Study Bug Bites Historian Early
Prof Corene de Wet, South Campus researcher, is a dedicated historian and educator.

From a childhood dream of being a historian, to a decades-long educator and double doctorate-holder, Prof Corene de Wet has led an eventful life. Realising that her undergrad qualification on its own would not get her a job, she completed the Higher Diploma in Education at the then Potchefstroom University for Christian Higher Education. However, “just to buy some time for myself,” she decided to study part-time while teaching in Winburg.

Prof De Wet calls it “being bitten by the part-time study bug.” By 1991, she had obtained her BEd (an honours degree at the time), MEd, and DEd degrees. In 1999, she graduated with a PhD in History. Today, Prof De Wet is still a research associate on our South Campus.

Tremendous milestones and mentors

Dr Lynette Jacobs, co-researcher on several projects, says, “Prof De Wet was the first woman to receive a full professorship in the Faculty of Education, and the first woman in the faculty to obtain an NRF rating. She received her professorship at a time when the academic world belonged to men. She outclassed her peers, rising head and shoulders above the crowd.”

Prof De Wet says her superhero is Prof Daniella Coetzee, South Campus Principal and long-time colleague. “Prof Coetzee is a brilliant academic and organiser. She makes every member of her staff feel special. I am ever thankful that she saw the need for a researcher on the South Campus and that she appointed me in this position,” says Prof De Wet.

“She is a seasoned academic who
still enjoys international recognition.”
—Dr Lynette Jacobs.

Generational history and work ethic

Although much has changed in education since her initial research, Prof De Wet believes that both her doctoral dissertations still bear scrutiny. Regarding the zeitgeist and its impact on the written history of a nation, Prof De Wet says, “We regularly hear many voices today who say that history must be ‘rewritten’. My thesis dealt with exactly that: How different generations of historians wrote histories influenced by the spirit of the time, or by textbooks, or by their own political or world views, or their philosophy on life. Thus, different generations interpret the same events differently.”

During a career spanning more than four decades, Prof De Wet has upheld a strong work ethic. This has enabled her to maintain her C-rating as an NRF researcher. “If one doesn’t dare, if you are too afraid of critique or failure, you won’t get anywhere in academia,” she says, adding, “Criticism is part of academic life. Therefore, take chances, and learn from healthy, constructive criticism.”

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!
