Risky business: linking _Toxoplasma gondii_ infection and entrepreneurship behaviours across individuals and countries | Proceedings of the Royal Society B: Biological Sciences
Using a saliva-based assay, we found that students (n = 1495) who tested IgG positive for Toxoplasma gondii exposure were 1.4× more likely to major in business and 1.7× more likely to have an emphasis in ‘management and entrepreneurship' over other business-related emphases. Among professionals attending entrepreneurship events, T. gondii-positive individuals were 1.8× more likely to have started their own business compared with other attendees (n = 197). Finally, after synthesizing and combining country-level databases on T. gondii infection from the past 25 years with the Global Entrepreneurship Monitor of entrepreneurial activity, we found that infection prevalence was a consistent, positive predictor of entrepreneurial activity and intentions at the national scale, regardless of whether previously identified economic covariates were included. Nations with higher infection also had a lower fraction of respondents citing ‘fear of failure' in inhibiting new business ventures. While correlational, these results highlight the linkage between parasitic infection and complex human behaviours, including those relevant to business, entrepreneurship and economic productivity.

Infected ‘Zombie Spiders’ Forced to Build Incubation Chambers for Their Parasitic Overlords
Parasites that control the behavior of their hosts for their own benefit are a well-documented natural phenomenon, but the discovery of a previously unknown relationship between a parasitic wasp and a social spider is particularly upsetting.
