DOI: 10.1038/s41467-020-17330-1
Abstract: Sparse microbial populations persist from seafloor to basement in the slowly accumulating oxic sediment of the oligotrophic South Pacific Gyre (SPG). The physiological status of these communities, including their substrate metabolism, is previously unconstrained. Here… read more here.

DOI: 10.1038/s41561-018-0190-9
Abstract: The colonization of emergent continental landmass by microbial life was an evolutionary step of paramount importance in Earth history. Here we report direct fossil evidence for life on land 3,220 million years ago (Ma) in the… read more here.

DOI: 10.1038/s41598-019-47394-z
Abstract: Here we inspect whether microbial life may disperse using dust transported by wind in the Atacama Desert in northern Chile, a well-known Mars analog model. By setting a simple experiment across the hyperarid core of… read more here.

DOI: 10.1038/s41598-020-73938-9
Abstract: Loess-paleosol sequences are terrestrial archives of past climate change. They may host traces of ancient microbial life, but little information is available on the recovery of microbial biomarkers from such deposits. We hypothesized that microbial… read more here.

DOI: 10.20870/oeno-one.2018.52.3.2120
Abstract: Aim: Recent studies have shown that plants harbor complex bacterial communities, the so-called “microbiome”. We are only beginning to unravel the origin of these bacterial plant inhabitants, their community structure and their roles, which, in… read more here.
