A major international review has found "exercise addiction" is real but far rarer than you might think. Researchers warn that dedication to fitness is often mistaken for addiction, which is instead marked by a loss of control—training through injury, illness or at the expense of work and relationships. The message isn’t to exercise less, but to exercise smarter, prioritising recovery, wellbeing and balance over relentless “no days off” culture.

Psoriasis is a chronic inflammatory skin disease affecting more than 60 million people worldwide, characterized by painful red patches, scaling, and skin thickening. While existing biological treatments largely focus on calming hyperactive T cells in the skin, complete disease resolution remains challenging. Now, a research team led by scientists at Kumamoto University has uncovered a hidden communication network between the skin and the bone marrow that drives psoriatic inflammation. Published in EMBO Molecular Medicine, the study highlights a crucial, previously underappreciated role for neutrophils—first-line immune defense cells—and proposes a promising new target for future therapies.

Texas A&M University researchers have created HemaDyne, a new pump inspired by accordion bellows that can accurately replicate human blood flow patterns in organ-on-a-chip systems, enabling more realistic studies of vascular disease, drug responses and the effects of aging and spaceflight on human health.

Women who experience pregnancy complications face an increased risk of developing peripheral artery disease later in life, according to a new UTHealth Houston study.

Rice University mechanical engineers and Baylor College of Medicine neurosurgeons have identified simple changes to surgical tools that could reduce strain on the esophagus and potentially lower the risk of swallowing difficulties after neck surgery. The study, published in the Journal of the Mechanical Behavior of Biomedical Materials, focuses on anterior cervical discectomy and fusion, or ACDF, a common procedure used to treat damaged or degenerating discs in the neck.
