Biologists aren't the only ones who are extracting DNA. On her blog, Hsien-Hsien Lei posted a video from metacafe on how to do at-home DNA extractions. Using salt, water, and rubbing alcohol dangerously close to his computer keyboard, the star of the video ends up with stringy white clumps that look kind of like DNA. We're left waiting, though, for a video on how to do sequencing at home.
