This is big news. Hoping it's true and gives us a clue about whether supersymmetry, string theory and related theories are correct. If it has some properties that only string theory could predict that would be a major bonus.
Still:
When the CDMS-II team looked at the analysis of their latest run – after accounting for all possible background particles and any faulty detectors in their stacks – they were in for a surprise. Their statistical models predicted that they would see 0.8 events during a run between 2007 and 2008, but instead they saw two.
The team is not claiming discovery of dark matter, because the result is not statistically significant. There is a 1-in-4 chance that it is merely due to fluctuations in the background noise. Had the experiment seen five events above the expected background, the claim for having detected dark matter would have been a lot stronger.
