Abdominal pain is a hallmark of many digestive disorders, including inflammatory bowel disease and irritable bowel syndrome. In an effort to develop targeted treatments for gut pain, scientists have discovered a new enzyme in gut bacteria and are using nanoparticles to deliver drugs inside cells.

Pioneering research finds training service dogs slows biological aging in women, especially veterans with combat experience. One of the most striking findings involved telomere length – a marker of cellular aging. Female veterans in a dog-training program showed increased telomere length while a control group saw declines, suggesting accelerated aging. Despite similar psychological improvements across both groups, including reduced PTSD symptoms and anxiety, only the dog-training group experienced measurable biological gains. The study reveals that emotional stress doesn’t always align with the body’s cellular stress response.
