Prof Marian Tredoux is a geochemist and lecturer in the Department of Geology at the University of the Free State (UFS). Her research interests are rocks, particularly the chemistry of rocks and the minerals they are composed of – chemicals similar to those found in laboratories, although they occur in nature.
Prof Tredoux started her research career at the University of the Witwatersrand (Wits), after which she spent a number of years at the University of Cape Town (UCT). For the past 11 years, she has been at the UFS, which has brought her in close proximity of her primary field-research area in Barberton. This fascinating part of the country has been the focus of her research for 30 years. She has always been intrigued by the earth's crust in this area, which she describes as "very old, very strange, and very interesting".
Prof Tredoux has been collaborating with colleagues and peers overseas in an attempt to unravel the intricacies of this unusual geological area. Some of these colleagues recently discovered a new mineral in one of the rock formations of the Barberton mountain range. They decided to name the mineral after Prof Tredoux, dubbing it tredouxite. "I am very honoured by this, and very grateful that all these years of collaboration are being acknowledged," Prof Tredoux said.
Cochlear implant changes Magteld's world

Magteld Smith gave her first steps towards the world of the hearing when her cochlear implant was switched on in the Universitas Hospital this week.
A whole team was there to share her joy and disbelief and amazement the moment she could hear noises, voices and conversations. Among them were the Rector and Vice-Chancellor of the University of the Free State (UFS), Prof. Jonathan Jansen, and the acting dean of the Faculty of Heath Sciences at the UFS, Prof. Gert van Zyl.
“I can hear my own voice! I haven’t heard it for a long time. My wish is that every deaf child can get something like this,” she said while prodding Prof. Jansen to speak so that she can hear his voice.
Magteld is working at the university's Centre for Health Systems Research and Development and was deaf since birth. She lost her last bit of hearing due to meningitis last year. Her hearing aids could then not assist her to communicate and a cochlear implant was the only option.
A donation by the Austrian company MedEl made the implant possible. Prof. André Claassen, Head of the Department of Otorhinolaryngology at the UFS, says MedEl was also instrumental in the establishment of the implant programme at the Universitas Hospital and sponsored the first five implants at a total cost of R1 million.
Prof. Claassen says 27 implants have already been done here, but it came to an abrupt halt due to a lack of funds. Strong hearing aids are expensive and cochlear implants are even more expensive at R200 000 each. People with hearing disabilities must be identified at an early age as the brain’s ability to learn sound and voice diminishes after the age of three.
