Summary: Thermal ionization mass spectrometry (TIMS) is the standard method for obtaining precise Sr-87/Sr-86 isotopic ratios. However, our developed hydrofluoric acid coprecipitation method offers a low-cost, rapid, simple, and high-throughput alternative for analyzing red wine samples, effectively eliminating isobaric interference and matrix element inhibition.

Summary: This study examines prehistoric mobility and animal exploitation patterns at the Early to Mid-Holocene site of Huseby Klev in Sweden using isotope analysis of animal teeth. The results show that prehistoric communities undertook both short- and long-distance forays for hunting particular species. The study also suggests that glacial meltwater may have affected local oceanic Sr ratios.

Summary: The Fe isotopes of bulk Fe sulfides have become useful tools for understanding geochemical processes involving iron. However, these sulfides often occur as intergrowths, making it difficult to obtain accurate isotopic results. In this study, a natural pyrite sample (Tianyu-Py) from a magmatic Ni-Cu massive sulfide ore in China was evaluated as a reference material for Fe isotope analysis. The results showed that the Tianyu-Py pyrite is suitable for in situ microanalysis and could be used to track pyrite precipitation in biological and geological processes.

Summary: The study indicates that in late Neolithic to Copper Age central and southern Italy, human mobility was mainly influenced by local water sources and food resources primarily based on C-3 plants. There were significant variations in oxygen and carbon isotope values among different populations. Sedentary lifestyle seemed to characterize the investigated communities during this period.

Summary: The possibility of obtaining detailed individual mobility data from archaeological teeth was evaluated using laser ablation to analyse strontium isotope ratios. The results showed a high correlation and reasonable transition pattern between the laser ablation profiles and the traditional bulk data. This suggests that laser ablation technology can increase the amount of information obtained from a single tooth while causing minimal damage to the specimen.

Summary: The study of the origin and evolution of diagenetic fluids in Upper Jurassic carbonate rocks along the Zagros thrust-fold Belt revealed two major diagenetic stages involving a mix of seawater and freshwater in the initial stage, and a blend of meteoric water and hot fluids in the second stage. The high resolution analysis involved in-situ strontium isotope ratios, stable isotopes, petrography, and fieldwork to provide a comprehensive understanding of the diagenetic processes.

Summary: This study investigated the impact of HIV-1 virus production on cellular zinc homeostasis and isotopic fractionation. The researchers found that HIV-1 captures a significant amount of cellular zinc in newly produced particles, and cells accumulate lighter zinc isotopes from the growth medium. The viruses and producing cells exhibit similar isotopic fractionation. The study also demonstrated that enriched isotopes can be used to trace the fate of zinc in HIV-1 infected cells.

Summary: This study reports the uranium isotope ratios of twenty-nine geological reference materials, including various types of rocks and sediments. The measurements were done using a multi-collector inductively coupled plasma-mass spectrometer. The results show that most samples have U-234/238 values close to secular equilibrium, with minor fluctuations observed in Pleistocene speleothem samples. The U-238/235 values of igneous and metamorphic rocks are consistent with values found in the continental crust, while sedimentary rocks and sediments exhibit a wide range of values, indicating significant isotopic fractionation at low temperatures. The wider range of U-238/235 values reported in this study allows for inter-laboratory calibration of a broader range of geological and environmental samples.

Summary: The study revealed the movement patterns of an Arctic woolly mammoth that lived 17,100 years ago, showing variations in mobility across a geographically extensive range during its approximately 28-year lifespan. Maintaining such level of mobility for megafaunal species like mammoth would have become increasingly challenging as the ice age ended and the environment changed at high latitudes.

Summary: The potential of otolith microchemistry as a fishery management tool for different European freshwater fish species in an Alpine foreland was assessed in this study. Water samples from 26 habitat sites in a pre alpine catchment region were analyzed to determine the 87Sr/86Sr isotope ratios and Sr/Ca ratios, and 246 fish from 16 species were studied to determine the Sr/Ca ratios in otoliths. The study found that otolith microchemistry, when combining the 87Sr/86Sr and Sr/Ca ratios, has great potential to serve as a fishery management tool at smaller spatial scales.

Summary: Although there are already established bioindicator organisms and tissues, this pilot study aimed to find reliable and sensitive bioindicators in aquatic environments. The study found that calcified structures in fish, combined with commonly used fish soft tissues and intestinal parasites, were effective indicators of metal exposure in short- and long-term. Despite differences in metal contents, all applied bioindicators reflected similar environmental conditions, indicating higher levels of most elements in contaminated fish. The study confirmed the sensitivity of the intestinal parasites as bioindicators and highlighted the importance of continuous monitoring and protective actions in the polluted river.
