    Dispersal ability and climate change [Ecology] (2012)
    National Academy of Sciences
    Details
    Publication Date: 2012-05-30
    Description: As they have in response to past climatic changes, many species will shift their distributions in response to modern climate change. However, due to the unprecedented rapidity of projected climatic changes, some species may not be able to move their ranges fast enough to track shifts in suitable climates and associated habitats. Here, we investigate the ability of 493 mammals to keep pace with projected climatic changes in the Western Hemisphere. We modeled the velocities at which species will likely need to move to keep pace with projected changes in suitable climates. We compared these velocities with the velocities at which species are able to move as a function of dispersal distances and dispersal frequencies. Across the Western Hemisphere, on average, 9.2% of mammals at a given location will likely be unable to keep pace with climate change. In some places, up to 39% of mammals may be unable to track shifts in suitable climates. Eighty-seven percent of mammalian species are expected to experience reductions in range size and 20% of these range reductions will likely be due to limited dispersal abilities as opposed to reductions in the area of suitable climate. Because climate change will likely outpace the response capacity of many mammals, mammalian vulnerability to climate change may be more extensive than previously anticipated.

    Fe I oscillator strengths for the Gaia-ESO survey (2014)
    Oxford University Press
    Details
    Publication Date: 2014-05-31
    Description: The Gaia-ESO Public Spectroscopic Survey (GES) is conducting a large-scale study of multi-element chemical abundances of some 100 000 stars in the Milky Way with the ultimate aim of quantifying the formation history and evolution of young, mature and ancient Galactic populations. However, in preparing for the analysis of GES spectra, it has been noted that atomic oscillator strengths of important Fe  i lines required to correctly model stellar line intensities are missing from the atomic data base. Here, we present new experimental oscillator strengths derived from branching fractions and level lifetimes, for 142 transitions of Fe  i between 3526 and 10 864 Å, of which at least 38 are urgently needed by GES. We also assess the impact of these new data on solar spectral synthesis and demonstrate that for 36 lines that appear unblended in the Sun, Fe abundance measurements yield a small line-by-line scatter (0.08 dex) with a mean abundance of 7.44 dex in good agreement with recent publications.

    ASTROBIOLOGY: Ames's Proposal for Lab Triggers Battle at NASA (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-09-11
    Description: Officials at NASA's Ames Research Center in Moffett Field, California, would like to trade the use of part of their land for a new building largely dedicated to NASA's nascent astrobiology program, the core of which is a 2-year-old virtual institute based at Ames. Although some scientists applaud the idea, others say that it undermines the idea of a virtual institute and that operating costs would take money away from higher priorities. Two panels have offered conflicting opinions, which may be aired at a meeting next week.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lawler, A -- New York, N.Y. -- Science. 2000 Jul 7;289(5476):23a.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17832956" target="_blank"〉PubMed〈/a〉

    ASIAN-AMERICAN SCIENTISTS: Lee Case Births a Reluctant Activist (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-31
    Description: Until the past year, Alex Chao, a senior physicist at the Stanford Linear Accelerator Center, tended to keep his views to himself. But the Wen Ho Lee case turned Chao into a reluctant activist who has contributed money for Lee's defense, helped organize rallies in the San Francisco Bay area, and talked to his neighbors about the injustice he believes Lee and other Asian Americans have suffered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lawler, A -- New York, N.Y. -- Science. 2000 Nov 10;290(5494):1073.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17743249" target="_blank"〉PubMed〈/a〉

    ASIAN-AMERICAN SCIENTISTS: Silent No Longer: 'Model Minority' Mobilizes (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-31
    Description: Angered and emboldened by the Wen Ho Lee case, many Asian-American researchers at national laboratories are decrying their status as "high-tech coolies"--and demanding change. It's a sudden and surprising turn of events for a community that traditionally has avoided political organization, legal recourse, and conflict with authority. And given the growing numerical muscle of Asian Americans in both public and private labs, the budding movement--if sustained--will be felt far beyond the secure fences of the Department of Energy's weapons labs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lawler, A -- New York, N.Y. -- Science. 2000 Nov 10;290(5494):1072-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17743248" target="_blank"〉PubMed〈/a〉
