Huge Large Hadron Collider experiment gets 'heart transplant'
One of the Large Hadron Collider's huge experiments has been given what's described as a "heart transplant". Officials said the replacement of a key component inside the CMS experiment represented the first major upgrade to the LHC - the world's biggest machine. Engineers have been carefully installing the new "pixel tracker" in CMS in a complex and delicate procedure on Thursday 100m underground. Read more
Scientists are waiting for the first new data to start flowing from the underground particle smasher, as the LHC begins its first "physics collisions" in two years. Read more
A new record has been set by the Large Hadron Collider: its latest trials have smashed atoms with vastly more energy than ever before. On Wednesday night, two opposing beams of protons were steered into each other at the four collision points spaced around the LHC's tunnel. The energy of the collisions was 13 trillion electronvolts - dwarfing the eight trillion reached during the LHC's first run, which ended in early 2013. Read more
The Large Hadron Collider has smashed protons together for the first time since early 2013. The low-energy collisions, part of preparations for the next round of experiments, began on Tuesday morning. Proton beams circled the LHC and collided at an energy of 450 gigaelectronvolts (GeV) per beam. Read more
Restart of the Large Hadron Collider could lead to "new discoveries"
The restart of the Large Hadron Collider (LHC) could lead to "fundamental breakthroughs" in our understanding of the Universe, according to a Durham University expert. Read more
U.S. Scientists Celebrate the Restart of the Large Hadron Collider
Earlier today, the world's most powerful particle accelerator began its second act. After two years of upgrades and repairs, proton beams once again circulated around the Large Hadron Collider, located at the CERN laboratory near Geneva, Switzerland. Read more
LHC restart: 'Experimental' current blast fixes glitch
The short circuit delaying the restart of the Large Hadron Collider has been fixed, after a blast of high current melted the metal particle responsible. It is now likely that the LHC will see beams of protons racing around its 27km circumference early next week. Read more
As the Large Hadron Collider (LHC) gears up for its revamped second run, hurling particles together with more energy than ever before, physicists there are impatient. They want this next round of collisions to shake their discipline to its core. Read more
A senior researcher at the Large Hadron Collider says a new particle could be detected this year that is even more exciting than the Higgs boson. The accelerator is due to come back online in March after an upgrade that has given it a big boost in energy. Read more
