Bacteria run Earth's engines unseen, steering climates, soils, and health.
Bacteria communicate with fungi via shared chemical signals, coordinating nutrient floods across ecosystems without a nervous system.
Nearly every measurable gas in Earth's atmosphere is produced or consumed by bacteria, dwarfing human-industrial influence in some cycles.
Some bacteria survive space-like conditions by forming spores that outlast years of cosmic radiation and vacuum exposure.
Bacteria inside our gut outnumber human cells by order of magnitude, effectively making us a hyper-dense microbial city.
