Addiction often isn’t about chasing pleasure—it’s about escaping pain. Researchers at Scripps Research have discovered that a tiny brain region called the paraventricular nucleus of the thalamus (PVT) becomes hyperactive when animals learn that alcohol eases the agony of withdrawal. This circuit helps explain why people relapse: their brains learn that alcohol brings relief from stress and anxiety. Read more

Ohio State researchers have discovered that exhausted T cells collapse under the weight of misfolded proteins, activating a destructive stress response called TexPSR. Unlike normal stress systems, TexPSR accelerates protein production, flooding the cells with toxic buildup. Blocking it restored T-cell function and improved cancer immunotherapy. Read more

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This newly discovered mechanism, visualized in real time with advanced microscopy, shows mitochondria acting like emergency first responders rather than static power plants. The structures, called NAMs, were also identified in patient tumor biopsies, suggesting real-world relevance to cancer’s spread. Read more
