Nearly every country reporting COVID-19 deaths has identified a significantly higher mortality rate in males than in females. Why? Do sex hormones cause this disparity? Or do inherent differences in the immune systems of men and women render males more vulnerable? Biologist Adam Moeser of Michigan State University examines some of the factors that may be at play.
In other news, Isabel Hofmeyr and Charné Lavery introduce a collection of studies that explore the fascinating cultural, commercial and natural life of the Indian Ocean. They offer a new way of looking at world history, through a vast trading arena that served as the cradle of globalisation. And they invite us to look below the surface, at a largely unknown – but not unimagined – realm.
