This pattern of interactions matches how humans share information on social networking sites like Facebook, says the study's lead author, biologist Noa Pinter-Wollman. Most Facebook users are connected to a relatively small number of friends. A handful of users, however, have thousands of friends and act as information hubs.

computer simulations of the ants' social networks showed that information flows fastest when a small number of individuals act as information hubs. Fast-flowing information allows ant colonies to respond faster to threats such as predators and weather hazards, Pinter-Wollman says.

These well-connected ants might have an advantage in responding to threats, but they are also more vulnerable to infectious diseases, which can spread quickly through the colony.
