The Buzz of Cities

BeeFor bees, bigger hives are better. 

Last week researchers at the University of Arizona published their findings: bees of bigger hives have more information and forage better. With improved communications, bees from the bigger hives sent new foragers to known resources up to four hours earlier than bees from smaller hives.1

This better communications also seems to work in bigger cities. Geoffrey West and the Santé Fe Institute provide impressive modeling on the scaling of cities. Double the size of a city and you get 1.15 times the growth of economy, patents and innovation. And as long as you can keep congestion and pollution in check, you can get this economic growth at only 0.85 times the cost of additional infrastructure. In other words, larger cities have a disproportionate impact on a country’s communications, and therefore a bigger impact on economy and culture.
