Submission + - Neutrinos -- and once again, symmetry is restored!

perturbed1 writes: A Fermilab press release today announced that MiniBooNE's latest results rule out the simple neutrino oscillation interpretation of the LSND experiment. Neutrinos have a tiny amount of mass, required by their oscillations, as observed in solar, atmospheric and reactor neutrino experiments. Combining these results with the LSND experiment's results required the presence of a *fourth* but "sterile" neutrino, breaking the 3-fold symmetry of particle families in the standard model! Symmetry in the particle kingdom has once again been restored. Standard model lives on!
