It gets messier and messier. "Eight premature baby lambs spent their last month of development in an external womb that resembled a high-tech ziplock bag. This technology, if it works in humans, could one day prove lifesaving for the 30,000 or so babies each year that are born earlier than 26 weeks into pregnancy. It could also complicate—and even jeopardize—the right to an abortion in an America in which that right is predicated on whether a fetus is “viable."
