Experiment detects particles of dark matter, maybe
Events in underground experiment too few for certainty, but match the signature of WIMPs

Analyzing results of an experiment in a northern Minnesota mine, physicists report the possible detection of particles of dark matter — the proposed invisible material believed to account for about 80 percent of the mass of the universe. The physicists caution, however, that there’s about a one in four chance that ordinary subatomic particles, rather than dark matter, could account for the signals.
The experiment, called the Cryogenic Dark Matter Search, relies on 30 detectors made of germ...
