CERN’s latest press release confirms the suspicions from last year’s result: neutrinos travel slower than light, and last year’s results were a result of a systematic error which has since been found and corrected.

Let me make sure I have this right: since neutrinos have mass (albeit, a very, very small amount), they don’t actually move at the speed of light; rather, they just have a speed that’s so close to lightspeed that it’s effectively the same.
Neutrinos. Now with Lite Speed!TM
So close to light speed we dare you to spot the difference.
Precisely. The difference between neutrino speed and lightspeed cannot be accurately measured when they travel Earth-sized distances with today’s equipment. To measure the speed of a neutrino, we need to either make more sensitive equipment or set up neutrino sources on one planet and detectors on another.
