Chimpanzees used in vaccine research get health checks in Liberia home - CTV News

A group of chimpanzees feeding together in a natural forest environment on Ngamba Island, Uganda. How likely is a chimpanzee (Pan troglodytes) to steal food from another chimp? It depends on whether they’re a friend or a foe. A team of biologists discovered that chimps pilfer less from their friends, and that the relationship between the victim and the thief influenced the emotional display of both parties.

European Medical Journal news storyPeople living with HIV may experience subtle changes in heart muscle function even when conventional measures of cardiac performance remain normal, according to findings from a systematic review and meta-analysis. Researchers identified significantly impaired global longitudinal strain (GLS) among people with HIV compared with HIV-uninfected individuals, despite preserved left ventricular ejection fraction (LVEF) in both groups. The findings suggest that speckle-tracking echocardiography (STE) could provide additional information about early myocardial dysfunction in this population. Read the full news story here.
