    Regulatory role of parasites: impact on host population shifts with resource availability (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-12
    Description: Effects of infections by the ciliate Lambornella clarki on larval populations of its mosquito host Aedes sierrensis were examined in laboratory and field studies. When host populations developed with sufficient food, mortality from parasites was additive and reduced the number of emerging mosquitoes. For food-limited populations, mortality was compensatory or depensatory; emerging adults were as or more abundant with higher average fitness than those from uninfected control populations. When nutrients were scarce, parasitic infections relaxed larval competition and increased per capita food by reducing host abundance. Food limitation altered larval feeding behavior, reducing horizontal transmission and subsequent mortality from parasitism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Washburn, J O -- Mercer, D R -- Anderson, J R -- AI20245/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):185-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1906637" target="_blank"〉PubMed〈/a〉

    Microcephalin, a gene regulating brain size, continues to evolve adaptively in humans (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-10
    Description: The gene Microcephalin (MCPH1) regulates brain size and has evolved under strong positive selection in the human evolutionary lineage. We show that one genetic variant of Microcephalin in modern humans, which arose approximately 37,000 years ago, increased in frequency too rapidly to be compatible with neutral drift. This indicates that it has spread under strong positive selection, although the exact nature of the selection is unknown. The finding that an important brain gene has continued to evolve adaptively in anatomically modern humans suggests the ongoing evolutionary plasticity of the human brain. It also makes Microcephalin an attractive candidate locus for studying the genetics of human variation in brain-related phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Evans, Patrick D -- Gilbert, Sandra L -- Mekel-Bobrov, Nitzan -- Vallender, Eric J -- Anderson, Jeffrey R -- Vaez-Azizi, Leila M -- Tishkoff, Sarah A -- Hudson, Richard R -- Lahn, Bruce T -- New York, N.Y. -- Science. 2005 Sep 9;309(5741):1717-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Human Genetics, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16151009" target="_blank"〉PubMed〈/a〉

    Entangled macroscopic quantum States in two superconducting qubits (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-17
    Description: We present spectroscopic evidence for the creation of entangled macroscopic quantum states in two current-biased Josephson-junction qubits coupled by a capacitor. The individual junction bias currents are used to control the interaction between the qubits by tuning the energy level spacings of the junctions in and out of resonance with each other. Microwave spectroscopy in the 4 to 6 gigahertzrange at 20 millikelvin reveals energy levels that agree well with theoretical results for entangled states. The single qubits are spatially separate, and the entangled states extend over the 0.7-millimeter distance between the two qubits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berkley, A J -- Xu, H -- Ramos, R C -- Gubrud, M A -- Strauch, F W -- Johnson, P R -- Anderson, J R -- Dragt, A J -- Lobb, C J -- Wellstood, F C -- New York, N.Y. -- Science. 2003 Jun 6;300(5625):1548-50.

    Ongoing adaptive evolution of ASPM, a brain size determinant in Homo sapiens (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-10
    Description: The gene ASPM (abnormal spindle-like microcephaly associated) is a specific regulator of brain size, and its evolution in the lineage leading to Homo sapiens was driven by strong positive selection. Here, we show that one genetic variant of ASPM in humans arose merely about 5800 years ago and has since swept to high frequency under strong positive selection. These findings, especially the remarkably young age of the positively selected variant, suggest that the human brain is still undergoing rapid adaptive evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mekel-Bobrov, Nitzan -- Gilbert, Sandra L -- Evans, Patrick D -- Vallender, Eric J -- Anderson, Jeffrey R -- Hudson, Richard R -- Tishkoff, Sarah A -- Lahn, Bruce T -- New York, N.Y. -- Science. 2005 Sep 9;309(5741):1720-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Human Genetics, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16151010" target="_blank"〉PubMed〈/a〉

    Predator-induced trophic shift of a free-living ciliate: parasitism of mosquito larvae by their prey (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-05-27
    Description: Larvae of the treehole mosquito, Aedes sierrensis, release a waterborne factor that induces morphogenesis of one of their prey, the tetrahymenid ciliate Lambornella clarki. Induced free-living trophonts of L. clarki undergo a synchronous response in which cells divide and transform into parasitic cells (theronts) that encyst on larval predators. Parasitic ciliates penetrate the cuticle, enter the hemocoel, and ultimately kill their predator-host. In nature, this trophic shift can lead to predator extinction and dramatic changes in microbial populations. Facultative parasitism by this polymorphic ciliate may have evolved as an antipredator strategy. The experimentally inducible parasitic response of L. clarki provides a novel model for studying cellular morphogenesis of ciliated protozoa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Washburn, J O -- Gross, M E -- Mercer, D R -- Anderson, J R -- AI20245/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1988 May 27;240(4856):1193-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomological Sciences, University of California, Berkely 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3131877" target="_blank"〉PubMed〈/a〉

    Brown carbon spheres in East Asian outflow and their optical properties (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-09
    Description: Atmospheric aerosols play a substantial role in climate change through radiative forcing. Combustion-produced carbonaceous particles are the main light-absorbing aerosols; thus, quantifying their optical properties is essential for determining the magnitude of direct forcing. By using the electron energy-loss spectrum in the transmission electron microscope, we quantified the optical properties of individual, submicrometer amorphous carbon spheres that are ubiquitous in East Asian-Pacific outflow. The data indicate that these common spheres are brown, not black, with a mean refractive index of 1.67 - 0.27i (where i = square root 1) at a wavelength of 550 nanometers. The results suggest that brown carbon aerosols should be explicitly included in radiative forcing models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alexander, Duncan T L -- Crozier, Peter A -- Anderson, James R -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):833-6. doi: 10.1126/science.1155296.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉LeRoy Eyring Center for Solid State Science, Arizona State University, Post Office Box 871704, Tempe, AZ 85287, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687964" target="_blank"〉PubMed〈/a〉

    Retrieval of information from long-term memory (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-01
    Description: Information is represented in long-term memory as a network of associations among concepts. Information is retrieved by spreading activation from concepts in working memory through the network structure. The time required to retrieve information is a function of the level of activation that it achieves. Fanning of multiple paths from a node dissipates the activation the node sends down any path and increases retrieval time. Fan effects are reduced as subjects overlearn the material or when they can change their task from a recognition judgment to a consistency judgment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, J R -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):25-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828877" target="_blank"〉PubMed〈/a〉
