Evidence for early life in Earth's oldest hydrothermal vent precipitates
Although it is not known when or where life on Earth began, some of the earliest habitable
environments may have been submarine-hydrothermal vents. Here we describe putative …

Exceptional Preservation of Fungi as H2-Bearing Fluid Inclusions in an Early Quaternary Paleo-Hydrothermal System at Cape Vani, Milos, Greece
The production of H2 in hydrothermal systems and subsurface settings is almost exclusively
assumed a result of abiotic processes, particularly serpentinization of ultramafic rocks. The …
