Everyday DNA mutations can help us understand immune function and aging—and even mitigate harm caused by some inherited ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

As we age, our cells accumulate DNA mutations. If any of these mutations confer a growth advantage to a self-renewing or long-lived progenitor cell, its lineage can expand. The progenitor cells that ...
