Graphene is a two-dimensional hexagonal lattice of carbon atoms. It has been realized experimentally a few years ago and is attracting considerable attention due to the quasi-relativistic nature of fermion excitations. I will describe recent work on the role of Coulomb interaction in graphene, where one encounters a new type of scale invariance in quantum field theories with Lorentz breaking. Ref: cond-mat/0701501
