“Forever chemicals” known as PFAS have quietly infiltrated everything from nonstick pans to food packaging—and now new research suggests some of them may be speeding up the aging process itself. In a nationally representative U.S. study, two lesser-known PFAS compounds, PFNA and PFOSA, were found in 95% of participants and strongly linked to faster biological aging in men aged 50 to 64.

A massive study of more than 270,000 people has uncovered a surprising link between a common amino acid and how long men live. Researchers found that higher levels of tyrosine—an amino acid found in protein-rich foods and often marketed as a focus-boosting supplement—were associated with shorter life expectancy in men, potentially trimming nearly a year off lifespan.

Researchers discovered that immune cells shed this outer layer to help them exit the bloodstream and enter inflamed skin. This challenges the long-held idea that only blood vessel walls changed during this process. The finding could help guide new therapies aimed at controlling harmful inflammation.
