SCIENTISTS GROW WHOLE MODEL OF HUMAN EMBRYO, WITHOUT SPERM OR EGG

Summary from the TLDR newsletter

Scientists from the Weizmann Institute have grown embryo models that resemble real early human embryos without using sperm, eggs, or a womb. The embryo models look like a textbook example of a real 14-day-old embryo. They release hormones that turn pregnancy tests positive in the lab. Realistic embryo models could provide an ethical way for scientists to study the earliest moments of life. The scientists claim that it would be impossible to achieve a real pregnancy using their embryo models.
