“Kovalchuk proposes that our scientists become a dish on the table of an ogre.” Why Russia has failed to maintain relations with CERN

on 30 November 2024, the five-year agreement between the European Organisation for Nuclear Research (CERN) and the Russian Federation will end. T-invariant recalls how dramatically CERN and Russia have severed their relations over the past years and publishes an interview with a witness to these events - scientist Andrei Seriakov from St Petersburg.

Non-free laser on free electrons. How scientists from Russia lost the opportunity to work on a unique facility?

As of 30 November, Russian scientists will no longer have access to the facilities of the European Organisation for Nuclear Research. This is not the only scientific instrument to which access has been closed due to Russia's invasion of Ukraine. T-invariant takes the example of the European XFEL free electron laser to understand what this means for science and what scientists who have lost access to this state-of-the-art research method are doing.
