This paper describes a study on participant engagement and feedback in microbiome projects in Africa, finding that culturally appropriate and timely feedback can improve trust and motivate health behaviors.

This study expands the human gut microbiome atlas of Africa by analyzing 1,803 women from four countries, revealing geographic and lifestyle-associated taxa and novel microbial genomes.

This paper presents a blood regulatory variation map from Southern African populations, showing increased utility for interpreting African genetic studies.

This study conducts a GWAS on urinary albumin-to-creatinine ratio in Sub-Saharan African and non-resident African-ancestry populations, identifying two genome-wide significant loci and highlighting limited transferability of polygenic scores across populations.

This study investigates genetic substructure and demographic history of South African Bantu speakers using genome-wide data, revealing fine-scale population structure aligned with geography and linguistics.

This study uses short- and long-read metagenomics to analyze gut microbiomes in South African populations, revealing intermediate composition and novel taxa not captured by existing reference databases.
