Scientists studying ants pour over 10 tons of concrete into their colony to study its structure. The complexity of what they dug up was truly astounding:
The structure covers 538 square feet and travels 26 feet into the earth. In it’s construction, the colony moved 40 tons of soil. Billions of ant loads of soil were brought to the surface. Each load weighed four times as much as the worker ant, and in human terms, was carried over 1/2 mile to the surface.

P.S. -- I looks like the Saudi's are trying to imitate:
First Dubai. Now this. Flush with petrodollars, Saudi Arabia is building itself shiny new cities, according to this story in the New York Times. But who will live there: Is this really the kind of place than can attract global talent? Call me cynical but these new Middle Eastern places remind me less of propulsive cities and much more of monuments to materialism. Built on the rents from resources, they are essentially the contemporary "castles" of 21 century capitalism.
