This study uses lipid hydrogen stable isotope probing to estimate archaeal generation times in hot spring sediments, finding decadal-scale rates in Yellowstone and slower rates in El Tatio.

This paper identifies acetogenic methane-carbon monoxide comproportionation as an exergonic microbial metabolism that could support life in anoxic environments on Earth and other planetary bodies.

The paper quantifies iGDGT composition in thermal springs to investigate how pH and temperature influence crenarchaeol abundance and membrane lipid structure in archaea.

This study investigates the clumped isotope signatures of different methanogenic pathways and identifies factors influencing methane isotope compositions.

This study shows that lipid hydrogen isotope compositions in Sulfolobus acidocaldarius reflect growth water, offering a reliable hydrological proxy for extreme environments and planetary studies.

This study quantifies how temperature and methane monooxygenase enzymes affect clumped isotope signatures in aerobic methane oxidation by Methylococcus capsulatus (Bath).

This study investigates how metabolism and growth conditions affect hydrogen isotope signatures in archaeal lipids, supporting their use as paleohydrological proxies.

The paper compares hydrogen isotope composition in lipids of a wild-type and nfnAB mutant strain of Thermoanaerobacterium saccharolyticum to study hydrogen isotope fractionation mechanisms.
