Stem cell scientist Xiangzhong "Jerry" Yang, who cloned the first farm animal in the United States, died of cancer last week. He was 49. Yang directed the University of Connecticut's Center for Regenerative Biology and, in 1999, a Holstein called Amy that Yang cloned was born. "Jerry was one of the greatest scientists and cloning pioneers of our time," Robert Lanza, chief science officer at Advanced Cell Technology of Worcester, told the Hartford Courant.
