As usual with pop science reporting, they fail to give a link to the actual paper. Here it is: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.11... And here is the preprint on arxiv.org, for those who don't have access to academia paywalls: https://arxiv.org/pdf/1612.04055.pdf TL/DR: The substance in question is a Bose-Einstein condensate, which is not an ordinary "fluid" and should not be expected to be have like one. This is simply one of the counterintuitive effects of quantum mechanics showing up in an experimental setting.
