An interview with myrmecologist Rüdiger Wehner from University of Zurich. Listen in as Dr. Biology learns how these desert animals are revealing their success in the Sahara Desert. Don't know what a myrmecologist is? This is a good show to find the answer.
Did you know the westerly winds in the Southern Ocean have been helping to keep our planet livable? Yes, they have been responsible for soaking up half of the human-made carbon dioxide (CO2) along with a whole lot of excess heat. Dr. Biology has the opportunity to talk with geoscientist …
The microbes that live inside us affect more about our lives than we might think. Taichi Suzuki is learning how these hitchhikers have been changing alongside humans.
