Several experiments: AMS, ATIC, CREAM, PAMELA, etc., equipped with state-of-the art detectors, have recently presented or are going to present new results on the composition of the charged cosmic radiation with a significant improvement in statistics and systematics respect to existing data. From the energy spectra of antiparticles to the chemical composition and energy spectra of nuclei, these measurements have opened a new era of precision studies in cosmic rays that challenge our current understanding of cosmic-ray sources and acceleration and propagation mechanisms in the Galaxy. In this talk we will review these experiments and present their most recent scientific results.
