Measuring the mass of W bosons took 10 years – and the result was not what physicists expected. PM Images/Digital Vision via Getty Images

A decade of science and trillions of collisions show the W boson is more massive than expected – a physicist on the team explains what it means for the Standard Model

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.

2021: a year physicists asked, ‘What lies beyond the Standard Model?’

Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?

Want disruptive research? Go small instead of big

A new study in Nature finds that large research teams develop recent ideas, while small teams conduct more disruptive and innovative research.

Ten years of Large Hadron Collider discoveries are just the start of decoding the universe

The Large Hadron Collider has generated mind-blowing science in the last decade – including the Higgs boson particle. Why is the LHC so important, and how will physicists use it in the years to come?
There’s a lot we still don’t know about antimatter. Shutterstock

Antimatter breakthrough sheds light on matter’s shadowy twin

One of the great mysteries of the universe is why there is so much more matter than antimatter. Now a new experiment is helping us understand the nature of antimatter better than ever before.

The big data challenge and how Africa can benefit

Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.

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?
