Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make ...

Scientists have discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make loops into DNA could move in one ...

Capable of changing the direction of permanent magnet motors, a line of reversing polarity toggle switches can also control up/down, in/out, and rotate/counter-rotate motions when used with a relay.

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...
