MAPUTO, Mozambique, Nov. 23 (UPI) -- Rats in Africa have been trained to use their sensitive noses for the benefit of humans by sniffing out land mines and diagnosing tuberculosis.
The rats involved in finding land mines in Mozambique have been bred to be the size of raccoons, The Boston Globe reports. While the squads of mine-sniffing rats were mocked at first, officials are considering using them in the Democratic Republic of Congo, Zambia and other countries where unexploded mines remain common.
