Pursuing people-powered change: Global Social Innovation Indaba sparks action

Insightful, thought-provoking and inspiring: These were some of the words used to describe the 2024 Global Social Innovation Indaba, which took place at the Centenary Complex on the University of the Free State’s (UFS’s) Bloemfontein Campus from 30 September to 2 October 2024.

The three-day conference was hosted by the global Social Innovation Exchange (SIX) in collaboration with the UFS, under the theme ‘People Powered Change’. The conference brought together leaders and innovators from South Africa and several other countries, including Louise Pulford, CEO of SIX; Markus Lux, Senior Vice-President at Robert Bosch Stiftung, and Desmond D’Sa from the South Durban Community Environment Alliance (SDCEA), among others.

In her opening address, Acting UFS Vice-Chancellor and Principal Prof Anthea Rhoda welcomed the guests and described the conference as an opportunity to “deliberate, debate, and dissect ideas around the all-important topic of harnessing people-powered change in order to build successful societies”.

Powering social change

As part of the conference guests engaged in a series of panel discussions and activities, and attended presentations on various topics.

D’Sa was one of the first speakers, delivering a keynote address titled ‘An activist guide to people-powered change’. He referred to moments throughout his career in which he has actively worked towards change in his community and beyond, and highlighted some of the work the SDCEA continues to do. Guests were also treated to a spoken word performance by Napo Masheane, Artistic Director at the Performing Arts Centre of the Free State (PACOFS).

Advocate Tembeka Ngcukaitobi touched on several points in his talk, such as what the law meant or means to indigenous people. He explored this by referring back to the colonialist era. Ngcukaitobi, who described law as the most ubiquitous and most stable concept that European settlers brought, indicated that it was brought in two faces: the face of justice, and the face of violence. Therefore, he said, “… the future of law that has been most enduring is the ability of the law to transform itself from violence to justice.”

Guests said they regarded the presentations and dialogues as insightful, and also highlighted their appreciation for being able to interact with the campus itself. This sentiment in large part stemmed from the attendees being split into smaller groups and taken to see different parts of the campus. They also got to see an exhibition exploring the role of art in social justice at the Department of Fine Arts.

Lessons from the conference

The last day featured a panel discussion titled ‘Challenging power dynamics and redefining global exchange’, which included an engagement session with the audience. Guests were able to reflect on the information they had acquired at the conference and challenged themselves to continue working towards change and innovation.

“What I learnt from these three days is that since we all want to do the right thing, we all know what the job that needs to be done is,” said Michael Ngigi, CEO of Thinkplace Africa. “As such, we need to be bold in going for that, and really push back on the status quo that is formed by the places we represent.”

Nanotechnology breakthrough at UFS

Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil.

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
