The paper compares left ventricular phenotypes across humans, chimpanzees, and macaques to identify structural and functional traits associated with higher stroke volume in humans.

The paper uses network analysis of 37 years of social association data in Soay sheep to show that social connections affect survival, with the importance of quantity versus quality depending on overwinter weather conditions.

The paper examines how group size and sex ratios affect injury risk in male and female rhesus macaques, finding sex-specific patterns linked to competition and aggression.

The paper examines how reduced social connectedness in older primates can mitigate infection risks from a hypothetical pathogen, showing age-related changes in social behavior affect disease dynamics.
