Opinion article by Prof Sethulego Matebesi, Associate Professor and Academic Head of Department of Sociology, University of the Free State.


There was a time when weekly news coverage of South Africa was dominated by various forms of racism, racial discrimination, xenophobia, and related intolerance incidents that painted a grim picture of respect for human rights

However, in the history of contemporary South Africa there has been plenty of optimism about the prospect of deepening the understanding of human rights in order to entrench a human rights culture among citizens. This optimism is underscored by a range of deliberate actions by the South African government to promote, protect, and monitor the development and observance of human rights through, for example, the South African Human Rights Commission and the Commission for Gender Equality.

Yet, while these institutions – and many other policy instruments to ensure compliance – are central to creating an environment conducive to advancing rights enshrined in the Bill of Rights, citizens also hold significant responsibility to prevent the escalation of discrimination and racial tension. But many of us face an uncomfortable truth we have become accustomed to avoiding: the ability to show unusual restraint in the face of injustice.

The challenge of combating practices that glorify intolerance

Beyond formal political rights, human rights also entail the progressive realisation of the right to the structural social determinants of well-being, such as access to clean water, food, and a healthy environment. However, while the process of social change in South Africa has many unique attributes, the response to the process reflects two extremes.

There are, on the one hand, those who cultivate an image as defenders of the rights of the ‘oppressed’ and are predominantly black activists, and on the other hand, anti-transformation forces who stall the move of the country towards a more inclusive and egalitarian future and are primarily white activists. These activists, whether advancing the reclamation of rights, perpetuate legacies of the past instead of asserting a positive commitment to eradicating socially constructed barriers to equality.

These activists are found everywhere. They are part of our education, religious, political, and social establishments. Reflecting on the painful past of the country, these activists do not help foster diversity as an ethos but advance the conscious and unconscious practices of structural racism. Aided by hyper-personalised social media feeds, these activists can stretch the boundaries of logic and destabilise fragile and established democratic and human rights.

The problem, they claim, is that those who embrace diversity and want to find amicable solutions to longstanding social injustices are either advocates of white supremacy or want to abrogate their right to freedom of expression. In such cases, when people in a hate frenzy find something to hate together, they become bonded. And anything contrary to their beliefs goes into an echo chamber of mockery. 

I do not want to establish a potentially trivialising affinity with branding activists who assert their rights as an attack on human rights. But attention is drawn to instances where noble objectives to confront the tentacles of human rights abuses have been weaponised against what is perceived as ‘the other.’

But how can we navigate this fundamental societal defect? Collective agency to advance the ethos of human rights

After three decades of democracy, attempts to eliminate systematic and institutionalised under-privilege must be welcomed. Likewise, our response to the perceived threats to efforts to enhance diversity as an ethos in public institutions and society matters. In many instances, when subjugated to hatred, hostility, or even violence, there is a tendency to believe that the best approach to such an absurd situation is more absurdity. At its most benign, such a response is not helpful to efforts to embrace diversity. At its weirdest, it garners public sympathy for hate groups and activists.

While there have been concerted efforts internationally and nationally for the progressive realisation of social rights and efforts to strengthen democratic resilience and rights-respecting societies, South Africans have been passing the buck. Rights-respecting citizens have a choice to make. They can continue to pass the buck or help build a culture where everyone achieves their potential and develops into responsible citizens.

I am convinced that beyond formal politics, the attainment of respect for cultural diversity and professing the freedom, equality, and unity of all peoples are contingent upon our collective activism and shared commitments to these values. This collective approach – although some may view it as illusory – is, in fact, our most potent weapon. Reinforcing its commitment strengthens our collective agency and resolve to respect human rights and fundamental freedoms.

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.
