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

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

Positrons pass test for the Future Circular Collider
An experiment at the Paul Scherrer Institute (PSI) in Switzerland has successfully produced, captured and transported positrons using a novel system developed for CERN’s proposed Future Circular Collider (FCC). The results show that the key elements of the FCC positron-source concept can operate together, representing an important advance for this technically demanding aspect of the

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
