This result is from a legitimate experimental group. It's much more likely to be experimental error than new physics, though: previous observations of neutrinos coincident with the light emitted by supernova 1987a (much, much farther away) indicate that neutrinos travel at light speed to 1 part in 10^8 [1,2]
