CRESST uncovers hint of dark matter

Published in Physics World, 8 Sep 2011

Physicists are finally closing in on dark matter, the elusive substance thought to make up most of the matter in the universe. Either that, or they’re being misled by some unknown source of error.

That seemed to be the general idea, after the team behind the CRESST (or the Cryogenic Rare Event Search with Superconducting Thermometers) experiment in Italy announced on Tuesday that it had uncovered signals that could be interpreted as dark matter. These signals join possible traces of dark matter seen by two other direct-detection experiments in recent years, which suggests that evidence is mounting. The trouble is, physicists cannot agree whether the different signals match up or not. […]
