Growing up, many of us were raised in Christian homes practising specific morals and values, and anything outside of that was considered immoral or even ‘demonic’. However, what happens when you have a dual identity, and you embrace a bit of both?

On 29 June 2022, the University of the Free State Faculty of Theology presented a Table Talk Webinar with Dr Nomfundo Mlisa, titled ‘African Christianity: interconnections between religion, culture, and identity’. These webinars cover a variety of burning topics that deal with contentious issues across the country. Attendees emerged from various parts of the world, including Nigeria and Germany.

Dr Mlisa is a published author, qualified nurse, traditional healer, as well as preacher of the Word. Her talk was based on personal experiences of being Xhosa and being brought up as a member of the Methodist Church of Southern Africa in a strict Christian environment. She was on her journey to becoming a preacher when she realised that she needed to undergo the spiritual healing training (ukhuthwasa) and was faced with resistance from the church minister/s, forcing her to leave church because ukuthwasa was against the church policies.

Her journey has been challenging, because she only acknowledged her ancestral calling at the age of 42, following a series of occurrences that nearly cost her her children. Dr Mlisa hinted that, besides being against church policy, one of the reasons was that the Xhosa nation considered ukhuthwasa to be witchcraft due to the similarity in the pronunciation of words: ukhuthwasa, meaning undergoing spiritual training; ukuthwala, which is an ancient activity of gaining powers for wealth; and ukhuthakatha, meaning witchcraft.

“Rev Mabusela of the Methodist Church invited me back to the church and I was ordained as a reverend. However, my ordination was held at the East London Correctional Services, and it was then that I realised I was a prisoner of faith and tradition,” she said.

Is there a link between ukuthwasa and Christianity?

Besides the fact that philosophy could not prove the linkage, Dr Mlisa said that the link exists, but Christianity has strongly influenced Africans to integrate Christian values into their cultural value systems, as evidenced by various authors. This led to various people with spiritual calling disowning their cultural identities as well as their being.

“In Christianity, there are faith healers and prophets, whereas culturally, we have traditional healers; however, they have one objective, which is to heal the people. But because people wanted to accommodate their gifts in Christianity, such names were given. Furthermore, Christians recognise angels, while traditionally, ancestors are recognised,” she explained.

Looking into different practices in both the Traditional and Christian religions, they both have elements of training, ‘ukhuthwasa’. This is mainly because they all undergo different types of training under a senior person. A senior faith healer trains a junior, whereas a ‘gobela’ trains a traditional healer.

The society is also coming to accept all religions, with most people now wearing traditional healer beads everywhere, including work. There are also traditional healers who are modern doctors, demonstrating that these innate or hereditary abilities are a common language.

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.

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.
