From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Gene editing technology allows to introduce and correct disease-linked mitochondrial DNA mutations in liver and skin cells In a step toward treating mitochondrial diseases, researchers in the ...

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 ...

Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. A fundamental discovery is overturning decades of ...

A new study suggests that the mitochondria in human egg cells don't accumulate DNA mutations with age, which sets them apart from other tissues in the body. When you purchase through links on our site ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...
