So, interestingly enough the leading theory for the identity of the bulk of dark matter is the "weekly interacting massive particle" (or WIMP) the neutralino, and there has been recent evidence from the Fermi gamma-ray telescope that supports the theory that the neutralino is the primary component of dark matter. http://arxiv.org/abs/1201.1003 http://arxiv.org/abs/1205.1045

The Higgs wasn't the only predicted particle that evidence has been found for recently. It looks like the Fermi gamma-ray telescope found some decent evidence that cosmological dark matter is composed of neutralinos, which have a rest mass, oddly, about half that of the Higgs: Evidence for gamma-ray halos around galaxy clusters: http://arxiv.org/abs/1201.1003 Evidence for a 130 GeV spike in gamma-ray emissions in certain locales: http://arxiv.org/abs/1205.1045
