Prof Maryke Labuschagne, a successful scientist who is doing great work to enhance food security on the African continent, admires women who have made an impact, often in male-dominated environments.

Maryke Labuschagne, Professor in Plant Breeding at the University of the Free State (UFS), is known to many for her work to enhance food security. 

She holds the National Research Foundation’s South African Research Chairs Initiative (SARChI) Chair on Disease Resistance and Quality in Field Crops, travelling all over Africa to do research on the genetic improvement of staple food crops in communities. Through decades of research and collaboration, she has also contributed to the establishment of a strong network of researchers on the continent.

During an interview in celebration of Women’s Month, Prof Labuschagne talks about her experiences as a young scientist and how she believes young female researchers should be supported and nurtured. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

Besides the scientists she had the opportunity to work with in countries such as Zimbabwe, Zambia, Uganda, Ghana, Ethiopia, Kenya, Lesotho, Eswatini, Tunisia, and Ethiopia, she also met women who are working the fields to produce crops for their families, raising their children, and living in difficult conditions. “These women, who make it work against all odds, inspire me,” says Prof Labuschagne.

Other women she admires and who have made an impact – often in male-dominated environments – include role models from the past, such as former UK prime minister, Margaret Thatcher; physicist Marie Curie, who was far ahead of her time; and American geneticist Barbara McClintock, who won a Nobel Prize in 1983. 

What is your response to current challenges faced by women and available platforms for women development?
 
“When I started working in the Faculty of Natural and Agricultural Sciences at the UFS in 1989, it was a different world. It was a totally (white) male-dominated environment. The number of women scientists could be counted on the fingers of one hand, and they were often not given the same opportunities as their male counterparts,” she recalls.

Prof Labuschagne continues: “With women having so many opportunities today, it is now totally different.”

She believes women will always have a double burden – being responsible for a family and having to compete on an equal footing with male colleagues in the workplace. There are now, however, many platforms and support systems specifically for women, and she encourages women to make use of every available form of assistance they can get.

I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy. – Prof Maryke Labuschagne
 
What advice would you give to the 15-year-old you?

“I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy.”

She is convinced that young women can have a family and a career, even if they believe it is not possible. 
 
What would you say makes women of quality, impact, and care?
 
“I see many women at the UFS making their mark, making an impact in their chosen fields.”

According to Prof Labuschagne, what would have been unthinkable just a few decades ago, such as women serving as deans and in top management positions, is now a reality. 

“I see young female researchers boldly taking on the world, believing in themselves and their abilities, and knowing they will be successful.” She states that each of these women should be supported and nurtured, as they will have a huge influence on the course of the university’s future.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
