Explainer: the mysterious missing magnetic monopole

Physicists have theorised about the existence of a magnetic monopole for decades, but we have yet to find one.

Using lasers to make data storage faster than ever

The speed comparison between today's technology and femtosecond spintronics is like comparing the fastest bullet train on Earth to the speed of light.

I’m stuck like glue: why I love magnets and you should too

I have a confession: I’m obsessed with magnets. We rely on magnets every day, but seldom give them a second thought. There are magnets in your credit card, your cellphone, your car, microwave oven and…

Magnetic fields can control heat and sound

Sound waves are made of particles called phonons. New research shows they're affected by magnetic fields, with researchers able to steer heat magnetically.

Explainer: what is a superconductor?

Just what is a superconductor? And what can it be used for? Research using superconductors at higher temperatures opens up more possibilities for this fascinating class of materials.

Here’s a brainwave – magnetic pulses could treat autism

Around 1 in 68 children has an autism spectrum disorder (ASD), according to the US Centres for Disease Control – an extraordinarily high number. Although the prevalence rise is probably due mainly to changes…
