Understanding the dynamics of sedimentary organic carbon (SOC) in the productive continental marginal sea surrounding Antarctica is crucial for elucidating the effect of this sea on the global carbon cycle. We analyzed 31 surface sediment samples and eight sediment cores collected from Prydz Bay (PB) and the adjacent basin area. The element and stable isotope compositions, grain size compositions, and biogenic silica and lithogenic minerals of these samples were used to evaluate the spatial variations in the sources, transport mechanisms, and preservation patterns of SOC, with a particular focus on the efficiency of the biological carbon pump (BCP). Our findings reveal that the SOC originated from mixed marine/terrestrial sources. The δ13C values were higher in the Prydz Bay Gyre (PBG) region than in the open sea area. Biogenic matter-rich debris, associated with fine-grained particles (silt and clay), was concentrated in the PBG, while abiotic ice-rafted debris and coarse-grained particles were preferentially deposited in the bank and ice shelf front regions. Lithogenic matter predominated in the basin sediments. The annual accumulation rate of SOC in PB ranged from 1.6 to 6.2 g·m-2·yr-1 (mean 4.2 ± 1.9 g·m-2·yr-1), and the rates were higher in the PBG than in the ice shelf front region. Estimates based on our tentative box model suggest that the efficiency of the BCP, which refers to the proportion of surface-produced organic carbon successfully transferred to deep waters, is approximately 5.7 % in PB, surpassing the global average (∼0.8 %) and the efficiencies reported for other polar environments. Furthermore, our calculations indicate that the SOC preservation efficiency (the ratio of preserved to initially deposited organic carbon in sediments) in PB is approximately 79 % ± 20 %, underscoring the significant carbon sequestration potential within PB. The results of this study have important implications for the effects of sediment dynamics on the carbon cycle in the sea surrounding Antarctica.

The Aven de la Boucle (Corconne, Gard, southern France) is a karst shaft used as a collective burial between 3600 and 2800 cal BCE. The site encompasses the skeletal remains of approximately 75 individuals comprising a large majority of adult individuals, represented by scattered and commingled remains. To date, few studies have explored the potential of ancient DNA to tackle the documentation of Neolithic collective burials, and the funerary selection rules within such structures remain largely debated. In this study, we combine genomic analysis of 37 individuals with archaeo-anthropological data and Bayesian modelling of radiocarbon dates. Through this multidisciplinary approach, we aim to characterize the identity of the deceased and their relationships, as well as untangle the genetic diversity and funerary dynamics of this community. Genomic results identify 76% of male Neolithic individuals, suggesting a marked sex-biased selection. Available data emphasize the importance of biological relatedness and a male-mediated transmission of social status, as the affiliation to a specific male-lineage appears as a preponderant selection factor. The genomic results argue in favour of \'continuous\' deposits between 3600 and 2800 BCE, carried out by the same community, despite cultural changes reflected by the ceramic material.

Microplastics (MP) are now present in all ecosystems and undergo weathering processes, including physical or chemical degradation. Although most studies have been carried out on MP toxicity in the marine ecosystem, interest is growing for the terrestrial and entire aquatic compartments. However, the interface between both environments, also known as the soil/water continuum, is given little consideration in MP toxicity studies. Only a few studies considered the toxicity of artificially aged or soil field-collected MP on species living at this interface. The present study evaluates the impact of artificial and field aging polyethylene (PE) MP on the bivalve Scrobicularia plana, a key organism of the estuarine compartment, living at the soil/water interface. Clams were exposed for 21 days to environmental concentrations (0.008, 10 and 100 μg L-1) of unaged as well as artificially and field aged PE MP. Toxicity was assessed from individual to molecular levels including condition index, clearance rate, burrowing behavior, energy reserves, enzyme activities and DNA damage. Results showed differential effects at all biological levels depending on the type and the concentration of the MP tested. Indeed, a decrease in burrowing behavior was observed in S. plana exposed to aged and field PE at low concentration (0.008 μg L-1). In the gills of clams, exposures to aged PE (0.008 and 100 μg L-1), virgin PE (10 μg L-1) and field PE (all tested concentrations) decreased CAT activity while DNA damage increased after exposure to virgin PE (0.008 μg L-1 and 10 μg L-1) and field PE (0.008 μg L-1). Our findings suggest that aging modifies the toxicity profile of PE polymer on S. plana and considering plastic from field at environmental concentrations is important when performing ecotoxicological studies.

In 2020, Denmark buried approximately four million culled, farmed mink in mass graves treated with slaked lime due to widespread SARS-CoV-2 infections. After six months, environmental concerns prompted the exhumation of these cadavers. Our analysis encompassed visual inspections, soil pH measurements, and gas emission assessments of the grave environment. Additionally, we evaluated carcasses for decay status, cadaverine content, and the presence of various pathogens, including SARS-CoV-2 and mink coronavirus. Our findings revealed minimal microbial activity and limited carcass decomposition. Although viral RNA from SARS-CoV-2 and mink coronavirus, along with DNA from Aleutian mink disease virus, were detected, the absence of infectious SARS-CoV-2 in cell culture assays suggests slow natural degradation processes. This study provides critical insights for future considerations in managing mass burial scenarios during outbreaks of livestock-associated zoonotic pathogens.

The meaning ascribed to death differs from one society to the other. This study adopts the descriptive method in unraveling the ritual of burial practices among the Ilaje people of Nigeria\'s Niger delta. Based on linguistic similarities, Ilaje people are part of the Yoruba ethnic group of Nigeria\'s Southwest area. Among the people, burial accorded to the dead is based on how the deceased died. The Ilaje groups death into five distinctive categories - death due to old-age, death caused by witchcraft or evil spirit, death through drowning by accident, death through curse, and death due to suicide. For the people, adult\'s death has two layers of meaning: sorrow and merriment. We conclude that physical death is viewed as part of the continuum of life\'s circle; it is the point when the dead pass to the realm of the ancestor who may be reborn into the family in the future.

The importance of ritual/ceremony following bereavement is well documented, however restrictions during the COVID-19 pandemic impacted the freedom to bury loved ones according to beliefs/traditions. This study explores the experiences of staff providing funeral services during COVID-19 and considers the implications for supporting bereaved families. Fifty-eight staff (male, 72.4%; n = 42) from 17 counties in Ireland, completed a self-report survey assessing perceived impact of COVID-19, confidence providing services, and challenges and supports for practice during this time. Quantitative findings suggest moderate confidence in service provision and low perception of negative impact from COVID-19, while qualitative results highlight a contrast between a feeling of under-recognition at a policy level and a sense of being appreciated by the public. This study highlights the evolving role of the funeral sector in Ireland in supporting the bereaved, and the potential to capitalise on a genuine interest in contributing more to support beyond the funeral.

More than 1200 civilians and military were killed in cities and villages by the Hamas attack on October 7th, 2023. The bodies and body-parts had to be identified and released for burial. This report outlines the challenges and mode of operation of the massive disaster victim identification (DVI) efforts. Bodies were delivered to a central mortuary. Each body was coded and undressed for external inspection and documentation of physical elements. Digital fingerprints were recorded and blood or toenails sampled for DNA. Odontology exams were performed by dentists describing dentition, aided by computerized tomography (CT). Whole-body CT was performed in cases the bodies were disfigured or burned from the second week. Simultaneously, families of missing civilians provided physical elements to the police to extract the DNA for antemortem documentation. The police took the responsibility over the reconciliation, which was based on comparison of the ante-mortem and post-mortem fingerprints, aided by DNA profile matching, odontology examination, clinical and/or radiological findings performed by forensic practitioners. Secondary identification elements were used assure the families regarding the identification. Precise scientific identification a was a priority, even if it slowed the rate of bodies release. Families were allowed to view their relative either at the mortuary or before burial. The DVI process required cooperation between several governmental agencies and police. To maximize the effectiveness, a synchronized approach should be adopted, specifying communication channels between the partners and dividing the responsibilities. The DVI should be led by a single, experienced authority to ensure interdisciplinary teamwork. This catastrophe required personal resilience of the teams for rapid and efficient functioning and communication between the partners.

Microplastic deposition in soft marine sediments raises concerns on their role in sediment habitats and unknown effects on resident macrobenthic communities. To assess the reciprocal influence that MPs and macrobenthos might have on each other, we performed a mesocosm experiment with ambient concentrations of environmental Polyethylene (PE) and a non-manipulated, natural macrobenthic community from the Belgian part of the North Sea (BPNS). Our results show that PE fragments increase mortality of abundant bivalves (specifically Abra alba) after 30 days of exposure but not for the most abundant polychaete Owenia fusiformis, possibly due to its predominant suspension feeding behavior. Fast burial of surface MPs exposes deep-dwelling burrowers to the pollutant, however reducing the amount of MPs interacting with (sub) surface living fauna. We conclude that macrobenthos promotes the sequestration of deposited MPs, counteracting resuspension, and can have cascading effects on biodiversity due to their effect on abundant and functionally important species.

UNASSIGNED: Cadaveric identification represents a legal, moral and medico-legal obligation and also fulfills the ethical function to allow the living to offer their dead a merciful burial. In the Mediterranean basin we have been witnessing for years a struggle for life where hundreds of migrants die in an attempt to reach Europe. For these people right to be recognized is not easy because of ante-death biological data are not always available for comparison, and DNA analysis is not always feasible cause for the absence of data with which to compare. In Italy a multidisciplinary protocol has been adopted that involves the acquisition of data provided by family members present in the countries of origin.
UNASSIGNED: Between August 2015 and December 2021, bodies of 879 migrants of various nationalities washed up on the shores of Sicily and Calabria. These men, women, and children, in various states of preservation, were examined. Each body underwent a multidisciplinary approach. External examination and autopsy aimed to determine the cause of death for judicial purposes and to facilitate individual identification. Whenever possible bodies underwent total body post-mortem computed tomography examination to identify fractures and prosthetic implants. including inspection of the third molar to provide an estimate of the age.
UNASSIGNED: The activity carried out in cooperation with Prefecture, Scientific Police, and National and International Red Cross highlighted the importance of employing multiple scientific skills to compensate for the lack of biological information. The importance of appropriate behaviors to avoid contamination and ensure proper preservation underlines the importance of the establishment of a dedicated database.

UNASSIGNED: Upper extremity sensory neuromas can be extremely debilitating leading to pain and dysfunction. Surgical management of neuromas can either be ablative or reconstructive. The primary aim of this study was to examine the outcomes of surgically treated sensory neuromas within the forearm, wrist, and hand with exclusion of digital neuromas.
UNASSIGNED: A retrospective review was conducted of patients surgically treated for an upper extremity sensory neuroma from a multi-surgeon, single institution database. The types of neuroma, mechanism of injury and the surgical technique utilized for treatment were documented. Patient reported outcomes were collected including resolution of symptoms, pain scores, complications, and need for revision surgery. Averages and proportions were used for analysis.
UNASSIGNED: 79 patients were included with mean age of 42.3 years and an average follow-up of 6.7 months. The types of sensory neuromas included 23 dorsal radial sensory, 21 medial antebrachial cutaneous, 15 palmar cutaneous, and 14 dorsal ulnar sensory. Single isolated cases of neuromas were more common (94.9%) than multiple neuromas (5.1%). 67.1% (53/79) of patients experienced pain or hypersensitivity with a mean improvement of 2.0 in the visual analog scale (VAS) following surgery. 6.3% (5/79) required revision surgery, and 82% returned to work in some capacity.
UNASSIGNED: Surgical excision of neuroma and burial into local surrounding tissue can be safely performed with a relatively low reoperation rate. 80% of patients had full resolution or improvement in their symptoms.
