Ultra-precise test confirms photons are bosons

Physicists have carried out an extremely precise test of the one of the cornerstones of modern physics – the idea that the two types of fundamental particle, bosons and fermions, follow two distinct kinds of statistical behaviour. The laser-based experiment confirmed that photons behave according to Bose–Einstein statistics, narrowing the odds that photons could in fact be fermions by about a factor of 1000 compared with previous tests.
