Soft and collinear singularities plague the calculation of scattering amplitudes in massless gauge theories. Currently when calculating infrared safe physical observables these singularities, which appear in the individual amplitudes which contribute, can be shown to cancel amongst themselves. This method of calculation though is not ideal, handling such singularities analytically is a large bottleneck for the calculation of higher order amplitudes. I will discuss new techniques for deriving scattering amplitudes which are completely free of infrared singularities and hence could sidestep this bottleneck. I will then discuss the potential application of these new types of amplitudes to the calculation of physical observables.
