- Dynamics of genetic and somatic trade-offs in ageing and mortality
A study published in Nature on April 22, 2026, identified 29 genetic loci influencing lifespan and mortality in mice, with effects varying by age and sex, and 30 loci linking body mass to longevity. The research used a population of 6,438 young mice to map DNA variants associated with these outcomes.
- Scientists were wrong about lifespan. Your genes matter way more than we thought
A study from the Weizmann Institute challenges previous beliefs that environment and chance primarily determine lifespan, revealing genetics may account for about half of lifespan differences. Researchers analyzed twin datasets and simulations to isolate genetic influences, uncovering hidden genetic factors that had been overlooked for decades.
