Abstract Elysium Planitia is the youngest volcanic terrain on Mars, and only region that exhibits evidence of ongoing magmatic activity today. This makes crucial for understanding tectonic, magmatic, volcanic, thermal state planet. The 2014–2015 Holuhraun eruption in Icelandic Highland provides a unique opportunity to study large-volume, fissure-fed eruption—with associated lava–water interactions—that serves as terrestrial analog terrains Planitia. Here, we detail key similarities between sites, including their geological settings, prominent lava morphologies, implications inferring dynamics. Even absence global plate tectonics both locations exhibit young fissure systems, indicating an extensional tectonic setting. Detailed investigations morphologies offer valuable insights into dynamics evolution eruptions. Of particular importance are “transitional” lavas, which, at site, with different effusion rates stages. presence inflation features disrupted surfaces supports interpretation these rubbly flows formed association high local strain rates, implying initial rate. However, polygonal terrain, which indicative low rate conditions, change cooling under broadly stagnant conditions. Due its variety recent geologic processes, potentially aqueous flows, pristine surfaces, well activity, compelling target future exploration.

Geothermal ecosystems are defined by extreme environmental conditions, such as elevated temperatures, high concentrations of toxic chemicals, and fluctuations in abiotic stressors, which shape plant survival adaptation. These unique ecosystems, found across various geothermal regions globally, support specialized communities that have developed distinctive morphological, physiological, ecological adaptations. Indonesia, located on the Pacific Ring Fire, is one world’s richest nations, offering an important yet underexplored context for studying vegetation zones. This review examines conditions adaptive strategies vegetation, patterns diversity within Indonesian fields. It also explores succession, community dynamics, potential use indicators biomonitoring. Despite growing interest, significant research gaps remain, particularly long-term monitoring integration molecular-level studies. Addressing these essential enhancing scientific understanding informing conservation sustainable energy development tropical regions. highlights significance underscores need interdisciplinary to both biodiversity preservation responsible exploitation.

Abstract Planetary analog mission simulations are essential for testing science operations strategies and technologies. They also teach us how to use terrestrial analogs inform studies of extraterrestrial environments. Unoccupied aircraft systems (UASs) have great potential planetary surface exploration as demonstrated by the Mars 2020 Ingenuity helicopter in-development Dragonfly Saturn’s moon Titan.

In this study, we designed and validated in silico experimentally a rapid, sensitive, specific multiplex RT qPCR for the detection quantification of faecal indicator bacteria (FIB) used as microbiological references marine bathing water regulations (Escherichia coli intestinal enterococci). The 16S rRNA gene was to quantify group-specific enterococci Escherichia/Shigella species-specific such Enterococcus faecalis E. faecium. Additionally, ybbW encoding allantoin transporter protein detect coli. An assessment coastal systems (i.e., sediment) revealed that were predominant group compared Escherichia/Shigella. low contribution reported. As faecium reported at concentrations, it is assumed other origin are contributing high copy number enterococci. Moreover, numbers with respect seawater sediment. We conclude sediments can affect FIBs included regulations. Valuing quality system through sediment monitoring recommended.
