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.

Prof Heidi Hudson, director of the Centre for Africa Studies at the University of the Free State, was recently appointed by the President of the International Studies Association (ISA) to serve on the Committee on the Status of Women from March 2016 to April 2018. 

Representing over 100 countries, ISA has more than 6 500 members in North America and internationally, and is the most respected and widely-known scholarly association in the field of International Studies. 

She anticipates that her role on the committee will complement her research interests in feminist security theory and practice in Africa. “I am looking forward to playing a part in the advancement of southern scholars, and the promotion of their voice in global academe.”   

Prior to Professor Hudson’s appointment, she served as a member of the executive of the Feminist Theory and Gender Studies (FTGS) Section of ISA.

Representing women of the world in academia

The Committee on the Status of Women has the task of reviewing the status of women in the profession, and making recommendations to the president and the Governing Council of ISA on ways of tracking and increasing the status and visibility of women in the profession.

“Some of the goals of the committee for the 2014 to 2016 period include reaching out to women scholars in the global south; creating an ISA networking website for women scholars; and surveying perceptions of the international relations climate and its needs,” said Prof Hudson. It is also responsible for “tracking gender balance within ISA and its journals, and supporting ISA regions in fulfilling the mission of the Committee on the Status of Women,” she added.

Connecting scholars globally since 1959

The ISA has been the premier organisation for connecting scholars and practitioners in fields of international studies, and promoting research and education. ISA cooperates with 57 international studies organisations in more than 30 countries, is a member of the International Social Science Council, and enjoys non-governmental consultative status at the United Nations.

Prof Hudson’s research interests concentrate on discursive and material gender deficits of liberal peacebuilding in the post colony, amongst other subjects. She is also co-editor of International Feminist Journal of Politics.
