CERN to expel hundreds of Russian scientists
The researchers will lose their access to CERN, which operates the largest particle physics laboratory in the world, by December.

CERN, the European particle-physics collaboration that operates the Large Hadron Collider, will expel hundreds of Russian-affiliated scientists from its laboratories.
The Geneva-based organization decided to cut ties with Moscow after Russia’s 2022 invasion of Ukraine, ending nearly 60 years of collaboration, and the agreements are now lapsing. Russia has never been a full member but worked closely on nuclear physics.
Scientists tied to Belarusian institutions already saw their contracts end in July, and any Russian-linked scientists will lose access, as well as residency permits, in December.
CERN will, however, maintain links with the Joint Institute for Nuclear Research, an intergovernmental center near Moscow, a decision that is controversial for some researchers.
