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 blood pressure, brain signaling, and immune defenses. But when levels go unchecked, it can damage cells and disrupt normal signaling.
