A new fossil discovery indicates a second primate group also traversed the Atlantic millions of years ago on a raft of vegetation.

Rhesus macaques can be infected with SARS-CoV-2, leading primate center scientists to try to prevent outbreaks in their colonies, especially as experiments on coronavirus start.

A small study of macaques finds they don’t develop a coronavirus infection the second time they are exposed, supporting the idea of using plasma from recovered patients as a treatment for COVID-19.
