How Electricity Controls Your Heartbeat? | Inside the Human Heart

This chart shows human brains size over time. They got way bigger, fast. But now they’re shrinking? (No, it’s not the phones!) About 2 million years ago something changed and it altered the course of human evolution. Our brains just started RAPIDLY growing, the organ nearly doubled in size in just a few hundred thousand years. This turning point is what allowed us to evolve into the intelligent species we are today. But now… To learn more, follow along! #evolution #human origins #science

Учёные создали эмбрион из клетки кожи и сперматозоида. Они взяли ядро с ДНК из клетки кожи, поместили его в яйцеклетку без собственного ядра и оплодотворили. Это значит что теоретически двое мужчин могут зачать генетически родного ребёнка. Технология ещё не готова к широкому применению, но в будущем может изменить лечение бесплодия для всех. #наука #медицина #генетика #технологии #будущее

Circulation restored. Heart muscle saved. Patient walking out
