    Common Kibra alleles are associated with human memory performance (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-10-21
    Beschreibung: Human memory is a polygenic trait. We performed a genome-wide screen to identify memory-related gene variants. A genomic locus encoding the brain protein KIBRA was significantly associated with memory performance in three independent, cognitively normal cohorts from Switzerland and the United States. Gene expression studies showed that KIBRA was expressed in memory-related brain structures. Functional magnetic resonance imaging detected KIBRA allele-dependent differences in hippocampal activations during memory retrieval. Evidence from these experiments suggests a role for KIBRA in human memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Papassotiropoulos, Andreas -- Stephan, Dietrich A -- Huentelman, Matthew J -- Hoerndli, Frederic J -- Craig, David W -- Pearson, John V -- Huynh, Kim-Dung -- Brunner, Fabienne -- Corneveaux, Jason -- Osborne, David -- Wollmer, M Axel -- Aerni, Amanda -- Coluccia, Daniel -- Hanggi, Jurgen -- Mondadori, Christian R A -- Buchmann, Andreas -- Reiman, Eric M -- Caselli, Richard J -- Henke, Katharina -- de Quervain, Dominique J-F -- P30AG19610/AG/NIA NIH HHS/ -- R01MH057899/MH/NIMH NIH HHS/ -- U01-HL086528-01/HL/NHLBI NIH HHS/ -- U24NS051872/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):475-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Psychiatry Research, University of Zurich, Zurich 8057, Switzerland. papas@bli.unizh.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053149" target="_blank"〉PubMed〈/a〉

    Planktonic foraminifera of the California Current reflect 20th-century warming (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-01-10
    Beschreibung: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability. We report variations in planktonic foraminifera from varved sediments off southern California spanning the past 1400 years. Increasing abundances of tropical/subtropical species throughout the 20th century reflect a warming trend superimposed on decadal-scale fluctuations. Decreasing abundances of temperate/subpolar species in the late 20th century indicate a deep, penetrative warming not observed in previous centuries. These results imply that 20th-century warming, apparently anthropogenic, has already affected lower trophic levels of the California Current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Field, David B -- Baumgartner, Timothy R -- Charles, Christopher D -- Ferreira-Bartrina, Vicente -- Ohman, Mark D -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093, USA. dfield@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400144" target="_blank"〉PubMed〈/a〉

    MC1R germline variants confer risk for BRAF-mutant melanoma (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-07-01
    Beschreibung: Germline variants in MC1R, the gene encoding the melanocortin-1 receptor, and sun exposure increase risk for melanoma in Caucasians. The majority of melanomas that occur on skin with little evidence of chronic sun-induced damage (non-CSD melanoma) have mutations in the BRAF oncogene, whereas in melanomas on skin with marked CSD (CSD melanoma) these mutations are less frequent. In two independent Caucasian populations, we show that MC1R variants are strongly associated with BRAF mutations in non-CSD melanomas. In this tumor subtype, the risk for melanoma associated with MC1R is due to an increase in risk of developing melanomas with BRAF mutations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landi, Maria Teresa -- Bauer, Jurgen -- Pfeiffer, Ruth M -- Elder, David E -- Hulley, Benjamin -- Minghetti, Paola -- Calista, Donato -- Kanetsky, Peter A -- Pinkel, Daniel -- Bastian, Boris C -- K07 CA80700/CA/NCI NIH HHS/ -- P01 CA025874-25-A1/CA/NCI NIH HHS/ -- R01 CA5558/CA/NCI NIH HHS/ -- R01 CA94963/CA/NCI NIH HHS/ -- R33 CA95300/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 28;313(5786):521-2.

    Long-term sustainability of a high-energy, low-diversity crustal biome (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-10-21
    Beschreibung: Geochemical, microbiological, and molecular analyses of alkaline saline groundwater at 2.8 kilometers depth in Archaean metabasalt revealed a microbial biome dominated by a single phylotype affiliated with thermophilic sulfate reducers belonging to Firmicutes. These sulfate reducers were sustained by geologically produced sulfate and hydrogen at concentrations sufficient to maintain activities for millions of years with no apparent reliance on photosynthetically derived substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Li-Hung -- Wang, Pei-Ling -- Rumble, Douglas -- Lippmann-Pipke, Johanna -- Boice, Erik -- Pratt, Lisa M -- Sherwood Lollar, Barbara -- Brodie, Eoin L -- Hazen, Terry C -- Andersen, Gary L -- DeSantis, Todd Z -- Moser, Duane P -- Kershaw, Dave -- Onstott, T C -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):479-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, Princeton University, Princeton, NJ, USA. lhlin@ntu.edu.tw〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053150" target="_blank"〉PubMed〈/a〉

    Beschreibung: The analysis of Madin et al. (Reports, 12 May 2006, p. 897) of Phanerozoic diversity failed to support expected correlations between carnivores and noncarnivores, leading the authors to reject escalation as an important macroevolutionary process.

    Opposing effects of native and exotic herbivores on plant invasions (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-03-11
    Beschreibung: Exotic species are widely assumed to thrive because they lack natural enemies in their new ranges. However, a meta-analysis of 63 manipulative field studies including more than 100 exotic plant species revealed that native herbivores suppressed exotic plants, whereas exotic herbivores facilitated both the abundance and species richness of exotic plants. Both outcomes suggest that plants are especially susceptible to novel, generalist herbivores that they have not been selected to resist. Thus, native herbivores provide biotic resistance to plant invasions, but the widespread replacement of native with exotic herbivores eliminates this ecosystem service, facilitates plant invasions, and triggers an invasional "meltdown."〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, John D -- Burkepile, Deron E -- Hay, Mark E -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1459-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biology, Georgia Institute of Technology, Atlanta, GA 30332, USA. jdp52@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527979" target="_blank"〉PubMed〈/a〉
