Summary: The study found that cadmium in continental margin sediments exists mainly in organically bound and sulfide forms, with isotopic compositions lighter compared to seawater. These observations indicate a downward diffusive flux of seawater cadmium and redox-driven removal of cadmium during sulfide precipitation.

Summary: This review examines the marine distributions of the micronutrient cadmium (Cd) and its stable isotope composition, challenging the previous belief that Cd loss mainly occurs in the oxygen minimum zones. The study shows that the extreme plasticity in the cadmium:phosphorus (Cd:P) stoichiometry of biological uptake is the most important control on marine Cd distribution. The authors also suggest that the Cd loss observed in the tropical regions may be related to biological activity rather than CdS formation. The findings highlight the need to reevaluate the role of particle-hosted CdS formation in the marine mass balance of Cd.

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: The study analyzed sedimentary sequences from the Early Cambrian Niutitang Formation in the Nanhua Basin, South China, revealing strongly oxidized and highly productive surface water layers during this period. The combination of cadmium and chromium isotopes indicated a sulfide-controlled Cd enrichment under restricted euxinic conditions, with less effective precipitation of Cd likely under more suboxic conditions in an open shallow shelf environment.

Summary: This study identifies the sources of cadmium in the Xijiang riverine system in China as natural weathering and acid mine drainage using chemical and isotope analysis. The isotopic fractionation of cadmium is mainly controlled by the composition of acid mine drainage. The study highlights the use of cadmium isotopic fractionation as a tool to distinguish the effects of anthropogenic activities from natural weathering processes in river systems at risk of cadmium pollution.

Summary: The distribution of cadmium in oceans suggests its use as a nutrient by marine phytoplankton. This study focuses on tying the Cd isotopic record in modern carbonate to conditions in upper water column and suggests that δCd-114 values in carbonates are a reliable tool for reconstructing past bioproductivity levels. The burial and diagenetic processes of carbonate are postulated not to modify the Cd isotope signals, indicating the potential use of δCd-114 values in carbonates for reconstructing past ocean redox conditions.

Summary: Cadmium isotopes show preferential enrichment of light isotopes bound to humic acid, leaving heavier isotopes in solution. Fractionation of Cd isotopes at high ionic strengths depends on complexation with carboxylic sites, while at low ionic strengths, nonspecific Cd binding due to electrostatic attractions plays a dominant role in isotope fractionation.

Summary: This study found that alfalfa seedlings soaked in saturated argon-rich water (ARW) showed improved growth under cadmium stress. The addition of ARW reduced cadmium uptake and accumulation in both root and shoot parts of the plant, and restored glutathione and redox balance, enhancing tolerance against cadmium toxicity.

Summary: The study found that soil flooding promotes the binding of Cd to S and results in the enrichment of heavy Cd isotopes in plants in soil-rice systems rich in Cd and S. Excluder rice roots strongly retain light Cd isotopes, while the difference in isotope composition between roots and shoots is smaller in non-excluder rice plants.

Summary: The application of zinc and cadmium isotopes in carbonate sediment as palaeo-proxies is expanding rapidly. However, there are limited investigations into the chemical cleaning methods required for accurate data. This study assessed the performance of two standard chemical cleaning protocols and recommended the use of a specific method for consistent and accurate data.

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: 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.
