Cern has measure a tiny mass difference by colliding huge amounts of particles.
Record precision measurements at Cern may help explain why the universe has more matter than antimatter.
The muon experiment.
New particles or forces may exist that aren’t accounted for in the standard model.
Particle collisions are starting to reveal unexpected results.
If the finding really is the result of new fundamental particles then it will finally be the breakthrough that physicists have been yearning for for decades.
There’s a lot of matter in the universe, here the cat paw nebula of dust and gas.
New physics may be needed to explain why there’s more matter than antimatter in the universe.
The supernova remnant Cassiopeia A.
When scientists created the Higgs particle with protons, they needed the 10km-wide Large Hadron Collider. A muon machine could achieve it with a diameter of just 200 metres.
Is there anybody out there?
From the subatomic to the cosmic, don’t think for a second that we’re at the end of scientific history.
The Milky Way as seen from Yellowstone National Park.
A new experiment at CERN has discovered a source of asymmetry between matter and antimatter that could help explain why we are here at all.
Move over, Large Hadron Collider.
A new collider at CERN could push particle physics deep into an unexplored microscopic realm.
Scientists at Cern’s Large Hadron Collider have seen something that may force us to abandon everything we thought we knew about the world on the level of particles.
We hear a lot about the marvellous science going on at CERN. But what goes on behind the scenes?
There have been squabbles of course, but the science project in Geneva is an example of putting differences aside to pursue common goals.
Genomes don’t translate easily into an understanding of disease.
Big data is all well and good, but if we want medical breakthroughs, we’ll need big theory too.
There’s evidence that antimatter is produced in thunderstorms.
Antimatter is at the heart of one of the biggest conundrums in physics. Here’s why.
Running the world’s largest particle accelerator requires a lot of energy, but it could reveal the secrets of the universe.

The restart of experiments at CERN’s Large Hardron Collider could mark the start of a new era of discovery or a big disappointment.
Gearing up for another run.
CERN’s huge particle accelerator has been switched back on after a two-year upgrade to continue its search for answers.
Look into my high-energy particle physics and what do you see?
For less than the cost of a single Typhoon jetfighter, the upgraded LHC will push our understanding of physics to the brink.
The CERN datacentre is the ground zero, but only part, of a worldwide computing grid.
The ‘supercomputer’ that processes LHC’s data is a networked grid that spans the entire planet.
What lies within?
Ticking off subatomic particles one by one, now let’s see what an LHC upgrade will do.
Before the big bang.
SLAC National Accelerator Laboratory
Scientists working on an experiment at the SLAC National Accelerator Laboratory in the US have taken a step forward in developing a technology which could significantly reduce the size of particle accelerators…
