    Robotic observations of enhanced carbon biomass and export at 55 degrees during SOFeX (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-17
    Description: Autonomous floats profiling in high-nitrate low-silicate waters of the Southern Ocean observed carbon biomass variability and carbon exported to depths of 100 m during the 2002 Southern Ocean Iron Experiment (SOFeX) to detect the effects of iron fertilization of surface water there. Control and "in-patch" measurements documented a greater than fourfold enhancement of carbon biomass in the iron-amended waters. Carbon export through 100 m increased two- to sixfold as the patch subducted below a front. The molar ratio of iron added to carbon exported ranged between 10(4) and 10(5). The biomass buildup and export were much higher than expected for iron-amended low-silicate waters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bishop, James K B -- Wood, Todd J -- Davis, Russ E -- Sherman, Jeffrey T -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):417-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Earth Sciences Division, Lawrence Berkeley National Laboratory, 1 Cyclotron Road, MS 90-1116, Berkeley, CA 94720, USA.

    Cis-acting regulatory variation in the human genome (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-23
    Description: The systematic screening of the human genome for genetic variants that affect gene regulation should advance our fundamental understanding of phenotypic diversity and lead to the identification of alleles that modify disease risk. There are several challenges in localizing regulatory polymorphisms, including the wide spectrum of cis-acting regulatory mechanisms, the inconsistent effects of regulatory variants in different tissues, and the difficulty in isolating the causal variants that are in linkage disequilibrium with many other variants. We discuss the current state of knowledge and technologies used for mapping and characterizing genetic variation controlling human gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pastinen, Tomi -- Hudson, Thomas J -- New York, N.Y. -- Science. 2004 Oct 22;306(5696):647-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McGill University and Genome Quebec Innovation Centre, 740 Drive Penfield Avenue, Montreal, Quebec H3A 1A4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15499010" target="_blank"〉PubMed〈/a〉

    The Gs-linked receptor GPR3 maintains meiotic arrest in mammalian oocytes (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-14
    Description: Mammalian oocytes are held in prophase arrest by an unknown signal from the surrounding somatic cells. Here we show that the orphan Gs-linked receptor GPR3, which is localized in the oocyte, maintains this arrest. Oocytes from Gpr3 knockout mice resume meiosis within antral follicles, independently of an increase in luteinizing hormone, and this phenotype can be reversed by injection of Gpr3 RNA into the oocytes. Thus, the GPR3 receptor is a link in communication between the somatic cells and oocyte of the ovarian follicle and is crucial for the regulation of meiosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehlmann, Lisa M -- Saeki, Yoshinaga -- Tanaka, Shigeru -- Brennan, Thomas J -- Evsikov, Alexei V -- Pendola, Frank L -- Knowles, Barbara B -- Eppig, John J -- Jaffe, Laurinda A -- New York, N.Y. -- Science. 2004 Dec 10;306(5703):1947-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Connecticut Health Center (UCHC), Farmington, CT 06032, USA. lmehlmann@neuron.uchc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15591206" target="_blank"〉PubMed〈/a〉

    Curving and frustrating flatland (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-02
    Description: Two polymer chains that occupy equal volumes when covalently linked together at one end self-assemble into an alternating lamellar morphology that has a characteristic period dictated by the molecular weight. When such copolymers are confined within alumina membranes that have cylindrical pores with diameters comparable to the repeat period, the interaction of the blocks with the confining walls and the imposed curvature induces a morphological transformation to relieve the constraints. Here, we show a lamella-to-toroid transition, captured through the dissolution of the surrounding membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shin, Kyusoon -- Xiang, Hongqi -- Moon, Sung In -- Kim, Taehyung -- McCarthy, Thomas J -- Russell, Thomas P -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):76.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Polymer Science and Engineering, Silvio O.

    InSAR observations of low slip rates on the major faults of western Tibet (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-07-13
    Description: Two contrasting views of the active deformation of Asia dominate the debate about how continents deform: (i) The deformation is primarily localized on major faults separating crustal blocks or (ii) deformation is distributed throughout the continental lithosphere. In the first model, western Tibet is being extruded eastward between the major faults bounding the region. Surface displacement measurements across the western Tibetan plateau using satellite radar interferometry (InSAR) indicate that slip rates on the Karakoram and Altyn Tagh faults are lower than would be expected for the extrusion model and suggest a significant amount of internal deformation in Tibet.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, Tim J -- Parsons, Barry -- England, Philip C -- Fielding, Eric J -- New York, N.Y. -- Science. 2004 Jul 9;305(5681):236-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉COMET, Department of Earth Sciences, University of Oxford, Oxford, UK. tim.wright@earth.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15247476" target="_blank"〉PubMed〈/a〉

    Terahertz magnetic response from artificial materials (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-03-06
    Description: We show that magnetic response at terahertz frequencies can be achieved in a planar structure composed of nonmagnetic conductive resonant elements. The effect is realized over a large bandwidth and can be tuned throughout the terahertz frequency regime by scaling the dimensions of the structure. We suggest that artificial magnetic structures, or hybrid structures that combine natural and artificial magnetic materials, can play a key role in terahertz devices.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yen, T J -- Padilla, W J -- Fang, N -- Vier, D C -- Smith, D R -- Pendry, J B -- Basov, D N -- Zhang, X -- New York, N.Y. -- Science. 2004 Mar 5;303(5663):1494-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Mechanical and Aerospace Engineering, University of California at Los Angeles, 420 Westwood Plaza, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15001772" target="_blank"〉PubMed〈/a〉

    Evidence that nitric acid increases relative humidity in low-temperature cirrus clouds (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-24
    Description: In situ measurements of the relative humidity with respect to ice (RHi) and of nitric acid (HNO3) were made in both natural and contrail cirrus clouds in the upper troposphere. At temperatures lower than 202 kelvin, RHi values show a sharp increase to average values of over 130% in both cloud types. These enhanced RHi values are attributed to the presence of a new class of HNO3-containing ice particles (Delta-ice). We propose that surface HNO3 molecules prevent the ice/vapor system from reaching equilibrium by a mechanism similar to that of freezing point depression by antifreeze proteins. Delta-ice represents a new link between global climate and natural and anthropogenic nitrogen oxide emissions. Including Delta-ice in climate models will alter simulated cirrus properties and the distribution of upper tropospheric water vapor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, R S -- Popp, P J -- Fahey, D W -- Marcy, T P -- Herman, R L -- Weinstock, E M -- Baumgardner, D G -- Garrett, T J -- Rosenlof, K H -- Thompson, T L -- Bui, P T -- Ridley, B A -- Wofsy, S C -- Toon, O B -- Tolbert, M A -- Karcher, B -- Peter, Th -- Hudson, P K -- Weinheimer, A J -- Heymsfield, A J -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):516-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Aeronomy Laboratory, National Oceanic and Atmospheric Administration, Boulder, CO 80305, USA. rgao@al.noaa.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14739457" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2004-07-27
    Description: Psychologists, economists, and advertising moguls have long known that human decision-making is strongly influenced by the behavior of others. A rapidly accumulating body of evidence suggests that the same is true in animals. Individuals can use information arising from cues inadvertently produced by the behavior of other individuals with similar requirements. Many of these cues provide public information about the quality of alternatives. The use of public information is taxonomically widespread and can enhance fitness. Public information can lead to cultural evolution, which we suggest may then affect biological evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Danchin, Etienne -- Giraldeau, Luc-Alain -- Valone, Thomas J -- Wagner, Richard H -- New York, N.Y. -- Science. 2004 Jul 23;305(5683):487-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.P.M.C.

    Complete genome sequence of the apicomplexan, Cryptosporidium parvum (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-03-27
    Description: The apicomplexan Cryptosporidium parvum is an intestinal parasite that affects healthy humans and animals, and causes an unrelenting infection in immunocompromised individuals such as AIDS patients. We report the complete genome sequence of C. parvum, type II isolate. Genome analysis identifies extremely streamlined metabolic pathways and a reliance on the host for nutrients. In contrast to Plasmodium and Toxoplasma, the parasite lacks an apicoplast and its genome, and possesses a degenerate mitochondrion that has lost its genome. Several novel classes of cell-surface and secreted proteins with a potential role in host interactions and pathogenesis were also detected. Elucidation of the core metabolism, including enzymes with high similarities to bacterial and plant counterparts, opens new avenues for drug development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abrahamsen, Mitchell S -- Templeton, Thomas J -- Enomoto, Shinichiro -- Abrahante, Juan E -- Zhu, Guan -- Lancto, Cheryl A -- Deng, Mingqi -- Liu, Chang -- Widmer, Giovanni -- Tzipori, Saul -- Buck, Gregory A -- Xu, Ping -- Bankier, Alan T -- Dear, Paul H -- Konfortov, Bernard A -- Spriggs, Helen F -- Iyer, Lakshminarayan -- Anantharaman, Vivek -- Aravind, L -- Kapur, Vivek -- U01 AI 46397/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):441-5.
