Tiny sensors harvest energy from blinks, eyebrow raises, jaw movements and even pulsing arteries. Prototype glasses tracked behaviors associated with bruxism, including jaw clenching and teeth tapping. System uses machine learning to recognize six facial activities with 93.8% accuracy. Ultra-low-power design could pave the way for smart glasses that continuously monitor health without constant charging.

Findings could help researchers understand how spaceflight affects brain and heart health over time

Researchers at Gladstone Institutes have uncovered a uniquely counterintuitive class of bacterial defenses. More than just a biological curiosity, decoding these complex systems provides a molecular blueprint that scientists can adapt to engineer more efficient DNA-editing tools for human health and therapies.

A Concordia study of 64 bariatric surgery candidates found no significant differences in cardiometabolic health between people with distinct dietary patterns. Both groups shared characteristics of a Western diet, including high sugar and fat intake and insufficient fibre. The findings suggest broad dietary improvements may matter more than targeting specific eating habits.
