Pulse of the Planet


Syndicated radio producer Jim Metzner (multiple radio media major-award winner, plus multiple NSF, Grammy Foundation, and Fulbright grants) produces NanoEarth sponsored Pulse of the Planet radio shows. These Pulse of the Planet radio shows are about nanoenvironmental research and environmental nanoscience and engineering in general. These shows are nationally distributed on NPR radio and as a podcast on Stitcher and iTunes. The radio audience for weekday broadcasts of Pulse of the Planet is estimated to be 220,000 listeners, heard over about 264 stations nationwide, and on Armed Forces Radio. On Stitcher and iTunes outlets, several NanoEarth-sponsored shows have surpassed 100,000 downloads!
