A study found sucralose and stevia altered the gut microbiome and glucose control in mice, with effects appearing in descendants that never consumed them. It was mice, and that matters more than the headline.
Adults over 40 completed an executive function test 12% faster after a month with a HEPA purifier. The trial was randomised and sham-controlled, but it was a secondary outcome in people living beside highways.
Researchers found that frequent micro-awakenings were associated with higher polygenic Alzheimer's risk in healthy adults aged 50 to 69, but not in younger adults. What that does and does not mean.
A study of more than 17,000 American men linked higher ultra-processed food intake to roughly 30% greater prostate cancer risk. What the design can and cannot establish, and what to do anyway.
Rutgers researchers found waist circumference performed as well as a complex new obesity definition, and that BMI alone missed many people with obesity-level body fat. Our own NHANES analysis found the same gap.
A study linked long-term melatonin use to 90% higher heart failure risk. It was never peer-reviewed, it studied prescription records, and the design cannot separate the supplement from the insomnia.
AD109 cut breathing interruptions by 44% in a Phase 3 trial and is now under FDA review. How it works, who it might help, and why it is not a CPAP replacement for most people.
A randomised trial matched weight loss across three diets and still found the ketogenic arm cut liver fat by 67% versus 45%. Why matched weight loss makes this important, and the limits of 55 people over five months.
In 1973 a biochemist sewed two mice together and proved fat tissue talks to the brain. Twenty-one years later they found the hormone. Then the drug failed — and that failure explains why weight comes back.
Moderna and Merck's personalized mRNA cancer therapy met its Phase 3 endpoints in resected melanoma. How it works, how it started, and the caveats most coverage omits.
