We show that wMelPop induces up-regulation of the mosquito's ... Identification of Carboniferous (320 Million Years Old) Class Ic Amber [作者：Bray, PS; Anderson, KB,期刊：Science, 页码：132-134 , 文章类型： Article，,卷期：2009年326-5949] The presence of amber, the fossil form of the resins produced by many types of higher plants, has been reported from many localities in Mesozoic and Cenozoic rocks. We have found Class I (polylabdanoid) amber in Carbonif... Preferential Growth of Single-Walled Carbon Nanotubes with Metallic Conductivity [作者：Harutyunyan, AR; Chen, GG; Paronyan, TM; Pigos, EM; Kuznetsov, OA; Hewaparakrama, K; Kim, SM; Zakharov, D; Stach, EA; Sumanasekera, GU,期刊：Science, 页码：116-120 , 文章类型： Article，,卷期：2009年326-5949] Single-walled carbon nanotubes can be classified as either metallic or semiconducting, depending on their conductivity, which is determined by their chirality. Existing synthesis methods cannot controllably grow nanotube... Rapid Resurgence of Marine Productivity After the Cretaceous-Paleogene Mass Extinction [作者：Sepulveda, J; Wendler, JE; Summons, RE; Hinrichs, KU,期刊：Science, 页码：129-132 , 文章类型： Article，,卷期：2009年326-5949] The course of the biotic recovery after the impact-related disruption of photosynthesis and mass extinction event at the Cretaceous-Paleogene boundary has been intensely debated. The resurgence of marine primary producti... Enhanced Sulfur and Coking Tolerance of a Mixed Ion Conductor for SOFCs: BaZr0.1Ce0.7Y0.2-xYbxO3-delta [作者：Yang, L; Wang, SZ; Blinn, K; Liu, MF; Liu, Z; Cheng, Z; Liu, ML,期刊：Science, 页码：126-129 , 文章类型： Article，,卷期：2009年326-5949] The anode materials that have been developed for solid oxide fuel cells (SOFCs) are vulnerable to deactivation by carbon buildup (coking) from hydrocarbon fuels or by sulfur contamination (poisoning). We report on a mixe... Chiral Organic Ion Pair Catalysts Assembled Through a Hydrogen-Bonding Network [作者：Uraguchi, D; Ueki, Y; Ooi, T,期刊：Science, 页码：120-123 , 文章类型： Article，,卷期：2009年326-5949] Research to develop structurally discrete, chiral supramolecular catalysts for asymmetric organic transformations has met with limited success. Here, we report that a chiral tetraaminophosphonium cation, two phenols, and... Nitrous Oxide (N2O): The Dominant Ozone-Depleting Substance Emitted in the 21st Century [作者：Ravishankara, AR; Daniel, JS; Portmann, RW,期刊：Science, 页码：123-125 , 文章类型： Article，,卷期：2009年326-5949] By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission... Genome-Wide RNAi Screen Identifies Letm1 as a Mitochondrial Ca2+/H+ Antiporter [作者：Jiang, DW; Zhao, LL; Clapham, DE,期刊：Science, 页码：144-147 , 文章类型： Article，,卷期：2009年326-5949] Mitochondria are integral components of cellular calcium (Ca2+) signaling. Calcium stimulates mitochondrial adenosine 5'-triphosphate production, but can also initiate apoptosis. In turn, cytoplasmic Ca2+ concentrations ... Global Surface Wave Tomography Using Seismic Hum [作者：Nishida, K; Montagner, JP; Kawakatsu, H,期刊：Science, 页码：112-112 , 文章类型： Article，,卷期：2009年326-5949] Coat Variation in the Domestic Dog Is Governed by Variants in Three Genes [作者：Cadieu, E; Neff, MW; Quignon, P; Walsh, K; Chase, K; Parker, HG; VonHoldt, BM; Rhue, A; Boyko, A; Byers, A; Wong, A; Mosher, DS; Elkahloun, AG; Spady, TC; Andre, C; Lark, KG; Cargill, M; Bustamante, CD; Wayne, RK; Ostrander, EA,期刊：Science, 页码：150-153 , 文章类型： Article，,卷期：2009年326-5949] Coat color and type are essential characteristics of domestic dog breeds. Although the genetic basis of coat color has been well characterized, relatively little is known about the genes influencing coat growth pattern, ... Fluxonium: Single Cooper-Pair Circuit Free of Charge Offsets [作者：Manucharyan, VE; Koch, J; Glazman, LI; Devoret, MH,期刊：Science, 页码：113-116 , 文章类型： Article，,卷期：2009年326-5949] The promise of single Cooper-pair quantum circuits based on tunnel junctions for metrology and quantum information applications is severely limited by the influence of offset charges: random, slowly drifting microscopic ...
