This shifts the debate fundamentally. Those who had moral reservations about research on the youngest of humans but were persuaded of the need to pursue treatments can now support this promising research without compromising their pro-life conviction. At the same time, those who claimed that embryonic research was the only promising way forward can unite around a promising new technique that presents no ethical dilemmas.
What the vast majority of Americans want is now possible: the pursuit of promising research that does not cross ethical lines, honors human dignity, and preserves innocent life.
As is so often the case with science news, the actual facts aren't quite so pat as the headlines make them out to be. We're still years away from putting these discoveries to any practical use. But it is a ray of hope, in what had been an increasingly ugly ethical war.
