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 ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Aging, neurological diseases and our bodies’ stress response are all linked to the tiny power plants inside each cell known as mitochondria. To function properly, mitochondria must first read ...

Mutations accumulated in mitochondrial DNA associated with aging were earlier believed to cause aging by decreasing the energy-producing function (mitochondrial respiratory function). In this study, ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

Scientists have found DNA in the nucleus of brain cells, where it shouldn’t be. Bits of genes that typically reside in mitochondria insert themselves at unexpectedly high rates into brain cells’ ...

Back in the 19 th century, as the US grappled with the aftermath of the Civil War, Jesse James, leader of a notorious gang of outlaws, rose to prominence. He robbed banks and trains for over a decade ...

Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria, the 'powerhouses' of our cells, allows us to make the fuel we need from sugars, a ...
