A platoon of twitching noses

An interesting story from today's NY Times about the latest technique for detecting land mines: bq. Just about every method of detecting land mines has a drawback. Metal detectors cannot tell a mine from a tenpenny nail. Armored bulldozers work well only on level ground. Mine-sniffing dogs get bored, and if they make mistakes, they get blown up. bq. The Gambian giant pouched rat has a drawback, too: It has trouble getting down to work on Monday mornings. Other than that, it may be as good a mine detector as man or nature has yet devised. bq. Just after sunup on one dewy morning, on a football field-sized patch of earth in the Mozambican countryside, Frank Weetjens and his squad of 16 giant pouched rats are proving it. Outfitted in tiny harnesses and hitched to 10-yard clotheslines, their footlong tails whipping to and fro, the rats lope up and down the lines, whiskers twitching, noses tasting the air. And their sucess rate? bq. Indeed, in a test in November along a southern Mozambique railway that was heavily mined during this country's 17-year civil war, teams of three giant pouched rats found every one of 20 live mines in a previously unsurveyed 4,300-square-foot swatch of land. Very good idea... Posted by DaveH at May 18, 2004 11:09 AM
