摘要

Lauren Gravitz reports, for our annual feature selecting 10 important emerging technologies, on a technique for rapidly isolating long pieces of DNA very inexpensively-a boon to the nascent field of personalized medicine ("$100 Genome," p. 41). "I thought I had some idea of how cool this technology is, but I had no idea how powerful until I saw it in action," says Gravitz. "Over the course of 15 minutes, they took a sample of commercial DNA, broke it up into long fragments, labeled it, loaded it into one of their chips, and placed the chip on a normal microscope with a camera attached. Suddenly, on the monitor attached to the camera, strands of DNA started flying through the chip, and I realized it was the first time I had ever actually seen molecules of DNA. They were no longer just images in a book." Gravitz also wrote this issue's Demo ("Laser Show in the Surgical Suite," p.88), on a laser technique that can prompt wounds to stitchrnthemselves closed. "It was pretty incredible to watch. With just a laser and a bit of dye, the skin appeared to be healing itself," she says. Gravitz is a freelance science writer whose work has appeared in Discover, the Christian Science Monitor, the Economist, and O, The Oprah Magazine, among other publications.
