Mitochondria work much like Tesla battery packs, study finds

For years, scientists assumed that mitochondria—the energy-generating centers of living cells—worked much like household batteries, generating energy from a chemical reaction inside a single chamber or cell. Now, UCLA ...

Keeping a cell's powerhouse in shape

A German-Swiss team around Professor Oliver Daumke from the MDC has investigated how a protein of the dynamin family deforms the inner mitochondrial membrane. The results, which also shed light on a hereditary disease of ...

A microscopic topographic map of cellular function

The flow of traffic through our nation's highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers at the University of Missouri is challenging ...

How a mitochondrial enzyme can trigger cell death

Cytochrome c is a small enzyme that plays an important role in the production of energy by mitochondria. It is also involved in signaling dangerous problems that warrant apoptosis, or programmed cell death. Using solid-state ...

Researchers uncover mechanism of protein transport in mitochondria

The research labs of Dr. Thomas Becker and Dr. Nikolaus Pfanner from the Institute for Biochemistry and Molecular Biology at the University of Freiburg have reported a function of the metabolite channel of the mitochondrial ...

Mechanism helps explain the ear's exquisite sensitivity

The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered ...

Unexpected undulations in biological membranes

How biological membranes - such as the plasma membrane of animal cells or the inner membrane of bacteria - fluctuate over time is not easy to understand, partly because at the sub-cellular scale, temperature-related agitation ...

The importance of asymmetry in bacteria

New research published in Nature Microbiology has highlighted a protein that functions as a membrane vacuum cleaner and which could be a potential new target for antibiotics.
