    Analyses of COVID-19 infection rates show that non-pharmaceutical interventions achieved large, beneficial and measurable health outcomes in China, South Korea, Italy, Iran, France and the United States; these results may inform decisions on whether or when these interventions should be deployed, intensified or lifted.

    In human societies, individuals who violate social norms may be punished by third-party observers who have not been harmed by the violator; this study suggests that a reason why the observers are willing to punish is to be seen as more trustworthy by the community.

    Biodiversity threats from Red Lists are linked with patterns of international trade, identifying the ultimate instigators of the threats; developed countries tend to be net importers of implicated commodities, driving biodiversity decline in developing countries.

    Removing the protected status from poorly performing conservation areas, selling the land and using the money better elsewhere is controversial, but has a simplistic appeal. Here, it is shown that such degazetting can reap significant conservation benefits, even for the well-designed Australian network of protected areas, and even when there is a significant economic cost to transferring protected status to a new area.

    Social science hypotheses suggest that humans prefer more equality in outcome distributions because the knowledge of inequality reduces the reward experience. Here, functional MRI was used to test directly for inequality-averse social preferences in the brain during monetary transfers between pairs of participants and an experimenter. The results indicate that the brain's reward circuitry is sensitive to distribution inequality and is actively modulated relative to context.
