Summary: This study aims to compare the application of general-purpose and special-purpose methods in evaluating geosites with geomorphological and other geological interest. The results show differences in assessment scores between the two approaches, but overall, both types of methods can be applied without strongly affecting the final results for geosites.

Summary: Considerable landscape changes due to a planned salt-harvest disposal project in the unique Dead Sea environment can be mitigated using the geochemical and engineering solution presented in this study. The study examines the feasibility of dissolving and disposing of the dredged halite in a dissolved state in the Dead Sea using seawater or desalination reject brine. The results show that the high solubility and fast dissolution kinetics of halite in seawater/brine are sufficient for disposal.

Summary: This paper discusses the potential geotourism resources related to petroleum geology in the Middle Magdalena Valley Basin of Colombia, and proposes geotourism as a strategic choice for promoting sustainable tourism. The region is rich in geological and anthropic features, making it suitable for geoeducation and geotourism activities.

Summary: Understanding the long-term radiation environment at the surface of Mars is important for future missions. Previous studies used in-situ measurements or models to determine the radiation characteristics. To address a gap in knowledge, researchers developed an approach to derive the surface neutron spectrum using data from the RAD instrument and the HEND detector onboard Mars Odyssey.

Summary: A novel fluorescence assay based on hyperbranched rolling circle amplification (HRCA) and DNA walkers was proposed to detect ultrasensitive CpG methyltransferase (M.SssI) and DNA adenine methyltransferase (Dam) activity. The biosensor showed high sensitivity due to the dual-amplification strategy of HRCA and DNA walkers. M.SssI and Dam methyltransferase could be detected with limits of detection (LOD) of 0.0004 U/mL and 0.001 U/mL, respectively. The sensing system was also applied to analyze endogenic Dam methyltransferase in real samples such as E. coli cell lysate.

Summary: The study found that fishing industry perspectives on sea-level rise risk and adaptation in three Florida coastal communities vary across sectors and communities, influenced strongly by experience, community dynamics, and age. Older fishers are less willing to relocate due to social factors like place attachment, while younger fishers are more likely to retreat or work from a less vulnerable location. These findings suggest that adaptation responses are mediated by age, attachment to place, and worldviews, and need to be considered when crafting adaptation strategies across coastal communities.

Summary: The Seroglazovka locality in the Lower Volga region is a key site known for its genetically variable Middle and Upper Pleistocene deposits containing diverse flora and fauna. Through an integrated study, regional horizons and subhorizons within the Quaternary interval at this locality were confidently stratified, shedding light on the main Pleistocene paleoenvironments and their evolution in the area.

Summary: This review examines data on the Base Miocene Unconformity and the tectono-stratigraphic development of the Sabah to Palawan region. It challenges previous plate tectonic models and proposes that the plate drift in the South China Sea was not linked to subduction processes in western Sabah. The absence of plate docking and compression further supports this proposal.

Summary: This study investigates the effects of heliospheric factors on galactic cosmic rays during the minimum phases of sunspot cycles. It focuses on determining the maximum intensity of GCRs during sunspot minima and the relationship with the solar magnetic field. Special attention is given to the energy at which spectral cross-overs occur and their relation to the changing polarity of the heliospheric magnetic field.

Summary: This article demonstrates the dynamics of the gravitational lifting system in the deep sea mining industry. Through quantitative analysis, it is found that bucket size is the most influential factor, positively correlated with lifting speed and production rate. The feasible design of the lifting system should take into consideration the breaking strength of the cable wire rope and optimize the combination of bucket size and distribution distance based on specific working conditions.

Summary: In this paper, a combined method of GCR Block Ack and Unsolicited Retry is proposed for lossless binary data groupcast over wireless LANs. The proposed method utilizes IEEE 802.11aa GCR mechanisms for audiovisual transmission. By transmitting each frame twice without acknowledgment and entering the Block Ack sequence, the proposed method improves the performance under lossy wireless link conditions. The integration of TXOP-Bursting further enhances the efficiency by allowing high priority sequential frame transmission within the specified time limit.

Summary: Radiation is a vital concern for astronauts, especially the radiation from Solar Energetic Particles (SEPs) and Galactic Cosmic Rays (GCRs), which can have adverse effects on the Central Nervous System (CNS). Through calculations and evaluations of radiation dose, this study finds that the CNS of astronauts on the Martian surface is generally safe, but those on the lunar surface or in deep space may face radiation risks if not well shielded.

Summary: The aim of this study is to construct acute aquatic species sensitivity distributions (SSD) and proposed HC5 values for two aquaculture anti-sea lice bath pesticides, azamethiphos and hydrogen peroxide, which can be used to establish environmental quality standards (EQS). Through the examination of literature data and using limited exposure times, SSDs and HC5 values for mortality and sublethal endpoints have been generated for each pesticide. The resulting threshold concentrations in environmental seawater are 0.10 μg/L for azamethiphos and 0.15 mg/L for hydrogen peroxide. Further considerations and study are needed to better understand the environmental risks of using these bath pesticides.

Summary: The study highlights the significant leakage issues in the coastal aquifer near the Dead Sea, which were addressed by constructing a vertical deep sealing wall. Based on the model predictions, it is projected that the leakage volume is likely to increase in the coming decades.

Summary: Ailsa Craig in the Firth of Clyde is the southern-most intrusion of the British Palaeogene Volcanic Province in Scotland, known for its granitic rocks used in making curling stones. These rocks are believed to have formed from fractionation of a mantle-derived basic magma without crustal contamination. The presence of rare alkaline ferromagnesian minerals makes the Ailsa Craig intrusion unique in the BPVP.
