The puzzle of neutrinos, seventy years on
Seventy years ago today, Clyde Cowan, Frederick Reines and their colleagues closed a quarter-century hunt with a paper in Science, having caught neutrinos streaming out of a nuclear reactor in South Carolina. The search had begun in December 1930, when Wolfgang Pauli, in a letter to the “radioactive ladies and gentlemen” gathered at a meeting

Efficiency meets environmental responsibility: commissioning CERN’s primary CO₂ cooling circuit
The ATLAS and CMS detectors require ultra-low, stable temperatures to protect their sensitive electronics. Traditional cooling systems rely on synthetic refrigerants like hydrofluorocarbons (HFCs), which, while effective, have a global warming potential thousands of times greater than CO₂. Seeking a sustainable alternative, CERN has turned to CO₂ itself – a natural refrigerant with a far

New spokesperson team for the LHCb Collaboration
On 1 July 2026, the management of the LHCb Collaboration changed. The new spokesperson team of Tim Gershon (Spokesperson, University of Warwick) and Paula Collins (Deputy Spokesperson, CERN) succeed Vincenzo Vagnoni (INFN Bologna), Patrick Robbe (IJCLab) and Ulrich Uwer (Heidelberg University). Tim and Paula will work together in the LHCb management with Eric Thomas (Technical

Heatwave alert: high fire risk across the CERN site
The current heatwave and dry conditions have significantly increased the risk of fire across the CERN site. Dry vegetation can ignite easily, threatening people, buildings and operations. Although a recent fire near the high-voltage substation on the Prévessin site was safely managed, it highlighted the potential danger. CERN’s Green Spaces team is taking measures to
