Prof Francis Petersen, Rector and Vice-Chancellor of the University of Free State, South Africa, invites us to rethink our relationship with the world in a series of ‘Courageous Conversations’ on the theme of ‘The Global Citizen’. Prof Petersen argues that COVID-19 has been a powerful ‘disruptor’ – it was a stark reminder of the need to rethink our identity, of where we belong, our ‘normative’ view of citizenship – if we want to secure long-term survival of our civilisation and the environments that support it.

Global Citizen and the role of Digital Futures – Monday, 27 September - 13:30 SAST / 12:30 BST 

How we turn information into intelligence is the subject of SACC’s next ‘Courageous Conversation’ with University of the Free State Vice-Chancellor, Prof Francis Petersen, in his series debating ‘The Global Citizen’.  “I believe the world needs multi-disciplinary solutions to its global problems.  For this reason, I established the Interdisciplinary Centre for Digital Futures at the University of the Free State as part of my vision to infuse the natural and social sciences and the humanities with everything that digital brings to a multi-disciplinary approach in order to solve real-world problems through the power of big-data analysis,” says Prof Petersen.

Prof Philippe Burger, the UFS Pro-Vice-Chancellor for Poverty, Inequality, and Economic Development, together with Prof Katinka de Wet and Herkulaas Combrink, the interim co-directors of the Interdisciplinary Centre for Digital Futures, will join Prof Petersen to discuss the value that such an approach can bring to finding solutions to real-world problems. They will also share information on some of the exciting projects of international relevance that they are working on. Agriculture and food security, medicine, and attitudes to issues such as, for example, vaccination, education, governance, and ethics are key foci of the centre.

Join us to find out how big-data analysis and a multi-disciplinary approach can transform understanding and deliver solutions to some of the challenges we face as citizens of the world.

The Global Citizen Courageous Conversations series

In partnership with the South African Chamber of Commerce based in the United Kingdom, the Global Citizen Courageous Conversations series that was launched on 26 May 2021, brings together powerful voices from public life, intellectuals, public interest and business leaders, academics, naturalists, religious leaders, astrophysicists, economists, ecologists, and others.

If you missed our previous Global Citizen Courageous Conversations, you can watch the replay on YouTube, or visit the South African Chamber of Commerce website for the recordings.

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.
