Cured in America

In the UK, political debate over stem cells continues to focus on whether scientists should be allowed to create hybrid humananimal embryos. This futuristic research may eventually lead to rewarding discoveries about incur-able diseases - and emotive arguments by some religious groups trying to ban it should be resisted. At the same time, some scientists and patient advocates have been unable to resist hyping hybrid embryo research, by implying that it could produce cures in the near future. Sir Martin Evans, the stem cell pioneer and Nobel prizewinner, acknowledged that this week.
