Spinach: Now a Bomb-Detecting Superfood

To detect explosive compounds, researchers have designed plants that communicate with us.

Scientists from MIT added carbon nanotubes to spinach plant leaves, which causes the plants to emit infrared light when compounds called nitroaromatics, often used in explosives, are in the water. A specialized camera then reads the fluorescence from the plant, which signals a positive match, and an email is sent via a Raspberry Pi computer. Researchers believe their augmented plants represent early
