Dr Nthatisi Nyembe, a faculty member in the Department of Zoology and Entomology at the University of the Free State (UFS) Qwaqwa Campus, is making notable advancements in the field of parasitology. A native of Qwaqwa, Dr Nyembe embodies the potential for academic achievement within the community she serves, representing a commendable instance of homegrown talent.

A respected graduate of the UFS, Dr Nyembe completed her Bachelor of Science degree in Botany expeditiously before pursuing a Bachelor of Science Honours and Master of Science in Zoology, specialising in Parasitology, all on the UFS Qwaqwa Campus. Her postgraduate studies centred on evaluating medicinal plants for compounds with the potential to treat parasitic gastrointestinal nematodes in sheep – an area of significant importance for the sustained well-being of livestock.

Dr Nyembe broadened her academic horizons by earning a Doctor of Philosophy in Animal and Food Hygiene from the Obihiro University of Agriculture and Veterinary Medicine in Hokkaido, Japan. Her doctoral studies widened her scientific understanding and enhanced her expertise in the treatment of parasitic ailments.

Currently, her research focuses on the evaluation of naturally derived substances, synthesised compounds, and nanoscale particles for their potential efficacy in combating parasitic illnesses. Her broader research interests include pharmacological evaluation, the diagnosis and epidemiology of diseases transmissible from animals to humans, cell biology, and animal management, making her contributions essential to both human and veterinary medicine.

Her academic and research background is extensive. She has held research assistant positions at both the Obihiro University and the UFS, and she also concluded a postdoctoral fellowship at the North-West University in the North West province of South Africa.

Beyond her scholarly pursuits, Dr Nyembe engages in activities such as skiing, travelling, reading, and community involvement, reflecting a well-developed character and a commitment to creating a positive impact beyond the academic sphere.

With her international academic experience and firm local connections, Dr Nyembe continues to be a symbol of distinction, inspiring students and contributing to pioneering research that addresses practical challenges.

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.
