Right from Slashdot:

The dangerous profession of anti-personnel mine detection is getting a surprising new tool: giant Gambian rats (NY Times reg). Some resourceful Belgians have figured out how to train these 30-inch rodents to hunt out landmines. They are cheaper and work harder than dogs and are more reliable than metal detectors. Plus, if one of them blows up, who’s going to cry?

Wolf or Loki might, you insensitive clod!
