- A Giant Planet Around a Metal-Poor Star of Extragalactic Origin
[作者:Setiawan, J; Klement, RJ; Henning, T; Rix, HW; Rochau, B; Rodmann, J; Schulze-Hartung, T,期刊:Science, 页码:1642-1644 , 文章类型: Article,,卷期:2010年330-6011]
- Stars in their late stage of evolution, such as horizontal branch stars, are still largely unexplored for planets. We detected a planetary companion around HIP 13044, a very metal-poor star on the red horizontal branch, ...
- Experimental Spin Ratchet
[作者:Costache, MV; Valenzuela, SO,期刊:Science, 页码:1645-1648 , 文章类型: Article,,卷期:2010年330-6011]
- Spintronics relies on the ability to transport and use the spin properties of an electron rather than its charge. We describe a spin ratchet at the single-electron level that produces spin currents with no net bias or ch...
- Spin Transfer Torques in MnSi at Ultralow Current Densities
[作者:Jonietz, F; Muhlbauer, S; Pfleiderer, C; Neubauer, A; Munzer, W; Bauer, A; Adams, T; Georgii, R; Boni, P; Duine, RA; Everschor, K; Garst, M; Rosch, A,期刊:Science, 页码:1648-1651 , 文章类型: Article,,卷期:2010年330-6011]
- Spin manipulation using electric currents is one of the most promising directions in the field of spintronics. We used neutron scattering to observe the influence of an electric current on the magnetic structure in a bul...
- Electronic Spin Storage in an Electrically Readable Nuclear Spin Memory with a Lifetime > 100 Seconds
[作者:McCamey, DR; Van Tol, J; Morley, GW; Boehme, C,期刊:Science, 页码:1652-1656 , 文章类型: Article,,卷期:2010年330-6011]
- Electron spins are strong candidates with which to implement spintronics because they are both mobile and able to be manipulated. The relatively short lifetimes of electron spins, however, present a problem for the long-...
- Entropically Stabilized Local Dipole Formation in Lead Chalcogenides
[作者:Bozin, ES; Malliakas, CD; Souvatzis, P; Proffen, T; Spaldin, NA; Kanatzidis, MG; Billinge, SJL,期刊:Science, 页码:1660-1663 , 文章类型: Article,,卷期:2010年330-6011]
- We report the observation of local structural dipoles that emerge from an undistorted ground state on warming, in contrast to conventional structural phase transitions in which distortions emerge on cooling. Using experi...
- Structural Basis of Biological N2O Generation by Bacterial Nitric Oxide Reductase
[作者:Hino, T; Matsumoto, Y; Nagano, S; Sugimoto, H; Fukumori, Y; Murata, T; Iwata, S; Shiro, Y,期刊:Science, 页码:1666-1670 , 文章类型: Article,,卷期:2010年330-6011]
- Nitric oxide reductase (NOR) is an iron-containing enzyme that catalyzes the reduction of nitric oxide (NO) to generate a major greenhouse gas, nitrous oxide (N2O). Here, we report the crystal structure of NOR from Pseud...
- The Substrate of Greatwall Kinase, Arpp19, Controls Mitosis by Inhibiting Protein Phosphatase 2A
[作者:Gharbi-Ayachi, A; Labbe, JC; Burgess, A; Vigneron, S; Strub, JM; Brioudes, E; Van-Dorsselaer, A; Castro, A; Lorca, T,期刊:Science, 页码:1673-1677 , 文章类型: Article,,卷期:2010年330-6011]
- Initiation and maintenance of mitosis require the activation of protein kinase cyclin B-Cdc2 and the inhibition of protein phosphatase 2A (PP2A), which, respectively, phosphorylate and dephosphorylate mitotic substrates....
- Cholinergic Interneurons Control Local Circuit Activity and Cocaine Conditioning
[作者:Witten, IB; Lin, SC; Brodsky, M; Prakash, R; Diester, I; Anikeeva, P; Gradinaru, V; Ramakrishnan, C; Deisseroth, K,期刊:Science, 页码:1677-1681 , 文章类型: Article,,卷期:2010年330-6011]
- Cholinergic neurons are widespread, and pharmacological modulation of acetylcholine receptors affects numerous brain processes, but such modulation entails side effects due to limitations in specificity for receptor type...
