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.

Elon Musk's dream of colonising Mars suffers fiery setback
One of Elon Musk's SpaceX Starships exploded during a routine test late on Wednesday in Texas, law enforcement said, in the latest setback to the billionaire's dream of turning humanity into an interplanetary species. The Starship 36 suffered 'catastrophic failure and exploded' at the Starbase launch facility shortly after 23:00, a Facebook post by the Cameron County authorities said. A video shared with the post showed the megarocket attached to the launch arm, and then a flash and a towering, fiery explosion. Elon Musk's Space X said the rocket was preparing for the 10th flight test when it 'experienced a major anomaly while on a test stand at Starbase,' without elaborating on the nature of the complication. 'A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,' Space X added on social media. 'There are no hazards to residents in surrounding communities, and we ask that individuals do not attempt to approach the area while safing operations continue.' The Starship was not scheduled for launch on Wednesday evening when the explosion occurred during a 'routine static fire test,' according to the Cameron County authorities. During a static fire, part of the procedures preceding a launch, the Starship's Super Heavy booster would be anchored to the ground to prevent it from lifting off during the test-firing. Starbase on the south Texas coast, near the border with Mexico, is the headquarters for Musk's space project. Standing 403 feet (123 metres) tall, Starship is the world's largest and most powerful rocket and central to Musk's long-term vision of colonising Mars. The Starship is billed as a fully reusable rocket with a payload capacity of up to 150 metric tons. The latest setback follows an explosion of a prototype Starship over the Indian Ocean in late May. The biggest and most powerful launch vehicle ever built had lifted off on May 27 from the Starbase facility, but the first-stage Super Heavy booster blew up instead of executing its planned splashdown in the Gulf of Mexico. The previous two outings also ended poorly, with the upper stage disintegrating over the Caribbean. But the failures will likely do little to dent South Africa-born Elon Musk's spacefaring ambitions. SpaceX has been betting that its 'fail fast, learn fast' ethos, which has helped it dominate commercial spaceflight, will eventually pay off. The company has caught the Super Heavy booster in the launch tower's giant robotic arms three times — a daring engineering feat it sees as key to rapid reusability and slashing costs. NASA is also increasingly reliant on SpaceX, whose Dragon spacecraft is vital for ferrying astronauts to and from the International Space Station. The Federal Aviation Administration (FAA) in early May approved an increase in annual Starship rocket launches from five to 25, stating that the increased frequency would not adversely impact the environment. The decision overruled objections from conservation groups who had warned the expansion could endanger sea turtles and shorebirds.

Exploring new paths in tackling the big three infectious diseases
Prof Joe Viljoen. Just a few drops of oil and water may be enough to change how the world treats tuberculosis, malaria and HIV/Aids – the 'big three infectious diseases', also known as BTIDs. This was the central message delivered by Prof Joe Viljoen during her inaugural lecture at the North-West University's (NWU's) Potchefstroom Campus on 13 June 2025. Prof Viljoen, from the Faculty of Health Sciences, presented her work under the title: 'Combating the BTIDs using innovative self-emulsification drug delivery systems.' Her lecture focused on how self-emulsifying drug delivery systems (SEDDSs) can improve treatment for TB, malaria and HIV/Aids. 'These diseases are mostly treated with drugs that are highly lipophilic (water insoluble),' explained Prof Viljoen. 'That makes them difficult to absorb, especially for patients who are malnourished and unable to take the high-fatty meals required for proper drug uptake.' Harnessing the body's natural movement SEDDSs are oil-based formulations combined with surfactants and co-surfactants. Once swallowed or applied to the skin, they mix with the body's fluids and form fine emulsions without the need for external mixing equipment. 'With just the body's natural movement, for example, peristalsis in the stomach, SEDDSs form into very small droplets that help drugs dissolve and be absorbed more effectively,' she said. These delivery systems further improve bioavailability by enabling drugs to bypass the liver's first-pass metabolism through lymphatic transport. For skin-based applications, Prof Viljoen explained the importance of choosing oils that help the drug pass through the skin where water is limited. 'We have to carefully balance the oily and water-loving components. Natural oils are key, as they help the drug penetrate the skin barrier and are better accepted by consumers due to being viewed as safer.' Challenges in developing SEDDSs include selecting the correct ingredients, ensuring stability and controlling droplet size to regulate drug release. Tools such as pseudoternary phase diagrams help design fixed-dose combinations, especially where drugs have different solubility characteristics. 'These systems are scalable, stable and can be produced at relatively low cost,' said Prof Viljoen. 'They could make a significant difference in the treatment of infectious diseases, particularly in low-resource settings.' The lecture concluded with a call for interdisciplinary efforts to advance the development of SEDDS-based therapies.

‘Pupils taught in mother tongue comprehend better, are more confident'
The Eastern Cape provincial government says it is making strides in addressing literacy challenges among schoolchildren through its Mother Tongue-based Bilingual Education initiative. In 2012, the pilot programme was rolled out at 70 schools in the Cofimvaba district, where mathematics, natural science and technology were taught and assessed in both English and isiXhosa. Education department communications director Vuyiseka Mboxela said within four years, officials noted an improvement in the results of participating schools, and the programme was extended to all 12 education districts. 'The Cofimvaba pilot project reveals that when a home language is used, learners perform better cognitively and in subject content. 'A Xhosa-speaking learner also learns English as a second language easily if the home language skills are maintained,' she said. Phase one of the MTbBE project, which focuses on extending mother tongue instruction beyond grade 3 into grade 4, initially targeting mathematics and natural science and technology, has been rolled out to grade 4, at 1,455 schools across all 12 districts. The second phase, which includes classes up to grade 7, has been rolled out at 2,277 schools. Today, learning isiXhosa or SeSotho as an additional language is compulsory up to grade 4. In January, basic education minister Siviwe Gwarube said international benchmarking studies (including Trends in International Mathematics and Science and the Southern and Eastern Africa Consortium for Monitoring Educational Quality) as well as the department's Systemic Evaluation results showed that pupils in grades 5 to 9 significantly underperformed in relation to their global counterparts in mathematics and science. 'They also show that too many of our learners cannot read for meaning in any language by grade 4,' Gwarube said. Mboxela said the Eastern Cape was the only province to provide mathematics and natural sciences lessons and teaching plans in isiXhosa and Sesotho for grades 4 to 7, with the aim of improving results. Tool kits are available on the department's website for easy access to teachers. 'Mathematics and natural science and technology workbooks for grades 4 to 7 were versioned and edited in isiXhosa and Sesotho with new orthographic rules [spelling and writing rules] in both languages affected. 'This initiative assisted learners to be able to spell, write and read with meaning in their home languages,' Mboxela said. She said according to a test done in 2019, grade 6 pupils writing in isiXhosa achieved an average of 78% while their English counterparts averaged 40%. Other milestones since the inception of the programme 13 years ago include: The mother tongue learning programme has been rolled out in some form at 3,732 schools; 4,214 mathematics, science and technology teachers have received training; and 85,620 grade 12 pupils have had access to bilingual question papers in maths, life science, physical science, agricultural science, history and accounting. 'Furthermore, the department is implementing Incremental Introduction of African Languages in 121 former model C and private schools, with the view to teaching isiXhosa and Sesotho as first additional language or second additional language levels to English and Afrikaans learners, promoting nation-building, social cohesion, multilingualism and multiculturalism,' Mboxela said. In light of the success of Mother Tongue-based Bilingual Education in the Eastern Cape, former basic education minister Angie Motshekga announced last year that the programme would be rolled out to grade 4s at all SA schools. Addressing a language and literacy workshop, Motshekga said: 'It is time that we pay attention to what is taught in the curriculum and in which languages is it taught; to whom and whether it is making a positive difference to their learning trajectories. 'If it needs to be relooked and strengthened; a curriculum-strengthening process must address such a gap.' Mvuzo Primary School in Cofimvaba was among the first 70 schools to pilot the MTbBE initiative 13 years ago. Principal Mphuzi Mqombothi said the programme's rollout did not come without its challenges. He said there was a significant backlash, with parents opting to move their children to schools with English-only instruction. 'It was not easy; teething problems arose as teachers struggled with the new method. 'The shift from English-only instruction to bilingual teaching in isiXhosa and English posed challenges, particularly with science terminology and resource availability. 'Despite these hurdles, we've persisted. Yet, the preference for English remains strong, especially in public primary schools. 'Though the MTbBE is a beautiful and transformative programme aimed at decolonising education and enhancing literacy and comprehension among learners, many parents in the community still believe in the superiority of English and view the use of Xhosa as a downgrade in educational quality.' Despite the misperception of mother tongue learning, Mqombothi said, the switch to teaching and learning in English and isiXhosa had borne fruit at Mvuzo Primary. 'We have observed that even within MTbBE, there has been a significant improvement in English proficiency. 'Learners participating in MTbBE not only exhibit better comprehension of the subject matter but also speak better English, show increased innovation, possess greater self-confidence and engage more effectively than many others not enrolled in MTbBE.' Mqombothi said teachers had observed an improvement in the results of pupils who were previously underperformers. LF May Primary School in Qonce (formerly King William's Town) introduced isiXhosa learning in natural science and technology for grade 4 pupils last year. Principal Gcobani Sulo said: 'We were trained last year and had a workshop this year. But we are only doing grade 4. 'Grades 5, 6 and 7 will be introduced to the programme in the coming years. Our learners are improving, but parents still have attitudes towards this method of teaching; they want English.' University of Fort Hare department of languages and literacy interim head Dr Sive Makeleni said: 'The Eastern Cape has proven that learners who learn through their mother tongue perform exceptionally well, including those who learn in African indigenous languages. Hence, the department of basic education has taken this approach.' He said teachers in many schools in the province had been 'trans-languaging' and code-switching for years. 'Teachers used mother tongue to explain concepts. The only limitation was that this was not made official; however it worked. This mother tongue-based bilingual education was there when we learnt Izibalo , Ezingcwele , Ezentlalo and Ezempilo .' He said by using a mother tongue, teachers were able to simplify content. 'It has been published by various scholars that children who learn in their mother tongue understood the content taught better than those who learn the same content in a second language.' However, Makeleni said parental involvement and participation were important in a child's academic performance. '... in some schools, teachers are complaining about lack of parental involvement and participation in their children's academics. 'One wonders if we are not indirectly excluding parents through the language used in teaching and learning. What if parents are also struggling in understanding the concepts in a second language? Mother Tongue-based Bilingual Education addresses that.' Makeleni questioned the capacity of the SA economy to absorb a workforce that learnt through mother tongue education, specifically in indigenous languages.
