Of Mice and Men

National Geographic has produced a special examination of the experiments by Fred Gage and others involving the creation of mice with human neuronal stem cells, which begins with this nice piece about the ethical implications.

Previously, New York Times/AP covered the trajectory of the research and the continuing public debate about it, but not particularly well. Rick Weiss describes the implications of the work without laying on the "yuck factor" nonsense about mice turning into Mickey.
