Beschreibung: Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and (18)O/(16)O in water and (13)C/(12)C, (18)O/(16)O, (17)O/(16)O, and (13)C(18)O/(12)C(16)O in carbon dioxide, made in the martian atmosphere at Gale Crater from the Curiosity rover using the Sample Analysis at Mars (SAM)'s tunable laser spectrometer (TLS). Comparison between our measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established ~4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Webster, Chris R -- Mahaffy, Paul R -- Flesch, Gregory J -- Niles,

Beschreibung: We report on results of an all-sky search for high-energy neutrino events interacting within the IceCube neutrino detector conducted between May 2010 and May 2012. The search follows up on the previous detection of two PeV neutrino events, with improved sensitivity and extended energy coverage down to about 30 TeV. Twenty-six additional events were observed, substantially more than expected from atmospheric backgrounds. Combined, both searches reject a purely atmospheric origin for the 28 events at the 4sigma level. These 28 events, which include the highest energy neutrinos ever observed, have flavors, directions, and energies inconsistent with those expected from the atmospheric muon and neutrino backgrounds. These properties are, however, consistent with generic predictions for an additional component of extraterrestrial origin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉IceCube Collaboration -- Aartsen, M G -- Abbasi, R -- Abdou, Y -- Ackermann, M -- Adams, J -- Aguilar, J A -- Ahlers, M -- Altmann, D -- Auffenberg, J -- Bai, X -- Baker, M -- Barwick, S W -- Baum, V -- Bay, R -- Beatty, J J -- Bechet, S -- Becker Tjus, J -- Becker, K-H -- Benabderrahmane, M L -- BenZvi, S -- Berghaus, P -- Berley, D -- Bernardini, E -- Bernhard, A -- Bertrand, D -- Besson, D Z -- Binder, G -- Bindig, D -- Bissok, M -- Blaufuss, E -- Blumenthal, J -- Boersma, D J -- Bohaichuk, S -- Bohm, C -- Bose, D -- Boser, S -- Botner, O -- Brayeur, L -- Bretz, H-P -- Brown, A M -- Bruijn, R -- Brunner, J -- Carson, M -- Casey, J -- Casier, M -- Chirkin, D -- Christov, A -- Christy, B -- Clark, K -- Clevermann, F -- Coenders, S -- Cohen, S -- Cowen, D F -- Cruz Silva, A H -- Danninger, M -- Daughhetee, J -- Davis, J C -- Day, M -- De Clercq, C -- De Ridder, S -- Desiati, P -- de Vries, K D -- de With, M -- DeYoung, T -- Diaz-Velez, J C -- Dunkman, M -- Eagan, R -- Eberhardt, B -- Eichmann, B -- Eisch, J -- Ellsworth, R W -- Euler, S -- Evenson, P A -- Fadiran, O -- Fazely, A R -- Fedynitch, A -- Feintzeig, J -- Feusels, T -- Filimonov, K -- Finley, C -- Fischer-Wasels, T -- Flis, S -- Franckowiak, A -- Frantzen, K -- Fuchs, T -- Gaisser, T K -- Gallagher, J -- Gerhardt, L -- Gladstone, L -- Glusenkamp, T -- Goldschmidt, A -- Golup, G -- Gonzalez, J G -- Goodman, J A -- Gora, D -- Grandmont, D T -- Grant, D -- Gross, A -- Ha, C -- Haj Ismail, A -- Hallen, P -- Hallgren, A -- Halzen, F -- Hanson, K -- Heereman, D -- Heinen, D -- Helbing, K -- Hellauer, R -- Hickford, S -- Hill, G C -- Hoffman, K D -- Hoffmann, R -- Homeier, A -- Hoshina, K -- Huelsnitz, W -- Hulth, P O -- Hultqvist, K -- Hussain, S -- Ishihara, A -- Jacobi, E -- Jacobsen, J -- Jagielski, K -- Japaridze, G S -- Jero, K -- Jlelati, O -- Kaminsky, B -- Kappes, A -- Karg, T -- Karle, A -- Kelley, J L -- Kiryluk, J -- Klas, J -- Klein, S R -- Kohne, J-H -- Kohnen, G -- Kolanoski, H -- Kopke, L -- Kopper, C -- Kopper, S -- Koskinen, D J -- Kowalski, M -- Krasberg, M -- Krings, K -- Kroll, G -- Kunnen, J -- Kurahashi, N -- Kuwabara, T -- Labare, M -- Landsman, H -- Larson, M J -- Lesiak-Bzdak, M -- Leuermann, M -- Leute, J -- Lunemann, J -- Madsen, J -- Maggi, G -- Maruyama, R -- Mase, K -- Matis, H S -- McNally, F -- Meagher, K -- Merck, M -- Meures, T -- Miarecki, S -- Middell, E -- Milke, N -- Miller, J -- Mohrmann, L -- Montaruli, T -- Morse, R -- Nahnhauer, R -- Naumann, U -- Niederhausen, H -- Nowicki, S C -- Nygren, D R -- Obertacke, A -- Odrowski, S -- Olivas, A -- O'Murchadha, A -- Paul, L -- Pepper, J A -- Perez de los Heros, C -- Pfendner, C -- Pieloth, D -- Pinat, E -- Posselt, J -- Price, P B -- Przybylski, G T -- Radel, L -- Rameez, M -- Rawlins, K -- Redl, P -- Reimann, R -- Resconi, E -- Rhode, W -- Ribordy, M -- Richman, M -- Riedel, B -- Rodrigues, J P -- Rott, C -- Ruhe, T -- Ruzybayev, B -- Ryckbosch, D -- Saba, S M -- Salameh, T -- Sander, H-G -- Santander, M -- Sarkar, S -- Schatto, K -- Scheriau, F -- Schmidt, T -- Schmitz, M -- Schoenen, S -- Schoneberg, S -- Schonwald, A -- Schukraft, A -- Schulte, L -- Schulz, O -- Seckel, D -- Sestayo, Y -- Seunarine, S -- Shanidze, R -- Sheremata, C -- Smith, M W E -- Soldin, D -- Spiczak, G M -- Spiering, C -- Stamatikos, M -- Stanev, T -- Stasik, A -- Stezelberger, T -- Stokstad, R G -- Stossl, A -- Strahler, E A -- Strom, R -- Sullivan, G W -- Taavola, H -- Taboada, I -- Tamburro, A -- Tepe, A -- Ter-Antonyan, S -- Tesic, G -- Tilav, S -- Toale, P A -- Toscano, S -- Unger, E -- Usner, M -- van Eijndhoven, N -- Van Overloop, A -- van Santen, J -- Vehring, M -- Voge, M -- Vraeghe, M -- Walck, C -- Waldenmaier, T -- Wallraff, M -- Weaver, Ch -- Wellons, M -- Wendt, C -- Westerhoff, S -- Whitehorn, N -- Wiebe, K -- Wiebusch, C H -- Williams, D R -- Wissing, H -- Wolf, M -- Wood, T R -- Woschnagg, K -- Xu, D L -- Xu, X W -- Yanez, J P -- Yodh, G -- Yoshida, S -- Zarzhitsky, P -- Ziemann, J -- Zierke, S -- Zoll, M -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):1242856. doi: 10.1126/science.1242856.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24264993" target="_blank"〉PubMed〈/a〉
