A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

RIVERSIDE, Calif. -- 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 ...
