Scientists discover why poor sleep may harm some brains more

A gene involved in the brain’s overnight cleaning system may change how strongly poor sleep affects Alzheimer’s-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.

AI can tell if your brain is aging faster than you are

A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a …

Scientists find a simple routine linked to less pain and depression

Keeping a regular daily schedule may help reduce pain and depression, especially among older adults with insomnia. Researchers found that consistent times for waking, eating, socializing, and sleeping were linked to better well-being regardless of slee…

Your gut may help your brain decide what to remember

Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus n…

Inside the Backrooms: The internet’s creepiest place is becoming a tourist attraction

The Backrooms began as a single eerie image of empty yellow rooms, but internet users transformed it into a vast fictional world that feels disturbingly real. Through videos, games, maps, survival guides and social media stories, audiences do more than…

APOE2 may protect the brain from Alzheimer’s and aging

The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress. The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzhei…

Lab-grown mini brains may predict which Alzheimer’s treatments will work

Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and pr…

Magic mushrooms may reshape the brain long after the trip ends

A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more pe…

Watching too much TV in midlife may shrink the brain

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along…

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, restorat…
