The Department of Geology at the UFS is co-hosting this year’s GeoCongress 2025 with the Geological Society of South Africa. Pictured is Dr Martin Clark, Senior Lecturer in the Department of Geology and convener of the congress.

The Department of Geology in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) and the Geological Society of South Africa will co-host GeoCongress 2025, set to take place from 23 to 27 June 2025 on the UFS Bloemfontein Campus. This prestigious biennial academic event, themed: Embracing change through collaboration, will bring together leading academics, students, and industry experts from across South Africa to explore the latest advancements in geosciences.

The congress reflects the university's commitment to academic excellence, quality, and impact – core tenets of its UFS Vision 130. As a research-led, student-centred, and regionally engaged university, the UFS continues to transform itself to stay relevant within the dynamic and ever-changing international higher education sphere.

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says “The university is proud to co-host this major gathering of established and emerging earth scientists from a variety of disciplines, who will present relevant, timely research topics to a wider audience. The theme underscores the centrality of geosciences to our aspirations as a university for the country and continent, directing us towards a collective sustainable future. We are excited by the ideas to be featured at this conference. More importantly, we are inspired by the prospect of further promoting real interaction and innovation between academia, industry, and society for impactful change.”

A platform for scientific excellence

It is fitting for the UFS to co-host this event, as geologists in the Department of Geology as well as in the province have made significant contributions across multiple fields, including economic geology, palaeontology, and geomorphology.

In the Department of Geology, for instance, researchers are exploring a wide range of topics, including magmatic processes in the platinum-group-bearing Bushveld Igneous Complex, AI-driven prospectivity modelling of global deposits, meteorite impact-related processes in the Vredefort impact structure, and geological and structural studies in the Namaqualand region.

In the Free State, known for its rich mineral resources, including gold, diamonds, and coal, geologists have played a big role in exploring and developing these resources, particularly in the Free State Goldfields, one of South Africa’s leading gold-producing areas. The province also boasts significant coal deposits, important for power generation. In palaeontology, geologists have helped uncover valuable fossil sites, including the Florisbad hominid site, offering insights into the history of life on earth. Additionally, their research in geomorphology, especially around the Florisbad area, has shed light on unique landscapes and depositional environments, including lunette dunes.

In agriculture, geologists have worked closely with farmers to ensure sustainable land use, providing important information on soil composition and erosion prevention. They have also played a key role in the study of groundwater resources, helping to identify and assess borehole sites for irrigation and domestic water supply, which is key to farming in the region. The Institute for Groundwater Studies (IGS) at the UFS is the only institute in South Africa dedicated to geohydrology. Founded in 1974 by Prof FDI Hodgson, the IGS is the oldest institute at the university and has produced more than 1 000 postgraduate students. The institute conducts research on a wide variety of water-related topics. Of special interest is its contribution to the mining and industrial sectors in terms of water management, minimisation of pollution, as well as understanding the nature and behaviour of South Africa's aquifers. The IGS provides a complete service to these industries through field investigations, the development of specialised field equipment, an accredited laboratory, and computer models for aquifer management.

Building on these contributions in the field, GeoCongress 2025 marks an important event on South Africa’s geoscience calendar, showcasing the latest scientific advancements, innovative research, and practical applications shaping the industry. With engaging academic sessions, dynamic workshops, and practical field excursions, the conference offers attendees the opportunity to participate in meaningful discussions, attend insightful presentations, and take part in excursions that bring theory to life.

Opportunities for networking and growth

GeoCongress 2025 is more than just an academic gathering – it is an opportunity for professional growth and networking. Participants will meet peers, mentors, and industry leaders, establishing connections that can lead to new research projects and collaborations.

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.
