    Shakespeare's Sonnets, Encoded In DNA

    Reporting in Nature, researchers write of encoding a variety of files--jpg, mp3, txt and pdf--in strands of DNA. Lead author Nick Goldman says DNA is extraordinarily long-lasting, compared to today's hard drives and magnetic tapes. And if all the world's information were written in DNA, he says, it would fit in the back of a station wagon.
