Nanospheres measure the forces of cell motors

Motor proteins generate the forces for essential mechanical processes in our body. On a scale of nanometers—a millionth of a millimeter—motor proteins, for example, power our muscles or transport material within our cells. ...

3-D model shows bacterial motor in action

Nagoya University scientists in Japan and colleagues at Yale University in the US have uncovered details of how the bacterial propeller, known as the flagellum, switches between counterclockwise and clockwise rotation, allowing ...

Tiny protein motor fuels bacterial movement

There are billions of bacteria around us and in our bodies, most of which are harmless or even helpful. But some bacteria such as E. coli and salmonella can cause infections. The ability to swim can help bacteria to seek ...

Exponential scaling of frictional forces in cells

AMOLF researchers have presented a theory that describes the friction between biological filaments that are crosslinked by proteins. Surprisingly, their theory predicts that the friction force scales highly nonlinearly with ...
