Bee brains reveal how colonies divide work without central planning

What determines which tasks bees perform in their colony? Biologists from Heinrich Heine University Düsseldorf (HHU) and the universities in Cologne and Frankfurt/Main have investigated the role neural activity plays in this process. In an article published in the Proceedings of the National Academy of Sciences, they explain that by manipulating a specific gene, they can selectively inhibit neural circuits in bees and thus influence their work behavior.
