DAMA , a research group that investigates rare processes in an underground laboratory of the Gran Sasso, has published results of an experiment that investigates dark matter. You can find out more about their work here:
The DAMA Project – Investigations on particle DArk MAtter and other rare processes with highly radiopure scintillators @ Gran Sasso
It is an interesting project using a well-known approach, looking for seasonal variations in data. They add an interesting twist by assuming that their dark matter target of sodium with it’s odd number of protons is the reason that their detector has succeeded in detecting dark matter while others have not.
I’m still skeptical that they have actually detected dark matter since there are other plausible explanations for the results. In any event, it is a fascinating development.
