Experiments such as the Cryogenic Dark Matter Search (CDMS) try to directly detect dark matter particles by searching for the rare interaction of such particles with those that make up normal matter, particularly with atomic nuclei.

Using detectors chilled to near absolute zero, from a vantage point half a mile below ground, physicists of the Cryogenic Dark Matter Search today (November 12) announced the launch of a quest that could lead to solving two mysteries that may turn out to be one and the same: the identity of the dark matter that pervades the universe, and the existence of supersymmetric particles predicted by particle physics theory.
