An anonymous reader writes in with a story about the possibility of having another you in the future. "Human cloning could happen within the next half century, claims a Nobel Prize-winning scientist. Sir John Gurdon, the British developmental biologist whose research cloning frogs in the 1950s and 60s led to the later creation of Dolly the sheep in 1996, believes that human cloning could happen within the next 50 years. He said that parents who lose their children to tragic accidents might be able to clone replacements in the next few decades. Gurdon, who won this year's Nobel Prize for Physiology or Medicine, said that while any attempts to clone a human would likely raise complex ethical issues, he believes that in the near future people would overcome their concerns if cloning became medically useful."
