Summary

Story summary

Duke University researchers developed an experimental blood test that predicts two-year survival for seniors aged 71 and older with up to 86% accuracy.
The test analyzes piwi-interacting RNAs (piRNAs) in blood samples.
Lower piRNA levels correlate with longer survival.
The approach outperforms traditional indicators such as age and lifestyle.
Researchers plan to study how treatments or lifestyle changes affect piRNA levels and explore therapies to promote healthy aging.
