African livestock producers have a unique opportunity to improve the production of meat, milk and eggs through modern breeding technologies and innovations being tested in Africa, according to a recent study published in Nature Genetics. With the right support, these advancements can enhance not only productivity but also climate resilience and sustainability.
The paper, titled, Expanding the human gut microbiome atlas of Africa, was published today in Nature, the world’s leading scientific journal.
The gut microbiome has a significant impact on human health, and the lack of knowledge of the diversity of microbiomes in Africa has been a barrier to future health interventions and research.
The study is a critical development in gut health research globally as much more can now be learned, particularly about diseases such as cancer, diabetes, and obesity, and their relationship to gut microbiota.
A major new book on the ecology and management of one of the most destructive invasive weeds in Africa, is now available online.
The book, titled The Ecology and Management of Invasive Prosopis Trees in Eastern Africa, is the outcome of a large, decade-long collaborative research project, involving six universities and eight institutes from Ethiopia, Kenya, Tanzania, South Africa, Switzerland, and the United States of America (USA).
Human ancestors like Australopithecus – which lived around 3.5 million years ago in southern Africa – ate very little to no meat, according to new research published in the scientific journal Science. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on plant-based diets, with little to no evidence of meat consumption.
Physicists from the University of the Witwatersrand (Wits) have developed an innovative computing system using laser beams and everyday display technology, marking a significant leap forward in the quest for more powerful quantum computing solutions.
In the largest systematic review of its kind, we reviewed 198 studies that assessed the impact of heat on maternal, fetal, and neonatal health, across 66 countries.
We found that for every 1°C increase in heat exposure, there was a 4% increase in odds of preterm birth across all the studies. During a heatwave, the odds of preterm birth increased by 26%. Similarly, we found marked increases in other adverse outcomes such as increased risk for gestational diabetes, stillbirths, congenital anomalies and obstetric complications with increasing exposure to heat. There is limited research on outcomes like antenatal bleeding and caesarian section risks that may be related to heat exposure and could contribute significantly to morbidity and mortality.
“Our research provides compelling evidence that heat exposure poses severe health risks for pregnant women and their babies, yet these risks are frequently underestimated”, said Prof. Matthew Chersich, executive director at Wits Planetary Health Research.
