Description: The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day, 560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with current propulsion systems and comparable shielding is found to be 0.66 +/- 0.12 sievert.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zeitlin, C -- Hassler, D M -- Cucinotta, F A -- Ehresmann, B -- Wimmer-Schweingruber, R F -- Brinza, D E -- Kang, S -- Weigle, G -- Bottcher, S -- Bohm, E -- Burmeister, S -- Guo, J -- Kohler, J -- Martin, C -- Posner, A -- Rafkin, S -- Reitz, G -- New York, N.Y. -- Science. 2013 May 31;340(6136):1080-4. doi: 10.1126/science.1235989.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Southwest Research Institute, Boulder, CO, USA. zeitlin@boulder.swri.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23723233" target="_blank"〉PubMed〈/a〉

Description: Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmann, Michael -- Hilton-Taylor, Craig -- Angulo, Ariadne -- Bohm, Monika -- Brooks, Thomas M -- Butchart, Stuart H M -- Carpenter, Kent E -- Chanson, Janice -- Collen, Ben -- Cox, Neil A -- Darwall, William R T -- Dulvy, Nicholas K -- Harrison, Lucy R -- Katariya, Vineet -- Pollock, Caroline M -- Quader, Suhel -- Richman, Nadia I -- Rodrigues, Ana S L -- Tognelli, Marcelo F -- Vie, Jean-Christophe -- Aguiar, John M -- Allen, David J -- Allen, Gerald R -- Amori, Giovanni -- Ananjeva, Natalia B -- Andreone, Franco -- Andrew, Paul -- Aquino Ortiz, Aida Luz -- Baillie, Jonathan E M -- Baldi, Ricardo -- Bell, Ben D -- Biju, S D -- Bird, Jeremy P -- Black-Decima, Patricia -- Blanc, J Julian -- Bolanos, Federico -- Bolivar-G, Wilmar -- Burfield, Ian J -- Burton, James A -- Capper, David R -- Castro, Fernando -- Catullo, Gianluca -- Cavanagh, Rachel D -- Channing, Alan -- Chao, Ning Labbish -- Chenery, Anna M -- Chiozza, Federica -- Clausnitzer, Viola -- Collar, Nigel J -- Collett, Leah C -- Collette, Bruce B -- Cortez Fernandez, Claudia F -- Craig, Matthew T -- Crosby, Michael J -- Cumberlidge, Neil -- Cuttelod, Annabelle -- Derocher, Andrew E -- Diesmos, Arvin C -- Donaldson, John S -- Duckworth, J W -- Dutson, Guy -- Dutta, S K -- Emslie, Richard H -- Farjon, Aljos -- Fowler, Sarah -- Freyhof, Jorg -- Garshelis, David L -- Gerlach, Justin -- Gower, David J -- Grant, Tandora D -- Hammerson, Geoffrey A -- Harris, Richard B -- Heaney, Lawrence R -- Hedges, S Blair -- Hero, Jean-Marc -- Hughes, Baz -- Hussain, Syed Ainul -- Icochea M, Javier -- Inger, Robert F -- Ishii, Nobuo -- Iskandar, Djoko T -- Jenkins, Richard K B -- Kaneko, Yoshio -- Kottelat, Maurice -- Kovacs, Kit M -- Kuzmin, Sergius L -- La Marca, Enrique -- Lamoreux, John F -- Lau, Michael W N -- Lavilla, Esteban O -- Leus, Kristin -- Lewison, Rebecca L -- Lichtenstein, Gabriela -- Livingstone, Suzanne R -- Lukoschek, Vimoksalehi -- Mallon, David P -- McGowan, Philip J K -- McIvor, Anna -- Moehlman, Patricia D -- Molur, Sanjay -- Munoz Alonso, Antonio -- Musick, John A -- Nowell, Kristin -- Nussbaum, Ronald A -- Olech, Wanda -- Orlov, Nikolay L -- Papenfuss, Theodore J -- Parra-Olea, Gabriela -- Perrin, William F -- Polidoro, Beth A -- Pourkazemi, Mohammad -- Racey, Paul A -- Ragle, James S -- Ram, Mala -- Rathbun, Galen -- Reynolds, Robert P -- Rhodin, Anders G J -- Richards, Stephen J -- Rodriguez, Lily O -- Ron, Santiago R -- Rondinini, Carlo -- Rylands, Anthony B -- Sadovy de Mitcheson, Yvonne -- Sanciangco, Jonnell C -- Sanders, Kate L -- Santos-Barrera, Georgina -- Schipper, Jan -- Self-Sullivan, Caryn -- Shi, Yichuan -- Shoemaker, Alan -- Short, Frederick T -- Sillero-Zubiri, Claudio -- Silvano, Debora L -- Smith, Kevin G -- Smith, Andrew T -- Snoeks, Jos -- Stattersfield, Alison J -- Symes, Andrew J -- Taber, Andrew B -- Talukdar, Bibhab K -- Temple, Helen J -- Timmins, Rob -- Tobias, Joseph A -- Tsytsulina, Katerina -- Tweddle, Denis -- Ubeda, Carmen -- Valenti, Sarah V -- van Dijk, Peter Paul -- Veiga, Liza M -- Veloso, Alberto -- Wege, David C -- Wilkinson, Mark -- Williamson, Elizabeth A -- Xie, Feng -- Young, Bruce E -- Akcakaya, H Resit -- Bennun, Leon -- Blackburn, Tim M -- Boitani, Luigi -- Dublin, Holly T -- da Fonseca, Gustavo A B -- Gascon, Claude -- Lacher, Thomas E Jr -- Mace, Georgina M -- Mainka, Susan A -- McNeely, Jeffery A -- Mittermeier, Russell A -- Reid, Gordon McGregor -- Rodriguez, Jon Paul -- Rosenberg, Andrew A -- Samways, Michael J -- Smart, Jane -- Stein, Bruce A -- Stuart, Simon N -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1503-9. doi: 10.1126/science.1194442.
