Computer Security: Wipe no tears
Remember that feeling where your heart skips a beat? Or two? Or many? Where your breath gets caught in your throat? “Époustouflant” as the French say, but not in a good way? The moment when you can’t find your smartphone, even after looking everywhere? The moment on the tram when you recall that you didn’t

LHCb explores new territory during a special low-energy run
While the heavy-ion run season is in full swing at the LHC, let’s look back at the low-energy run that took place on 29 and 30 April. In yet another demonstration of the versatility of CERN’s accelerator complex, the LHC briefly departed from its standard high-energy operation to perform a special low-energy run dedicated primarily

Accelerator Report: An important upgrade to the PS radiofrequency system and a heavy ion run in full swing
In a particle accelerator, radiofrequency (RF) systems are among the crucial components that make beam production possible. While magnets guide the particles around the ring, RF systems provide the beam with its longitudinal structure: they accelerate it, keep it captured in bunches, shape it, split it, rotate it and ensure synchronisation for transfer to the

Students from Bangladesh, India, Türkiye, the UK and the USA win the 13th edition of Beamline for Schools
The winners of the 13th edition of the Beamline for Schools (BL4S) competition have been selected. BL4S is a physics competition that was initiated by CERN, the European Laboratory for Particle Physics, and is open to secondary school pupils from all around the world. Participants are invited to submit a proposal for a physics experiment to be undertaken

Getting under the skin of atomic nuclei using antimatter
Researchers at the AEgIS experiment have piloted a new method to delve into the heart of atoms. This proof-of-principle study, recently reported in Physical Review Research, shows how antiprotons – the antimatter counterparts of protons – could be used to probe the outer edges of a wider range of atomic nuclei. And with CERN’s recent

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

ATLAS observes new composite particle
Physicists from the ATLAS Collaboration reported the first observation of a new particle.

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.

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).

CERN: a haven for birds
CERN is not just a hub for groundbreaking research, it’s also a thriving sanctuary for biodiversity. Spanning 625 hectares, with 415 hectares of non-built environments, CERN’s sites host a remarkable variety of habitats, from forests and meadows to wetlands. These spaces provide a home to over 70 bird species, including the swift, woodpigeon, golden oriole,
