Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria allows us to make the fuel we need from sugars, a process vital to all life on Earth.

Scientists at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out the structure of this machine and shown how it operates like the lock on a canal to transport pyruvate—a molecule generated in the body from the breakdown of sugars—into our mitochondria.

Known as the mitochondrial pyruvate carrier, this molecular machine was first proposed to exist in 1971, but it has taken until now for scientists to visualize its structure at the atomic scale using cryo-electron microscopy, a technique used to ...

Researchers have identified a novel mechanism underlying hair thinning and loss during aging...

Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their hair, the mechanisms underlying this fate have been a mystery. Hair follicle stem cells (HFSCs), which generate the sacs or follicles that produce hair, keep hair growth going repeatedly over time.
