TL;DR: It is found that the positron fraction increases sharply over much of that range, in a way that appears to be completely inconsistent with secondary sources, and is concluded that a primary source, be it an astrophysical object or dark matter annihilation, is necessary.

TL;DR: PAMELA data challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy and find that the spectral shapes of these two species are different and cannot be described well by a single power law.

TL;DR: A new measurement of the cosmic-ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented, which is a tenfold improvement in statistics with respect to all previously published data.

TL;DR: The satellite-borne experiment PAMELA has been used to make a new measurement of the cosmic-ray antiproton flux and the antipropton-to-proton flux ratio which extends previously published measurements down to 60 MeV and up to 180 GeV in kinetic energy.

TL;DR: The PAMELA experiment is a satellite-borne apparatus designed to study charged particles in the cosmic radiation with a particular focus on antiparticles as discussed by the authors, which is mounted on the Resurs DK1 satellite that was launched from the Baikonur cosmodrome on June 15th 2006.
