Friday 13 December 2024 marks a crucial moment in South African education law. All stakeholders are awaiting the decision regarding implementation of the contentious sections 4 and 5 of the Basic Education Amendment Bill. After President Cyril Ramaphosa signed the Bill into law, he delayed implementation of the sections on language and admission policies for three months. This was meant to allow for consultation on proposals for resolving the conflicts around the contested sections.

The main issue around the language and admission policies is that the Bela Act allows the provincial heads of departments to have the final say on these policies after the school governing bodies (SGBs) have developed them. Some SGBs see this as their powers being usurped, which contradicts the democratisation of school governance. However, cases in which the powers of SGBs have been abused in ways that led to exclusionary language and admission policies presents the need for oversight of these critical school policies.

Friday 13 December 2024 is the deadline for the resolution.

One cannot avoid thinking about the implications of the different possible outcomes of the decision beyond 13 December. The president could approve the Act without any changes, or clauses 4 and 5 could be returned to the National Assembly for reworking.

If approved

If the Act is to be approved with the two contentious clauses in their current form, there will be a barrage of court cases from opponents of the decision. Over the past few months preceding the signing of the Bela Bill and after it was signed on 13 September 2024, the DA, AfriForum and other lobby groups have promised to take the matter to court. In such a scenario, all parties must prepare themselves for long, vicious and contentious court battles that have enormous implications for the political context defined by the Government of National Unity (GNU).

What will add further fuel to the fire is that at the helm of the department in which the Act is being debated is a DA minister, Minister Siviwe Gwarube. Will she toe the line and follow the law as expected by her office? Or will she follow the direction of her political party, which has been clear about how much it abhors the Act, especially in relation to its current form? She could find herself in the firing line.

If approved in its current form, beyond 13 December 2024, the Act will appease proponents who have been clear about their support for it. Proponents of the Bela Act, such as the ANC (which has been campaigning for it to be embraced by all), SADTU (which on countless matches in support of the Act and have even threatened the president with litigation if they do not get their way), and other political parties like the EFF and the MK Party will be vilified. Considering this, the country’s polarisation is apparent and is a potential and real threat to the GNU/coalition.

If sent back

The DA, AfriForum, and other lobby groups, especially those who want clauses 4 and 5 overhauled, will celebrate, but only for a moment. At least they can battle against the Act’s current form in the National Assembly. Rather than the rigour and expenses surrounding litigation, the different sides must now use their different lawmakers to make a case for them.

The results from the last votes on the BELAB held on 16 May 2024 showed that 223 votes were in favour of and 78 votes against the bill. If these results are anything to go by, there is little change the National Assembly would make to the Act. It will boil down to votes, and the scale will be lopsided. We will be heading for litigation and threats.

At the centre of this is the child whose best interest we are supposed to looking out for. Beyond Friday 13 December 2024, our focus will move away from the child to the National Assembly, the courtrooms, the never-say-no law firms. All eyes will be on the political space.

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.
