Neutrinos could shed light on why the Universe has so much more matter than antimatter

A major finding in particle physics reminds us of the importance of robust preliminary results — and paves the way for more exciting discoveries.

Credit: Kamioka Observatory, ICRR, Univ. Tokyo Nuclear-weapons physicists Clyde Cowan and Frederick Reines considered the neutrino “the smallest bit of material reality ever conceived of by man” [sic]. That was in a commentary 1 for Nature in 1956, published a few months after they published a paper in Science 2 reporting the experimental discovery of neutrinos. These subatomic particles lack an ele
