OBJECTIVE: Intersectionality posits that multiple levels of marginalization interact to produce patterns of frailty and mortality, both today and in the past. To investigate how mortality during industrialization was selective with respect to sex and socioeconomic status (SES), this study analyzes data from four burial grounds dated to the 18th-19th centuries in England: St. Bride\'s Fleet Street, Coach Lane, St. Peter\'s Collegiate Church, and New Bunhill Fields.
METHODS: St. Bride\'s was considered the high SES group, and Coach Lane, St. Peter\'s, and New Bunhill Fields were separately and collectively analyzed as the low SES groups. Sex (in individuals aged 18+ years) was modeled as a covariate affecting the Gompertz model of mortality, and SES (in individuals for whom age could be estimated) was modeled as a covariate affecting the Siler and Gompertz models of mortality.
RESULTS: The results indicate that sex influenced risk of mortality among adults in the high SES group. High SES males faced lower risks of death compared to high SES females. The results also suggest that SES influenced risk of mortality across all ages. High SES individuals were at reduced risks of death compared to low SES individuals.
CONCLUSIONS: Increased mortality risks among individuals of low SES was likely due to the low standards of living common in the impoverished areas of cities in industrializing England. However, in accordance with intersectionality, the benefits of high status were unequally distributed among adults in the high SES group, suggesting that men were the primary beneficiaries of the protective aspects of high SES.

An ethical paradigm shift currently taking place within biological anthropology is pushing scholars to envisage and develop paths toward more ethical futures. Drawing from case studies in our own teaching, research, and fieldwork experience, we reflect on the complex, diverse, and dynamic nature of ethical considerations in our field. We discuss the acquisition and institutional narrative of a human osteological teaching collection at the University of Louisville as an embodiment of structural apathy turned structural violence, and the need for professional guidance in the potential retirement of deceased individuals from our classrooms. In documented collections (i.e., the Robert J. Terry Collection), we share our process and scholarly reemphasis of the humanity of a deceased individual through contextualized analysis (i.e., osteobiography and archival history) and postmortem agentive acts. Lastly, we present an archeological site in the U.S. Virgin Islands, which poses ethical concerns as biocultural bioarcheologists and archeologists attempt to negotiate the possible wishes of the deceased with the cultural value of reconstructing the community\'s otherwise undocumented past, all amidst the immediate threat of anthropogenic climate change. We offer these exercises and discussion in ethically engaged projects transparently and with an overarching admission that none are models for replication. Rather, at various stages in our careers and engagement with ethics, we acknowledge that progress is worthwhile, albeit challenging, and that proceeding forward collectively as biological anthropologists should be deliberate, reflexive, and compassionate for deceased individuals and their descendant communities, as well as among and between colleagues.

BACKGROUND: Although the macroscopic assessment of dental caries and the assessment of bone elemental composition are quite different, efforts can be made to identify commonalities in the assessment of health and nutritional quality. Both indicators are correlated with dietary habits and are dependent on taphonomic processes occurring in the postmortem substrate. However, teeth exhibit structural resilience of their hard tissues to adverse environmental factors.
OBJECTIVE: The aim of the study was to establish a correlation between the elemental composition of bones and the presence of carious lesions.
METHODS: The study material consisted of the following skeletal parts: 161 permanent teeth from 36 individuals and bridge fragments of 36 ribs. The presence of caries was assessed visually using a modified International Caries Detection & Assessment System (ICDAS II) scale. The rib samples were subjected to elemental analysis (zinc (Zn), iron (Fe), magnesium (Mg), calcium (Ca), phosphorus (P), strontium (Sr), barium (Ba)) using spectroscopic methods.
RESULTS: The odontological and chemical analyses did not reveal any statistically significant relationships between the Ca/P diagenesis index and dental features. Postmortem tooth loss showed a weak correlation with the diagenesis index.
CONCLUSIONS: Discoloration, cracks and flaking of the dental crown surfaces may be associated with the intensity of Ca/P diagenesis. However, no significant correlation was found between these phenomena. Among other elements, only Zn levels exhibited a correlation with the caries index.

Sedimentary ancient DNA (sedaDNA) has become one of the standard applications in the field of paleogenomics in recent years. It has been used for paleoenvironmental reconstructions, detecting the presence of prehistoric species in the absence of macro remains and even investigating the evolutionary history of a few species. However, its application in archaeology has been limited and primarily focused on humans. This article argues that sedaDNA holds significant potential in addressing key archaeological questions concerning the origins, lifestyles, and environments of past human populations. Our aim is to facilitate the integration of sedaDNA into the standard workflows in archaeology as a transformative tool, thereby unleashing its full potential for studying the human past. Ultimately, we not only underscore the challenges inherent in the sedaDNA field but also provide a research agenda for essential enhancements needed for implementing sedaDNA into the archaeological workflow.

OBJECTIVE: This study seeks to identify signals of the male-female health-survival paradox in medieval London.
METHODS: This study uses skeletal data on age, sex, dental caries (n = 592) and antemortem tooth loss (n = 819) from adult individuals from medieval London cemeteries (c. 1200-1540 CE). The association between age and dental caries was assessed using binary logistic regression. The associations among age, time period (pre- vs. post-Black Death), oral biomarker (dental caries or antemortem tooth loss), and sex were tested using hierarchical log-linear analysis.
RESULTS: The analyses reveal significantly higher odds of dental caries with increasing adult ages, more older adults after the Black Death, different age distributions of dental caries between the sexes, and a greater decrease in the prevalence of dental caries for females after the Black Death. These results appear not to be an artifact of trends in AMTL. However, this study does not yield evidence suggesting that females experienced both a survival advantage and a decline in oral health at late adult ages after the Black Death relative to males.
CONCLUSIONS: These results do not provide evidence of the existence of a male-female health-survival paradox, but they do corroborate existing evidence of improvements in health in general in the aftermath of the Black Death. The decreased prevalence of dental caries after the Black Death may reflect dietary improvements or the effects of selective mortality during the epidemic.

OBJECTIVE: The skeleton embodies an individual\'s environment and lived experiences. Studying childhood growth disruption can, therefore, aid in understanding the experiences of children in the past. This study evaluates growth disruption in a medieval Toulousian subadult sample to explore factors that may have influenced childhood growth and mortality at this site and to assess the utility of Harris line (HL) interpretations in bioarchaeology.
METHODS: Femoral growth disruption was assessed in n = 71 subadults (0.125-12.42 years) from the 10th-13th century St. Étienne cemetery of Toulouse, France, using femoral length, total area, cortical area, and relative cortical area. Femoral radiographs were assessed for HLs. To determine the prevalence of growth disruption, z-scores were calculated using data from the Denver growth study.
RESULTS: The majority of subadults in this sample suffered from femoral growth disruption. Young children (1.0-3.99 years) were the most affected, with >65% experiencing reduced appositional growth and linear growth stunting at time-of-death. Additionally, while many individuals presented with observable HLs, linear and appositional growth did not significantly differ between individuals with and without HLs.
CONCLUSIONS: Maternal malnutrition and inadequate complementary feeding practices likely contributed to the high prevalence of growth disruption among the youngest individuals in the study. The older children and adolescents buried at St. Étienne experienced an amelioration in growth deficits, indicating an improvement in nutrition and/or disease load. The results of this study suggest that more consideration is required when interpreting the presence/absence of HLs, and that studies assessing HLs may benefit from using a more individualistic approach.

This article presents a multidisciplinary approach adopted in the Sicily mummy project, highlighting unique challenges and major ethical concerns inherent to the scientific study, conservation, and presentation of these mummies. Recognizing mummies as a distinct category of human remains, this paper argues for the development and application of specialized guidelines that address the intricate balance between scientific inquiry and respect for the cultural, religious, and mortuary practices that characterize the cultural context, in this case of Sicily. Through a transparent and collaborative dialogue among all stakeholders-including curators, clergy, scientists, and government officials-the project ensures the preservation of the mummies\' dignity within their sacred spaces. The critical role of biological anthropologists is emphasized, alongside the contributions of clinical radiologists, pathologists, and qualified restorers, in constructing a comprehensive understanding of the mummies\' biocultural significance. The paper advocates for a bioarchaeological strategy that advances scientific knowledge while safeguarding the mummies and respecting living communities. Additionally, we call for ethical rigor in scholarly publications and suggest future actions to protect this invaluable heritage. This approach not only preserves the dignity and integrity of the mummified remains but also enriches our understanding of past human societies.

OBJECTIVE: To analyze the overall frequency and inter-tooth patterns of caries in three populations from ancient cemeteries located along the western border of the Central Iranian Plateau as a means to explore whether the populations of Iran had greater access to fermentable sugars after the establishment of the great empires.
METHODS: Dental collections from Kafarved-Varzaneh (Early Bronze Age, MNI=66), Estark-Joshaqan (Iron Age, MNI=57), Tappeh Poustchi (Timurid and Safavid Period, MNI=34), together with comparative data from NE Syria.
METHODS: Frequencies of dental caries per tooth categories, location and size of carious lesions are analyzed using Smith\'s Mean Measure of Divergence, Correspondence Analysis, χ2 and Kruskal-Wallis tests.
RESULTS: There are minimal differences in overall frequencies of carious lesions at Iranian sites, regardless of the chronology, but notable differences at Syrian sites. The inter-tooth pattern at the Iron Age cemetery in Estark appears distinctly different than the other Iranian sites and the comparative samples from Syria.
CONCLUSIONS: Divergent subsistence strategies may be linked with different inter-tooth patterns since people buried at Estark were mobile herders, while the other cemeteries were used by settled farmers.
CONCLUSIONS: This comprehensive research on dental caries in three chronologically diverse populations in Iran sheds light on the association between dental caries and subsistence strategies, and introduces the Smith\'s Mean Measure of Divergence to explore inter-tooth carious patterns, which may prove useful to other researchers seeking to understand the relationships between subsistence, diet, and the presence of carious lesions.
CONCLUSIONS: The studied sample size is relatively small and therefore its temporal/regional distribution produces low-resolution results.
UNASSIGNED: More systematic research on the patterns of dental caries is necessary to produce more fine-grained reconstructions of diet and subsistence in Iran and around the globe.

Over the last few decades, measurements of light stable isotope ratios have been increasingly used to answer questions across physiology, biology, ecology, and archaeology. The vast majority analyse carbon (δ13C) and nitrogen (δ15N) stable isotopes as the \'default\' isotopes, omitting sulfur (δ34S) due to time, cost, or perceived lack of benefits and instrumentation capabilities. Using just carbon and nitrogen isotopic ratios can produce results that are inconclusive, uncertain, or in the worst cases, even misleading, especially for scientists that are new to the use and interpretation of stable isotope data. Using sulfur isotope values more regularly has the potential to mitigate these issues, especially given recent advancements that have lowered measurement barriers. Here we provide a review documenting case studies with real-world data, re-analysing different biological topics (i.e. niche, physiology, diet, movement and bioarchaeology) with and without sulfur isotopes to highlight the various strengths of this stable isotope for various applications. We also include a preliminary meta-analysis of the trophic discrimination factor (TDF) for sulfur isotopes, which suggest small (mean -0.4 ± 1.7 ‰ SD) but taxa-dependent mean trophic discrimination. Each case study demonstrates how the exclusion of sulfur comes at the detriment of the results, often leading to very different outputs, or missing valuable discoveries entirely. Given that studies relying on carbon and nitrogen stable isotopes currently underpin most of our understanding of various ecological processes, this has concerning implications. Collectively, these examples strongly suggest that researchers planning to use carbon and nitrogen stable isotopes for their research should incorporate sulfur where possible, and that the new \'default\' isotope systems for aquatic science should now be carbon, nitrogen, and sulfur.
