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.

Conference on religion and reconciliation
2011-07-25

 

At the conference were, from the left, front: Dr Frank Chikane, President of AFM International; Dr Mathole Motshekga, Chief Whip of the ANC; at the back: Rev. Maniraj Sukdaven, Head of our Department of Religion Studies; and Dr Alan Boesak, connected to our International Institute for Studies in Race, Reconciliation and Social Justice, as well as a minister in the United Reformed Church.

In recent times, reconciliation has mainly been politically driven, Dr Alan Boesak stated during a conference on religion and reconciliation. He was one of a number of prominent academic leaders from various religions who participated in the conference: Exploring religious understanding for reconciliation.The conference was presented by our Faculty of Theology and the International Institute for Studies in Race, Reconciliation and Social Justice at our university this week.

According to Dr Boesak, a theologian connected to our International Institute for Studies in Race, Reconciliation and Social Justice, reconciliation means much more than simply former enemies no longer attacking or killing one another; they also have co-exist with a positive attitude towards one another.
 
Speakers from, amongst others, the Christian, Jewish, Baha’i, Rastafarian, Islam and Buddhist religious communities shared their views on reconciliation with one another.Most of these speakers referred to the special value of humankind in each religion. A person’s life has a supernatural dimension, which ought to play a major role in the way in which people treat one another.
 
Dr Frank Chikane, President of AFM International, as well as a speaker at the event, stated that the religious community should and had to be more active in discussions about reconciliation.“If religious leaders do not talk about current issues, all kinds of voices with distorted perspectives will be heard instead,” Dr Chikane added.
 
Reconciliation can only truly take place if the contribution of each group in society is taken seriously. Apart from the high premium placed on rights in society, duties that have to be fulfilled should also be emphasised. Bishop Malusi Mpumlwana from the Ethiopian Episcopal Church is of the opinion that this sense of duty should be established in people’s frame of mind. Adv. Antony Osler pointed out from a Buddhist perspective how important it was to deal with reconciliation by living up to its principles.
 
Rev. Maniraj Sukdaven, Head of our Department of Religion Studies, is very satisfied with the high quality of the contributions during the conference.
