In celebration of African linguistic diversity and the power of indigenous creative expression, the UFS African Languages Press, in collaboration with the Academy for Multilingualism on the Qwaqwa Campus, kick-started Africa Month with the launch of the African Languages Press on the campus, as well as the Multilingual Hub, and finally, its first product, a book titled Haeso ke Naheng by former UFS Qwaqwa Campus student Matsimela Setenane.

The African Languages Press was launched on the Bloemfontein Campus in May 2022.

In her opening remarks, Dr Tholani Hlongwa, Deputy Director of the Academy of Multilingualism, said the Languages Press and Multilingual Hub would work together to publish high-quality original content in African languages. “We will promote writing in African languages and position the UFS as a hub, promoter, and preserver of African languages in South Africa. We want to support upcoming authors by providing high-quality editorial services and bridge the gap left by the mainstream publishing industry by increasing the publication of African languages, among other things.”

A creative expression of the Sesotho language

Haeso ke Naheng, a fictional Sesotho novel, looks at the life of Thabo, an orphan who witnessed the takeover of his place of birth. He grows up to be a revolutionary Sesotho warrior who fights to reclaim his birthplace. His story resonates with his life; the author told the audience during the book launch. “Through writing this book, I discovered a lot about my origins as a Mosotho man. It is our responsibility as young people to continue digging to discover who we are so that we, too, will have knowledge to pass on to our children”, he said.

Setenane was born and bred in Qwaqwa and obtained his BSc degree majoring in Physics and Chemistry qualification from the Bloemfontein Campus in 2019. His love for Sesotho literature has grown over the years, and he hopes to produce more literature that celebrates the creative expression of his culture. He is currently busy with his first poetry anthology, which is also in Sesotho.

A platform to reignite free expression in indigenous languages

The guest speaker for the launch was Dr Edwin Mohatlane, who praised the UFS for the strides it's taking towards preserving and promoting African indigenous languages. “This is a milestone in the development of our languages. Our languages are doomed to extinction because of our attitudes towards them. I hope that the African Languages Press and the Multilingual Hub will be used to promote the literary and aesthetic talents in our languages”, he said.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
