Community Survey: Field-Based Studies And Sample Processing Facility
Scientists at Northern Arizona University are conducting a research study gathering views from members of the planetary science community on field-based studies and the interest in a potential centralized facility […]
Deep Microbial Colonization in 2-Billion-Year-Old Ultramafic Rock from the Bushveld Complex
Archean cratons may provide stable microbial habitats in the deep subsurface, as evidenced by the discovery of billion-year-old crustal fluids.
Phreatobacter aquiterrae sp. nov., Isolated From An Icelandic Subsurface Geothermal Aquifer
A novel bacterial strain, designated HK31-PT, was isolated from a deep subsurface geothermal aquifer in southwestern Iceland. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that the strain was […]
Extreme Arabian Environments And Their Microbiomes: New Frontiers For Astrobiology And Biosignature Discovery
Astrobiology assesses the habitability of planetary bodies and the potential for extraterrestrial life.
Microstructural And Biochemical Constraints On Cryptoendolithic Life In Atacama Halite: Implications For Extreme Habitability
Halite pinnacles from the Yungay area in the hyperarid core of the Atacama Desert harbor cryptoendolithic microbial colonies.
A Thousand Meters Deep: Vertical Profiling of the Subterranean Microbiome of Gourgouthakas Cave
Introduction: Caves represent unique, nutrient-limited windows into the deep biosphere, yet the microbiology of the deep terrestrial subsurface remains remarkably under-explored. In this work, we took advantage of a rare […]
Hawaiian Geothermal Fumaroles Contain Diverse and Novel Viruses
Microbial communities of geothermal habitats are central to understanding the evolution of life on Earth. Metagenomics has provided insight into the role of viruses in shaping microbial diversity of complex […]
Redox distribution Of Asgard Archaea And Co-occurring Taxa In Microbial Mats From An Early Proterozoic Ecosystem Analog
Eukaryotes originated from the symbiosis of an Asgard archaeon, the alphaproteobacterial ancestor of mitochondria, and possibly additional bacterial contributions.
Spectacular Fossil Treasure Trove Pushes Back Origins Of Complex Animals
A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before […]
