Non-singular black hole geometries typically come with two spacetime horizons: an (outer) event horizon and (inner) Cauchy horizon. This nurtures the speculation that they may be subject to a mass-inflation effect which renders unstable. We analyze dynamics associated spherically symmetric, regular holes taking full backreaction between infalling matter geometry into account. On this basis, we ...

Party finance allows elucidating parties’ behaviour in differing political and institutional contexts, yet only a few studies investigate expenditure patterns. Given that campaign activities are central for parties to fulfil their core functions representative democracy, this study seeks explain why invest electoral campaigns different degrees. We argue high party fragmentation reinforces focus...

Maturation of GABA inhibitory circuitry in primary visual cortex activates the critical period of plasticity, but the underlying mechanisms are not well understood. In the August 8th issue of Cell, Sugiyama et al. demonstrate that visual experience promotes the passage of a retina-derived homeoprotein along the visual pathway, which nurtures subclasses of cortical interneurons implicated in reg...

In recent years, new ways of visualizing data and networks have had an enormous influence on many areas of research, allowing, for example, thousands of data points to depict clear trends in science citations or genomic patterns. But the impact of these methods has extended beyond areas of scientific inquiry: their aesthetic has also caught the attention of artists, whose work is characterized ...
