A surprising discovery at UC San Diego suggests that chronic lower back pain may become deeply embedded in the brain's sense of personal identity. Researchers found that movement-triggered pain activates a brain network associated with self-awareness and memories, even though ordinary acute pain typically shuts this network down. This unexpected difference could explain why conventional pain medications often provide limited relief and why fear, anticipation, and past experiences can intensify chronic pain.

Scientists have identified a weakened brain signal that may connect several seemingly unrelated symptoms of schizophrenia, including sensory processing difficulties, disorganized speech, and greater symptom severity. The surprising discovery could help explain the disorder's underlying mechanisms and potentially lead to earlier detection and new treatments.

NASA’s Artemis I mission has revealed that cosmic radiation near the Moon is higher than in Earth orbit, but not by as much as scientists might expect. Tiny experimental detectors also uncovered surprising details about how radiation passes through the human body, offering valuable insights for future lunar exploration.

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determine whether they develop into long-lasting memory cells that protect against future infections.

A surprisingly simple exercise routine could help lower blood pressure without requiring daily workouts or expensive equipment. In a study of 100 adults, researchers found that wall squats performed just once or twice a week helped maintain significant reductions in systolic blood pressure over the short term.

Regular exercise does more than strengthen the heart. New research reveals that it actually reshapes the nerves controlling how the heart functions, and the changes are surprisingly different on the left and right sides of the body.
