I will discuss a recent construction wherein an effective de Sitter spacetime appears as a non-supersymmetric AdS decays to the supersymmetric vacuum. Four-dimensional observers are localized on a spherical brane which nucleates to facilitate the decay. The expansion of the brane bubble then leads to an effective four-dimensional de Sitter space. This construction side-steps the difficulties of constructing scale-separated de Sitter vacua in traditional flux compactifications. I will discuss new developments concerning four-dimensional phenomenology and the embedding of the scenario in string theory.
