Protest
Student protest has been a hot topic on many campuses across the country.

The University of the Free State (UFS) Faculty of the Humanities provided the platform for a robust dialogue on student protests in South Africa. The round-table discussion, titled ‘Humanistic Perspectives on Student Protests in South Africa’, took place on 30 May 2022, with an impressive panel drawn from the Humanities, senior management of the UFS, and student governance.  

Vice-Dean of the Faculty of the Humanities Prof Chitja Twala said the faculty thought it prudent to lead this discussion by hosting a round-table talk. “Student protest will be with us for some time, and we need to engage and talk about these issues from a humanistic point of view – it is important for us,” he said.

“It is only when we dialogue and engage with each other that we can meet each other halfway and understand the problems students are faced with, and students can understand the problems institutions of higher learning are faced with.”  

The dialogue was an opportunity to discuss humanistic perspectives on student protests and included the following topics, among others: dynamics of student protests, the relationship between politics and protests, why protests are a challenge for the higher education sector, and the possible responses to protests by universities. 

“We wanted an academic experience and we wanted to give a sense of the different kind of angles when looking at protest, and we have not even scratched the surface,” said Prof Heidi Hudson, Dean of the Faculty of the Humanities.

Protesting is important in addressing issues

Panellist Prof Sethulego Matebesi, who is an expert on community protests, said protesting is the main modality of expression for social movements in South Africa. He also said that protesting is a key element to celebrate, because people now have the right to protest. 

Student Governance Manager Motlogeloa Moema agreed that protest is important and is not something to be frowned upon. “Protesting is a reaction and a manifestation of grievances that have not been addressed, both in the community and institutions of higher learning,” Moema said. He added that it needs to be acknowledged that protesting is not a bad thing, and that it is “a democratic right enshrined in our Constitution”. 

These sentiments tied in with those of UFS Rector and Vice-Chancellor Prof Francis Petersen, who said that protesting campaigns like the #RhodesMustFall and subsequent #FeesMustFall movements addressed certain issues and were actually helping to resolve and address the issues at hand. “Some of these are not resolved, but the role protest plays is quite critical.” 

Management must ensure stakeholder safety

Prof Petersen aimed to contextualise student protests from the viewpoint of the university management team. He said the UFS is home to both students and staff, and management’s mandate is to ensure that everyone feels welcome and can reach their maximum potential in an enabling environment. “The formal structures must facilitate and ensure that staff and students do what they are here to do,” Prof Petersen said. 

“The question is how that protest is being conducted, as there are rules for protesting; in fact the Constitution tries to assist and guide us on how protest should be conducted,” Prof Petersen said. “Protesting is a constitutional right, and we respect that right at the UFS.”

Student equivalent of dialogue planned

The Division of Student Affairs plans to host a student equivalent of this dialogue in the second semester. “This discussion was to get the perspective from academics, and then we will get the student perspective,” Moema said.

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.
