A team of researchers in Canada have made a bold stride in the struggle to detect dark matter. The PICASSO collaboration has documented the discovery of a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids.
The PICASSO collaboration has a new paper out in New Journal of Physics. Of course the press release text is a bit easier to digest. Recommended.
(Lots of things going on now, so this corner of the blogosphere has been a bit quiet lately. I won't promise anything.)
