Chinese detector edges closer to solving the mystery of neutrino mass

The gold-coloured photo tubes in China's neutrino detector are super efficient at collecting photons. Credit: Xinhua/Shutterstock The first of a new generation of neutrino experiments has begun to make its mark. With just two months of data, the Jiangmen Underground Neutrino Observatory (JUNO) experiment in Guangdong, China, has captured crucial details of how the mysterious particles can switch identities in flight 1 , with better precision than all previous experiments. …
