Timeless Wisdom

New melanoma vaccine results strengthen the evidence for treatment after surgery, but do not establish protection against a first cancer.

Similar nutrient totals and glucose responses can conceal metabolic differences, but those differences do not establish long-term harm.

Oats, experimental peptides and biological-age tests show why the value of a biomarker depends on what it can tell us about health.

Human trials show why better magnesium absorption, higher NAD+ and convenient supplement blends need to be judged against the health outcomes they actually measure.

Trials of metformin, rapamycin and muscle-building drugs reveal why biological changes must be judged against the health benefits they actually deliver.

Research on sleep, neurofeedback and diet reveals why changing a biological signal does not necessarily mean clearer thinking.

Neurofeedback, Alzheimer’s treatments and lifestyle trials reveal why changing a brain measurement is only part of demonstrating a benefit.

Blueberries, neurofeedback and Alzheimer’s treatments reveal why a measurable improvement needs careful interpretation before it becomes a brain-health claim.

Preserving muscle matters, but strength and everyday function need their own measurements, as ageing studies and muscle-preserving drug trials show.

Brain-age scores and genetic findings offer intriguing clues, but decisions about brain health still depend on what studies actually measured.
