Summary: The most neutron-rich sodium nucleus observed so far, 39Na, was discovered at the RIKEN Nishina Center Radioactive Isotope Beam Factory. The study confirms the particle stability of 39Na and provides new key information for understanding nuclear binding and structure under extremely neutron-rich conditions. This discovery has significant implications for nuclear models and theories predicting the neutron dripline and sheds light on the nuclear shell property of 39Na at the neutron number N = 28.

Summary: Elevated concentrations of arsenic were found in boreal freshwater fish, particularly in riverine fish compared to lacustrine fish. Arsenobetaine and dimethylarsinic acid were the only detected arsenic species. The percentage of arsenobetaine was higher in riverine fish, while the percentage of unmeasured arsenic was lower.

Summary: Arsenic is a toxic substance widely distributed in the environment, and understanding the genetic determinants of arsenic resistance and metabolism is important for remediation efforts. Bacteria, including strains isolated from a gold and copper mine, have developed mechanisms to tolerate and detoxify arsenic. The presence of arsenic in gold-bearing minerals poses a hazard during mining activities. The identification of specific genes and operons involved in arsenic resistance can inform strategies for remediation.

Summary: The origin and co-cycling of nitrogen species in arsenic-prone groundwater remain poorly understood, which could affect arsenic behavior. This study investigated the geochemical and multi-isotopic characteristics of groundwater in different redox environments to reveal the effects of nitrogen cycling on arsenic mobility.

Summary: Bioaccumulation through diet is the main source of metal(loid)s in fishes. This study investigated the diet compositions of aquatic organisms and their potential food sources using stomach content analysis, stable isotope analysis, and a Bayesian mixing model. The results showed that aquatic organisms mainly obtained their nutrients from fine particulate organic matter and epilithon, with smaller contributions from leaf litter, coarse particulate organic matter, and fish.

Summary: This study investigates the arsenic contamination in groundwater in the central Yinchuan basin. The results show that high levels of arsenic were found mainly in the northern and eastern areas along the Yellow river. The main sources of arsenic were the dissolution of arsenic-bearing minerals in sediment, irrigation water infiltration, and aquifer recharge from the Yellow river. The study also highlights the high health risk, especially the carcinogenic risk, associated with arsenic pollution in groundwater.

Summary: The use of scrap steel is expected to increase in order to reduce carbon emissions. However, the enrichment of residual elements in steel production during recycling has become a problem. This study investigates the formation of arsenic compounds in La-added molten steel, identifying two compounds - La-S-As and La-As - for the first time. These compounds mainly consist of La-S-As, La-As, and LaAsO4, with La4S3As identified as a solid solution resulting from the replacement of S atoms with As in LaS. La4S3As started to form in molten steel and aggregated to generate large clusters that floated up mostly, providing a new strategy for reducing residual elements in molten steel represented by arsenic.

Summary: This article investigates the evolution of groundwater chemistry in the mid Gangetic floodplain, revealing that irrigation return flow is partly responsible for arsenic enrichment. The study also shows that geomorphological features and isotopic tracers point to meandering and oxbow formations as leading to arsenic contamination.

Summary: This study systematically reports the large-scale helium enrichment along the continental convergent margin for the first time. It identifies a 1200-km-long helium enrichment zone and demonstrates the complex crustal-scale structures significantly controlling gas geochemistry in the convergent margin. These findings have profound implications for potential helium resource exploration and He-CO2-N-2 recycling in continental subduction zones.

Summary: This article challenges Gareth Eaton's claim that Theodore Richards should be considered one of the discoverers of isotopes. Drawing on two influential theories of scientific discovery developed by Thomas Kuhn and Augustine Brannigan, the author argues that although Richards' experimental work contributed to the discovery, it does not warrant attributing the discovery to him.

Summary: The study reveals that the Ali-Sabieh aquifers in the East African Rift System are overexploited and contaminated with high concentrations of nitrate and sulfate, originating from anthropogenic activities and geological processes. The groundwater samples show a chemical evolution from fresh to brackish water mainly due to water-rock interaction.

Summary: Subjecting a physical system to extreme conditions is a common method to gain a better understanding of its organization and structure. The investigation of isotopes with different neutron-to-proton ratios than stable nuclei is an important test for nuclear-structure theories. This study reports the first observation of the decay of O-28 and 27O isotopes and compares their decay energies with theoretical models. The results have implications for the understanding of nuclear structure.

Summary: This study investigates nucleon removal reactions and validates the models used to calculate the removal reaction cross sections. Three different nucleon removal reactions were performed and the partial cross sections to individual final states were determined by detecting the residual nuclei in coincidence with gamma rays. Comparison between measured and calculated cross sections reveals that the theoretical description of the removal process is in better agreement with the data when removing weakly bound nucleons.
