Scientists clone monkeys for the first time
Ever since cloning produced Dolly the sheep, scientists have copied a slew of mammals ranging from dogs to ponies. Primates, however, have been elusive -- until now. Chinese researchers have successfully cloned a macaque monkey fetus twice, producing sister monkeys Hua Hua and Zhong Zhong using the same basic method used to create Dolly. The team removed the nucleus from monkey eggs and replaced it with DNA from the fetus, implanting the resulting eggs in female monkeys for them to give birth.
Dolly the sheep's clones are healthy, thank you
When Dolly the cloned sheep fell victim to premature aging, lung disease and osteoarthritis, that triggered many fears. Is cloning safe? Would her fellow clones also meet an early end? Apparently, you can relax. A University of Nottingham study shows that four of Dolly's genomic clones (Daisy, Debbie, Denise and Dianna) are healthy, with no conditions that suggest they're aging too quickly. Some showed early signs of osteoarthritis, but that's normal for their advanced age. In short: cloning, if all goes well, is safe.
