New test finds neutrinos didn't beat light barrier

(Reuters) - New research suggests neutrinos that appeared to break a basic law of physics by travelling faster than the speed of light kept within the universal speed limit after all.
The latest measurement of the sub-atomic particles' time of flight from the CERN research centre in Geneva to Gran Sasso in central Italy contradicts an initial super-fast reading reported last September, which caused a scientific sensation.
