Summary: This study used radiocarbon dating and luminescence dating to analyze samples from the Ban Bo Suak archaeological site in northern Thailand, revealing the temporal origin of Lanna ceramics and their connection to floods. The results indicate that the production of Lanna-style ceramics continued despite the destructive floods.

Summary: The IntCal family of radiocarbon calibration curves, based on over three decades of research, has collated C-14 and calendar age data and made them available through an open-access database since 2010. The aim is to provide transparency in terms of the data used in constructing the calibration curves.

Summary: This study revises the chronological framework of the Telarmachay rockshelter, a key site in the Andean highlands, by conducting a new AMS dating program. The results provide a greater than 5000 year sequence of occupation and highlight the importance of the Junin area in the Andean highland occupation sequence. It emphasizes the need for new radiocarbon dates to reassess previous data and directly date artifacts.

Summary: A new biennial record of radiocarbon measured in Danish oak covering the years 1251-1378 CE shows changes in the Hale and Schwabe solar cycles during the Wolf Minimum. The record's spectral analysis revealed peaks at 27 and 9.1 years, suggesting alterations in these cycles, but further research is needed to confirm these findings. The study also reconstructed the solar modulation function indicating a periodicity of approximately 9 years preceding the Wolf Minimum.

Summary: Glacier-based reconstructions of Equilibrium Line Altitudes (ELAs) are crucial for understanding long-term changes in temperature and precipitation. Our study focuses on the south-eastern part of the European Alps during the Last Glacial Maximum (LGM), providing new insights into the ELA based on geomorphological evidence.

Summary: This study reconstructs the glacier fluctuations in the northwestern Himalaya using a relict proglacial lake succession, finding that valley glaciers expanded during MIS-2 and persisted until the Last Glacial Maximum. The early part of MIS-2 was driven by temperature decrease, while extensive glacier growth in mid MIS-2 was mainly contributed by enhanced moisture.

Summary: This study compared two methods for extracting a-cellulose from wood and found the most optimal method for high-precision radiocarbon analysis. The use of HCl acid for delignification was determined to be the most effective for pretreatment of tree rings at AARAMS.

Summary: Atmospheric CO2 samples collected since the 1960s have been stored as CaCO3 in glass containers. The study investigated whether the stored samples can still be used for new measurements of atmospheric radiocarbon content and whether they have been contaminated. Various methods were attempted to clean the carbonate and release CO2 for remeasurements. The results showed significant changes in C-14 content for samples before 1970, indicating contamination during storage, and later samples from the 1970s showed lower contamination but still had added uncertainty, making them unreliable.

Summary: Zircon is a widely studied mineral for geochronology, and its Th/U ratios play a critical role in isochron dating and radiometric age correction. However, the processes causing Th/U variations in zircon crystals are not fully understood. This study presents new data on the Th/U ratios and ages of zircon from a volcanic eruption in central Chile, providing important insights into the factors influencing Th/U ratios in zircon.

Summary: The study aims to constrain the sedimentary evolution of the back-barrier mangrove in Can Gio based on stratigraphic, palynological and geochronological analyses of sediment cores. Major episodes of subtidal mud aggradation from 6 to 3.5 ka formed the topography for mangrove development.

Summary: In the Arctic regions, the groundwater in a sandy aquifer studied has primarily atmospheric recharge far from the river and significant contribution of river water in the coastal zone. The groundwater age ranges from 20-25 years in onshore wells, but also contains bomb water and old water before 1952. The distribution of tritium isotopes clarified the conditions of groundwater recharge and the ratios of young water, bomb water, and old water in different parts of the aquifer.

Summary: This article describes the process of the National 1MV Accelerator Mass Spectrometry (AMS) Laboratory in Turkey offering radiocarbon (C-14) analysis service internationally. The laboratory provides services including sample evaluation, preparation, measurement, and consultancy. The laboratory also has systems for CO2 conversion and a 1MV UAMS NEC Pelletron system for natural level C-14 samples. In addition to commercial activities, the laboratory can contribute to research projects.

Summary: In late Quaternary Chinese loess-palaeosolar deposits, the reliability of radiocarbon dating different small snail shells remains uncertain. This study collected snail shells of various sizes from a loess-palaeosol sequence in central China and used AMS measurements to evaluate their radiocarbon ages. The results showed that small-snail-shell 14C dating is generally reliable in Chinese loess deposits, with consistent ages between graphitized samples and corresponding OSL ages. The study also highlighted the varying reliability of different snail species, emphasizing the need for careful selection of shells for larger taxa.

Summary: The application of Zooarchaeology by Mass Spectrometry (ZooMS) has been successfully used in Europe and northern Asia to discover new hominin fossils and expand the range of identified fauna. However, its application in Palaeolithic sites in East Asia has not been systematically attempted. This study analyzed 866 morphologically non-diagnostic bones from Jinsitai Cave in northeast China and Yumidong Cave in South China, and found a high degree of collagen preservation and potential time-related deamidation patterns. The study also identified camel bones in Jinsitai, providing evidence of megafauna taxon targeted by early modern humans during their expansion in northeast Asia. This large-scale application of ZooMS in China highlights its potential in advancing our knowledge of the palaeoanthropological and zooarchaeological records of East Asia.

Summary: Stable isotope analysis sheds light on the dietary structure and living environment of early state-level societies on the north coast of Peru. The study found that the stable isotope signature of one individual differed from previous research, suggesting possible highland residence during childhood.

Summary: The dataset compiles oxygen and hydrogen isotope data of meteoric water samples from multiple States across Mexico, enabling the creation of isoscapes to determine the spatial distribution of water stable isotopes. This dataset is valuable for geographic mobility studies and can be utilized in various research fields such as archaeology, bioarchaeology, forensics, hydrogeology, and ecology.

Summary: The study found that the sacrifices at Tlatelolco were mostly locals or long-term residents, while the sacrifices at Templo Mayor were mostly non-locals and long-term residents for subadults, and long-term residents or non-locals for adults. This suggests that the Templo Mayor priests had access to a diverse range of individuals for sacrifice with different origins.

Summary: The Vira population is believed to have formed a centralized polity in the Vira Valley, with occasional settlements in neighboring regions. Their presence is identified by negative ceramic cultural markers. By using technological methods to reconstruct Vira ceramic production, it is possible to verify the hypothesis of Vira communities moving into adjacent valleys.
