The origin of cosmic-rays at different energies, from a few GeV to 100 EeV, is still unknown. Recent neutrino and cosmic-ray measurements provide new clues to the solution of this old puzzle. I will discuss these new clues, with emphasis on the implications of IceCube’s detection of astrophysical high energy neutrinos, the main open questions, and the prospects for progress with future high energy neutrino measurements. The most important step forward would be an
identification of the neutrino sources, which will allow one to identify the cosmic-ray accelerators, to resolve open questions related to the accelerator models, and to study neutrino properties. The most promising method for identifying the sources is by association of a neutrino with an electromagnetic signal accompanying a transient event responsible for its generation.
