Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.
In both Drosophila and mosquitoes, protection lasts for generations following a single maternal exposure to positive-sense single-stranded RNA viruses.
In tissue samples from rhesus macaques, researchers find the virus in the same immune-privileged sites where Ebola has been found to persist in humans.
