1973
“In 1973 Karl von Frisch won the Nobel prize for a series of studies done in the 1940’s on the navigational ability of the honeybee. He found that they utilized both a sun angle compass and a polarized light system for navigation. Perhaps more amazing was their ability to communicate the vector and distance of a food source to other workers in the hive by means of a “dance” that used both the sun angle and the gravitational vector. While the sun angle and polarized light were quite efficient they would be absent on cloudy days. However, the bees were still able to navigate with the same precision under those conditions. There obviously had to be a back-up system of some kind available to these animals that was totally independent of these two cues.”

“In 1974, the Russian researchers Eskov and Sapozhnikov found that bees generate electromagnetic signals with a modulation frequency between 180 and 250 Hz when they do their communications dances.
