Cian O'Luanaigh was the web editor in the CERN communications group from 2011-2015.
The Large Hadron Collider today collided protons at lower energies than usual to pave the way for studying lead-ion collisions
After some 400 trillion proton-proton collisions delivered to both ATLAS and CMS, the accelerator will now switch to its heavy-ion programme
At the United Nations in Geneva yesterday, CERN representatives discussed their laboratory’s model for international cooperation and science for peace
Dedicated teams of professionals and nature enthusiasts alike are working to preserve the flora and fauna on CERN's diverse sites
During this week's planned technical stop, engineers modify the electrical system that protects magnet components from high current
The LHC Operations team is tackling the challenges of a demanding beam regime with a series of rigorous tests
Untangle a rare particle decay from the background in LHCb data and you could win up to $7000
Check out a new podcast from particle physicists Tova Holmes and Laura Jeanty that brings you right to the heart of the ATLAS collaboration
From cloud chambers to 3D animations, physicists use a host of ingenious techniques to reveal subatomic particles too tiny to see
The MOEDAL, TOTEM and LHCf experiments are preparing to collect data from collisions in the LHC at 13 teraelectronvolts
Last night, for the first time, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV. See the first images
These first collisions at 13 TeV in the LHC are to set up systems that protect detectors from stray particles before they are fully switched on
