In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos. 

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece. 

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy. 

By the time of this writing, the livestream has reached more than 50 000 people.

The interdisciplinary field that develops methods and software tools to understand biological data is known as bioinformatics. According to Dr Renée Prins, a research fellow in the Department of Plant Sciences at the University of the Free State, there are few tertiary institutions in South Africa that offer a postgraduate degree in Bioinformatics.

“Most institutions focus either on humans, human diseases, forest trees and their pathogens.  They usually do not have spare capacity to assist researchers, for instance, those working on crops in the agricultural sector,” Dr Prins said.

Big data sets need significant skills

With the advancements made in genomics such as high throughput DNA marker platforms and next-generation sequencing technologies, the data sets biologists have to deal with have grown massively big and cannot be dealt with unless you have significant computer skills.

Dr Prins believes that all young researchers need some level of training in this field to be effective in future. The British Council Researcher Links, being run by the Newton Fund, gives early career researchers across selected partner countries the opportunity to form international connections through fully funded workshops and travel grants. Dr Prins made use of this opportunity and with the assistance of the Department of Research Development at the UFS, she arranged for Dr Diane Saunders of the John Innes Centre in the UK, a bioinformatician of note, to present training to a group of 20 early career researchers in Worcester in the UK.

Providing training with Dr Saunders were two other bioinformaticians from the UK, Dr Burkhard Steuernagel (John Innes Centre) and Dr Robert Davey (Earlham Institute). From the UFS side, Eleanor van der Westhuizen and Dr Henriëtte van den Berg (former UFS academic) acted as mentors, providing guidance on funding opportunities and career development skills.

Participating in projects in a global context
The researchers attending the training came from research institutions or academia, and they work involving plants (predominantly wheat) or plant pathogens. A limited number of participants from the commercial sector, including private South African companies focusing on plant breeding and molecular genetics lab work on agriculturally important crops also benefited from the training. 

“Tertiary institutions in South Africa have the obligation to ensure that young scientists are equipped with bioinformatics skills. If they are not equipped with the necessary skills, they will not be able to participate in research projects that are relevant in a global context,” said Dr Prins.
