Neutrinos sent from CERN to Gran Sasso respect the cosmic speed limit, experiments confirm

The latest results on the time of flight of neutrinos from CERN to the INFN Gran Sasso Laboratory have just been presented. Four experiments -- Borexino, ICARUS, LVD and OPERA -- all measure a neutrino time of flight consistent with the speed of light. This is at odds with a measurement that the OPERA collaboration put up for scrutiny last September, indicating that the original OPERA measurement can be attributed to a faulty element of the experiment's fibre optic timing system.
