Strong athletics team for USSA
The 800m athlete Rynardt van Rensburg is one of several Kovsies who is expected to win a gold medal at the national student champs this weekend.

With three Olympians in their midst and a number of athletes who are serious contenders for a first place, the Kovsie athletics team looks set to make a statement at the 2018 national student champs.

The University Sport South Africa (USSA) event takes place from Friday 27 April to Sunday 29 April 2018 in Sasolburg.

Kovsies finished fifth at last year’s USSA with four gold, four silver and four bronze medals.

There were initial concerns the team might be weakened by the loss of five of their top athletes who are competing at the CAA Southern Region Youth and Junior Championships that is also taking place this weekend in Boksburg.  

Luckily for Tsebo Matsoso (200m), Pakiso Mthembu (5 000m), Tyler Beling (1 500 m) and Lara Orrock (3 000m steeplechase), their events on the USSA programme are only scheduled for Sunday which will allow them to participate in both meetings. Michaéla Wright (SA U20 long jump champion) won’t be able to compete in Sasolburg either. 

Beling and Orrock, along with Ts’epang Sello (800m and 1 500m), Kesa Molotsane (5 000m and 10 000m), Lynique Beneke (long jump), Carien Sander (400m), Hendrik Maartens (200m), Sefako Mokhosoa (triple jump), Mthembi Chauque (20km walk), Peter Makgato (long jump) and Rynardt van Rensburg (800m and 1 500m) are all realistic gold medal contestants.

Van Rensburg, Sello and Beneke have all been to the Olympic Games in 2016. Van Rensburg’s 1:46.15 last month in the 800m currently ranks 21st among the best times in 2018 on the global stage.

Beneke defended her national crown last month with a winning distance of 6.22m and Sello came very close to running her personal best in the 800m at the Commonwealth Games.

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!
