Research possibilities of zebrafish exposed
Leading global genetics laboratories are replacing research on human and animal populations with zebrafish, says Prof Paul Grobler, Head of the UFS Department of Genetics.
The UFS Department of Genetics is on par with current research trends in terms of their zebrafish project. About a year has passed since they seriously started focusing on the potential of this tiny four-centimetre-long fish, and the possibilities are hugely exciting.

Looks are deceiving

Leading global genetics laboratories are replacing research on human and animal populations with zebrafish due to several fascinating reasons, of which the most profound is probably that the zebrafish share large portions of its genome with mammals. For genetics researchers this may make a lot of sense, but most people battle to see any resemblance between a six-foot-tall rugby player or 600 kg buffalo and a small, nearly transparent fish. It is in the detail, the researchers say.

Fast, effective, and visible

“The complete genome sequence of the zebrafish is known, and as much as 84% of genes known to be associated with human disease have zebrafish counterparts,” explains Head of Department, Prof Paul Grobler. Another advantage is the fast breeding rate and short generation time, and the fact that some research is ethically more justifiable when done on fish larvae rather than on adult mammals. The fact that zebrafish embryos are virtually transparent, also allow researchers to examine the development of internal structures without effort. Every blood vessel in a living zebrafish embryo is visible under a low-power microscope.

Multidisciplinary

Zebrafish provide research potential for many different study fields besides that of Prof Grobler and his team, Sue Rica Schneider and Dr Willem Coetzer. In the near future, they aim to have undergraduate students use zebrafish as a research model to develop a real sense of research and laboratory work. The Department of Chemistry are also initiating research on zebrafish housed in the Department of Genetics.

Winning culture helps Kovsies Tennis team claim ninth gold

A winning culture in the Kovsies Tennis Team, combined with good planning, contributed to the University of the Free State (UFS) USSA success recipe.

This is what Janine Erasmus, one of the team's captains, had to say.

According to her, this is why the UFS were able to handle the pressure of being the favourite so well, and this is what helped her team to achieve a ninth consecutive gold medal in Cape Town on 4 December 2015.

This was the sixth year in a row that the UFS triumphed in the combined USSA format since its inception in 2010. In 2007 and 2008, its Women's team won gold, and in 2009, it was the Men's team.

Erasmus was full of praise for the Kovsie coach, Marnus Kleinhans, and Janine de Kock, manager of KovsieTennis.

“We had a build-up of a few months to the USSA tournament, and they (Kleinhans and De Kock) already knew exactly what to do,” she said.

Erasmus, who won a third gold medal, believes her team had great depth this year.

Four in select squad

Kovsies and Maties played in the USSA Tennis Finals for a fourth consecutive year.

Erasmus and her team beat the Stellenbosch team 7 - 3 on 4 December 2015, after they defeated Tukkies 8 - 0 in their semi-final.

Arné Nel, Cornelius Rall, Duke Munro, and Mareli Bojé are the four Kovsies included in the USSA tournament team.

Nel, the other captain from the UFS, won all his matches for the third successive year. Munro won a gold medal at USSA for the seventh year in a row.

Gold for Table Tennis

Three UFS sports teams made it to the USSA finals, all against Maties. The tennis and men's table tennis teams were both winners, but the Sevens rugby team got stuck.

The Kovsie table tennis team beat Maties 3 - 1 in Kimberley.

Silver for Sevens rugby

The Kovsie Sevens rugby team, third at USSA for the past two years, walked away with silver in George on 1 December 2015.

The team was defeated by Maties 10 - 31 in the final. This was after they won 24 - 14 against Pukke in the semi-final, and 28 - 12 against the Central University of Technology in the quarter final.

Tukkies, the 2014 USSA Sevens champions, together with several other teams, did not take part  because the tournament was postponed because of the nationwide student protests.

The Kovsie swimming team took part in the USSA tournament in Johannesburg from 28 November to 30 November 2015.
