NEW YORK (AP) — Scientists in Oregon have created embryos with genes from one man and two women, using a provocative technique that could someday be used to prevent babies from inheriting certain rare incurable diseases.

The researchers at Oregon Health & Sciences University said they are not using the embryos to produce children, and it is not clear when or even if this technique will be put to use. But it has already stirred a debate over its risks and ethics in Britain, where scientists did similar work a few years ago.

The British experiments, reported in 2008, led to headlines about the possibility someday of babies with three parents. But that’s an overstatement. The DNA from the second woman Login to read more
