Light-operated molecular machines can be used to rotate objects much bigger than themselves but at larger scales, they stop rotating once they reach the so-called photostationary state. By using a ...

If you’re into anything even vaguely mechanical on the broad hacking spectrum, you’ve come into contact with things that spin. Sometimes, it’s important to know precisely how fast they are spinning!

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...
