After five years of data taking in space, the PAMELA experiment has presented new results on the energy spectra of protons, helium nuclei, electrons and positrons that might change our current understanding of the mechanisms of production, acceleration and propagation of cosmic rays in the Galaxy. In addition, PAMELA measurements of cosmic antiproton and positron fluxes are setting strong...

One of the key observables to understand the origin and the sources of Galactic cosmic rays is their elemental composition. The abundance of elements is measured directly with detectors above the atmosphere on balloons and satellites. At energies exceeding 10^14 eV information on the composition is derived from the observation of extensive air showers. Results of recent measurements will be...

I will discuss the role of anisotropy as a tool to discriminate among different scenarios for the origin of Galactic cosmic rays. The main aim of the presentation is that of stressing the need for a unified picture of acceleration, propagation, chemical composition and anisotropy. I will summarize the different contributions to cosmic ray anisotropies and the problems with current...
