More on the “are neutrinos faster than light or not” debate.
A rival experiment to the original OPERA one that found the neutrinos going faster than light – which since has been found to be doubtful, see previous post – called ICARUS (these physicists do seem to like a good acronym) has recorded neutrinos travelling from CERN in Switzerland going as fast as light, but no faster.

Phew. That was a rather ungainly sentence. But we can all rest easy knowing that the special theory of relativity still holds. For now.
