Old South Dakota gold mine to host giant neutrino experiment

Construction of the Deep Underground Neutrino Experiment (Dune) is due to start on Monday in the former Homestake gold mine in Lead, South Dakota. Engineers will assemble four huge detectors in caverns a mile underground to catch neutrinos from the Sun, supernovae and a beam fired through 1,300km of rock from a lab near Chicago, hoping to explain why matter dominates over antimatter.
