Besides being the top medical student at UFS in 2021, Dr Mario Vieira is passionate about food, music and sport, and plays the piano and guitar for leisure.

Dr Mario Vieira, one of the University of the Free State’s (UFS) newest graduates in the MBChB programme, says he is fortunate and blessed to graduate from the Faculty of Health Sciences as the top achiever in the class of 2021. Dr Vieira will graduate at the year-end ceremonies. 

Says Dr Vieira: “Privileged is the first word that comes to mind. Yet, there are so many other emotions and feelings involved. One is relieved that the hard work is over for now, but in the same breath, quite sad that this chapter of one’s life has come to an end. Excitement also comes through, knowing that a new challenge lies ahead.” 

Dr Vieira says being the top achiever is undeniably an unbelievable achievement, but there were many other factors and people who made it possible. His family, especially his parents, were his greatest motivation. Their unconditional love and support have made his success possible. 

Multiple factors led to medicine 

According to Dr Vieira, who wanted to be a pilot when he was growing up, there were multiple factors that led to him eventually study medicine. He says: “My first experience with medicine was at a young age when I lost a good friend of mine to cancer. I believe the seed that was planted began to grow when my brother started studying medicine. 
“In high school I made the decision once I realised I was passionate about people and would love to make a difference in the life of others. I think it was the idea that if one could pass this degree, one would be equipped and capable to change lives on a daily basis. My friends in medicine and the support system in Bloemfontein were also incredibly valuable. When times were tough, we would carry each other through,” says Dr Vieira on graduating in one of the university’s toughest fields.

He is starting his internship on 1 January 2022 at Addington Hospital in Durban. 

Besides medicine, this Bothaville, Free State native is also passionate about food, music and sport. He loves cooking and hopes to retire one day with a small restaurant by the sea – cooking food and putting smiles on people’s faces. He also loves playing piano and the guitar.

His message to other students who might be considering studying medicine is: “Be courageous. You are capable of more than you think. Believe in yourself. Hard work, determination and time management can get you where you want to be.” 

Your courage 

Prof Lynette van der Merwe, who took up her new position as Academic Head in the Division Health Sciences Education, Faculty of Health Sciences on 1 December 2021, congratulated the new cohort of UFS doctors and reminded them of the three Cs in the MBChB programme in 2021 – courage, conviction and compassion.

 “I saw your courage, the way you squared your shoulders and looked personal, academic and financial problems in the eye, and endured. You were brave and strong when it mattered most. and stayed true to yourself despite overwhelming odds. You made good choices although they were hard, you found a way to put one foot in front of the other when you were too tired to even think.”

“In the words of the poet Amanda Gorman, “There is always light, if only we’re brave enough to see it. If only we’re brave enough to be it. May you always carry your light into a dark world.”

Mineral named after UFS professor
2017-09-29

Description: Mineral tredoux Tags: International Mineralogical Association, tredouxite, Prof Marian Tredoux, Department of Geology, Barberton 

Tredouxite (white) intergrown with bottinoite (light grey),
a complex hydrous alteration product. The large host
minerals are nickel-rich silicate (grey), maybe willemseite,
and the spinel trevorite (dark grey).


More than five thousand minerals have been certified by the International Mineralogical Association (IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification website, the Mineralogical Magazine and the European Journal of Mineralogy.
