Landmines, improvised explosive devices (IEDs), and other homemade bombs struck 6,461 people worldwide in 2015, killing at least 1,672. Survivors are often left with devastating injuries. In a study published in BMJ Open, 70 percent of people hit by IEDS in Afghanistan required multiple amputations. These homemade bombs are often hidden—nestled in bushes, buried underground, or sometimes stuffed inside other objects. To keep soldiers away from these deadly weapons, researchers are developing technology that can spot explosive hazards precisely and from a safe distance.
