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.

Open Day 2011 attracts thousands of prospective Kovsies

Low academic standards may be an accepted norm in society, but will by no means be tolerated at our university. This was the core message of the speech made by Prof. Jonathan Jansen, Vice-Chancellor and Rector, to learners, parents and teachers at our university’s annual Open Day, which took place on Monday, 2 May 2011.

Approximately 6 000 people gathered on our Main Campus in Bloemfontein, where they were introduced to senior staff members and deans and allowed to visit each of our seven faculties. Exhibitions from residences and student organisations also competed for the attention of prospective students.

Prof. Jansen assured attendees in the Callie Human Centre that they can look forward to quality education and an academic climate which aims at producing only the best academics and citizens for South Africa. He explained the steps that are being taken to improve the quality of education at the UFS, such as raised entrance criteria and compulsory class attendance in some of our modules.

He said the raised standards have already proven to increase pass rates, as well as attract high-quality students, as we managed to attract 146 students with six or more A-symbols in Grade 12 this year. This is also evidence in the university managing to deliver two Rhodes scholars, Sannah Mokone and Dirk Bester, in one year.

He also assured parents of their children’s safety, reminding them that not only is Bloemfontein one of the safest cities in South Africa, but students at the UFS are also taught to respect each other. “Students are treated as humans and everyone is treated the same. We are all Kovsies here.”

A record number of 1 000 applications for admission to the UFS in 2012 were received and bursaries to the value of R150 000 were given to prospective students during the day.
