Researchers have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, called ...

(Nanowerk News) Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a ...

Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

Background GIRD is a condition resulting in the loss of internal rotation of the glenohumeral joint as compared to the contralateral side. Mechanism of GIRD is caused by repetitive throwing such as a ...

The less work required to translate an object, the better. Avoiding sliding friction — a major sinkhole of applied force for motion — is accomplished through rolling. A: Ironically, with increased ...

Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.
