Last night I saw Paul McCartney. What struck me during Let It Be, sung from his 83y voice (+1000s singing along), is these songs now carry the weight of a lifetime, many lifetimes. Incredible example of longevity, connection, impact. Grateful he still shares his gift and that we get to sing along.

Closing out the year with an exciting new publication demonstrating IL-23R is senescence-associated biomarker of aging. Thanks to our awesome team for making this study happen! www.nature.com/articles/s43...
IL-23R is a senescence-linked circulating and tissue biomarker of aging - Nature Aging
Using mouse and human plasma, Carver et al. identify factors that are altered with age and test which are reverted by a panel of genetic and pharmacological senolytic interventions in aged mice. They ...
