Creating residences and other spaces that adapt to change without it being forced is a process that requires time, patience, and nurturing. Through recent engagements with Jessica Lynn, a transgender activist from the Kinsey Institute in the United States, the Centre for Gender and Africa Studies (CGAS) and the Housing and Residence Affairs (HRA) division at the University of the Free State (UFS) are committing to creating dialogue and engagements that will foster gender-, transgender- and LGBTQI-positive attitudes for residences on and off the UFS campuses. 

Most of the advocacy and educating work envisaged by the CGAS and HRA did not materialise due to the COVID-19 pandemic. “There are issues coming to the forefront amongst the student community in terms of gender identity and gender fluidity on all three UFS campuses. It is visible that these issues exist, but they are not being discussed,” said Dr Nadine Lake of the CGAS. She added that the Centre would like the UFS to continue addressing issues like acceptance, inclusion, and diversity, but to also focus on gender identity and not just on race.  

Inclusive living spaces: The seed has been planted 

“We reached out to Housing and Residence Affairs (HRA) around creating more education and advocacy for students and staff within HRA around transgender identity specifically, but then also gender,” Lake said. According to Vency Mupupa, Senior Officer: Accommodation Services at HRA, the seed for a broad-based gender awareness project within on-campus residences started in 2019, when HRA was tasked with conducting research into inclusive housing. 

“The focus is not only on transgender people but the LGBTQI community at large. We are starting small, but eventually it will affect the larger student population,” Mupupa said. 

She emphasised that the focus is not only on students in residences but also on staff within HRA and the residences. “We have 25 000 students, and on-campus residences can only accommodate around 6 000 students, so it is a drop in the ocean, but if we can educate everyone else the space will move away from being unaccepting and become more inclusive.” 

Transgender awareness breaks down walls 

Referencing her own experiences, Lynn, who is a transgender woman, said that advocating for gender awareness is all about creating safe spaces for people to be their authentic self. “It is a very closeted feeling,” she said. “When I transitioned, I experienced a lot of bad things, and I wanted to use my experience to help educate others so that are not trapped the same way I was. There is a very small percentage of people worldwide who identify as transgender… It is not like there are no transgendered people here, it is just that they are scared of coming out.” 

Universities are the perfect space

Lynn decided her awareness campaigns should focus on university students because the students she reaches are the next generation of doctors, lawyers, politicians, and judges. “It is all about how we can educate the next generation.”

Most university or college students are going to progress in their careers and will be able to use their influence to educate the next generation. “But, most importantly, most of these students are going to become parents – and sooner or later one of them might become a parent to a bisexual, transgender, or gay child, and through my presentations it would have hopefully opened a lot for them to comprehend,” Lynn said. 

Lynn is internationally renowned for her transgender awareness work and advocacy, and her longstanding relationship with CGAS widened the scope to intensify this project. “Jessica’s work is very important, firstly because of her affiliation with the Kinsey Institute, but most importantly her work in transgender identity,” Dr Lake said. Lynn has presented classes, seminars and talks at some of the leading universities around the globe and in South Africa has delivered talks at the UFS and Rhodes University.

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.
