Don't Call it a Comeback

Along with 30 other researchers Hwang Woo-Suk, the disgraced South Korean stem cell researcher, has taken up a post at a private lab outside of Seoul. Kim Sue, a member of Hwang's lab, told the Associated Press that they have extracted stem cells from embryonic cloned pigs and cows. Hwang, accused of acquiring research money under false pretenses, embezzlement and buying human eggs, might not be able to restore his credibility. "This would be a very quick reformation and we'd have to worry about recidivism," said Curt Civin from Johns Hopkins in this news story.
