Zombie ants

The pictures of zombie ants are gruesome enough for the M rating ("not before Meals"), but the report is encouraging. Ant colonies are defended against the parasitic brain-controlling fungus by a regime of thorough grooming and by another parasitic fungus in ants that attacks the brain-controlling one. "Because the hyperparasitic fungi prevents the infected zombie-ant fungus from spreading spores, fewer of the ants will become zombies."
