The University of the Free State (UFS) recently had the honour of hosting a thought-provoking guest lecture delivered by His Excellency Dr Reuben E Brigety II, the United States Ambassador to South Africa. Held on 23 April 2024 at the Centenary Complex, on the UFS Bloemfontein campus, the lecture delved into the vital role of higher education in fostering and safeguarding democracies.

Describing the occasion as a pivotal moment for the institution, Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, articulated, "Having the United States Ambassador to South Africa visit our institution and deliver this guest lecture presents an invaluable opportunity. It allows us to gain unique insights into the parallel dynamics and challenges facing our sister democracies, particularly as both our countries approach significant electoral periods.”

Dr Brigety, in his address, underscored the significance of higher education in the context of Freedom Day, celebrated in South Africa on 27 April 2024. He emphasised the role universities play in advancing democratic values, drawing upon the UFS motto, “In truth is the light of wisdom” to elucidate this connection. Highlighting the inspirational figure of the late Charlotte Maxeke, a prominent social and political activist, Dr Brigety noted her pivotal role in both South African and American contexts.

Maxeke, a graduate of Wilberforce University, and her husband Marshall Maxeke, founded the Wilberforce Community College upon returning to South Africa. Dr Brigety underscored the significance of Maxeke’s commitment to civil liberties and education, along with her enduring ties to the Wilberforce University network, in shaping subsequent generations of activists and leaders.

Moreover, Dr Brigety stressed the importance of collaborative efforts between South African and American universities amidst today’s complex global challenges. He advocated for initiatives such as collaborative research projects, joint academic programmes, and student exchanges, citing their role not only in knowledge creation but also in fostering mutual understanding and strengthening bilateral relations.

In concluding his address, Dr Brigety urged the audience to emulate the examples set by individuals like Charlotte Maxeke and Prof Jonathan Jansen, the former Rector and Vice-Chancellor of UFS. He encouraged them to champion the cultivation of the next generation of leaders, thinkers, and change-makers.

“Crystallography forms part of everyday life.” This is according to Prof Elspeth Garman, eminent researcher from the Department of Biochemistry, University of Oxford in England, who was hosted by Dr Alice Brink, Department of Chemistry at the University of the Free State (UFS) Bloemfontein Campus. Prof Garman presented a lecture in the Department of Chemistry, titled ‘104 years of crystallography: What has it taught us and where will it lead’. She also taught the postgraduate students how to refine and mount protein structures in cold cryo conditions at about -173°C.

What is Crystallography?
Crystallography is the scientific technique which allows for the position of atoms to be determined in any matter which is crystalline.
 
“You cannot complete Protein Crystallography without the five key steps, namely obtaining a pure protein, growing the crystal, collecting the data, and finally determining the structure and atomic coordinates,” said Prof Garman. Apart from teaching, she was also here to mentor and have discussions with UFS Prestige Scholars on how to face academic challenges in the professional environment.

Discovery of the first crystal structure of a TB protein

Prof Garman successfully determined the first crystal structure of a Tuberculosis protein (TBNAT), a project that took about 15 years of research. In partnership with the Department of Pharmacology at Oxford University and an outstanding PhD student, Areej Abuhammad, they managed to grow only one TBNAT crystal, one-fiftieth of a millimetre. They also managed to solve the structure and publish it.

Dr Alice Brink, Senior Lecturer in the Department of Chemistry, says, “It’s an incredible privilege to have Prof Garman here and to have her share her wisdom and knowledge so freely with the young academics.”
