The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...

The human heart has the ability to repair itself, scientists have found, in a breakthrough that could provide a lifeline for hundreds of thousands of patients. When someone has a heart attack or heart ...

The heart is a very resilient muscle. Scientists observed heart muscle cells regenerating in mice studies after a heart attack. Their heart muscle cells, called cardiomyocytes, were observed dividing ...

A groundbreaking study shatters the myth of permanent cardiac damage, revealing that the heart can naturally trigger cell ...

Physician-scientists found that a subset of artificial heart patients can regenerate heart muscle, which may open the door to new ways to treat and perhaps someday cure heart failure. A research team ...

When heart muscle gets damaged, the result is often permanent. Unlike other muscles in the body, the heart has long been believed to lack the ability to heal itself. But recent research suggests that ...

Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each ...

Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce ...
