Physicists have confirmed that neutrinos, which are thought to have
played a key role during the creation of the Universe, have mass.
This is the first major finding of the US-based Main Injector
Neutrino Oscillation Search (Minos) experiment.
The findings suggest that the Standard Model, which describes how the
building blocks of the Universe behave and interact, needs a revision.
Neutrinos are believed to be vital to our understanding of the Universe.
The findings build on work carried out by Japanese physicists.
