Osaka, Japan - Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also ...

PITTSBURGH—Researchers from the University of Pittsburgh and the University of Chicago were able to control heart muscle function in a new way after discovering the previously unknown role of two ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

Mammalian hearts have almost no ability to grow new heart muscle cells, called cardiomyocytes, after birth. Thus, dead tissue after an adult heart attack is not repaired with new cardiomyocytes. It is ...

The heart is a muscle like no other, beating 60 to 100 times per minute on average, around the clock. But when it grows weak, it can lead to serious problems: from debilitating shortness of breath and ...
