Summary

Story summary

Researchers at the Max Planck Institute for Biology of Ageing identify a molecular process linked to aging-related inflammation.
The study shows mtDNA uses RNA building blocks when DNA building blocks are scarce, causing instability and ejection from mitochondria.
Publication in Nature; preventing these replication mistakes could yield therapies for healthier cells in old age.
