I am starting to browse around at JoVE (the Journal of Visualized Experiments). This is an open journal dedicated to publishing biological research in a visual format. It is pretty cool. Some good videos include ones by Jared Ledbetter's group on studying microbes inside termites (see Layers of Symbiosis - Visualizing the Termite Hindgut Microbial Community
and Extracting DNA from the Gut Microbes of the Termite (Zootermopsis nevadensis)) for example. Others of interest to this blog include one by Ed Delong's group on Large-Scale Screens of Metagenomic Libraries.
Anyway - JoVE is definitely worth checking out ... visual presentations are probably the way of the future ...
In addition to experiments, JoVE also has some interviews. For example, I am embedding a nice video from JoVE with a talk by Ed Delong on microbial communities (Microbial communities in nature and laboratory - interview (Video Protocol). To view the embedded video click the play button below.
