In the shadow of a misty mountain range in Tanzania, an elite special-forces unit of African giant pouched rats is training for a dangerous mission: ridding the world’s formerly war-torn regions of land mines.⠀
⠀
Their keen sense of smell allows these rats to sniff out explosives faster, and more reliably, than traditional minesweeping technology. In fact, the rats’ noses are so hypersensitive that they can detect tuberculosis in mucus samples more accurately than local lab tests, and ferret out criminals trying to smuggle endangered species like pangolins.⠀
⠀
According to Apopo, a nonprofit founded in Belgium that breeds and trains the rats, it could take a person with a metal detector up to four days to clear an area the size of a tennis court. In eastern Tanzania, Samia the rat (pictured eating a banana) clears the same ground in 30 minutes, and at 2 to 3 pounds in weight, rats like her are too light to set off a land mine. In 20 years, no rat has been killed in the line of duty, according to Apopo. The one downside: the rats are nocturnal and "weather sensitive," nearly refusing to work in the rain.⠀
⠀
Any day now, Apopo says Samia will be deployed to Angola, where a 27-year civil war that ended in 2002 left swaths of the country covered in mines. Some of her fellow recruits could be heading to Cambodia, Mozambique or Colombia.⠀
