"Could studying ants reveal clues to reducing highway traffic jams? Physicist Apoorva Nagar at the Indian Institute of Space Science and Technology thinks the answer is yes."

"Nagar says he got interested in the topic when he came across a study by German and Indian researchers showing that ants running along a path were able to maintain a steady speed even when there were a large number of ants on the path."

"Nagar says there are three main reasons ants don't jam up. Number one, ants don't have egos. They don't show off by zooming past people."

"The second thing is, they do not mind a few accidents, or collisions," say Nagar. So unless there's a serious pileup, they just keep going.
