The universe is a cosmic web, woven from vast filaments that connect galaxies and clusters. Elena Pinetti explains how these elusive threadlike structures are opening a new window on the nature of dark matter. The post Welcome to the dark web appeared first on CERN Courier .

Radiopharmaceuticals based on novel radionuclides have, for the first time, reached blockbuster proportions. The post The age of the blockbuster-scale radiopharmaceutical appeared first on CERN Courier .

Laura Munteanu, Mathieu Perrin-Terrin and Stephen Dolan describe how neutrino tagging, proposed in 1979 and demonstrated at CERN, promises to tame the systematics limiting the next generation of neutrino-oscillation experiments. The post Neutrinos on the clock appeared first on CERN Courier .

Looking back on two terms as CERN Director-General, Fabiola Gianotti discusses some highlights of her tenure, the opening of CERN to private philanthropy and the case for science as a force for peace. The post Directing a decade appeared first on CERN Courier .

The European Strategy has recommended the FCC-ee as CERN’s next flagship collider. The case for it, Alain Blondel argues, rests on 50 years of inventions and discoveries. The post The FCC, half a century on appeared first on CERN Courier .

On 24 March 2026, the BASE collaboration sent 92 antiprotons on a test loop around CERN’s Meyrin site, achieving the first controlled and reversible transport of antimatter. The post Antimatter hits the road appeared first on CERN Courier .

The CMS collaboration reported an excess of top-antitop pairs in a new decay channel, consistent with the formation of a fleeting quasi-bound state. The post Two channels for the top–antitop excess appeared first on CERN Courier .

The 2026 Breakthrough Prize in Fundamental Physics recognised the multi-decade programme to measure, with ever-increasing precision, the muon’s anomalous magnetic moment. The post Breakthrough honours g–2 appeared first on CERN Courier .

On 6 February 2026, beams of oxygen ions circulated through the Relativistic Heavy Ion Collider at Brookhaven National Laboratory for the last time. The post Final collisions for the RHIC appeared first on CERN Courier .

Fewer than one in 10 billion charged kaons decay to a pion and a neutrino-antineutrino pair. NA62 has now measured this rate with 40% smaller uncertainty than before. The post The kaon stays on script appeared first on CERN Courier .

A deep survey with the Green Bank Telescope has now delivered a stringent non-detection of the expected pulsar population in the galactic centre, along with an intriguing millisecond pulsar candidate. The post On the hunt for cosmic clocks appeared first on CERN Courier .

The CMS collaboration has measured the branching fraction of a rare B s decay as a function of the dimuon invariant mass squared. The post A sharper probe of a rare B_s decay appeared first on CERN Courier .

The ALICE collaboration reported the first measurement of deuteron production in and out of jets in p–Pb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. The post Jets boost nuclear coalescence appeared first on CERN Courier .

The ATLAS collaboration reported the results of two new analyses that probe the CP properties of Higgs-boson interactions with electro­weak gauge bosons. The post Two new CP tests for Higgs couplings appeared first on CERN Courier .

The LHCb collaboration has announced its first Run 3 measurement of the CKM angle γ, a key parameter describing CP violation in the quark sector. The post An upgraded take on CP violation appeared first on CERN Courier .

The Electroweak session of the 60th Rencontres de Moriond gathered around 140 participants in the Alpine town of La Thuile, Italy, from 15 to 22 March. The post Rencontres de Moriond turns 60 appeared first on CERN Courier .

The 28th Chamonix Workshop took place from 2 to 5 February 2026, with around 130 participants from CERN and several international guests. The post Scaling new heights towards Long Shutdown 3 appeared first on CERN Courier .

The High Energy, Cosmology and Astro­particle Physics Abu Dhabi Workshop brought together more than 30 researchers to discuss some of the deepest mysteries in fundamental physics. The post Drilling down on dark matter appeared first on CERN Courier .

From 26 to 30 January 2026, the Max Planck Institute for Physics in Garching hosted the 9th FCC Physics Workshop, a major gathering of theorists and experimentalists working on the proposed Future Circular Collider. The post Garching gathers for the FCC appeared first on CERN Courier .

Held in Copenhagen on 22–23 October 2025, the RTI Summit brought together leaders from across Europe to shape the future of research and technology infrastructures. The post Big Science and industry meet in Copenhagen appeared first on CERN Courier .
