Think three minutes is a long time
One slide and three minutes was all they had to present their research.

It may take three minutes to make noodles, but imagine presenting the 80 000-word research you spent months writing in just three minutes.

For master’s and PhD students participating in the annual institutional Three-Minute Thesis (3MT) competition at the University of the Free State (UFS), three minutes seem to go as fast as three seconds. Each participant is given three minutes to present the essence of their research, explaining the problem, methodology used, as well as the importance of their research using one slide.

A jubilant audience of staff members and students gathered at the Equitas Auditorium on the Bloemfontein Campus for the annual institutional 3MT competition. Interesting research topics across different fields of study, which the participants had spent months and even years researching, were presented in the master’s and PhD categories. After each presentation, a panel of judges and the audience had the chance to ask the participants questions on their research.

The competition is part of the initiative by the UFS Postgraduate School to showcase postgraduate research across disciplines, faculties, and universities. Participation in this competition helps to develop academic, presentation, and research communication skills to ensure that research students can effectively communicate their research in a language that even non-specialists can understand. 

It is the mandate of the school to “create an enabling environment for postgraduate students to excel in their pursuit of their academic quests”, according to Prof Witness Mudzi: Director of the UFS Postgraduate School. 

Winners at the event:

PhDs
• Third prize: Trudie Strauss - Babelish Confusion: Finding Statistical Structure in the Diversity of Languages (R3 000 cash prize)
• People’s choice: Nokuthula Tlalajoe - The transition of undergraduate first-year students into the MBChB programme: Social learning and integration

Master’s
• First prize: Phuthi Samuel Masingi   Physical demands of South African Football (R6 000 cash prize)
• Second prize and people’s choice: Nigel Masalla   “ Stealthing” – lifting the veil on non-consensual condom removal (R4 000 cash prize)
• Third prize: Vuyisa Sigwela - Extraction, characterisation and application of betalains from beetroot, cactus pear and amaranth (R2 000 cash prize)

The UFS will be represented by Trudie Strauss at the national 3MT competition on 26 October 2018. The national competition will take place on the UFS Bloemfontein Campus

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.
