Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic symmetry can cancel energy loss.

[Andrey Mikhalchuk] built his own magnetic levitation device and you can too… if you have the patience. He’s not using electromagnets, like the Arduino levitator or the floating globe. Instead, a pair ...

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

A group has created a levitating quadcopter consisting of 4 motors and 4 spinning magnetic arrays. By spinning the magnets over a copper sheet, the 105-lb quadcopter levitates. The magnetic levitation ...

I listened to Rihanna on a levitating speaker. It didn’t sound as good as Rihanna on a middle-range traditional speaker, though it certainly looked more interesting. If you have a small child, miss ...

Some asteroids can barely hold it together. Rather than solid lumps of rock, ‘rubble pile’ asteroids are loose collections of material, which can split apart as they rotate (SN: 3/16/20). To ...

Microplastics are the crumbs of our plastic world, tiny pieces that come from bigger items breaking apart or from products ...

Microplastics are the crumbs of our plastic world, tiny pieces that come from bigger items breaking apart or from products like synthetic clothing and packaging. They’re now everywhere. Scientists ...
