Dr Innocent Dande_web read more — Dr Innocent Dande, UFS ISG scholar, has been named the 2021 winner of the JSAS Colin Murray Prize for his research on food politics in Zimbabwe.

Dr Innocent’s Dande’s research on the everyday food struggles experienced by residents of poor suburbs in Harare, Zimbabwe, has earned him a coveted research prize from the London-based Journal of Southern African Studies (JSAS) – the leading international journal in its field.

Start of extended book project

“Winning this award means a great deal for my career plans, especially as I am planning to come up with an extended book project that looks at working classes’ eating habits and foodscapes, or the geographies of food, cooking and eating in lower class suburbs,” says an excited Dr Dande. His aim is to write a sensorial history of how the working classes ate and enjoyed food in Zimbabwean cities between 1980 and 2019.

“One advantage is that this prize provides me with funding to carry out research. If the JSAS is satisfied with the outcome, their tradition is to publish it,” he says.

Not deterred by lockdown

Dr Dande arrived at the UFS at the same time the COVID-19 lockdown was announced, which saw many of his colleagues hastily returning to their home countries. His decision to stay indirectly led to his application.

“I was spending so much of my time in my room at Kovsie Inn during Level one of the lockdown. Applying for this grant was a way of dealing with the boredom that comes with locking oneself in for too long,” he explains.

His application was titled, Cooking, the crisis and cuisines: household economies and food politics in Harare (Zimbabwe), 1997-2020, with much of his research focusing on everyday issues affecting ordinary people, in contrast to “high politics and many other topics that ordinarily shout for more attention.” His aim is to write a social history of the Zimbabwean crisis, focusing on “mundane issues such as the cooking and eating of food.”

Colin Murray Prize background

Colin Murray was a sociologist, anthropologist, and political economist who passed away in October 2013. He taught at various universities in the UK and South Africa and had a special interest in family histories. Carrying a purse of £2 500, the Colin Murray Prize is awarded to an applicant who is within two years of completing his or her PhD, and is meant to assist the winner in engaging in original research in Murray’s fields of interest.

ISG an intellectually enriching environment

The COVID-19 pandemic may have restricted physical interactions with colleagues, but Dr Dande says he still found the International Studies Group (ISG) an intellectually enriching place.

“The ISG continued to hold regular and interesting Zoom seminars. Many of my colleagues have also won very prestigious prizes and are in different stages of completing their various projects. Many others have also published in the same journal (JSAS) and many other high-impact journals.”

He highly values the generous professional advice from his fellow researchers, as well as the input and feedback of ISG Head, Prof Ian Phimister.

“The ISG has shown me that it is possible to dream big and to even contemplate applying for jobs anywhere in the world and not just in Southern Africa,” says Dr Dande.

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.
