MIT researchers have discovered a brain circuit that drives vocalization and ensures that you talk only when you breathe out, and stop talking when you breathe in. The newly discovered circuit ...

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation ...

Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the lungs through the branched ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

New research reaffirms what many of us have known for years: Longer exhalations calm the autonomic nervous system, reduce physiological arousal, lower stress, and take the edge off anxiety. Graphical ...

Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, ...
