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.

New electoral body for student elections
2004-07-24

The University of the Free State (UFS) has appointed the Electoral Institute of Southern Africa (EISA) to handle the upcoming election of the Student Representative Council (SRC) and Student Parliament on the main campus.

"EISA specialises in elections and have done vast research on the subject"said Dr Natie Luyt, acting Dean: Student Affairs at the UFS.

Dr Luyt said that the UFS wanted an electoral body that can act as neutral and objective as possible. "EISA is a credible electoral body with the necessary knowledge and expertise. We have full confidence that they will ensure a free and fair election on campus"said Dr Luyt.

"EISA is a neutral party and our main aim is to promote democracy through the process of elections"said Mr Seth Phamuli, Chief Electoral Officer of EISA's UFS election campaign.

Mr Phamuli said that EISA has handled the SRC and Council elections of several other tertiary institutions in the country. These include among others the University of the Witwatersrand , the University of the North, Unitra, Wits Technicon, Vista and Pretoria Technicon. "EISA also acts as the secretariat for the Southern African Developing Countries (SADC) as far as elections are concerned and manages the election processes of various parastatal bodies in the country"said Mr Phamuli.

No changes to the constitution of the SRC have been made for this year's election. "The UFS Council decided last year that any changes to the constitution of the SRC should be submitted for consideration by the Council meeting which took place in June. However, the amendments were submitted late - after the closing date for agenda items to be added"said Dr Luyt.

The elections on the main campus will take place on 11 August 2004 .
