Chinese and American scientists have captured headlines with a controversial method to help infertile women have a genetically related baby. The plan involves transferring DNA from the infertile woman's egg and DNA from sperm into a healthy woman's donor egg. The experiment was conducted in China because the U.S. Food and Drug Administration has not approved this type of research in the United States. NPR science correspondent Joe Palca joins guest host John Ydstie to discuss the study.
