You are alone with your thoughts, or at least you think you are. Suddenly, your senses are jolted awake by an unexpected sound. You look around, but see nothing. Then you hear it again: “Ribbit-ribbit… ribbit-ribbit…” You take out your phone – it’s time to discover who your companion is.</p> <p>This is thanks to a new app, Frogs of Southern Africa, the brainchild of Prof Louis du Preez from the Unit for Environmental Sciences and Management at the North-West University (NWU), developed in collaboration with herpetologist Vincent Carruthers.</p> <p>Southern Africa is home to more than 170 species of frogs, a number that reflects its rich biodiversity, but also highlights its ecological fragility. Amphibians, as members of the vertebrate class Amphibia, are the most threatened of all vertebrates globally. This means they also serve as warning alarms for environmental degradation – although those calls often go unheard. Until now.</p> <p>The app’s development is rooted in a desire to change that. “The general public do not know frogs like they know birds and mammals,” says Prof du Preez. “This is an attempt to bring the information to them, to raise awareness and promote appreciation.” Built over several years through painstaking fieldwork, collaboration, and a dash of personal obsession, the app curates a trove of photographs, audio recordings and videos that vividly capture each species’ behaviour, habitat, and most notably, its call.</p> <p>From the croaky “kwaark” of the Common River Frog to the duck-like quack of the Raucous Toad (Sclerophrys capensis), each entry is presented in English, Afrikaans and scientific terminology. More than a mere directory, the app offers geo-referenced tools that allow users to identify which frogs occur where – whether in their back garden or at a planned destination. A photographic key further assists identification, making it invaluable to both researchers and amateurs.</p> <p>That accessibility is precisely the point. The Lite version of the app is free to download. “Our hope is that people will get interested,” says Prof du Preez. In resource-constrained regions where environmental education is often a luxury, mobile apps like this offer a rare intersection of technology and the public good. By making biodiversity tactile and engaging, they foster curiosity and stewardship – especially among the youth, for whom conservation must become second nature.</p> <p>“The app provides, for each of the more than 170 species of frogs of Southern Africa, the Afrikaans name, an explanation of the name, a description of the frog, a description of the call, the preferred habitats, the frog’s habits, and key identification points. Then, for</p> <p>each frog, we provide the call, and for most, we also provide a short video,” Prof du Preez explains.</p> <p>“A very handy feature is that you can ask the app which frog species might occur where you are in Southern Africa, or if you plan to visit a particular area, you can tap on the map and the app will give you a list of which species you may expect. The app also provides a photographic key to help you identify any frog in the region.”</p> <p>Remember that late-night visitor you wanted to identify…?</p> <p>“The goal is to create awareness and get the public interested in frogs. There are no frogs in our region that pose any risks to humans.” It’s not a threat, it’s a potential friend.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Frogs%20of%20Southern%20Africa%202.jpg" title="" /></p> <p> </p> </div> Tue, 01 Jul 2025 11:38:01 +0000 BELINDA BANTHAM 30952 at https://news.nwu.ac.za Decoding hidden signals of brown fat in obesity https://news.nwu.ac.za/decoding-hidden-signals-brown-fat-obesity <span>Decoding hidden signals of brown fat in obesity</span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Phenyo">Phenyo Mokgothu</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Wed, 06/11/2025 - 14:59</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>When brown fat cells start sending the wrong signals, the body’s energy balance can shift in unexpected ways, which is bad news for people living with obesity and type 2 diabetes.</p> <p>Dr Khanyisani Ziqubu, a PhD student from the North-West University (NWU), set out to investigate how brown fat behaves in obesity and whether plant-based compounds might help steer it back on track.</p> <p>Dr Ziqubu recently graduated with a PhD in Biochemistry, with seven publications that came from his PhD. He led the study, which focused on brown adipose tissue (BAT), a special kind of fat. BAT is distinct from the obesogenic white adipose tissue (WAT) – known to store excess energy as fat.</p> <p>BAT burns fat and produces signalling molecules known as batokines, which act like messengers for inter-organ communication and help to keep the body’s metabolic system running smoothly. But in people living with obesity and type 2 diabetes, these signals appear to go off.</p> <p>“I wanted to understand how batokines change during obesity and if natural compounds and flavanoids found in plants, can help regulate their production,” says Dr Ziqubu.</p> <p><strong>Brown fat turns white as obesity progresses</strong></p> <p>Collaborating with scientists from, South African Medical Research Council and the University of KwaZulu Natal, Dr Ziqubu conducted both animal and cell-based experiments. He studied obese and diabetic mice of different ages, tracking body weight, blood sugar and insulin resistance over time. They also looked at the architecture of brown fat in these mice.</p> <p>The results showed that as obesity progressed, brown fat began to resemble white fat, which is mainly for storing energy. This “whitening” of brown fat was linked to increased inflammation and reduced activity of thermogenic genes, which are usually responsible for burning energy.</p> <p>In the laboratory, Dr Ziqubu used a brown fat cell line and exposed it to palmitic acid, a fatty acid common in high-fat diets. The cells began to store large fat droplets, mimicking the same kind of changes seen in WAT from the obese mice.</p> <p>“I observed a progressive loss of the original function of brown fat and becoming more inflammatory with abnormal release of its signalling molecules,” says Dr Ziqubu.</p> <p><strong>Bringing plant flavonoids into the picture</strong></p> <p>Dr Ziqubu also measured the expression of several genes linked to glucose regulation, fat metabolism, nerve growth and inflammation. These included Glut-4, AdipoQ, and VegfA, genes known to play key roles in how the body handles sugar, fat and blood vessels.</p> <p>In a published review by Dr Ziqubu and team, literature suggests that plant-based compounds may help normalise batokine activity and improve metabolism.</p> <p>“There is growing interest in how natural flavonoids might support the regulation of brown fat function,” says Prof Sithandiwe Mazibuko-Mbeje who supervised the study. “Our findings give a possible direction for future research on flavonoid-based therapies.”</p> <p>As obesity and type 2 diabetes continue to rise in South Africa and globally, understanding how tissues like brown fat contribute to disease progression could help identify new therapeutic strategies. The NWU-led team believes their model may be a useful tool in that search.</p> <p>“We’re just beginning to uncover the full role of batokines,” says Dr Ziqubu. “But this work adds to the growing body of evidence that they are key players in metabolic health.”</p> <p>This study was presented in prestigious international conferences, including Biomolecular Horizons 2024 Congress in Australia, 21st International Congress of Endocrinology in the United Arab Emirates, and the Mitochondrial Physiology - from Organelle to Organism Congress in Denmark. For this work, Dr Ziqubu became one of the outstanding PhD candidates globally to be awarded Young Scientific Program 2024 in Australia.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" height="885" id="" src="/sites/news.nwu.ac.za/files/images/Dr%20Khanyisani%20Ziqubu-STORY.jpg" title="" width="512" /></p> <p>Dr Khanyisani Ziqubu and his PhD promoter Prof Prof Sithandiwe Mazibuko-Mbeje.</p> </div> Wed, 11 Jun 2025 12:59:04 +0000 BELINDA BANTHAM 30891 at https://news.nwu.ac.za New species of rain frog, Breviceps batrachophiliorum, discovered https://news.nwu.ac.za/new-species-rain-frog-breviceps-batrachophiliorum-discovered <span>New species of rain frog, Breviceps batrachophiliorum, discovered </span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Bertie">Bertie Jacobs</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Mon, 06/09/2025 - 07:53</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>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.</p> <p>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.</p> <p>“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.”</p> <p>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.</p> <p>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.</p> <p>Prof du Preez and his co-authors, E.C. Netherlands and L.R. 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.</p> <p>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</p> <p>(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.</p> <p>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.</p> <p>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.</p> <p><img alt="frog" class="img-responsive" data-entity-type="" data-entity-uuid="" height="653" id="" src="/sites/news.nwu.ac.za/files/images/Breviceps%20batrachophiliorum%202.png" title="" width="435" /></p> <p>Breviceps batrachophiliorum</p> </div> Mon, 09 Jun 2025 05:53:59 +0000 BELINDA BANTHAM 30880 at https://news.nwu.ac.za Data-driven talent recognised at 2025 BMI Prestige Awards https://news.nwu.ac.za/data-driven-talent-recognised-2025-bmi-prestige-awards <span>Data-driven talent recognised at 2025 BMI Prestige Awards</span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Phenyo">Phenyo Mokgothu</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Thu, 06/05/2025 - 15:11</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Data is the new gold in the digital age and data-driven decision-making is widely used in sectors from banking and finance to the law and telecommunications.</p> <p>The North-West University (NWU) Centre for Business Mathematics and Informatics (CBMI), which is highly regarded across data-driven industries, hosted the 2025 Business Mathematics and Informatics (BMI) Prestige Awards to honour students whose academic performance and industry-focused research stood out across its BMI programme.</p> <p>Held on 9 May at the Kleinbosch venue in Potchefstroom, this year’s awards brought together students, faculty, alumni and industry sponsors to acknowledge achievements in actuarial science, quantitative risk management and business analytics.

Co-edited by Prof Nico Smit from the North-West University (NWU) and Prof Bernd Sures from the University of Duisburg-Essen, the book takes a deep dive into the overlooked role of parasites in aquatic ecosystems.</p> <p>Together Prof Smit and Prof Sures have bridged the gap between how we understand aquatic parasites and their role in our ecosystem. The method followed in this book is what sets it apart, as it investigates parasites as essential components of aquatic habitats rather than disregarding them as merely disease-causing nuisances.</p> <p>The 23 chapters walk readers through the amazing complexity of parasite life cycles, demonstrating how these organisms influence everything from the dynamics of large ecosystems to the health of individual fish. By fusing cutting-edge tools like environmental DNA (eDNA) and stable isotope analysis with traditional ecological information, the book fills a significant gap in the current literature. The most recent findings and developments in aquatic parasitology are presented by 52 internationally recognised writers, including co-editor Prof Sures, five NWU extraordinary professors, four NWU professors and five NWU postdoctoral associates. Their work is presented in three well-organised sections, each focusing on different areas of the field.</p> <p>According to Prof Smit, the book is more than just an academic work. “The book is a valuable resource for those seeking to understand the complex interactions between aquatic parasites and their environments,” he said. “Their implications go far beyond sciences, they touch on medicine, conservation, and how we think about ecosystem health.”</p> <p>The reaction to the book has been remarkable, as it was downloaded over 28 000 times in its first week of release, demonstrating its popularity and global reach. This highlights the standing of the NWU and the University of Duisburg-Essen as pioneers in the field of aquatic parasitology research.</p> <p>Whether you are a student or researcher, or are interested in the hidden workings of aquatic ecosystems, this book provides a novel viewpoint on an intriguing topic. Through funding from the NWU the book is available as an open access resource and you can access and download the book at: <a href="https://link.springer.com/book/10.1007/978-3-031-83903-0">https://link.springer.com/book/10.1007/978-3-031-83903-0</a>.</p> <div class="row"> <div class="col-sm-6"><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Stock%20Image.jpeg" title="" /><p>Prof Bernd Sures (left) and Prof Nico Smit (right) celebrate the publication of their collaborative work on aquatic parasitology.</p> </div> <div class="col-sm-6"><img alt="2" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/The%20Book.jpg" title="" />                 The cover of the book Aquatic Parasitology, which examines the ways in which parasites influence aquatic life. <p> </p> </div> </div> </div> Wed, 04 Jun 2025 10:05:50 +0000 BELINDA BANTHAM 30870 at https://news.nwu.ac.za Groundbreaking study gives frogs and reptiles indigenous names https://news.nwu.ac.za/groundbreaking-study-gives-frogs-and-reptiles-indigenous-names <span>Groundbreaking study gives frogs and reptiles indigenous names</span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Bertie">Bertie Jacobs</a></div> <span><span lang="" about="/user/54" typeof="schema:Person" property="schema:name" datatype="">MOIRA MULLER</span></span> <span>Thu, 05/29/2025 - 12:16</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><ul><li> <h4>Researchers have created a comprehensive list of indigenous names for frogs and reptiles in order to promote inclusive conservation</h4> </li> <li> <h4>People are far more likely to protect what they can name</h4> </li> <li> <h4>South Africa’s indigenous languages have long been marginalised in science</h4> </li> <li> <h4>The inclusion of indigenous names in biodiversity literature is not only good science, but also democratic</h4> </li> </ul><p> </p> <p class="text-align-justify">Frogs, snakes and lizards rarely take centre stage in the worlds of language policy and biodiversity, but then again, South Africa is no ordinary place. A new study published in the <em>African Journal of Herpetology</em> offers a compelling insight into how indigenous knowledge and scientific taxonomy can coexist to make conservation truly inclusive and effective.</p> <p class="text-align-justify">The study, titled <em>Naming South African frogs and reptiles in nine indigenous languages</em>, is a multilingual feat led by Dr Fortunate Phaka of the North-West University (NWU), alongside collaborators from Belgium and across South Africa. It addresses a significant yet overlooked issue in South African science: the near-total absence of frogs and reptiles named in the country's nine official indigenous languages.</p> <p class="text-align-justify">The problem is more than linguistic. Scientific names, which are often in Latin or Greek, are intended to be consistent across the globe, but they are largely incomprehensible to the local communities who live among the species and who are often central to their conservation. This disconnect can be more than a minor inconvenience, it can result in miscommunication, poor policy implementation, and a general lack of public engagement with biodiversity efforts.</p> <p class="text-align-justify">Phaka's research is groundbreaking in both scope and intent. Using online surveys, social media outreach and field interviews, the team compiled a list of over 4 800 indigenous names for all 543 species of frogs and reptiles officially recognised in South Africa, extending the names originally used to group multiple species together. These names span the country’s linguistic diversity and include languages such as isiZulu, Xitsonga, isiNdebele and Tshivenda. Where no specific name for a species existed, the researchers created new names based on familiar descriptive traits, as scientists do with newly discovered organisms.</p> <p class="text-align-justify">Why does this matter? Firstly, it makes conservation more accessible. People are far more likely to protect things they can name, especially if those names are rooted in their own language and cultural understanding. For example, a Xitsonga speaker may not relate to the scientific name Ptychadena anchietae, but the name “Mabhruku”, inspired by the frog’s long legs and springy leap, may inspire a different kind of curiosity and care.</p> <p class="text-align-justify">Moreover, the research reveals that indigenous naming systems often reflect an intuitive ecological logic. For instance, the Xhosa and Zulu words Ixoxo and Isele group frogs based on the texture of their skin. While not strictly scientific, this classification still captures a meaningful distinction. This folk taxonomy often aligns with scientific classifications at higher taxonomic levels (family or genus), though rarely at the species level. The mismatch, or “under-differentiation”, as the authors describe it, is not due to a lack of insight, but rather reflects the observational priorities of communities whose engagement with these animals is shaped by cultural, utilitarian or ecological familiarity.</p> <p class="text-align-justify">The implications stretch beyond taxonomy into social justice and language policy. South Africa’s indigenous languages have long been marginalised in science, a space still dominated by English and, to a lesser extent, Afrikaans. As Phaka argues, including indigenous names in biodiversity literature is not only good science, but also democratic. It enables speakers of these languages to engage with conservation as informed contributors rather than passive recipients. In short, it is a step towards epistemic equity.</p> <p class="text-align-justify">The fact that this project emerged from a collaboration between the North-West University and international institutions such as Hasselt University speaks to the global relevance of local knowledge. While the frogs and reptiles are mostly endemic to South Africa, the model of integrating folk and formal taxonomies and embedding local languages in scientific discourse is exportable. Countries ranging from Brazil to Pakistan have grappled with similar issues, and Phaka’s work could serve as a valuable template.</p> <p class="text-align-justify">There is still work to be done. Why do some species have names, while others don’t? What role do cultural taboos, visibility, and perceived usefulness play in shaping folk taxonomy? These are questions for future research. In the meantime, however, the simple act of naming a frog, lizard or snake in a language that has endured generations is a profound act of cultural and scientific synthesis.</p> <p class="text-align-justify">Ultimately, it turns out that what you call a frog does matter.

He has supervised 25 postgraduate students and nine postdoctoral researchers, and played a crucial role in developing the department that continues to thrive today.</p> <p>According to Prof Thekiso Seretlo, deputy chair of the subject group Mathematics and Applied Mathematics, the timing of the conference was no coincidence. “This was not just about honouring his academic contributions – we also wanted to celebrate his 80th birthday.”</p> <p>Prof Moori came to South Africa in 1983 to help establish the maths department at the then University of Bophuthatswana. “After he retired from the University of KwaZulu-Natal, I spoke to Prof Dan Kgwadi (late vice-chancellor of the NWU) and asked him to bring Prof Moori back to Mahikeng. We held a celebration for his birthday in 2015, and now, even though he resides in England, we felt it was important to recognise his legacy again.”</p> <p>The return to Mahikeng was deeply emotional for Prof Moori. “It is very important for me, especially as this conference is in Mahikeng. I was the first head of department. I built the maths department when late Bophuthatswana President Lucas Mangope was here. I produced a lot of students here – even the late vice-chancellor Prof Dan Kgwadi. It brings back a lot of good memories and I’m really proud that I contributed to algebra in South Africa.”</p> <p>Now living in England with his family, Prof Moori’s influence continues to resonate in academic institutions. The conference served not only as a tribute to his mathematical legacy, but also as a celebration of a life dedicated to knowledge, mentorship and building academic excellence from the ground up.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Attendees-Prof%20Moori-STORY.png" title="" /></p> <p>Attendees of the Mathematics conference in honour of Prof Jamshid Moori.</p> </div> Tue, 27 May 2025 06:04:38 +0000 BELINDA BANTHAM 30844 at https://news.nwu.ac.za NWU and University of Lincoln bring game-based learning to life with Arcademia https://news.nwu.ac.za/nwu-and-university-lincoln-bring-game-based-learning-life-arcademia <span>NWU and University of Lincoln bring game-based learning to life with Arcademia </span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Angeline">Angeline Marokoane</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Mon, 05/26/2025 - 15:27</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>In an exciting move that promises to reshape how we think about education, the North-West University (NWU) has joined hands with the University of Lincoln in the UK to bring Arcademia, a dynamic, game-based learning initiative, to South Africa.</p> <p>This collaboration stems from a formal memorandum of understanding (MoU) signed between the two institutions in November 2023. At the heart of this partnership lies a shared belief: that learning can be innovative, hands-on and even ... fun.</p> <p>Born at the University of Lincoln in 2018 as the Research Arcade, Arcademia began as a simple idea to let students create digital games and share them with others. But it quickly became something more. Today, it is a fully fledged platform where students and staff co-design original games, showcased on custom-built arcade machines across the Lincoln campus.</p> <p>“By 2025, Arcademia has evolved into a vibrant digital ecosystem with multiple arcade cabinets, a desktop launcher and a growing library of student-made games built on platforms ranging from WebGL to native desktop frameworks. It is playful, yes – but it is also powerful. A tool for engagement, creativity, and real-world learning,” says Dr Lance Bunt, senior lecturer in the School of Computer Science and Information Systems at the Vanderbijlpark Campus.</p> <p>Now, the NWU is gearing up to bring Arcademia to life on South African soil. Plans are in motion to install arcade cabinets across all three NWU campuses, creating exciting new spaces where students can learn, interact and experiment across disciplines.</p> <p>Professor Estelle Taylor, director of the School of Computer Science and Information Systems (SCSIS) explains, “Arcademia at the NWU is about more than just games. It is about access, opportunity and using technology to break down barriers. Inspired by the success of a similar initiative in Lincoln, the NWU aims to use these installations to foster local game development, host game jams, and create opportunities for underprivileged young people to engage with digital technologies in a fun and meaningful way.”</p> <p>At its core, this collaboration is a celebration of what happens when education, creativity, and technology come together. Arcademia is not just a project – it is a shared commitment between the NWU and the University of Lincoln to rethink what learning can be.</p> <p>“It also aligns perfectly with the NWU’s broader goals of promoting student mobility, academic exchange and innovation in sustainable, tech-driven education,” says Dr William van Blerk, senior lecturer and subject chair at the School of Computer Science and Information Systems on the Vanderbijlpark Campus.</p> <p>Through Arcademia, the two institutions are quite literally building a bridge – between campuses, countries, and communities. As the NWU prepares to launch its first Arcademia</p> <p>cabinets, excitement is building. Students and staff alike are looking forward to a new kind of learning space – one where curiosity, collaboration and creativity take centre stage.</p> <p>With this partnership, the NWU and the University of Lincoln are not just reimagining education. They are making it more inclusive, more engaging, and a whole lot more interactive.</p> <p>This initiative would not have been possible without the support of the Centre for Teaching and Learning (CTL) and the University Capacity Development Grant (UCDG) funded International Hybrid Teaching Mobility project, which is dedicated  to provide a platform for academics as university teachers to create international teaching partnerships for teaching development. Dr Marieta Jansen van Vuuren, Project Leader for the International Hybrid Teaching Mobility collaborations, explains: “The CTL supports and facilitates internationalisation activities through a professional development strategy with a focus on internationalisation that can create global opportunities to develop a future-ready university teacher who can guide and facilitate learning to prepare future-ready graduates. Collaborations such as Arcademia create an atmosphere of intellectual excitement, through the promotion of scholarly work on teaching and learning to capture and foster reflective practice and innovation that shapes global awareness and intercultural collaboration for both university teachers and students alike.”</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Screenshot%202025-04-16%20at%2014.01.22.png" title="" /></p> </div> Mon, 26 May 2025 13:27:31 +0000 BELINDA BANTHAM 30843 at https://news.nwu.ac.za Uninvited winter guests: why green stinkbugs are taking over your home https://news.nwu.ac.za/uninvited-winter-guests-why-green-stinkbugs-are-taking-over-your-home <span>Uninvited winter guests: why green stinkbugs are taking over your home</span> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Thu, 05/22/2025 - 10:36</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p class="text-align-right">By Gofaone Motsamai</p> <p>The unusual presence of green stinkbugs in offices, homes and public buildings is no cause for concern, according to Professor Johnnie van den Berg from the Unit for Environmental Sciences and Management at North-West University (NWU).</p> <p>“There have been surges in the numbers of many pest and non-pest insects over the last two to three months. This is ascribed to the good rains that were experienced over most of the region,” says Prof van den Berg. He explains that when rainfall is abundant, the host plants of herbivorous insects become more widespread, increasing their chances of survival into adulthood.</p> <p>Stinkbugs, including the Nezara viridula species, commonly known as the southern green stinkbug, feed on a wide variety of plants. This, together with the lush environments found after good rains, boosts their ability to reproduce and survive. While their sudden appearance indoors may be unsettling, Prof van den Berg says they pose no direct or indirect health risks to humans.</p> <p>“It is only when you aggravate them or touch them that they may emit a bad odour, which is aimed at scaring off predators. The incidence of humans showing allergic reactions to such emitted chemicals is believed to be extremely low,” he says.</p> <p>Prof van den Berg adds that although stinkbugs can affect crops such as soybeans and vegetables, their presence in residential or commercial buildings is mostly harmless. As winter temperatures begin to set in, these bugs are expected to disappear naturally.</p> <p>“It is relatively common for certain insects like Nezara viridula to start aggregating during the colder months of the year. Ladybirds are also known to do this. These bugs move to more favourable environments, such as homes, where it is warmer and there is no frost.”</p> <p>No insecticide application is necessary, as these aggregations are temporary and unlikely to lead to reinfestation. “The best thing to do is to sweep them up or off the roof, or out of the corners, and throw them outside,” advises Prof van den Berg</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Johnnie%20van%20den%20Bergh.jpg" title="" /></p> <p>Professor Johnnie van den Berg</p> </div> Thu, 22 May 2025 08:36:02 +0000 BELINDA BANTHAM 30832 at https://news.nwu.ac.za
