Woo Suk Hwang revisited

In February 2004, South Korean stem-cell researcher Woo Suk Hwang rose to scientific superstardom on claims that he had created stem cells from cloned human embryos. But his research was later revealed to be fraudulent. Although many assumed his career was ruined, Hwang has continued to work, cloning hundreds of dogs, cows and other animals, and trying to rebuild his reputation.
In this collection, Nature looks back at the Hwang scandal, the impact it had on the life sciences and what the researcher has been up to since his fall from grace.
