The panel at Seoul National University (S.N.U.) put it bluntly: "This kind of error is a grave act that damages the foundations of science." Dr. Hwang Woo Suk, South Korea's famous stem-cell researcher, had fallen from grace. An S.N.U. investigation into Hwang's groundbreaking experiments in human cloning...
