    High-Latitude Stratospheric Aerosols Measured by the SAM II Satellite System in 1978 and 1979 (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-16
    Description: Results of the first year of data collection by the SAM (Stratospheric Aerosol Measurement) II satellite system are presented. Almost 10,000 profiles of stratospheric aerosol extinction in the Arctic and Antarctic regions are used to construct plots of weekly averaged aerosol extinction versus altitude and time and stratospheric optical depth versus time. Corresponding temperature fields are presented. These data show striking similarities in the aerosol behavior for corresponding seasons. Wintertime polar stratospheric clouds that are strongly correlated with temperature are documented. They are much more prevalent in the Antarctic stratosphere during the cold austral winter and increase the stratospheric optical depths by as much as an order of magnitude for a period of about 2 months. These clouds might represent a sink for stratospheric water vapor and must be considered in the radiative budget for this region and time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCormick, M P -- Chu, W P -- Grams, G W -- Hamill, P -- Herman, B M -- McMaster, L R -- Pepin, T J -- Russell, P B -- Steele, H M -- Swissler, T J -- New York, N.Y. -- Science. 1981 Oct 16;214(4518):328-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17829788" target="_blank"〉PubMed〈/a〉

    Associative behavioral modification in hermissenda: cellular correlates (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-18
    Description: Three days of training consisting of trials of light paired with rotation produces a long-term modification of photopositive behavior in Hermissenda crassicornis. The behavioral modification depends on the temporal association of light and rotation. For animals that received light paired with rotation, significant increases in the spontaneous activity of type B photoreceptors were correlated with changes in photopositive behavior after training. A persistent tonic depolarization of type B photoreceptors can explain the cellular changes correlated with the long-term behavioral modification produced by the temporal association of light and rotation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crow, T J -- Alkon, D L -- New York, N.Y. -- Science. 1980 Jul 18;209(4454):412-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17747814" target="_blank"〉PubMed〈/a〉

    DDT contamination at Wheeler National Wildlife Refuge (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-25
    Description: Disposal of industrial waste resulted in massive DDT contamination at Wheeler National Wildlife Refuge, Alabama. Nearly a decade after the cessation of DDT manufacturing at the facility responsible, concentrations of DDT residues in the local fauna are still high enough to suggest avian reproductive impairment and mortality. Populations of fish-eating birds are low, endangered species are being exposed, and muscle lipids of game birds contain up to 6900 parts of DDT (isomers and metabolites) per million.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Shea, T J -- Fleming, W J -- Cromartie, E -- New York, N.Y. -- Science. 1980 Jul 25;209(4455):509-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7394517" target="_blank"〉PubMed〈/a〉

    Familial studies of intelligence: a review (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-29
    Description: A summary of 111 studies identified in a survey of the world literature on familial resemblances in measured intelligence reveals a profile of average correlations consistent with a polygenic mode of inheritance. There is, however, a marked degree of heterogeneity of the correlations within familial groupings, which is not moderated by sex of familial pairing or by type of intelligence test used.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bouchard, T J Jr -- McGue, M -- 5 T32 MH14647/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 May 29;212(4498):1055-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7195071" target="_blank"〉PubMed〈/a〉

    Associative learning in Aplysia: cellular correlates supporting a conditioned fear hypothesis (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-30
    Description: Aversive associative learning in Aplysia california survives restraint of the animal and surgical exposure of the central nervous system. The learning is expressed in the intracellularly recorded activity of identified motor neurons mediating three different defensive behaviors: escape locomotion, inking, and siphon withdrawal. In each case, animals that had previously received paired training showed significant facilitation of synaptic input to motor neurons during test stimulation in the presence of the conditioned stimulus. Animals without such training showed no facilitation of input to the motor neurons. Resting potential and input resistance appeared unaffected by conditioning and were not altered by application of the conditioned stimulus. These results show that the conditioned facilitation of defensive responses cannot be explained by subthreshold actions of the conditioned stimulus on the motor neurons and support the hypothesis that Aplysia learn to associate the conditioned stimulus with a fearlike central state.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carew, T J -- Walters, E T -- Kandel, E R -- 5K02MH0081/MH/NIMH NIH HHS/ -- 5K05MH18558/MH/NIMH NIH HHS/ -- 5T32MH1574/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):501-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455692" target="_blank"〉PubMed〈/a〉

    Associative Learning in Aplysia: evidence for conditioned fear in an invertebrate (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-30
    Description: Aversive classical conditioning of Aplysia californica, a gastropod mollusk suited for neurobiological study, produces a learned reaction to the chemosensory conditioned stimulus that is expressed as a marked facilitation of four defensive responses: two graded reflexes (head and siphon withdrawal), an all-or-none fixed act (inking), and a complex fixed action pattern (escape locomotion). In addition, the conditioned stimulus produces a concomitant depression of at least one appetitive response, feeding. These extensive and selective actions of the conditioned stimulus in Aplysia resemble the actions of conditioned fear stimuli in higher mammals and suggest that the functional equivalent of fear occurs in invertebrates and thus may be an adaptive mechanism that is widespread in the animal kingdom.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walters, E T -- Carew, T J -- Kandel, E R -- 5K02MH0081/MH/NIMH NIH HHS/ -- 5K05MH18558/MH/NIMH NIH HHS/ -- 5T32MH1574/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):504-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7192881" target="_blank"〉PubMed〈/a〉

    Rhodamine-123 selectively reduces clonal growth of carcinoma cells in vitro (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: Rhodamine-123, a cationic laser dye, markedly reduced the clonal growth of carcinoma cells but had little effect on nontumorigenic epithelial cells in vitro. This selective inhibitory effect of Rhodamine-123 on some carcinomas is unusual since known anticancer drugs, such as arabinosyl cytosine and methotrexate, have not been shown to exhibit such selectivity in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernal, S D -- Lampidis, T J -- Summerhayes, I C -- Chen, L B -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1117-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146897" target="_blank"〉PubMed〈/a〉
