Longevity & AgingHuman Lifespan May Be Hitting a Biological Ceiling, New Research Warns
A wave of new longevity research suggests humans may be approaching a hard biological limit on lifespan. In the world's longest-living populations, life expectancy has risen only 6.5 years since 1990 despite accelerating medical advances. A PNAS study finds no generation born after 1939 will reach 100 on average. On a more hopeful note, a genomic study from Leiden University identified four regions likely harboring longevity genes and 12 rare protein-altering variants, including one tied to inflammatory DNA-damage response. Separately, researchers are calling for a systems-level rethinking of aging science, moving away from single-target therapies toward coordinated modulation of multiple biological networks simultaneously.
