Are you the next 3MT South Africa winner?

15 July 2021 | Story Lunga Luthuli

The Three-Minute Thesis Competition, also known as the ‘3MT’, is an annual competition held at 200 universities around the world. It is open to PhD and master’s students, challenging participants to present their research in just 180 seconds – in a way that is understood by an audience with no background in the research area.

The competition originated at the University of Queensland, Australia. The UFS Postgraduate School was the first to bring the ‘Three-Minute Thesis’ (3MT) competition to Africa, and it has now become an annual event at the UFS.

The competition aims to assist participants in the development of presentation, research, and academic communication skills, as well as to support the development of research students.

Each faculty will run the 3MT at faculty level. Winners from each faculty will compete against each other during the institutional competition on 1 October 2021 and will stand a chance to win these awesome cash prizes.

UFS INSTITUTIONAL PRIZES FOR 2021 ARE:

Position	Prizes 2021
Master’s winner	R6 000
Master’s 1^st runner-up	R4 000
Master’s 2^nd runner-up	R2 000
PhD winner	R8 000
PhD 1^st runner-up	R6 000
PhD 2^nd runner-up	R4 000

Winners of the institutional competition will go ahead to compete against other universities on 29 October 2021.

Scientists discover a water reservoir beneath the Free State

2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
