For patients with heart failure, blood pumps can be lifesaving. But the very forces that sustain circulation can also harm it, damaging red blood cells through hemolysis and compromising the body's ...

Researchers have used supercomputers to model how red blood cells deform and become damaged in mechanical circulatory support devices, such as blood pumps used for heart failure patients. The study ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...
