An anonymous reader writes "Results indicate floral electric fields improve the bees' ability to discriminate between different flowers. When used with visual signals, electrical cues can enhance the bee's memory of floral rewards. Researchers suggest this method of signalling provides rapid and dynamic communication between plants and pollinators..."What the pollen needs to 'know' is when to 'jump' onto the 'vehicle' — the bee — and when to get off it. So it's a selective adhesion type of question," Prof Robert told BBC Nature."
