GLP-1 drugs like semaglutide--best known for treating diabetes and driving weight loss under the brand names Ozempic and Wegovy--may also deliver a surprising mental health boost. In a massive study tracking nearly 100,000 people over more than a ...

Drugs designed to clear amyloid beta from the brain--once seen as a promising path to slowing Alzheimer's--may not actually help patients in any meaningful way, according to a major review of over 20,000 participants. Even more concerning, they may . ...

Coffee doesn't just energize--it actively reshapes the gut and mind. Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. Decaf even improved learning and memory, while caffeine ...

A hidden force may be quietly shaping how you feel--and you'd never even know it. Infrasound, an ultra-low-frequency vibration below the range of human hearing, is everywhere from traffic to old buildings. In a small experiment, people exposed to it ...

The brain's memory center may begin life more like a crowded web than an empty canvas. Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time. ...

A new analysis of the "Boltzmann brain" paradox suggests our memories and sense of reality could, in theory, be random illusions born from cosmic chaos. By uncovering circular reasoning in how physicists think about time and entropy, the study raises ...

Scientists have discovered a way to help the brain clean itself of harmful Alzheimer's plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells that ...

Free-living amoebae are emerging as a global health concern, fueled by warming temperatures and outdated water systems. While many are harmless, some can cause deadly infections and even protect other dangerous microbes. Their ability to survive heat ...

Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles--even slightly--your brain may gently sway inside your skull. This subtle motion, triggered by pressure changes . ...

Building muscle doesn't have to mean exhausting workouts or soreness. Researchers found that slow, controlled "lowering" movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like chair ...
