A Nice Little Science Podcast

And fairly new too, it's Short Wave over at NPR.  Ten minute (-ish) episodes, ready for the downloads.  From the blurb:

New discoveries, everyday mysteries, and the science behind the headlines – all in about 10 minutes, every weekday.  It's science for everyone, using a lot of creativity and a little humor.

Somehow and ironically, they have yet to do an episode on shortwave!  Maybe that'll be rectified in the new year.  Anyway, worth a listen.
