I typically enjoy listening to Podcast while I am working in the lab. Some of the ones I generally listen too include the Naked Scientist, Nature, NOVA ScienceNOW, NPR: Science Friday, Science Talk, the Onion Radio News, and I just subscribed to USGS CoreFacts today (saw that on someone's blog, just can't remember whose it was, sorry!).
So, what Podcast do you listen to. Can you recommend anything?
