Rumours that first dark matter particle found

Dark matter found? - www.newscientist.com
The physics blogs are abuzz with rumours that a particle of dark matter has finally been found.
If it is true, it is huge news. Dark matter is thought to make up 90 per cent of the universe's mass and what evidence there is for it remains highly controversial. That's why any news of a sighting is seized upon.
The Cryogenic Dark Matter Search experiment is one of several designed to look for the tell-tale signature of dark matter particles passing through. No one is sure what a dark matter particle will look like, though theory gives some pointers.
Most of the experiments have been designed to look for elusive massive particles called WIMPS that barely register as they pass through matter, because the only forces they experience are gravity and the weak nuclear force.

The gossip mill went into overdrive after a rumour leaked out that the CDMS collaboration has had a paper accepted by the journal Nature. Word is that the paper will appear in the 18 December issue.
We'll have to wait and see if the rumours turn out to be true. Even if not, with NASA's Fermi satellite looking for dark matter in space and the Large Hadron Collider up and running, 2010 could be the year we finally crack the dark matter mystery.
