Physicists are taking their attempt to unmask the secret identity of dark matter into a Canadian mine more than a mile underground. They are deploying a 4-kilogram bubble chamber at SNOLab, which is part of the Sudbury Neutrino Observatory in Ontario, Canada. A second 60-kilogram chamber will follow later this year.
