Unusual professions of honey bees

We know everything about bees, it seems. They pollinate most of the plants we eat, as well as cotton, which is the basis of natural clothing fabrics. Yet the main product of these tireless workers is honey. Bees produce almost 1.2 million tons of honey annually.

Usually the worker bee dies after three weeks of work. During this time, she manages to fly 800 kilometers and visit almost a million flowers. As it turned out, amazing performance is far from their only advantage. Bees can count to four and are very trainable.

Over the past 15 years, scientists have developed a special technique, thanks to which bees have learned to identify more than 60 different odors. So they help to identify dangerous diseases in humans - cancer, tuberculosis, diabetes, find enriched uranium, crystalline methamphetamine and TNT - the main component of anti-personnel mines, from which tens of thousands of people are killed and injured every year around the world.

Bees detect dangerous diseases by smell

Biologists from France and Croatia have been successfully preparing sapper bees for several years now. The fact is that more than 120, 000 mines have not yet been cleared in the Balkans. The training takes only 2 days, after which the bees safely return to their native hive. A trained bee needs 10 minutes to find a mine with an efficiency of 98%. A similar indicator for a dog is 71%, while the cost of its training for 3 months is $ 9000. Plus, the bee will never blow up.
