Stem cell breakthrough promises to overcome ethical objections. I don't know, this is going to be all over the news, well, it already is. I don't think Ramesh Ponnuru or Kathryn Lopez are going to shut up about it for a long time. I am cautiously optimistic, but unfortunately this will be immediately heralded and accepted because of the ethical issues that some have with embryonic stem cells, whether it turns out to be a dead end or not. I have no great insights on this, so go read the articles, or check out the other ScienceBlogs (I happened to check google news, so that's why I hit it first). Update: Ah, I spoke too soon. Devil-boy Jake Young already blogged it. As I thought.
