Three physicists were arrested in so called "Novosibirsk case". It wasn’t the first time. Previously, four scientists were also accused of treason in different years. All of the scientists accused in all these cases participated in the projects of the seventh framework program of the European Union "TransHyBerian" (coordinator — Von Karman Institute of Hydrodynamics, Belgium). However, the interlocutors and sources of T-invariant suggest that the contacts of scientists with China and Iran are only an excuse, not the reason for the arrests.
