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.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
