Opinion Article by Dr Ina Gouws, Senior Lecturer: Programme: Governance and Political Transformation, Department of Political Studies and Governance, University of the Free State.
The State of the Nation Address (Sona) of 2023 is upon us. What can South Africans look forward to in this address this year? According to the Presidency, the President will focus on the energy crisis and the rolling blackouts. He will hopefully also shed some light on the disaster legislation government intends to implement to address the energy crisis. Reports that the ANC wants Dr Nkosazana Dlamini-Zuma to oversee the load-shedding state of disaster does not inspire confidence at the onset. What we should take serious note of is what the President will have to say about the plans to move Eskom to the Department of Mineral Resources and Energy; a move widely criticised and frankly, feared. 

No new policies, focus on resolving policy implementation failures

Also, according to the Presidency, the outcomes of the Investing in Africa Mining Indaba taking place from 7 February 2023, will receive attention in the Sona. This event attracts more than 6 000 delegates comprising comprising investors, innovators, companies in the mining and natural resources sector etc. No doubt the President will paint a picture of substantial investments to look forward to which will lead to job creation, development, and growth; a promise made in every Sona of every year of his term without fail, for which there has been very little evidence. 

The Minister in the Presidency, Mondli Gungubele, also told the media that government will not look to introduce new policies but focus on resolving existing policy implementation failures since this is the final year of this government’s term. 

Other than these areas of focus, we can surely expect the usual stats and figures to indicate “progress” or evidence of a caring government; more people receiving social grants instead of no longer needing this assistance, and entirely unrealistic job creation numbers to name two. Collapsing municipalities and ongoing corruption will also probably get mentioned under the umbrella of service delivery with futile promises of eradicating corruption and appointing qualified cadres. This administration’s score card of the past four years justifies cynicism. 

From what I have heard among fellow South Africans and seen on social media, the interest in the Sona is at an all-time low because of the miseries mentioned. We are tired of politicians talking, promising, stating the obvious (a particular skill our President has polished) and blatantly underestimating our collective intelligence. We KNOW there is no concrete plan to address the energy crisis. We SEE incompetent ministers still have jobs. Promises for growth and job creation do not resonate at all because South Africans LIVE THE REALITY of unemployment and poverty. South Africans cannot be blamed when the idea of sitting through an address covering more of the same with no expectation of positive change is something we are not prepared to do.

Indifference towards Sona 2023

Does this indifference towards the Sona this year necessarily mean that the nation has lost interest in politics in general? Many would argue that this is indeed the case. I do not agree. The abject apathy that is taking hold of (especially young) South Africans concerning our country’s formal political processes is an issue widely researched and debated. Apathy is essentially having no feeling or connection to a situation or a complete lack of desire or interest to act or participate. Youth find the formal political processes frustrating, alienating, and less likely to yield desired results, consequently the evident apathy. More and more older South Africans are joining them in these attitudes and therefore have developed feelings of apathy of their own. However, apathy towards the formal political process and politicians (elections and electorates) does not mean that South Africans are not interested in politics in general. To be indifferent is to decide to show no interest and to not care or have any opinion about an issue, situation, or event. It differs from apathy because sufferings, experience and disappointment breeds apathy which is therefore not a decision, but a condition. Indifference towards the Sona 2023 is a decision South Africans make, but their interest, involvement and participation in civic organisations and representative processes remains vibrant. Therein lies our strength and in my opinion, the revitalisation of grassroots influence on South African politics. 

So, if you have better things to do on the evening of the 9 February 2023, go and do them. Spend the time with community members talking about what can be done where you live to help each other and hold your officials accountable. It might also be your group’s turn for a blackout, so spend the precious time with loved ones around a candle or that rechargeable LED light. Do not feel any guilt or that you are missing out. You are not apathetic, merely indifferent. An understandable choice.

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.
