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.

Wag-’n-Bietjie dominates for sixth consecutive year

The First-year Athletics event was a celebration of colour and fun. Besides the athletics on and around the track at Pellies Park on the Bloemfontein Campus, the first-years encouraged their different residences with great enthusiasm.

Six out of six.

This is the proud record Wag-’n-Bietjie can boast of after the residence walked away with the women's athletics trophy for the sixth year in a row during the University of the Free State's first-year athletics meeting.

This year's men's winner, Vishuis, attained a hat trick on 20 January 2016 at Pellies Park on the Bloemfontein Campus when the residence was once again named as the athletics champion. Vishuis also won in 2014 and 2015.

What makes Wag-’n-Bietjie's triumph even more remarkable is the fact that the residence ran the fastest, jumped and threw the farthest in eight out of the past nine years. Marjolein won in 2010.

Sonnedou was second, with Roosmaryn and Soetdoring collectively the third women's residences. In the men's division, Legatum and Armentum were second and third respectively.

Sonnedou has the best spirit

The event, a celebration of colour and fun, was characterised by groups of singing first-years yelling their lungs out. The UFS Student Representative Council judges the winners of the different Spirit trophies.

Sonnedou was the overall winner of the Spirit trophy – something even more important than the action on and around the track for some residences.

Sonnedou was named the winner in the division for women's residences, after which the residence was also crowned as overall winner. Welwitschia and Vergeet-My-Nie were second and third respectively in the women's division.

In the men's division, Armentum, who continued singing even when it was raining later in the evening, was the well-deserved winner of the Spirit trophy. Villa Bravado was second with Tswelopele third.

Conlaurês won the Spirit trophy for Co-ed residences, with Imperium and Kagiso second and third respectively.

Wayde a special guest

The Kovsie athlete, Wayde van Niekerk, who also participated in the first-year athletics meeting in his day, was a special guest.

The 400 m athlete, who will represent South Africa at the 2016 Olympics in Rio de Janeiro, was presented to the first-years during the official welcoming ceremony.

Van Niekerk is still the Kovsie record holder in some events, including the 200 m and the 400 m, as well as the 4 x 100 m team relay event.

Team and individual results for the event.
