Apart from its devastating impact on people’s lives and livelihoods, the COVID-19 pandemic has also affected the nature and quality of our democracies – democracy read in its widest sense here as collective and individual self-determination. Formal, institutional democracy has beencurtailed through the imposition of states of emergency or disaster and the logistical difficulties associated with social distancing. Extra-institutional democratic work, such as protest and social-movement activity, has suffered from prohibitions imposed by law and through state suppression related to ‘lockdown’. The nature (and perhaps democratic quality) of public conversation has changed – for better or worse – from increasing reliance on ‘science’ and ‘scientists’ to justify public choices. The crisis has brought to the fore already existing characteristics of our democracies, such as the prevalence and power of special-interest bargaining, the extreme inequality of our societies, and chauvinist nationalisms that force us to ask whether we have ever had democracy at all. What will be the long-term effects of these impacts of the crisis on our democracies? What will democracy look like post-COVID? What does the crisis teach us about what our democracies have always been?

Join us for a discussion of these and other democracy-related issues in these troubled times by a panel of four hailing from Colombia, India, South Africa, and the USA.

Date: Thursday, 13 August
Time: 14:00-16:00 (South African Standard Time – GMT +2)

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!
