How bombardier beetles bomb

For as long as researchers have been studying the bombardier beetle they have been baffled by their ability to produce an internal explosion in their abdomen and then expel a jet of boiling, irritating liquid towards their attackers while avoiding any physical damage. Now a team of researchers at MIT, the University of Arizona, and Brookhaven Laboratory have solved the conundrum.
