A clinical trial has demonstrated that a virtual prevention intervention reduced cannabis and alcohol use among American Indian and Alaska Native emerging adults. In this study, published in JAMA Network Open, researchers tested the efficacy of a program called Traditions and Connections for Urban Native Americans (TACUNA) that blends evidence-based and traditional practices to prevent substance use and bolster cultural connections.

Heart disease is the leading cause of death in the United States, according to the Journal of the American College of Cardiology. Its impact extends beyond biology, with social determinants such as food insecurity, socioeconomic status and education influencing outcomes.

A new study of sunscreens, baby lotions, shampoos, soaps and other everyday products found that nearly all contained chemicals not disclosed on their labels. Most contained at least one unlabeled chemical with known or suspected health hazards, and one in four contained a chemical that contradicted claims on the package, including “phthalate-free” products that contained phthalates. The research is published in Environment & Health.

With temperatures forecast to climb to 36°C (97°F) in parts of the UK, heat health alerts are once again in place—and for many people, it will mean more than an uncomfortable few days.

In a study conducted at the Universities of Jyväskylä and Eastern Finland, more screen time since childhood was associated with better cognitive processing in adolescence. According to one of the researchers, we should not regard screen time solely as harmful. The most important thing is to find a balance between physical activity and screen time that promotes active thinking.

Long-term diabetes management requires continuous blood glucose monitoring to detect abnormalities early and intervene in time. However, conventional fingertip blood sampling is both painful and inconvenient, while most continuous glucose monitoring (CGM) products currently available on the market rely on biological enzymes—requiring regular replacement, incurring higher costs and demanding stringent storage conditions.

Inside the human body, powerful natural antioxidants often face a destructive journey. Ellagic acid, a bioactive polyphenol abundant in berries and walnuts, possesses remarkable antioxidant, anti-inflammatory and health-promoting properties.

Fatty fish has long been viewed as “brain food” that supports cognitive health through anti-inflammatory, antioxidant and vascular mechanisms. That has led researchers to ask whether the benefits of fatty fish might extend to Alzheimer’s disease prevention. But the answer may not be that simple, according to a new study by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University.

Adults who do both aerobic and muscle-strengthening exercises are less likely to develop a raft of chronic diseases, researchers have found.

New research investigated the dietary preferences of 9,000 Australians, finding that people whose diets included foods with higher levels of ‘bitterness’ had healthier, more nutritious diets.

Replacing 15 minutes of sleep or sedentary behavior with 15 minutes of movement was each linked to a 2% reduced risk of cancer, new UCL research has found.
