There was another article about this group's work back in September, at http://www.nature.com/news/quantum-uncertainty-not-all-in-the-measurement-1.11394-- it seems as though this is not really about contradicting the mathematical form of uncertainty in the equations of quantum mechanics, but rather about certain interpretations of uncertainty which say it's all induced by measurement. As Steinberg says in that article:
'Don't get too excited: the uncertainty principle still stands, says Steinberg: “In the end, there's no way you can know [both quantum states] accurately at the same time.” But the experiment shows that the act of measurement isn't always what causes the uncertainty. “If there's already a lot of uncertainty in the system, then there doesn't need to be any noise from the measurement at all,” he says.' Also see the abstract of a paper by Rozema et al (the main scientist they quoted in Dan's link) at http://physics.aps.org/synopsis-for/10.1103/PhysRevLett.109.100404 which says: "When first taking quantum mechanics courses, students learn about Heisenberg’s uncertainty principle, which is often presented as a statement about the intrinsic uncertainty that a quantum system must possess. Yet Heisenberg originally formulated his principle in terms of the “observer effect”: a relationship between the precision of a measurement and the disturbance it creates, as when a photon measures an electron’s position. Although the former version is rigorously proven, the latter is less general and—as recently shown—mathematically incorrect."
