Researchers at Caltech recently built the most powerful DNA-based computer ever made by humans.  That result is described in full in June 3rd’s issue of Science.

But, why read a stodgy paper when you can watch this 12-minute video that explains the whole thing using a fairy tale of a “magic book”?  It’s a bit technical, really, but what a great idea—every breakthrough paper should include a YouTube video like this that explains the results.
