    Impact of the scale-up of piped water on urogenital schistosomiasis infection in rural South Africa

    Frank Tanser et al.
    Scale-up of safe water supplies decreases a child's risk of urogenital schistosomiasis infection by eight-fold in a typical rural African population.

    Ancient DNA reveals the lost domestication history of South American camelids in Northern Chile and across the Andes

    Paloma Diaz-Maroto et al.
    aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.

    Homo naledi, a new species of the genus Homo from the Dinaledi Chamber, South Africa

    Lee R Berger et al.
    A new hominin species has been unearthed in the Dinaledi Chamber of the Rising Star cave system in the largest assemblage of a single species of hominins yet discovered in Africa.

    A single clonal lineage of transmissible cancer identified in two marine mussel species in South America and Europe

    Marisa A Yonemitsu et al.
    A transmissible cancer that arose in a marine mussel spread from a single animal to become a global pathogen affecting two other mussel species in both Europe and South America.

    Geological and taphonomic context for the new hominin species Homo naledi from the Dinaledi Chamber, South Africa

    Paul HGM Dirks et al.
    A new hominin species found in a South African cave is part of one of the most unusual hominin fossil assemblages on record.

    New fossil remains of Homo naledi from the Lesedi Chamber, South Africa

    John Hawks et al.
    The discovery of new skeletal remains of Homo naledi in the Lesedi Chamber, South Africa, adds more evidence to our understanding of the morphology and behavior of this recently discovered species.

    Impact of community piped water coverage on re-infection with urogenital schistosomiasis in rural South Africa

    Polycarp Mogeni et al.
    Scale-up of piped water coverage in the local community strongly protects against S. haematobium re-infection intensity among primary school-going children following treatment with praziquantel.

    The age of Homo naledi and associated sediments in the Rising Star Cave, South Africa

    Paul HGM Dirks et al.
    Independent dating techniques have established that the H. naledi fossils are between 236 and 335 thousand years old, indicating that small-brained hominins with relatively primitive body shapes co-existed with our early ancestors in Africa.

    A mechanistic model for long-term immunological outcomes in South African HIV-infected children and adults receiving ART

    Eva Liliane Ujeneza et al.
    Long-term immune outcomes vary with age, for both adults and children in HIV-infected populations, e.g. long-term scaled carrying capacity is lower in HIV-infected younger individuals compared to older individuals.

    Immune-mediated hookworm clearance and survival of a marine mammal decrease with warmer ocean temperatures

    Mauricio Seguel et al.
    In years with colder ocean temperatures, fur seal pups receive more maternal care and have a better energy balance, clearing hookworm infection earlier, which increases their chances of survival.
