Artificial intelligence is colliding with a hard physical limit: the energy and heat of conventional chips. As models scale ...

Magnets are found all over the place. They hold items on the refrigerator while also holding the door shut. Our banking cards have magnetic strips — as do speakers, motors, and automatic doors.

Pigeons may sense Earth’s magnetic field using their inner ear, sending signals to brain areas that help with navigation and memory.

At some point, you've probably heard the stern warning: Never put magnets near your electronics! It's advice so ingrained in tech culture that it feels like a law of physics. But is it true? Was it ...

Led by researchers at Lancaster University, the international team showed that subtle electronic effects can greatly amplify how magnets respond to ultrafast light. The findings deepen scientific ...

Theoretical physicists have discovered that so-called 'frustrated magnets' can produce skyrmions, tiny magnetic vortices that may be used in memory storage. This discovery opens up a new class of ...

I was recently gifted a charming, kitschy magnet, and as I tucked it into my wallet for safekeeping, I couldn't seem to remember: Do magnets spell doom for credit cards? Many of us have held onto ...
