Dr Grey Magaiza read more — Since joining the UFS in 2008, Dr Grey Magaiza has worked extensively on approaches that can foster the socio-economic transformation of societies.

“The future should be one where communities can decide on their development agenda and futures. That’s the most important for me.” Dr Grey Magaiza, Deputy Director of the Centre for Gender and Africa Studies (CGAS) and Head of the Community Development programme on the Qwaqwa Campus, is passionate about capacitating communities to be agents of change and advancement. His vision for the future emphasises the empowerment of communities to take charge of their development by actively participating in decision making and the implementation of development projects that can improve their lives.

Since joining the UFS in 2008, Dr Magaiza has worked extensively on approaches that can foster the socio-economic transformation of societies. Over the years, he has crafted his research speciality into one that he is most proud of – being an interdisciplinary scientist immersed in the development of communities.

Social entrepreneurship

“I’m in a fortunate position of researching what I like. I say ‘fortunate’, because I’ve taken the time to understand what I’m passionate about, which is the overall field of rural livelihoods and livelihood futures – in short, community development. My research starts from an engaged university, understanding the elements that a university must use to enhance transformation and relevance to its immediate community in terms of development.”

One of the ways he has done this is by looking at social entrepreneurship as a development approach for young people in a rural setting. Through workshops with non-profit and civic organisations in Qwaqwa, Dr Magaiza has been helping these organisations to map out their needs and actively meet them through the involvement and support of external role players.

Community organising

“We understand that communities are part of the national development agenda, but even that national agenda respects community knowledge and intentions and allows communities to shape their identity. A critical enabler of this is community organising. You bring back the capacity in communities to have dialogues on issues affecting them as spaces for engagement, knowledge exchange, and for people to just talk about their way forward.”

By enabling communities to define their development agenda, they can address their specific needs, challenges, and aspirations, he said. “When I look at livelihood futures, it’s quite an exciting aspect of my work – it’s like looking into a fortune tellers’ globe, because you’re not deciding for communities what they should do, but the communities themselves take those decisions.”

Nanotechnology breakthrough at UFS

2010-08-19

Ph.D students, Chantel Swart and Ntsoaki Leeuw

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.
