This summer, the National Institutes of Health (NIH) decided to reverse an earlier moratorium on federal funding for research that uses human stem cells to create part-human, part-animal embryos. Research that creates these chimeras, as they are called, may soon be eligible for federal funding under certain carefully controlled conditions.

Wolinetz, Ph.D., Associate Director for Science Policy at the NIH, show the move to be controversial.
