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 ...

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 ...

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cells in the human brain, according to the latest ...

Our biceps and our brain cells may have more in common than previously thought. New research led by the Lippincott-Schwartz Lab shows that a network of subcellular structures similar to those ...

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, ...

Modulating miR-21 signaling may work to reduce heart damage in people with pulmonary hypertension (PH), a preclinical study suggests.

An often-ignored type of cell in the brain plays a dynamic and surprisingly complex role in our ability to process information, according to new research. An often-ignored type of cell in the brain ...
