scivee.tv has many video clips of real scientists discussing their research. The goal of the site is to give a broad range of learners- from elementary to college level- access to cutting edge science. See a video HERE explaining the site.
I found a wonderful clip of female scientists discussing how and why they got into the sciences.
Applications for Science Teachers: This site seems most appropriate for high school and college teachers of science. I’m interested to see how this site evolves. I think the ideas of a postercast and a pubcast can really change the way ideas are shared in science.
