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 ...

The motor protein dancing in all our cells

Motor proteins drive many of the essential processes in our cells. They move with a dancing motion, as Professor Erik Schäffer and his team have shown in a new study. In order to observe the tiny proteins, which are measured ...

Molecular microscopy illuminates molecular motor motion

A toddler running sometimes loses footing because both feet come off the ground at the same time. Kinesin motors that move materials around in cells have the same problem, which limits how fast they can traverse a microtubule ...

Biological tools create nerve-like polymer network

Using a succession of biological mechanisms, Sandia National Laboratories researchers have created linkages of polymer nanotubes that resemble the structure of a nerve, with many out-thrust filaments poised to gather or send ...

Experiments show hypothesis of microtubule steering accurate

Tiny protein motors in cells can steer microtubules in the right direction through branching nerve cell structures, according to Penn State researchers who used laboratory experiments to test a model of how these cellular ...

Some motor proteins cooperate better than others

Rice University researchers have engineered cells to characterize how sensitively altering the cooperative functions of motor proteins can regulate the transport of organelles.
