UKZN's youngest PhD graduate 'unlocks secrets of gravity'
Naicker's academic journey has been entirely home-grown, completing her BSc, BSc Honours and MSc degrees at UKZN — all summa cum laude.
UKZN said her doctoral research, conducted under the guidance of Prof Sunil Maharaj and Dr Byron Brassel through the Astrophysics Research Centre (ARC), delved into the intricate theories of Einstein-Gauss-Bonnet gravity, part of Lovelock gravity, a higher-dimensional extension of Einstein's General Relativity.
'Lovelock gravity introduces higher-order curvature terms into the equations of gravity,' said Naicker.
'Studying these helps us understand gravitational interactions in extreme conditions, such as near black holes or in the early universe. My work contributes to uncovering the gravitational dynamics of astrophysical objects in higher dimensions, which could address some of the unresolved questions in cosmology and quantum gravity.'
UKZN said her work produced new exact solutions to complex field equations — earning praise for its potential to shed light on how stars and black holes behave in extreme conditions.
Maharaj, director of the ARC, called her research 'critical in understanding gravitational phenomena' and said it offers 'deep insights into the behaviour of stellar models'.
Brassel, who taught and supervised Naicker over the years, described her as 'an astute student' and said he hopes their collaboration continues.
Naicker is now a postdoctoral fellow at the ARC, supported by the National Research Foundation, and aims to one day become its director. Her work aligns with major scientific projects such as the MeerKAT and Square Kilometre Array telescopes.
'Obtaining a PhD in applied mathematics with a specialisation in relativistic astrophysics is the realisation of a lifelong dream,' said Naicker.
'It stands as testament to years of hard work, resilience and an enduring curiosity about the universe. I hope my journey inspires others — especially young women — to explore the fascinating world of science, technology, engineering and mathematics.'

UKZN in bright idea partnership to find load-shedding solutions
The University of KwaZulu-Natal (UKZN) will become the first South African university powered mainly by renewable energy, with 10,000 solar panels across five campuses, in a pilot project that could help Eskom explore ending load-shedding nationwide. The university has signed a pioneering joint venture agreement with Hong Kong-based tech company Youtility to introduce cutting-edge, AI-driven technology to transform how electricity is managed and distributed, with payments handled through a blockchain billing platform. Eskom Distribution will participate in an observational and advisory capacity, positioning UKZN as a national test bed for 'this next-generation energy technology'. UKZN Eskom Power Engineering Programme acting director Prof Leigh Jarvis said the partnership was more than just an energy upgrade. 'It's a strategic transformation of the university's role in South Africa's energy future. Specifically, it means becoming a national leader in renewable energy: UKZN is on track to be the first predominantly renewable-powered university in South Africa, using solar energy, smart microgrids and real-time AI systems. 'One direct outcome is the creation of a UKZN spin-off company focused entirely on developing and supporting energy-related innovations. This venture will serve as a launch pad for commercialising student and staff ideas that address real-world energy challenges,' he said. Jarvis already has plans to feed advanced research into this ecosystem. He intends to incorporate an internationally patented concept involving liquid air energy storage and superconductor devices. 'Students won't just study energy, they'll help manage it, optimise systems and potentially become founders of new tech companies emerging from this initiative. UKZN becomes a living lab where energy solutions can be tested at scale, with national relevance and international export potential. In essence, this partnership makes UKZN not just a user of energy but an active architect of the future energy economy,' Jarvis said. He said the project could reshape the way electricity is generated, distributed and paid for across the country, offering real solutions to national problems such as load-shedding and grid failures. 'By decentralising energy production through microgrids, this approach reduces dependence on the national grid and minimises outages.' The project can also address electricity theft and nonpayment. 'The blockchain billing system makes tampering with meters nearly impossible and ensures people are billed fairly, discouraging illegal connections. In terms of tariff relief, when everyone pays what they should, the cost is spread fairly, and overall tariffs can remain lower. 'If successful, this model can be applied to schools, hospitals, and even rural villages — making energy access more inclusive and equitable. Why now? South Africa is in the middle of an energy crisis. This initiative is not just visionary — it's urgently practical, aligning with national goals for renewable energy, economic upliftment and digital innovation,' said Jarvis. Speaking at the launch event and signing ceremony held at UKZN's Westville campus, acting deputy vice-chancellor for research and innovation at UKZN, Prof Anil Chuturgoon, called it a 'defining moment' in addressing the country's long-standing energy challenges. 'This concept of green energy is going to transform the energy landscape in South Africa,' he said. Youtility director Wayne Mostert said: 'Wizdom is an evolving, AI-driven utility brain with enhanced capabilities which include real-time, decentralised decision-making and smart discharge of power into micro and macro grids.' Drawing parallels with past tech revolutions, Mostert likened Youtility's ambitions to the digital disruption of entertainment media. 'Where Blockbuster failed to adapt, Netflix scaled using data, agility and customer-centricity. Similarly, Youtility is poised to revolutionise the utility sector through sentient, decentralised, and user-empowered infrastructure, creating a new global standard,' he said.

First sighting of rare spotted ground thrush in Palm Lakes
An exciting discovery of a rare and endangered bird at Palm Lakes Family Estate has brought hope to local conservationists. During a ringing event at the eco-estate on June 1, founders of The LionHeart Experience, Richard and Candice McKibbin – along with other environmentalists – caught and ringed the elusive spotted ground thrush. This follows months of work by the husband-and-wife duo, who, in collaboration with the University of KwaZulu-Natal, officially launched the Citizen Science Census of the ground-dwelling bird, which takes place on July 19 and 20 throughout KZN. The couple is working with ecological academics Professor Colleen Downs, Dr Jonah Gula and Dr Nasiphi Bitani to study and generate new data on the species' population status and distribution. Other North Coast eco-estates, including Palm Lakes, will serve as monitoring sites within the conservation study. The Swiss Ornithological Institute has donated 15 geographic locators to track bird movement. The LionHeart Experience team is thrilled with the breakthrough. They have been studying and protecting Palm Lakes' biodiversity for years but had not previously encountered the bird. 'This has been a passion project for us for many years,' said Richard. 'We've been searching for the spotted ground thrush in the forests of the estate for the past four years. We always believed it was here.' Candice noted that the eco-estate is special for wildlife and continues to yield incredible finds. 'The discovery of the spotted ground thrush is significant and extremely important. We hope to monitor its movements and confirm the presence of additional birds in the estate,' she said. These coastal forest birds breed in the Eastern Cape and Transkei but migrate to KZN during the winter months. BirdLife South Africa and the International Union for Conservation of Nature (IUCN) estimate that only 600 to 1 500 birds remain in the country. The Tinley Manor eco-estate is now considered a potential refuge for the spotted ground thrush. However, some notable threats remain. 'In forests where we have documented spotted ground thrush, we have found numerous cats roaming the area. This is a real threat to the bird's survival, as is loss of natural habitat through development,' said Richard.
