Reversing Heart Aging with Cardiomorphs

Scientists just hacked the human heart using tiny lab-grown organs. They created these

things called Cardiomorphs, which are basically self-organizing mini-hearts with actual veins and

nerves. They used them to study a rare genetic killer called Kearns-Sayre syndrome where the

heart's energy batteries fail. Here is the wild part. They found that

common beta-blockers, drugs we already use, actually force the heart cells to eat

their own broken mitochondria and grow fresh, healthy ones. It literally restored

the heartbeat. This proves we might be able to reverse cellular aging without complex gene editing,

just by flipping a switch in how our cells breathe.
