SUMMARY: Scientists have gathered the first data from the Cryogenic Dark Matter Search, which is located 750 metres underground in an old iron mine in Soudan, Minnesota. They're looking for Weakly Interacting Massive Particles (WIMPS); particles that can pass right through the Earth almost unaffected, but which interact through gravity. The experiment isn't conclusive, but the scientists were able to put some boundaries on the mass and number of interactions the particles should make as they pass through the instrument's detectors. Over the next few years, they will increase the sensitivity of their equipment to resolve interactions by a factor of 20.
