Scientists have known for decades that somatic mutations in DNA is the limiting factor.

Apparently what this research group has accomplished is that
they are using the latest DNA sequencing techniques to deepen the understanding and perform systematic studies.

Dr Inigo Martincorena, the senior author of the study, said: “Ageing is a complex process, the result of multiple forms of molecular damage in our cells and tissues.

“Somatic mutations have been speculated to contribute to ageing since the 1950s, but studying them has remained difficult.

“With the recent advances in DNA sequencing technologies, we can finally investigate the roles that somatic mutations play in ageing and in multiple diseases.”
