Cannabis use among older adults is rising fast, but today’s marijuana is far more potent than many people realize — and experts warn the risks may be underestimated. Stanford Medicine specialists say modern cannabis can increase the chances of hear…

Scientists have uncovered evidence that serotonin — the same brain chemical boosted by many antidepressants — may actually worsen tinnitus. Using advanced light-based brain stimulation in mice, researchers identified a serotonin-driven circuit link…

UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause h…

Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum — a brain region tied to reward, motivation, and decision-making — that was about 10% larger on average than …

Creatine might be famous in the gym, but its real story is far more interesting. Naturally produced in the body, it helps power cells by rapidly regenerating ATP—the fuel that keeps muscles, the brain, and even the heart running during intense activi…

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 cogni…

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. …
