by Karolinska Institutet Credit: The Journal of Physiology (2025). DOI: 10.1113/JP287205 Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study, published in the Journal of Physiology, shows that the pupil is smallest during inhalation and largest during exhalation—something that could affect our vision. Like the aperture in...

Electrostatic Face Mask Self-Charges with Breathing
FEBRUARY 23RD, 2023 CONN HASTINGS MATERIALS, MEDICINE, PUBLIC HEALTH Researchers at City University of Hong Kong have developed an electrostatically charged face mask that can replenish its charge through the wearer’s breathing action. The electrostatic charge helps the mask to adsorb tiny particles, such as SARS-CoV-2 viruses. However, such masks typically lose their charge and ability to...
