    Description: Author(s): A. Rubenok, J. A. Slater, P. Chan, I. Lucio-Martinez, and W. Tittel Several vulnerabilities of single-photon detectors have recently been exploited to compromise the security of quantum-key-distribution (QKD) systems. In this Letter, we report the first proof-of-principle implementation of a new quantum-key-distribution protocol that is immune to any such attack. Mo... [Phys. Rev.

Rosenbusch Optically trapped ensembles are of crucial importance for frequency measurements and quantum memories but generally suffer from strong dephasing due to inhomogeneous density and light shifts. We demonstrate a drastic increase of the coherence time to 21 s on the magnetic field insensitive clock tran... [Phys. Rev. Lett. 106, 240801] Published Thu Jun 16, 2011

    Description: Author(s): Philipp Schindler, Thomas Monz, Daniel Nigg, Julio T. Barreiro, Esteban A. Martinez, Matthias F. Brandl, Michael Chwalla, Markus Hennrich, and Rainer Blatt In general, a quantum measurement yields an undetermined answer and alters the system to be consistent with the measurement result. This process maps multiple initial states into a single state and thus cannot be reversed. This has important implications in quantum information processing, where erro... [Phys. Rev.

    Description: The first chordates appear in the fossil record at the time of the Cambrian explosion, nearly 550 million years ago. The modern ascidian tadpole represents a plausible approximation to these ancestral chordates. To illuminate the origins of chordate and vertebrates, we generated a draft of the protein-coding portion of the genome of the most studied ascidian, Ciona intestinalis. The Ciona genome contains approximately 16,000 protein-coding genes, similar to the number in other invertebrates, but only half that found in vertebrates. Vertebrate gene families are typically found in simplified form in Ciona, suggesting that ascidians contain the basic ancestral complement of genes involved in cell signaling and development. The ascidian genome has also acquired a number of lineage-specific innovations, including a group of genes engaged in cellulose metabolism that are related to those in bacteria and fungi.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehal, Paramvir -- Satou, Yutaka -- Campbell, Robert K -- Chapman, Jarrod -- Degnan, Bernard -- De Tomaso, Anthony -- Davidson, Brad -- Di Gregorio, Anna -- Gelpke, Maarten -- Goodstein, David M -- Harafuji, Naoe -- Hastings, Kenneth E M -- Ho, Isaac -- Hotta, Kohji -- Huang, Wayne -- Kawashima, Takeshi -- Lemaire, Patrick -- Martinez, Diego -- Meinertzhagen, Ian A -- Necula, Simona -- Nonaka, Masaru -- Putnam, Nik -- Rash, Sam -- Saiga, Hidetoshi -- Satake, Masanobu -- Terry, Astrid -- Yamada, Lixy -- Wang, Hong-Gang -- Awazu, Satoko -- Azumi, Kaoru -- Boore, Jeffrey -- Branno, Margherita -- Chin-Bow, Stephen -- DeSantis, Rosaria -- Doyle, Sharon -- Francino, Pilar -- Keys, David N -- Haga, Shinobu -- Hayashi, Hiroko -- Hino, Kyosuke -- Imai, Kaoru S -- Inaba, Kazuo -- Kano, Shungo -- Kobayashi, Kenji -- Kobayashi, Mari -- Lee, Byung-In -- Makabe, Kazuhiro W -- Manohar, Chitra -- Matassi, Giorgio -- Medina, Monica -- Mochizuki, Yasuaki -- Mount, Steve -- Morishita, Tomomi -- Miura, Sachiko -- Nakayama, Akie -- Nishizaka, Satoko -- Nomoto, Hisayo -- Ohta, Fumiko -- Oishi, Kazuko -- Rigoutsos, Isidore -- Sano, Masako -- Sasaki, Akane -- Sasakura, Yasunori -- Shoguchi, Eiichi -- Shin-i, Tadasu -- Spagnuolo, Antoinetta -- Stainier, Didier -- Suzuki, Miho M -- Tassy, Olivier -- Takatori, Naohito -- Tokuoka, Miki -- Yagi, Kasumi -- Yoshizaki, Fumiko -- Wada, Shuichi -- Zhang, Cindy -- Hyatt, P Douglas -- Larimer, Frank -- Detter, Chris -- Doggett, Norman -- Glavina, Tijana -- Hawkins, Trevor -- Richardson, Paul -- Lucas, Susan -- Kohara, Yuji -- Levine, Michael -- Satoh, Nori -- Rokhsar, Daniel S -- HD-37105/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2002 Dec 13;298(5601):2157-67.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12481130" target="_blank"〉PubMed〈/a〉

    Description: Transcription factors (TFs) direct gene expression by binding to DNA regulatory regions. To explore the evolution of gene regulation, we used chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) to determine experimentally the genome-wide occupancy of two TFs, CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha, in the livers of five vertebrates. Although each TF displays highly conserved DNA binding preferences, most binding is species-specific, and aligned binding events present in all five species are rare. Regions near genes with expression levels that are dependent on a TF are often bound by the TF in multiple species yet show no enhanced DNA sequence constraint. Binding divergence between species can be largely explained by sequence changes to the bound motifs. Among the binding events lost in one lineage, only half are recovered by another binding event within 10 kilobases. Our results reveal large interspecies differences in transcriptional regulation and provide insight into regulatory evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" 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/PMC3008766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, Dominic -- Wilson, Michael D -- Ballester, Benoit -- Schwalie, Petra C -- Brown, Gordon D -- Marshall, Aileen -- Kutter, Claudia -- Watt, Stephen -- Martinez-Jimenez, Celia P -- Mackay, Sarah -- Talianidis, Iannis -- Flicek, Paul -- Odom, Duncan T -- 062023/Wellcome Trust/United Kingdom -- 079643/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- WT062023/Wellcome Trust/United Kingdom -- WT079643/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2010 May 21;328(5981):1036-40. doi: 10.1126/science.1186176.

    Description: It is predicted that climate change will cause species extinctions and distributional shifts in coming decades, but data to validate these predictions are relatively scarce. Here, we compare recent and historical surveys for 48 Mexican lizard species at 200 sites. Since 1975, 12% of local populations have gone extinct. We verified physiological models of extinction risk with observed local extinctions and extended projections worldwide. Since 1975, we estimate that 4% of local populations have gone extinct worldwide, but by 2080 local extinctions are projected to reach 39% worldwide, and species extinctions may reach 20%. Global extinction projections were validated with local extinctions observed from 1975 to 2009 for regional biotas on four other continents, suggesting that lizards have already crossed a threshold for extinctions caused by climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinervo, Barry -- Mendez-de-la-Cruz, Fausto -- Miles, Donald B -- Heulin, Benoit -- Bastiaans, Elizabeth -- Villagran-Santa Cruz, Maricela -- Lara-Resendiz, Rafael -- Martinez-Mendez, Norberto -- Calderon-Espinosa, Martha Lucia -- Meza-Lazaro, Rubi Nelsi -- Gadsden, Hector -- Avila, Luciano Javier -- Morando, Mariana -- De la Riva, Ignacio J -- Victoriano Sepulveda, Pedro -- Rocha, Carlos Frederico Duarte -- Ibarguengoytia, Nora -- Aguilar Puntriano, Cesar -- Massot, Manuel -- Lepetz, Virginie -- Oksanen, Tuula A -- Chapple, David G -- Bauer, Aaron M -- Branch, William R -- Clobert, Jean -- Sites, Jack W Jr -- New York, N.Y. -- Science. 2010 May 14;328(5980):894-9. doi: 10.1126/science.1184695.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95064, USA. lizardrps@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20466932" target="_blank"〉PubMed〈/a〉
