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.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles.

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?

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

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?
How does our world work on a subatomic level?

A particle physicist explains just what this keystone theory includes. After 50 years, it’s the best we’ve got to answer what everything in the universe is made of and how it all holds together.

Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
There’s a lot we still don’t know about antimatter.

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.
Genomes don’t translate easily into an understanding of disease.

Particle accelerators are helping to push forward the frontiers of theoretical physics but they’ve also had more impact on your everyday life than you realise.
The Large Hadron Collider is playing a key role in enabling the collection of big data.

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.
You can feel the weight of an object on Earth because of its mass. But 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?
