The Department of Geography on the UFS Qwaqwa Campus recently played host to the Society of South African Geographers Conference (SSAG 2023), which gathered more than 100 students over three days.
Fostering academic growth, collaboration, and inspiration among students and researchers in the field of geography, the Department of Geography on the UFS Qwaqwa Campus recently played host to the Society of South African Geographers Conference (SSAG 2023), which gathered more than 100 students over three days.
Following a five-year hiatus, the three-day conference comprised student proposal presentations in different fields: human geography, environment geography, geoinformatics, and physical geography, divided into breakaway sessions over two days. Furthermore, day three of the annual conference included an excursion to the Basotho Cultural Village and Clarens.
The three-day annual student conference focused on different themes presented by two main speakers. The topic of the first keynote speaker, Dr Mahlomola Daemane, General Manager of the SANParks Arid Research Unit, focused on the contemporary conservation, transition, and relevance of science in policy and decision making.
The second keynote speaker was Dr Felicia Akinyemi, a Marie Sklodowska-Curie Research Fellow affiliated with the Institute of Geography at the University of Bern in Switzerland. Her work focuses on the intersection of geoinformatics, global change, and sustainability. Dr Akinyemi focused her talk on the integrative geospatial methods and metrics for sustainable land use. She introduced different techniques and metrics and gave students insight in early-career African research.
Speaking about the success of the conference, Nthebohiseng Sekhele, Geography Lecturer on the Qwaqwa Campus and chair of the organising committee, said, “The local organising committee was also very impressed with the quality of presentations from our postgraduate students in Geography, as well as the robust discussions that happened during the parallel sessions in the two days of the conference. We had a positive response of physical and online participation from many universities across South Africa. We are pleased that we have achieved our goal with this conference, which is to inspire the next generation of geographers.”
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.
