Every second an artery stays blocked, heart muscle dies — and open-heart surgery isn’t fast enough. That’s why doctors use a coronary stent. A catheter snakes through your wrist or groin to the exact site of the blockage. A balloon inflates, and a tiny metal mesh tube — smaller than your fingertip — locks the artery open permanently. Circulation restored. Heart muscle saved. Patient walking out

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

The US is falling apart because its violating the 3 laws of the individual inside of the sovereignty circle. In this video, I explain what those 3 laws are, how the US is violating them, and how they fit inside of the sovereignty circle. I also explain how you as an individual can begin to abide by them in your own life in order to take back control. If you have questions feel free to leave them in the comments. Save this and share it with someone who needs to see it #anticapitalism #democracy #
