Woo Suk Hwang

The South Korean stem-cell researcher Woo Suk Hwang has been at the centre of one of the largest investigations of scientific fraud in living memory.

In January 2006, Hwang's home research institution, Seoul National University, delivered a damning report about Hwang's work on cloned human embryos, concluding it was all based on fraudulent data. The revelation has destroyed the best evidence so far that stem cells can be extracted from a clone matched to a specific patient. With Hwang discredited, both the field of therapeutic cloning and the public's trust in science have suffered a serious setback.

Here Nature news collects all our material about the case.
