A breakthrough in the understanding of how mammals create red blood cells could lead to opportunities for artificial blood to ...

In addition to calpain, erythrocytes express another calcium-dependent enzyme, tissue transglutaminase (TG2). 4 In human red blood cells (RBCs), Ca 2+-induced TG2 activation results in ...

NASA's SpaceX Crew-3 astronauts headed to International Space Station 02:04. A new analysis has found that space travel can lower red blood cell counts, leading to a condition known as "space anemia." ...

Space travel is known to be notoriously rough on the human body, but new research has revealed just how hard it hits red blood cells. A new study of astronauts showed that they lost 54% more red ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Iron deficiency anemia is when your body lacks red blood cells due to loo little iron in your body. Learn about the signs of low iron, its causes and more.

A.S. Smith et al., “Myosin IIA interacts with the spectrin-actin membrane skeleton to control red blood cell membrane curvature and deformability,” PNAS, 115:E4377–85, 2018. Healthy red blood cells ...

The mature red blood cell is released to perform its oxygen-carrying work throughout the body and, like all our cells, ages and dies after about three months. Its iron is reused by the bone marrow ...

New research has revealed that red blood cells function as critical immune sensors by binding cell-free DNA, called nucleic acid, present in the body's circulation during sepsis and COVID-19, and ...

For many years, scientists assumed that blood production took place in the bone marrow. But now, researchers at UC San Francisco are showing it’s also happening in the lungs. They found hematopoietic ...

Red blood cells. Your red blood cells have a protein called hemoglobin, which gives them their red color. When you breathe in oxygen, it binds to the hemoglobin and is carried throughout your body.

When researchers stiffened red blood cells with a chemical, the effect of low oxygen on speed disappeared. The results reinforce the complex and important role of blood in the brain.
