Nearly every cell in your body depends on mitochondria to survive and function properly. Mitochondria provide 90% of our ...

Many of us remember from high school biology class that mitochondria are the cell's "power plants." These small kidney-bean-shaped structures are what convert nutrients from food into ATP—the cell's ...

Using new super-resolution microscopes, researchers at the University of California, Irvine and the University of Pennsylvania have for the first time observed electrical charge and discharge ...

Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, Salk researchers have discovered a new function of mitochondria: they set off molecular ...

Remember mitochondria? Those little "powerhouses" of the cell that many of us learned about in high school biology? It turns ...

Spaceflight is no picnic for the body. Muscles atrophy, bones thin, arteries stiffen, inflammation spikes, vision deteriorates—and that’s just for starters. But a new study shows that these disparate ...

Telomere damage drives T cell exhaustion. Antioxidants restored their cancer-fighting strength in mice. Tumor environments place heavy stress on immune cells that fight cancer. Limited oxygen, ...
