    LIII-Edge Anomalous X-ray Scattering by Cesium Measured with Synchrotron Radiation (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-07-21
    Description: Diffraction of monochromatized synchrotron radiation by crystals of cesium hydrogen tartrate has been used to measure the magnitude and phase of x-ray scattering for cesium near the LIII absorption edge. In this wavelength region the scattering amplitude of cesium is reduced by as much as 25 electrons per atom, compared to scattering of copper Kalpha x-rays. This change, which varies as a function of wavelength, affects the diffraction intensities in a manner similar to isomorphous substitution, and it is large enough to have promise for phase determination in the study of macromolecular structures. This experiment also demonstrates that accurate diffractometer measurements are possible with synchrotron radiation produced by an electron storage ring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, J C -- Templeton, D H -- Templeton, L K -- Hodgson, K O -- New York, N.Y. -- Science. 1978 Jul 21;201(4352):257-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17778657" target="_blank"〉PubMed〈/a〉

    An accurate geometric distance to the compact binary SS Cygni vindicates accretion disc theory (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-05-25
    Description: Dwarf novae are white dwarfs accreting matter from a nearby red dwarf companion. Their regular outbursts are explained by a thermal-viscous instability in the accretion disc, described by the disc instability model that has since been successfully extended to other accreting systems. However, the prototypical dwarf nova, SS Cygni, presents a major challenge to our understanding of accretion disc theory. At the distance of 159 +/- 12 parsecs measured by the Hubble Space Telescope, it is too luminous to be undergoing the observed regular outbursts. Using very long baseline interferometric radio observations, we report an accurate, model-independent distance to SS Cygni that places the source substantially closer at 114 +/- 2 parsecs. This reconciles the source behavior with our understanding of accretion disc theory in accreting compact objects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller-Jones, J C A -- Sivakoff, G R -- Knigge, C -- Kording, E G -- Templeton, M -- Waagen, E O -- New York, N.Y. -- Science. 2013 May 24;340(6135):950-2. doi: 10.1126/science.1237145.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉International Centre for Radio Astronomy Research, Curtin University, Perth, WA 6845, Australia. james.miller-jones@curtin.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23704566" target="_blank"〉PubMed〈/a〉

    Activation of SAPK/JNK by TNF receptor 1 through a noncytotoxic TRAF2-dependent pathway (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-10
    Description: Interaction of the p55 tumor necrosis factor receptor 1 (TNF-R1)-associated signal transducer TRADD with FADD signals apoptosis, whereas the TNF receptor-associated factor 2 protein (TRAF2) is required for activation of the nuclear transcription factor nuclear factor kappa B. TNF-induced activation of the stress-activated protein kinase (SAPK) was shown to occur through a noncytotoxic TRAF2-dependent pathway. TRAF2 was both sufficient and necessary for activation of SAPK by TNF-R1; conversely, expression of a dominant-negative FADD mutant, which blocks apoptosis, did not interfere with SAPK activation. Therefore, SAPK activation occurs through a pathway that is not required for TNF-R1-induced apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Natoli, G -- Costanzo, A -- Ianni, A -- Templeton, D J -- Woodgett, J R -- Balsano, C -- Levrero, M -- New York, N.Y. -- Science. 1997 Jan 10;275(5297):200-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fondazione Andrea Cesalpino and Istituto di I Clinica Medica, Policlinico Umberto I, Viale del Policlinico 155, 00161 Rome, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8985011" target="_blank"〉PubMed〈/a〉

    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.

    Allometry of alarm calls: black-capped chickadees encode information about predator size (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-06-25
    Description: Many animals produce alarm signals when they detect a potential predator, but we still know little about the information contained in these signals. Using presentations of 15 species of live predators, we show that acoustic features of the mobbing calls of black-capped chickadees (Poecile atricapilla) vary with the size of the predator. Companion playback experiments revealed that chickadees detect this information and that the intensity of mobbing behavior is related to the size and threat of the potential predator. This study demonstrates an unsuspected level of complexity and sophistication in avian alarm calls.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Templeton, Christopher N -- Greene, Erick -- Davis, Kate -- New York, N.Y. -- Science. 2005 Jun 24;308(5730):1934-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Sciences, University of Montana, Missoula, MT 59812, USA. ctemple2@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15976305" target="_blank"〉PubMed〈/a〉
