The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

Our understanding of Earth's rock-hosted subsurface biosphere has advanced over the past
two decades through the collection and analysis of fluids and rocks from aquifers within the …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

Microorganisms are employed to mine economically important elements from rocks,
including the rare earth elements (REEs), used in electronic industries and alloy production …

The two microaerophilic, Fe-oxidizing bacteria (FeOB) Sideroxydans ES-1 and Gallionella
ES-2 have single circular chromosomes of 3.00 and 3.16 Mb that encode 3049 and 3006 …

For decades the soil nematode Caenorhabditis elegans has been an important model
system for biology, but little is known about its natural ecology. Recently, C. elegans has …

This study deals with the effects of hydrodynamic functioning of hard-rock aquifers on
microbial communities. In hard-rock aquifers, the heterogeneous hydrologic circulation …

Here we review published studies on the abundance and diversity of terrestrial rock-hosted
life, the environments it inhabits, the evolution of its metabolisms, and its fossil biomarkers to …

Microbial life in the nutrient-limited and low-permeability continental crystalline crust is
abundant but remains relatively unexplored. Using high-throughput sequencing to assess …

Research on geologic carbon sequestration raises questions about potential impacts of
subsurface microbiota on carbon cycling and biogeochemistry. Subsurface, high‐CO2 …
