A nano-gear in a nano-motor inside you

Diverse cellular processes require many tiny force-generating motor proteins to work in a team. Paradoxically, nature often chooses the weak and inefficient dynein motor to generate large persistent forces inside cells. Here ...

Nanoshuttle wear and tear: It's the mileage, not the age

As nanomachine design rapidly advances, researchers are moving from wondering if the nanomachine works to how long it will work. This is an especially important question as there are so many potential applications, for instance, ...

Researchers reshape basic understanding of cell division

By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single ...

Bionanomachines: Proteins as resistance fighters

(PhysOrg.com) -- Friction limits the speed and efficiency of macroscopic engines. Is this also true for nanomachines? A Dresden research team used laser tweezers to measure the friction between a single motor protein molecule ...

Nanotech researchers develop artificial pore

(PhysOrg.com) -- Using an RNA-powered nanomotor, University of Cincinnati (UC) biomedical engineering researchers have successfully developed an artificial pore able to transmit nanoscale material through a membrane.

New molecular force probe stretches molecules, atom by atom

Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.
