Not a lot of time to post, so I'll just throw the link your way. Link.
I hope this can stay non-P&C. What I take from this article is that these new AFS cells are not as completely useful as their embryonic counterparts, but are far more useful than adult stem cells, making them a nice alternative to pissing off pro-life government types for a lot of research. I'm afraid some research (and likely all research intended to create products for human consumption,) will eventually need at least cursory testing with embryonic stem cells, but we can hopefully make the need as small as possible. If all these do is partly diffuse the political situation surrounding this research, it's still an enormous step.
