Summary: The study in Shihuadong, China, focused on a fossil perched Ca-deficiency spring system to understand the genesis and diagenesis of travertines. The travertines were mainly formed in high-temperature fluids with interaction with Gaoligong Group metamorphic rocks. The findings suggest the influence of water chemistry and local topography in travertine deposition.

Summary: A novel xylanase gene, xynDRTY1, was identified from Tengchong hot spring using a metagenomic approach. The gene was codon-optimized, synthesized, and overexpressed in Escherichia coli. The purified XynDRTY1 showed activity with various natural glycosides, exhibited optimal pH and temperature, and demonstrated stability, making it potentially useful for biotechnological applications.

Summary: This study analyzed the prokaryotic community structure and diversity in the water and sediment of different hot spring sites in Tengchong County, using geochemical characteristics and HTS of the V4 region of 16S rRNA. The results showed that temperature was the main factor influencing the microbial communities, and provided a basis for further research on hot spring microbial resources.

Summary: This study analyzed the microbial community and functional genes in six selected hot springs with different temperature and pH conditions using metagenomic sequencing. Crenarchaeota, Euryarchaeota, and Aquificae were found to be the dominant phyla. Bacteria were found to encode versatile carbohydrate active enzymes for polysaccharide degradation, while archaea tend to assimilate C1 compounds through carbon fixation. Nitrogen-deficient conditions led to fewer genes involved in nitrogen metabolism, while sulfur metabolism genes, particularly those associated with sulfide oxidation and thiosulfate disproportionation, were abundant and diverse.

Summary: This study discusses the hydrogeological characteristics of the Xiaguan Hot Spring and the Butterfly Spring near Dali in Yunnan of China, including hydrochemical type, rare earth element concentrations, and hydrogen and oxygen isotope values. The geothermal reservoir temperature and hydrological circulation types of the two springs differ from each other.

Summary: In this study, cultivation-dependent approaches were used to investigate virus diversity in hot springs in Tengchong, Yunnan, China. Eight different virus-like particles were detected, among which five new archaeal viruses were isolated and characterized. These viruses can infect acidophilic hyperthermophiles belonging to three different genera of the family Sulfolobaceae.

Summary: Active diazotrophic populations in hot springs of Tengchong, China were investigated through gene expression and diversity analysis. The results showed diverse active diazotrophs in the hot springs, with Aquificae dominating in high-temperature hot springs and Cyanobacteria and Nitrospirae dominant in low-temperature ones. The phylogenetic lineages of diazotrophs in Tengchong hot springs were found to differ significantly from other regions, indicating a geographical distribution pattern.

Summary: In this study, a functional Mcr-based methanogenesis pathway was discovered in a novel member of the family Archaeoglobaceae, Methanoglobus nevadensis. The production of methane in M. nevadensis was found to be highly sensitive to the Mcr inhibitor, stimulated by xyloglucan and xyloglucan-derived sugars, and accompanied by the consumption of molecular hydrogen and deuterium fractionation. The findings suggest that divergent Mcr-encoding archaea may be underestimated sources of biological methane in terrestrial and marine hydrothermal environments.

Summary: This study presents a paleomagnetic record of the geomagnetic field in Yunnan Province, China, over the past 90,000 years. The evolution of magnetic flux lobes and non-dipole field are found to be influenced by various factors and exhibit different trends during different periods, particularly related to the Siberian and North Atlantic flux lobes.

Summary: Knowledge about species' distributions is crucial in various fields, and the study on Thermophis hot-spring snakes reveals that their distribution is limited to geothermal sites in the Tibetan Plateau and Hengduan Mountains. Factors like hot-spring water parameters and landscape features play a significant role in influencing the presence or absence of these species.

Summary: This study investigates the spring-back behavior of advanced high strength steel using a thermal-mechanical simulator GleebleTM. Results show that increasing the cooling rate reduces spring-back and leads to spring-forward, due to the increased volume fraction of martensite.

Summary: Coordinated analysis of geochemistry and microbial community revealed regional variation in hydrothermal ecosystems. Low abundance microbial variants were cosmopolitan, while high abundance variants were region-specific. Results indicate that local tectonic and geologic characteristics shape the geochemistry and microbial assemblages of continental hydrothermal systems.

Summary: The terra rossa on the Cayman Islands is mainly sourced from wind-blown volcanic dust or Saharan dust, with a strong affinity to Saharan dust blown into the Caribbean region each year. The low SiO2/Al2O3 ratios of the Cayman terra rossa is attributed to the rarity of quartz. The formation of the terra rossa on the Cayman Islands has likely been an ongoing process for at least the last 5 million years.

Summary: Miocene carbonate successions on Shidao Island in the Xisha Islands, South China Sea, include formations formed of limestones and dolostones, with several intervals of unconformity-capped dolostones. The dolomitization process mainly occurred in strata with high porosities and permeabilities, suggesting that dolomitization was not limited to near-sea-level strata. The exact properties of the seawater that promoted dolomitization are still uncertain.
