Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

The study of well-preserved organic matter (OM) within mineral concretions has provided
key insights into depositional and environmental conditions in deep time. Concretions of …

The study of hydrothermal travertines contributes to the understanding of the interaction
between physico‐chemical processes and microbial mats in carbonate precipitation. Three …

It is widely hypothesised that primeval life utilised small organic molecules as sources of
carbon and energy. However, the presence of such primordial ingredients in early Earth …

Ecologically friendly, vegetable-oil-based, self-generating, self-healing amorphous carbon
(aC) tribofilms were spontaneously formed on steel using no harmful additives. aC films are …

To comply with the high demand for efficient and sustainable lubrications, carbon-based
tribofilms and/or nanomaterials have emerged as a potential solution that can resolve the …

Deep‐sea hydrothermal systems provide ideal conditions for prebiotic reactions and ancient
metabolic pathways and, therefore, might have played a pivotal role in the emergence of life …

Soda lakes of the East African Rift Valley are hyperalkaline, hypersaline lakes extremely
enriched in Na+, K+, Cl−, CO 3 2−, HCO 3−, and SiO 2. In this paper, we investigate the …

Active hot springs are dynamic geobiologically active environments. Heat-and element-
enriched fluids form hot spring sinter deposits that are inhabited by microbial and …

Earth's crust contains a substantial proportion of global biomass, hosting microbial life up to
several kilometers depth. Yet, knowledge of the evolution and extent of life in this …
