New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...

Scientists have pinpointed precise regions in the human genome where DNA is most likely to develop a mutation. At spots where RNA polymerase 'opens' your DNA to read and copy instructions – known as ...

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 ...
