Alzheimer’s breakthrough: Scientists restore two hours of sleep without clearing brain plaques

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged.

The mysterious hum heard around the world may finally have an explanation

The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external.

Scientists discover why ozempic may not work for some people

Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." In several clinical trials, carriers were significantly less likely to reach healthy blood sugar targets while taking GLP-1 medications.
