Researchers discover why 'zombie cells' accumulate with age

As we grow older, our bodies accumulate "zombie cells"—living cells that have stopped dividing or functioning normally but linger in our tissues, contributing to chronic inflammation and age-related diseases.

The research also points to a potential strategy for helping the body rid itself of these cells.
