Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, i t delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments. ...read more read less
