Announcing the first results from Daya Bay: Discovery of a new kind of neutrino transformation

The Daya Bay Reactor Neutrino Experiment collaboration has announced a precise measurement of the last of the unsolved neutrino "mixing angles," which determine how neutrinos oscillate among different types. The ground-breaking collaboration, led by the United States and China, is the most sensitive reactor neutrino experiment in the world. The results promise new insight into why enough ordinary matter survived after the big bang to form everything visible in the universe. Read more
