Yoga

Are you always anxious and exhausted? Consider for a moment what you can do to break your hectic routine. Maybe stay in bed and binge-watch a series? Or what about joining a yoga class? Let us imagine for a moment that you have opted for the latter. What could possibly be the results of such a choice?

According to Psychology Today, there is a growing body of research to back up yoga’s mental health benefits. “Yoga increases body awareness, relieves stress, reduces muscle tension, strain and inflammation, sharpens attention and concentration, and calms and centres the nervous system.”

Since the beginning of the year, a group of students has been practising yoga on the lawns of the Bloemfontein Campus at the University of the Free State (UFS). At first the group comprised students from the Office for International Affairs’ Umoja Buddy Programme, but it has since expanded to include the general student population.

Strength and stamina from body to mind 
They call themselves “"Yoga Yodas”. Their instructor, Dominique de Kock, says she has witnessed an increased level of calmness and relaxation among the group, which has had a positive effect on their academic performance and mental wellbeing.

Given the anxiety academics can create among some students, yoga is a proven method of achieving a state of positive mindfulness. “Yoga is great for when you are stressed out. Give yourself an hour to just be at peace, relax your mind and practise meditation which is not spiritually tied to any religion,” says De Kock.

Mental health and self-care go hand in hand. Find out more on yoga's positive benefits on mental health and wellbeing, by watching the video below:

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
