Welcome to the third issue of, RE.SEARCH, which is available on the University of Pretoria’s (UP) dedicated science communication platform, Research Matters.
The first two issues looked at ‘Sustainability’ and ‘Innovation’. Issue 3 looks at how we can ‘Renew’ our ways of thinking and grow possibilities. This edition features research that should excite everyone from the Beyhive to forensic pathology enthusiasts to understanding new ways of work. It is now available.
The idea of renewal has come to the fore strongly in a post-COVID-19 pandemic world where we have had to rapidly rethink and revitalise our ways of working, thinking and being.
On a daily basis our researchers are working on ways to renew and rethink the world. In this magazine, we highlight a small portion of some of the knowledge we produce and a cross section of some new ways of thinking about old problems.
Our cover image symbolises this by showing that a leaf is not always a leaf.
A renewed way of thinking about a leaf is when it’s viewed as a highly-efficient organic solar cell.
Learning from nature is just one of the ways in which we can renew our thinking and reimagine our future. You can read more about how our researchers are using nature as a guide for renewable energy by developing organic solar cells – providing cost-effective, efficient and sustainable energy.

In a first for precision agriculture, University of Pretoria (UP) researchers, in association with collaborators from the Council for Scientific and Industrial Research (CSIR), have produced maps of smallholder farms in Gauteng that highlight maize plants in green and weeds in red. The maps were shared with farmers to enable them to pinpoint and eradicate weeds with more precision.
Farmers not only save time and money by cutting down the cost and effort required to manage weeds, but also limit the environmental impact of using harmful weed-killing chemicals by using satellite data and imagery.
This classification map shows the different types of plants in a crop field in various areas in Gauteng. The legend shows red for weeds, green for maize and yellow for mixed growth areas.
