Significant progress is being made in the development of the next generation of low cost life
detection instrumentation with much smaller size, mass and energy requirements. Here, we …

Abstract Lost Hammer Spring, located in the High Arctic of Nunavut, Canada, is one of the
coldest and saltiest terrestrial springs discovered to date. It perennially discharges anoxic (< …

The permafrost soils of the high elevation McMurdo Dry Valleys are the most cold,
desiccating and oligotrophic on Earth. Rhodococcus sp. JG3 is one of very few bacterial …

Permafrost accounts for 27% of all soil ecosystems and harbors diverse microbial
communities. Our understanding of microorganisms in permafrost, their activities and …

Permafrost in the high elevation McMurdo Dry Valleys of Antarctica ranks among the driest
and coldest on Earth. Permafrost soils appear to be largely inhospitable to active microbial …

Permafrost is ground that remains at or below 0° C for two or more consecutive years. It is
overlain by an active layer which thaws and freezes annually. The difference between these …

Both culture-independent and culture-dependent analyses using Nanopore-based 16S
rRNA sequencing showed that short-term exposure of Antarctic soils to low temperature …

Perchlorate is a contaminant that can persist in groundwater and soil, and is frequently
detected in different ecosystems at concentrations relevant to human health. This study …

Permafrost harbours a diversity of cryophilic microorganisms that can be metabolically active
at sub-zero temperatures and likely play a role in global carbon cycling. This forum article …

The atmosphere may be Earth's largest microbial ecosystem. It is connected to all of Earth's
surface ecosystems and plays an important role in microbial dispersal on local to global …
