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…

A larger hadron collider? Why bigger is better in particle physics

While the world’s largest circular particle accelerator – the Large Hadron Collider (LHC) – will continue operation for the next few years, scientists have already started the conversation to build a much…

Physics: a fundamental force for future security

AUSTRALIA 2025: How will science address the challenges of the future? In collaboration with Australia’s chief scientist Ian Chubb, we’re asking how each science discipline will contribute to Australia…
Muons, a type of lepton, are studied at the Large Hadron Collider – but what are they? CERN

Explainer: what are leptons?

The giant Large Hadron Collider at CERN’s lab in Europe may be closed until 2015 but experiments will still be run there in the second half of this year on much smaller synchrotrons that examined the decay…

Dark matter experiment finds nothing, makes news

A US team with a highly sensitive dark matter detector has just finished its first run. It has found nothing, and that is still big news. Physicists can explain accurately the behaviour of what makes matter…

Explainer: what is proton therapy?

When you stand in the 27km-long Large Hadron Collider tunnel deep under Switzerland and France it looks as if the chain of blue magnets simply stretches off to infinity. So when people talk about putting…
At 31 kilometres long, the International Linear Collider is tipped to be one of the most exciting scientific instruments ever built. But why? ILC GDE

The International Linear Collider is coming – but why do we need it?

While the world’s most powerful particle accelerator - the Large Hadron Collider (LHC) - is on a two-year hiatus for repairs and upgrade, engineers are getting ready to construct the next generation of…
The Large Hadron Collider has temporarily shut down, but will return stronger than ever. CERN

Goodbye, for a while, to the Large Hadron Collider

The lord of the particle accelerator, CERN’s Large Hadron Collider (LHC), went out of particle collision business for almost two years as of late last week. For particle physicists, Valentine’s Day 2013…
