Jana Scholtz, goal defender and playing in her first year as a regular starter, has been a solid performer for the Kovsie netball team in Varsity Netball.

The building blocks are starting to form a solid basis from where Kovsies can launch an attack to defend the Varsity Netball title they won in 2018. This is according to Karin Venter, one of the team’s assistant coaches.

After losing their first encounter to Tuks, they registered wins over the University of Johannesburg, Tshwane University of Technology, and the North-West University. The match against the Maties in Bloemfontein on 23 September 2019 – the last in the group stage, should determine which of the two teams will book a home semi-final along with Tuks.

“Yes, that is the crucial one,” said Venter, the team’s defensive coach. Her counterpart at the Maties is Adéle Niemand, with whom Venter combined as defenders at Kovsies for several matches in the mid-2000s. Apart from the Maties, the women of the University of the Free State still have to face the Madibaz and the University of the Western Cape (both in Pretoria on 15 and 16 September 2019).

“The combinations are starting to form a unit and our confidence is on the increase. Now we are looking for consistency in our performances.”

According to Venter, they were hit hard by goalkeeper Ané Retief’s injury, which kept her out of the first two matches. This meant that they had to start against Tuks with a first-year student, Chanel Vrey.

“It was tough, but I’m impressed with the way in which she, Ancia Pienaar, and Jana Scholtz – who are all youngsters – stepped up.”

Venter is responsible for the analyses and recons to assist players.

“The programme we are using provides us with all the required footage. You can make notes on it and send these clips to players, which means you don’t have to sit next to a player to explain something. We also provide them with notes and sketches of opponents’ playing patterns, which they must work through as part of their preparation.”

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
