Prof Allan Boesak on the role of the church

In a world increasingly defined by the stark contrasts of power and vulnerability, the concept of democracy often reveals itself as a double-edged sword. For the children of struggle – those who have grown up amid the chaos of inequality and conflict – democracy can feel like a distant promise, an ideal often outmanned by the realities they face. The deception of hope lingers in the air as aspirations clash with systemic barriers, leaving many to navigate a landscape where a harsh daily existence obscures the principles of freedom and justice. This exploration seeks to uncover the intricate dynamics between hope and disillusionment, shedding light on the lived experiences of those who yearn for a brighter future yet grapple with the weight of unfulfilled promises.

This was the essence of the public lecture titled Outmanned by Democracy: Children of Struggle, Deception, and Hope, presented by Prof Allan Boesak, a theologian and political activist, on the Bloemfontein Campus.

Prof Boesak confronted the continuous socio-economic challenges faced by South Africa and other nations, including racism, narrow ethnic nationalism, and the revival of tribalism. He emphasised the role of churches in tackling these issues. “The responsibility of churches is to articulate what politicians are often afraid to say,” he stated. “Put your ideologies into practice and leverage your power as ministers of the Word to shape the future and reclaim the dignity of your people. This is where unity transcends colour and stature. Consider the various roles that churches could play in reconciling communities, as seen in the Gaza crisis.”

During his visit to the UFS Faculty of Theology and Religion, Prof Boesak also launched a four-volume set titled The Fire, The River and the Scorched Earth: Fifty Years of Black Theology Through the Lens of Allan Boesak. The first three volumes include his lectures and responses from various theologians, while the fourth contains his sermons. This body of work aims to document, critique, and celebrate the contributions of black theology, highlighting its role in the struggle for justice and liberation and underscoring Prof Boesak’s unwavering commitment to freedom, liberation, and democracy.

In a time when hope and disillusionment coexist, Prof Boesak’s insights remind us of the transformative power of faith and activism in the continuing fight for a more equitable world

Nanotechnology breakthrough at UFS

2010-08-19

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.
