Science ambassadors
Friends Tekano Mbonani and Chaka Mofokeng are pursuing graduate degrees in respectively Physics at the University of the Free State (UFS) and Astronomy at the University of the Western Cape. The two got together and decided to reach out to the high school, Leseding Technical Secondary School, where they came from.
It was a full house as more than 120 learners packed the hall at the Leseding Technical Secondary School in the Free State, where two young Astronomy researchers had come home to tell their younger peers about their studies and career prospects across South Africa.

Chaka Mofokeng and Tekano Mbonani are both former learners at the high school. Currently pursuing graduate degrees – for Mbonani in Physics at the University of the Free State (UFS), and for Mofokeng in Astronomy at the University of the Western Cape – the two friends got together and decided to reach out to the high school where they came from.

The event took place in January before schoolwork, tests, and exam preparations are occupying learners’ minds, inviting them to think about the big picture – the future, and how to be part of it. This is timely, because in July last year, the MeerKAT radio telescope was inaugurated in the Karoo. The MeerKAT is the first step to the international SKA telescope project, but it is already one of the best radio telescopes in the world and has placed South Africa firmly on the world map of radio astronomy and engineering.

Building a bridge
“This project enables us to build a bridge between secondary and tertiary institutions. Currently focused on senior secondary students, we aim to promote science through outreach events and activities. Using science and technology-based activities and events, such as stargazing at an observatory or exploring the universe in a planetarium, we want to attract these future secondary graduates. We also provide mentorship, hoping to help them improve their academic performance in matric,” said Mbonani.

For a whole morning, they spoke about their journeys, about science, about the skills that scientists acquire during their studies and all the opportunities such studies open up in an era where the 4th Industrial Revolution is predicted to reduce the number of jobs in many traditional professions. They addressed their peers in both English and Sesotho.

Astronomy in South Africa contributes to critical-skills development. Investing in the MeerKAT, for example, meant that over a thousand bursaries were made available through the SKA South Africa Human Capacity Development programme. Young scientists like Mofokeng and Mbonani have the opportunity to be part of MeerKAT science projects through their studies, using machine learning and other skills that are high in demand in today’s world. This was one of the messages they brought home.

Gaining new skills
“As an Astronomy research student, I have gained skills such as data analysis, mathematical modelling, communication and writing, programming, and teamwork, among others. These are requirements for most companies and institutions. With the unfolding of the 4th Industrial Revolution, such skills sets make young and aspiring scientists the perfect candidates for making the most of future opportunities,” reflected Mofokeng.

Most of the learners said they have never attended a science-outreach event. They were inspired by the young scientists’ stories and nearly half of them said they could see themselves pursuing a career in science. The learners also expressed a strong interest in more events of this kind, as well as mentorship during Grades 11 and 12 from peers at university. They asked about the salaries earned by astronomers, how long the studies take, and where astronomers are working in South Africa.

This initiative, started by two bright young scientists, hopefully marks the beginning of many more events of this kind. Mofokeng and Mbonani are already planning what to do on their next trip home.

The conservation strategy of the black rhino in Africa needs to change in order to protect the species from extinction, a group of international researchers has found. The study that was published in the Nature Scientific Reports reveals that the species has lost an astonishing 69% of its genetic variation. 

South African researchers took part 
The researchers, which included local researchers from the National Zoological Gardens of South Africa (NZG), have highlighted the fact that this means the black rhino is on the brink of extinction. "We have found that there is a decline in genetic diversity, with 44 of 64 genetic lineages no longer existing," said Prof Antoinette Kotze, the Manager of Research and Scientific Services at the Zoo in Pretoria. She is also affiliate Professor in the Department of Genetics at the University of the Free State and has been involved in rhino research in South Africa since the early 2000s.  

DNA from museums and the wild 
The study compared DNA from specimens in museums around the world, which originated in the different regions of Africa, to the DNA of live wild animals. The DNA was extracted from the skin of museum specimen and from tissue and faecal samples from animals in the wild. The research used the mitochondrial genome.

"The rhino poaching ‘pandemic’
needs to be defeated, because
it puts further strain on the genetic
diversity of the black rhino.”


Ability to adapt 
Dr Desire Dalton, one of the collaborators in the paper and a senior researcher at the NZG, said the loss of genetic diversity may compromise the rhinos’ ability to adapt to climate change. The study further underlined that two distinct populations now exists on either side of the Zambezi River. Dr Dalton said these definite populations need to be managed separately in order to conserve their genetic diversity. The study found that although the data suggests that the future is bleak for the black rhinoceros, the researchers did identify populations of priority for conservation, which might offer a better chance of preventing the species from total extinction. However, it stressed that the rhino poaching ‘pandemic’ needs to be defeated, because it puts further strain on the genetic diversity of the black rhino. 

Extinct in many African countries 
The research report further said that black rhino had been hunted and poached to extinction in many parts of Africa, such as Nigeria, Chad, Cameroon, Sudan, and Ethiopia. These rhino are now only found in five African countries. They are Tanzania, Zimbabwe, Kenya, Namibia, and South Africa, where the majority of the animals can be found.
