The implication for abortion is clear. If Americans can see the unborn baby growing visibly in a ziplock bag, they are going to be hard pressed to argue about murdering the bag next to it.
In April, researchers announced they had managed to keep several extremely premature lambs alive and growing in artificial wombs. After spending up to four weeks in a clear plastic “extra-uterine device” at the Children’s Hospital of Philadelphia, each sheep transformed from a decidedly undercooked fetal specimen to a much more robust critter with long limbs and a fluffy wool coat, the sort of animal you wouldn’t be terribly alarmed to see plop to the ground in a field on a spring afternoon.
The setup strongly resembles a sous vide cooking apparatus: a tiny, tender lamb floats in a large plastic ziplock, hooked up to tubes and monitors. But a video clip posted by the researchers has the emotional heft of feeling a fetus kick when you put a hand on a pregnant woman’s belly. Visible through the clear plastic, the lamb’s hooves twitch gently as it snuffles its nose and wiggles its ears.
The lambs in the experiment were selected for their developmental similarity to human babies born right on the edge of viability, or about four months premature. Babies born that early are equal parts horrifying and marvelous. Tiny creatures with organs visible through their translucent skin, they’re often called “miracle babies.” But there’s nothing particularly mysterious about those little beings curled up in nests of tubes and wires; they live because of the inspiration and hard work and risk-taking and study and pain of hundreds of people, writes Katherine Mangu-Ward.
