Whole-Genome Metagenomics Insights Revealed a Uranium Bio-remediating Cross-Domain Microbiome in the Dhala Impact Structure, India
[biorxiv.org] Meteorite impact structures on earth represent unique terrestrial analogues of extreme planetary environments where fractured lithologies, hydrothermal alteration, elevated concentrations of radionuclides, and prolonged water-rock interactions create ecological niches […]
![Effects of filtration method and sequencing platform on microbial abundance and community composition. Comparison of microbial abundance, sequencing performance, and taxonomic composition among Yellowstone hot spring samples processed using Sterivex, Supor, and polycarbonate (PC) filtration devices and analyzed by Illumina and Oxford Nanopore sequencing. Upper panels show absolute microbial abundance estimates (black bars) and sequence read lengths (red symbols). Lower panels depict species-level relative abundances of dominant bacterial and archaeal (red asterisk) taxa recovered from each sample. -- [biorxiv.org]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Differential-efficiency.png?resize=1200%2C708&ssl=1)

Differential Efficiency Of Sampling Devices In The Measurement Of Microbial Diversity Of Yellowstone National Park Hot Springs
[biorxiv.org] Metagenomic characterization of low-biomass Yellowstone National Park (YNP) hot spring waters remains challenging because microbial recovery is influenced by filtration methodology, sample preservation, DNA extraction, and sequencing strategy.

Genomic Adaptations Of Novel Halotolerant Bacteria From Extreme North Greenland
Peary Land, northern-most Greenland, is a cold desert region whose soil microbiome remains underexplored. This is the first study to explore the halotolerant soil microbiome of this region with culture-dependent […]
![Contribution of springs to the lake. (A) Venn diagram of genera found in the Corral Springs biofilm, salt crust, Springs 1 and 2 (S1, S2 combined), Roberts Ranch/Wyman Creek (RS), and the lake water. (B) Mixing proportions calculated using SourceTracker using the lake water samples (LW1, LW2, and overnight incubated [ON]) and the salt crust as sinks, and the biofilm, RS, S1 and S2 as sources. “Unk” indicates “unknown source.” The Gibbs sampler was run for 10,000 iterations. -- Frontiers](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Microbial-communities-of-selected.png?resize=1200%2C720&ssl=1)
