South Korea’s pioneering stem cell scientist has cloned a dog, smashing another biological barrier and reigniting a fierce ethical debate — while producing a perky, lovable puppy.
The researchers, led by Woo-Suk Hwang, insist they cloned an Afghan hound, a resplendent supermodel in a world of mutts, only to help investigate human disease, including the possibility of producing stem cells for treatment purposes.
But others immediately renewed calls for a global ban on human reproductive cloning before the technology moves any farther.
Whether you agree with these scientific practices or not, you have to admit that it's pretty neat.
