Will we grow babies outside their mothers' bodies?

A fetus lives in a world of bubbles. In its earliest days, it’s shaped like one. Later, it floats in one-the squishy, enveloping amniotic sac. And eventually, if all goes well, the fetus releases one bubble of fluid, then another and another, like smoke signals, as it puckers and swallows and floats in the womb. It was the bubbles that first convinced Hung-Ching Liu two years ago that a baby might actually be grown outside its mother’s uterus.
