Tomorrow the Discovery Channel will show an Ardipithecus documentary. I’ve embedded a couple preview clips they’ve been sending around. I don’t have cable myself (the same way an alcoholic doesn’t keep cases of gin). So I’ll leave it to commenters to offer reviews tomorrow.

There’s obviously a striking parallel with the TV mania that recently surrounded another primate fossil, Darwinius. Personally, I don’t see anything amiss (a priori, at least), with a documentary coming out right after a journal paper gets published. What I don’t relish is when the publicity for a show distorts the news coverage of a fossil, as happened with Darwinius. So I’d be curious what people who watch the show think.

Check out this movie that uses Play Doh to explain the evolution of single-celled microbes to multicellular animals. It’s from Creature Cast, a very promising blog on biology from Casey Dunn of Brown University and his compadres.

Deep down, we are all cannibals. In tomorrow’s issue of the New York Times, I take a look at the science of autophagy: how our cells destroy themselves to live again. It turns out that this cellular cannibalism is crucial for our well-being in many ways. Scientists are now trying to improve our ability to destroy ourselves as a potential treatment for diseases like cancer and Huntington disease, and perhaps even to slow the process of aging itself. Check it out.

Congratulations to Elizabeth Blackburn, Carol Greider, and Jack Szostak, who just won the Nobel Prize in Physiology or Medicine this morning. They won for their discovery of telomeres, the caps on the ends of chromosomes that keep them from degrading and ward off aging. The Nobel site has posted some useful information about why this was such a profound discovery.
