Making Fake Yangs

Can't we just make a new Yang?
Xiangzhong "Jerry" Yang, a stem cell scientist who successfully cloned the first farm animal in the United States, has died after a long battle with cancer. He was 49.Yang, director of the Center for Regenerative Biology at the University of Connecticut, died Thursday at Brigham and Women's Hospital in Boston, school spokesman David Bauman said Friday. In 1999, Yang put UConn on the world's scientific map when a Holstein named Amy was born in Storrs. She was the first cloned farm animal in the United States. The world's first cloned animal was Dolly the sheep, created in 1996 in Scotland. But Yang died before achieving one of his dreams: the cloning of a human embryo for potentially lifesaving stem cells.
