A new study suggests that eating more fat rather than less could help the body gain greater benefits from exercise when blood sugar levels are high, offering an unexpected perspective on how diet and physical activity work together to support metabolic health.

A popular fitness trend among young people may be quietly undermining their sleep. A new study led by researchers at the University of Toronto has found that teenagers and young adults who use pre-workout supplements are significantly more likely to experience extremely short sleep durations.

A massive international brain study has revealed that memory decline with age isn't driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time.

A high-fat diet does more than overload the liver with fat. New research from MIT shows that prolonged exposure to fatty foods can push liver cells into a survival mode that quietly raises the risk of cancer.

When two people work on a shared task, they process information alike, a new study revealed.

Hypertension may impair the brain far earlier than previously understood -- even before a measurable rise in blood pressure occurs -- according to a new preclinical study from Weill Cornell Medicine. The changes help explain why hypertension is a major risk factor for developing cognitive disorders, such as vascular cognitive impairment and Alzheimer's disease.

Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people and one strain moves as fast as swine flu.

A new study led by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard suggests that a Mediterranean-style diet may help reduce dementia risk.

An international team of scientists has now discovered that people gain more weight on an ultra-processed diet compared to a minimally processed diet, even when they eat the same number of calories.

A Mediterranean-style diet, in combination with reduced caloric intake, moderate physical activity, and professional support for weight loss, may cut the risk of type 2 diabetes (T2D) by 31%, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health.
