Topics · Measuring aging
Measurements are clues—not added healthy years.
These stories show what a biomarker or physiology measurement captured, then keep it separate from function, disease, healthspan and lifespan.

Sex-specific aging clocks found differences—and large limits
The models exposed sex-dependent patterns across organs and health outcomes. They did not become clinical tests, individual forecasts or evidence that aging was slowed.

The latest evidence on aging clocks and biomarkers
Newest first, using each story’s primary category. Evidence scope describes what was reviewed; it is not a score.
Sex-specific aging clocks found differences—and large limits
The models exposed sex-dependent patterns across organs and health outcomes. They did not become clinical tests, individual forecasts or evidence that aging was slowed.
Human biomarkers and health associations · multimodal model-development studyRead the storyRentosertib moved protein-based aging clocks in a small IPF analysis
Six proteomic clocks shifted in a 42-person ancillary analysis, but the result does not establish slower aging, healthspan, lifespan or benefit in healthy people.
Human biomarkers · exploratory ancillary trial analysisRead the storyA CT-derived age gap tracked disease risk in one screening cohort
The model was associated with prevalent and incident disease and added little discrimination beyond chronological age; it is not a reason to obtain CT imaging.

Cold-water studies measure thermogenesis—not longer life
A small study of young male winter swimmers found physiology differences. It did not test disease, function, healthspan or lifespan, and it cannot show that cold exposure caused the findings.

Hyperbaric oxygen changed selected blood-cell markers—not aging itself
A small uncontrolled study reported telomere and senescent-cell changes in selected blood-cell subtypes. It did not test clinical aging, healthspan or lifespan, and commercial conflicts matter.
Human blood-cell biomarkers · uncontrolled pre/post studyRead the storyWhat an epigenetic clock can—and cannot—tell you
Different clocks target different constructs. A score is not a diagnosis, and changing it does not prove longer life.
