Abstract
Microbiological research must now bridge the gap between descriptive and correlative ecology—derived from metagenomics—and functional biology capable of elucidating its mechanisms. This is a Herculean task, given the vast chasm that remains between laboratory models and the complexity of natural environments. We must learn to move from homogeneous conditions to heterogeneous environments, and from interactions between two partners to entire ecosystems. The methodological toolkit is vast: structural biology, genetics, imaging, microfluidics, computational biology, and artificial intelligence. But this complexity cannot remain the exclusive domain of researchers. It must be shared with citizens and policymakers, particularly through education and citizen science. The challenge is as much scientific as it is democratic: to make this “dark matter” of life visible, to understand how it makes the planet function, and to collectively decide how we want to act upon it.
