A five-month-old baby boy has been revealed as the first kid in the world with three biological parents, reports New Scientist. The baby boy was apparently conceived by a technique that has been legally approved in the UK, and lets parents with genetic disorders have healthy babies. Though, the method used in this particular cases was slightly different from one legalized in the UK. From the report: Zhang (a doctor) took a different approach, called spindle nuclear transfer. He removed the nucleus from one of the mother's eggs and inserted it into a donor egg that had had its own nucleus removed. The resulting egg -- with nuclear DNA from the mother and mitochondrial DNA from a donor -- was then fertilised with the father's sperm. Zhang's team used this approach to create five embryos, only one of which developed normally. This embryo was implanted in the mother and the child was born nine months later. "It's exciting news," says Bert Smeets at Maastricht University in the Netherlands. The team will describe the findings at the American Society for Reproductive Medicine's Scientific Congress in Salt Lake City in October.
