Yale University physicist Daniel McKinsey will host "Facing the Challenge of Dark Matter," at 4:30 p.m. Monday, Oct. 5, in Room 252 of the Electrical Engineering/Physics Building on the campus of the South Dakota School of Mines & Technology.

The lecture is free and suitable for high school science students, undergraduates, graduate students and anyone else interested in the fundamental scientific mysteries of the universe.

McKinsey will explain how the Large Underground Xenon detector at the Sanford Lab will search for a leading candidate for dark matter - the "weakly interacting massive particle."
