Inclusive fitness theory shows that social partners must be related for altruism to evolve, yet some models suggest that relatedness is not needed. An analysis concludes that assumptions in those models build in a role for relatedness, after all.

For those fortunate enough to have survived a deadly disease, a vital question remains: how long does their hard-earned immunity last? Tracking of antibodies in Ebola survivors reveals a surprising pattern.
