Finding 'Beautiful' Symmetry Near Absolute Zero

This is a fairly good article on the recently discovered symmetry in a cobalt niobate compound. The article is rather lightweight on the actual work, and has more to do with explaining symmetry in a condensed matter system.

The actual work was published in Science this week[1].

Edit: You may read a review of this work at the PhysicsWorld website as well.
