Commun Earth Environ
. 2025 Jan;
5(1):795.
PMID: 39742000
Characterizing deep subsurface microbial communities informs our understanding of Earth's biogeochemistry as well as the search for life beyond the Earth. Here we characterized microbial communities within the Kidd Creek...

Nat Commun
. 2024 Oct;
15(1):9130.
PMID: 39443486
The deep continental crust represents a vast potential habitat for microbial life where its activity remains poorly constrained. Organic acids like acetate are common in these ecosystems, but their role...

. 2024 Aug;
263:122149.
PMID: 39098153
Sulfidated nanoscale zerovalent iron (S-nZVI) has demonstrated promising reactivity and longevity for remediating chlorinated volatile compounds (cVOC) contaminants in laboratory tests. However, its effectiveness in field applications remains inadequately evaluated....

Hydrogeological controls on microbial activity and habitability in the Precambrian continental crust
Song M, Warr O, Telling J, Lollar B
Geobiology
. 2024 Mar;
22(2):e12592.
PMID: 38445449
Earth's deep continental subsurface is a prime setting to study the limits of life's relationship with environmental conditions and habitability. In Precambrian crystalline rocks worldwide, deep ancient groundwaters in fracture...

Nisson D, Walters C, Chacon-Patino M, Weisbrod C, Kieft T, Lollar B, et al.
Nat Commun
. 2023 Oct;
14(1):6163.
PMID: 37789019
Investigations of abiotic and biotic contributions to dissolved organic carbon (DOC) are required to constrain microbial habitability in continental subsurface fluids. Here we investigate a large (101-283 mg C/L) DOC...

Nature
. 2023 Mar;
615(7950):94-99.
PMID: 36859584
Helium, nitrogen and hydrogen are continually generated within the deep continental crust. Conceptual degassing models for quiescent continental crust are dominated by an assumption that these gases are dissolved in...

Nat Commun
. 2022 Oct;
13(1):5790.
PMID: 36184637
Distinguishing biotic compounds from abiotic ones is important in resource geology, biogeochemistry, and the search for life in the universe. Stable isotopes have traditionally been used to discriminate the origins...

. 2022 Jun;
98(8).
PMID: 35700008
Reductive dehalogenases (RDases) are corrinoid-dependent enzymes that reductively dehalogenate organohalides in respiratory processes. By comparing isotope effects in biotically catalyzed reactions to reference experiments with abiotic corrinoid catalysts, compound-specific isotope...
