Insights into South African population history from 10,000-year-old human DNA

Researchers analyzed ancient genomes from the Oakhurst rock shelter in southern Africa, finding that the oldest genomes are genetically similar to San and Khoekhoe groups living today. The study reveals a long history of relative genetic stability until around 1,200 years ago when newcomers introduced new cultures and languages.

Iron given through the vein corrects iron deficiency anaemia in pregnant women faster and better than iron taken by mouth

A recent clinical trial found that an IV iron treatment called ferric carboxymaltose works faster and better than oral iron tablets in treating anaemia during pregnancy. The study showed improved haemoglobin levels and iron correction with the IV treatment, with comparable side effects.

South African rock art possibly inspired by long-extinct species

A study published in PLOS ONE suggests that South African rock art from the 19th century may be inspired by an extinct species of tusked animal called a dicynodont. The artwork, created by the San people, features a long-bodied animal with downward-turned tusks that is comparable to fossilized remains found in the region.

Rising temperatures in Africa may increase perinatal deaths

A study published in Nature Medicine reveals a correlation between high temperatures in the final week of pregnancy and an increased risk of stillbirth and early neonatal mortality. High temperatures were associated with a 34% higher risk of perinatal death, which doubled during the six hottest months of the year.

Lackluster prioritization of the health sector in government spending and dwindling donor contributions drive slow growth in health spending in Sub-Saharan Africa

A study published in PLOS Global Public Health finds that slow growth in health sector spending is projected in Sub-Saharan Africa until 2050. The decline is driven by tepid growth in government spending and reductions in development assistance for health.

Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water

Research reveals that deforestation in Africa's montane forests has induced a higher warming and cloud level rise than climate change alone, leading to decreased water supply. The study found that air temperature increased by 1.4°C and cloud levels rose by 230 meters over the last 20 years.
