Inside Woosuk Hwang’s puppy clone mill:
Hwang snips open the amniotic sac and the little fur ball slips out into the world. It’s black, wet – and motionless. An assistant wraps it in a towel, massages it gently – and it starts to yelp. Success!
This puppy is a sign of things to come for Hwang and his lab. For the past few years, the lab has worked on cloning domestic dogs… So can work like Hwang’s actually help conserve endangered species? Many researchers are far from convinced. Some feel the lab is operating in a vacuum and its work could even hurt existing conservation efforts.
What are the long term effects of cloning? Are humans next?
