Leveraging a single regression model based on conserved cytosines, we can now measure age in all mammalian tissues. This pan-mammalian epigenetic clock model confirms that aging is conserved across mammalian species at select regions of the DNA, which will accelerate the applicability of research findings from model organisms to humans.
