Bienen gegen Minen

Was diesen Amerikanern so einfällt ist manchmal schon verwunderlich. Sie benutzen Hühner als Chemiewaffendetektoren, Delphine finden Minen im Meer und sie setzen im Irak natürlich auch Hunde ein, die sogar Schutzwesten tragen. Nun will die US Army auch Bienen zum Aufspühren von Landminen einsetzen. Jedenfals trainiert die militärische Forschungseinrichtung DARPA (jo, von denen kam mal das Internet) Bienen zu diesem Zweck.

Bees… can be trained in a couple of days to pick up the scent of the explosive in the landmine… When released into a minefield, the bees find their way toward the mines… [They] are too small to detect either with the naked eye or high-resolution video at long ranges. So instead, the team employs a laser emitter that sweeps an area like radar or sonar. When the light hits a bee, it reflects, and sensors are able to tell by the reflection just where the bee is. After sweeping several times, the scientists are able to crunch the data and see statistically where the higher occurrences of bees are located.
In controlled situations, the method is extremely effective: Bees can detect very small traces of explosive vapors with 97% accuracy and are “wrong” — that is, passing over a mine without noticing it — less than 1% of the time.

Und was kommt als nächstes? Das Sprengschaf oder das Kamikazee-Kamel?
