Researchers from Queen Mary University of London have identified a new mechanism in which adhesive structures within the cells of the heart sense stiffness through muscle contractions and resting tension at the same time.

Every year, a small but not insignificant number of babies are born with hearts whose muscles are spongy and thin, although exactly what causes that condition isn't clear. Now, Stanford biologists think they may have found ...

In mammals, including humans, the cells that contract the heart muscle and enable it to beat do not regenerate after injury. After a heart attack, there is a dramatic loss of these heart muscle cells and those that survive ...

The human heart is particularly vulnerable to viruses. That's because cardiac myocytes, the heart muscle cells that give your heart its ability to "beat," have one major weakness – they don't reproduce themselves to repair ...
