Dark matter or background noise? Results intriguing but not conclusive
Science Centric: 2010 Feb 13
Physicists may have glimpsed a particle that is a leading candidate for mysterious dark matter but say conclusive evidence remains elusive.

A 9-year search from a unique observatory in an old iron mine 2,000 feet underground has yielded two possible detections of weakly interacting massive particles, or WIMPs. But physicists, who include two University of Florida researchers, say there is about a one in four chance that the detections were merely background noise - meaning that a worldwide hunt involving at least two dozen different observatories and hundreds of scientists will continue.
