Killifish Show Staged Aging Predicts Lifespan
Stanford researchers tracked 81 African turquoise killifish continuously and analyzed billions of video frames, identifying 100 behavioral 'syllables' and finding that early midlife behaviors (days 70–100) predict total lifespan. They observed stepwise aging with 2–6 rapid transitions and linked predictive behavioral shifts to coordinated liver gene-expression changes published in Science on March 12, 2016. Findings imply wearable-collected behavior might reveal human aging stages.
