  We apply novel techniques in planar superconformal Yang-Mills theory which
stress the role of the Yangian algebra. We compute the first two Casimirs of
the Yangian, which are identified with the first two local abelian Hamiltonians
with periodic boundary conditions, and show that they annihilate the chiral
primary states. We streamline the derivation of the R-matrix in a conventional
spin model, and extend this computation to the gauge theory. We comment on
higher-loop corrections and higher-loop integrability.
