    ALPHA measures tiny energy gap in antimatter with improved precision

    Researchers at the ALPHA experiment have achieved a hundredfold improvement in their measurement of a feature of the antimatter counterpart of the hydrogen atom. The result, published today in Nature, allows a precise comparison of hydrogen and antihydrogen. In this study, the ALPHA Collaboration measured the ground-state hyperfine splitting of the antihydrogen atom, which comprises

  • G7 Evian 2026: travel and work recommendations at CERN

    As you may know, the G7 summit will take place in Evian from June 15 to 17, 2026. Given its immediate proximity to Switzerland, this event will have direct consequences on security, transport, and traffic in the Lake Geneva region, particularly in Geneva and along the main cross-border routes. Internal border controls with France will be

  • Ready for Heatwaves

    As spring gives way to summer, we must stay prepared for whatever the season brings – especially when it comes to periods of intense heat. MeteoSwiss declares a heatwave when average temperatures exceed 25°C for at least three consecutive days. To help protect personnel during such events, CERN introduced its dedicated Heatwave Action Plan in 2023. This

  • Before you sign anything: the NDA procedure is now on the Admin e-guide

    Exchange of confidential information is part of daily life at CERN. Whether you are exploring a new technology with a supplier, discussing sensitive commercial terms or preparing a collaboration, chances are someone will ask you to sign a non-disclosure agreement (NDA). And chances are, you will not be entirely sure what to do next. Good

    CERN summer students reunite 50 years later

    On 8 May 2026 a group of alumni of CERN’s Summer Student Programme reunited at the place where they first met 50 years ago. The group of four (left to right: Dave Eyre, Christian Gerke, Theo Oyevar and Claus Gössling) first came to CERN in 1976, when the Super Proton Synchrotron had just begun operating.

  • IMPACT undergoes a transformation: new interface launched for LS3 readiness

    Work to improve IMPACT, CERN’s Intervention Management Planning and Coordination Tool, has reached a major milestone. After several years of upgrade work and extensive user consultation, the “IMPACT declaration” (Activity feature) is now being launched to help support the needs of the CERN community during the third long shutdown (LS3). IMPACT is a critical web application used by a

  • Accelerator Report: From protons to ions – the LHC and its injectors prepare for the Run 3 finale

    Accelerator Report: From protons to ions – the LHC and its injectors prepare for the Run 3 finale

    At 6 a.m. on 19 May, the LHC Run 3 proton physics programme officially came to an end. Thanks to the excellent performance and availability of both the LHC and its injector chain, this year’s integrated luminosity surpassed all expectations, with all four main LHC experiments recording values well above the original projections (fig. 1).
