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.

UFS student makes breakthrough in the application of nanorobots
2005-04-21

A student from the University of the Free State (UFS) has made a ground-breaking discovery in the field of microbiology by uncovering a series of new compounds that may in future be used to lubricate man-made nanorobots.

Mr Olihile Sebolai, a full-time student at the UFS’s Department of Microbial- Biochemical and Food Biotechnology, made this discovery while working on his M Sc-study on yeast.

With this discovery Mr Sebolai will also be awarded six prestigious prizes during this week’s autumn graduation ceremony at the UFS.  This university has recognised this exceptional achievement as a build-up to the celebration of national Science and Technology week next month.     

Mr Sebolai’s dissertation on the yeast genus Saccharomycopsis Schionning has been published in an accredited international journal of repute. 

“Words cannot describe how excited I am. I never expected to receive such recognition for my studies.  I am humbled by all of this,” said Mr Sebolai.

The Lipid Biotechnology Group at the UFS recently discovered that some yeasts produce their own water-propelled capsules in which they are transported.  These capsules have different shapes and resemble among others miniature flying saucers, hats with razor sharp brims etc.  “In order to function properly, parts of the capsules are oiled with prehistoric lubricants – lubricants that are produced by yeasts and that probably existed for many millions of years as yeasts developed,” said Mr Sebolai.  

According to Mr Sebolai these capsules are so small that approximately 300 can be fitted into the full-stop at the end of a sentence and are therefore invisible to the naked eye.

“With my studies I discovered many new compounds that resemble these prehistoric lubricants.  These lubricants may in future be used to lubricate man-made nanorobots and are similar in size compared to yeast capsules,” said Mr Sebolai.  The nanorobots are used to perform tasks in places that are invisible to the naked eye and could one day be used, among others, to clean up human arteries.

Mr Sebolai has been interested in the subject of Micro technology since he was at RT Mokgopa High School in Thaba ‘Nchu.  “I was specifically interested in the many possible applications the subject has – in the industry, as well as in medicine,” said Mr Sebolai. 

His next goal is to successfully complete his Ph D-degree.

The prizes that will be awarded to Mr Sebolai this week include:

Best Magister student at the UFS (Senate medal and prize);

Best Magister student in the Faculty of Natural and Agricultural Science and Dean’s medal at the same faculty;

The Andries Brink – Sasol-prize for the best M Sc dissertation in Microbiology;

The JP van der Walt prize for best M Sc dissertation in yeast science;

The Chris Small prize for an outstanding Master’s dissertation; and

Honorary colours awarded by the UFS Student Representative Council
