I came across an article from Technology Review titled "Stem Cells Reborn". It discusses how researchers are renewing their race to clone stem cells after the shocking fraud case of Hwang Woo Suk in South Korea, which by now I'm sure that most have heard of.
The article finds that success could mean a new era of more realistic disease models and safer, life-saving regenerative medicine. Now, six months after details of the fraud emerged, ACT and groups at Harvard University and the University of California, San Francisco, among others, are gearing up to start new therapeutic-cloning programs.
I can only imagine the ethical issues that are bound to arise.
