    Suppression predicts working memory capacity [Psychological and Cognitive Sciences] (2016)
    National Academy of Sciences
    Details
    Publication Date: 2016-03-30
    Description: According to contemporary accounts of visual working memory (vWM), the ability to efficiently filter relevant from irrelevant information contributes to an individual’s overall vWM capacity. Although there is mounting evidence for this hypothesis, very little is known about the precise filtering mechanism responsible for controlling access to vWM and for...

    Arabidopsis NPH1: a flavoprotein with the properties of a photoreceptor for phototropism (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-11-30
    Description: The NPH1 gene of Arabidopsis thaliana encodes a 120-kilodalton serine-threonine protein kinase hypothesized to function as a photoreceptor for phototropism. When expressed in insect cells, the NPH1 protein is phosphorylated in response to blue light irradiation. The biochemical and photochemical properties of the photosensitive protein reflect those of the native protein in microsomal membranes. Recombinant NPH1 noncovalently binds flavin mononucleotide, a likely chromophore for light-dependent autophosphorylation. The fluorescence excitation spectrum of the recombinant protein is similar to the action spectrum for phototropism, consistent with the conclusion that NPH1 is an autophosphorylating flavoprotein photoreceptor mediating phototropic responses in higher plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christie, J M -- Reymond, P -- Powell, G K -- Bernasconi, P -- Raibekas, A A -- Liscum, E -- Briggs, W R -- New York, N.Y. -- Science. 1998 Nov 27;282(5394):1698-701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution of Washington, 260 Panama Street, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9831559" target="_blank"〉PubMed〈/a〉

    Observational evidence for a possible new diffusion path (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-01-04
    Description: Transmission electron microscopy of experimentally deformed amphibolite suggests that submicroscopic intracrystalline tubes formed around linear defects may be a previously unrecognized kind of diffusion pathway. Deformed and compositionally altered plagioclase and amphibole crystals include moderate densities of linear defects that morphologically resemble unit dislocations but display unusual contrast. During prolonged electron irradiation, the core regions of the defects expand to well-defined tubes that are approximately 20 nanometers in diameter. Both observations suggest that the regions about the defect cores are glassy and were filled with silicate-water fluid during the experiments. Intracrystalline transport along these tubes would likely be several orders of magnitude faster than traditionally conceived processes of solid-state volume diffusion, grain-boundary solvent transfer, and ordinary pipe diffusion along dislocation cores.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hacker, B R -- Christie, J M -- New York, N.Y. -- Science. 1991 Jan 4;251(4989):67-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17778603" target="_blank"〉PubMed〈/a〉

    Plant UVR8 photoreceptor senses UV-B by tryptophan-mediated disruption of cross-dimer salt bridges (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-11
    Description: The recently identified plant photoreceptor UVR8 (UV RESISTANCE LOCUS 8) triggers regulatory changes in gene expression in response to ultraviolet-B (UV-B) light through an unknown mechanism. Here, crystallographic and solution structures of the UVR8 homodimer, together with mutagenesis and far-UV circular dichroism spectroscopy, reveal its mechanisms for UV-B perception and signal transduction. beta-propeller subunits form a remarkable, tryptophan-dominated, dimer interface stitched together by a complex salt-bridge network. Salt-bridging arginines flank the excitonically coupled cross-dimer tryptophan "pyramid" responsible for UV-B sensing. Photoreception reversibly disrupts salt bridges, triggering dimer dissociation and signal initiation. Mutation of a single tryptophan to phenylalanine retunes the photoreceptor to detect UV-C wavelengths. Our analyses establish how UVR8 functions as a photoreceptor without a prosthetic chromophore to promote plant development and survival in sunlight.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3505452/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3505452/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christie, John M -- Arvai, Andrew S -- Baxter, Katherine J -- Heilmann, Monika -- Pratt, Ashley J -- O'Hara, Andrew -- Kelly, Sharon M -- Hothorn, Michael -- Smith, Brian O -- Hitomi, Kenichi -- Jenkins, Gareth I -- Getzoff, Elizabeth D -- GM37684/GM/NIGMS NIH HHS/ -- R01 GM037684/GM/NIGMS NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1492-6. doi: 10.1126/science.1218091.

    Optogenetics. Engineering of a light-gated potassium channel (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-05-09
    Description: The present palette of opsin-based optogenetic tools lacks a light-gated potassium (K(+)) channel desirable for silencing of excitable cells. Here, we describe the construction of a blue-light-induced K(+) channel 1 (BLINK1) engineered by fusing the plant LOV2-Jalpha photosensory module to the small viral K(+) channel Kcv. BLINK1 exhibits biophysical features of Kcv, including K(+) selectivity and high single-channel conductance but reversibly photoactivates in blue light. Opening of BLINK1 channels hyperpolarizes the cell to the K(+) equilibrium potential. Ectopic expression of BLINK1 reversibly inhibits the escape response in light-exposed zebrafish larvae. BLINK1 therefore provides a single-component optogenetic tool that can establish prolonged, physiological hyperpolarization of cells at low light intensities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cosentino, Cristian -- Alberio, Laura -- Gazzarrini, Sabrina -- Aquila, Marco -- Romano, Edoardo -- Cermenati, Solei -- Zuccolini, Paolo -- Petersen, Jan -- Beltrame, Monica -- Van Etten, James L -- Christie, John M -- Thiel, Gerhard -- Moroni, Anna -- BB/J016047/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/M002128/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 May 8;348(6235):707-10. doi: 10.1126/science.aaa2787.

    Subsolidus reactions in lunar pyroxenes: An electron petrographic study (1975)
    Springer
    Contributions to mineralogy and petrology 51 (1975), S. 263-281

    ISSN: 1432-0967

    Topics: Geosciences
    Notes: Abstract Zoned lunar pyroxenes have been examined by high voltage (800–1000 kV) transmission electron microscopy and electron diffraction, with the particular aim of providing information on the cooling history of individual pyroxenes. Microstructures resulting from composition discontinuities occurring during continuous crystallization, exsolution lamellae of pigeonite and augite and the development of “denuded” zones, and anti-phase domains (APD's) in pigeonite have been studied with respect to their scale, morphology and micro-structural evolution. These features have been further interpreted with respect to a proposed pseudobinary phase diagram of constant En/Fs. Information found to be the most useful for determining cooling rates in pyroxenes are: Δβ for quickly cooled rocks; microstructural evolution and APD size for moderately cooled rocks; and denuded zone widths and APD morphology for slowly cooled rocks.

    Notes: Abstract A new chemical etching technique has been developed to study defect structures in terrestrial and lunar olivine crystals. Dislocations, low-angle dislocation boundaries, dislocation arrays and pile-ups have been observed on the (010, (100), and (001) faces of both polished and cleaved naturally deformed single crystal olivine, on various orientations of crystals in dunite, and in an experimentally deformed olivine crystal. Etching of Apollo 12 igneous rocks revealed dislocations and radiation damage tracks in lunar olivine. Dislocation etching of the (001) face of olivine is reported for the first time in this paper.

    Exsolution in terrestrial and lunar plagioclases revealed by chemical etching (1978)
    Springer
    Contributions to mineralogy and petrology 65 (1978), S. 283-291 
    Details

    Topics: Geosciences
    Notes: Abstract A new chemical etching technique reveals fine scale exsolution structures on polished surfaces of plagioclases in the bytownite and labradorite range. A very obvious blue and locally brown stain is produced (by the action of citric acid) in growth zones of a restricted range of compositions on etched surfaces. The blue-stained zones contain very fine grooves, corresponding to the traces of thin exsolution lamellae. Exsolution features have been revealed in this way in plagioclases in a terrestrial diabase, lunar basalts and an amphibolite. Compositions of the exsolved areas found by microprobe analysis represent averages of the matrix and exsolution lamellae. Analytical methods with higher spatial resolution are required to determine the composition of the lamellae. This etching method permits easy optical identification of compositional zoning and of fine scale exsolution over relatively large areas and is therefore complementary to other techniques.
