Elizabeth Jonas first got interested in mitochondria by chance. In 1995, she was a postdoctoral researcher at Yale, working at the Marine Biological Lab in Woods Hole, Massachusetts, where she was ...

Dysfunctional mitochondria, organelles that serve as cellular power generators, appear to cause the symptoms of Gulf War ...

NEW YORK, NY (March 26, 2025)--Everything the brain does—from storing memories to interpreting sights to regulating emotions—requires energy, all produced by cellular organelles called mitochondria.

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 ...

Scraps of DNA discarded by our neurons' power units are being absorbed into our nuclear genome far more frequently than assumed, potentially putting our brains at greater risk of developing ...

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’ ...

New research shows that when mitochondria are transplanted from astrocytes to damaged neurons after a brain hemorrhage, they promote healing. The healthy mitochondria from the astrocytes stimulate the ...

A new study shows metformin enhances myelin repair in human-based models by tuning mitochondrial metabolism, offering hope for multiple sclerosis treatment. Study: Metformin alters ...

In 1817, a British physician named James Parkinson published An Essay on the Shaking Palsy, describing for the first time cases of a neurodegenerative disorder now known as Parkinson’s disease. Today, ...

Everything the brain does—from storing memories to interpreting sights to regulating emotions—requires energy, all produced by cellular organelles called mitochondria. However, surprisingly little is ...
