- We showed that alumina (Al2O3) overcoating of supported metal nanoparticles (NPs) effectively reduced deactivation by coking and sintering in high-temperature applications of heterogeneous catalysts. We overcoated pallad...
- Natural SIV Hosts: Showing AIDS the Door
[作者：Chahroudi, A; Bosinger, SE; Vanderford, TH; Paiardini, M; Silvestri, G,期刊：Science, 页码：1188-1193 , 文章类型： Review，,卷期：2012年335-6073]
- Many species of African nonhuman primates are naturally infected with simian immunodeficiency viruses (SIVs) in the wild and in captivity. In contrast to HIV-infected humans, these natural SIV hosts typically do not deve...
- Nuclear Fuel in a Reactor Accident
[作者：Burns, PC; Ewing, RC; Navrotsky, A,期刊：Science, 页码：1184-1188 , 文章类型： Review，,卷期：2012年335-6073]
- Nuclear accidents that lead to melting of a reactor core create heterogeneous materials containing hundreds of radionuclides, many with short half-lives. The long-lived fission products and transuranium elements within d...
- Nucleosomes Suppress Spontaneous Mutations Base-Specifically in Eukaryotes
[作者：Chen, XS; Chen, ZD; Chen, H; Su, ZJ; Yang, JF; Lin, FQ; Shi, SH; He, XL,期刊：Science, 页码：1235-1238 , 文章类型： Article，,卷期：2012年335-6073]
- It is unknown how the composition and structure of DNA within the cell affect spontaneous mutations. Theory suggests that in eukaryotic genomes, nucleosomal DNA undergoes fewer C -> T mutations because of suppressed cyto...
- Designing Responsive Buckled Surfaces by Halftone Gel Lithography
[作者：Kim, J; Hanna, JA; Byun, M; Santangelo, CD; Hayward, RC,期刊：Science, 页码：1201-1205 , 文章类型： Article，,卷期：2012年335-6073]
- Self-actuating materials capable of transforming between three-dimensional shapes have applications in areas as diverse as biomedicine, robotics, and tunable micro-optics. We introduce a method of photopatterning polymer...
- A Bruce Effect in Wild Geladas
[作者：Roberts, EK; Lu, A; Bergman, TJ; Beehner, JC,期刊：Science, 页码：1222-1225 , 文章类型： Article，,卷期：2012年335-6073]
- Female rodents are known to terminate pregnancies after exposure to unfamiliar males ("Bruce effect"). Although laboratory support abounds, direct evidence for a Bruce effect under natural conditions is lacking. Here, we...
- Triggering a Cell Shape Change by Exploiting Preexisting Actomyosin Contractions
[作者：Roh-Johnson, M; Shemer, G; Higgins, CD; McClellan, JH; Werts, AD; Tulu, US; Gao, L; Betzig, E; Kiehart, DP; Goldstein, B,期刊：Science, 页码：1232-1235 , 文章类型： Article，,卷期：2012年335-6073]
- Apical constriction changes cell shapes, driving critical morphogenetic events, including gastrulation in diverse organisms and neural tube closure in vertebrates. Apical constriction is thought to be triggered by contra...
- Intensifying Weathering and Land Use in Iron Age Central Africa
[作者：Bayon, G; Dennielou, B; Etoubleau, J; Ponzevera, E; Toucanne, S; Bermell, S,期刊：Science, 页码：1219-1222 , 文章类型： Article，,卷期：2012年335-6073]
- About 3000 years ago, a major vegetation change occurred in Central Africa, when rainforest trees were abruptly replaced by savannas. Up to this point, the consensus of the scientific community has been that the forest d...
- Reconstruction of Microraptor and the Evolution of Iridescent Plumage
[作者：Li, QG; Gao, KQ; Meng, QJ; Clarke, JA; Shawkey, MD; D'Alba, L; Pei, R; Ellison, M; Norell, MA; Vinther, J,期刊：Science, 页码：1215-1219 , 文章类型： Article，,卷期：2012年335-6073]
- Iridescent feather colors involved in displays of many extant birds are produced by nanoscale arrays of melanin-containing organelles (melanosomes). Data relevant to the evolution of these colors and the properties of me...
