CLONING Scientists had cloned sheep, pigs, cattle, mice, rabbits, horses and cats but, until this year, never a dog. Man's best friend, it turns out, is extremely difficult to duplicate. It was Woo Suk Hwang and his team at Seoul National University who finally succeeded in turning a single cell from the ear of an Afghan hound into a genetically identical puppy. Hwang was back in the news last week when he admitted lying about the source of some of the human eggs used in an earlier stem-cell experiment. Nevertheless, many scientists suspect the techniques Hwang perfected...

"Being too focused on scientific development, I may not have seen all the ethical issues related to my research," a grim Hwang said at a news conference in Seoul, announcing he would step down as head of the newly created World Stem Cell...

Despite the scandal, Hwang, who says he'll continue his research, remains a hero at home?last week more than 600 Korean women signed up to donate their eggs. That reaction worries Ku In Hoe, a bioethicist at Catholic University in Seoul. "Korea's representative scientist just turned out to be a liar," she says. "We should not try to cover this...
...publishing a correction in coming weeks concerning the source of the eggs, clarifying that the donors had not, as the study originally stated, all been unpaid volunteers. After that, he said, they will await the reports from the investigations conducted by the South Korean Ministry of Health and by Seoul National University, where Hwang is a faculty member, and where he will continue to do stem cell research, to determine whether the integrity of Hwang's results were compromised in any way. So far, that does not seem to be the case. "We have no reason to doubt the scientific...
...professor of medical science at the Catholic University of Korea in Seoul and a member of the Korean Bioethics Association, described Korean reaction as "very emotional and very supportive" of Hwang's research: "They are enraged at the idea that ethical concerns could block scientific advances." She said government and media are confusing the public by obscuring the real issue-that "Korean science has lost credibility in the world." Seoul National University's oversight committee announced that its investigation showed no ethical or legal problems, she notes, but "Korea's representative scientist just turned out to be a liar...
