The VW Beetle might have started life as low-cost transport for the masses, but its modern reinvention has been all about style. The latest addition to the stable is no different, taking inspiration from modified "Baja Bugs" to create the rugged-looking Beetle Dune.
The bombardier beetle has a unique defensive mechanism. It induces a chemical explosion inside its shell to create a boiling, toxic liquid which it sprays at its aggressor. Now researchers in the US have discovered how it does this, and they hope that further study of the conditions inside the beetle that allow it to produce the jet without harming itself may inform real world technologies.
