Sugar treat for bees creates a positive emotion state.

Scientists have discovered that when bumblebees drink a small droplet of really sweet sugar water, they behave like they are in a positive emotion-like state.The results published in the journal Science shows that after bumblebees drink a small droplet of really sweet sugar water, they behave like they are in a positive emotion-like state. Biologists at Queen Mary University of London (QMUL) findings suggest that insects have states that fit the criteria of emotions and open up new avenues for research into positive emotions in relatively simple nervous systems. The researchers trained bees to find food at a blue flower and no food at a green flower, and then tested the bees on a new blue-green flower. Bees that drank a small droplet of sugar water prior to the test took less time to land on the ambiguous-coloured flower. The other experiments showed that this behavior wasn't due to bees just getting more excited or searching faster. This indicates that the sweet sugar water may be causing a positive emotion-like state in bees, similar to humans and other animals.
