When a cell senses the damage, one of the substances it produces is a protein called c-GAS. That plays several roles, but what was of interest to these scientists is that in humans, it interferes with and hampers the process by which DNA is knitted back together.

Scientists think that this interference could promote cancer and shorten our lifespan.

In naked mole rats though, the researchers found that the exact same protein does the opposite. It helps the body mend strands of DNA and keeps the genetic code in each cell intact.

They don’t know why or how yet for the mole rat using the same pathway in a different way.
