Nelle cascate di sangue dell'Antartide antichi microrganismi marini

Researchers have identified ancient marine microorganisms within Antarctica's Blood Falls, a geological feature known for its distinctive red-colored brine. The study confirms that the water feeding these falls originates from the ocean, rather than being isolated from external environments as previously hypothesized.

This discovery provides new insights into the subglacial ecosystem of the Antarctic continent. By demonstrating a connection between the subterranean brine and the surrounding marine environment, the findings clarify the origins and biological composition of the water that sustains these unique microbial communities.
