We've all heard of people who talk to their plants because they believe it will help them to grow, but now - thanks to a group of scientists in the USA - the plants may be able to talk back.
Engineers at the Massachusetts Institute of Technology (MIT) have created a system that uses spinach plants to detect explosive materials such as landmines. When these nanotechnology-enhanced plants notice a specific compound in the groundwater, the carbon nanotubes in the spinach leaves transmit a signal that is picked up by an infrared camera, which in turn sends an email alert to the scientists.
