Scientists find signs of extreme aging and youth in the same 117-year-old
A comprehensive biological study of a 117-year-old woman reveals a duality of extreme aging markers alongside signs of healthy longevity. Researchers used multi-omic analysis to understand how her body simultaneously exhibited cellular decay and protective genetic traits.
Why it matters
This research provides critical insights into the biological mechanisms of aging, potentially paving the way for future treatments that target age-related decline.
For roughly two centuries, human life expectancy climbed steadily as medicine, sanitation, nutrition, and healthcare improved. More recent research, however, suggests that this long upward trend may now be leveling off in developed countries. If that is the case, the next major challenge may no longer be simply preventing disease, but understanding aging itself.
That raises a fundamental question: what actually happens to the body as it ages, and could those biological changes someday be treated in much the same way as disease?
A research team led by Dr. Manel Esteller, Head of the Cancer Epigenetics group at the Josep Carreras Leukaemia Research Institute, has now published the final peer-reviewed results from an unusually detailed study of Maria Branyas, the Catalan woman who lived beyond 117 years.
