## Summary

Old, worn-out cells pile up in joints and drive arthritis as we age. Scientists built a tool that sneaks into these zombie cells and physically rewires their DNA structure, calming them down. In rats with arthritis, it targeted the bad cells while sparing healthy ones. This is early lab work, but it points to a new way of fighting aging cells.
