Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to significantly fewer NK c…

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These finding…

Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility an…

Researchers discovered that a tiny structural feature of the enzyme GPX4 helps keep neurons safe. A rare mutation removes this protection, allowing harmful molecules to damage cell membranes and trigger early dementia. Mouse and cell studies showed cha…

Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a patient with severe obesity. Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the bra…

Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both health and reproduction. Evidence ranging from global …

Scientists uncovered a surprising four-layer structure hidden inside the hippocampal CA1 region, one of the brain’s major centers for memory, navigation, and emotion. Using advanced RNA imaging techniques, the team mapped more than 330,000 genetic si…

Researchers found that people with anxiety disorders consistently show lower choline levels in key brain regions that regulate thinking and emotions. This biochemical difference may help explain why the brain reacts more intensely to stress in anxiety …

Nitrous oxide may offer quick, short-term relief for people with major depression, especially those who haven’t responded to standard medications. The meta-analysis found rapid improvements after a single dose and more sustained benefits after repeat…

A large study of brain scans shows that our neural wiring evolves through five major stages from birth to late old age. These phases are separated by sudden turning points that mark big shifts in how the brain is organized. The most surprising discover…
