The note in the Internal Medicine thread about podcasts made me think of some that I've been enjoying recently. The American Academy of Neurology does quite a good, short podcast featuring 1-2 articles from the week's issue of Neurology. Also the Lancet does a reasonably good neurology podcast.
I use Downcast on my iPad, which is excellent for me because it updates podcasts in the background. I don't have to sync with my computer all the time to get the latest editions. I find it superior to iTunes in every way.
