Microplastics may be quietly damaging your brain and fueling Alzheimer’s and Parkinson’s

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Sc…

Depression may start with an energy problem in brain cells

Researchers have discovered a surprising change in how cells produce energy in people with depression. Brain and blood cells in young adults with major depressive disorder produced more energy molecules at rest but had trouble increasing energy product…

Brain scans reveal how ketamine quickly lifts severe depression

A new brain-imaging study has revealed how ketamine produces its fast antidepressant effects in people with treatment-resistant depression. Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ketamine …

A new “magic mushroom” drug could treat depression without psychedelic hallucinations

Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that st…

Golden Retriever genes linked to anxiety, aggression, and intelligence in humans

Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits like…

Scientists discover the brain protein that drives cocaine relapse

Cocaine addiction isn’t simply a failure of willpower — it’s the result of lasting biological changes in the brain. Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward s…

Beyond amyloid plaques: AI reveals hidden chemical changes across the Alzheimer’s brain

Scientists at Rice University have produced the first full, dye-free molecular atlas of an Alzheimer’s brain. By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend bey…

The more you fear aging, the faster your body may age

Worrying about getting older—especially fearing future health problems—may actually speed up aging at the cellular level, according to new research from NYU. In a study of more than 700 women, those who felt more anxious about aging showed signs of…
