Researchers on the OPERA experiment at the Gran Sasso laboratory in Italy have announced the first direct observation of a tau particle in a muon neutrino beam sent through the Earth from CERN, 730 kilometers away. This is a significant result, providing the final missing piece of a puzzle that has been challenging science since the 1960s, and giving tantalizing hints of new physics to come.
