    [Perspective] How much biodiversity loss is too much? (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science

    Beschreibung: 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

    Beschreibung: 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

    [Perspective] Can Apulia's olive trees be saved? (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-07-22
    Beschreibung: 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

    Beschreibung: 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

    [Perspective] Thermal trouble in the tropics (2016)

    In: Science
    Details
    Publikationsdatum: 2016-03-25
    Beschreibung: 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

    [Perspective] How frigate birds soar around the doldrums (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-07-01
    Beschreibung: 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

    [Perspective] How climate change affects plants' sex lives (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-07-01
    Beschreibung: 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

    [In Depth] Scientists split on Oregon old-growth forest plan (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-08-13
    Beschreibung: 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

    [In Depth] Blind cave fish may provide insights into human health (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-06-24
    Beschreibung: 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

    [Perspective] Ancient grasslands at risk (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-08-16
    Beschreibung: 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

    Beschreibung: 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

    [Perspective] Ecologically relevant data are policy-relevant data (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-06-03
    Beschreibung: 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.

    Species turnover promotes the importance of bee diversity for crop pollination at regional scales (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2018-02-16
    Beschreibung: 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.

    A continental system for forecasting bird migration (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2018-09-14
    Beschreibung: 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.

    Response to Comment on "Unexpected reversal of C3 versus C4 grass response to elevated CO2 during a 20-year field experiment" (2018)

    Publikationsdatum: 2018-09-14
    Beschreibung: 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.

    Impacts of species richness on productivity in a large-scale subtropical forest experiment (2018)

    Beschreibung: 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.

    Prediction of individual brain maturity using fMRI (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-09-11
    Beschreibung: Group functional connectivity magnetic resonance imaging (fcMRI) studies have documented reliable changes in human functional brain maturity over development. Here we show that support vector machine-based multivariate pattern analysis extracts sufficient information from fcMRI data to make accurate predictions about individuals' brain maturity across development. The use of only 5 minutes of resting-state fcMRI data from 238 scans of typically developing volunteers (ages 7 to 30 years) allowed prediction of individual brain maturity as a functional connectivity maturation index. The resultant functional maturation curve accounted for 55% of the sample variance and followed a nonlinear asymptotic growth curve shape. The greatest relative contribution to predicting individual brain maturity was made by the weakening of short-range functional connections between the adult brain's major functional networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3135376/" 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/PMC3135376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dosenbach, Nico U F -- Nardos, Binyam -- Cohen, Alexander L -- Fair, Damien A -- Power, Jonathan D -- Church, Jessica A -- Nelson, Steven M -- Wig, Gagan S -- Vogel, Alecia C -- Lessov-Schlaggar, Christina N -- Barnes, Kelly Anne -- Dubis, Joseph W -- Feczko, Eric -- Coalson, Rebecca S -- Pruett, John R Jr -- Barch, Deanna M -- Petersen, Steven E -- Schlaggar, Bradley L -- DA027046/DA/NIDA NIH HHS/ -- EY16336/EY/NEI NIH HHS/ -- HD057076/HD/NICHD NIH HHS/ -- MH62130/MH/NIMH NIH HHS/ -- NS00169011/NS/NINDS NIH HHS/ -- NS053425/NS/NINDS NIH HHS/ -- NS32979/NS/NINDS NIH HHS/ -- NS41255/NS/NINDS NIH HHS/ -- NS46424/NS/NINDS NIH HHS/ -- NS51281/NS/NINDS NIH HHS/ -- NS55582/NS/NINDS NIH HHS/ -- R01 HD057076/HD/NICHD NIH HHS/ -- R01 HD057076-04/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 10;329(5997):1358-61. doi: 10.1126/science.1194144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Washington University School of Medicine, St. Louis, MO 63110, USA. ndosenbach@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20829489" target="_blank"〉PubMed〈/a〉

    Effectiveness and safety of tenofovir gel, an antiretroviral microbicide, for the prevention of HIV infection in women (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-07-21
    Beschreibung: The Centre for the AIDS Program of Research in South Africa (CAPRISA) 004 trial assessed the effectiveness and safety of a 1% vaginal gel formulation of tenofovir, a nucleotide reverse transcriptase inhibitor, for the prevention of HIV acquisition in women. A double-blind, randomized controlled trial was conducted comparing tenofovir gel (n = 445 women) with placebo gel (n = 444 women) in sexually active, HIV-uninfected 18- to 40-year-old women in urban and rural KwaZulu-Natal, South Africa. HIV serostatus, safety, sexual behavior, and gel and condom use were assessed at monthly follow-up visits for 30 months. HIV incidence in the tenofovir gel arm was 5.6 per 100 women-years (person time of study observation) (38 out of 680.6 women-years) compared with 9.1 per 100 women-years (60 out of 660.7 women-years) in the placebo gel arm (incidence rate ratio = 0.61; P = 0.017). In high adherers (gel adherence 〉 80%), HIV incidence was 54% lower (P = 0.025) in the tenofovir gel arm. In intermediate adherers (gel adherence 50 to 80%) and low adherers (gel adherence 〈 50%), the HIV incidence reduction was 38 and 28%, respectively. Tenofovir gel reduced HIV acquisition by an estimated 39% overall, and by 54% in women with high gel adherence. No increase in the overall adverse event rates was observed. There were no changes in viral load and no tenofovir resistance in HIV seroconverters. Tenofovir gel could potentially fill an important HIV prevention gap, especially for women unable to successfully negotiate mutual monogamy or condom use.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3001187/" 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/PMC3001187/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdool Karim, Quarraisha -- Abdool Karim, Salim S -- Frohlich, Janet A -- Grobler, Anneke C -- Baxter, Cheryl -- Mansoor, Leila E -- Kharsany, Ayesha B M -- Sibeko, Sengeziwe -- Mlisana, Koleka P -- Omar, Zaheen -- Gengiah, Tanuja N -- Maarschalk, Silvia -- Arulappan, Natasha -- Mlotshwa, Mukelisiwe -- Morris, Lynn -- Taylor, Douglas -- CAPRISA 004 Trial Group -- AI51794/AI/NIAID NIH HHS/ -- D43 TW000231/TW/FIC NIH HHS/ -- D43 TW000231-17/TW/FIC NIH HHS/ -- D43TW00231/TW/FIC NIH HHS/ -- U01 AI068619/AI/NIAID NIH HHS/ -- U01AI068633/AI/NIAID NIH HHS/ -- U01AI46749/AI/NIAID NIH HHS/ -- U19 AI051794/AI/NIAID NIH HHS/ -- U19 AI051794-05/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 3;329(5996):1168-74. doi: 10.1126/science.1193748.

    Dopaminergic network differences in human impulsivity (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-07-31
    Beschreibung: Dopamine (DA) has long been implicated in impulsivity, but the precise mechanisms linking human variability in DA signaling to differences in impulsive traits remain largely unknown. By using a dual-scan positron emission tomography approach in healthy human volunteers with amphetamine and the D2/D3 ligand [18F]fallypride, we found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving. Path analysis confirmed that the impact of decreased midbrain D2/D3 autoreceptor availability on trait impulsivity is mediated in part through its effect on stimulated striatal DA release.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3161413/" 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/PMC3161413/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buckholtz, Joshua W -- Treadway, Michael T -- Cowan, Ronald L -- Woodward, Neil D -- Li, Rui -- Ansari, M Sib -- Baldwin, Ronald M -- Schwartzman, Ashley N -- Shelby, Evan S -- Smith, Clarence E -- Kessler, Robert M -- Zald, David H -- R01 DA019670/DA/NIDA NIH HHS/ -- R01 DA019670-04/DA/NIDA NIH HHS/ -- R01DA019670-04/DA/NIDA NIH HHS/ -- T32 MH018921/MH/NIMH NIH HHS/ -- T32 MH018921-22/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):532. doi: 10.1126/science.1185778.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Vanderbilt University, Nashville, TN 37240, USA. joshua.buckholtz@vanderbilt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671181" target="_blank"〉PubMed〈/a〉

    Divided representation of concurrent goals in the human frontal lobes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-04-17
    Beschreibung: The anterior prefrontal cortex (APC) confers on humans the ability to simultaneously pursue several goals. How does the brain's motivational system, including the medial frontal cortex (MFC), drive the pursuit of concurrent goals? Using brain imaging, we observed that the left and right MFC, which jointly drive single-task performance according to expected rewards, divide under dual-task conditions: While the left MFC encodes the rewards driving one task, the right MFC concurrently encodes those driving the other task. The same dichotomy was observed in the lateral frontal cortex, whereas the APC combined the rewards driving both tasks. The two frontal lobes thus divide for representing simultaneously two concurrent goals coordinated by the APC. The human frontal function seems limited to driving the pursuit of two concurrent goals simultaneously.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charron, Sylvain -- Koechlin, Etienne -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):360-3. doi: 10.1126/science.1183614.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale, Paris F-75654 Cedex 13, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20395509" target="_blank"〉PubMed〈/a〉

    Beschreibung: In everyday life, many people believe that two heads are better than one. Our ability to solve problems together appears to be fundamental to the current dominance and future survival of the human species. But are two heads really better than one? We addressed this question in the context of a collective low-level perceptual decision-making task. For two observers of nearly equal visual sensitivity, two heads were definitely better than one, provided they were given the opportunity to communicate freely, even in the absence of any feedback about decision outcomes. But for observers with very different visual sensitivities, two heads were actually worse than the better one. These seemingly discrepant patterns of group behavior can be explained by a model in which two heads are Bayes optimal under the assumption that individuals accurately communicate their level of confidence on every trial.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3371582/" 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/PMC3371582/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bahrami, Bahador -- Olsen, Karsten -- Latham, Peter E -- Roepstorff, Andreas -- Rees, Geraint -- Frith, Chris D -- 082334/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1081-5. doi: 10.1126/science.1185718.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University College London Institute of Cognitive Neuroscience, University College London, Alexandra House, 17 Queen Square, London WC1N 3AR, UK. bbahrami@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20798320" target="_blank"〉PubMed〈/a〉

    Thought for food: imagined consumption reduces actual consumption (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-12-15
    Beschreibung: The consumption of a food typically leads to a decrease in its subsequent intake through habituation--a decrease in one's responsiveness to the food and motivation to obtain it. We demonstrated that habituation to a food item can occur even when its consumption is merely imagined. Five experiments showed that people who repeatedly imagined eating a food (such as cheese) many times subsequently consumed less of the imagined food than did people who repeatedly imagined eating that food fewer times, imagined eating a different food (such as candy), or did not imagine eating a food. They did so because they desired to eat it less, not because they considered it less palatable. These results suggest that mental representation alone can engender habituation to a stimulus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morewedge, Carey K -- Huh, Young Eun -- Vosgerau, Joachim -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1530-3. doi: 10.1126/science.1195701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Social and Decision Sciences, Porter Hall 208, Carnegie Mellon University, Pittsburgh, PA, USA. morewedge@cmu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148388" target="_blank"〉PubMed〈/a〉

    Following the crowd: brain substrates of long-term memory conformity (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-02
    Beschreibung: Human memory is strikingly susceptible to social influences, yet we know little about the underlying mechanisms. We examined how socially induced memory errors are generated in the brain by studying the memory of individuals exposed to recollections of others. Participants exhibited a strong tendency to conform to erroneous recollections of the group, producing both long-lasting and temporary errors, even when their initial memory was strong and accurate. Functional brain imaging revealed that social influence modified the neuronal representation of memory. Specifically, a particular brain signature of enhanced amygdala activity and enhanced amygdala-hippocampus connectivity predicted long-lasting but not temporary memory alterations. Our findings reveal how social manipulation can alter memory and extend the known functions of the amygdala to encompass socially mediated memory distortions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3284232/" 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/PMC3284232/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edelson, Micah -- Sharot, Tali -- Dolan, Raymond J -- Dudai, Yadin -- 078865/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):108-11. doi: 10.1126/science.1203557.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Weizmann Institute of Science, Israel. micah.edelson@weizmann.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21719681" target="_blank"〉PubMed〈/a〉

    The growth factor progranulin binds to TNF receptors and is therapeutic against inflammatory arthritis in mice (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-03-12
    Beschreibung: The growth factor progranulin (PGRN) has been implicated in embryonic development, tissue repair, tumorigenesis, and inflammation, but its receptors remain unidentified. We report that PGRN bound directly to tumor necrosis factor receptors (TNFRs) and disturbed the TNFalpha-TNFR interaction. PGRN-deficient mice were susceptible to collagen-induced arthritis, and administration of PGRN reversed inflammatory arthritis. Atsttrin, an engineered protein composed of three PGRN fragments, exhibited selective TNFR binding. PGRN and Atsttrin prevented inflammation in multiple arthritis mouse models and inhibited TNFalpha-activated intracellular signaling. Collectively, these findings demonstrate that PGRN is a ligand of TNFR, an antagonist of TNFalpha signaling, and plays a critical role in the pathogenesis of inflammatory arthritis in mice. They also suggest new potential therapeutic interventions for various TNFalpha-mediated pathologies and conditions, including rheumatoid arthritis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3104397/" 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/PMC3104397/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Wei -- Lu, Yi -- Tian, Qing-Yun -- Zhang, Yan -- Guo, Feng-Jin -- Liu, Guang-Yi -- Syed, Nabeel Muzaffar -- Lai, Yongjie -- Lin, Edward Alan -- Kong, Li -- Su, Jeffrey -- Yin, Fangfang -- Ding, Ai-Hao -- Zanin-Zhorov, Alexandra -- Dustin, Michael L -- Tao, Jian -- Craft, Joseph -- Yin, Zhinan -- Feng, Jian Q -- Abramson, Steven B -- Yu, Xiu-Ping -- Liu, Chuan-ju -- AI43542/AI/NIAID NIH HHS/ -- AR040072/AR/NIAMS NIH HHS/ -- AR050620/AR/NIAMS NIH HHS/ -- AR053210/AR/NIAMS NIH HHS/ -- GM061710/GM/NIGMS NIH HHS/ -- R01 AI030165/AI/NIAID NIH HHS/ -- R01 AI030165-20/AI/NIAID NIH HHS/ -- R01 GM061710/GM/NIGMS NIH HHS/ -- R01 GM061710-08/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Apr 22;332(6028):478-84. doi: 10.1126/science.1199214.

    Widespread RNA and DNA sequence differences in the human transcriptome (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-05-21
    Beschreibung: The transmission of information from DNA to RNA is a critical process. We compared RNA sequences from human B cells of 27 individuals to the corresponding DNA sequences from the same individuals and uncovered more than 10,000 exonic sites where the RNA sequences do not match that of the DNA. All 12 possible categories of discordances were observed. These differences were nonrandom as many sites were found in multiple individuals and in different cell types, including primary skin cells and brain tissues. Using mass spectrometry, we detected peptides that are translated from the discordant RNA sequences and thus do not correspond exactly to the DNA sequences. These widespread RNA-DNA differences in the human transcriptome provide a yet unexplored aspect of genome variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3204392/" 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/PMC3204392/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Mingyao -- Wang, Isabel X -- Li, Yun -- Bruzel, Alan -- Richards, Allison L -- Toung, Jonathan M -- Cheung, Vivian G -- R01 HG005854/HG/NHGRI NIH HHS/ -- R01 HG005854-01/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):53-8. doi: 10.1126/science.1207018.

    Differences between tight and loose cultures: a 33-nation study (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-05-28
    Beschreibung: With data from 33 nations, we illustrate the differences between cultures that are tight (have many strong norms and a low tolerance of deviant behavior) versus loose (have weak social norms and a high tolerance of deviant behavior). Tightness-looseness is part of a complex, loosely integrated multilevel system that comprises distal ecological and historical threats (e.g., high population density, resource scarcity, a history of territorial conflict, and disease and environmental threats), broad versus narrow socialization in societal institutions (e.g., autocracy, media regulations), the strength of everyday recurring situations, and micro-level psychological affordances (e.g., prevention self-guides, high regulatory strength, need for structure). This research advances knowledge that can foster cross-cultural understanding in a world of increasing global interdependence and has implications for modeling cultural change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelfand, Michele J -- Raver, Jana L -- Nishii, Lisa -- Leslie, Lisa M -- Lun, Janetta -- Lim, Beng Chong -- Duan, Lili -- Almaliach, Assaf -- Ang, Soon -- Arnadottir, Jakobina -- Aycan, Zeynep -- Boehnke, Klaus -- Boski, Pawel -- Cabecinhas, Rosa -- Chan, Darius -- Chhokar, Jagdeep -- D'Amato, Alessia -- Ferrer, Montse -- Fischlmayr, Iris C -- Fischer, Ronald -- Fulop, Marta -- Georgas, James -- Kashima, Emiko S -- Kashima, Yoshishima -- Kim, Kibum -- Lempereur, Alain -- Marquez, Patricia -- Othman, Rozhan -- Overlaet, Bert -- Panagiotopoulou, Penny -- Peltzer, Karl -- Perez-Florizno, Lorena R -- Ponomarenko, Larisa -- Realo, Anu -- Schei, Vidar -- Schmitt, Manfred -- Smith, Peter B -- Soomro, Nazar -- Szabo, Erna -- Taveesin, Nalinee -- Toyama, Midori -- Van de Vliert, Evert -- Vohra, Naharika -- Ward, Colleen -- Yamaguchi, Susumu -- New York, N.Y. -- Science. 2011 May 27;332(6033):1100-4. doi: 10.1126/science.1197754.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Maryland, College Park, MD 20742, USA. mgelfand@psyc.umd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21617077" target="_blank"〉PubMed〈/a〉

    Human tears contain a chemosignal (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-01-08
    Beschreibung: Emotional tearing is a poorly understood behavior that is considered uniquely human. In mice, tears serve as a chemosignal. We therefore hypothesized that human tears may similarly serve a chemosignaling function. We found that merely sniffing negative-emotion-related odorless tears obtained from women donors induced reductions in sexual appeal attributed by men to pictures of women's faces. Moreover, after sniffing such tears, men experienced reduced self-rated sexual arousal, reduced physiological measures of arousal, and reduced levels of testosterone. Finally, functional magnetic resonance imaging revealed that sniffing women's tears selectively reduced activity in brain substrates of sexual arousal in men.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelstein, Shani -- Yeshurun, Yaara -- Rozenkrantz, Liron -- Shushan, Sagit -- Frumin, Idan -- Roth, Yehudah -- Sobel, Noam -- New York, N.Y. -- Science. 2011 Jan 14;331(6014):226-30. doi: 10.1126/science.1198331.

    Effects of working-memory training on striatal dopamine release (2011)

    Publikationsdatum: 2011-08-06
    Beschreibung: Updating of working memory has been associated with striato-frontal brain regions and phasic dopaminergic neurotransmission. We assessed raclopride binding to striatal dopamine (DA) D2 receptors during a letter-updating task and a control condition before and after 5 weeks of updating training. Results showed that updating affected DA activity before training and that training further increased striatal DA release during updating. These findings highlight the pivotal role of transient neural processes associated with D2 receptor activity in working memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Backman, Lars -- Nyberg, Lars -- Soveri, Anna -- Johansson, Jarkko -- Andersson, Micael -- Dahlin, Erika -- Neely, Anna S -- Virta, Jere -- Laine, Matti -- Rinne, Juha O -- New York, N.Y. -- Science. 2011 Aug 5;333(6043):718. doi: 10.1126/science.1204978.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Aging Research Center, Karolinska Institute, 171 77 Stockholm, Sweden. lars.backman.1@ki.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21817043" target="_blank"〉PubMed〈/a〉

    The genetic landscape of the childhood cancer medulloblastoma (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-12-18
    Beschreibung: Medulloblastoma (MB) is the most common malignant brain tumor of children. To identify the genetic alterations in this tumor type, we searched for copy number alterations using high-density microarrays and sequenced all known protein-coding genes and microRNA genes using Sanger sequencing in a set of 22 MBs. We found that, on average, each tumor had 11 gene alterations, fewer by a factor of 5 to 10 than in the adult solid tumors that have been sequenced to date. In addition to alterations in the Hedgehog and Wnt pathways, our analysis led to the discovery of genes not previously known to be altered in MBs. Most notably, inactivating mutations of the histone-lysine N-methyltransferase genes MLL2 or MLL3 were identified in 16% of MB patients. These results demonstrate key differences between the genetic landscapes of adult and childhood cancers, highlight dysregulation of developmental pathways as an important mechanism underlying MBs, and identify a role for a specific type of histone methylation in human tumorigenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3110744/" 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/PMC3110744/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, D Williams -- Li, Meng -- Zhang, Xiaosong -- Jones, Sian -- Leary, Rebecca J -- Lin, Jimmy Cheng-Ho -- Boca, Simina M -- Carter, Hannah -- Samayoa, Josue -- Bettegowda, Chetan -- Gallia, Gary L -- Jallo, George I -- Binder, Zev A -- Nikolsky, Yuri -- Hartigan, James -- Smith, Doug R -- Gerhard, Daniela S -- Fults, Daniel W -- VandenBerg, Scott -- Berger, Mitchel S -- Marie, Suely Kazue Nagahashi -- Shinjo, Sueli Mieko Oba -- Clara, Carlos -- Phillips, Peter C -- Minturn, Jane E -- Biegel, Jaclyn A -- Judkins, Alexander R -- Resnick, Adam C -- Storm, Phillip B -- Curran, Tom -- He, Yiping -- Rasheed, B Ahmed -- Friedman, Henry S -- Keir, Stephen T -- McLendon, Roger -- Northcott, Paul A -- Taylor, Michael D -- Burger, Peter C -- Riggins, Gregory J -- Karchin, Rachel -- Parmigiani, Giovanni -- Bigner, Darell D -- Yan, Hai -- Papadopoulos, Nick -- Vogelstein, Bert -- Kinzler, Kenneth W -- Velculescu, Victor E -- CA057345/CA/NCI NIH HHS/ -- CA096832/CA/NCI NIH HHS/ -- CA118822/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA135877/CA/NCI NIH HHS/ -- GM074906-01A1/GM/NIGMS NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- P01 CA096832/CA/NCI NIH HHS/ -- P01 CA096832-03/CA/NCI NIH HHS/ -- R01 CA108622/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-05/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-20/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):435-9. doi: 10.1126/science.1198056.

    Attention but not awareness modulates the BOLD signal in the human V1 during binocular suppression (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-11-15
    Beschreibung: Although recent psychophysical studies indicate that visual awareness and top-down attention are two distinct processes, it is not clear how they are neurally dissociated in the visual system. Using a two-by-two factorial functional magnetic resonance imaging design with binocular suppression, we found that the visibility or invisibility of a visual target led to only nonsignificant blood oxygenation level-dependent (BOLD) effects in the human primary visual cortex (V1). Directing attention toward and away from the target had much larger and robust effects across all study participants. The difference in the lower-level limit of BOLD activation between attention and awareness illustrates dissociated neural correlates of the two processes. Our results agree with previously reported V1 BOLD effects on attention, while they invite a reconsideration of the functional role of V1 in visual awareness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watanabe, Masataka -- Cheng, Kang -- Murayama, Yusuke -- Ueno, Kenichi -- Asamizuya, Takeshi -- Tanaka, Keiji -- Logothetis, Nikos -- New York, N.Y. -- Science. 2011 Nov 11;334(6057):829-31. doi: 10.1126/science.1203161.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Engineering, University of Tokyo, Tokyo, Japan. watanabe@tuebingen.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22076381" target="_blank"〉PubMed〈/a〉

    Perceptual learning incepted by decoded fMRI neurofeedback without stimulus presentation (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-12-14
    Beschreibung: It is controversial whether the adult primate early visual cortex is sufficiently plastic to cause visual perceptual learning (VPL). The controversy occurs partially because most VPL studies have examined correlations between behavioral and neural activity changes rather than cause-and-effect relationships. With an online-feedback method that uses decoded functional magnetic resonance imaging (fMRI) signals, we induced activity patterns only in early visual cortex corresponding to an orientation without stimulus presentation or participants' awareness of what was to be learned. The induced activation caused VPL specific to the orientation. These results suggest that early visual areas are so plastic that mere inductions of activity patterns are sufficient to cause VPL. This technique can induce plasticity in a highly selective manner, potentially leading to powerful training and rehabilitative protocols.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3297423/" 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/PMC3297423/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, Kazuhisa -- Watanabe, Takeo -- Sasaki, Yuka -- Kawato, Mitsuo -- R01 AG031941/AG/NIA NIH HHS/ -- R01 AG031941-04/AG/NIA NIH HHS/ -- R01 EY015980/EY/NEI NIH HHS/ -- R01 EY015980-04A2/EY/NEI NIH HHS/ -- R01 EY015980-05/EY/NEI NIH HHS/ -- R01 EY015980-06/EY/NEI NIH HHS/ -- R01 EY015980-07/EY/NEI NIH HHS/ -- R01 EY015980-08/EY/NEI NIH HHS/ -- R01 MH091801/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2011 Dec 9;334(6061):1413-5. doi: 10.1126/science.1212003.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Advanced Telecommunications Research Institute International Computational Neuroscience Laboratories, Keihanna Science City, Kyoto 619-0288, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22158821" target="_blank"〉PubMed〈/a〉

    Human voice recognition depends on language ability (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-30
    Beschreibung: The ability to recognize people by their voice is an important social behavior. Individuals differ in how they pronounce words, and listeners may take advantage of language-specific knowledge of speech phonology to facilitate recognizing voices. Impaired phonological processing is characteristic of dyslexia and thought to be a basis for difficulty in learning to read. We tested voice-recognition abilities of dyslexic and control listeners for voices speaking listeners' native language or an unfamiliar language. Individuals with dyslexia exhibited impaired voice-recognition abilities compared with controls only for voices speaking their native language. These results demonstrate the importance of linguistic representations for voice recognition. Humans appear to identify voices by making comparisons between talkers' pronunciations of words and listeners' stored abstract representations of the sounds in those words.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4242590/" 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/PMC4242590/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perrachione, Tyler K -- Del Tufo, Stephanie N -- Gabrieli, John D E -- UL1 RR025758/RR/NCRR NIH HHS/ -- UL1RR025758/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2011 Jul 29;333(6042):595. doi: 10.1126/science.1207327.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA. tkp@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21798942" target="_blank"〉PubMed〈/a〉

    Coping with chaos: how disordered contexts promote stereotyping and discrimination (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-04-09
    Beschreibung: Being the victim of discrimination can have serious negative health- and quality-of-life-related consequences. Yet, could being discriminated against depend on such seemingly trivial matters as garbage on the streets? In this study, we show, in two field experiments, that disordered contexts (such as litter or a broken-up sidewalk and an abandoned bicycle) indeed promote stereotyping and discrimination in real-world situations and, in three lab experiments, that it is a heightened need for structure that mediates these effects (number of subjects: between 40 and 70 per experiment). These findings considerably advance our knowledge of the impact of the physical environment on stereotyping and discrimination and have clear policy implications: Diagnose environmental disorder early and intervene immediately.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stapel, Diederik A -- Lindenberg, Siegwart -- New York, N.Y. -- Science. 2011 Apr 8;332(6026):251-3. doi: 10.1126/science.1201068.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tilburg Institute for Behavioral Economics Research, Tilburg University, Post Office Box 90153, 5000 LE Tilburg, Netherlands. d.a.stapel@uvt.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21474762" target="_blank"〉PubMed〈/a〉

    No evidence of murine-like gammaretroviruses in CFS patients previously identified as XMRV-infected (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-06-02
    Beschreibung: Members of the gammaretroviruses--such as murine leukemia viruses (MLVs), most notably XMRV [xenotropic murine leukemia virus (X-MLV)-related virus--have been reported to be present in the blood of patients with chronic fatigue syndrome (CFS). We evaluated blood samples from 61 patients with CFS from a single clinical practice, 43 of whom had previously been identified as XMRV-positive. Our analysis included polymerase chain reaction and reverse transcription polymerase chain reaction procedures for detection of viral nucleic acids and assays for detection of infectious virus and virus-specific antibodies. We found no evidence of XMRV or other MLVs in these blood samples. In addition, we found that these gammaretroviruses were strongly (X-MLV) or partially (XMRV) susceptible to inactivation by sera from CFS patients and healthy controls, which suggested that establishment of a successful MLV infection in humans would be unlikely. Consistent with previous reports, we detected MLV sequences in commercial laboratory reagents. Our results indicate that previous evidence linking XMRV and MLVs to CFS is likely attributable to laboratory contamination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knox, Konstance -- Carrigan, Donald -- Simmons, Graham -- Teque, Fernando -- Zhou, Yanchen -- Hackett, John Jr -- Qiu, Xiaoxing -- Luk, Ka-Cheung -- Schochetman, Gerald -- Knox, Allyn -- Kogelnik, Andreas M -- Levy, Jay A -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):94-7. doi: 10.1126/science.1204963.

    Beschreibung: In 1990, shotguns and M-16s were adopted into Enga warfare, setting off some 15 years of devastation as youths (~17 to 28) took charge of interclan warfare. In response, people called on elder leaders to adapt customary institutions to restore peace; subsequently, war deaths and the frequency of war declined radically. Data from precolonial warfare, 501 recent wars, and 129 customary court sessions allow us to consider (i) the principles and values behind customary institutions for peace, (ii) their effectiveness, (iii) how they interact with and compare to state institutions of today, and (iv) how such institutions might have shaped our human behavioral repertoire to make life in state societies possible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wiessner, Polly -- Pupu, Nitze -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1651-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Utah, Salt Lake City, UT 84112, USA. wiessner@soft-link.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019648" target="_blank"〉PubMed〈/a〉

    Niche and neutral effects of acquired immunity permit coexistence of pneumococcal serotypes (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-03-03
    Beschreibung: Over 90 capsular serotypes of Streptococcus pneumoniae, a common nasopharyngeal colonizer and major cause of pneumonia, bacteremia, and meningitis, are known. It is unclear why some serotypes can persist at all: They are more easily cleared from carriage and compete poorly in vivo. Serotype-specific immune responses, which could promote diversity in principle, are weak enough to allow repeated colonizations by the same type. We show that weak serotype-specific immunity and an acquired response not specific to the capsule can together reproduce observed diversity. Serotype-specific immunity stabilizes competition, and acquired immunity to noncapsular antigens reduces fitness differences. Our model can be used to explain the effects of pneumococcal vaccination and indicates general factors that regulate the diversity of pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3341938/" 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/PMC3341938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cobey, Sarah -- Lipsitch, Marc -- 1F32GM097997/GM/NIGMS NIH HHS/ -- 5R01AI048935/AI/NIAID NIH HHS/ -- F32 GM097997/GM/NIGMS NIH HHS/ -- U54 GM088558/GM/NIGMS NIH HHS/ -- U54 GM088558-02/GM/NIGMS NIH HHS/ -- U54GM088558/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 16;335(6074):1376-80. doi: 10.1126/science.1215947.

    Analytic thinking promotes religious disbelief (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-04-28
    Beschreibung: Scientific interest in the cognitive underpinnings of religious belief has grown in recent years. However, to date, little experimental research has focused on the cognitive processes that may promote religious disbelief. The present studies apply a dual-process model of cognitive processing to this problem, testing the hypothesis that analytic processing promotes religious disbelief. Individual differences in the tendency to analytically override initially flawed intuitions in reasoning were associated with increased religious disbelief. Four additional experiments provided evidence of causation, as subtle manipulations known to trigger analytic processing also encouraged religious disbelief. Combined, these studies indicate that analytic processing is one factor (presumably among several) that promotes religious disbelief. Although these findings do not speak directly to conversations about the inherent rationality, value, or truth of religious beliefs, they illuminate one cognitive factor that may influence such discussions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gervais, Will M -- Norenzayan, Ara -- New York, N.Y. -- Science. 2012 Apr 27;336(6080):493-6. doi: 10.1126/science.1215647.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of British Columbia, Vancouver, BC, Canada. will@psych.ubc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22539725" target="_blank"〉PubMed〈/a〉

    Preference by association: how memory mechanisms in the hippocampus bias decisions (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-10-16
    Beschreibung: Every day people make new choices between alternatives that they have never directly experienced. Yet, such decisions are often made rapidly and confidently. Here, we show that the hippocampus, traditionally known for its role in building long-term declarative memories, enables the spread of value across memories, thereby guiding decisions between new choice options. Using functional brain imaging in humans, we discovered that giving people monetary rewards led to activation of a preestablished network of memories, spreading the positive value of reward to nonrewarded items stored in memory. Later, people were biased to choose these nonrewarded items. This decision bias was predicted by activity in the hippocampus, reactivation of associated memories, and connectivity between memory and reward regions in the brain. These findings explain how choices among new alternatives emerge automatically from the associative mechanisms by which the brain builds memories. Further, our findings demonstrate a previously unknown role for the hippocampus in value-based decisions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wimmer, G Elliott -- Shohamy, Daphna -- R03-DA026957/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 12;338(6104):270-3. doi: 10.1126/science.1223252.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Columbia University, New York, NY 10027, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23066083" target="_blank"〉PubMed〈/a〉

    Beschreibung: We document that China's One-Child Policy (OCP), one of the most radical approaches to limiting population growth, has produced significantly less trusting, less trustworthy, more risk-averse, less competitive, more pessimistic, and less conscientious individuals. Our data were collected from economics experiments conducted with 421 individuals born just before and just after the OCP's introduction in 1979. Surveys to elicit personality traits were also used. We used the exogenous imposition of the OCP to identify the causal impact of being an only child, net of family background effects. The OCP thus has significant ramifications for Chinese society.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cameron, L -- Erkal, N -- Gangadharan, L -- Meng, X -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):953-7. doi: 10.1126/science.1230221.

    Neural mechanisms of foraging (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-04-12
    Beschreibung: Behavioral economic studies involving limited numbers of choices have provided key insights into neural decision-making mechanisms. By contrast, animals' foraging choices arise in the context of sequences of encounters with prey or food. On each encounter, the animal chooses whether to engage or, if the environment is sufficiently rich, to search elsewhere. The cost of foraging is also critical. We demonstrate that humans can alternate between two modes of choice, comparative decision-making and foraging, depending on distinct neural mechanisms in ventromedial prefrontal cortex (vmPFC) and anterior cingulate cortex (ACC) using distinct reference frames; in ACC, choice variables are represented in invariant reference to foraging or searching for alternatives. Whereas vmPFC encodes values of specific well-defined options, ACC encodes the average value of the foraging environment and cost of foraging.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440844/" 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/PMC3440844/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolling, Nils -- Behrens, Timothy E J -- Mars, Rogier B -- Rushworth, Matthew F S -- 088312/Wellcome Trust/United Kingdom -- 089280/Wellcome Trust/United Kingdom -- G0600994/Medical Research Council/United Kingdom -- G0600994(79113)/Medical Research Council/United Kingdom -- G0700399/Medical Research Council/United Kingdom -- G0802146/Medical Research Council/United Kingdom -- G0802146(89549)/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Apr 6;336(6077):95-8. doi: 10.1126/science.1216930.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Psychology, University of Oxford, Oxford OX1 3UD, UK. nils.kolling@psy.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22491854" target="_blank"〉PubMed〈/a〉

    Global epigenomic reconfiguration during mammalian brain development (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-07-06
    Beschreibung: DNA methylation is implicated in mammalian brain development and plasticity underlying learning and memory. We report the genome-wide composition, patterning, cell specificity, and dynamics of DNA methylation at single-base resolution in human and mouse frontal cortex throughout their lifespan. Widespread methylome reconfiguration occurs during fetal to young adult development, coincident with synaptogenesis. During this period, highly conserved non-CG methylation (mCH) accumulates in neurons, but not glia, to become the dominant form of methylation in the human neuronal genome. Moreover, we found an mCH signature that identifies genes escaping X-chromosome inactivation. Last, whole-genome single-base resolution 5-hydroxymethylcytosine (hmC) maps revealed that hmC marks fetal brain cell genomes at putative regulatory regions that are CG-demethylated and activated in the adult brain and that CG demethylation at these hmC-poised loci depends on Tet2 activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3785061/" 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/PMC3785061/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, Ryan -- Mukamel, Eran A -- Nery, Joseph R -- Urich, Mark -- Puddifoot, Clare A -- Johnson, Nicholas D -- Lucero, Jacinta -- Huang, Yun -- Dwork, Andrew J -- Schultz, Matthew D -- Yu, Miao -- Tonti-Filippini, Julian -- Heyn, Holger -- Hu, Shijun -- Wu, Joseph C -- Rao, Anjana -- Esteller, Manel -- He, Chuan -- Haghighi, Fatemeh G -- Sejnowski, Terrence J -- Behrens, M Margarita -- Ecker, Joseph R -- AI44432/AI/NIAID NIH HHS/ -- CA151535/CA/NCI NIH HHS/ -- HD065812/HD/NICHD NIH HHS/ -- HG006827/HG/NHGRI NIH HHS/ -- K99NS080911/NS/NINDS NIH HHS/ -- MH094670/MH/NIMH NIH HHS/ -- R01 AI044432/AI/NIAID NIH HHS/ -- R01 CA151535/CA/NCI NIH HHS/ -- R01 HD065812/HD/NICHD NIH HHS/ -- R01 HG006827/HG/NHGRI NIH HHS/ -- R01 MH094670/MH/NIMH NIH HHS/ -- R01 MH094774/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):1237905. doi: 10.1126/science.1237905.

    Poverty impedes cognitive function (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-08-31
    Beschreibung: The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mani, Anandi -- Mullainathan, Sendhil -- Shafir, Eldar -- Zhao, Jiaying -- New York, N.Y. -- Science. 2013 Aug 30;341(6149):976-80. doi: 10.1126/science.1238041.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, University of Warwick, Coventry, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23990553" target="_blank"〉PubMed〈/a〉

    Protection against malaria by intravenous immunization with a nonreplicating sporozoite vaccine (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-08-10
    Beschreibung: Consistent, high-level, vaccine-induced protection against human malaria has only been achieved by inoculation of Plasmodium falciparum (Pf) sporozoites (SPZ) by mosquito bites. We report that the PfSPZ Vaccine--composed of attenuated, aseptic, purified, cryopreserved PfSPZ--was safe and well tolerated when administered four to six times intravenously (IV) to 40 adults. Zero of six subjects receiving five doses and three of nine subjects receiving four doses of 1.35 x 10(5) PfSPZ Vaccine and five of six nonvaccinated controls developed malaria after controlled human malaria infection (P = 0.015 in the five-dose group and P = 0.028 for overall, both versus controls). PfSPZ-specific antibody and T cell responses were dose-dependent. These data indicate that there is a dose-dependent immunological threshold for establishing high-level protection against malaria that can be achieved with IV administration of a vaccine that is safe and meets regulatory standards.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seder, Robert A -- Chang, Lee-Jah -- Enama, Mary E -- Zephir, Kathryn L -- Sarwar, Uzma N -- Gordon, Ingelise J -- Holman, LaSonji A -- James, Eric R -- Billingsley, Peter F -- Gunasekera, Anusha -- Richman, Adam -- Chakravarty, Sumana -- Manoj, Anita -- Velmurugan, Soundarapandian -- Li, MingLin -- Ruben, Adam J -- Li, Tao -- Eappen, Abraham G -- Stafford, Richard E -- Plummer, Sarah H -- Hendel, Cynthia S -- Novik, Laura -- Costner, Pamela J M -- Mendoza, Floreliz H -- Saunders, Jamie G -- Nason, Martha C -- Richardson, Jason H -- Murphy, Jittawadee -- Davidson, Silas A -- Richie, Thomas L -- Sedegah, Martha -- Sutamihardja, Awalludin -- Fahle, Gary A -- Lyke, Kirsten E -- Laurens, Matthew B -- Roederer, Mario -- Tewari, Kavita -- Epstein, Judith E -- Sim, B Kim Lee -- Ledgerwood, Julie E -- Graham, Barney S -- Hoffman, Stephen L -- VRC 312 Study Team -- 3R44AI055229-06S1/AI/NIAID NIH HHS/ -- 4R44AI055229-08/AI/NIAID NIH HHS/ -- 5R44AI058499-05/AI/NIAID NIH HHS/ -- N01-AI-40096/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1359-65. doi: 10.1126/science.1241800.

    Neural decoding of visual imagery during sleep (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-04-06
    Beschreibung: Visual imagery during sleep has long been a topic of persistent speculation, but its private nature has hampered objective analysis. Here we present a neural decoding approach in which machine-learning models predict the contents of visual imagery during the sleep-onset period, given measured brain activity, by discovering links between human functional magnetic resonance imaging patterns and verbal reports with the assistance of lexical and image databases. Decoding models trained on stimulus-induced brain activity in visual cortical areas showed accurate classification, detection, and identification of contents. Our findings demonstrate that specific visual experience during sleep is represented by brain activity patterns shared by stimulus perception, providing a means to uncover subjective contents of dreaming using objective neural measurement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horikawa, T -- Tamaki, M -- Miyawaki, Y -- Kamitani, Y -- New York, N.Y. -- Science. 2013 May 3;340(6132):639-42. doi: 10.1126/science.1234330.

    Tetrahydrobiopterin biosynthesis as an off-target of sulfa drugs (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-05-25
    Beschreibung: The introduction of sulfa drugs for the chemotherapy of bacterial infections in 1935 revolutionized medicine. Although their mechanism of action is understood, the molecular bases for most of their side effects remain obscure. Here, we report that sulfamethoxazole and other sulfa drugs interfere with tetrahydrobiopterin biosynthesis through inhibition of sepiapterin reductase. Crystal structures of sepiapterin reductase with bound sulfa drugs reveal how structurally diverse sulfa drugs achieve specific inhibition of the enzyme. The effect of sulfa drugs on tetrahydrobiopterin-dependent neurotransmitter biosynthesis in cell-based assays provides a rationale for some of their central nervous system-related side effects, particularly in high-dose sulfamethoxazole therapy of Pneumocystis pneumonia. Our findings reveal an unexpected aspect of the pharmacology of sulfa drugs and might translate into their improved medical use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haruki, Hirohito -- Pedersen, Miriam Gronlund -- Gorska, Katarzyna Irena -- Pojer, Florence -- Johnsson, Kai -- New York, N.Y. -- Science. 2013 May 24;340(6135):987-91. doi: 10.1126/science.1232972.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉EPFL, Institute of Chemical Sciences and Engineering, Institute of Bioengineering, National Centre of Competence in Research in Chemical Biology, 1015 Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23704574" target="_blank"〉PubMed〈/a〉

    High coverage of ART associated with decline in risk of HIV acquisition in rural KwaZulu-Natal, South Africa (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-02-23
    Beschreibung: The landmark HIV Prevention Trials Network (HPTN) 052 trial in HIV-discordant couples demonstrated unequivocally that treatment with antiretroviral therapy (ART) substantially lowers the probability of HIV transmission to the HIV-uninfected partner. However, it has been vigorously debated whether substantial population-level reductions in the rate of new HIV infections could be achieved in "real-world" sub-Saharan African settings where stable, cohabiting couples are often not the norm and where considerable operational challenges exist to the successful and sustainable delivery of treatment and care to large numbers of patients. We used data from one of Africa's largest population-based prospective cohort studies (in rural KwaZulu-Natal, South Africa) to follow up a total of 16,667 individuals who were HIV-uninfected at baseline, observing individual HIV seroconversions over the period 2004 to 2011. Holding other key HIV risk factors constant, individual HIV acquisition risk declined significantly with increasing ART coverage in the surrounding local community. For example, an HIV-uninfected individual living in a community with high ART coverage (30 to 40% of all HIV-infected individuals on ART) was 38% less likely to acquire HIV than someone living in a community where ART coverage was low (〈10% of all HIV-infected individuals on ART).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4255272/" 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/PMC4255272/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanser, Frank -- Barnighausen, Till -- Grapsa, Erofili -- Zaidi, Jaffer -- Newell, Marie-Louise -- 082384/Z/07/Z/Wellcome Trust/United Kingdom -- 097410/Wellcome Trust/United Kingdom -- 1R01-HD058482-01/HD/NICHD NIH HHS/ -- R01 HD058482/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):966-71. doi: 10.1126/science.1228160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Africa Centre for Health and Population Studies, University of KwaZulu-Natal, South Africa. tanserf@africacentre.ac.za〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430656" target="_blank"〉PubMed〈/a〉

    Increases in adult life expectancy in rural South Africa: valuing the scale-up of HIV treatment (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-02-23
    Beschreibung: The scale-up of antiretroviral therapy (ART) is expected to raise adult life expectancy in populations with high HIV prevalence. Using data from a population cohort of over 101,000 individuals in rural KwaZulu-Natal, South Africa, we measured changes in adult life expectancy for 2000-2011. In 2003, the year before ART became available in the public-sector health system, adult life expectancy was 49.2 years; by 2011, adult life expectancy had increased to 60.5 years--an 11.3-year gain. Based on standard monetary valuation of life, the survival benefits of ART far outweigh the costs of providing treatment in this community. These gains in adult life expectancy signify the social value of ART and have implications for the investment decisions of individuals, governments, and donors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3860268/" 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/PMC3860268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bor, Jacob -- Herbst, Abraham J -- Newell, Marie-Louise -- Barnighausen, Till -- 097410/Wellcome Trust/United Kingdom -- 1R01MH083539-01/MH/NIMH NIH HHS/ -- R01 HD058482-01/HD/NICHD NIH HHS/ -- R01 MH083539/MH/NIMH NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):961-5. doi: 10.1126/science.1230413.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Africa Centre for Health and Population Studies, University of KwaZulu-Natal, Post Office Box 198, Mtubatuba, KwaZulu-Natal 3935, South Africa. jbor@hsph.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430655" target="_blank"〉PubMed〈/a〉

    Beschreibung: We measured the personalities, values, and preferences of more than 19,000 people who ranged in age from 18 to 68 and asked them to report how much they had changed in the past decade and/or to predict how much they would change in the next decade. Young people, middle-aged people, and older people all believed they had changed a lot in the past but would change relatively little in the future. People, it seems, regard the present as a watershed moment at which they have finally become the person they will be for the rest of their lives. This "end of history illusion" had practical consequences, leading people to overpay for future opportunities to indulge their current preferences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quoidbach, Jordi -- Gilbert, Daniel T -- Wilson, Timothy D -- P01 AG020166/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 4;339(6115):96-8. doi: 10.1126/science.1229294.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Fund for Scientific Research, Brussels, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23288539" target="_blank"〉PubMed〈/a〉

    Plasticity of the aging brain: new directions in cognitive neuroscience (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-11-02
    Beschreibung: Cognitive neuroscience has revealed aging of the human brain to be rich in reorganization and change. Neuroimaging results have recast our framework around cognitive aging from one of decline to one emphasizing plasticity. Current methods use neurostimulation approaches to manipulate brain function, providing a direct test of the ways that the brain differently contributes to task performance for younger and older adults. Emerging research into emotional, social, and motivational domains provides some evidence for preservation with age, suggesting potential avenues of plasticity, alongside additional evidence for reorganization. Thus, we begin to see that aging of the brain, amidst interrelated behavioral and biological changes, is as complex and idiosyncratic as the brain itself, qualitatively changing over the life span.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gutchess, Angela -- New York, N.Y. -- Science. 2014 Oct 31;346(6209):579-82. doi: 10.1126/science.1254604.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Volen National Center for Complex Systems, Brandeis University, Waltham, MA, USA.

    Neural mechanisms of object-based attention (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-04-26
    Beschreibung: How we attend to objects and their features that cannot be separated by location is not understood. We presented two temporally and spatially overlapping streams of objects, faces versus houses, and used magnetoencephalography and functional magnetic resonance imaging to separate neuronal responses to attended and unattended objects. Attention to faces versus houses enhanced the sensory responses in the fusiform face area (FFA) and parahippocampal place area (PPA), respectively. The increases in sensory responses were accompanied by induced gamma synchrony between the inferior frontal junction, IFJ, and either FFA or PPA, depending on which object was attended. The IFJ appeared to be the driver of the synchrony, as gamma phases were advanced by 20 ms in IFJ compared to FFA or PPA. Thus, the IFJ may direct the flow of visual processing during object-based attention, at least in part through coupled oscillations with specialized areas such as FFA and PPA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldauf, Daniel -- Desimone, Robert -- P30EY2621/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):424-7. doi: 10.1126/science.1247003.

    Antibodies to PfSEA-1 block parasite egress from RBCs and protect against malaria infection (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-05-24
    Beschreibung: Novel vaccines are urgently needed to reduce the burden of severe malaria. Using a differential whole-proteome screening method, we identified Plasmodium falciparum schizont egress antigen-1 (PfSEA-1), a 244-kilodalton parasite antigen expressed in schizont-infected red blood cells (RBCs). Antibodies to PfSEA-1 decreased parasite replication by arresting schizont rupture, and conditional disruption of PfSEA-1 resulted in a profound parasite replication defect. Vaccination of mice with recombinant Plasmodium berghei PbSEA-1 significantly reduced parasitemia and delayed mortality after lethal challenge with the Plasmodium berghei strain ANKA. Tanzanian children with antibodies to recombinant PfSEA-1A (rPfSEA-1A) did not experience severe malaria, and Kenyan adolescents and adults with antibodies to rPfSEA-1A had significantly lower parasite densities than individuals without these antibodies. By blocking schizont egress, PfSEA-1 may synergize with other vaccines targeting hepatocyte and RBC invasion.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184151/" 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/PMC4184151/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raj, Dipak K -- Nixon, Christian P -- Nixon, Christina E -- Dvorin, Jeffrey D -- DiPetrillo, Christen G -- Pond-Tor, Sunthorn -- Wu, Hai-Wei -- Jolly, Grant -- Pischel, Lauren -- Lu, Ailin -- Michelow, Ian C -- Cheng, Ling -- Conteh, Solomon -- McDonald, Emily A -- Absalon, Sabrina -- Holte, Sarah E -- Friedman, Jennifer F -- Fried, Michal -- Duffy, Patrick E -- Kurtis, Jonathan D -- 1K08AI100997-01A1/AI/NIAID NIH HHS/ -- DP2 AI112219/AI/NIAID NIH HHS/ -- DP2-AI112219/AI/NIAID NIH HHS/ -- K08 AI100997/AI/NIAID NIH HHS/ -- P20GM103421/GM/NIGMS NIH HHS/ -- P30 AI042853/AI/NIAID NIH HHS/ -- P30AI042853/AI/NIAID NIH HHS/ -- R01 AI102907/AI/NIAID NIH HHS/ -- R01-AI076353/AI/NIAID NIH HHS/ -- R01-AI102907/AI/NIAID NIH HHS/ -- R01-AI52059/AI/NIAID NIH HHS/ -- T32-DA013911/DA/NIDA NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 May 23;344(6186):871-7. doi: 10.1126/science.1254417.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for International Health Research, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence, RI 02903, USA. ; Division of Infectious Diseases, Boston Children's Hospital and Harvard Medical School, Boston, MA 02115, USA. ; Center for International Health Research, Rhode Island Hospital, The Warren Alpert Medical School of Brown University, Providence, RI 02903, USA.

    Human cognitive aging: corriger la fortune? (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-11-02
    Beschreibung: Human cognitive aging differs between and is malleable within individuals. In the absence of a strong genetic program, it is open to a host of hazards, such as vascular conditions, metabolic syndrome, and chronic stress, but also open to protective and enhancing factors, such as experience-dependent cognitive plasticity. Longitudinal studies suggest that leading an intellectually challenging, physically active, and socially engaged life may mitigate losses and consolidate gains. Interventions help to identify contexts and mechanisms of successful cognitive aging and give science and society a hint about what would be possible if conditions were different.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindenberger, Ulman -- New York, N.Y. -- Science. 2014 Oct 31;346(6209):572-8. doi: 10.1126/science.1254403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Lifespan Psychology, Max Planck Institute for Human Development, Lentzeallee 94, 14195 Berlin, Germany.

    Humans can discriminate more than 1 trillion olfactory stimuli (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-03-22
    Beschreibung: Humans can discriminate several million different colors and almost half a million different tones, but the number of discriminable olfactory stimuli remains unknown. The lay and scientific literature typically claims that humans can discriminate 10,000 odors, but this number has never been empirically validated. We determined the resolution of the human sense of smell by testing the capacity of humans to discriminate odor mixtures with varying numbers of shared components. On the basis of the results of psychophysical testing, we calculated that humans can discriminate at least 1 trillion olfactory stimuli. This is far more than previous estimates of distinguishable olfactory stimuli. It demonstrates that the human olfactory system, with its hundreds of different olfactory receptors, far outperforms the other senses in the number of physically different stimuli it can discriminate.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4483192/" 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/PMC4483192/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushdid, C -- Magnasco, M O -- Vosshall, L B -- Keller, A -- UL1 TR000043/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1370-2. doi: 10.1126/science.1249168.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Neurogenetics and Behavior, The Rockefeller University, 1230 York Avenue, Box 63, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653035" target="_blank"〉PubMed〈/a〉

    Beschreibung: 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.

    Publikationsdatum: 2016-05-13
    Beschreibung: 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

    [In Depth] El Niño's warmth devastating reefs worldwide (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publikationsdatum: 2016-04-01
    Beschreibung: 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.

    Beschreibung: 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

    Publikationsdatum: 2014-11-29
    Beschreibung: Two studies examined how U.S. presidents are forgotten. A total of 415 undergraduates in 1974, 1991, and 2009 recalled as many presidents as possible and attempted to place them in their correct ordinal positions. All showed roughly linear forgetting of the eight or nine presidents prior to the president holding office at the time, and recall of presidents without respect to ordinal position also showed a regular pattern of forgetting. Similar outcomes occurred with 497 adults (ages 18 to 69) tested in 2014. We fit forgetting functions to the data to predict when six relatively recent presidents will recede in memory to the level of most middle presidents (e.g., we predict that Truman will be forgotten to the same extent as McKinley by about 2040). These studies show that forgetting from collective memory can be studied empirically, as with forgetting in other forms of memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roediger, H L 3rd -- DeSoto, K A -- New York, N.Y. -- Science. 2014 Nov 28;346(6213):1106-9. doi: 10.1126/science.1259627.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Washington University, St. Louis, MO 63130, USA. roediger@wustl.edu. ; Department of Psychology, Washington University, St. Louis, MO 63130, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25430768" target="_blank"〉PubMed〈/a〉

    The cultural evolution of mind reading (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-06-21
    Beschreibung: It is not just a manner of speaking: "Mind reading," or working out what others are thinking and feeling, is markedly similar to print reading. Both of these distinctly human skills recover meaning from signs, depend on dedicated cortical areas, are subject to genetically heritable disorders, show cultural variation around a universal core, and regulate how people behave. But when it comes to development, the evidence is conflicting. Some studies show that, like learning to read print, learning to read minds is a long, hard process that depends on tuition. Others indicate that even very young, nonliterate infants are already capable of mind reading. Here, we propose a resolution to this conflict. We suggest that infants are equipped with neurocognitive mechanisms that yield accurate expectations about behavior ("automatic" or "implicit" mind reading), whereas "explicit" mind reading, like literacy, is a culturally inherited skill; it is passed from one generation to the next by verbal instruction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heyes, Cecilia M -- Frith, Chris D -- 091593/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Jun 20;344(6190):1243091. doi: 10.1126/science.1243091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉All Souls College and Department of Experimental Psychology, University of Oxford, Oxford OX1 4AL, UK. cecilia.heyes@all-souls.ox.ac.uk. ; Wellcome Trust Centre for Neuroimaging, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24948740" target="_blank"〉PubMed〈/a〉

    High-resolution genomic analysis of human mitochondrial RNA sequence variation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-04-26
    Beschreibung: Mutations in the mitochondrial genome are associated with multiple diseases and biological processes; however, little is known about the extent of sequence variation in the mitochondrial transcriptome. By ultra-deeply sequencing mitochondrial RNA (〉6000x) from the whole blood of ~1000 individuals from the CARTaGENE project, we identified remarkable levels of sequence variation within and across individuals, as well as sites that show consistent patterns of posttranscriptional modification. Using a genome-wide association study, we find that posttranscriptional modification of functionally important sites in mitochondrial transfer RNAs (tRNAs) is under strong genetic control, largely driven by a missense mutation in MRPP3 that explains ~22% of the variance. These results reveal a major nuclear genetic determinant of posttranscriptional modification in mitochondria and suggest that tRNA posttranscriptional modification may affect cellular energy production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodgkinson, Alan -- Idaghdour, Youssef -- Gbeha, Elias -- Grenier, Jean-Christophe -- Hip-Ki, Elodie -- Bruat, Vanessa -- Goulet, Jean-Philippe -- de Malliard, Thibault -- Awadalla, Philip -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):413-5. doi: 10.1126/science.1251110.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CHU Sainte-Justine Research Centre, Department of Pediatrics, Faculty of Medicine, Universite de Montreal, 3175 Chemin de la Cote-Sainte-Catherine, Montreal, Quebec H3T 1C5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763589" target="_blank"〉PubMed〈/a〉

    Morality in everyday life (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-09-13
    Beschreibung: The science of morality has drawn heavily on well-controlled but artificial laboratory settings. To study everyday morality, we repeatedly assessed moral or immoral acts and experiences in a large (N = 1252) sample using ecological momentary assessment. Moral experiences were surprisingly frequent and manifold. Liberals and conservatives emphasized somewhat different moral dimensions. Religious and nonreligious participants did not differ in the likelihood or quality of committed moral and immoral acts. Being the target of moral or immoral deeds had the strongest impact on happiness, whereas committing moral or immoral deeds had the strongest impact on sense of purpose. Analyses of daily dynamics revealed evidence for both moral contagion and moral licensing. In sum, morality science may benefit from a closer look at the antecedents, dynamics, and consequences of everyday moral experience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hofmann, Wilhelm -- Wisneski, Daniel C -- Brandt, Mark J -- Skitka, Linda J -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1340-3. doi: 10.1126/science.1251560.

    Beschreibung: To systematically investigate the impact of immune stimulation upon regulatory variant activity, we exposed primary monocytes from 432 healthy Europeans to interferon-gamma (IFN-gamma) or differing durations of lipopolysaccharide and mapped expression quantitative trait loci (eQTLs). More than half of cis-eQTLs identified, involving hundreds of genes and associated pathways, are detected specifically in stimulated monocytes. Induced innate immune activity reveals multiple master regulatory trans-eQTLs including the major histocompatibility complex (MHC), coding variants altering enzyme and receptor function, an IFN-beta cytokine network showing temporal specificity, and an interferon regulatory factor 2 (IRF2) transcription factor-modulated network. Induced eQTL are significantly enriched for genome-wide association study loci, identifying context-specific associations to putative causal genes including CARD9, ATM, and IRF8. Thus, applying pathophysiologically relevant immune stimuli assists resolution of functional genetic variants.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4064786/" 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/PMC4064786/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fairfax, Benjamin P -- Humburg, Peter -- Makino, Seiko -- Naranbhai, Vivek -- Wong, Daniel -- Lau, Evelyn -- Jostins, Luke -- Plant, Katharine -- Andrews, Robert -- McGee, Chris -- Knight, Julian C -- 074318/Wellcome Trust/United Kingdom -- 088891/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 281824/European Research Council/International -- 98082/Medical Research Council/United Kingdom -- G1001708/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1246949. doi: 10.1126/science.1246949.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, University of Oxford, Roosevelt Drive, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604202" target="_blank"〉PubMed〈/a〉

    Common genetic variants modulate pathogen-sensing responses in human dendritic cells (2014)
    American Association for the Advancement of Science (AAAS)
    Details

    Beschreibung: Little is known about how human genetic variation affects the responses to environmental stimuli in the context of complex diseases. Experimental and computational approaches were applied to determine the effects of genetic variation on the induction of pathogen-responsive genes in human dendritic cells. We identified 121 common genetic variants associated in cis with variation in expression responses to Escherichia coli lipopolysaccharide, influenza, or interferon-beta (IFN-beta). We localized and validated causal variants to binding sites of pathogen-activated STAT (signal transducer and activator of transcription) and IRF (IFN-regulatory factor) transcription factors. We also identified a common variant in IRF7 that is associated in trans with type I IFN induction in response to influenza infection. Our results reveal common alleles that explain interindividual variation in pathogen sensing and provide functional annotation for genetic variants that alter susceptibility to inflammatory diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4124741/" 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/PMC4124741/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Mark N -- Ye, Chun -- Villani, Alexandra-Chloe -- Raj, Towfique -- Li, Weibo -- Eisenhaure, Thomas M -- Imboywa, Selina H -- Chipendo, Portia I -- Ran, F Ann -- Slowikowski, Kamil -- Ward, Lucas D -- Raddassi, Khadir -- McCabe, Cristin -- Lee, Michelle H -- Frohlich, Irene Y -- Hafler, David A -- Kellis, Manolis -- Raychaudhuri, Soumya -- Zhang, Feng -- Stranger, Barbara E -- Benoist, Christophe O -- De Jager, Philip L -- Regev, Aviv -- Hacohen, Nir -- DP1 CA174427/CA/NCI NIH HHS/ -- DP1 MH100706/DP/NCCDPHP CDC HHS/ -- DP1 MH100706/MH/NIMH NIH HHS/ -- DP2 OD002230/OD/NIH HHS/ -- F32 AG043267/AG/NIA NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- P50 HG006193/HG/NHGRI NIH HHS/ -- R01 AI091568/AI/NIAID NIH HHS/ -- R01 AR063759/AR/NIAMS NIH HHS/ -- R01 DK097768/DK/NIDDK NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- RC2 GM093080/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- T32 HG002295/HG/NHGRI NIH HHS/ -- U19 AI082630/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1246980. doi: 10.1126/science.1246980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of Massachusetts Institute of Technology (MIT) and Harvard, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604203" target="_blank"〉PubMed〈/a〉
