Scientists work toward storing digital information in DNA

Her computer, Karin Strauss says, contains her "digital attic"—a place where she stores that published math paper she wrote in high school, and computer science schoolwork from college. She'd like to preserve the stuff "as long as I live, at least," says Strauss, 37. But computers must be replaced every few years, and each time she must copy the information over, "which is a little bit of a headache." It would be much better, she says, if she could store it in DNA—the stuff our genes are made of. Strauss, who works at Microsoft Research in Redmond, Washington, is working to make that sci-fi fantasy a reality.
