Physics excels in Afrikaans Academy for Science and Art symposium
UFS postgraduate students in the Department of Physics attended the Student Symposium of the Afrikaans Academy for Science and Art. From the left are Izak van der Westhuizen (PhD) and Hélène Szegedi (MSc), who both came in second place in their respective sessions. On the right of the banner are Dina Oosthuizen (PhD) and Lucas Erasmus (MSc),who claimed first place in their respective sessions.

Every year postgraduate students from all universities and universities of technology in the country are invited to participate in the student symposium of the Afrikaans Academy for Science and Art.

Honours, master's, and doctoral students from different universities in different scientific fields, including chemistry, physics, computer science, engineering, geography, medicine, etc. participated in the symposium. From the Department of Physics at the University of the Free State (UFS), Dina Oosthuizen (PhD) won a first prize in session 1, Hélène Szegedi (MSc) won second prize in session 2, where Lucas Erasmus (MSc) claimed first place and Izak van der Westhuizen (PhD) took second place in session 3.

'We love what we do'

Students from the UFS do incredibly well each year at this symposium. “These achievements speak of the excellent education and training we receive, especially in the department. Physics students not only have lecturers and supervisors who are well-respected in their own research fields but have access to world-class instruments in our physics laboratories. We also love what we do and see it as a privilege to share our work.

“The symposium is also an opportunity to gain valuable experience in presenting our own research as well as getting exposure to various research topics, methods and scientific disciplines,” said Hélène Szegedi, who is a junior lecturer in the Department of Physics

Symposium unique on many levels



Although every participant has to present in Afrikaans, it is not only Afrikaans-speaking students who participate in the symposium. Szegedi said: “The language requirement for the symposium does, however, create the opportunity to develop Afrikaans further as a science language, and we sometimes have to coin new words or terms to describe our research, making this symposium unique and beneficial on many levels.”

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!
