In this talk, I will discuss new results deduced from the simple statement that scattering amplitudes must satisfy consistent factorization conditions. This includes non-renormalization theorems for an infinite number of higher dimension operators with maximal supersymmetry, and the existence of new soft theorems for fermions in supergravity, similar to that of scalers which are goldstone bosons.
