Ultrashort radio waves reportedly boost brain waste clearance in Alzheimer's mouse models

A reply describes an October 2026 Science Advances mouse study of 40.68 MHz ultrashort radio waves, not acoustic ultrasound. It says the waves boosted brain waste clearance in healthy mice within 10 minutes. After seven days of treatment, Alzheimer's-model mice had less amyloid-β and improved cognition, though human translation remains unproven.
