A Fading Muscle Fat Molecule May Explain Why Strength Slips With Age

Climbing stairs, hauling groceries and catching a stumble all lean on fast-twitch fibers, the type that tends to fade first with age.

Fat Infiltration into Muscle Tissue as a Biomarker of Aging

An important goal in the research community is to build a robust measure of biological age, the burden of age-related damage and dysfunction contributing to disease and mortality, that can be used to rapidly assess the quality of any potential intervention to slow or reverse aging. One of the reasons why the longevity field moves slowly is that, in the absence of a robust measure of biological age, it takes a long time to assess any given therap…
