A major new meta-analysis finds that vegetarian and vegan diets can support healthy growth in children when properly planned. Kids on plant-based diets often had better heart health markers, including lower "bad" cholesterol, and consumed more fiber ...

Long before opioids flooded communities, something else was quietly changing--and it may have helped set the stage for today's crisis. A new study finds that as church attendance dropped among middle-aged, less educated white Americans, deaths from . ...

Researchers have revealed that so-called "junk DNA" contains powerful switches that help control brain cells linked to Alzheimer's disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that ...

In a rare and historic achievement, Children's Hospital Colorado successfully completed its first dual heart and liver transplant in a pediatric patient. The life-saving surgery was performed on 11-year-old Gracie Greenlaw, whose congenital heart ...

Spending a few hours a week helping others may slow the aging of the brain. Researchers found that both formal volunteering and informal acts, like helping neighbors or relatives, were linked to noticeably slower cognitive decline over time. The ...

A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed better metabolism, stronger muscles, and healthier fat ...

A new bioluminescent tool allows neurons to glow on their own, letting scientists track brain activity without harmful lasers or fading signals. The advance makes it possible to watch individual brain cells fire for hours, offering a clearer, deeper ...

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked ...

Firefighter turnout gear is designed to shield first responders from extreme heat and danger, but new research suggests it may also introduce chemical exposures. A U.S. study found that brominated flame retardants are present across multiple layers . ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some cancers and how it could be improved for others.
