Nova | Pbs

In light of the amazing mine rescue in Chile last week, our partners at PRI's "The World" asked whether technology could be used to prevent mining accidents in the first place. In this podcast, The World's Lisa Mullins interviews Mark Yim, a mechanical engineer at the University of Pennsylvania in Philadelphia. Interview produced by PRI's The World. NOVA is produced by WGBH in Boston. Funding for NOVA is provided by ExxonMobil, David H. Koch, the Howard Hughes Medical Institute, the Corporation for Public Broadcasting, and public television viewers. To learn more about the Chilean mine rescue, go to pbs.org/nova/tech
