A critical guide to ageing research: what was measured, which limitations matter, and what cannot yet be transferred to clinical practice. A new research summary each week, following source checks.
How we select papers
Our starting point is Aging-US and questions informed by the Polycentric Aging Framework (PAF). Contradictory findings are welcome. We distinguish cell, animal and clinical studies, and separate biomarker changes from functional improvement. PAF is an interpretive framework, not a filter for favourable evidence.
