All the magnets we’ve ever seen have a north and a south, but there might be some out there that have only one end. Shutterstock

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.

Explainer: what is mass?

We talk about mass all the time but what is it that actually gives an object mass? And why do some things have mass and others have no mass at all?

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 are fundamental particles?

Subatomic particles have shaped and continue to shape our universe but despite perfect predictions by physicists, the theory about unseen particles is still wrong.
Look into my high-energy particle physics and what do you see? CERN

Upgraded LHC pushes physics into the unknown

For less than the cost of a single Typhoon jetfighter, the upgraded LHC will push our understanding of physics to the brink.

The LHC is back and it’s ready to probe the limits of matter

The Large Hadron Collider is ramping up to probe even deeper into the fundamental constituents of matter.
And then it falls apart, a bit like this. brookhavenlab

Quirky quark combination creates exotic new particle

Since the spectacular discovery of the Higgs boson in 2012, physicists at the Large Hadron Collider (LHC), the gigantic particle accelerator outside Geneva, have suffered a bit of a drought when it comes…
