  • Observing Supernova 1987A with the Refurbished Hubble Space Telescope
    [作者:France, K; McCray, R; Heng, K; Kirshner, RP; Challis, P; Bouchet, P; Crotts, A; Dwek, E; Fransson, C; Garnavich, PM; Larsson, J; Lawrence, SS; Lundqvist, P; Panagia, N; Pun, CSJ; Smith, N; Sollerman, J; Sonneborn, G; Stocke, JT; Wang, LF; Wheeler, JC,期刊:Science, 页码:1624-1627 , 文章类型: Article,,卷期:2010年329-5999]
  • Observations with the Hubble Space Telescope (HST), conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A. Comparing observations taken in 2010 wi...
  • Optical Clocks and Relativity
    [作者:Chou, CW; Hume, DB; Rosenband, T; Wineland, DJ,期刊:Science, 页码:1630-1633 , 文章类型: Article,,卷期:2010年329-5999]
  • Observers in relative motion or at different gravitational potentials measure disparate clock rates. These predictions of relativity have previously been observed with atomic clocks at high velocities and with large chan...
  • Alkali-Stabilized Pt-OHx Species Catalyze Low-Temperature Water-Gas Shift Reactions
    [作者:Zhai, YP; Pierre, D; Si, R; Deng, WL; Ferrin, P; Nilekar, AU; Peng, GW; Herron, JA; Bell, DC; Saltsburg, H; Mavrikakis, M; Flytzani-Stephanopoulos, M,期刊:Science, 页码:1633-1636 , 文章类型: Article,,卷期:2010年329-5999]
  • We report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H2O + CO -> H-2 + CO2) used for producing H2...
  • Genetic Restoration of the Florida Panther
    [作者:Johnson, WE; Onorato, DP; Roelke, ME; Land, ED; Cunningham, M; Belden, RC; McBride, R; Jansen, D; Lotz, M; Shindle, D; Howard, J; Wildt, DE; Penfold, LM; Hostetler, JA; Oli, MK; O'Brien, SJ,期刊:Science, 页码:1641-1645 , 文章类型: Article,,卷期:2010年329-5999]
  • The rediscovery of remnant Florida panthers (Puma concolor coryi) in southern Florida swamplands prompted a program to protect and stabilize the population. In 1995, conservation managers translocated eight female pumas ...
  • A Unifying Genetic Model for Facioscapulohumeral Muscular Dystrophy
    [作者:Lemmers, RJLF; van der Vliet, PJ; Klooster, R; Sacconi, S; Camano, P; Dauwerse, JG; Snider, L; Straasheijm, KR; van Ommen, GJ; Padberg, GW; Miller, DG; Tapscott, SJ; Tawil, R; Frants, RR; van der Maarel, SM,期刊:Science, 页码:1650-1653 , 文章类型: Article,,卷期:2010年329-5999]
  • Facioscapulohumeral muscular dystrophy (FSHD) is a common form of muscular dystrophy in adults that is foremost characterized by progressive wasting of muscles in the upper body. FSHD is associated with contraction of D4...
  • A General Mechanism for Network-Dosage Compensation in Gene Circuits
    [作者:Acar, M; Pando, BF; Arnold, FH; Elowitz, MB; van Oudenaarden, A,期刊:Science, 页码:1656-1660 , 文章类型: Article,,卷期:2010年329-5999]
  • Coping with variations in network dosage is crucial for maintaining optimal function in gene networks. We explored how network structure facilitates network-level dosage compensation. By using the yeast galactose network...
