  • The first deep-space neutrinos to be detected since the 1980s may be the spawn of mystery dark matter. That would explain puzzling features of these particles--and suggest an unusual identity for dark matter. Pasquale Serpico of the University of Savoy in Annecy-le-Vieux, France, and colleagues calculated that dark matter particles of 1 PeV would decay either directly into neutrinos of around 1 PeV, or into other particles and then into neutrinos with energies of tens of TeV. It exactly reproduces the features that one could see in IceCube, says Serpico.
