Do-It-Yourself Genetic Engineering

By JON MOOALLEM, New York Times

IT ALL STARTED with a brawny, tattooed building contractor with a passion for exotic animals. He was taking biology classes at City College of San Francisco, a two-year community college, and when students started meeting informally early last year to think up a project for a coming science competition, he told them that he thought it would be cool if they re-engineered cells from electric eels into a source of alternative energy. Eventually the students scaled down that idea into something more feasible, though you would be forgiven if it still sounded like science fiction to you: they would build an electrical battery powered by bacteria. This also entailed building the bacteria itself — redesigning a living organism, using the tools of a radical new realm of genetic engineering called synthetic biology. more...
