Collaborating across continents, the Centre for Gender and Africa Studies at the University of the Free State (UFS), alongside the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), held a pivotal international webinar titled 'Africa’s Global Engagements: Opportunities and Challenges,' on 27 and 28 January 2024.

In the midst of a global landscape marked by rapid changes, Africa finds itself at the epicentre of a new wave of international interest. This intrigue stems from a myriad of factors, ranging from the continent’s abundant natural resources to its strategic geopolitical positioning. However, amidst this renewed attention, questions arise regarding Africa’s agency and its place in the evolving global order.

In recent times, there has been a notable surge in global actors vying for influence in Africa. From former colonial powers to emerging economies like China and India, various stakeholders seek to engage African nations on multiple fronts, spanning from economic cooperation to security collaborations. Against this backdrop, it becomes imperative to delve into Africa’s international engagements to grasp the nuances of its evolving role on the global stage.

Addressing this imperative, the Centre for Gender and Africa Studies at the University of the Free State (UFS), in collaboration with the Centre for African Studies at Jawaharlal Nehru University (JNU) in India and the African Studies Association of India (ASA India), convened an international webinar titled, Africa’s Global Engagements: Opportunities and Challenges. Held on 27 and 28 February 2024, the event was jointly opened by Prof Vasu Reddy, Deputy Vice-Chancellor of Research and Internationalisation at the UFS and Prof Ajay Dubey, former Pro Vice-Chancellor at JNU and currently a professor in the Centre for Africa Studies at JNU. The conference brought together scholars and policymakers from diverse backgrounds and regions, united in their quest to comprehensively understand Africa’s evolving position in the global arena.

In his opening remarks, Prof Vasu Reddy, underscored the timeliness of the conference aligning it to the institution’s visionary framework, Vision 130. He highlighted the centering of Africa as a focal point for addressing broader global challenges emphasising the interconnectedness of Africa’s experiences with broader global narratives. Prof Reddy articulated how Africa serves as a nexus for transnational interactions, intertwining diverse histories, politics, and socio-economic dynamics with the larger global discourse.

Moreover, the conference shed light on the concept of the “Global South” and its implications in the contemporary global order. Participants deliberated on the complexities of African agency within this framework, examining how African states navigate their engagements with a myriad of international actors while asserting their own interests and priorities.

The event not only symbolised a collaboration between the UFS and JNU, as outlined in their Memorandum of Understanding (MoU), but also signified a shared commitment towards prioritising engagements within the Global South. Through platforms like these, institutions like UFS and JNU demonstrate their dedication to fostering meaningful dialogues and scholarly exchanges that transcend geographical borders.

As Africa continues to navigate its place in the fast-changing global landscape, initiatives such as this webinar serve as critical platforms for fostering mutual understanding and cooperation among scholars and policymakers worldwide. By engaging in nuanced discussions and collaborative efforts, stakeholders can collectively contribute to shaping a more inclusive and equitable global order.

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.
