I will discuss bounded cohomology, as well as CAT(0) cube complexes. In joint work with T. Fernos and A. Iozzi, we prove the non-vanishing of the second bounded cohomology of a group with a non-elementary action on a CAT(0) cube complex, and we apply this result to establish a super-rigidity result.
