Prof Sethulego Matebesi is a Senior Lecturer and Academic Head of the Department of Sociology at the University of the Free State.

This year’s Freedom Day marks an important milestone in the history of South Africa. It will be 27 years since the first non-racial elections were held in the country, a figure that equals the number of years Nelson Mandela spent in prison.

If equating Mandela with the freedom we enjoy today is not already disingenuous enough, we sunk even lower by assuming that we are close to achieving the civil liberties he embodied. You do not have to go further than read the daily media headlines to understand the extent of the onslaught on the pillars of democracy. That this onslaught comes from political leaders is one of the main reasons why most South Africans are disillusioned with politics, democracy and social issues.

Anarchy wreaking havoc in weak societies

Sociology taught me about the relevance of institutions to a social structure: they control human conduct by setting up predefined behaviour patterns. For example, throughout history anarchy has wreaked havoc in settings where organisations are weak, fragmented, and the citizenry is inactive. Similarly, while peace, unity, and the preservation and the restoration of human dignity are the hallmarks of Freedom Day celebrations, we have become a nation increasingly influenced by symbolic politics and the politics of offence.

It would be hard to find a better example of a significant threat to the pillars of democracy than the widespread onslaught on the judiciary. At the heart of the broader political, legal, and moral issues confronting SA today is how the right of all to equal respect and equal protection under the law has been compromised. Casting doubt about the independence of the judiciary conceals the motivations that most endanger the principles of freedom and equality.

My stance is not aimed at muting the expression of unpopular opinions – a basic tenet of democracy. However, we need to be mindful of events that have and will become powerfully symbolic in altering the nation’s social fabric.

Freedom under attack by populist politics

Any societal change requires some form of flexibility. No doubt, the first decade of democracy was accompanied by hope and the euphoria of the Rainbow Nation. This period demonstrated how different racial groups could live together in harmony, play together, and attend the same school without being required to forsake values they hold dear. This period was punctured by notions of active citizenship and the promotion of democratic cooperation that is based on the acceptance of universal human rights and the rule of law and values of diversity.

While millions of people elsewhere in the world have been forced to flee hunger, war, terrorism, and emboldened autocrats in their countries of birth, the euphoric wave of the Mandela years has, unwittingly and dramatically, worn off during the past decade in South Africa. This turn of events is linked to populist politics that seriously compromise democratic institutions in the country.

In my opinion, there are no heroes in situations like these.

In a country characterised by rampant corruption, violent crime, gender-based violence, human trafficking, racial intolerance, and teenage drug abuse, are politicians the only ones to be blamed for the threats to democracy?

Conquering immorality and safeguarding our freedom

Despite all the challenges we face as a country, we remain a remarkably resilient nation, as is widely acknowledged. This resilience is echoed by how we have navigated our way around a highly divisive and intolerant society to embrace and celebrate our rich and vibrant cultural heritage.

Nevertheless, we have become complacent. We have been vocal against any narrative aimed at restricting our legal, religious, human, civil, economic and political rights. Yet, partly due to our collective inaction, we have failed to use the means to provide a compelling counter-narrative of resistance to the manipulation of state institutions and broader immorality permeating society. This inaction affects the lives and livelihoods of millions of those who do not have the organisational capacity and means to advocate for the causes that affect them.

Let us use this year’s historic Freedom Day celebrations to demonstrate our firm resolve to protect the critical pillars of democracy from further exploitation. This kind of collective responsibility is what South Africa has always been about. Only when our government at all levels, the private sector, and concerned citizens across the country begin a critical partnership and commitment to maintain our democratic institutions and processes that our past losses as a nation become gains and defeats become triumphs.

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.
