As part of an exchange initiative facilitated by the Erasmus+ Mobility Programme, Jeremiah Hlahla, a student at the University of the Free State (UFS), is nearing the completion of his PhD studies at the University of Debrecen in Hungary. Hlahla’s journey, which began in February 2024 and is set to conclude in July 2024, has been a remarkable learning opportunity. “As a first time-traveller to Europe, I have thoroughly enjoyed engaging with people from different countries and cultures,” he said.
The benefits of international collaboration
Hlahla is currently pursuing a PhD in Botany, focusing on plant stress physiology. “My current PhD project investigates the physiological, biochemical and morphological responses of vegetable-type soybean, or edamame, to combined drought and heat stress,’’ he explained. He considers the University of Debrecen the ideal institution to complete his research due to its extensive expertise and resources in similar projects. He noted that his colleagues at Debrecen conduct significant work on plant protection against biotic and abiotic stresses, including salt and drought stress, as well as proteins and amino acids in barley and other legumes.
Given the vast knowledge available on similar projects, Hlahla has found substantial engagement with his work at the University of Debrecen. “Upon arrival, I delivered an introductory lecture presenting my UFS project on the synergistic effects of combined drought and heat stress on the physiology and biochemistry of edamame. It was an engaging session as everyone could relate to my work and asked many questions,’’ he said.
Insights gained from the exchange
Hlahla has also gained valuable lessons that will assist him in his research career, including biotechnology and physiology tools. “I learned how to prepare samples and use high-performance liquid chromatography (HPLC) and reversed-phase ultra-high-performance liquid chromatography (UHPLC) to quantify proteins and amino acids,’’ he said. These techniques are beneficial not only for his current work but will also support future soybean research.
As his experience at the University of Debrecen nears its end, Hlahla reflects on the collaborations and friendships he has formed, which stand out as a significant highlight.
Photo manipulation in journalism: evil, crutch or lifebuoy?

Since the 1800s the manipulation of photographs has been common practice, and who can forget the OJ Simpson Time magazine cover in 1994? Albe Grobbelaar, lecturer in the Department of Communication Science at the University of the Free State (UFS), asked in a special lecture on 18 August 2017 whether “Photo manipulation in Journalism” was an evil habit, a crutch or a lifebuoy.
“As a journalist I have always been interested in photography. And the principle of photo manipulation or tampering with photos, as we call it, is something that has interested me ever since,” Grobbelaar said. Photo manipulation is an area that has garnered many academic interest and is not a new trend but a practice that started in the 1830s when photos came into popular use. “It is not always done with ulterior motives, artists played with photographs to get unique effects.” Photo manipulation is not only to create fake news, but is sometimes used to convey novelty and create shock to news readers.
Different viewpoints for different circumstances
He talked about the spectrum of viewpoints on photo manipulation. Some conservative journalism schools say photos should never be retouched while other feel it is fine to tamper with pictures. “What I tried to convey in the lecture was that one should consider different circumstances differently,” Grobbelaar said. As a journalist he believes that news photos should never be manipulated.
He mentioned the example of the mugshot of OJ Simpson that the Los Angeles Police Department released to the media. “Newsweek and Time both used the photo on their front pages, but Time deliberately darkened the picture so that OJ, a black man, would appear more sinister,” Grobbelaar said. It is, however, common practice in the fashion industry to retouch images that are used in fashion magazines.
Use own judgment to validate photos
In the age of social media it has become easy to manipulate photos and which has been labelled fake news. “I would advise people to use their own judgment when validating the authenticity of photos,” Grobbelaar said. It is important to verify whether they are from a reliable news outlet.
