Navil Hill Planetarium
At the Naval Hill Planetarium, one of only two in the world that is located in a game reserve in the middle of a city, are from the left, front: Bishop Billyboy Ramahlele, Director of Community Engagement, Tony Horn, Dr Molapo Qhobela, Dorah Klaas from UFS Institutional Advancement, Motheo Leeuw, and Prof Matie Hoffman.

Just over 11 years ago, the University of the Free State (UFS), the Mangaung Metro Municipality, and the Department of Small Business Development, Tourism and Environmental Affairs (DESTEA) signed a Memorandum of Understanding that focused on the development and establishment of the Naval Hill Planetarium. In 2016, the partnership was extended to include the establishment of a facility for environmental education adjacent to the planetarium. Thus, the site on Naval Hill, Bloemfontein is now the Centre for Earth and Space.

Recently, colleagues from the UFS and DESTEA, as well as Free State tourism entrepreneurs, gathered at the planetarium and Boyden Observatory to discuss the next step in this partnership – a collaboration to bring astro-tourism to the Free State.

 

Astro-tourism facilities

Tourism Registrar at DESTEA, Motheo Leeuw, said in his welcome address that,in order to increase the number of visitors to the Free State, it is important to work together. “We are creating a new product, that of astro-tourism,” he stated, and requested the tour guides who attended the event to develop an innovative new product for their market.

Speaking on behalf of the UFS, Dr Molapo Qhobela, Vice-Rector: Institutional Change, Strategic Partnerships and Societal Impact, stated that astro-tourism holds enormous potential for this country. He said the UFS is excited to be a partner in this initiative.

Dr Qhobela said he believes the beauty of science can be used to promote astro-tourism. He echoed Leeuw’s sentiment, stating that it is only through partnerships that astro-tourism will become a reality. “If we want to drive astro-tourism, we need to find creative ways to connect with each other,” he stated.

“We must work together to make our home, Bloemfontein, a better place,” he said.

 

A taste of astro-tourism

About 30 delegates, including the UFS, DESTEA, military representatives, and tour guides from Bloemfontein and Clarence, gained first-hand experience of the potential of astro-tourism. They attended a full-dome pre-rendered astronomy show and a presentation on the night sky in the Naval Hill Planetarium, where images were projected onto the planetarium dome, resulting in an immersive experience of the wonder of the universe. The tour guides proceeded on a game drive in the Franklin Game Reserve on Naval Hill.

Later in the afternoon – after enjoying a sunset view of the environment at the Boyden Observatory – guests were introduced to the observatory, including its telescopes and the Astronomy Museum. Prof Matie Hoffman, Dr Mart-Mari Duvehage, and Dawid van Jaarsveldt from the Department of Physics at the UFS, were on hand to conduct the tour of the observatory, and Bishop Billyboy Ramahlele, Director of Community Engagement, hosted the guests.

Tony Horn, a tour guide from Bush Junkies Adventure Safaris – one of the guests at the event – is optimistic about the potential of this initiative. He said he will bring visitors to Boyden and the planetarium to experience the attractions.

 

The Two-Observatories Project

The Boyden Observatory and the Naval Hill Planetarium are known as the Two-Observatories Project, which will be the focus of astro-tourism in the Free State. Focus areas of the Two Observatories Project are science communication and education, research, astronomy heritage, and the environment. The project therefore has great potential to attract tourists.

According to Prof Hoffman, the two observatories work in synergy to educate and inform citizens about the natural sciences. They are also important for the display of and communication about South Africa’s astronomical heritage.

In addition to being an active optical research site, Boyden Observatory is ideal for public lectures and star-gazing events. Educational programmes, including observations with telescopes, are also presented at the observatory. An astronomy museum is a major attraction at Boyden.

The Naval Hill Planetarium, also a good venue for public lectures and concerts, offers planetarium shows, including full-dome films. The site also offers a large hall that is primarily used for environmental education. These facilities operate under the banner of the Free State Centre for Earth and Space.

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.
