Prof Paul Oberholster
Prof Paul Oberholster was one of 29 scholars and scientists that were inaugurated as new ASSAf members in earlier this month (19 October 2022).

Prof Paul Oberholster, Director of the Centre for Environmental Management at the University of the Free State (UFS), is the newest academic from the university to be inaugurated as a member of the Academy of Science of South Africa (ASSAf). 

Prof Oberholster was one of 29 scholars and scientists who were inaugurated as new ASSAf members earlier this month (19 October 2022). At the same time, 10 new members of the South African Young Academy of Science (SAYAS) were inaugurated.

As the official Academy of South Africa, ASSAf honours the country’s most outstanding scholars by electing them to membership of the Academy. ASSAf members are drawn from the full spectrum of disciplines. New members are elected each year by the full membership of the Academy in recognition of scholarly achievement. Members are the core asset of the Academy and give of their time and expertise voluntarily in the service of society. The 29 new ASSAf Members bring the total membership of ASSAf to 659.

Science must be in the service

“I feel very honoured to have been selected as a member of the official national academy of science which represents South Africa in the international community of science academies. I am a strong believer that science must be in the service of society. In all my research, I have shown an interest and determination to bring practitioners, students, and scholars together to pursue and foster the betterment of the human condition through its intimate relation to the natural world. The latter is in strong relationship with the vision and mission of the Academy,” says Prof Oberholster about being included in the academy of science.

This honour comes almost a year after Prof Oberholster won the NSTF-Water Research Commission (WRC) Award for his contribution to water resource management in SA over the past five years, with special reference to the field of biological passive wastewater treatment.

According to him, the ASSAf membership means providing evidence-based scientific advice on water resource issues of public interest to government and other stakeholders. He was nominated by Prof Eugene Cloete, the previous Vice-Rector Research and Innovation at Stellenbosch University for his research focus related to water resource management.

Research has direct impact on the most important resources

Prof Corli Witthuhn, Vice Rector: Research and Internationalisation, says the UFS staff and students are proud of the national recognition that Prof Oberholster received for his lifetime achievements in research on water resource management. His research has direct impact on the managing, protection and rehabilitation of one of the country’s most important resources.  

“The demands on our water supplies will increase in the future as a result of climate change globally. We believe his research will become even more important and relevant in the next decade. We are looking forward to his future achievements and will work with him to provide him with the appropriate UFS support.  Congratulations,” says Prof Witthuhn.

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!
