Spectral features in galactic cosmic rays

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