STEM CELL UPDATE: I should have mentioned this story the other day, but somehow forgot. Anyway, there looks to be more progress with adult stem cells, as opposed to the embryonic kind. Here’s a nice survey of the topic.

As I’ve noted before, this only eliminates one class of ethical objection to stem cell research, but it’s still important. It would certainly be good news for the Bush Administration, which is dreadfully out of step with public opinion on this topic. However, the article notes that adult stem cells can’t do everything, and I suspect that research with embryonic stem cells will be required in order to learn how to get more out of adult stem cells, though of course I could be wrong.
