  The Alpha Magnetic Spectrometer (AMS-02) is a particle physics experiment
designed to study origin and nature of Galactic Cosmic Rays (CRs) up to TeV
energies from space. With its high sensitivity, long exposure and excellent
identification capabilities, AMS is conducting a unique mission of fundamental
physics research in space. To date, more than 60 billion CR events have been
collected by AMS. The new results on CR leptons and the analysis and
light-nuclei are presented and discussed. The new leptonic data indicate the
existence of new sources of high-energy CR leptons, that may arise either by
dark-matter particles annihilation or by nearby astrophysical sources of
$e^{\pm}$ pairs. Future data at higher energies and forthcoming measurements on
the antiproton spectrum and the boron-to-carbon ratio will be crucial in
providing the discrimination among the different scenario.
