The search for dark matter: Axions have ever fewer places to hide
If they existed, axions -- one of the candidates for particles of the mysterious dark matter -- could interact with the matter forming our world, but they would have to do this to a much, much weaker extent than it has seemed up to now. New, rigorous constraints on the properties of axions have been imposed by an international team of scientists responsible for the nEDM experiment. (2018-02-14)
