Biofilms are a form of collective life with emergent properties that confer many advantages
on their inhabitants, and they represent a much higher level of organization than single cells …

Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Microbial life in marine sediment contributes substantially to global biomass and is a crucial
component of the Earth system. Subseafloor sediment includes both aerobic and anaerobic …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

The Curiosity rover discovered fine-grained sedimentary rocks, which are inferred to
represent an ancient lake and preserve evidence of an environment that would have been …

Bathyarchaeota, formerly known as the Miscellaneous Crenarchaeotal Group, is a phylum of
global generalists that are widespread in anoxic sediments, which host relatively high …

Over the past century a number of models have been developed to explain the vast
stratigraphic distribution of authigenic dolomite. These models include hydrogeological …

The global geographic distribution of subseafloor sedimentary microbes and the cause (s) of
that distribution are largely unexplored. Here, we show that total microbial cell abundance in …

A great number of the bacteria and archaea on Earth are found in subsurface environments
in a physiological state that is poorly represented or explained by laboratory cultures …

The ability of microorganisms to withstand long periods with extremely low energy input has
gained increasing scientific attention in recent years. Starvation experiments in the …
