  • A recent study shows that neural symbolic regression offers a route to automated discovery of governing equations for network dynamics across high-dimensional complex systems.

  • The structure and dynamics of many social systems where human interactions involve communities can be described by higher-order networks. The authors propose a hypergraph-based model that describes how individuals form groups and navigate between groups of different sizes.

  • Networks with higher-order interactions provide better description of social and biological systems, however tools to analyze their function still need to be developed. The authors introduce here a decomposition of network in hyper-cores, that gives better understanding of spreading processes and can be applied to fingerprint real-world datasets.

  • We explore the world in search of novelties, which are traditionally defined as the first appearance of a new element in a sequence of exploration. The authors show that novelty can also arise from combining already known elements, introducing the concept of higher-order novelties as the first appearance of such combinations in the sequence. They propose a measure and model to study the dynamics of these higher-order novelties.

  • Pre-exposure prophylaxis (PrEP) is an effective HIV prevention measure but identifying those most at risk to target for treatment is challenging. Here, the authors demonstrate that non-selective PrEP distribution outperforms targeted strategies when use is not consistent, and/or prevalence of untreated HIV is high.

  • Social contagion cannot only be understood in terms of pairwise interactions among individuals. Here, the authors include higher-order social interactions, the effects of groups, in their model of social contagion, enabling insight into why critical masses are required to initiate social changes.

  • Network representations of complex systems are limited to pairwise interactions, but real-world systems often involve higher-order interactions. This Perspective looks at the new physics emerging from attempts to characterize these interactions.

  • Group interactions can dramatically alter social contagion dynamics and lead to the emergence of new phenomena like abrupt transitions and critical mass effects. The authors develop an approximate master equation framework to analytically describe contagion in heterogeneous hypergraphs and study the impact of large influential groups in seeding and sustaining epidemics.

  • Critical mass dynamics, where a minority of committed individuals reaching a critical size can overturn stable social conventions, is typically modelled by taking into account pairwise interactions only. Here, the authors generalise the Naming Game model to higher-order social interactions, and show both numerically and analytically how the interplay of local interactions and group size influences global social outcomes.
