Dozens of times over the eons, rove beetles have made complex, independent adaptations to live inside the nests of ants — the phenomenon of convergent evolution. Biologists want to know if this shows patterns at work in natural selection.
The body’s defenses lose flexibility and diversity over time, and protective responses to vaccines weaken as well. Scientists are working on ways to boost seniors’ protections against influenza, the novel coronavirus and other pathogens.
