Answer is blowing in the wind

When Attie Jonker's mathematics and science teacher father started building gliders in the garage he could not have known that he was sparking a lifelong passion in his son. Jonker, senior lecturer at North West University, says his mission in life became building a high-performance glider and, as a teenager, he attended Potchefstroom University (now the North West University) and obtained a degree in mechanical engineering.

Fresh, fruity and fleshy

Fresh fruit remains at the centre of most healthy diets. Apples, oranges, apricots, pears, in fact, anything that one can eat fresh has health benefits to the consumer. And fresh fruit exports represent more than 7% of South Africa's export with its largest trading partner, the European Union. South African fruit is highly sought-after overseas.

Impelling images

Image processing is being developed around the world for the manufacturing environment, but a South African research team is pushing the boundaries and finding ways in which the technology can be used to provide better healthcare. Professor Tshilidzi Marwala, the chair of systems engineering at the University of the Witwatersrand, says his passion for science became deep-rooted when he won the National Youth Science Olympiad in 1989.

Catalysts of change

As a schoolboy Jack Fletcher had an intense interest in pure science, but when he went to university he signed up for a degree in chemical engineering instead of the love of his life -- physics. Fletcher, who is now professor of chemical engineering at the University of Cape Town says there were no job prospects for physicists.

Playing the information game

Switching used to be something you did with a fellow player's cards when he left the game for a visit to the bathroom. Nowadays this term has technological significance beyond anything the everyday consumer might consider relevant, yet the results thereof touch every life, every day.

Low-cost energy answer in rural areas

Rural areas -- in any country -- have always presented a challenge to both the inhabitants and local government in terms of infrastructure and services. This makes economic viability of these areas difficult to achieve. But in South Africa no one is ­sitting still when it comes to ­finding alternatives to conventional ­infrastructural delivery -- whether in the area of telephony, internet access or power ­generation.

Diagnostic imaging is here

The practice of modern medicine is a far cry from the staid old family physician with the white coat. In fact, doctors wearing white coats these days are the exception, not the rule. Even hospital doctors are more relaxed these days -- and portray this to their patients, with positive psychological effects. Technology has had a hand in this and today, as opposed to the past, most things are measurable, detectable, imageable.

Fuel cells for the future

The future is green -- or that is the plan. All over the globe answers are being sought and many have been found already that will reduce carbon emissions, reduce the use of toxic substances and promote overall environmental safety while meeting the increasing needs of growing populations in the developing world.

Growing wood from burning trees

Forestry is a topic that doesn't often make headlines -- except when runaway fires destroy thousands of trees, as happened recently across the country on a large scale, in what was described as the worst forest fires in South African history. More than 50 000ha of commercial plantations were destroyed (and another 18 000ha in Swaziland). The cost to timber companies ran into hundreds of millions of rands.
