Exploration of the Medici chapels in San Lorenzo in Florence revealed the burials of nine infantile members of the Medici family. Eight children were found in the intact tomb of the last Grand Duke Giangastone (1671- 1737). The crypt contained several small coffins collapsed to the floor or randomly spread over a raised plank, as a result of the disastrous flood of the Arno river in 1966, which partly upset the tomb and left a layer of dry mould. The children's remains, mostly skeletonised, were found inside the coffins or scattered on the floor or on the plank, probably transported by the water. Another child was exhumed from the chapel of Grand Duke Ferdinand I (1549-1609) and Cristina from Lorena (1565-1636). The infantile remains were submitted to anthropological study, which allowed to establish the number of individuals buried in the crypt, and to estimate the age at death. The anthropological results were compared with information provided by archival documents, related to members of the family who died in infantile age. An identification of the children is proposed.

There is concern over potential toxic elements (PTEs) impacting river ecosystems due to human and industrial activities. The river's water, sediment, and aquatic life are all severely affected by the release of chemical and urban waste. PTE concentrations in sediment, water, and aquatic species from river ecosystems are reported in this review.

This article aims to illustrate the pivotal role that the environment plays in early child development (ECD), drawing upon data derived from the ethnographic research on children's daily routines. Participant observation and in-depth interviews were conducted over the course of several fieldwork periods (2013-2018). The concept of "mutual raising" is employed to examine the daily interactions between middle-aged children and their domestic animals.

Despite the advances in paleogenomics, red cell blood group systems in ancient human populations remain scarcely known. Pioneer attempts showed that Neandertal and Denisova, two archaic hominid populations inhabiting Eurasia, expressed blood groups currently found in sub-Saharans and a rare "rhesus", part of which is found in Oceanians. Herein we fully pictured the blood group genetic diversity of 22 Homo sapiens and 14 Neandertals from Eurasia living between 120,000 and 20,000 years before present (yBP).

Background: The advancements in second-/third-generation sequencing technologies, alongside computational innovations, have significantly enhanced our understanding of the genomic structure of Y-chromosomes and their unique phylogenetic characteristics. These researches, despite the challenges posed by the lack of population-scale genomic databases, have the potential to revolutionize our approach to high-resolution, population-specific Y-chromosome panels and databases for anthropological and forensic applications.
Objectives: This study aimed to develop the highest-resolution Y-targeted sequencing panel, utilizing time-stamped, core phylogenetic informative mutations identified from high-coverage sequences in the YanHuang cohort.

In vertebrates, glucocorticoids can be upregulated in response to both psychosocial and energetic stressors, making it difficult to identify the cause of elevated glucocorticoid concentrations when both types of stressors are present. This problem has been particularly challenging in studies of social dominance rank in wild animals. In contrast to glucocorticoids, thyroid hormone concentrations are largely unaffected by psychosocial stressors and therefore offer a better estimate of energetic challenges.
