Researchers at the University of Pennsylvania announced in April 2008 the use of an innovative gene therapy treatment to safely restore vision in three adults with a rare form of congenital blindness. The technique involves an injection that delivers DNA to the nucleus of a cell so it can begin making the protein that the blind patients don't have. Although the patients have not achieved normal eyesight, the results set the stage for possible treatment of other retinal diseases.

I am one of the most avid sports fans you'll find," Se-Jin Lee says. It's true. He'll watch anything. Basketball. Football. Fútbol. Billiards on channel seven-hundred-whatever. As a graduate student in the '80s Lee used to sit in his car in the driveway with the radio on to listen to the games of faraway baseball teams. Even now, in his lab at Johns Hopkins Medical School in Baltimore, he easily rattles off the NCAA basketball tournament winners in order from 1964 to 2007. And, like anyone who values fair competition these days, he's disturbed by the issue of performance-enhancing drugs in sports.
