Waste management during LS3: we all have a role to play
Long Shutdown periods generate large volumes of waste across CERN sites. During Long Shutdown 3 (LS3), maintaining good waste management practices is particularly important to ensure safety and minimise environmental impacts and costs. As part of its environmental and sustainable development strategy, CERN has set environmental objectives for 2030, including specific targets related to waste

Computer Security: Hot Review Summer, Cool Deployment Autumn
This summer has seen a plethora of different assessments of the Organization’s security posture and stance. While an external vulnerability scan of CERN’s Internet presence and a red-teaming penetration test are still ongoing, the Computer Security Office, in collaboration with the IT Department, is continuing to mitigate the findings of the 2023 cybersecurity audit, the

All CERN accelerators now on the road to HiLumi
CERN’s injector complex and Antimatter Factory took their final steps towards Long Shutdown 3 (LS3) this morning, as the last particle beams were extracted and the machines fell silent. This milestone follows the shutdown of the Large Hadron Collider (LHC) in June, which marked the beginning of LS3 for the Laboratory’s flagship accelerator. While the

Improving the CERN Meyrin site: ongoing works and how to get around
As many members of the CERN community return from the summer break, a number of infrastructure projects are under way across the sites. While these works may temporarily affect traffic, parking and access, they form part of a broader effort to develop and improve CERN’s campuses. The projects highlighted below are among the major infrastructure works currently

ATLAS and CMS narrow in on double-Higgs production
Finding one Higgs boson was hard enough, but physicists at the Large Hadron Collider (LHC) are hunting for something even more elusive: pairs of Higgs bosons. At the recent International Conference on High Energy Physics 2026, the ATLAS and CMS Collaborations presented new constraints on the double-Higgs production rate, providing insight into how the Higgs

Final tests for the AMS upgrade before spaceflight
A new layer of silicon sensors is being tested at CERN before being sent to the International Space Station

Help find CERN’s missing history
The CERN Heritage Collection holds over 350 objects that help tell the story of CERN’s scientific and technical achievements. Many of these objects go on display in the Science Gateway and are loaned to museums all over the world. For some of these objects, key information is missing: what they were used for, who used them, when and why. In other cases, an object’s

Accelerator Report: Final countdown – CERN’s injector complex enters its last stretch before LS3
The LHC has already fallen silent for Long Shutdown 3 (LS3), but elsewhere across CERN’s accelerator complex the pace remains intense. With just a week and a half of beam operation remaining, the countdown has begun for all the machines, which will switch off their beams at 6.00 a.m. on Monday, 31 August, marking the

Celebrating John Ellis’s enduring legacy
On 31 July, colleagues and friends of theoretical physicist John Ellis came together to celebrate his 80th birthday and almost 60 years of service to CERN and the wider particle physics community. “Many of us were amazed to learn of John’s significant impact on fields besides our own,” said physicist Matthew McCullough, Deputy Head of

Computer Security: AI – Game over, mankind?
With the more and more prevalent use of agentic AI, i.e. programmed agents acting and working on our behalf, and in a fully interconnected world, i.e. us living in symbiosis with the Internet, smartphones and control systems, how far-fetched is it that humans can actually become a threat to an AI system such that it
