HUMAN RIGHTS MONTH: Safety is not a privilege, it’s a right

Human Rights UFS news — On 22 March 2023 students gathered on the Bloemfontein Campus for a celebration honouring Human Rights Day.

“As people we have the right to feel safe within the environment in which we live, no matter the circumstances. We cannot walk on the streets being fearful of what might transpire. We have the SAPS which has the constitutional obligation to make sure we feel safe. On campus as students, we also have access to Protection Services, which is tasked with ensuring our safety. It is crucial to understand that we have this section 12 right to safety, because safety is not a privilege, it’s a right,” said Lutho Makhofola during a human rights celebration held on the University of the Free State’s Bloemfontein Campus on 22 March 2023.

Lutho, a fourth year LLB student, is one of many Human Rights ambassadors who are part of the Free State Centre for Human Rights (FSCHR) which hosted the Human Rights Day celebration. The ambassadors led a dialogue with other fellow students under the national theme: ‘Consolidating and Sustaining Human Rights Culture into the Future’. In addition to robust discussions, students also tested their knowledge of the with a quiz before signing a pledge committing themselves to becoming livelong advocates for human rights.

Remembering 1960

Dr Annelie De Man, Coordinator in the Advocacy Division of the FSCHR, said the event was about celebrating the present while reflecting on the past. “The aim is to raise awareness around matters of human rights in celebration of Human Rights Day observed on 21 March.”

Human Rights Day in South Africa commemorates the Sharpeville Massacre which took place on 21 March 1960 where 69 died and 180 were injured when police opened fire on a crowd that had gathered to peacefully protest the pass laws. We now have the opportunity to contemplate on South Africa’s road to democracy, the realisation of change, and the advancement of human rights awareness both in the academic setting and society at large since this significant day in our nation's history unfolded 63 years ago.

Significance for students

According to Limeque Redgard, Student Assistant at the FSCHR and a former Human Rights ambassador, the purpose of the FSCHR Human Rights Day commemorative event was to inform and educate students about their rights, particularly the rights that apply to the university setting, to encourage reflection on those rights and how to exercise them responsibly.

“I believe that such events are important for students because we are in such a diverse space within the university, therefore such events bring us together for a common purpose and allow us to celebrate each other's diversity. Furthermore, the goal is to equip students for the world.”

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.
