The University of the Free State (UFS) is co-hosting the Global Social Innovation Indaba together with Social Innovation Exchange (SIX) on its Bloemfontein Campus from 30 September to 2 October 2024. This event brings together people from different sectors all over the world to discuss how to accelerate and support people-powered
change and create a better society for generations to come.
The UFS is excited to collaborate with SIX, as its vision and values overlap. During this three-day indaba, aspects such as – what it takes to build accountable, inclusive, and participatory institutions, specifically the future role of universities in South Africa – will be discussed. Themes to be explored include young people as drivers of change, post-industrial transitions and community resilience, the role of art, social change and bridging divides, and systemic approaches to dealing with unemployment.
Some of the speakers and participants in the programme include Carla Duprat from ICE (Brazil); Cheryl Jacob from ESquared Investments (South Africa); François Bonnici from the Schwab Foundation for Social Entrepreneurship (Switzerland); Sir Geoff Mulgan from the University College London (UCL) in the United Kingdom; and Dr Narissa Ramdhani from the Ifa Lethu Foundation (South Africa).
The UFS will also use the opportunity to showcase its campus and offerings to attendees, focusing on its transformation story and some of the interdisciplinary forward-thinking programmes. Guests will also be treated to true South African hospitality, laying the foundation for strong relationships and collaboration.
SIX believes in the transformative power of people working together. Exchanges based on mutual value and reciprocity are the missing link in tackling the world’s problems. As a friendly, expert entry point to global social innovation, their work connects organisations, sectors, communities, and nations to build capabilities and create opportunities for collaboration.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
