Researchers in California have created an incredibly small robot that needs no battery or wired power supply to zip through ...

Physicists have discovered that electronic excitations in 2D magnets can interact through spin waves – ripples in a material’s magnetic structure. This breakthrough allows excitons (electron-hole ...

A tiny, soft, flexible robot that can crawl through earthquake rubble to find trapped victims or travel inside the human body ...

Designing a small-scale flying robot posed significant challenges. Traditional flying robots rely on onboard power sources ...

The amount of magnetic energy packed into these tiny, shiny objects has led to technological ... and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without ...

Like a bumblebee flitting from flower to flower, a new insect-inspired flying robot created by engineers at the University of ...

Their extremely small size is possible as they are powered not by motors but by external magnetic fields. Current robotic surgical tools are typically driven by cables connected to electric motors.

"While warm, this magnetic drum is loose, and its magnetic spins, which are natural turns in particles that make them act like small magnets, are in a disordered phase. But once cold, the drum ...
