Neighborhood Deprivation Linked to Faster Epigenetic Aging via Adversity

TL;DR: A 2026 preprint in medRxiv linked higher neighborhood deprivation to faster DNA-methylation aging in 370 healthy adults, with lifetime adversity explaining part of the association and stronger direct effects among Black participants. Key Findings Yale s…

DNA Methylation Clock Ages Differed Across Saliva and Blood Samples

TL;DR: A 2026 study in Epigenetics found that DNA methylation clocks, which estimate biological aging from chemical marks on DNA, gave substantially older age estimates in saliva than in two blood-derived samples from 91 early-to-mid-adult participants. Key Fi…
