Neutrino shape-shift points to new physics - most experiments measure the rate of neutrino oscillation by starting with one neutrino type and seeing how many of them disappear by the time the particles reach a detector, rather than seeing the transformed neutrino arrive anywhere...
They have detected a total of 28 electron neutrinos, when fewer than 5 would be expected if the neutrinos were not oscillating. Odds that the result is a fluke are less than one in a trillion...
Now that we have seen the muon neutrino morph into the electron neutrino in normal matter, physicists can run the T2K experiment with a beam of anti-muon neutrinos. Subtle differences in the way neutrinos and antineutrinos oscillate could have skewed the ratios of matter and antimatter production in the early universe...
