    Infrared Astronomy After IRAS (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-21
    Description: The 250,000 sources in the recently issued Infrared Astronomy Satellite (IRAS) all-sky infrared catalog are a challenge to astronomy. Many of these sources will be studied with existing and planned ground-based and airborne telescopes, but many others can no longer even be detected now that IRAS has ceased to operate. As anticipated by advisory panels of the National Academy of Sciences for a decade, study of the IRAS sources will require the Space Infrared Telescope Facility (SIRTF), a cooled, pointed telescope in space. This instrument may be the key to our understanding of cosmic birth-the formation of planets, stars, galaxies, active galactic nuclei, and quasars. Compared with IRAS and existing telescopes, SIRTF's power derives from a thousandfold gain in sensitivity over five octaves of the spectrum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rieke, G H -- Werner, M W -- Thompson, R I -- Becklin, E E -- Hoffmann, W F -- Houck, J R -- Low, F J -- Stein, W A -- Witteborn, F C -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):807-14.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17774074" target="_blank"〉PubMed〈/a〉

    Identification of hydroxymethanesulfonate in fog water (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-17
    Description: Previous studies have suggested that hydroxymethanesulfonate ion (HMSA) can be an important species in fog and cloud water. Formation of HMSA explains observed excesses of sulfur in the S(IV) state (+4 oxidation state) and formaldehyde (CH(2)O) in fogs and clouds. HMSA was determined in fog water by a novel ion-pairing chromatographic technique. Concentrations in samples collected in Bakersfield, California, within 5 kilometers of major sources of sulfur dioxide (SO(2)), were as high as 300 micromoles per liter. Total CH(2)O and S(IV) concentrations, which were measured independently, ranged from 10 to 200 and 5 to more than 300 micromoles per liter, respectively. Concentrations of CH(2)O, S(IV), and HMSA at Buttonwillow, California, which is 15 kilometers from the nearest source of SO(2), were less than those at Bakersfield but not absent. These data confirm that HMSA forms in atmospheric water droplets and can reach appreciable concentrations. HMSA represents an important source of acidity for water droplets and may also play a role in long-distance transport and transformation of SO(2).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Munger, J W -- Tiller, C -- Hoffmann, M R -- New York, N.Y. -- Science. 1986 Jan 17;231(4735):247-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17769644" target="_blank"〉PubMed〈/a〉

    Delay of disease development in transgenic plants that express the tobacco mosaic virus coat protein gene (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-09
    Description: A chimeric gene containing a cloned cDNA of the coat protein (CP) gene of tobacco mosaic virus (TMV) was introduced into tobacco cells on a Ti plasmid of Agrobacterium tumefaciens from which tumor inducing genes had been removed. Plants regenerated from transformed cells expressed TMV mRNA and CP as a nuclear trait. Seedlings from self-fertilized transgenic plants were inoculated with TMV and observed for development of disease symptoms. The seedlings that expressed the CP gene were delayed in symptom development and 10 to 60 percent of the transgenic plants failed to develop symptoms for the duration of the experiments. Increasing the concentration of TMV in the inoculum shortened the delay in appearance of symptoms. The results of these experiments indicate that plants can be genetically transformed for resistance to virus disease development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abel, P P -- Nelson, R S -- De, B -- Hoffmann, N -- Rogers, S G -- Fraley, R T -- Beachy, R N -- GM07067/GM/NIGMS NIH HHS/ -- GM08036/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 May 9;232(4751):738-43.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3457472" target="_blank"〉PubMed〈/a〉
