Between buzzes and body movements, they can direct hive mates to food sources, signal danger, and prepare for swarming - all indicators of colony health. And now, researchers are listening in. Scientists based in Germany - with collaborators in China and Norway - have developed a way to monitor the electrostatic signals that bees give off. Basically, their wax-covered bodies charge up with electrostatic energy due to friction when flying, similar to how rubbing your hair can make it stand on end. That energy then gets emitted during communications.

Band of brothers: Stallions can be kept together provided conditions are right - review

Share A group of stallions enjoying social contact on pasture. Photo: Agroscope, Schweizer Nationalgestüt, Switzerland https://doi.org/10.3390/ani11051317 Many stallions lead largely solitary lives, but it need not be that way, the authors of a just-published review have concluded. Researchers with the Free University of Berlin concluded that many stallions could be kept safely in groups, provided key conditions are met. “It only poses a risk for injuries if the necessary requirements for this type of husbandry are not taken into account,” Heidrun Gehlen, Katrin Krumbach and Christa Thöne-Reineke wrote in the open-access journal Animals. Crucial elements for safety include the absence of mares, a suitably sized area or pasture that provides good escape routes, suitable groupings that take into account the character of the stallions, multiple feeding and drinking places, as well as suitable lying and resting areas.
