A single vial of blood could help tell you which drugs to take, foods to eat, and more.

A team of international researchers has developed a new biological age “clock” that estimates how well someone is aging ... to biospecimens including blood, urine, saliva, and dental plaque ...

More information: A Novel Blood-Based Epigenetic Clock for Intrinsic Capacity Predicts Mortality and is Associated with Clinical, Immunological and Lifestyle Factors, Nature Aging (2025).

Consider three studies. “Collectively, organ age gap associations with disease and blood biochemistry demonstrate that aging models derived from organ-specific plasma proteins capture disease-relevant ...

But most of these clocks are built on data gathered from the blood, which limits their accuracy to blood samples. Now, a small team of researchers has created a new epigenetic clock modeled on ...

While chronological age is easily measured, it fails to capture the complex biological processes that determine the rate of aging. A new proteomic aging clock ... in your blood to gauge the ...

quoting a deceleration of his biological aging rate to only 0.64, based on measurements taken by his team. Johnson’s journey—from son-to-father blood swaps to high-tech plasma exchange—may ...

After detaching the old mice, the scientists looked at molecular markers in their blood and liver that act like a clock for ... trials examining plasma exchange for anti-aging in humans offers ...
