Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in ...

Small Molecule Restores Mitochondrial Function in POLG Disorders Researchers at the University of Gothenburg have identified a small molecule, PZL-A, that restores function in the defective POLG ...

The mitochondrial Complex I plays a central role in cellular respiration and energy metabolism. The ~1 Megadalton L-shaped protein complex is the largest protein assembly of the respiratory chain and ...

The researchers identified the structure of this machine, the mitochondrial pyruvate carrier (MPC), and 50 years since its discovery, have shown how it operates like the lock on a canal to ...

Now biologists have discovered that it happens early—in fact, human sperm's few mitochondria contain virtually no DNA at all. The findings were published in a recent issue of Nature Genetics.

By using scanning electron microscopy, the researchers constructed three-dimensional images of the placental cells and the mitochondria they contained. Now, said Lewis, “We've got this gap where the ...
