For more than a century, scientists have understood that three factors control pupil size: light, focus distance, and ...

Practical problems such as breathing at high altitude have in recent years focused attention on the marvelous system that brings oxygen to the blood and removes ...

Throughout his life, Mitchell saw the detailed mechanism of respiration in this far broader sense: Membrane proteins can create gradients across a membrane, and these gradients can in turn power work.
