Physiological Trade-offs Drive The archaeal Dominance And Carbon Turnover In Deep Subsurface
Marine sediments host a vast deep biosphere, yet how microorganisms persist under severe energy limitation and govern long-term organic carbon (OC) preservation remains poorly understood.

A Thousand Meters Deep: Vertical Profiling of the Subterranean Microbiome of Gourgouthakas Cave
Introduction: Caves represent unique, nutrient-limited windows into the deep biosphere, yet the microbiology of the deep terrestrial subsurface remains remarkably under-explored. In this work, we took advantage of a rare […]

Microbes May Have Lived Underground For More Than 1 Billion Years
A study using the thermal history and biosignatures of the upper few kilometers of some of the oldest rocks on Earth place constraints on the evolutionary history of microbes in […]
