The buzz

Bumblebees bristle with anticipation when they approach a blossom. No, really! Researchers have discovered that flowering plants give off an electrical signal that tells bees their status and whether another bee has recently visited. Study leader Daniel Robert of the University of Bristol explains, "This novel communication channel reveals how flowers can potentially inform their pollinators about the honest status of their precious nectar and pollen reserves." The scientists are not exactly sure how the signal is understood, but believe the bumblebees' hair stands on end.
