Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come from?

Scientists have found that drinking two to three cups of coffee a day may significantly reduce your risk of developing dementia, but drinking more won't help protect your brain any further.

Questions like "will getting a pet benefit our child's mental health?" are increasingly common and pertinent. In Spain, for instance, more than half of all households now have one or more pets.

The human body is often described in parts—different limbs, systems, and organs—rather than something fully interconnected and whole. Yet many bodily processes interact in ways we may not always recognize. For example, researchers at the University of Missouri School of Medicine may have found a link between high blood pressure and an overactive nervous system.

Could a simple patch, inspired by the weight-loss drug Ozempic, really help you shed excess kilos without the pain and effort of an injection?

Penn State College of Medicine is reporting on two cases of destructive infant meningitis linked to Paenibacillus infection, documenting severe neurologic injury and raising concerns about diagnosis and treatment. Reports from Uganda first linked these organisms to destructive neonatal infections, including cases with abnormal accumulation of cerebrospinal fluid, seizures, and extensive brain injury. Similar cases have since been recognized in multiple U.S. states and routine antibiotic regimens for infant bacteremia and meningitis may be inadequate when Paenibacillus is involved.

By 2030, nearly half of all American adults will have obesity, according to research published in the New England Journal of Medicine. In every single state, researchers expect at least 35% of adults to have a body mass index of 30 or higher, the threshold that defines obesity. That prediction may come as a shock, as weight loss medications like Wegovy and Zepbound become more popular and more affordable.

Almost every golfer has experienced it. You're lined up on the green for that perfect putt, when an easy tap-in shot is foiled by a mysterious twitch. Golfers refer to it as "the yips." And researchers at Mayo Clinic believe they've found a neurological cause to explain some instances.

A randomized crossover weight loss trial in adults with overweight or obesity found that higher protein big breakfasts improved satiety, while higher fibre breakfasts produced slightly greater weight loss and more favourable gut microbiota markers. Both diets improved metabolic biomarkers, but microbiota changes reflected surrogate gut health indicators rather than direct clinical outcomes.

Higher intakes of total, processed, and unprocessed red meat were associated with greater odds of diabetes in a nationally representative sample of US adults. Statistical substitution models suggest replacing red meat with plant proteins, poultry, dairy, or whole grains may be linked to lower diabetes odds, though causality cannot be inferred.
