A reproductive quirk of some reptiles, insects, and other species may help stem cell researchers sidestep ethical debates over the use of human embryos. Researchers at Advanced Cell Technology in Worcester, Massachusetts, report on page 819 that they have isolated the first stem cell lines from primate parthenotes, embryos grown from unfertilized eggs that, in mammals, are not capable of developing into viable fetuses.
