This Is Not Science Fiction. Israeli Researchers Have Grown an Embryo Outside the Womb

In Jacob Hanna's lab at the Weizmann Institute, for the first time in the world, scientists succeeded in growing a mammal embryo outside the womb. The implications of this unprecedented achievement could be enormous: From growing synthetic embryos for organ implants, to creating an infant whose biological parents are two men. No less

An embryo floats in a bath of warm liquid. Transparent, folded into itself, like all embryos. There’s the large head with a round eye in it, the red heart and the spinal cord that extends, vertebra by vertebra, to the curled-up tail. Anyone might think it’s a regular embryo (human or mouse – at this stage of development both species sport a tail). But no.
