Tharina van der Walt
Tharina van der Walt, a first-year student, won the hammer-throw item at the first Varsity Athletics meeting in Stellenbosch on Friday – the only gold medal for the Kovsies.

Hammer thrower Tharina van der Walt was the bright spark for the University of the Free State (UFS) at the first Varsity Athletics meeting in Stellenbosch on Friday.

Van der Walt, who recently turned 19 and is one of three first-year students in the UFS team of 25 athletes, bagged the only gold medal for the Free State students. She won the hammer throw with a distance of 53,12 m.

The UFS ended in fourth place behind NWU (first), UJ (second), and Tuks (third).

Six athletes achieved second places. Both Sokwakana Mogwasi (100 m) and Ts’epang Sello (800 m) came within a whisker of claiming victory.  Mogwasi lost the 100 m by 00:04 seconds, but in the process improved her personal best from 11,89 to 11,58. Sello (2:08,47) was in the lead for most of the 800 m but was eventually defeated by Niene Muller of Tuks by less than half a second.

Mogwasi was also second in the 200 m with a fast 24,92. Other silver medals were obtained by Yolandi Stander in the discus (52,70 m), Peter Makgato in the long jump (7,66 m), and Marné Mentz in a very fast 1500 m race. Mentz (04:26,63) chopped more than five seconds off her previous best time of 4:32,00. Her time was the third fastest ever in the 1 500 m at Varsity Athletics.

There were three third places: Sefako Mokhosoa (15,47 – triple jump), Petrus Jacobs (14,55 – 110 m hurdles), and the women’s 4x100 m relay team (Mogwasi, Elsabé du Plessis, Joviale Mbisha, and Micháela Wright).

Four athletes just missed out on podium positions, achieving fourth places.

The second Varsity athletics meeting will take place in Potchefstroom on 15 March 2019.

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!
