I will discuss a recent Theorem on Hausdorff content that I have been working on. It is somewhat surprising that this lemma gives a new proof of the de Giorgi characterization of finite perimeter sets, but is also strong enough to deduce the mass transference principle. The work is ongoing, but I will present the new estimate on Hausdorff content, some of the tools and some of the applications I have and will apply this estimate to.
