Defender Refiloe Nketsa is one of four Kovsies chosen for the South African U21 netball team.

With no less than four Kovsies in the South African Under 21 netball team, the near future for this sport at the University of the Free State (UFS) is certainly on the bright side.

Chanel Vrey, Refiloe Nketsa, Rolene Streutker, and Boitumelo Mahloko will be in action for the Baby Proteas, as the team is known, in a challenge series. The team will battle the President’s XII (a South African A team) and Uganda from 25 March in Cape Town. 

They all played for the Free State senior side last year. Vrey and Streutker also played for the Baby Proteas against international competition in 2019.

Mahloko – a former Kovsie – and Nketsa have also represented South Africa at junior level in the past. They were team members in the national U16 team in 2017, and a year later Mahloko made the U20 team and Nketsa the SA U18 team.

Khanyisa Chawane will also be in action in the series, playing for the Proteas, while former Kovsie captain Alicia Puren has been chosen for the President’s XII.

Meanwhile, two hockey players, Saré Laubscher and Zimkhitha Weston, have been picked for the South African U21 women’s hockey team. They would have participated in the African qualifying tournament in Ghana at the end of March. This tournament has, however, been postponed to January 2022. 

This is the third consecutive year that Laubscher has made the team. Weston, a former Kovsie, played for South Africa at the 2018 Youth Olympic Games in Argentina.

The African Hockey Qualifier serves as qualification for the Junior World Cup, which is scheduled for December in Potchefstroom. South Africa has already qualified as hosts for the Junior World Cup, but the African crown is up for grabs in Ghana.

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!
