Since 1993, the Institut Jean Nicod has awarded the annual Jean Nicod Prize to a leading philosopher or cognitive scientist for his or her work in the interdisciplinary study of the mind. The recipient is expected to deliver a series of lectures. The lecture series of this past year's winner, philosopher Stephen Stich, is entitled "Moral Theory Meets Cognitive Science: How Cognitive Science Can Transform Traditional Debates", and is now available online in video form. Also available is the lecture series of the previous year's winner, evolutionary anthropologist Michael Tomasello: "Origins of Human Communication".

SciVee is a site where scientists can upload video presentations alongside their published research. I especially like this one, but there's a lot to explore.

Science Live site I found this because of the live coverage of the Festival of Science 2006 from Norwich, but found lots of other great links! Great for kids, but good for anyone curious about science. "What if you could watch any popular science lecture you wanted to? What if you could participate in any popular science event? What if you could find out what scientists themselves have to say about the issues that are important in society today? ScienceLive is an initiative that seeks to bring some of the best popular science events (discussions, lectures, interviews) directly to your home, so that you can watch these events whenever and from whereever you can.

Manakins (Manacus sp.) are small, colorful sparrow-sized birds found all over Central and South America. Manakin males engage in elaborate courtship dances, including rhythmic sounds they produce with their wings. No one really knew how the birds made this sounds, until Kimberly Bostwick, Curator of Birds and Mammals at the Cornell University Museum of Vertebrates, went into the jungles of Ecuador to film the birds at 1000 frames per second. As it turns out, different species of manakin use entirely different motion to produce the sounds. The Journal of Experimental Biology has published the results, complete with videos. Mark Barres, who studies avian genetic population structures at the Univ. of Wisconsin, has also filmed the mating dance of the Manakins [.mov].

The Meaning of Life according to various rather famous people (Dennett, Fukuyama, etc). I'm watching the Dennett video at the moment and it starts rather weakly, but, by midway through, is rolling along nicely. With topics like "being good without god" and "the anthropic principle" it struck me as relevant to a couple of recent askmefi threads.
Dennett: [pause] i guess i'll say it again, more slowly...
(oh, and the player interface is rather delicate - give it time to load and click play a few times...)
