Nature News: The Dutch government has enacted legislation barring Iranian nationals from access to courses and facilities related to nuclear technology.

Under the new law, passed on 4 July, Iranians, including those holding dual citizenship in the Netherlands, will be unable to enrol in graduate-level courses involving nuclear and rocket technologies. These encompass nine subject areas outlined in the legislation, including the technology of reactors for uranium enrichment and the chemistry of rocket fuels. Some students will be allowed to take these courses with a special government waiver, according to Rob Dekker, a spokesman for the Dutch foreign ministry.
