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.

The art of folding mitochondrial membranes

Oliver Daumke's lab figures out how the inner membranes of mitochondria "get their groove" and assume the complex shapes they need to carry out crucial cellular functions.

How nature engineered the original rotary motor

The bacterial flagellum is one of nature's smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting ...

Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in ...

Evolution of mitochondria

Mitochondria are the power stations of human cells. They provide the energy needed for the cellular metabolism. But how did these power stations evolve, and how are they constructed? Researchers from the University of Freiburg ...

Building scaffolds in the cell's power stations

A group of scientists led by Assistant Professor Dr. Martin van der Laan has decoded the molecular basis for the characteristic structures inside of mitochondria. Mitochondria are the powerhouses of cells and contain microscopic, ...
