NOVA Minute: Mark Lehner

In this podcast, hear a taste of what we're airing on WGBH 89.7 FM in Boston. We call audio tidbits like these "NOVA Minutes", and air them three time per week during Morning Edition. Since they're not yet available online, we'll sprinkle them liberally into the podcast feed over the next few months. Stay tuned! Produced by David Levin. 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.
