A significant new study published on September 17th in the open-access journal PLOS Medicine offers compelling evidence that the architecture of our sleep—specifically the time spent in REM and deep sleep cycles—plays a critical role in long-term health outcomes. Conducted by Shengzhi Sun of Capital Medical University in China and a team of colleagues, the…

Your brain and the ocean share an unexpected feature: waves. Beneath the surface of our conscious thoughts, electrical activity flows across the brain’s landscape in rhythmic patterns known as traveling brain waves, or neural traveling waves. Much like the swells that roll across the sea, these patterns are dynamic and multifaceted. They arise from a…

A pioneering analysis of biological aging has revealed a striking connection between sleep habits and the internal clockwork of the human body. The research suggests that both insufficient and excessive sleep are associated with accelerated aging in critical organs—including the brain, heart, lungs, and the immune system—and are deeply intertwined with a broad spectrum of…

For decades, the prevailing scientific understanding of clinical depression centered on the "chemical imbalance" theory, specifically the belief that deficiencies in neurotransmitters like serotonin were the primary drivers of the disorder. However, groundbreaking new research from the Columbia University Vagelos College of Physicians and Surgeons suggests that the roots of depression are far more complex,…
