Today I caught a lecture by Paul Ewald explaining how a few fairly low-tech solutions could lead to an upward spiral of public health by taking advantage of the rapid evolutionary capability of virulent micro-oganisms. I've covered some of this material before in my wife's intro to evolution text, but this lecture makes the material more broadly accessible.
Ways to "manage" the germs' virulence range from blocking waterborne transmission (cholera) to building vector-proof houses and hospitals (malaria) to reducing the potential for sexual transmission (AIDS) to designing vaccines that disfavor virulent variants (TB).Or, we could keep asking the Pope to keep the poor and suffering in his prayer journal.

I've been signed up to receive the TED talks for a while. I absolutely love that they offer the talks online.
I actually clapped and cheered along with the crowd when Carolyn Porco showed the first images from the surface of Titan.
If you've any other mp4 video sites worth knowing about, please let me know. Mostly I watch the TED talks and the CFR video podcast.
