More Work for Stem Cell Scientists, More Gagging for the Rest of Us

In the New York Times, Andrew Pollack has a story on the long road ahead now that researchers have figured out how to make embryonic-looking stem cells out of adult cells. "Scientists still face the challenge of taking that abundant raw material and turning it into useful medical treatments, like replacement tissue for damaged hearts and brains," he writes.

And for those of you interested in losing your lunch, be sure to check out this item from Wired. Evidently, US President Bush has already taken credit for the latest breakthrough. Policy advisor Karl Zinsmeister was quoted as saying, "I don't think there's any doubt that the president's drawing of lines on cloning and embryo use was a positive factor in making this come to fruition." In case that's not enough, you can follow the links to the National Review Online, where people have already begun thanking Bush for his "courageous leadership." Now, if you'll excuse us, GTO needs to find an airsickness bag.
