Prof Maryke Labuschagne, a successful scientist who is doing great work to enhance food security on the African continent, admires women who have made an impact, often in male-dominated environments.

Maryke Labuschagne, Professor in Plant Breeding at the University of the Free State (UFS), is known to many for her work to enhance food security. 

She holds the National Research Foundation’s South African Research Chairs Initiative (SARChI) Chair on Disease Resistance and Quality in Field Crops, travelling all over Africa to do research on the genetic improvement of staple food crops in communities. Through decades of research and collaboration, she has also contributed to the establishment of a strong network of researchers on the continent.

During an interview in celebration of Women’s Month, Prof Labuschagne talks about her experiences as a young scientist and how she believes young female researchers should be supported and nurtured. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

Besides the scientists she had the opportunity to work with in countries such as Zimbabwe, Zambia, Uganda, Ghana, Ethiopia, Kenya, Lesotho, Eswatini, Tunisia, and Ethiopia, she also met women who are working the fields to produce crops for their families, raising their children, and living in difficult conditions. “These women, who make it work against all odds, inspire me,” says Prof Labuschagne.

Other women she admires and who have made an impact – often in male-dominated environments – include role models from the past, such as former UK prime minister, Margaret Thatcher; physicist Marie Curie, who was far ahead of her time; and American geneticist Barbara McClintock, who won a Nobel Prize in 1983. 

What is your response to current challenges faced by women and available platforms for women development?
 
“When I started working in the Faculty of Natural and Agricultural Sciences at the UFS in 1989, it was a different world. It was a totally (white) male-dominated environment. The number of women scientists could be counted on the fingers of one hand, and they were often not given the same opportunities as their male counterparts,” she recalls.

Prof Labuschagne continues: “With women having so many opportunities today, it is now totally different.”

She believes women will always have a double burden – being responsible for a family and having to compete on an equal footing with male colleagues in the workplace. There are now, however, many platforms and support systems specifically for women, and she encourages women to make use of every available form of assistance they can get.

I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy. – Prof Maryke Labuschagne
 
What advice would you give to the 15-year-old you?

“I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy.”

She is convinced that young women can have a family and a career, even if they believe it is not possible. 
 
What would you say makes women of quality, impact, and care?
 
“I see many women at the UFS making their mark, making an impact in their chosen fields.”

According to Prof Labuschagne, what would have been unthinkable just a few decades ago, such as women serving as deans and in top management positions, is now a reality. 

“I see young female researchers boldly taking on the world, believing in themselves and their abilities, and knowing they will be successful.” She states that each of these women should be supported and nurtured, as they will have a huge influence on the course of the university’s future.

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.
