The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's ...

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, ...

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.

Cell-to-cell junctions were visualized by ZO1-GFP, and the dynamics of cell junctions were captured by movies. When the cells indicated by * were spontaneously stretched, a continuous belt of cell ...

A study published in Nature Communications describes how lymphatic endothelial cells assist in generating robust immune memory, offering new insights into how the immune system functions. Subscribe to ...

Short-term IF boosts glucose homeostasis, but prolonged fasting in adolescence may impair β cell maturation—potentially linking chronic IF to type 1 diabetes risk. Study: Chronic intermittent fasting ...

Learn more about the impact ultramarathon running has on red blood cells and how it may do more harm than good for the body.

Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a study published in the American Society of Hematology's journal Blood Red ...
