Sharon Pinky Kekana: Deputy Minister in the Presidency for Planning, Monitoring and Evaluation.

The Gender Equality and Anti-Discrimination Office (GEADO) at the University of the Free State (UFS), in collaboration with the Central University of Technology (CUT), recently concluded its fourth bi-annual Gender Practitioners Community of Practice (CoP) conference in Clarens. The event, held from 28 to 30 November 2023, drew participation from gender practitioners representing all 26 Universities across the country. Distinguished guest speaker, Sharon Pinky Kekana, Deputy Minister in the Presidency for Planning, Monitoring and Evaluation, added valuable insights to the discussions.

Tumelo Rasebopye, Chairperson of the Gender Practitioners Community of Practice (CoP), outlined the conference’s key objectives, emphasising the need for thorough and robust engagement on issues raised in previous gatherings and the provision of essential tools for practitioners to implement upon their return to their institutions. Rasebopye stressed, ‘Part of the conference is to ensure that we engage in developing a common understanding and act at a baseline level to address the dynamics in our institutions.’’

The themes explored throughout the Conference

The conference delved into various themes through panel discussions and guest speaker sessions, covering topics such as masculinity, culture, and consent. However, the primary focus was on Gender-Based Violence and Femicide (GBVF), particularly pertinent during the 16 Days of Activism for No Violence against Women and Children.’ Kekana, in her address, considered the conference theme, ‘Accelerating actions to end gender-based violence & femicide: leaving no one behind,’ as a call to action. She urged attendees to continue to raise awareness about the devastating impact of GBVF on women, children and the nation as a whole, citing alarming statistics of 969 women murdered in the first three months of the year. 

Advocate Brenda Madumise, Co-Founder of the Wise Collective, highlighted flaws in the national justice system, pointing to prolonged sexual assault cases and the trauma inflicted on survivors during the waiting period.

Resolutions

Reflecting on the conference, Kekana deemed the discussions as an eye-opener, stressing an integrated approach involving various societal entities, including the church and religious leaders. The gender practitioners pledged to collaborate with groups such as the Student Representative Council (SRC) within their institutions to foster inclusivity.  Rasebopye affirmed, ‘’Our existence is fundamental towards the transformation of higher education, and these conferences will inform the necessary actions towards that course.’’

The GEADO, in partnership with CUT, continues to champion gender equality through informed and actionable discussions. The conference not only raised awareness about GBVF but also galvanized gender practitioners to play an active role in fostering inclusive environments within higher education institutions.

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.
