Two members of the President's Council on Bioethics who expressed positive views on therapeutic cloning have been replaced, as reported at Reuters. Various commentators are expressing surprise, but the role of the council has always been to provide justification for anti-research policies. It hasn't been doing that job so well of late, so it was time to stack the deck a little more. This indicates that the current administration is still very serious about banning stem cell and therapeutic cloning research. The cost of blocking research into regenerative and healthy life extension medicine is already unthinkable ... are we going to let them get away with this, or are we going to do something about it?
