The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
Nothing is harder to find than you might think.
Measuring the mass of W bosons took 10 years – and the result was not what physicists expected.

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.
The laws of physics explain why you can’t stop ink from spreading in water.
Probabilistic processes are never time-reversible.

The force of nature that holds the atomic nucleus together is poorly understood, but that may be about to change.
Cern scientists have successfully cooled antimatter with a laser for the first time.
Laser-cooling enables new measurements that could explain why antimatter is so scarce in our universe.
Dark matter can be inferred from an assortment of physical clues in the universe.
Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.
New mathematics have shown that lines of energy can be used to describe the universe.

Field theory describes the universe as energy flowing along unending lines. With this perspective, it is possible to define a new fundamental building block of matter.
Diligence, technological progress and a little luck have together solved a 20 year mystery of the cosmos.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
It would be fun to be able to shrink people and objects, but it’s something we can only imagine.

The movies make it seem like someday we’ll be able to make people and objects grow really big or shrink really small. Whether this will be possible comes down to the smallest of things.

One day we will have a science of consciousness, but it won’t be science as we know it today
Gravity helps stars to form.

Gravity exists because the universe is full of ‘stuff’ – here’s how it came to be.
Venus feels the sun’s heat – but how?

There are three ways heat can be shared: conduction, convection and radiation. Find out which one lets heat travel through space.
Is this it?
Everything you can touch is made of molecules – but feelings, sound and light are something different.
Map of all matter – most of which is invisible dark matter – between Earth and the edge of the observable universe.
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.
Things are kind of different on the quantum level.
Forget solid, liquid, gas. This research used advanced math to theorize about topological phases of matter. And over the years experiments with matter and cold atoms have been validating the ideas.
Machine to make anything.
The most powerful laser ever built could help us produce a machine that can turn energy into matter.
Cosmologists have detected a long sought component in the Cosmic Microwave Background (CMB), which will help us to further…
Researchers at the CERN Laboratory in Geneva have taken the first spectroscopic measurements of antihydrogen, marking an…
