(From CNN). The American Medical Association has stepped up to the plate to endorse theraputic cloning and stem cell research. This is an important event in the ongoing political fight over medical research. In addition to taking a pro-science stance, the AMA is backing a future in which real anti-aging, regenerative medicine will be widely available. Every major group that takes this position will make it harder for the anti-research forces in the halls of power to legislate against medicine.
