The skeletal muscles of men and women process glucose and fats in different ways. A study conducted by the University Hospital of Tübingen, the Institute for Diabetes Research and Metabolic Diseases of Helmholtz Munich and the German Center for Diabetes Research (DZD) e.V. provides the first comprehensive molecular analysis of these differences. The results, published in Molecular Metabolism, possibly give an explanation for why metabolic diseases such as diabetes manifest differently in women and men—and why they respond differently to physical activity.

Skeletal muscles are far more than just “movement driving motors...

Flinders Health and Medical Research Institute researchers, along with colleagues in the UK and U.S., have linked brighter night-time light exposure to elevated risks of five major cardiovascular diseases.

Circadian rhythms govern fluctuations in blood pressure, heart rate, platelet activation, hormone secretion, and glucose metabolism. Long-term disruption of those rhythms in animal and human studies have produced myocardial fibrosis, hypertension, inflammation, and impaired autonomic balance. Previous research efforts relied largely on satellite-derived estimates or small cohorts using bedroom or wrist light sensors, leaving personal exposure patterns uncharted at population scale.

In the study, “Personal night light exposure predicts incidence of car...

A pioneering new study published in Nature Microbiology, led by J. Oriol Sunyer, professor of immunology and pathobiology at the School of Veterinary Medicine, and a team of researchers at Penn Vet and the University of New Mexico, has uncovered a surprising new player in gut health: an antibody called secretory immunoglobulin M (sIgM).

While another antibody, secretory immunoglobulin A (sIgA), has long been known for helping balance the bacteria in our intestines, this new research shows that sIgM may be just as vital—if not more so—in protecting gut health and maintaining overall well-being.

Secretory immunoglobulins—immunoglobulins found in the mucosal surfaces ...

Capital Medical University, in collaboration with the Chinese Academy of Sciences, reports that betaine, a molecule produced in the kidney and enhanced through sustained exercise, operates as a potent inhibitor of inflammatory and aging-related pathways.

Regular physical activity boosts health across cardiovascular, metabolic, and neurological systems. Scientists have traced improvements in immune function, insulin sensitivity, clearing of senescent cells and tissue regeneration to consistent physical activity. Earlier animal studies suggested that long-term exercise can delay aging processes and reduce vulnerability to chronic disease.

Precise molecular explanations for how sustained exercise reshapes human biology remain incomplete...
