Put that together with last week’s Tufts bone-marrow discovery, and it’s even better.

It would be a wonderful thing if the public-policy debates and heartwrenching conversations about medical research would move from the same-old embryonic-stem-cell talk to the more promising research that is going on that doesn’t carry the same kind of moral concerns with it. Every new discovery/story should be a nudge toward real progress in that regard. And it would actually help people.
