Young researcher to jet out to UK

When Mamosa Ngcala jets out to the United Kingdom (UK) on 31 July 2018, she will not only be doing research and improving herself academically at the Durham University, but she will also put yet another feather in the growing research profile cap of the Qwaqwa Campus.

“I am looking forward to my study visit under the mentorship of Dr Steve Chivasa, my supervisor’s co-researcher in the Department of Biosciences at the renowned Durham University. This will enable me to grow academically as much as it will get me closer to concluding my research on climate change and food security,” said Mamosa, a master’s student in Science (Botany). Her supervisor is Dr Rudo Ngara.

“Going there will fast-track my research that looks at how food security can be enhanced in as far as growing sorghum is concerned. This study in Plant Biotechnology aims to identify heat responsive genes in sorghum, which is the fifth most important cereal crop in the world. The information obtained in this study will serve as fundamental knowledge regarding molecular responses of plants to heat stress and will be used in breeding programmes to develop crops that can tolerate high temperature stress conditions caused by climate change, thus resulting in high crop yield in agriculture as well as food security,” she said. She will be in the UK until 12 September 2018.

Mamosa has recently won the 3-Minute thesis competition for graduates that was part of the ‘Sorghum in the 21st Century’ international conference held in Cape Town.

Talking about this achievement, she said: “Going head-to-head with PhD students from all over the world gave me extra motivation and drive to do well, and I did. This goes to show that we can achieve whatever we put our minds to. Having to summarise my entire study in three minutes for a non-specialist audience, using one PowerPoint slide, was a challenge that had to be overcome,” said Mamosa. The conference was organised by the Collaborative Research on Sorghum and Millet and the University of Pretoria.

Mamosa graduated with distinction in Botany for her honours degree. She is a member of the Golden Key International Honour Society and Chairperson of the Postgraduate Student Council and is looking forward to advancing her studies to PhD level.

What do diamonds, chocolates, bugs and almost 30 Nobel Prizes have in common? Crystallography
2014-10-15

 

Some of the keynote speakers and chairpersons at the third world summit in the International Year of Crystallography (in Africa) were, from the left, front: Profs Abdelmalek Thalal (Morocco), Prosper Kanyankogote (University of Kinshasa, Democratic Republic of the Congo); Habib Bougzala (Tunisia), Santiago Garcia-Granda (IUCr, University Oviedo, Spain), Michele Zema (IYCr 2014, Italy/UK) and Dr Jean-Paul Ngome-Abiaga (UNESCO, Paris, France); back: Dr Thomas Auf der Heyde (Acting Director-general, South African Department of Science and Technology); Dr Petrie Steynberg (SASOL) and Prof André Roodt (UFS, host).

The third world summit in the International Year of Crystallography (in Africa) was hosted by Prof André Roodt, Head of the Department of Chemistry and President of the European Crystallographic Association,  at the University of the Free State in Bloemfontein.

A declaration with and appeal to support crystallography and science across Africa, was signed.

When one mentions 'Crystallography', or more simply 'crystals', what comes to mind? Diamonds? Perhaps jewellery in general? When thinking of crystals and Crystallography, you will need to think much bigger. And further – even to Mars and back.

Crystallography refers to the branch of science that is concerned with structure and properties of crystals. The obvious examples would include cut diamonds, gemstones such as amethysts, and ‘simple’ crystals such as selenite and quartz.

But have you thought about the irritating brown scales at the bottom of your kettle? The sand in your shoes? The salt over your lamb chops or the sugar in your coffee? All crystals. From egg shells to glucose, from bugs and insecticides to additives in food – even the compounds in chocolate – all fall under the close scrutiny of Crystallography.

The breakthroughs this field of science has produced have led to almost 30 Nobel Prizes over the years.

Determining the structure of DNA by crystallography was arguably one of the most significant scientific events of the 20th century. Different diseases have been cured or slowed by medicines obtained based on crystallographic studies. These include certain cancers, HIV/Aids, Tuberculosis and Malaria. Biological Crystallography enables the development of anti-viral drugs and vaccines.

This field of science influences our daily lives in virtually immeasurable ways. Here are but a few areas of study and development Crystallography contributes to:

•    LCD displays;
•    cellular smartphones;
•    insects and insecticides;
•    additives and products in foods;
•    improved effectiveness and security of credit cards;
•    new materials to preserve energy;
•    better gasoline with less by-products;
•    identify colour pigments used in paintings from the old masters, indicating if it’s an original or an imitation; and
•    beauty products such as nail polish, sun-block, mascara and eye shadow.

Crystallography is also currently used by the Curiosity Rover to analyse the substances and minerals on Mars.

Crystals and Crystallography form an integrated part of our daily lives – from bones and teeth to medicines and viruses, from chocolates to the blades in airplane turbines. Even down to the humble snowflake.
