Armed with water tests, SA students tackle eco-anxiety
After wading back to the river bank, Downsborough poured her findings into a container to identify the different macroinvertebrates with the help of her students.
Each organism was given a unique score under the mini stream assessment scoring system (miniSASS) to help determine the water quality. The final results will be uploaded to an online map to identify polluted sites.
Downsborough and her team also encourage citizen scientists to try out other water testing kits, such as Freshwater Watch and WaterCAN, which test for a range of pollutants such as excessive nitrates and phosphates.
Findings can be uploaded online to be used by activists to rally for government action.
In April, WaterCAN, alongside other civil society organisations, launched a report on Durban's Umbilo River that revealed pollution, including high levels of E coli bacteria.
They called for urgent infrastructure repairs based on their findings.
'Civil society must continue to push for accountability, create awareness in communities and build action through citizen science,' the report said.
The eThekwini municipal water and sanitation department acknowledged receipt of questions regarding the report, but did not respond to a request for comment by the time of publication.
GroundTruth, an environmental consulting company that helped develop the miniSASS kit, trains citizen scientists including more than 1,000 youth in KwaZulu-Natal.
Downsborough and Stippel presented their research on public participation at the Citizen Science for Water Quality Conference in the Netherlands in early June. Next year, the IIE MSA water monitoring initiative will be expanded more widely across campuses and schools.
'Writing papers is one way to have impact, but bringing students outdoors to the river, bringing our office out to the river, is very rewarding,' Downsborough said.

Groundbreaking study finds new genes in black women causing breast cancer
All participants were from the Soweto region, with 2,485 population cases and 1,101 control cases. The South African BC cases and controls were well-matched and clustered, while the non-South African samples and West African populations were distinct from South African populations. The Genome-Wide Association study (Gwas), which is the first to focus on black women on the continent, was published in the journal Nature Communications . It brings to the fore the importance of deepening knowledge about the genetic basis of the disease. In the past, most breast cancer genetics research has focused on European and Asian populations, with studies of African ancestry limited primarily to African-American women, who largely descend from West African populations. A tool that estimates lifetime cancer risk based on DNA, the polygenic risk score (PRS), performed poorly in distinguishing South African women with breast cancer from those without. Dr Jean-Tristan Brandenburg, also in the SBIMB and a lead author, said this was a result of the mechanism not being tailored for the black population. 'This is because most PRSs were developed in European populations, and their inaccuracy in African populations highlights the urgent need for ancestry-specific tools in cancer risk prediction,' Brandenburg said. African populations have more genetic variation than any other population in the world, but they have been significantly underrepresented in genomic research. This means the global understanding of disease risk and the tools and treatment developed from it are limited. 'The study reveals that more people can benefit from genetic discoveries. It proves that new risk factors are still out there, waiting to be found,' says Hayat. TimesLIVE

New species of rain frog discovered in SA
Breviceps batrachophiliorum. In the damp, grassy slopes of the KwaZulu-Natal Midlands, an unassuming amphibian has leapt into the scientific spotlight. Named Breviceps batrachophiliorum – Latin for 'frog-loving people' – this newly described species of rain frog is a triumph of taxonomy and a compelling example of the intersection of citizen science and academic rigour. Professor Louis du Preez of the North-West University (NWU) led the discovery, drawing on his long and distinguished career as a herpetologist. The breakthrough came thanks to three passionate frog enthusiasts: Nick Evans, Dylan Leonard and Cormack Price. They set out on a mission to spot and document every frog in Prof du Preez's field guide. One night, after some heavy rain, they set out to find the elusive Bilbo's rain frog (Breviceps bagginsi), named after Bilbo Baggins, from The Lord of the Rings, who also lived in a hole in the ground. When they found what they believed to be a Bilbo's rain frog, they sent a photograph and an accompanying call recording to Prof du Preez. 'There was something curious,' recalls Prof du Preez. 'I thought they had mixed up the images and the sounds. But when I pointed this out, they sent a video, and that's when I realised that we were looking at a new species.' What followed was a meticulous analysis process, detailed in the African Journal of Herpetology. The team employed an integrative approach, blending morphology, genetics and, crucially, bioacoustics. The frog's call, a vital identifier in such a visually cryptic genus, diverged sharply from those of its closest relatives. Genetically, it showed a 7.5% difference in mitochondrial 16S rRNA compared to Breviceps verrucosus. This clear signal indicated that this frog was not only new to science, but also worthy of its own species status. Though short-limbed, round-bodied and earth-toned, B. batrachophiliorum is far from plain. Its eardrum is unusually visible, a rare feature among its kin, and the position of its mouth sets it apart from B. verrucosus. In acoustic terms, its calls are shorter, faster and more frequent than those of similar species. Such subtleties are crucial in frog courtship and therefore in species recognition. Prof du Preez and his co-authors, EC Netherlands and LR Minter, also stress the importance of this discovery for conservation. With an occupancy area of just 1 108 km², this frog's habitat is largely restricted to three types of mistbelt grassland in the KwaZulu-Natal Midlands. Although some populations occur within protected areas such as the Clairmont Nature Reserve, the species' limited range raises concerns about its vulnerability to habitat destruction and climate change. This tale is about more than just taxonomy. It is also a cautionary tale about the fragility of ecological knowledge. The new frog was once misidentified as Bilbo's rain frog (Breviceps bagginsi), a mistake with far-reaching consequences. The description of the new species means that Bilbo's rain frog is now only known to exist in one population in a highly transformed area, and as a result, its conservation status jumped to critically endangered. With the correction in place, the true distribution range of both species can be assessed more accurately. This is a small but vital victory for conservation science. Importantly, the discovery highlights a broader trend. Since 2000, over a third of Breviceps species have been described, a surge largely driven by advances in molecular biology and acoustic analysis. South Africa, with its rich and still unfolding biodiversity, is at the heart of this amphibian renaissance. Ultimately, Breviceps batrachophiliorum is more than just another new name in a long list. It serves as a reminder that discovery still hides in plain sight, and that with enough passion, patience and a bit of rain, even the quietest calls can be heard. • Follow the link to the article here:
