Recommended: NOVA scienceNOW. It’s a video program about current topics in science. My wife and I just watched the July 9 broadcast about repairs to Hubble, early primates, brain cancer research and drug-resistant bacteria. It was a great. Neil deGrasse Tyson’s enthusiasm is infectious, and the animated gags were a hoot. NOVA scienceNOW airs on PBS, but they also have content online and several RSS feeds.
