I am going to discuss some of the latest developments in neutrino physics, focusing on three interconnected aspects of this rapidly evolving field: precision, new physics and collective effects. The first aspect is a direct consequence of the huge experimental development, which has lead to a change of paradigm in neutrino physics: the precision at the percent level on mass-mixing parameters is making systematical uncertainties a delicate problem to deal with, whereas statistics is in general no longer a problem. The second aspect consists in using neutrinos to look for beyond standard model physics. This can be done in several ways: by looking at deviations to the standard neutrino oscillation pattern, or to the effects of an enhanced production of neutrinos in astrophysical environments. Furthermore, the next generation neutrino experiments will be powerful machines, capable not only to increase our precision in oscillation measurements, but also to look for exotic particles that might not be related to neutrinos at all. Finally, collective effects are non linear phenomena that are expected in flavour evolution when neutrinos propagate in dense environments like supernovae, neutron mergers or the early universe. These effects are still under investigation and they are a fundamental ingredient for a correct interpretation of future neutrino signals from such dense environments.
