- Ion-Mediated Electron Transfer in a Supramolecular Donor-Acceptor Ensemble
[作者:Park, JS; Karnas, E; Ohkubo, K; Chen, P; Kadish, KM; Fukuzumi, S; Bielawski, CW; Hudnall, TW; Lynch, VM; Sessler, JL,期刊:Science, 页码:1324-1327 , 文章类型: Article,,卷期:2010年329-5997]
- Ion binding often mediates electron transfer in biological systems as a cofactor strategy, either as a promoter or as an inhibitor. However, it has rarely, if ever, been exploited for that purpose in synthetic host-guest...
- Future CO2 Emissions and Climate Change from Existing Energy Infrastructure
[作者:Davis, SJ; Caldeira, K; Matthews, HD,期刊:Science, 页码:1330-1333 , 文章类型: Article,,卷期:2010年329-5997]
- Slowing climate change requires overcoming inertia in political, technological, and geophysical systems. Of these, only geophysical warming commitment has been quantified. We estimated the commitment to future emissions ...
- Stable Isotope Measurements of Martian Atmospheric CO2 at the Phoenix Landing Site
[作者:Niles, PB; Boynton, WV; Hoffman, JH; Ming, DW; Hamara, D,期刊:Science, 页码:1334-1337 , 文章类型: Article,,卷期:2010年329-5997]
- Carbon dioxide is a primary component of the martian atmosphere and reacts readily with water and silicate rocks. Thus, the stable isotopic composition of CO2 can reveal much about the history of volatiles on the planet....
- Planar Cell Polarity Acts Through Septins to Control Collective Cell Movement and Ciliogenesis
[作者:Kim, SK; Shindo, A; Park, TJ; Oh, EC; Ghosh, S; Gray, RS; Lewis, RA; Johnson, CA; Attie-Bittach, T; Katsanis, N; Wallingford, JB,期刊:Science, 页码:1337-1340 , 文章类型: Article,,卷期:2010年329-5997]
- The planar cell polarity (PCP) signaling pathway governs collective cell movements during vertebrate embryogenesis, and certain PCP proteins are also implicated in the assembly of cilia. The septins are cytoskeletal prot...
- Self-Assembly of Filopodia-Like Structures on Supported Lipid Bilayers
[作者:Lee, K; Gallop, JL; Rambani, K; Kirschner, MW,期刊:Science, 页码:1341-1345 , 文章类型: Article,,卷期:2010年329-5997]
- Filopodia are finger-like protrusive structures, containing actin bundles. By incubating frog egg extracts with supported lipid bilayers containing phosphatidylinositol 4,5 bisphosphate, we have reconstituted the assembl...
- Aryl Hydrocarbon Receptor Antagonists Promote the Expansion of Human Hematopoietic Stem Cells
[作者:Boitano, AE; Wang, JA; Romeo, R; Bouchez, LC; Parker, AE; Sutton, SE; Walker, JR; Flaveny, CA; Perdew, GH; Denison, MS; Schultz, PG; Cooke, MP,期刊:Science, 页码:1345-1348 , 文章类型: Article,,卷期:2010年329-5997]
- Although practiced clinically for more than 40 years, the use of hematopoietic stem cell (HSC) transplants remains limited by the ability to expand these cells ex vivo. An unbiased screen with primary human HSCs identifi...
- Human SIRT6 Promotes DNA End Resection Through CtIP Deacetylation
[作者:Kaidi, A; Weinert, BT; Choudhary, C; Jackson, SP,期刊:Science, 页码:1348-1353 , 文章类型: Article,,卷期:2010年329-5997]
- SIRT6 belongs to the sirtuin family of protein lysine deacetylases, which regulate aging and genome stability. We found that human SIRT6 has a role in promoting DNA end resection, a crucial step in DNA double-strand brea...
- Prediction of Individual Brain Maturity Using fMRI
[作者:Dosenbach, NUF; Nardos, B; Cohen, AL; Fair, DA; Power, JD; Church, JA; Nelson, SM; Wig, GS; Vogel, AC; Lessov-Schlaggar, CN; Barnes, KA; Dubis, JW; Feczko, E; Coalson, RS; Pruett, JR; Barch, DM; Petersen, SE; Schlaggar, BL,期刊:Science, 页码:1358-1361 , 文章类型: Article,,卷期:2010年329-5997]
- 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 p...
