A new study suggests depression may soon be detectable through a simple blood test--by tracking how certain immune cells age. Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and ...

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 . ...

Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors. Rather than ...

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 ...

Long before humans spread across the globe, a deadly disease may have quietly shaped where our ancestors lived--and even how we evolved. New research reveals that malaria didn't just threaten early human survival; it actively pushed populations away ...

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 ...

Physicists are rethinking one of quantum mechanics' biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous "collapse" processes--possibly linked to gravity--could subtly blur time itself. This wouldn ...

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 ...
