Summary:

- The European Organization for Nuclear Research (CERN) has announced that it will sever its scientific ties with Russia, three years after Russia's invasion of Ukraine in 2022.
- This decision comes as a response to Russia's continued aggression in Ukraine and is part of the broader international effort to isolate Russia from the global scientific community.
- The move is expected to have significant implications for Russian scientists and researchers who have been collaborating with CERN, as they will no longer have access to the organization's facilities and resources.
