicine, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA. ; Section of Infectious Diseases, Department of Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA. ; Department of Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA. ; Department of Pathology, Yale School of Medicine, New Haven, CT 06520, USA. ; Department of Immunobiology, Yale School of Medicine, New Haven, CT 06520, USA.

    Description: Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves, the latitudinal gradient of leaf size has not been well quantified nor the key climatic drivers convincingly identified. Here, we characterize worldwide patterns in leaf size. Large-leaved species predominate in wet, hot, sunny environments; small-leaved species typify hot, sunny environments only in arid conditions; small leaves are also found in high latitudes and elevations. By modeling the balance of leaf energy inputs and outputs, we show that daytime and nighttime leaf-to-air temperature differences are key to geographic gradients in leaf size. This knowledge can enrich "next-generation" vegetation models in which leaf temperature and water use during photosynthesis play key roles.

    Description: The tropics have by far the highest species diversity on Earth. Over two-thirds of terrestrial vertebrates occur in tropical moist forests (1). The species diversity is also highest in the tropics for several other taxa, such as vascular plants and arthropods, and in other realms, including freshwater and marine ecosystems. These latitudinal gradients were described decades ago (2), but recent work has yielded detailed knowledge of species-richness patterns. For example, Hurlbert and Jetz suggest that global maps of terrestrial vertebrate species richness are now accurate at resolutions of 100 to 200 km (3). Yet, little is known about the global patterns of genetic diversity. On page 1532 of this issue, Miraldo et al. help to fill this gap by presenting a global map of intraspecific (within-species) genetic diversity of amphibians and terrestrial mammals (4).

    Description: Theory predicts that higher biodiversity in the tropics is maintained by specialized interactions among plants and their natural enemies that result in conspecific negative density dependence (CNDD). By using more than 3000 species and nearly 2.4 million trees across 24 forest plots worldwide, we show that global patterns in tree species diversity reflect not only stronger CNDD at tropical versus temperate latitudes but also a latitudinal shift in the relationship between CNDD and species abundance. CNDD was stronger for rare species at tropical versus temperate latitudes, potentially causing the persistence of greater numbers of rare species in the tropics. Our study reveals fundamental differences in the nature of local-scale biotic interactions that contribute to the maintenance of species diversity across temperate and tropical communities.

    Description: Neonicotinoid seed dressings have caused concern world-wide. We use large field experiments to assess the effects of neonicotinoid-treated crops on three bee species across three countries (Hungary, Germany, and the United Kingdom). Winter-sown oilseed rape was grown commercially with either seed coatings containing neonicotinoids (clothianidin or thiamethoxam) or no seed treatment (control). For honey bees, we found both negative (Hungary and United Kingdom) and positive (Germany) effects during crop flowering. In Hungary, negative effects on honey bees (associated with clothianidin) persisted over winter and resulted in smaller colonies in the following spring (24% declines). In wild bees ( Bombus terrestris and Osmia bicornis ), reproduction was negatively correlated with neonicotinoid residues. These findings point to neonicotinoids causing a reduced capacity of bee species to establish new populations in the year following exposure.

    Description: Networks with a modular structure are expected to have a lower risk of global failure. However, this theoretical result has remained untested until now. We used an experimental microarthropod metapopulation to test the effect of modularity on the response to perturbation. We perturbed one local population and measured the spread of the impact of this perturbation, both within and between modules. Our results show the buffering capacity of modular networks. To assess the generality of our findings, we then analyzed a dynamical model of our system. We show that in the absence of perturbations, modularity is negatively correlated with metapopulation size. However, even when a small local perturbation occurs, this negative effect is offset by a buffering effect that protects the majority of the nodes from the perturbation.

    Description: Eutrophication, or excessive nutrient enrichment, threatens water resources across the globe. We show that climate change–induced precipitation changes alone will substantially increase (19 ± 14%) riverine total nitrogen loading within the continental United States by the end of the century for the "business-as-usual" scenario. The impacts, driven by projected increases in both total and extreme precipitation, will be especially strong for the Northeast and the corn belt of the United States. Offsetting this increase would require a 33 ± 24% reduction in nitrogen inputs, representing a massive management challenge. Globally, changes in precipitation are especially likely to also exacerbate eutrophication in India, China, and Southeast Asia. It is therefore imperative that water quality management strategies account for the impact of projected future changes in precipitation on nitrogen loading.

    Description: The mosquito’s innate immune system controls both Plasmodium and bacterial infections. We investigated the competitiveness of mosquitoes genetically modified to alter expression of their own anti- Plasmodium immune genes in a mixed-cage population with wild-type mosquitoes. We observed that genetically modified mosquitoes with increased immune activity in the midgut tissue did not have an observed fitness disadvantage and showed reduced microbial loads in both the midgut and reproductive organs. These changes result in a mating preference of genetically modified males for wild-type females, whereas wild-type males prefer genetically modified females. These changes foster the spread of the genetic modification in a mosquito cage population.

    Description: The 2011 East Japan earthquake generated a massive tsunami that launched an extraordinary transoceanic biological rafting event with no known historical precedent. We document 289 living Japanese coastal marine species from 16 phyla transported over 6 years on objects that traveled thousands of kilometers across the Pacific Ocean to the shores of North America and Hawai‘i. Most of this dispersal occurred on nonbiodegradable objects, resulting in the longest documented transoceanic survival and dispersal of coastal species by rafting. Expanding shoreline infrastructure has increased global sources of plastic materials available for biotic colonization and also interacts with climate change–induced storms of increasing severity to eject debris into the oceans. In turn, increased ocean rafting may intensify species invasions.

    Description: Two- to threefold variations in sleep length were observed in 12 subjects living on self-selected schedules in an environment free of time cues. The duration of polygraphically recorded sleep episodes was highly correlated with the circadian phase of the body temperature rhythm at bedtime and not with the length of prior wakefulness. Furthermore, the rate of REM (rapid eye movement) sleep accumulation , REM latency, bedtime selection, and self-rated alertness assessments were also correlated with the body temperature rhythm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Czeisler, C A -- Weitzman, E d -- Moore-Ede, M C -- Zimmerman, J C -- Knauer, R S -- AG-00792/AG/NIA NIH HHS/ -- GM-07365/GM/NIGMS NIH HHS/ -- MH-28460/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 12;210(4475):1264-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434029" target="_blank"〉PubMed〈/a〉

    Description: Heroin-dependent men were given buprenorphine (a partial opiate agonist-antagonist) or a placebo under duoble-blind conditions on a clinical research ward where they could acquire heroin (21 to 40.5 milligrams per day, intravenously). Buprenorphine significantly (P less than .001) suppressed the self-administration of heroin over 10 days. Control subjects took between 93 and 100 percent of the available heroin. The effects of buprenorphine were dose-dependent; a dose of 8 milligrams per day reduced heroin use by 69 to 98 percent; a dose of 4 milligrams per day reduced heroin use by 45 percent. Termination of buprenorphie maintenance did not result in opiate withdrawal signs or symptoms. The subjects liked buprenorphine and indicated that it was preferable to methadone or naltrexone. Buprenorphine should be a safe and effective new pharmacotherapy for heroin dependence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mello, N K -- Mendelson, J H -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):657-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352279" target="_blank"〉PubMed〈/a〉

    Description: The ability to see spatial structures of a wide range of sizes was measured for two groups of observers (mean ages, 18 and 73 years). All observers had good visual acuity. Although older and younger observers did not differ in ability to see targets with fine structure (high spatial frequencies), older observers were only one-third as sensitive to targets with coarse structure (low spatial frequencies) as were younger observers or to changes in criterion. Older observers were also less able than younger observers to see moving targets. The reduced sensitivity of the older observers may adversely affect routine perceptual activities, such as face recognition and visually guided postural behavior, that depend upon low spatial frequencies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sekuler, R -- Hutman, L P -- Owsley, C J -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1255-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403884" target="_blank"〉PubMed〈/a〉

    Description: A new technique has been developed for identifying, in humans, dynamic spatiotemporal electrical patterns of the brain during purposive behaviors. In this method, single-trial time-series correlations between brain macropotentials recorded from different scalp sites are analyzed by distribution-independent mathematical pattern recognition. Dynamic patterns of correlation clearly distinguished two brief visuomotor tasks differing only in type of mental judgement required (spatial or numeric). These complex patterns shifted in the anterior-posterior and left-right axes between successive 175-millisecond intervals, indicating that many areas in both cerebral hemispheres were involved even in these simple judgements. These patterns were not obtainable by conventional analysis of averaged evoked potentials or by linear analysis of correlations, suggesting that the new technique will advance the study of human brain activity related to cognition and goal-directed behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Doyle, J C -- Cutillo, B A -- Schaffer, R E -- Tannehill, R S -- Ghannam, J H -- Gilcrease, V A -- Yeager, C L -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):918-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256287" target="_blank"〉PubMed〈/a〉
