Stress measured in hair could predict depression and anxiety in children

Researchers from the University of Waterloo discovered that measuring long-term stress through children’s hair samples can reveal early signs of mental health risks in those living with chronic physical illnesses. Children with persistently high cort…

The sleep switch that builds muscle, burns fat, and boosts brainpower

UC Berkeley researchers mapped the brain circuits that control growth hormone during sleep, uncovering a feedback system where sleep fuels hormone release, and the hormone regulates wakefulness. The discovery helps explain links between poor sleep, obe…

Autism symptoms vanish in mice after Stanford brain breakthrough

Scientists at Stanford have found that hyperactivity in the brain’s reticular thalamic nucleus may drive autism-like behaviors. In mouse models, drugs and neuromodulation techniques that suppressed this overactive region reversed symptoms, hinting at…

Experts warn: Smartphones before 13 could harm mental health for life

Getting a smartphone before age 13 may drastically increase the risk of poor mental health later in life, according to data from more than 100,000 people. Early use is linked to suicidal thoughts, aggression, and detachment, largely driven by social me…

A 3-minute brainwave test could spot Alzheimer’s years before symptoms

Scientists at the University of Bath have developed a simple three-minute brainwave test called Fastball EEG that can detect memory problems years before Alzheimer’s is typically diagnosed. Unlike traditional memory tests, it passively records brain …

Why Alzheimer’s attacks the brain’s memory hub first

Virginia Tech researchers are investigating how overloaded mitochondria in the brain’s memory circuits may spark early Alzheimer’s damage. Their work focuses on calcium signaling and how it might trigger breakdowns in the entorhinal cortex.

Study finds cannabis improves sleep where other drugs fail

A long-term study following insomnia patients treated with cannabis-based medical products revealed sustained improvements in sleep quality, mood, and pain management over 18 months. Most participants reported better rest and less anxiety or depression…

Scientists reveal how breathwork unlocks psychedelic bliss in the brain

High-ventilation breathwork with music can evoke psychedelic-like states, shifting blood flow in the brain and reducing negative emotions. Participants experienced unity and bliss, pointing to a natural therapeutic tool with powerful potential.

Stronger weed, higher risk? Potent THC linked to psychosis and addiction

A sweeping review of nearly 100 studies has raised concerns about the mental health impacts of high-potency cannabis products. Researchers found strong links to psychosis, schizophrenia, and cannabis use disorder, while results for anxiety and depressi…
