An international collaboration of conservation, environment, and human development experts and practitioners led by the United Nations Development Program’s Human Development Report Office (UNDP-HDRO) proposes a new way for countries to measure and improve their relationships with nature and each other.

The newly launched South African Blood Regulatory (SABR) dataset reveals how genetic variation influences blood traits and gene activity in African populations, providing crucial insights into diseases like diabetes and heart disease.

This means researchers can now use the resource to better predict who is at risk, why specific populations respond differently to treatments, and how to develop more effective, tailored interventions.

With African populations historically underrepresented in genomic research, SABR marks a significant step toward more inclusive and more accurate precision medicine.

Messenger RNA (mRNA) vaccine technology, which rose to prominence during the Covid-19 pandemic, is now being repurposed by South African scientists to tackle one of the world’s oldest infectious diseases—tuberculosis.

At the Wits Antiviral Gene Therapy Research Unit (AGTRU), Dr Kristie Bloom leads efforts to develop a locally produced mRNA-based TB vaccine. Unlike traditional vaccines, which rely on weakened viruses, mRNA vaccines deliver genetic instructions that prompt the body to produce a harmless piece of the virus, training the immune system to respond.

This technology offers speed, adaptability, and potentially stronger immune responses. "We can manufacture mRNA vaccines rapidly and adjust them easily if pathogens mutate or emerge," says Bloom.

In collaboration with the South African Tuberculosis Vaccine Initiative (SATVI) at the University of Cape Town, AGTRU is advancing two TB vaccine candidates. These vaccines aim to trigger the T-cell responses needed to overcome Mycobacterium tuberculosis, a pathogen responsible for 56,000 deaths in South Africa in 2023 alone.

Researchers believe that a successful vaccine could prevent up to 76 million TB cases and save 8.5 million lives over 25 years. “This isn’t just about innovation—it’s about self-reliance and equity in global health,” Bloom says.

New research from the Future Ecosystems for Africa program at the University of the Witwatersrand in South Africa, has created the most accurate maps yet of where reforestation can effectively combat climate change.

The study identifies 195 million hectares globally where tree restoration will deliver maximum climate benefits without harming communities or ecosystems.

The study, published in Nature Communications and drawing from 89 previous research projects, provides the most comprehensive mapping yet of areas where reforestation can deliver optimal climate benefits while supporting wildlife habitat, food production, and freshwater availability.

A new species of velvet worm, Peripatopsis barnardi, represents the first ever species from the arid Karoo, which indicates that the area was historically more forested than at present. In the Cape Fold Mountains, we now know that every mountain peak has an endemic species. This suggests that in unsampled areas there are likely to be additional novel diversity, waiting to be found.

New research from the University of the Witwatersrand in Johannesburg, South Africa, has revealed that puff adders (Bitis arietans) can be highly efficient at controlling rodent populations that threaten agricultural production on the continent. 

The Antiviral Gene Therapy Research Unit (AGTRU) and the Synthetic Organic Chemistry Unit in the School of Chemistry at Wits have received one of six international innovation awards under the GIZ SAVax programme. Their project, Local large-scale production of ionisable lipids, secured a R7-million grant to develop vaccine-enabling compounds derived from cashew nutshell liquid – a by-product of the cashew industry that is abundant across Africa.

This breakthrough positions Wits and South Africa as a leader in developing bio-renewable materials for mRNA vaccines and supports the African Union’s target of producing 60% of the continent’s vaccines locally by 2040. Currently, Africa produces only 1% of the vaccines it uses.
