Urban residents with more greenery within 100 meters (328 feet) of their homes have a 20% lower risk of developing dementia over time, according to a new study from Stockholm University and Karolinska Institute that followed nearly 3,000 older adults for 16 years. Published in the journal Alzheimer’s & Dementia, the study highlights the importance of greenspace in the immediate surroundings of the home for sustainable urban planning that supports brain health.

For decades, boys and men were more likely than their female peers to use nicotine. But a new study from MUSC shows that among U.S. adolescents, that pattern has reversed for vaping.

Ultraprocessed foods have a terrible reputation.

Staying active before surgery may do more than strengthen the body for recovery—it may protect the brain. Regular physical activity at least seven times a week before cancer surgery was linked to a lower risk of developing postoperative delirium, according to research presented at the ANESTHESIOLOGY 2026 annual meeting.

Continuous glucose monitors (CGMs) could transform diabetes management for millions of Americans with type 2 diabetes who don’t take insulin, according to findings published in the New England Journal of Medicine.

To understand what goes wrong in the body, scientists must first know what right looks like. Salk Institute researchers are building a scientific reference, piece by piece, for what makes a body healthy. Their latest effort maps how exercise reshapes the body at the molecular level, examining responses across organs, cell types, sexes and circadian phases in mice.

The disability burden associated with alcohol-related cirrhosis complicated by heart failure is projected to rise substantially by 2050 across Central Europe, Eastern Europe and the United States (US), according to new research presented at UEG Week 2026.

Learning new eating habits isn’t simple. Our preexisting feelings around food—whether it’s a distaste for olives or a love of pastries—could make it harder to learn new eating habits, according to new research from Yale School of Medicine.

Survivors of major trauma can achieve a remarkable rate of recovery when given the right support, according to a new University of Manchester–led study examining a pioneering rehabilitation program developed in response to the needs arising from the Manchester Arena bombing.

Some of nature’s healthful benefits might be possible through well-curated ornamental spaces, suggests a brain activity study recently published in the October issue of Building and Environment from researchers at Drexel’s Nick Howley College of Engineering and Computing. The findings, which reveal new insights into how humans experience nature, may lead to scalable, evidence-based ways to design spaces to produce restorative benefits, which could be especially helpful for those who do not have convenient access to plants outdoors.

A recently published study by University of New Mexico researchers looks at how intense exercise affects the body. Michael Deyhle, an associate professor in the Department of Health, Exercise and Sports Sciences, oversaw the study led by doctoral students Jonathan Specht, Jeremy Ducharme and Alyssa Bailly. The findings are published in the journal Physiological Reports.
