More good stem-cell news

The story is here.

UPDATE:  Or maybe not.  Reader Jonathan Watson writes:

I disagree with you that being able to harvest stem cells from embryos without killing them is a good thing. I think it raises the prospect of embryos kept in some sort of horrible "stasis," Scientists figure out how to stimulate embryos to produce stem cells constantly and consistently who would then be farmed for the results. Death saved these embryos previously from becoming miniscule slaves to science - now they may live forever in some sort of twilight. Huxley's "Brave New World" keeps coming up and true in different ways.

Hmmm.
