The archaeology and history of the Red Sea area of eastern Sudan during the Medieval period has been receiving increased attention in recent years. This paper reviews the observations of the recent archaeology and landscape surveys and integrates them with the ongoing work undertaken by The Suakin and the Red Sea Project for Archaeological Environmental and Cultural Studies directed by Ahmed Adam and undertaken by the Department of Archaeology, University of Khartoum. To date, important information has been uncovered by the expedition relating to the earliest Medieval occupation and the forms and impact of Islamic trade activity. The majority of the new data come from Suakin, 'Aydhâb (Aidab) and Badi', principal ports along the Sudanese Red Sea coast that played a major role in this trade. Previously, little was known about the area beyond these ports. The work done by the expedition so far lays the foundation for future field seasons to better understand long-term human settlements during the Medieval period of eastern Sudan by integrating archaeological surveys with excavations and oral histories.

Background The Erythrocyte Binding Antigen (EBA) 175 has been considered as one of the most important Plasmodium falciparum (P. falciparum) merozoite ligands that mediate invasion of the erythrocytes through their sialated receptor: Glycophorin A (GPA). The effect of the EBA 175 dimorphic alleles (F and C) on the severity of the disease is not yet fully understood. Therefore this study was designed to assess the distribution of the divergent dimorphic alleles of P. falciparum EBA-175 (F and C) in three different geographical areas in Sudan and the possible association of this dimorphism with the severity of the disease. Methods A sum of 339 field isolates of P. falciparum obtained from patients in three different geographical areas in Sudan were screened for the dimorphic alleles (F, C) of the EBA-175 using nested PCR. Results The percentage of F, C, and mixed F/C alleles were; 41%, 51%, and 8% respectively. F and C alleles showed significantly different distributions in the various geographic areas (p = 0.00). There was no significant association between malaria clinical manifestation and P. falciparum EBA-175 F and C alleles frequencies Conclusions This study showed a significant differential distribution of F and C alleles in different geographical malaria endemic areas. No significant association was observed between F and C alleles and different malaria phenotypes. [ABSTRACT FROM AUTHOR]

The site of Jebel Moya, situated in the center of the southern Gezira Plain in southcentral Sudan, has an occupational sequence spanning at least five millennia until around 2000 years ago. Renewed excavation is shedding new light on its occupational chronology and socioeconomic history, including activities such as burial, savanna herding, and domesticated sorghum cultivation practices dating to at least the mid-third millennium BC. In the present study, predominantly final phase pottery sherds from the first millennium BC to the start of the first millennium AD (Assemblage 3) have been analyzed via a combination of thin section petrography and instrumental geochemistry to determine their raw materials and place of manufacture and reconstruct their manufacturing technology. Organic residue analysis was also conducted to identify the products processed within vessels found at the site. The results suggest the existence of a well-developed local ceramic craft tradition that persisted for over one thousand years. Pots from Assemblage 3 were used to process, store, and consume animal and plant products, thus reinforcing emerging evidence for early agro-pastoral activities. [ABSTRACT FROM AUTHOR]

This paper presents new excavation data and new radiometric dates for Jebel Moya, south-central Sudan. These data suggest revisions to previous chronological understandings of the site. New excavations, initiated in 2017, show a longer, more continuous occupation of the site than has been previously recognised. Archaeozoological and archaeobotanical analyses provide evidence for domesticated taxa. Archaeobotanical evidence is dominated by domesticated sorghum (Sorghum bicolor), radiocarbon dated to c. 2550–2210 BC. Faunal remains include cattle and goat/sheep. A late third-millennium BC date on the human skeleton excavated in the 2017 season also shows that mortuary activity began early in the site's history, contemporary with domesticated faunal and botanical remains. These initial results indicate the long-term association of the site with pastoralism and agriculture and with environmental change. Jebel Moya's continued potential to serve as a chronological and cultural reference point for future studies in south-central Sudan and the eastern Sahel is reinforced. [ABSTRACT FROM AUTHOR]
