Science Media Library - Great for presentations
I stumbled upon the Science Online Media Library of the Howard Hughes Medical Institute. A nice collection of Videos, Lectures, Animations and textbook information on several topics and fields of the Biosciences. They even put up the lecture transcripts as pdf files. So if you are again struggling to find some fancy media for your next presentation or lecture you might wanna have a look. And if you just want to have some background information on one of the fields you will also find it quite helpful. Might save you a lot of time!
