Ants Install Air-Conditioning

The huge underground nests built by grass cutter ants can house up to 7 million insects. To maintain a steady temperature the ants construct porous turrets to ventilate the nests. A team of scientists from Buenos Aires brought a colony of ants into the laboratory and provided them with three building materials: clay, coarse sand and fine sand. Looking at the constructions under the microscope they discovered that whatever materials they used, the turret walls were always highly porous, allowing air to flow through.
