WomensMonth Art exhibition honours courageous South African women
Winnie Madikizela-Mandela became affectionately known as the ‘Mother of the Nation’. She passed away on 2 April 2018. Winnie Madikizela-Mandela by Alf Khumalo on display at the Oliewenhuis Art Gallery.
Art in its many forms has always challenged controversial issues in national and international discourse. The exhibition in commemoration of Women’s Day, titled Speaking out and standing up: An exhibition in honour of South African women, highlights women’s voices by narrating their own life histories. 

In collaboration with the Oliewenhuis Art Museum, the Centre for Gender and Africa Studies (CGAS) at the University of the Free State hosted an art exhibition on 1 August 2018. The exhibition took place on the same day as the national #TotalShutDown protests challenging gender-based violence and rape across South Africa. The exhibition included numerous South African female artists who have combined art and activism and was curated by Yolanda de Kock from Oliewenhuis. The works are on display at Oliewenhuis until 26 August 2018.

The historical representation of South African women

“Tonight’s exhibition focuses on the historical and contemporary representation of SA women, and one woman that deserves acknowledgement, is Winnie Madikizela-Mandela,” said Dr Nadine Lake, Gender Studies Programme Director at CGAS. She also highlighted the fact that “Madikizela-Mandela’s life attests to the multifaceted nature of black women’s lives. Her life reveals that black women are not automatically regarded as agents in their own right, but face discrimination, isolation, and exclusion when they step out of the parameters defined for them.” 

Dr Lake furthermore asserted that, “South African Women’s Month and Day is a reflection and commemoration of women’s achievements but is increasingly being criticised by feminists across the country. While the constitution enshrines the rights of women and prohibits discrimination, it has become clear that there is a huge disconnection between an aspirational ideology and women’s lived realities.” 

Women should lead their own narrative

Sharon Snell, Chief Executive Officer of the National Museum, said, “The dominant voice about Women’s Day is to spoil women and to give them flowers and chocolates on the day, in the same way as for Mother’s Day.” 

Women’s Day has unfortunately been equated to the traditional role that women play. The purpose of Women’s Day is to change those perceptions and to highlight issues of inequality. Snell said, “It is time for women to lead their own narrative.”

The exhibition highlights the important intersection between art and activism and focuses on aspects such as gender-based violence, homosexuality, corrective rape, domesticity and intersectionality, consumerism and feminism, traditional and family histories, women’s and children’s rights, identity and gender, bullying and domestic violence. Snell emphasised the fact that art has not been silenced and has carefully been articulating these important messages around gendered and social inequalities.

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.
