Having pioneered the study of muscle physiology in mammals, she uncovered how ion channels enable muscle movement.

Among 11 infants treated to date, most survived and their heart function improved.

The extracellular matrix appears to inhibit regeneration; but scientists debate whether heart muscle really comes back.  

Cardiologists have found a way to cool the human heart in a localized way to help reduce muscle damage from heart attacks. 

Research in human patients and mice reveals the role of the circadian clock in the risk of heart damage at different times of day.

From guiding branching neurons in the developing brain to maintaining a healthy heartbeat, there seems to be no job that the immune cells can’t tackle.

In addition to circulating in the blood as immune sentinels, macrophages play specialized roles in different organs around the body.

High-resolution MRI reveals that human fetal hearts rapidly develop their major structures within a four-day period.

Mitochondria age differently depending upon whether they’re located in the liver, heart, or kidney, scientists find in flies and mice.
