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…

MIT scientists found that what we see is strongly influenced by how alert or active we are. Parts of the brain responsible for planning and control send specialized signals that either boost or quiet visual details. These areas seem to balance each oth…

Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified molecules that influence how long memories persist. Ea…
