By Michael Irving July 26, 2022 A new study has found evidence that alcohol may accelerate biological aging Depositphotos A comprehensive new Oxford study has added to the growing body of research highlighting the health effects of alcohol. The large-scale genetic analysis suggests that alcohol consumption directly accelerates aging, by shortening telomeres. Alcohol is among...
ELIFE Scientists have shown how accelerated biological aging measured by an epigenetic clock may increase the risk of bowel cancer, according to a report published today in eLife. The study provides evidence that biological age might play a causal role in the increased risk of certain diseases, and paves the way for interventions that could...
May 5, 2020 — A study just released by Columbia University Mailman School of Public Health is reporting a blood-DNA-methylation measure that is sensitive to variation in the pace of biological aging among individuals born the same year. The tool – DunedinPoAm — offers a unique measurement for intervention trials and natural experiment studies investigating...
by Melissa Healy But scientists are cataloging far subtler signs of biological aging, evident long before hair is lost and skin starts to crinkle. Most of us think we know what aging looks and feels like. It announces itself with wrinkled skin and gray, thinning hair. It blurs vision, makes joints creaky, and if not...
