For decades scientists have been trying to develop an artificial womb that would re-create a natural environment for a premature baby to continue to develop in, and it looks like they have actually developed one!
In this zip lock bag are tubes of blood and fluid in which eight fetal lambs continued to develop much like they would have inside their mothers. Over four weeks, their lungs and brains grew, they sprouted wool, opened their eyes, wriggled around, and learned to swallow.
The main challenges in the process was re-creating the circulatory system that connects mom to fetus.
In future, this device could be used to bring premature human babies outside the uterus, but yet it has only been tested on sheep.
The lambs spent four weeks in the external wombs and seemed to develop normally.
