Human Rights Month Graphic
Empowering the youth to shape tomorrow’s democracy.

As South Africa prepares for its national elections scheduled for 29 May 2024, the University of the Free State (UFS) emphasises the importance of youth engagement in the democratic process. These sentiments were echoed during the Human Rights Day event recently hosted by the Free State Centre for Human Rights.

Exercising the right to vote

Aligned with the university’s Vision 130 strategy, which prioritises societal development, the UFS aims to educate and engage its community members on the significance of voting as a catalyst for positive change. Through initiatives like the Human Rights Day event, the university fosters awareness and advocacy for democratic principles, empowering individuals to exercise their right to vote and contribute to shaping the nation’s future.

Advocating for democratic principles

Dr Annelie De Man, Coordinator of the Advocacy Division at the Free State Centre for Human Rights, highlighted the relevance of the Human Rights Day event in light of the elections. “We celebrated Human Rights Day by raising awareness amongst our students regarding the rights that they possess including the right to vote, especially with the South African national elections approaching. We also wanted to convey the message that even though we as a country are experiencing many challenges, we still have our constitutionally guaranteed and hard fought-for rights that guarantee that our human dignity and right to equality must be respected.”

The event held on the Bloemfontein Campus served as a platform to raise awareness among students about their rights and the role of the Free State Centre for Human Rights. Limeque Redgard, a student assistant at the centre, described the event as an opportunity to educate students on human rights within the institution and to introduce them to available support mechanisms in case of rights violations.

Student-led advocacy

Badumetsie Tsieane, Executive Committee Chairperson of the Human Rights Ambassadors, noted the importance of making human rights discussions engaging for students and highlighted the role of ambassadors in promoting awareness and advocacy.

The event showcased the enthusiasm and commitment of students towards understanding and championing human rights, and also underscored the impact of initiatives like the Free State Centre for Human Rights in empowering the youth to participate actively in shaping a just and equitable society.

A call to action

As the nation gears up for the elections, UFS encourages students to exercise their democratic right to vote. Recognising the challenges faced by the country, the university reaffirms its commitment to promoting civic engagement and upholding the principles of human rights and democracy. With the support of initiatives like the Human Rights Day event, the UFS aims to equip students with the knowledge and awareness necessary to become informed and responsible citizens. By fostering a culture of engagement and advocacy, the university strives to contribute to the development of a vibrant and inclusive democracy in South Africa.

As the countdown to the elections continues, the UFS remains dedicated to empowering the youth to play an active role in shaping the future of the nation through their participation in the democratic process.

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.
