Takudzwa Nyamunda represented the UFS at the latest Commonwealth Futures Workshop where youth from across the globe convened to develop solutions for social issues.

Gender-based violence, global warming, and inequality are just some of the challenges faced by societies internationally. Examining this and other topics Takudzwa Nyamunda represented the University of the Free State (UFS) at the Commonwealth Futures workshop which convened at the Durban University of Technology (DUT). Participants from 13 nations gathered from 11-14 March 2020 to discuss the future of the world.
 
Over the course of four days, student leaders explored ways of bringing peace and nonviolence to the challenging issues we are facing in the world, under the theme: Reimagining Peace. The workshop was organised by the DUT in collaboration with the Association of Commonwealth Universities (ACU) and the British Council. 

The voice of young people 
International forums such as the Commonwealth Futures workshop are to Nyamunda a prerequisite in these modern times. Nyamunda believes that global problems warrant global solutions. According to the Industrial Psychology Master’s student, young leaders have a crucial role to play in nation-building. 

“My experience proved to me that the differences that come out of our diversity are indeed a source of strength demonstrated by the rich insights that came out of the conference,” said Nyamunda who is also an employee of the UFS Department of Human Resources. 

Producing practical solutions
The three-tiered workshop aimed to bring change to campuses across the world, in communities and beyond. This was the third workshop in the series which has taken place in India and the UK. The outcomes will directly feed into the 2020 Commonwealth Youth Forum to be held in Kigali, Rwanda later this year.

The group of students worked together to develop tangible solutions that address shared global issues such as gender-based violence, climate change and inequality. Joining the young leaders were expert speakers and organisations including the International Centre of Nonviolence, the Gandhi Development Trust, as well as the Commonwealth Countering Violent Extremism (CVE) Unit.

Global solutions for global problems
The Commonwealth states that with more than 60% of the Commonwealth’s 2.4 billion people younger than 30, the voices of young people have never been more important. Students across the globe are setting new agendas for social debates, challenging communities and governments to listen and work with young people to develop solutions to these intersecting issues and bring about real change.

In joining forces with other young thought leaders from around the world, Nyamunda drew on his experience as an International Students Association Founder and first President, the former 2017 Student Representative Council (SRC) member for International Students, and the Vice-Chairperson of the South African Board for People Practices: UFS Chapter. 

As one of the 40 delegates from across the globe, Nyamunda was given a sense of hope after he witnessed how keen young people are to build a better 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.
