Le champ magnétique terrestre s'inverse au rythme de la tectonique des plaques - | @scoopit Discussions about Energy and Our Future suggested on @scoopit to Faster-than-light test runs again suggested on @scoopit to 28 October 2011Last updated at 08:51 By Paul Rincon Science editor, BBC News website The neutrinos are fired deep under the Italian Apennines to the Gran Sasso lab Scientists who announced that sub-atomic particles might be able to travel faster than light are to rerun their experiment in a different way. This will address criticisms and allow the physicists to shore up their analysis as much as possible before submitting it for publication. Dr Sergio Bertolucci said it was vital not to "fool around" given the staggering implications of the result. So they are doing all they can to rule out more pedestrian explanations. Physicists working on the Opera experiment announced the perplexing findings last month. Neutrinos sent through the ground from Cern (the home of the Large Hadron Collider) in Geneva toward the Gran Sasso laboratory 732km away in Italy seemed to show up a tiny fraction of a second earlier than light would have.

Astronomers discover complex organic matter in the universe | KurzweilAI suggested on @scoopit to A spectrum of complex organics from the European Space Agency's Infrared Space Observatory superimposed on an image of the Orion nebula, where these compounds are found (credit: NASA, C.R. O'Dell, S.K. Wong/Rice University) Organic compounds of unexpected complexity exist throughout the universe, Prof. The organic substance they found contains a mixture of aromatic (ring-like) and aliphatic (chain-like) components that are so complex, their chemical structures resemble those of coal and petroleum. Unidentified radiation from the universe The researchers investigated an unsolved phenomenon: a set of infrared emissions detected in stars, interstellar space, and galaxies, known as “Unidentified Infrared Emission features.” “Our work has shown that stars have no problem making complex organic compounds under near-vacuum conditions,” says Kwok. Most interestingly, this organic star dust is similar in structure to complex organic compounds found in meteorites.
