- Light Propagation with Phase Discontinuities: Generalized Laws of Reflection and Refraction
[作者:Yu, NF; Genevet, P; Kats, MA; Aieta, F; Tetienne, JP; Capasso, F; Gaburro, Z,期刊:Science, 页码:333-337 , 文章类型: Article,,卷期:2011年334-6054]
- Conventional optical components rely on gradual phase shifts accumulated during light propagation to shape light beams. New degrees of freedom are attained by introducing abrupt phase changes over the scale of the wavele...
- Detection of the Water Reservoir in a Forming Planetary System
[作者:Hogerheijde, MR; Bergin, EA; Brinch, C; Cleeves, LI; Fogel, JKJ; Blake, GA; Dominik, C; Lis, DC; Melnick, G; Neufeld, D; Panic, O; Pearson, JC; Kristensen, L; Yildiz, UA; van Dishoeck, EF,期刊:Science, 页码:338-340 , 文章类型: Article,,卷期:2011年334-6054]
- Icy bodies may have delivered the oceans to the early Earth, yet little is known about water in the ice-dominated regions of extrasolar planet-forming disks. The Heterodyne Instrument for the Far-Infrared on board the He...
- Supramolecular Linear Heterojunction Composed of Graphite-Like Semiconducting Nanotubular Segments
[作者:Zhang, W; Jin, WS; Fukushima, T; Saeki, A; Seki, S; Aida, T,期刊:Science, 页码:340-343 , 文章类型: Article,,卷期:2011年334-6054]
- One-dimensionally connected organic nanostructures with dissimilar semiconducting properties are expected to provide a reliable platform in understanding the behaviors of photocarriers, which are important for the develo...
- 800,000 Years of Abrupt Climate Variability
[作者:Barker, S; Knorr, G; Edwards, RL; Parrenin, F; Putnam, AE; Skinner, LC; Wolff, E; Ziegler, M,期刊:Science, 页码:347-351 , 文章类型: Article,,卷期:2011年334-6054]
- We constructed an 800,000-year synthetic record of Greenland climate variability based on the thermal bipolar seesaw model. Our Greenland analog reproduces much of the variability seen in the Greenland ice cores over the...
- Pre-Clovis Mastodon Hunting 13,800 Years Ago at the Manis Site, Washington
[作者:Waters, MR; Stafford, TW; McDonald, HG; Gustafson, C; Rasmussen, M; Cappellini, E; Olsen, JV; Szklarczyk, D; Jensen, LJ; Gilbert, MTP; Willerslev, E,期刊:Science, 页码:351-353 , 文章类型: Article,,卷期:2011年334-6054]
- The tip of a projectile point made of mastodon bone is embedded in a rib of a single disarticulated mastodon at the Manis site in the state of Washington. Radiocarbon dating and DNA analysis show that the rib is associat...
- ER Tubules Mark Sites of Mitochondrial Division
[作者:Friedman, JR; Lackner, LL; West, M; DiBenedetto, JR; Nunnari, J; Voeltz, GK,期刊:Science, 页码:358-362 , 文章类型: Article,,卷期:2011年334-6054]
- Mitochondrial structure and distribution are regulated by division and fusion events. Mitochondrial division is regulated by Dnm1/Drp1, a dynamin-related protein that forms helices around mitochondria to mediate fission....
- Antimicrobial Peptides Keep Insect Endosymbionts Under Control
[作者:Login, FH; Balmand, S; Vallier, A; Vincent-Monegat, C; Vigneron, A; Weiss-Gayet, M; Rochat, D; Heddi, A,期刊:Science, 页码:362-365 , 文章类型: Article,,卷期:2011年334-6054]
- Vertically transmitted endosymbionts persist for millions of years in invertebrates and play an important role in animal evolution. However, the functional basis underlying the maintenance of these long-term resident bac...
- Stochastic Pulse Regulation in Bacterial Stress Response
[作者:Locke, JCW; Young, JW; Fontes, M; Jimenez, MJH; Elowitz, MB,期刊:Science, 页码:366-369 , 文章类型: Article,,卷期:2011年334-6054]
- Gene regulatory circuits can use dynamic, and even stochastic, strategies to respond to environmental conditions. We examined activation of the general stress response mediated by the alternative sigma factor, sigma(B), ...
