GOSFORD: Physicists have detected signals that could be interpreted as dark matter, the elusive substance believed to comprise 80% of matter in the Universe, and say it could have a lower mass than suspected.

Researchers working on the Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) experiment in Italy, have announced they have detected weakly interacting particles that may be evidence for the elusive substance, only known because of the gravitational pull it exerts on ‘normal’ (baryonic) matter.
