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 ...

The Sun's counterclockwise rotation (as viewed from its north pole) originates from the initial spin of the solar nebula, a remnant of the larger cloud from which it formed. The direction of this spin ...

The study, which observed a periodic wobble in the anti-tail jet of 3I/ATLAS during July and August 2025, indicates that the ...

Generally speaking, the gear mechanism of automobiles and bicycles is usually to increase or decrease the rotation speed in one direction, but by using a special mechanism it is possible not only to ...

A planet's north pole is defined by its position relative to the solar system's invariable plane. The invariable plane is a fixed reference point perpendicular to the solar system's rotation. A planet ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

This file type includes high resolution graphics and schematics when applicable. Engineers who want to measure and control rotating antennas, fluid flow direction, or a robotic arm joint can now use a ...

There is no definitive rule regarding the direction of rotation which is determined how the forces are acting on the electrical coils in the motor of the fan. Why do the blades of a ceiling fan rotate ...

Some of the galaxies that rotate in the same direction as the Milky Way. Credit: Lior Shamir / Kansas State University Since its launch a little over three years ago, NASA’s James Webb Space Telescope ...

A small tectonic plate that is forming on the continent of Africa is rotating in the opposite direction to all the others, and scientists believe they now know the reason why. The microplate, or rift ...

Quite a few Olympic events involve flipping and twisting, including gymnastics, diving, and trampoline. You might ask, "What is the difference between a flip and a twist?" I am going to give my ...
