...took 15 years to get the right gene, to neutralize a virus that could carry it, and to prove - first in test tubes and then in live animals - that the procedure was safe enough for humans. Finally a young man named Robert Johnson got the first shot. A team of U.K. doctors announced earlier this month, that they put a needle through Johnson's eye, into his retina, to replace the faulty gene that had been blinding him for years...
...taken ingenuity. In patients like Robert Johnson, Ali delivers the functional gene using a virus that's been modified so it won't attack the eye or reproduce. The two trial subjects so far have not had severe immune responses to the new matter in their eyes - always a danger. Scientists are especially hopeful because the procedure worked so well in its animal trials. Scanning the eyes of dogs that underwent the procedure, researchers could see how the photoreceptor cells had changed. More important, the previously blind dogs could see well enough to navigate through a maze...
...Boatright and his colleagues are working on a technique that would let ophthalmologists fix genes that not just fail to express themselves, like Robert Johnson's, but that have mutated in a way that they express themselves abnormally, a trickier proposition because doctors need to add something and suppress something else at the same time. (Boatright and co. would inject short DNA strands that, where they bound with the patient's DNA at the point of the fault, would alert the body's existing repair mechanisms to the problem). The future looks bright indeed...

...April 27, the paper reported that four students, including two who were identified as Crimson editors, had been arrested after protesting a speech by FBI Director Robert S. Mueller at the Kennedy School’s Institute of Politics. In subsequent stories about the arrests—charges were dropped May 10—the paper clarified that one of the protesters last wrote for The Crimson in 2004 and the other was a former editorial columnist...
