New Scientist: Although considerable doubt remains within the physics community over last month’s surprising result in which neutrinos from CERN reportedly arrived at the OPERA detector in Italy faster than the speed of light, the first paper from the OPERA experiment has been accepted for publication in Physical Review Letters. In addition, preliminary results from a comparable experiment called ICARUS (Imaging Cosmic And Rare Underground Signals) are out, and they do not confirm OPERA’s speedy neutrinos, reports New Scientist‘s Lisa Grossman.
An ultracold atomic gas can sync into a single quantum state. Researchers uncovered a speed limit for the process that has implications for quantum computing and the evolution of the early universe.
