The science of social species goes under the microscope this week. We hear what radio-tagging individual ants is revealing about the way they organise their nests to decide who goes hunting and who stays at home. Meera explores the growth of urban apiculture, including why city-made honey tastes superior to its countryside equivalent, we find out how bees encountering hostility use a stop signal to deter their fellow foragers from befalling the same fate, and in Kitchen Science we explore the physics of flight to see how bees stay airborne. Plus why not cleaning your teeth could cause a heart attack, how early humans eschewed vegetarianism, mongooses that teach each other nut-cracking tricks and how to give a reef a coral transplant!
