In a bid to save the endangered giant panda, Chinese scientists have successfully cloned an embryo and will try to implant it in a host animal’s uterus. The researchers had initially thought they would need three to five years to be successful in their effort, but they now believe they can produce a cloned panda in less time. Only about 1,000 pandas survive in the wild, and about 100 in zoos. Pandas reproduce infrequently and researchers warn they could go extinct within 25 years.
