Congrats @prof_horvath @UCLAHealth, great talk. Universal clock, Lu et al. @NatureAging 2023: https://t.co/5YI0Ca4VBY Androgen clock, Sugrue et al. @PNASNews 2025: https://t.co/ERwIHv3anm @torisugrue @epi_otago @ARDD_Meeting #ARDD2026 Tracking the sc…
What is fun for me to see is that if you read carefully you may predict how an author may think in future & future opportunties as horvath published pan-mammalian clock 10 years after the first paper. https://t.co/hwh99agbzu
4/ And if cross-species timing is your standard, epigenetics passes it spectacularly: as I already mentioned, pan-mammalian methylation clocks predicted age across 185 species and 59 tissues at r > 0.96, from mice to 200-year bowhead whales: https:…
3/ Meanwhile, pan-mammalian epigenetic clocks trained on 12k samples from 185 species (from mice to 200-year bowhead whales!) predicted age at r > 0.96. Awkward for the claim that epigenetics is too “unstable” to be a conserved clock. https://t.co/0N…
