    Description: Energetic young pulsars and expanding blast waves [supernova remnants (SNRs)] are the most visible remains after massive stars, ending their lives, explode in core-collapse supernovae. The Fermi Gamma-Ray Space Telescope has unveiled a radio quiet pulsar located near the center of the compact synchrotron nebula inside the supernova remnant CTA 1. The pulsar, discovered through its gamma-ray pulsations, has a period of 316.86 milliseconds and a period derivative of 3.614 x 10(-13) seconds per second. Its characteristic age of 10(4) years is comparable to that estimated for the SNR. We speculate that most unidentified Galactic gamma-ray sources associated with star-forming regions and SNRs are such young pulsars.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdo, A A -- Ackermann, M -- Atwood, W B -- Baldini, L -- Ballet, J -- Barbiellini, G -- Baring, M G -- Bastieri, D -- Baughman, B M -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bogaert, G -- Bonamente, E -- Borgland, A W -- Bregeon, J -- Brez, A -- Brigida, M -- Bruel, P -- Burnett, T H -- Caliandro, G A -- Cameron, R A -- Caraveo, P A -- Carlson, P -- Casandjian, J M -- Cecchi, C -- Charles, E -- Chekhtman, A -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cohen-Tanugi, J -- Cominsky, L R -- Conrad, J -- Cutini, S -- Davis, D S -- Dermer, C D -- de Angelis, A -- de Palma, F -- Digel, S W -- Dormody, M -- do Couto E Silva, E -- Drell, P S -- Dubois, R -- Dumora, D -- Edmonds, Y -- Farnier, C -- Focke, W B -- Fukazawa, Y -- Funk, S -- Fusco, P -- Gargano, F -- Gasparrini, D -- Gehrels, N -- Germani, S -- Giebels, B -- Giglietto, N -- Giordano, F -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grondin, M-H -- Grove, J E -- Guillemot, L -- Guiriec, S -- Harding, A K -- Hartman, R C -- Hays, E -- Hughes, R E -- Johannesson, G -- Johnson, A S -- Johnson, R P -- Johnson, T J -- Johnson, W N -- Kamae, T -- Kanai, Y -- Kanbach, G -- Katagiri, H -- Kawai, N -- Kerr, M -- Kishishita, T -- Kiziltan, B -- Knodlseder, J -- Kocian, M L -- Komin, N -- Kuehn, F -- Kuss, M -- Latronico, L -- Lemoine-Goumard, M -- Longo, F -- Lonjou, V -- Loparco, F -- Lott, B -- Lovellette, M N -- Lubrano, P -- Makeev, A -- Marelli, M -- Mazziotta, M N -- McEnery, J E -- McGlynn, S -- Meurer, C -- Michelson, P F -- Mineo, T -- Mitthumsiri, W -- Mizuno, T -- Moiseev, A A -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nakamori, T -- Nolan, P L -- Nuss, E -- Ohno, M -- Ohsugi, T -- Okumura, A -- Omodei, N -- Orlando, E -- Ormes, J F -- Ozaki, M -- Paneque, D -- Panetta, J H -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Piano, G -- Pieri, L -- Piron, F -- Porter, T A -- Raino, S -- Rando, R -- Ray, P S -- Razzano, M -- Reimer, A -- Reimer, O -- Reposeur, T -- Ritz, S -- Rochester, L S -- Rodriguez, A Y -- Romani, R W -- Roth, M -- Ryde, F -- Sadrozinski, H F-W -- Sanchez, D -- Sander, A -- Parkinson, P M Saz -- Schalk, T L -- Sellerholm, A -- Sgro, C -- Siskind, E J -- Smith, D A -- Smith, P D -- Spandre, G -- Spinelli, P -- Starck, J-L -- Strickman, M S -- Suson, D J -- Tajima, H -- Takahashi, H -- Takahashi, T -- Tanaka, T -- Thayer, J B -- Thayer, J G -- Thompson, D J -- Thorsett, S E -- Tibaldo, L -- Torres, D F -- Tosti, G -- Tramacere, A -- Usher, T L -- Van Etten, A -- Vilchez, N -- Vitale, V -- Wang, P -- Watters, K -- Winer, B L -- Wood, K S -- Yasuda, H -- Ylinen, T -- Ziegler, M -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1218-21. doi: 10.1126/science.1165572.

    Description: Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mechanisms driving diversity and endemism across systems. Compared with land species, threat levels are higher among marine mammals, driven by different processes (accidental mortality and pollution, rather than habitat loss), and are spatially distinct (peaking in northern oceans, rather than in Southeast Asia). Marine mammals are also disproportionately poorly known. These data are made freely available to support further scientific developments and conservation action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schipper, Jan -- Chanson, Janice S -- Chiozza, Federica -- Cox, Neil A -- Hoffmann, Michael -- Katariya, Vineet -- Lamoreux, John -- Rodrigues, Ana S L -- Stuart, Simon N -- Temple, Helen J -- Baillie, Jonathan -- Boitani, Luigi -- Lacher, Thomas E Jr -- Mittermeier, Russell A -- Smith, Andrew T -- Absolon, Daniel -- Aguiar, John M -- Amori, Giovanni -- Bakkour, Noura -- Baldi, Ricardo -- Berridge, Richard J -- Bielby, Jon -- Black, Patricia Ann -- Blanc, J Julian -- Brooks, Thomas M -- Burton, James A -- Butynski, Thomas M -- Catullo, Gianluca -- Chapman, Roselle -- Cokeliss, Zoe -- Collen, Ben -- Conroy, Jim -- Cooke, Justin G -- da Fonseca, Gustavo A B -- Derocher, Andrew E -- Dublin, Holly T -- Duckworth, J W -- Emmons, Louise -- Emslie, Richard H -- Festa-Bianchet, Marco -- Foster, Matt -- Foster, Sabrina -- Garshelis, David L -- Gates, Cormack -- Gimenez-Dixon, Mariano -- Gonzalez, Susana -- Gonzalez-Maya, Jose Fernando -- Good, Tatjana C -- Hammerson, Geoffrey -- Hammond, Philip S -- Happold, David -- Happold, Meredith -- Hare, John -- Harris, Richard B -- Hawkins, Clare E -- Haywood, Mandy -- Heaney, Lawrence R -- Hedges, Simon -- Helgen, Kristofer M -- Hilton-Taylor, Craig -- Hussain, Syed Ainul -- Ishii, Nobuo -- Jefferson, Thomas A -- Jenkins, Richard K B -- Johnston, Charlotte H -- Keith, Mark -- Kingdon, Jonathan -- Knox, David H -- Kovacs, Kit M -- Langhammer, Penny -- Leus, Kristin -- Lewison, Rebecca -- Lichtenstein, Gabriela -- Lowry, Lloyd F -- Macavoy, Zoe -- Mace, Georgina M -- Mallon, David P -- Masi, Monica -- McKnight, Meghan W -- Medellin, Rodrigo A -- Medici, Patricia -- Mills, Gus -- Moehlman, Patricia D -- Molur, Sanjay -- Mora, Arturo -- Nowell, Kristin -- Oates, John F -- Olech, Wanda -- Oliver, William R L -- Oprea, Monik -- Patterson, Bruce D -- Perrin, William F -- Polidoro, Beth A -- Pollock, Caroline -- Powel, Abigail -- Protas, Yelizaveta -- Racey, Paul -- Ragle, Jim -- Ramani, Pavithra -- Rathbun, Galen -- Reeves, Randall R -- Reilly, Stephen B -- Reynolds, John E 3rd -- Rondinini, Carlo -- Rosell-Ambal, Ruth Grace -- Rulli, Monica -- Rylands, Anthony B -- Savini, Simona -- Schank, Cody J -- Sechrest, Wes -- Self-Sullivan, Caryn -- Shoemaker, Alan -- Sillero-Zubiri, Claudio -- De Silva, Naamal -- Smith, David E -- Srinivasulu, Chelmala -- Stephenson, Peter J -- van Strien, Nico -- Talukdar, Bibhab Kumar -- Taylor, Barbara L -- Timmins, Rob -- Tirira, Diego G -- Tognelli, Marcelo F -- Tsytsulina, Katerina -- Veiga, Liza M -- Vie, Jean-Christophe -- Williamson, Elizabeth A -- Wyatt, Sarah A -- Xie, Yan -- Young, Bruce E -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):225-30. doi: 10.1126/science.1165115.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉International Union for Conservation of Nature (IUCN) Species Programme, IUCN, 28 Rue Mauverney, 1196 Gland, Switzerland. jan.schipper@iucn.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18845749" target="_blank"〉PubMed〈/a〉

    Description: The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source (in short: radio quasar) 3C 279, at a distance of more than 5 billion light-years (a redshift of 0.536). No quasar has been observed previously in very-high-energy gamma radiation, and this is also the most distant object detected emitting gamma rays above 50 gigaelectron volts. Because high-energy gamma rays may be stopped by interacting with the diffuse background light in the universe, the observations by MAGIC imply a low amount for such light, consistent with that known from galaxy counts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MAGIC Collaboration -- Albert, J -- Aliu, E -- Anderhub, H -- Antonelli, L A -- Antoranz, P -- Backes, M -- Baixeras, C -- Barrio, J A -- Bartko, H -- Bastieri, D -- Becker, J K -- Bednarek, W -- Berger, K -- Bernardini, E -- Bigongiari, C -- Biland, A -- Bock, R K -- Bonnoli, G -- Bordas, P -- Bosch-Ramon, V -- Bretz, T -- Britvitch, I -- Camara, M -- Carmona, E -- Chilingarian, A -- Commichau, S -- Contreras, J L -- Cortina, J -- Costado, M T -- Covino, S -- Curtef, V -- Dazzi, F -- De Angelis, A -- De Cea Del Pozo, E -- de Los Reyes, R -- De Lotto, B -- De Maria, M -- De Sabata, F -- Mendez, C Delgado -- Dominguez, A -- Dorner, D -- Doro, M -- Errando, M -- Fagiolini, M -- Ferenc, D -- Fernandez, E -- Firpo, R -- Fonseca, M V -- Font, L -- Galante, N -- Lopez, R J Garcia -- Garczarczyk, M -- Gaug, M -- Goebel, F -- Hayashida, M -- Herrero, A -- Hohne, D -- Hose, J -- Hsu, C C -- Huber, S -- Jogler, T -- Kneiske, T M -- Kranich, D -- La Barbera, A -- Laille, A -- Leonardo, E -- Lindfors, E -- Lombardi, S -- Longo, F -- Lopez, M -- Lorenz, E -- Majumdar, P -- Maneva, G -- Mankuzhiyil, N -- Mannheim, K -- Maraschi, L -- Mariotti, M -- Martinez, M -- Mazin, D -- Meucci, M -- Meyer, M -- Miranda, J M -- Mirzoyan, R -- Mizobuchi, S -- Moles, M -- Moralejo, A -- Nieto, D -- Nilsson, K -- Ninkovic, J -- Otte, N -- Oya, I -- Panniello, M -- Paoletti, R -- Paredes, J M -- Pasanen, M -- Pascoli, D -- Pauss, F -- Pegna, R G -- Perez-Torres, M A -- Persic, M -- Peruzzo, L -- Piccioli, A -- Prada, F -- Prandini, E -- Puchades, N -- Raymers, A -- Rhode, W -- Ribo, M -- Rico, J -- Rissi, M -- Robert, A -- Rugamer, S -- Saggion, A -- Saito, T Y -- Salvati, M -- Sanchez-Conde, M -- Sartori, P -- Satalecka, K -- Scalzotto, V -- Scapin, V -- Schmitt, R -- Schweizer, T -- Shayduk, M -- Shinozaki, K -- Shore, S N -- Sidro, N -- Sierpowska-Bartosik, A -- Sillanpaa, A -- Sobczynska, D -- Spanier, F -- Stamerra, A -- Stark, L S -- Takalo, L -- Tavecchio, F -- Temnikov, P -- Tescaro, D -- Teshima, M -- Tluczykont, M -- Torres, D F -- Turini, N -- Vankov, H -- Venturini, A -- Vitale, V -- Wagner, R M -- Wittek, W -- Zabalza, V -- Zandanel, F -- Zanin, R -- Zapatero, J -- New York, N.Y. -- Science. 2008 Jun 27;320(5884):1752-4. doi: 10.1126/science.1157087.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Universitat Wurzburg, D-97074 Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18583607" target="_blank"〉PubMed〈/a〉

    Description: One fundamental question about pulsars concerns the mechanism of their pulsed electromagnetic emission. Measuring the high-end region of a pulsar's spectrum would shed light on this question. By developing a new electronic trigger, we lowered the threshold of the Major Atmospheric gamma-ray Imaging Cherenkov (MAGIC) telescope to 25 giga-electron volts. In this configuration, we detected pulsed gamma-rays from the Crab pulsar that were greater than 25 giga-electron volts, revealing a relatively high cutoff energy in the phase-averaged spectrum. This indicates that the emission occurs far out in the magnetosphere, hence excluding the polar-cap scenario as a possible explanation of our measurement. The high cutoff energy also challenges the slot-gap scenario.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MAGIC Collaboration -- Aliu, E -- Anderhub, H -- Antonelli, L A -- Antoranz, P -- Backes, M -- Baixeras, C -- Barrio, J A -- Bartko, H -- Bastieri, D -- Becker, J K -- Bednarek, W -- Berger, K -- Bernardini, E -- Bigongiari, C -- Biland, A -- Bock, R K -- Bonnoli, G -- Bordas, P -- Bosch-Ramon, V -- Bretz, T -- Britvitch, I -- Camara, M -- Carmona, E -- Chilingarian, A -- Commichau, S -- Contreras, J L -- Cortina, J -- Costado, M T -- Covino, S -- Curtef, V -- Dazzi, F -- De Angelis, A -- De Cea Del Pozo, E -- de Los Reyes, R -- De Lotto, B -- De Maria, M -- De Sabata, F -- Delgado Mendez, C -- Dominguez, A -- Dorner, D -- Doro, M -- Elsasser, D -- Errando, M -- Fagiolini, M -- Ferenc, D -- Fernandez, E -- Firpo, R -- Fonseca, M V -- Font, L -- Galante, N -- Garcia Lopez, R J -- Garczarczyk, M -- Gaug, M -- Goebel, F -- Hadasch, D -- Hayashida, M -- Herrero, A -- Hohne, D -- Hose, J -- Hsu, C C -- Huber, S -- Jogler, T -- Kranich, D -- La Barbera, A -- Laille, A -- Leonardo, E -- Lindfors, E -- Lombardi, S -- Longo, F -- Lopez, M -- Lorenz, E -- Majumdar, P -- Maneva, G -- Mankuzhiyil, N -- Mannheim, K -- Maraschi, L -- Mariotti, M -- Martinez, M -- Mazin, D -- Meucci, M -- Meyer, M -- Miranda, J M -- Mirzoyan, R -- Moles, M -- Moralejo, A -- Nieto, D -- Nilsson, K -- Ninkovic, J -- Otte, N -- Oya, I -- Paoletti, R -- Paredes, J M -- Pasanen, M -- Pascoli, D -- Pauss, F -- Pegna, R G -- Perez-Torres, M A -- Persic, M -- Peruzzo, L -- Piccioli, A -- Prada, F -- Prandini, E -- Puchades, N -- Raymers, A -- Rhode, W -- Ribo, M -- Rico, J -- Rissi, M -- Robert, A -- Rugamer, S -- Saggion, A -- Saito, T Y -- Salvati, M -- Sanchez-Conde, M -- Sartori, P -- Satalecka, K -- Scalzotto, V -- Scapin, V -- Schweizer, T -- Shayduk, M -- Shinozaki, K -- Shore, S N -- Sidro, N -- Sierpowska-Bartosik, A -- Sillanpaa, A -- Sobczynska, D -- Spanier, F -- Stamerra, A -- Stark, L S -- Takalo, L -- Tavecchio, F -- Temnikov, P -- Tescaro, D -- Teshima, M -- Tluczykont, M -- Torres, D F -- Turini, N -- Vankov, H -- Venturini, A -- Vitale, V -- Wagner, R M -- Wittek, W -- Zabalza, V -- Zandanel, F -- Zanin, R -- Zapatero, J -- de Jager, O C -- de Ona Wilhelmi, E -- New York, N.Y. -- Science. 2008 Nov 21;322(5905):1221-4. doi: 10.1126/science.1164718.

    Description: MyD88 is a key downstream adapter for most Toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs). MyD88 deficiency in mice leads to susceptibility to a broad range of pathogens in experimental settings of infection. We describe a distinct situation in a natural setting of human infection. Nine children with autosomal recessive MyD88 deficiency suffered from life-threatening, often recurrent pyogenic bacterial infections, including invasive pneumococcal disease. However, these patients were otherwise healthy, with normal resistance to other microbes. Their clinical status improved with age, but not due to any cellular leakiness in MyD88 deficiency. The MyD88-dependent TLRs and IL-1Rs are therefore essential for protective immunity to a small number of pyogenic bacteria, but redundant for host defense to most natural infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2688396/" 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/PMC2688396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Bernuth, Horst -- Picard, Capucine -- Jin, Zhongbo -- Pankla, Rungnapa -- Xiao, Hui -- Ku, Cheng-Lung -- Chrabieh, Maya -- Mustapha, Imen Ben -- Ghandil, Pegah -- Camcioglu, Yildiz -- Vasconcelos, Julia -- Sirvent, Nicolas -- Guedes, Margarida -- Vitor, Artur Bonito -- Herrero-Mata, Maria Jose -- Arostegui, Juan Ignacio -- Rodrigo, Carlos -- Alsina, Laia -- Ruiz-Ortiz, Estibaliz -- Juan, Manel -- Fortuny, Claudia -- Yague, Jordi -- Anton, Jordi -- Pascal, Mariona -- Chang, Huey-Hsuan -- Janniere, Lucile -- Rose, Yoann -- Garty, Ben-Zion -- Chapel, Helen -- Issekutz, Andrew -- Marodi, Laszlo -- Rodriguez-Gallego, Carlos -- Banchereau, Jacques -- Abel, Laurent -- Li, Xiaoxia -- Chaussabel, Damien -- Puel, Anne -- Casanova, Jean-Laurent -- U19 AI057234/AI/NIAID NIH HHS/ -- U19 AI057234-02/AI/NIAID NIH HHS/ -- U19 AIO57234-02/PHS HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Aug 1;321(5889):691-6. doi: 10.1126/science.1158298.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genetics of Infectious Diseases, INSERM U550, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18669862" target="_blank"〉PubMed〈/a〉

    Description: The creation of enzymes capable of catalyzing any desired chemical reaction is a grand challenge for computational protein design. Using new algorithms that rely on hashing techniques to construct active sites for multistep reactions, we designed retro-aldolases that use four different catalytic motifs to catalyze the breaking of a carbon-carbon bond in a nonnatural substrate. Of the 72 designs that were experimentally characterized, 32, spanning a range of protein folds, had detectable retro-aldolase activity. Designs that used an explicit water molecule to mediate proton shuffling were significantly more successful, with rate accelerations of up to four orders of magnitude and multiple turnovers, than those involving charged side-chain networks. The atomic accuracy of the design process was confirmed by the x-ray crystal structure of active designs embedded in two protein scaffolds, both of which were nearly superimposable on the design model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3431203/" 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/PMC3431203/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Lin -- Althoff, Eric A -- Clemente, Fernando R -- Doyle, Lindsey -- Rothlisberger, Daniela -- Zanghellini, Alexandre -- Gallaher, Jasmine L -- Betker, Jamie L -- Tanaka, Fujie -- Barbas, Carlos F 3rd -- Hilvert, Donald -- Houk, Kendall N -- Stoddard, Barry L -- Baker, David -- R01 CA097328/CA/NCI NIH HHS/ -- R01 GM049857/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Mar 7;319(5868):1387-91. doi: 10.1126/science.1152692.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18323453" target="_blank"〉PubMed〈/a〉

    Description: Geochemical models for Mars predict carbonate formation during aqueous alteration. Carbonate-bearing rocks had not previously been detected on Mars' surface, but Mars Reconnaissance Orbiter mapping reveals a regional rock layer with near-infrared spectral characteristics that are consistent with the presence of magnesium carbonate in the Nili Fossae region. The carbonate is closely associated with both phyllosilicate-bearing and olivine-rich rock units and probably formed during the Noachian or early Hesperian era from the alteration of olivine by either hydrothermal fluids or near-surface water. The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ehlmann, Bethany L -- Mustard, John F -- Murchie, Scott L -- Poulet, Francois -- Bishop, Janice L -- Brown, Adrian J -- Calvin, Wendy M -- Clark, Roger N -- Marais, David J Des -- Milliken, Ralph E -- Roach, Leah H -- Roush, Ted L -- Swayze, Gregg A -- Wray, James J -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1828-32. doi: 10.1126/science.1164759.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geological Sciences, Brown University, Providence, RI02912, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19095939" target="_blank"〉PubMed〈/a〉

    Description: It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representing 3.5 million specimens, but only when older analytical protocols are used. Moreover, analyses that employ sampling standardization and more robust counting methods show a modest rise in diversity with no clear trend after the mid-Cretaceous. Globally, locally, and at both high and low latitudes, diversity was less than twice as high in the Neogene as in the mid-Paleozoic. The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alroy, John -- Aberhan, Martin -- Bottjer, David J -- Foote, Michael -- Fursich, Franz T -- Harries, Peter J -- Hendy, Austin J W -- Holland, Steven M -- Ivany, Linda C -- Kiessling, Wolfgang -- Kosnik, Matthew A -- Marshall, Charles R -- McGowan, Alistair J -- Miller, Arnold I -- Olszewski, Thomas D -- Patzkowsky, Mark E -- Peters, Shanan E -- Villier, Loic -- Wagner, Peter J -- Bonuso, Nicole -- Borkow, Philip S -- Brenneis, Benjamin -- Clapham, Matthew E -- Fall, Leigh M -- Ferguson, Chad A -- Hanson, Victoria L -- Krug, Andrew Z -- Layou, Karen M -- Leckey, Erin H -- Nurnberg, Sabine -- Powers, Catherine M -- Sessa, Jocelyn A -- Simpson, Carl -- Tomasovych, Adam -- Visaggi, Christy C -- New York, N.Y. -- Science. 2008 Jul 4;321(5885):97-100. doi: 10.1126/science.1156963.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, University of California-Santa Barbara, 735 State Street, Santa Barbara, CA 93101, USA. alroy@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18599780" target="_blank"〉PubMed〈/a〉

    Description: The canonical Wnt-beta-catenin signaling pathway is initiated by inducing phosphorylation of one of the Wnt receptors, low-density lipoprotein receptor-related protein 6 (LRP6), at threonine residue 1479 (Thr1479) and serine residue 1490 (Ser1490). By screening a human kinase small interfering RNA library, we identified phosphatidylinositol 4-kinase type II alpha and phosphatidylinositol-4-phosphate 5-kinase type I (PIP5KI) as required for Wnt3a-induced LRP6 phosphorylation at Ser1490 in mammalian cells and confirmed that these kinases are important for Wnt signaling in Xenopus embryos. Wnt3a stimulates the formation of phosphatidylinositol 4,5-bisphosphates [PtdIns (4,5)P2] through frizzled and dishevelled, the latter of which directly interacted with and activated PIP5KI. In turn, PtdIns (4,5)P2 regulated phosphorylation of LRP6 at Thr1479 and Ser1490. Therefore, our study reveals a signaling mechanism for Wnt to regulate LRP6 phosphorylation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2532521/" 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/PMC2532521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Weijun -- Choi, Sun-Cheol -- Wang, He -- Qin, Yuanbo -- Volpicelli-Daley, Laura -- Swan, Laura -- Lucast, Louise -- Khoo, Cynthia -- Zhang, Xiaowu -- Li, Lin -- Abrams, Charles S -- Sokol, Sergei Y -- Wu, Dianqing -- AR051476/AR/NIAMS NIH HHS/ -- CA132317/CA/NCI NIH HHS/ -- DA018343/DA/NIDA NIH HHS/ -- HL080706/HL/NHLBI NIH HHS/ -- NS36251/NS/NINDS NIH HHS/ -- P30 DA018343/DA/NIDA NIH HHS/ -- R01 AR051476/AR/NIAMS NIH HHS/ -- R01 AR051476-01A1/AR/NIAMS NIH HHS/ -- R01 AR051476-02/AR/NIAMS NIH HHS/ -- R01 AR051476-03/AR/NIAMS NIH HHS/ -- R01 CA132317/CA/NCI NIH HHS/ -- R01 CA132317-01A2/CA/NCI NIH HHS/ -- R01 CA139395/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1350-3. doi: 10.1126/science.1160741.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18772438" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. We hypothesize that individually rare structural variants contribute to the illness. Microdeletions and microduplications 〉100 kilobases were identified by microarray comparative genomic hybridization of genomic DNA from 150 individuals with schizophrenia and 268 ancestry-matched controls. All variants were validated by high-resolution platforms. Novel deletions and duplications of genes were present in 5% of controls versus 15% of cases and 20% of young-onset cases, both highly significant differences. The association was independently replicated in patients with childhood-onset schizophrenia as compared with their parents. Mutations in cases disrupted genes disproportionately from signaling networks controlling neurodevelopment, including neuregulin and glutamate pathways. These results suggest that multiple, individually rare mutations altering genes in neurodevelopmental pathways contribute to schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walsh, Tom -- McClellan, Jon M -- McCarthy, Shane E -- Addington, Anjene M -- Pierce, Sarah B -- Cooper, Greg M -- Nord, Alex S -- Kusenda, Mary -- Malhotra, Dheeraj -- Bhandari, Abhishek -- Stray, Sunday M -- Rippey, Caitlin F -- Roccanova, Patricia -- Makarov, Vlad -- Lakshmi, B -- Findling, Robert L -- Sikich, Linmarie -- Stromberg, Thomas -- Merriman, Barry -- Gogtay, Nitin -- Butler, Philip -- Eckstrand, Kristen -- Noory, Laila -- Gochman, Peter -- Long, Robert -- Chen, Zugen -- Davis, Sean -- Baker, Carl -- Eichler, Evan E -- Meltzer, Paul S -- Nelson, Stanley F -- Singleton, Andrew B -- Lee, Ming K -- Rapoport, Judith L -- King, Mary-Claire -- Sebat, Jonathan -- HD043569/HD/NICHD NIH HHS/ -- M01 RR000046/RR/NCRR NIH HHS/ -- MH061355/MH/NIMH NIH HHS/ -- MH061464/MH/NIMH NIH HHS/ -- MH061528/MH/NIMH NIH HHS/ -- NS052108/NS/NINDS NIH HHS/ -- R01 HD043569/HD/NICHD NIH HHS/ -- RR000046/RR/NCRR NIH HHS/ -- RR025014/RR/NCRR NIH HHS/ -- U01 MH061355/MH/NIMH NIH HHS/ -- U01 MH061464/MH/NIMH NIH HHS/ -- U01 MH061528/MH/NIMH NIH HHS/ -- U24 NS052108/NS/NINDS NIH HHS/ -- UL1 RR025014/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):539-43. doi: 10.1126/science.1155174.
