Sophomore Holly Josephs asks, “What if running were the norm instead of walking?” in a radio story about sophomore Wesley Lau, who says running is the “most convenient” form of transportation. “A Runner’s Highs and Lows,” Josephs’ 2.5-minute piece created for MIT’s Terrascope Radio, was named to Generation PRX’s (Public Radio Exchange) list of Best Youth-Made Radio of 2013. In the interview, Lau says he plans to run every line of Boston’s subway in its entirety, including the Red Line’s 25-mile branch to Braintree. CEE lecturer Ari Epstein directs Terrascope Radio, which is part of MIT’s Terrascope program for freshmen, a collaboration of CEE and the Department of Earth, Atmospheric and Planetary Sciences.
