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. ...

Deep-sea osmolyte makes biomolecular machines heat-tolerant

Researchers have discovered a method to control biomolecular machines over a wide temperature range using deep-sea osmolyte trimethylamine N-oxide (TMAO). This finding could open a new dimension in the application of artificial ...

Mystery solved about the machines that move your genes

Fleets of microscopic machines toil away in your cells, carrying out critical biological tasks and keeping you alive. By combining theory and experiment, researchers have discovered the surprising way one of these machines, ...

DNA origami to scale-up molecular motors

Researchers have successfully used DNA origami to make smooth-muscle-like contractions in large networks of molecular motor systems, a discovery which could be applied in molecular robotics.

Keeping our cells stable: A closer look at microtubules

Microtubules help to regulate cell structure. A group of Japanese researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable and regulates microtubule-based transport within ...
