Familiarity 85Skin microbiome
A site-specific living film — oily, moist and dry neighbourhoods, not a sterile wrapper.

The hidden workforce of land — decomposers, mycorrhizae and a mostly uncultured majority.
Familiarity 48Nitrogen cycle
How microbes move nitrogen between air, soil, water and food — plus the industrial shortcut that feeds billions.
