Microbes That Travel Through the Sky: 'Invisible Life' Drifting in the Atmosphere Over Long Distances

Key points (reviewing AI explanation)
Countless microbes drift even in the air we breathe. What's surprising is that they can become 'seeds for clouds.' For water vapor to become water droplets, it needs a nucleus in the form of tiny particles, and when microbes play that role, it means living organisms are involved in the weather. This theme, where biology, earth science, and meteorology mix together, forces a shift in thinking: 'ecosystems are not confined to the ground.' What would you see if you looked at the familiar air around you under a microscope? It's also an interesting angle for an inquiry-based research topic.
Explanation
It has become clear that invisible microbes travel thousands of kilometers through the atmosphere on the wind. The June issue of Nikkei Science also covered 'the long-distance flight of microbes,' discussing the possibility that bacteria and fungi lifted into the air along with dust and sea spray can become the nuclei of clouds, triggering rainfall, or affect distant ecosystems. The perspective here is that the sky is not merely a layer of air but also a 'road' along which life travels.
