Hero Sniffer Rats

A man who teaches rats to sniff out land mines & tuberculosis - from Bart Weetjens:

Rats have more genetic material allocated to olfaction than any other mammal species. They are extremely sensitive to smell. Moreover, they have the mechanisms to map all these smells and to communicate about it.

Last year about 6,000 recorded people walked on live landmines .... worldwide almost 1.9 million died from tuberculosis as a first cause of infection.

TB can be diagnosed based by the volatiles exuding from patients.

The rats only need 200th of a second to discriminate the scents. (LA note: I want a Reality TV show - professional noses, rats, dogs, on your mark, get set, go!)

A microscopist can process 40 samples in a day, a rat can process the same amount of samples in 7 minutes only.*

Can you imagine the potential offspring applications, environmental detection of pollutants in soils, customs applications.... and so on.

- Bart Weetjens

Like any hero, simple - give it a food reward. Gentle.
