The brains of Polistes paper wasps express different genes when identifying faces than when distinguishing between simple patterns, a study finds.

The forces of supply and demand appear influence paper wasp (Polistes dominula) populations. When more nest options are available, helper wasps work fewer hours to earn membership in a colony.

The insects’ insides provide a favorable environment for outcrossing in domestic and wild yeast strains, scientists show.
