Dr Catherine S. Namakula, Senior Lecturer of Public Law at the UFS and Chairperson of the UN Human Rights Council's Working Group of Experts on People of African Descent.

During the 77th General Assembly of the United Nations (UN), the plight of children of African descent was a main topic of conversation. The conversation was led by Dr Catherine Namakula, Senior Lecturer of Public Law at the University of the Free State (UFS) and Chairperson of the UN Working Group of Experts on People of African Descent (WGEPAD).

On Monday 31 October 2022, in New York, she presented the group’s yearly report, titled ‘Children of African Descent’ to the third committee of the General Assembly. Dr Namakula urged the UN and other stakeholders to avoid using photos of African children and children of African descent in deplorable situations for fundraising and marketing purposes. She stated that "children of African heritage are not synonymous with poverty".

Some of the issues discussed at the meeting included conflicts of law with regard to children of African descent, their disproportionate criminalisation, the intense policing of their families and homes, the racial conditioning of their education, and the use of images of them in degrading circumstances in UN and other stakeholder messaging for marketing and fundraising.

The Working Group recommended the creation of a racial justice index to assess how well states are performing and making progress in improving the well-being of children of African heritage. South Africa was one of the nations that intervened to affirm the report. Among the countries that affirmed other related issues were Russia, Cameroon, China, and Syria.

Dr Namakula also had private meetings with the leaders of the World Council of Churches, UN Women, UNICEF, and other UN agencies to talk about human rights-based approaches to programming aimed at mainstreaming racial justice in their work.

 

African Commission on Human and People’s Rights

In addition, Dr Namakula headed the WGEPAD team to the 73rd regular meeting of the African Commission on Human and People's Rights. She made a statement at the session that brought attention to the opportunities for and necessity of African civil society participation in the work of the Working Group and the UN anti-racism machinery. She made reference to the 'Declaration on People of African Descent' being drafted, to which they may add African perspectives.

Dr Namakula also called attention to the precarious status of victims of modern forms of enslavement, torture, and exploitation in the Middle East and Gulf States, emphasising the important role of civil society in documenting and publicising the tales of vulnerable victims. She emphasised the need for work on the reparations agenda to start right now in order to document Africa's claims and create the necessary institutional and normative frameworks.

She added that efforts are under way to have the UFS Faculty of Law serve as the academic alliance's anchor for the reparations agenda in Africa.

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.
