Cosmic-ray theory gets the cold shoulder
One of the leading theories describing how the most energetic cosmic rays are produced may need a rethink in light of a new study by physicists at the IceCube Neutrino Observatory in Antarctica. The team had set out to detect the extremely energetic neutrinos that are expected to be produced alongside high-energy cosmic rays in the violent explosions that mark the deaths of massive stars but after looking at hundreds of these explosions, no such neutrinos have been found.

I suppose they need to go back to basics, but how far back to basics- throw out Einstein maybe
