    Efficient generation of H2 by splitting water with an isothermal redox cycle (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-03
    Description: Solar thermal water-splitting (STWS) cycles have long been recognized as a desirable means of generating hydrogen gas (H2) from water and sunlight. Two-step, metal oxide-based STWS cycles generate H2 by sequential high-temperature reduction and water reoxidation of a metal oxide. The temperature swings between reduction and oxidation steps long thought necessary for STWS have stifled STWS's overall efficiency because of thermal and time losses that occur during the frequent heating and cooling of the metal oxide. We show that these temperature swings are unnecessary and that isothermal water splitting (ITWS) at 1350 degrees C using the "hercynite cycle" exhibits H2 production capacity 〉3 and 〉12 times that of hercynite and ceria, respectively, per mass of active material when reduced at 1350 degrees C and reoxidized at 1000 degrees C.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muhich, Christopher L -- Evanko, Brian W -- Weston, Kayla C -- Lichty, Paul -- Liang, Xinhua -- Martinek, Janna -- Musgrave, Charles B -- Weimer, Alan W -- New York, N.Y. -- Science. 2013 Aug 2;341(6145):540-2. doi: 10.1126/science.1239454.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical and Biological Engineering, University of Colorado, Boulder, CO 80303, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23908235" target="_blank"〉PubMed〈/a〉

    Genetic and molecular basis of drug resistance and species-specific drug action in schistosome parasites (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-11-23
    Description: Oxamniquine resistance evolved in the human blood fluke (Schistosoma mansoni) in Brazil in the 1970s. We crossed parental parasites differing ~500-fold in drug response, determined drug sensitivity and marker segregation in clonally derived second-generation progeny, and identified a single quantitative trait locus (logarithm of odds = 31) on chromosome 6. A sulfotransferase was identified as the causative gene by using RNA interference knockdown and biochemical complementation assays, and we subsequently demonstrated independent origins of loss-of-function mutations in field-derived and laboratory-selected resistant parasites. These results demonstrate the utility of linkage mapping in a human helminth parasite, while crystallographic analyses of protein-drug interactions illuminate the mode of drug action and provide a framework for rational design of oxamniquine derivatives that kill both S. mansoni and S. haematobium, the two species responsible for 〉99% of schistosomiasis cases worldwide.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136436/" 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/PMC4136436/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valentim, Claudia L L -- Cioli, Donato -- Chevalier, Frederic D -- Cao, Xiaohang -- Taylor, Alexander B -- Holloway, Stephen P -- Pica-Mattoccia, Livia -- Guidi, Alessandra -- Basso, Annalisa -- Tsai, Isheng J -- Berriman, Matthew -- Carvalho-Queiroz, Claudia -- Almeida, Marcio -- Aguilar, Hector -- Frantz, Doug E -- Hart, P John -- LoVerde, Philip T -- Anderson, Timothy J C -- 098051/Wellcome Trust/United Kingdom -- 5R21-AI072704/AI/NIAID NIH HHS/ -- 5R21-AI096277/AI/NIAID NIH HHS/ -- C06 RR013556/RR/NCRR NIH HHS/ -- HHSN272201000005I/PHS HHS/ -- R01 AI097576/AI/NIAID NIH HHS/ -- R01-AI097576/AI/NIAID NIH HHS/ -- R21 AI072704/AI/NIAID NIH HHS/ -- R21 AI096277/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1385-9. doi: 10.1126/science.1243106.

    Stepwise evolution of essential centromere function in a Drosophila neogene (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-06-08
    Description: Evolutionarily young genes that serve essential functions represent a paradox; they must perform a function that either was not required until after their birth or was redundant with another gene. How young genes rapidly acquire essential function is largely unknown. We traced the evolutionary steps by which the Drosophila gene Umbrea acquired an essential role in chromosome segregation in D. melanogaster since the gene's origin less than 15 million years ago. Umbrea neofunctionalization occurred via loss of an ancestral heterochromatin-localizing domain, followed by alterations that rewired its protein interaction network and led to species-specific centromere localization. Our evolutionary cell biology approach provides temporal and mechanistic detail about how young genes gain essential function. Such innovations may constantly alter the repertoire of centromeric proteins in eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4119826/" 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/PMC4119826/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ross, Benjamin D -- Rosin, Leah -- Thomae, Andreas W -- Hiatt, Mary Alice -- Vermaak, Danielle -- de la Cruz, Aida Flor A -- Imhof, Axel -- Mellone, Barbara G -- Malik, Harmit S -- R01 GM074108/GM/NIGMS NIH HHS/ -- R01GM074108/GM/NIGMS NIH HHS/ -- T32HG000035/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Jun 7;340(6137):1211-4. doi: 10.1126/science.1234393.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cellular Biology Program, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23744945" target="_blank"〉PubMed〈/a〉

    Unraveling the mechanism of protein disaggregation through a ClpB-DnaK interaction (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-09
    Description: HSP-100 protein machines, such as ClpB, play an essential role in reactivating protein aggregates that can otherwise be lethal to cells. Although the players involved are known, including the DnaK/DnaJ/GrpE chaperone system in bacteria, details of the molecular interactions are not well understood. Using methyl-transverse relaxation-optimized nuclear magnetic resonance spectroscopy, we present an atomic-resolution model for the ClpB-DnaK complex, which we verified by mutagenesis and functional assays. ClpB and GrpE compete for binding to the DnaK nucleotide binding domain, with GrpE binding inhibiting disaggregation. DnaK, in turn, plays a dual role in both disaggregation and subsequent refolding of polypeptide chains as they emerge from the aggregate. On the basis of a combined structural-biochemical analysis, we propose a model for the mechanism of protein aggregate reactivation by ClpB.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenzweig, Rina -- Moradi, Shoeib -- Zarrine-Afsar, Arash -- Glover, John R -- Kay, Lewis E -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2013 Mar 1;339(6123):1080-3. doi: 10.1126/science.1233066.

    Little emperors: behavioral impacts of China's One-Child Policy (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-01-12
    Description: 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.

    Pivotal roles of cGAS-cGAMP signaling in antiviral defense and immune adjuvant effects (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-31
    Description: Invasion of microbial DNA into the cytoplasm of animal cells triggers a cascade of host immune reactions that help clear the infection; however, self DNA in the cytoplasm can cause autoimmune diseases. Biochemical approaches led to the identification of cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) as a cytosolic DNA sensor that triggers innate immune responses. Here, we show that cells from cGAS-deficient (cGas(-/-)) mice, including fibroblasts, macrophages, and dendritic cells, failed to produce type I interferons and other cytokines in response to DNA transfection or DNA virus infection. cGas(-/-) mice were more susceptible to lethal infection with herpes simplex virus 1 (HSV1) than wild-type mice. We also show that cGAMP is an adjuvant that boosts antigen-specific T cell activation and antibody production in mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3863637/" 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/PMC3863637/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Xiao-Dong -- Wu, Jiaxi -- Gao, Daxing -- Wang, Hua -- Sun, Lijun -- Chen, Zhijian J -- 5T32AI070116/AI/NIAID NIH HHS/ -- AI-093967/AI/NIAID NIH HHS/ -- R01 AI093967/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1390-4. doi: 10.1126/science.1244040.

    Spatial dynamics of chromosome translocations in living cells (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-10
    Description: Chromosome translocations are a hallmark of cancer cells. We have developed an experimental system to visualize the formation of translocations in living cells and apply it to characterize the spatial and dynamic properties of translocation formation. We demonstrate that translocations form within hours of the occurrence of double-strand breaks (DSBs) and that their formation is cell cycle-independent. Translocations form preferentially between prepositioned genome elements, and perturbation of key factors of the DNA repair machinery uncouples DSB pairing from translocation formation. These observations generate a spatiotemporal framework for the formation of translocations in living cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roukos, Vassilis -- Voss, Ty C -- Schmidt, Christine K -- Lee, Seungtaek -- Wangsa, Darawalee -- Misteli, Tom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):660-4. doi: 10.1126/science.1237150.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Cancer Institute, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23929981" target="_blank"〉PubMed〈/a〉
