That may soon change, if the beta cells Melton created can give scientists a full picture of the disease. If, for example, it turns out that the new beta cells can be made to survive the attack by the immune system, then the next step would be to return the functional beta cells, generated through strategies like the one used by Melton, back into the patients from whom the original skin cells came. But even that won't happen until more testing is done on the cells to ensure they are both safe and effective...
...cells become more established, says Dr. Rohit Kulkarni, a diabetes expert at Joslin Diabetes Center in Boston, the strategy could be expanded to help patients with either Type 1 or 2 diabetes. "It might even be more relevant for other types of diabetes where there is no immune-system attack," he says. In those cases, simply replacing nonfunctioning beta cells might go a long way toward treating or even curing the disease. (See how to prevent illness...

It’s the specifics, rather than the supremacy of the drone approach itself, that have come under attack. Pakistanis decry U.S. counterterrorist strikes in their country as a “violation of sovereignty” (apparently, contracting out assassination missions to third parties isn’t their preferred method), but these protests really boil down to wanting the missiles in their own hands.

"For several years, the public debate and discussion was about funding priorities and technology," says Ridge, "and I don't hear much of that. It just concerns me because there is still a lot of need...
...particular, he wonders why, eight years after 9/11, there is still no first-responder communications system so that police and fire departments across the country can communicate in the event of an attack. And he worries about the continued lack of tracking ability for foreign nationals who overstay their visas. "We don't know today if everybody who came in lawfully with a visa in the last five years has gone home," he says. "What happened to that sense of urgency...
