There are places on the planet, such as the frozen caverns of ice located hundreds of meters deep inside the earth, where it seems impossible that there are living beings. However, the biologist and caver Hazel Barton has discovered in a cave in Kentucky 100 new species of unknown microbes, 24 of which had antibiotic properties, which was the object of her research.
Scientific hunting of the microbe in underground ecosystems has led to another incredible discovery: these tiny beings modify the chemical composition and, with it, the shape and color of the rock, since they obtain nutrients from iron, manganese, nitrogen and sulfur from the stones, and they come to stain them blue, purple or white when they metabolize these elements.
