East College - Eco Vehicles Team
Overall winners of the 2022 Eco-vehicle race, East College, hard at work to get their car ready for the race held at the Odeion parking lot on the Bloemfontein Campus.

For the first time, the University of the Free State’s 2022 Eco-vehicle race – held on the Bloemfontein Campus on 14 May 2022 – had students from all three campuses participating in the programme and race; a cup was awarded to the college with the best support.

Although the annual event did take place in 2021, only team members were allowed access to campus due to the COVID-19 pandemic and lockdown regulations, and therefore the race was streamed live. 

Karen Scheepers, Assistant Director: Student Life, said: “To have the students back on campus supporting their teams was incredible; this event will become bigger and better every year.”

With the Eco-vehicle race project, the UFS aims to use an innovative skills development approach that will enable students to develop basic knowledge and skills on sustainable energy.

This year, 130 undergraduate students enrolled for this co-curricular skills programme that runs for nine months and culminates in the Eco-vehicle race. A total of eight teams competed in the energy efficiency race, speed race, obstacle course race, and the main event – the endurance race. For the first time in the main event, the teams raced against each other for 18 laps. 

The winners of this year’s event were Central College (Akasia, Karee, Kagiso, Soetdoring, and Wag-’n-Bietjie residences) for Spirit Cup, South Campus took home the Pit Stop, North College won the Smart Lap, and South College won the Endurance Race. The overall winners of the Eco-vehicle race were East College (Legatum residence). 

The driver for East College, Lebakeng Motlotlo, said: “Even though I have always been part of the KovsieACT Committee in my residence, seeing that the focus this year was more on energy saving and saving resources, it pushed me to participate.”

Motlotlo believes the practice he and his team went through worked for them, as they were able to practise “how to turn, slow down around corners, and save energy”. 

“Our team was very dedicated and knew how to improvise when faced with challenges. As a small residence and most of us living off campus, the race taught us the importance of teamwork.” 

Motlotlo believes “initiatives such as the Eco-vehicle race are important, as we learn other skills outside of lectures, which we sometimes think are not important”.

Scheepers said the plan is to “grow the programme, motivate other universities to also invest in their students through this programme, and race to become a national and maybe an international event”.

“The programme adds value to the student experience to ensure that they do not only obtain a degree during their study period, but also undergo practical application of acquired knowledge and skills through real-life situations and meaningful learning encounters,” said Scheepers.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
