Cloned coyotes

Seven years ago, South Korean scientist Hwang Woo-suk was a celebrity. News headlines called him "a pioneer," "doctor clone," "a hero"' of stem cell research. Now he still makes news headlines when he announces his scientific findings, but with an added adjective like "disgraced" and verbs like "claims." In October, Hwang's team announced the world's first cloned coyote. (ABC News)
