The contents of a special issue of Quaternary International (QI), consisting of 13 articles and contributions by 45 authors (25 from abroad), was recently presented to Dr James Simpson Brink. The papers represent the broad range of topics covered by Dr Brink’s research interests.  

The special issue of QI was initiated to coincide with James Simpson Brink’s 60th birthday after he recently celebrated 35 years of ground-breaking research at the National Museum of Bloemfontein.

Dr Brink is affiliated to the Centre for Environmental Management at the University of the Free State (UFS).

Prof Louis Scott, researcher in the Department of Plant Sciences at the UFS, was the executive guest editor, and was part of a team of three guest editors (Dr Liora Horwitz from the Hebrew University in Jerusalem, and Dr Daryl Codron from the National Museum in Bloemfontein) who worked on this special issue of the journal, QI. 

In honour of a friend and colleague
“Dr Brink made contributions to osteology, Quaternary palaeontology, and archaeozoology, by investigating the environments and mechanisms that drove the evolution of mammal communities of southern Africa,” said the guest editors. 

“By studying the morphology of the endemic black wildebeest he demonstrated how the species evolved in the central interior of South Africa. He pioneered descriptions and dating of faunal assemblages that make up the so-called ‘Cornelian’ and ‘Florisian’ Land Mammal Ages. In this way he reconstructed the long history of environments in which Stone Age occupants survived in the region. The work included the age determination of the cranium with facial bones of an individual who lived at Floribad around 250 000 years ago.

Work enabled more important studies
“Dr Brink contributed more than purely academic insights in that he built and curated the modern mammal and fossil faunal collections of the Florisbad Quaternary Research Station. These collections made it possible for researchers, who came from all over the world, to visit the Free State and focus on spatial and temporal palaeoenvironmental trends. Apart from contributing to the functional diversity of mammalian species, this enabled the investigation of morphological and behavioural variations across populations and communities,” said the editors.

The topics of the papers in this special issue of QI are interdisciplinary and include different methods in archaeology, vertebrate palaeontology and past (or palaeo-) environmental reconstruction. The ages dealt with range from the relatively recent Iron Age to the Oldowan period, which is over a million years old.

According to Prof Scott, with a degree of overlap in the interdisciplinary fields studied, the papers can be arranged into 1) taphonomy and archaeozoology, relating to the processes resulting in the formation and preservation of fossil material in archaeological sites, 2) Stone Age archaeology, dealing with artefacts, stratigraphy and palaeoanthropology, and 3) palaeoecology, that includes palaeontology, isotope studies and palaeoenvironmental reconstructions.

The journal, published by Elsevier, will be distributed worldwide.

Student receives international award in microbiology
2008-01-24

A postgraduate student at the University of the Free State (UFS) received an exceptional honour last month when he received the first prize for his presentation in the Biochemistry and Industrial Mycology session of the Asian Mycology Congress (AMC) held in Malaysia.

Desmond Ncango (24), a Ph.D. student from the Department of Microbial, Biochemical and Food Biotechnology received the first prize for his presentation on the inhibitory effects of non-steroidal anti inflammatory drugs (NSAIDs) such as aspirin on fungi.

This suggests that commonly used aspirin may be used as a cheap antifungal to combat yeast infections. Desmond also exposed novel lubricants that are used by yeasts for water-propelled movement. This may find application in nanotechnology in the lubrication of nanorobots, which are manmade miniature machines, invisible to the naked eye, which may in future be used to combat diseases such as cancer.

The conference, which was attended by more than 300 representatives from 27 countries, is a platform for mycologists (who are experts in fungi) around the world to come together and share their knowledge and research. “Many interested researchers listened to my presentation and were impressed by the novelty and scientific depth of my work,” said Desmond.

“The presentation was selected as the best because of its novelty, academic depth as well as applicability. The meticulous preparation and presentation style also contributed to the success,” said Prof. Lodewyk Kock, head of the Lipid Biotechnology Group at the department and main promoter of Desmond’s Ph.D. studies.

“I cannot really explain the feeling when my presentation was selected as the best as it was presented in a very difficult category and many senior researchers and professors also participated. I plan to use all the knowledge and skills I have learnt from Prof. Kock, who is my role model, especially to the benefit of disadvantage communities in South Africa. I want to follow an academic career at a tertiary institution when I have completed my Ph.D. studies,” said Desmond.

Desmond went to school in Botshabelo, Bloemfontein and completed his Grade 12 in 2000 with a distinction in Mathematics. He enrolled for a B.Sc. degree at the UFS, majoring in Microbiology and Physiology. After obtaining this qualification, he joined the postgraduate research group of Prof. Kock. He completed his M.Sc. degree with distinction last year and was privileged to have this research published in and on the cover of the Canadian Journal of Microbiology, a journal accredited by the Institute for Scientific Information (ISI).

He was one of six postgraduate students from the Lipid Biotechnology Group who attended the AMC conference in Malaysia. The students’ attendance was funded by the South African Fryer Oil Initiative (SAFOI), which is housed in the UFS Department of Microbial, Biochemical and Food Biotechnology. This initiative, steered by Prof. Kock, currently monitors edible oils in the food industry in South Africa and makes a quality seal available to the manufacturers and distributors of these edible oils.

“SAFOI’s income is used to fund my own research on various kinds of oils (including yeast oils) to enable postgraduate students to attend international congresses and to partially fund international scientific symposia and congresses,” said Prof. Kock.
