The PBS program NOVA has produced an innovative, educational science program called scienceNow, which started airing this spring. I think the series is absolutely fantastic, not only because of the content, but because the host Robert Krulwich is able to convey the complex topics through his antics as well as serious discussion.

What's best about the actual shows is that they are available for viewing on the internet, so if you weren't able to watch it or record it on your Tivo, no problem. Just go to the site and watch the streaming video there!

Each show covers about 3 or 4 topics, and the most recent edition had a great section about stem cell research and therapeutic cloning.
