  Recent results by space borne experiments took cosmic ray data to a precision
level. These new results are able to challenge the conventional scenario for
cosmic ray acceleration and propagation in the Milky Way. In these
contributions, written for the XVII Vulcano Workshop, we will give an overview
of the latest results of the cosmic ray fluxes, and some possible
interpretations will be discussed. These measurements have a common feature,
namely the presence of unexpected and still not yet fully understood spectral
features.
