Neutrino particle 'flips to all flavours'

Neutrinos are among the fundamental building blocks of matter. They swarm all about us. The Sun, for example, releases them in huge quantities when it fuses hydrogen to make helium - the raw nuclear process at its core. They are, however, very difficult to study because they interact so weakly with normal matter. Hence, their nickname - "ghost particles". Nonetheless, scientists have been able to discern three flavours - electron neutrinos, muon neutrinos, and tau neutrinos. Previous research has characterised two forms of oscillations. The T2K experiment has now seen hints for a third transformation - that of a muon neutrino turning into an electron neutrino.
