    Aerosol-driven droplet concentrations dominate coverage and water of oceanic low-level clouds (2019)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2019
    Description: 〈p〉A lack of reliable estimates of cloud condensation nuclei (CCN) aerosols over oceans has severely limited our ability to quantify their effects on cloud properties and extent of cooling by reflecting solar radiation—a key uncertainty in anthropogenic climate forcing. We introduce a methodology for ascribing cloud properties to CCN and isolating the aerosol effects from meteorological effects. Its application showed that for a given meteorology, CCN explains three-fourths of the variability in the radiative cooling effect of clouds, mainly through affecting shallow cloud cover and water path. This reveals a much greater sensitivity of cloud radiative forcing to CCN than previously reported, which means too much cooling if incorporated into present climate models. This suggests the existence of compensating aerosol warming effects yet to be discovered, possibly through deep clouds.〈/p〉

    Pleistocene milestones on the out-of-Africa corridor at Gesher Benot Ya'aqov, israel (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-08-11
    Description: The Acheulean site of Gesher Benot Ya'aqov in the Dead Sea Rift of Israel documents hominin movements and technological development on a corridor between Africa and Eurasia. New age data place the site at 780,000 years ago (oxygen isotope stage 19), considerably older than previous estimates. The archaeological data from the site portray strong affinities with African stone tool traditions. The findings also reflect adroit technical skills and in-depth planning abilities, more advanced and complex than those of earlier archaeological occurrences in the Levant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goren-Inbar, N -- Feibel, C S -- Verosub, K L -- Melamed, Y -- Kislev, M E -- Tchernov, E -- Saragusti, I -- New York, N.Y. -- Science. 2000 Aug 11;289(5481):944-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Archaeology, Hebrew University, Mt.

    The Xist lncRNA exploits three-dimensional genome architecture to spread across the X chromosome (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-07-06
    Description: Many large noncoding RNAs (lncRNAs) regulate chromatin, but the mechanisms by which they localize to genomic targets remain unexplored. We investigated the localization mechanisms of the Xist lncRNA during X-chromosome inactivation (XCI), a paradigm of lncRNA-mediated chromatin regulation. During the maintenance of XCI, Xist binds broadly across the X chromosome. During initiation of XCI, Xist initially transfers to distal regions across the X chromosome that are not defined by specific sequences. Instead, Xist identifies these regions by exploiting the three-dimensional conformation of the X chromosome. Xist requires its silencing domain to spread across actively transcribed regions and thereby access the entire chromosome. These findings suggest a model in which Xist coats the X chromosome by searching in three dimensions, modifying chromosome structure, and spreading to newly accessible locations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3778663/" 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/PMC3778663/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Engreitz, Jesse M -- Pandya-Jones, Amy -- McDonel, Patrick -- Shishkin, Alexander -- Sirokman, Klara -- Surka, Christine -- Kadri, Sabah -- Xing, Jeffrey -- Goren, Alon -- Lander, Eric S -- Plath, Kathrin -- Guttman, Mitchell -- 1F32GM103139-01/GM/NIGMS NIH HHS/ -- DP5 OD012190/OD/NIH HHS/ -- DP5OD012190/OD/NIH HHS/ -- P01 GM099134/GM/NIGMS NIH HHS/ -- P01GM099134/GM/NIGMS NIH HHS/ -- P50HG006193/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2013 Aug 16;341(6147):1237973. doi: 10.1126/science.1237973.

    Inferences of competence from faces predict election outcomes (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-06-11
    Description: We show that inferences of competence based solely on facial appearance predicted the outcomes of U.S. congressional elections better than chance (e.g., 68.8% of the Senate races in 2004) and also were linearly related to the margin of victory. These inferences were specific to competence and occurred within a 1-second exposure to the faces of the candidates. The findings suggest that rapid, unreflective trait inferences can contribute to voting choices, which are widely assumed to be based primarily on rational and deliberative considerations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Todorov, Alexander -- Mandisodza, Anesu N -- Goren, Amir -- Hall, Crystal C -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1623-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Princeton University, Princeton, NJ 08544, USA. atodorov@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15947187" target="_blank"〉PubMed〈/a〉

    Evidence of hominin control of fire at Gesher Benot Ya'aqov, Israel (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-05-01
    Description: The presence of burned seeds, wood, and flint at the Acheulian site of Gesher Benot Ya'aqov in Israel is suggestive of the control of fire by humans nearly 790,000 years ago. The distribution of the site's small burned flint fragments suggests that burning occurred in specific spots, possibly indicating hearth locations. Wood of six taxa was burned at the site, at least three of which are edible--live, wild barley, and wild grape.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goren-Inbar, Naama -- Alperson, Nira -- Kislev, Mordechai E -- Simchoni, Orit -- Melamed, Yoel -- Ben-Nun, Adi -- Werker, Ella -- New York, N.Y. -- Science. 2004 Apr 30;304(5671):725-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Archaeology, Hebrew University, Mt.

    Spatial organization of hominin activities at Gesher Benot Ya'aqov, Israel (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-19
    Description: The spatial designation of discrete areas for different activities reflects formalized conceptualization of a living space. The results of spatial analyses of a Middle Pleistocene Acheulian archaeological horizon (about 750,000 years ago) at Gesher Benot Ya'aqov, Israel, indicate that hominins differentiated their activities (stone knapping, tool use, floral and faunal processing and consumption) across space. These were organized in two main areas, including multiple activities around a hearth. The diversity of human activities and the distinctive patterning with which they are organized implies advanced organizational skills of the Gesher Benot Ya'aqov hominins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alperson-Afil, Nira -- Sharon, Gonen -- Kislev, Mordechai -- Melamed, Yoel -- Zohar, Irit -- Ashkenazi, Shosh -- Rabinovich, Rivka -- Biton, Rebecca -- Werker, Ella -- Hartman, Gideon -- Feibel, Craig -- Goren-Inbar, Naama -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1677-80. doi: 10.1126/science.1180695.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Archaeology, Hebrew University of Jerusalem, Mount Scopus, Jerusalem 91905, Israel. alperson@mscc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019284" target="_blank"〉PubMed〈/a〉

    Unbiased reconstruction of a mammalian transcriptional network mediating pathogen responses (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-09-05
    Description: Models of mammalian regulatory networks controlling gene expression have been inferred from genomic data but have largely not been validated. We present an unbiased strategy to systematically perturb candidate regulators and monitor cellular transcriptional responses. We applied this approach to derive regulatory networks that control the transcriptional response of mouse primary dendritic cells to pathogens. Our approach revealed the regulatory functions of 125 transcription factors, chromatin modifiers, and RNA binding proteins, which enabled the construction of a network model consisting of 24 core regulators and 76 fine-tuners that help to explain how pathogen-sensing pathways achieve specificity. This study establishes a broadly applicable, comprehensive, and unbiased approach to reveal the wiring and functions of a regulatory network controlling a major transcriptional response in primary mammalian cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2879337/" 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/PMC2879337/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amit, Ido -- Garber, Manuel -- Chevrier, Nicolas -- Leite, Ana Paula -- Donner, Yoni -- Eisenhaure, Thomas -- Guttman, Mitchell -- Grenier, Jennifer K -- Li, Weibo -- Zuk, Or -- Schubert, Lisa A -- Birditt, Brian -- Shay, Tal -- Goren, Alon -- Zhang, Xiaolan -- Smith, Zachary -- Deering, Raquel -- McDonald, Rebecca C -- Cabili, Moran -- Bernstein, Bradley E -- Rinn, John L -- Meissner, Alex -- Root, David E -- Hacohen, Nir -- Regev, Aviv -- DP1 OD003958/OD/NIH HHS/ -- DP1 OD003958-01/OD/NIH HHS/ -- DP2 OD002230/OD/NIH HHS/ -- DP2 OD002230-01/OD/NIH HHS/ -- R21 AI071060/AI/NIAID NIH HHS/ -- R21 AI071060-01/AI/NIAID NIH HHS/ -- R21 AI71060/AI/NIAID NIH HHS/ -- S10 RR026688/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):257-63. doi: 10.1126/science.1179050.

    Dynamic reorganization of river basins (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-08
    Description: River networks evolve as migrating drainage divides reshape river basins and change network topology by capture of river channels. We demonstrate that a characteristic metric of river network geometry gauges the horizontal motion of drainage divides. Assessing this metric throughout a landscape maps the dynamic states of entire river networks, revealing diverse conditions: Drainage divides in the Loess Plateau of China appear stationary; the young topography of Taiwan has migrating divides driving adjustment of major basins; and rivers draining the ancient landscape of the southeastern United States are reorganizing in response to escarpment retreat and coastal advance. The ability to measure the dynamic reorganization of river basins presents opportunities to examine landscape-scale interactions among tectonics, erosion, and ecology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willett, Sean D -- McCoy, Scott W -- Perron, J Taylor -- Goren, Liran -- Chen, Chia-Yu -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1248765. doi: 10.1126/science.1248765.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geological Institute, Swiss Federal Institute of Technology, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604204" target="_blank"〉PubMed〈/a〉

    Inability of oxytocin to activate pyruvate dehydrogenase in the Brattleboro rat (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-28
    Description: Oxytocin has insulin-like activity in that it stimulates lipogenesis and increases pyruvate dehydrogenase activity. However, in adipocytes from homozygous Brattleboro rats oxytocin is incapable of stimulating lipogenesis or pyruvate dehydrogenase activity, although insulin stimulation of both processes is normal and the antilipolytic activity of oxytocin is normal. Thus, the Brattleboro rat provides a new genetic model for the study of oxytocin action, wherein recognition of the chemical mediator is partially defective.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanif, K -- Lederis, K -- Hollenberg, M D -- Goren, H J -- New York, N.Y. -- Science. 1982 May 28;216(4549):1010-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079746" target="_blank"〉PubMed〈/a〉
