A Virtual celebration of Africa Month
On 25 May 2020, Africa will celebrate the 57th anniversary of the founding of the Organisation of African Unity. A central tenet of the organisation, which was the predecessor of the African Union, is African solidarity. Member states undertook to coordinate and intensify their cooperation and efforts to achieve a better life for the people of Africa. The University of the Free State (UFS) has a long tradition of commemorating Africa Day and the ideas underpinning it. Every year, diverse events aimed at advancing African unity and solidarity take place during Africa Month – traditionally, the highlight is the Africa Day Memorial Lecture hosted by the University's Centre for Gender and Africa Studies.
This year, celebrating African unity through significant events involving the physical presence of a large number of people, will likely be impossible. COVID-19 is ravaging the world and Africa may become one of the world regions worst affected by the consequences of the virus. Social distancing may be difficult to achieve in a continent with densely populated urban centres that often feature large informal settlements. Besides, the economies of African nations are not as robust as those of other world regions. The challenge that Africa is facing, appears to be one that can only be mastered by its people acting in solidarity and unity. The continent has already developed an Africa Joint Continental Strategy for COVID-19 Outbreak to combat the virus, and an Africa Taskforce for Coronavirus has been established. The ideas of African togetherness and the underpinning philosophy of Ubuntu may be critical for strengthening African solidarity at a time when it may be more relevant than ever.
The commemoration of Africa Day takes a different theme each year. This year, the UFS 2020 Africa Month celebrations will take a virtual format, with the theme of ‘Africa together forever’ underpinned by the COVID-19 global pandemic. The theme is particularly significant considering the context of the African continent; and only through the demonstration of solidarity and unity can Africa overcome the challenges of the global pandemic.
The University will host a variety of cultural and intellectual contributions on the dedicated UFS virtual Africa Month website. On Africa Day (25 May 2020), a virtual Africa Day function, which will be posted on the website, will conclude the Africa Month commemorations.
The diverse contributions to the 2020 virtual Africa Month activities will highlight the University’s commitment towards creating a diverse, challenging intellectual environment. The UFS strives as a research-led university, to provide an environment in which new ideas are incubated and debated; contributing towards its transformation process and African unity.
Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.
Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.
The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.
It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.
The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.
Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”
“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.
The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.
“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.
And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
