Bees on Cocaine

My teenage son just told me about this 2008 experiment, so I looked it up:

In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate.

Normally, foraging honey bees alert their comrades to potential food sources only when they've found high quality nectar or pollen, and only when the hive is in need. They do this by performing a dance, called a "round" or "waggle" dance, on a specialized "dance floor" in the hive. The dance gives specific instructions that help the other bees find the food.

Foraging honey bees on cocaine are more likely to dance, regardless of the quality of the food they've found or the status of the hive, the authors of the study report.

That part is just funny; coked up bees get really excited. The next part is actually interesting science:

The findings, detailed this month in the Journal of Experimental Biology, shed new light on the famous honey bee dance language, said University of Illinois entomology and neuroscience professor Gene Robinson, who led the study. The research also supports the idea that in certain circumstances, honey bees, like humans, are motivated by feelings of reward.
