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.

Nano research at the UFS opens door to smart drugs
2011-06-27

 

Prof. Lodewyk Kock, outstanding professor in our Department of Microbial, Biochemical and Food Biotechnology

Novel antifungal, anticancer and anti-malaria drugs that have been identified in the research of Prof. Lodewyk Kock, outstanding professor in the Department of Microbial, Biochemical and Food Biotechnology at our university, will be disclosed later this year at major international conferences in Asia, Europe and the USA. Prof. Kock will be the keynote speaker at these conferences. 

His presentations will be based on the department’s discovery of yeast assays linked to a new nanotechnology for medicine. The assays were recently discovered by his group and can be applied in the development of novel antifungal, anticancer and anti-malaria drugs.
 
Prof. Kock’s focused research at the university, which now also includes his novel nanotechnology for Biology, began in 1982 in collaboration with Prof. Pieter van Wyk (Centre for Microscopy). He recently collaborated with Prof. Hendrik Swart (Department of Physics).
 
Prof. Kock says the development of novel anti-malaria drugs in particular is getting attention across the world due to the high rates of morbidity and mortality caused by the disease worldwide. Approximately 225 million people are infected annually and about a million (many in Africa) die each year. “Many potential smart drugs have been identified with this research and should now be tested further,” says Kock.
  
These new drugs will be disclosed during Prof. Kock’s keynote addresses at the International Conference and Exhibition on Pharmaceutical Regulatory Affairs in Baltimore, USA, from 6 to 7 September 2011, the Medichem 2011 in Beijing, China from 9 to 11 August 2011 and the XVI Congress of European Mycologists in Greece, from 19 to 23 September 2011.
