    Self-incompatibility: a self-recognition system in plants (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-16
    Description: Self-incompatibility (SI), a genetically controlled mechanism to prevent inbreeding in plants, offers a relatively simple model system for studying the interactions between plant cells or between a plant cell and the secreted product or products of another cell. Examples of two major types of SI, gametophytic and sporophytic, have been studied by cloning cDNAs corresponding to glycoproteins of the female tissues that segregate with particular variants encoded by the putative S locus. These secreted glycoproteins are envisaged to interact with the currently undescribed pollen component to cause arrest of pollen tube growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haring, V -- Gray, J E -- McClure, B A -- Anderson, M A -- Clarke, A E -- New York, N.Y. -- Science. 1990 Nov 16;250(4983):937-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Cell Biology Research Centre, School of Botany, University of Melbourne, Parkville, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2237440" target="_blank"〉PubMed〈/a〉

    Areawide suppression of European corn borer with Bt maize reaps savings to non-Bt maize growers (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-12
    Description: Transgenic maize engineered to express insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has become widely adopted in U.S. agriculture. In 2009, Bt maize was planted on more than 22.2 million hectares, constituting 63% of the U.S. crop. Using statistical analysis of per capita growth rate estimates, we found that areawide suppression of the primary pest Ostrinia nubilalis (European corn borer) is associated with Bt maize use. Cumulative benefits over 14 years are an estimated $3.2 billion for maize growers in Illinois, Minnesota, and Wisconsin, with more than $2.4 billion of this total accruing to non-Bt maize growers. Comparable estimates for Iowa and Nebraska are $3.6 billion in total, with $1.9 billion for non-Bt maize growers. These results affirm theoretical predictions of pest population suppression and highlight economic incentives for growers to maintain non-Bt maize refugia for sustainable insect resistance management.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hutchison, W D -- Burkness, E C -- Mitchell, P D -- Moon, R D -- Leslie, T W -- Fleischer, S J -- Abrahamson, M -- Hamilton, K L -- Steffey, K L -- Gray, M E -- Hellmich, R L -- Kaster, L V -- Hunt, T E -- Wright, R J -- Pecinovsky, K -- Rabaey, T L -- Flood, B R -- Raun, E S -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):222-5. doi: 10.1126/science.1190242.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Minnesota, St. Paul, MN 55108, USA. hutch002@umn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929774" target="_blank"〉PubMed〈/a〉

    Emission of coherent THz radiation from superconductors (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-11-24
    Description: Compact solid-state sources of terahertz (THz) radiation are being sought for sensing, imaging, and spectroscopy applications across the physical and biological sciences. We demonstrate that coherent continuous-wave THz radiation of sizable power can be extracted from intrinsic Josephson junctions in the layered high-temperature superconductor Bi2Sr2CaCu2O8. In analogy to a laser cavity, the excitation of an electromagnetic cavity resonance inside the sample generates a macroscopic coherent state in which a large number of junctions are synchronized to oscillate in phase. The emission power is found to increase as the square of the number of junctions reaching values of 0.5 microwatt at frequencies up to 0.85 THz, and persists up to approximately 50 kelvin. These results should stimulate the development of superconducting compact sources of THz radiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ozyuzer, L -- Koshelev, A E -- Kurter, C -- Gopalsami, N -- Li, Q -- Tachiki, M -- Kadowaki, K -- Yamamoto, T -- Minami, H -- Yamaguchi, H -- Tachiki, T -- Gray, K E -- Kwok, W-K -- Welp, U -- New York, N.Y. -- Science. 2007 Nov 23;318(5854):1291-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, Izmir Institute of Technology, TR-35430 Izmir, Turkey.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18033881" target="_blank"〉PubMed〈/a〉

    DNA tumor virus oncogenes antagonize the cGAS-STING DNA-sensing pathway (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-09-26
    Description: Cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) detects intracellular DNA and signals through the adapter protein STING to initiate the antiviral response to DNA viruses. Whether DNA viruses can prevent activation of the cGAS-STING pathway remains largely unknown. Here, we identify the oncogenes of the DNA tumor viruses, including E7 from human papillomavirus (HPV) and E1A from adenovirus, as potent and specific inhibitors of the cGAS-STING pathway. We show that the LXCXE motif of these oncoproteins, which is essential for blockade of the retinoblastoma tumor suppressor, is also important for antagonizing DNA sensing. E1A and E7 bind to STING, and silencing of these oncogenes in human tumor cells restores the cGAS-STING pathway. Our findings reveal a host-virus conflict that may have shaped the evolution of viral oncogenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lau, Laura -- Gray, Elizabeth E -- Brunette, Rebecca L -- Stetson, Daniel B -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):568-71. doi: 10.1126/science.aab3291.

    Prenatal exposure to the herbicide 2,4-dichlorophenyl-p-nitrophenyl ether destroys the rodent Harderian gland (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-15
    Description: Exposure of mice to the herbicide 2,4-dichlorophenyl-p-nitrophenyl ether during gestation produces abnormalities that are not readily apparent at birth but become obvious as the pups mature. By 2 weeks after birth there are severe intraorbital defects resulting from destruction of the Harderian glands behind the eyes. This effect is noticeable only postnatally because the Harderian gland does not grow or function until after birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, L E Jr -- Kavlock, R J -- Chernoff, N -- Ferrell, J -- McLamb, J -- Ostby, J -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):293-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053576" target="_blank"〉PubMed〈/a〉

    Nanostructure, osteopontin, and mechanical properties of calcitic avian eggshell (2018)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2018-03-31
    Description: Avian (and formerly dinosaur) eggshells form a hard, protective biomineralized chamber for embryonic growth—an evolutionary strategy that has existed for hundreds of millions of years. We show in the calcitic chicken eggshell how the mineral and organic phases organize hierarchically across different length scales and how variation in nanostructure across the shell thickness modifies its hardness, elastic modulus, and dissolution properties. We also show that the nanostructure changes during egg incubation, weakening the shell for chick hatching. Nanostructure and increased hardness were reproduced in synthetic calcite crystals grown in the presence of the prominent eggshell protein osteopontin. These results demonstrate the contribution of nanostructure to avian eggshell formation, mechanical properties, and dissolution.
