A combined team of researchers from the University of Copenhagen and the Swedish University of Agricultural Sciences reports that a certain fungus uses chemicals to trick male flies into mating with infected ...

In our October issue: Network representations of complex systems are limited to pairwise interactions, but real-world systems often involve higher-order interactions. A Perspective looks at the new physics emerging from attempts to characterize these int……
