  • While Digital contact tracing (DCT) has been argued to be a valuable complement to manual tracing in the containment of COVID-19, no empirical evidence of its effectiveness is available to date. Here, the authors report the results of a 4-week population-based controlled experiment, where they assessed the impact of the Spanish DCT app.

  • Studies of species interactions tend to focus on single ecological functions. Here, the authors show that plant species tend to participate across different ecological functions in a non-random, nested structure, and some species and functions emerge as unexpected keystone actors of the multifunctional ecosystem.

  • For most actors sustained productivity defines success. Here the authors study the careers of actors and identify a "rich-get-richer" mechanism with respect to productivity, the emergence of hot streaks and the presence of gender bias, and are able to predict whether the most productive year of an actor is yet to come.

  • Network memory impacts dynamical processes emerging in real-world social systems, however little is known about memory of temporal networks beyond pairwise interactions. The authors develop a framework to characterize the temporal organization of higher-order networks and propose a model of temporal hypergraphs with higher-order memory to reproduce the patterns emerging in real-world complex systems.

  • The evolution of networks with structure changing in time is dependent on their past states and relevant to diffusion and spreading processes. The authors show that temporal network’s memory is described by multidimensional patterns at a microscopic scale, and cannot be reduced to a scalar quantity.

  • Mediation analysis aims to clarify the nature of the relationship between two variables, by elucidating the role of a third variable, which can allow or suppress the relationship, or being simply not involved in the process. The authors introduce this framework in the analysis of three-layered multiplex networks, assessing whether a link between two nodes in one layer affects the probability of having a link between the two same nodes in the other two layers, and present some applications to social and biological networks.
