Poröses Eis, wie es im Weltall überall zu finden ist, haben der Innsbrucker Chemiker Thomas Lörting und sein Team näher unter die Lupe genommen. In der Fachzeitschrift Physical Review Letters berichten die Forscher, wie sie das amorphe Eis beim Aufwärmen beobachtet haben. Die als mögliche Geburtsstätte des Lebens geltenden Eisstrukturen zeigen dabei ein überraschendes Verhalten. (more…)
Washington, DC — New work from Carnegie’s Peter Driscoll suggests Earth’s ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two. It is published in Geophysical Research Letters. (more…)
Hillary Clinton’s paid speeches – a ‘secret’? – not any more. But how much she was paid for each speech?
According to The Guardian – ‘her minimum fee was $225,000 per speech’ and her hosts make a long list of banks, securities firms and other financial institutions. (more…)
Freiburger Forscher zeigen, wie eine molekulare Fassstruktur unterschiedliche Funktionen in Mitochondrien ausübt
Freiburger Forscherinnen und Forscher haben entdeckt, dass das molekulare Fassprotein Mdm10 durch Anbindung an Proteinmaschinen unterschiedliche Funktionen für die Entstehung und Aufrechterhaltung der Struktur von Mitochondrien ausführen kann. Diese produzieren als Kraftwerke der Zellen beispielsweise die Energie für deren Stoffwechsel. Das Team um Prof. Dr. Nikolaus Pfanner und Privatdozent Dr. Thomas Becker vom Institut für Biochemie und Molekularbiologie der Universität Freiburg hat gemeinsam mit weiteren Kolleginnen und Kollegen die Ergebnisse in der Fachzeitschrift „Nature Communications“ veröffentlicht.
UCLA, Purdue computer scientists develop technique for combining massive sets of research data
As the field of “big data” has emerged as a tool for solving all sorts of scientific and societal questions, one of the main challenges that remains is whether, and how, multiple sets of data from various sources could be combined to determine cause-and-effect relationships in new and untested situations. Now, computer scientists from UCLA and Purdue University have devised a theoretical solution to that problem. (more…)
When Washington legalized recreational marijuana in 2012, a primary concern was how to ensure it was kept out of the reach of children. (more…)
Human Papillomavirus (HPV) drives a greater number of head and neck cancers than previously thought, finds new research from UCL and the University of Southampton. (more…)
The “a-ha!” moment came during one of her many modeling shoots, when Rian Buckley often wore clothes that were pinned, clipped and altered to fit her body shape. She saw repeatedly how the same clothes — jeans in particular — can look drastically different on two models with the same clothing size. And she spent a lot of time listening to e-commerce retailers complain of lost revenue from returned clothing, especially denim, that didn’t fit. (more…)
