DNA Unzipped, On Tape, Explicit

Logic Bomb writes: "From the San Francisco Chronicle's story: 'Molecular action film highlights potential of nanotechnology.... Close to four years in the making, the grainy black-and-white movie stars an enzyme called helicase, chugging along brightly lit tracks of fluorescent-dyed microbial DNA.' Wow. The movie is actually sort of anti-climactic, but you can see clearly a brightly-fluorescing molecule moving along a string of smaller ones. It's quite something." I don't see a link to this movie, but the story is pretty captivating even so.
