Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...

Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

If we could listen to stem cells closely enough, we might hear them whisper, “mechanosenses tingling.” After all, stem cells sense and react to the physical forces around them, maintaining their ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...

A ketogenic diet - one that is high in fat and extremely low in carbohydrates - has been known for decades to reduce seizures ...

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

West Feliciana High School AP Biology students are studying cell signaling pathways by comparing effectiveness of commercial ...

Among the most promising tools of cancer therapy, engineered immune cells known as chimeric antigen-receptor (CAR) T cells have already transformed the treatment of blood cancers. Yet, despite their ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...
