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, ...

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

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 single genetic “switch” may be the secret to how the body’s cleanup crew grows up and keeps our organs running smoothly.

The genetic network of BTB zinc finger transcription factors and Eip93F is crucial for Kenyon cell identity regulation and neuronal function acquisition in the construction of Drosophila mushroom ...

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 ...
