Faculty of Theology and Religion opening
Present at the Faculty of Theology and Religion’s Theology Day were from the left: Dr Eugene Fortein, Dr Siphiwe Dube, Prof Rantoa Letšosa, and Prof Charlene van der Walt.

This year, the Faculty of Theology and Religion at the University of the Free State (UFS) resumed its annual tradition of celebrating the new academic year, after being halted by the COVID-19 pandemic in 2020.

The focus was on a theology of vulnerability for our times, with the theme supported by the text verse from 2 Corinthians 4:7: “We have this treasure in clay jars.” 

God embodies vulnerability

Dean of the faculty, Prof Rantoa Letšosa, left delegates with the inspiring message that one of the treasures in these clay jars is the power of God; power that enables us to stand strong and move forward in trying circumstances, such as the COVID-19 pandemic. He wished all attendees, both in person and online, to experience this extraordinary strength and power of God in the new year. 

Prof Rian Venter from the Department of Historical and Constructive Theology, who led the worship service, talked about humanity that has achieved so much – in the areas of health, space, communication, transport, etc. “Despite all these achievements, we are more insecure, with an intensified sense of vulnerability,” he said. 

“However, the One in whom we believe as our Saviour and Lord is a vulnerable God; he embodied vulnerability. We cannot talk about God as if he is not affected by our vulnerability. He is love. He is affected by us,” he said. 

Depriving people of humanity 

But to be vulnerable can also be seen as to be weak, defenceless, open to harm, in need of care, and deprived of one’s humanity. 

Dr Siphiwe Dube from the University of the Witwatersrand integrated the topic of vulnerability into the paper he delivered, speaking from a decolonialism point of view on the research topic: Towards a Decolonial Political Theology of Vulnerability: Reflections from the Margins. In one of his statements, he said that black people are living in the reality constructed for them and have not discovered what blackness is. He urged the young attendees to make use of spaces created for discussion of this matter. 

Bringing to the table another perspective on this topic, was Prof Charlene van der Walt from the School of Religion, Philosophy and Classics at the University of KwaZulu-Natal. Her paper was on the othering, stigmatisation, and exclusion experienced by the LGBTIQA+ people in the African context in general and the African faith communities in particular. She connected the shame experienced by queer people in a family setting to the story of Joseph in the book of Genesis in the Bible. In her paper: Reflecting on Joseph in the context of Izitabane vulnerability, violence, identity erasure and the imperative of recognition and accompaniment, she stated that Joseph’s otherness informed the vulnerability, exclusion, violence, and identity erasure that happens within the confines of family. 

According to Prof Van der Walt, she wished to not argue for LGBTIQA+/ Izitabane people to be seen or that they somehow ‘pass’ and slip below the radar, but that the recognition called for implied a different kind of seeing: it implied a compassionate witnessing and a humanising recognition. “It implies process, interrogation of power, empathy and imagination, weeping and a commitment to community,” she said. 

Another interesting perspective on the theology of vulnerability was that of Dr Eugene Fortein from the Department of Historical and Constructive Theology at the UFS. In his paper on Vulnerability by Design: On a Theology of Prophetic Solidarity, he asked why the vulnerable is vulnerable? What led to them being vulnerable?
 
“The presence of the vulnerable in South Africa is not an accident. It is not because of fate, but because of a design that is 370 years in the making; deliberately to keep people poor for generations to come.” 

He said it started with Jan van Riebeeck. Legislation such as the Natives Land Act of 1913, the Group Areas Act of 1950, and the Bantu Education Act of 1953 also played a key role. “These were designed to oppress one group and enabling the other to thrive.”

“The scars of this legislation are still haunting us today,” he said. 

The One in whom we believe as our Saviour and Lord is a vulnerable God; he embodied vulnerability. We cannot talk about God as if he is not affected by our vulnerability. He is love. He is affected by us. – Prof Rian Venter

“The vulnerable have names and faces. They are experiencing the effects of being vulnerable on their bodies and that is not to be taken lightly.”

“Do not only pray for the poor and the vulnerable, but work actively to bring restitution,” he said. The church now has the opportunity to be a true servant of Christ,” Dr Fortein added.

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.
