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 has given us 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 which support it.

Powerful voices from public life, intellectuals, public interest and business leaders, academics, naturalists, religious leaders, astrophysicists, economists, and ecologists, and others, will be invited to share and debate their views.

Global Citizen courageous conversation launch
In partnership with the South African Chamber of Commerce based in the United Kingdom, the series launched on 26 May 2021, in a discussion with Prof Petersen on the concept and context of his thinking and how the series will roll out.

If you were unable to join the webinar you can watch the replay on YouTube, or visit the South African Chamber of Commerce website where you'll find recordings of previous webinars.

Join our next Global Citizen conversation on 17 June 2021 with a discussion led by the Chancellor of the University of Free State, Prof Bonang Francis Mohale, a published author and respected business leader who has held chairmanships and directorships at some of South Africa’s top companies, on how we educate for Global Citizenship.

Educating a ‘Global Citizen’ – June 17, 2021 15:00 SAST
We have pleasure in inviting you to the United Kingdom - South African Chamber of Commerce’s next ‘courageous conversation’ with University of Free State Rector and Vice-Chancellor Prof Francis Petersen in his series debating ‘The Global Citizen’.  

Eminent South African business leader and UFS Chancellor, Prof Bonang Mohale, will join Prof Petersen to unwrap the role universities can play in creating a ‘Global Citizen’ mindset to effect material change in a constantly evolving and turbulent international world.  

How do universities produce research, and graduate alumni who go out into the  world, to drive and reflect the bedrock value of Global Citizenship namely that of mutual respect, for others, for all creatures, and the environment which sustains us all?

A university education can be a powerful way to push the ‘reset’ button on the baggage of upbringing and our histories - personal, cultural, national, racial – which shape our world view.  

Universities can promote informed self-reflection, curiosity, and tolerance as a driving force in how we shape our realities, understand our prejudices, promote tolerance, and animate life in a better world.  Prof Petersen and Prof Mohale will reflect on how universities can accelerate and respond with greater agility to this challenge.

Kindly RSVP for the event.

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.
