Deep underground, SuperCDMS begins hunting light dark matter with 24 cryogenic crystals

In the hunt for one of nature's most elusive substances-dark matter, which makes up 85% of all matter in the universe-scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB-one of the world's most sensitive dark matter searches-has begun collecting its first scientific data.
