Researchers in South Korea have become the first to successfully clone a human embryo, and then cull from it master stem cells that many doctors consider key to one day creating customized cures for diabetes, Parkinson's and other diseases.
This is not cloning to make babies, but to create medicine.
But it immediately revived controversy over whether to ban all human cloning, as the Bush administration wants, or to allow this "therapeutic cloning" that might eventually let patients grow their own replacement tissue.
