"Scientific American sixty seconds science. I'm Lucy Wong? Its peak cold and flu season, which means taking a lot of preventative measures frequent hand washing is a must as voiding co workers or friends who are sick. But we humans are not the only animal that changed behavior to keep diseases at bay so do ans- so the Frazier's and the nurses to different groups of work Natalie strumming of the university of Lucian. She and colleagues observed ans- to see their reaction to the presence of a pathogen. It's the nurses thing. Inside this taking care of brooch and being made of young workers to on the Frazier's all the 'cause that's outside of the nest to collect food and to defend the territory. Forger ants are at a greater risk of getting exposed to diseases because they leave the safety of the nest. So the researchers sprayed common fungus on a small group afford or aunts and then follow their movement. It's to see the way. The other ants reacted we marked Lance in. The colony was individuals labels which carries two inches buckled. Monks like QR coach, which is ultimately detected and recorded using a tracking system after the infection, the nurse and forger and stayed within their cliques and interacted less outside of their workgroup. The researchers also saw that forger and spent more time outside of the mess. They increase it to moan by fifteen percent. So by quite a large amount, three searchers awesome measure, the amount of fungus on each ant and saw that it was almost completely contained to the forgers group some nurse aunts. And even the Queen did have trace amounts of the fungus spores on them. But the amount was small enough that they could easily groom them off at their body. The study is in the journal science, not only does the cliqueish behavior. Stop the spread of the fungus. But it's an os. You did look in is Asian some. That's quite interesting in these. And that's been shown by other studies at when you receive very small amount of the sports. You don't have an increase in mortality risk because it's low enough that you can heal. So it's sort of boost your immune defences and protect you against later exposure to the same Jin seems that in their ability to avoid infecting other members of the community ans-, maybe more advanced than we are.
