User-friendly and interactive with smart recognition features, the new CERNature web application allows you to discover CERN’s rich floral biodiversity while contributing to growing its database

The LHC operations team and many other experts have been working hard to set up and validate the accelerator for safe beam operation, leading to the first stable beams for physics of 2025 on 5 May

Congratulations to everybody across CERN who was involved in the CERN70 communications campaign, which won the “In-house team of the year” award

It should be common knowledge among software developers that writing software with as few weaknesses, vulnerabilities and flaws as possible is the most cost-efficient solution

“Stable" particle beams are back in the LHC machine, marking the start of the 2025 physics data-taking campaign

The CERN-led educational programme Beamline for Schools is among the recipients of the 2025 awards of the European Physical Society’s High Energy and Particle Physics Division

CERN is committed to improving its energy performance. Having been one of the first scientific laboratories to obtain ISO 50001 certification for energy management, the Organization has now successfully passed its 2025 surveillance audit

The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature

An exhibition of old black-and-white photos at Geneva’s Bains des Pâquis retraces some of CERN’s history

The detection of longitudinally polarised W boson production at the Large Hadron Collider is an important step towards understanding how the primordial electroweak symmetry broke, giving rise to the masses of elementary particles
