The IceCube neutrino telescope reports its most extensive search for neutrinos produced by dark matter annihilations in the Sun.

Three major drawbacks to the ΛCDM dark matter model of the universe may be ameliorated if a proposed particle couples to dark matter and to neutrinos.

A new analysis shows that it is possible to look for dark-matter particles with mass far below 1 giga-electron-volt by using atomic ionization.

New data from the PAMELA satellite on the abundance of antiprotons in cosmic rays still leave the door open for dark matter theories, as well as other explanations.

Theories of dark matter interacting with a light force carrier, proposed to explain the excess of high-energy positrons in the cosmic rays, turn out to have problems.

New data are inconsistent with previous measurements that showed an unexpected excess of diffuse gamma-ray emission in the Galaxy.

Detectors buried beneath the Antarctic ice place stringent limits on the presence of dark matter particles, called neutralinos, in the sun.
