A new layer of silicon sensors is being tested at CERN before being sent to the International Space Station

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…

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 […]

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 […]

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 […]

On 1 August 2026, the CERN Community Support Centre (CCSC) in Building 33 celebrated its second anniversary. The Centre plays a key role in onboarding newcomers; in June 2026 alone it welcomed around 6900 new arrivals. Working closely with services across the Organization, the team provides efficient first-line support to CERN personnel every day. Congratulations to […]

Jens Bisplinghoff (1944 – 2026) — The AMBER Collaboration is deeply saddened by the passing of our dear colleague Jens Bisplinghoff at the age of 81. Jens devoted more than four decades to experimental nuclear and particle physics. He began his scientific career in nuclear physics, conducting research at the University of Bonn, the Nuclear […]

On 22 July 2026, the ALICE Collaboration honoured the winners of its PhD Thesis Award during a special ceremony held as part of its meeting at CERN. The ALICE PhD Thesis Award is dedicated to the memory of Karel Šafařík (1953–2024). Since 2008, ALICE has recognised the most outstanding PhD theses based on the excellence of […]

Niobium-94, an isotope of niobium with 41 protons and 53 neutrons, is a critical crossroads in the complex nuclear processes that forge heavy elements under the intense pressures and temperatures of dying stars. Writing in Physical Review Letters, the n_TOF Collaboration reports the first ever measurement of the probability of niobium-94 taking one of the […]

The Site Operations Sector is running a Facility Managers pilot project to improve the working environment in selected CERN buildings. The pilot introduces two dedicated Facility Managers to serve as local points of contact for people working in and using the buildings. By being regularly on site and proactively monitoring facilities, they help improve safety […]

Due to works, Entrance A will be closed to vehicles on Thursday, 20 August and Friday, 21 August 2026. Drivers are invited to use other entrances to access the Meyrin site during this period. Access for pedestrians and cyclists will remain available. For gate opening hours and the latest campus notices, download the CERN Campus App. 

Preparatory works for the future Building 140 will begin on 17 August 2026 and are scheduled to continue until 18 December 2026. This initial phase includes the diversion of existing utility networks and the installation of new networks required to serve the future building. To keep traffic flowing throughout this phase, Route Bakker will first be temporarily […]

From 10 to 12 July 2026, CERN and the Open Quantum Institute (OQI) hosted the second edition of the Quantum Materials Hackathon, which brought together 34 students of over 30 nationalities. The students used quantum computing hardware and simulators to tackle real-world problems, guided by mentors from industry and the research community. Quantum materials are particularly important at CERN, as […
