Causal sets are an approach to quantum gravity in which the causal structure of spacetime plays a fundamental role. The nodes in this network are tiny quanta of spacetime, with two such quanta connected if they are causally related. Surprisingly, the structure of these networks in de Sitter spacetime, such as our accelerating universe, is remarkably similar to the structure of complex networks --the brain or the Internet, for example.

Metabolism is a fascinating cell machinery underlying life and disease. Here, we design a cartographic map of metabolic networks by embedding them into a simple geometry that provides a natural explanation for their observed network topology and that codifies node proximity as a measure of hidden structural similarities. Remarkably, we find an astonishing congruency between the architecture of E. coli and human cell metabolisms and the underlying geometry.
