I will review some new ideas that have made it possible to compute the first 3 loops amplitudes for non-trivial 2->2 scattering amplitudes at the LHC. As examples, I will illustrate new results for the production of pairs of photons in parton-parton annihilation and for four-quark scattering at three loops in QCD.
