From 24 February 2022 – as an interim solution to the challenges experienced with the disruption of classes on the University of the Free State (UFS) Bloemfontein Campus during the week of 21 February 2022 – the academic programme will continue in a differentiated and flexible online mode in some modules within faculties.

Face-to-face classes will continue in those modules where online teaching is not possible at this stage. Students will be informed by their respective faculties as to which modules will be moving online, and which will remain face to face.

This is a temporary measure to enable the campus to return to stability. The arrangement is estimated to continue for two to three weeks at the most, after which the academic programme will return to the approved teaching plans for 2022.

As an additional measure and to mitigate the challenges of remote off-campus internet access, 10 GB of data is provided free of charge through Global Protect to all registered students for the next month. This will enable students to link to learning resources off campus at no cost. The use of social media is, however, not included in the 10 GB.

Enquiries regarding GlobalProtect can be directed to the ICT Services Call Centre at +27 51 401 9111 (option 4).

Computer laboratories on the campus will remain available to vaccinated students whose modules will be moving online.

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!
