Did You Know?We Have a Secret Underground Labratory in Sudbury, Ont. Canada is at the forefront in the international search for new forces and forms of matter thanks to SNOLAB. Designed for the study of neutrinoand dark matter physics, it’s the deepest clean laboratory in the world dedicated to this type of work. The lab, which was once the Sudbury NeutrinoObservatory, was built in a mine to avoid interference from environmental and solar radioactivity.
