Podcast: Double navigation in desert ants, pollution in the brain, and dating deal breakers

Science Podcast
News stories on magnetic waste in the brain, the top deal breakers in online dating, and wolves that are willing to “risk it for the biscuit,” with David Grimm.   From the magazine How do we track where we are going and where we have been? Do you pay attention to your path? Look for landmarks? Leave a scent trail? The problem of navigation has been solved a number of different ways by animals. The desert-dwelling Cataglyphis ant was thought to rely on stride integration, basically counting their steps. But it turns out they have a separate method of keeping track of their whereabouts called “optic flow.” Matthias Wittlinger joins Sarah Crespi to talk about his work with these amazing creatures.   Read the research.   [Image: Rooobert Bayer /Music: Jeffrey Cook]
