  • Examination of previous results and computational analysis of empirical data sets representing mutualistic plant–pollinator networks shows that a simple metric—the number of mutualistic partners a species has—is a better predictor of individual species survival (and hence, community persistence) than is the nestedness of ecological networks.

  • Dimethyl fumarate (DMF) is an anti-inflammatory drug proposed as a treatment for COVID19. Here the results are reported from a randomised trial testing DMF treatment in 713 patients hospitalised with COVID-19. DMF was not associated with any improvement in day 5 outcomes.

  • What is the best way for predators to find food when prey is sparse and distributed unpredictably? Theory predicts that in such circumstances predators should adopt a Lé-flight strategy, in which short exploratory hops are occasionally interspersed with longer trips. When prey is abundant, simple Brownian motion should suffice. Now, analysis of a large data set of marine predators establishes that animals do indeed adopt Lévy-flight foraging when prey is sparse, and Brownian episodes when prey is abundant.
