Perhaps you've heard of some experiments involving neutrinos and the OPERA detector. It's possible that neutrinos may actually move faster than light. It's also possible they may not. Neutrinos have mass and light doesn't, so it would be very unexpected if neutrinos could travel faster than light. (Note: the reference is really the speed of light in a vacuum. We know charged particles can exceed the speed of light in a non-vacuum...that's what causes Cerenkov radiation).
Last year, research indicated that neutrinos might affect the rate of radioactive decay. But this was discounted.
