A 6-month study of 120+ adults averaging age 72 found HIIT was the only exercise type that reduced body fat while preserving lean muscle. Here's what older adults should know.

A new Oncoscience study found a vitamin B12-based compound crosses the blood-brain barrier, targets glioblastoma tumors, and boosts treatment effects in animal models.

NB.1.8.1 "Nimbus" is now the dominant COVID strain in the U.S. at ~43% of cases. 10 states report high or very high wastewater levels. Here's what it means and who's at risk.

Promising health tools that seek to predict a person's risk of serious health problems before they happen are rarely being used in everyday health care, according to new Curtin University research. The review, published in The Lancet Regional Health - Western Pacific, found Australia has developed a growing number of tools that can identify people at risk of conditions such as heart disease, falls, frailty and diabetes complications, but very few are being routinely used by health services.

Children growing up in a low-income urban community in Vellore are now facing two seemingly opposite forms of malnutrition simultaneously: persistent thinness and rising obesity by the time they reach primary school age. A longitudinal birth cohort study of 251 children found that while thinness remained common, the prevalence of overweight and obesity nearly tripled between ages 7 and 9, underscoring the country's growing "double burden of malnutrition."

Childhood vaccination rates have slumped globally. In several countries, people are more hesitant about getting vaccinated. Populist political actors promote distrust of government and scientific institutions. And the disinformation economy means we can't agree on the facts behind policy debates.

Researchers at the University of Liverpool have identified distinctive biological characteristics within adenomyosis lesions that could help pave the way for more targeted, less invasive treatments. The findings from a team based in Professor Dharani Hapangama's gynecology research group at the university provide new insights into the common but often underrecognized condition that affects up to 1 in 5 women of reproductive age. Despite its prevalence and significant impact on health and quality of life, adenomyosis has historically received limited attention in research and clinical practice.

Tonight, as you close your eyes in bed, something strange will happen to you: Your mind will drift from an ordinary thought to a dream, but it will be impossible to say exactly when it happened. We tend to imagine that the boundary between being asleep and awake is clear: When we are awake, we think; when we are asleep, we dream. Yet, in our study, published in Cell Reports, we show that this boundary is more porous than you think. You can dream before falling asleep and plan your day ahead after drifting off.

As pro cycling teams have been preparing for the start of the Tour de France on Saturday, extreme heat has rolled across Western Europe, smashing temperature records, cracking infrastructure and taking a toll on the population.

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and necroptosis. Cells use this process when they are damaged, stressed, becoming cancerous, or infected by harmful microbes. This self-destruction mechanism helps to protect the body, but it is also involved in many diseases, such as infections, inflammatory conditions and cancer.
