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.

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

The paper identifies a novel ancestral high redox potential quinone, methyl-plastoquinone, and shows its evolutionary origin predates the Great Oxygenation Event.

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