Science Oscars Winners 2024
From top-left to right: Drs Claudia Ntsapi, Mpho Mafa, Angélique Lewies, Yolandi Schoeman, and Bimo Nkhata are dedicated to innovative solutions spanning from addressing brain aging to enhancing food security, developing xenograft scaffolds for regenerative medicine, transforming degraded terrains into vibrant landscapes, and protecting precious water resources. Prof Sandy-Lynn Steenhuisen's research team investigates the dynamics of mountain ecosystems in terms of pollination, seed dispersal and other aspects of plant reproductive ecology and vegetation community, largely assessing the impacts of climate change and invasive alien plants on these systems.

A neuropsychologist, a biochemist, a cell biologist, and an ecological engineer from the University of the Free State (UFS) have all received their first nomination in this year’s NSTF-South32 Awards. The four researchers have been nominated in the TW Kambule-NSTF Award: Emerging Researcher category.

These emerging researchers are part of a group of nine UFS researchers nominated for the ‘Science Oscars of South Africa’. Two other researchers; Prof Sandy-Lynn Steenhuisen, Associate Professor and Subject Head: Department of Plant Sciences and the Afromontane Research Unit (ARU), and Dr Bimo Abraham Nkhata, Senior Lecturer at the UFS Centre for Environmental Management (CEM), have also been nominated in the categories Green Economy and NSTF-Water Research Commission (WRC) respectively.

Preserving human brain health with age

Dr Claudia Ntsapi, who is passionate about exploring innovative solutions to address the gradual decline in normal brain function associated with aging, says the research that led to her nomination focuses on preserving human brain health to delay or prevent age-related conditions, such as Alzheimer's disease.

The nomination, she says, reaffirms the growing impact of their research efforts and reinforces her commitment to contributing toward enhancing the quality of life for individuals affected by age-related neurodegenerative diseases and their families.

“Leveraging advanced cell-based models that mimic human cellular environments, my research investigates the potential benefits of medicinal plants as supplementary treatments for neurodegenerative diseases. By utilising cutting-edge techniques, such as the innovative CelVivo ClinoStar 2 System, we strive to gain insights into the safety and efficacy of underexplored medicinal plants in preserving cognitive function and slowing disease progression.

“By exploring the untapped potential of bioactive compounds found in medicinal plants and nutraceuticals, our research group aims to contribute to the identification of novel therapeutic targets and the discovery of new avenues for intervention to improve the quality of life for individuals affected by age-related brain conditions,” Dr Ntsapi explains.

Improving food security, and renewable resources for circular economy 

A humbled and excited Dr Mpho Mafa says his nomination is based on the impact and quality of research his group (carbohydrates and enzymology Laboratory: CHEM-Lab) produced since 2020.

“My research group uses biochemical, enzymological, and biotechnological techniques to study the physiological and biochemical functions of carbohydrate-active enzymes (CAZymes) and carbohydrate metabolism during wheat interaction with rust disease-causing fungi or wheat infestation by a virulent Russian wheat aphid (RWA) biotype,” he said.

“The findings from these studies allow us to identify the key genes, enzymes, metabolites and biochemical processes used by wheat plants to reduce the effects of rust fungi or RWA damage, leading to improved plant health and yield. Thus, my research group uses innovative biochemistry/biotechnology approaches to protect the second-most important grain crop in South Africa against rust diseases and aphid attack.”

In addition, Dr Mafa uses the CAZymes in the field of lignocellulosic biorefinery to produce value-added products (VAPs), such as fermentable carbohydrates used in the production of second-generation biofuel for the circular economy. 

“I want to thank the NRF-Thuthuka for funding the lignocellulosic biorefinery project which aims to improve the conversion rate of lignocellulose to VAPs through enzymatic catalysis processes.” Dr Mafa says.

Tissue engineering and regenerative medicine

According to Dr Angélique Lewies, this achievement was truly a team effort from her dedicated colleagues at the Robert WM Frater Cardiovascular Research Centre. She says the nomination validates her team’s hard work and dedication, and recognises their efforts to advance the fields of tissue engineering and regenerative medicine.

“Our team has developed xenograft tissue scaffolds from non-human sources with a reduced potential to induce immune responses in human recipients, which are common causes of calcification, degradation, and failure of surgical scaffolds. We pioneered a processing technique that promotes cell infiltration, remodelling, and regeneration of the tissue. These xenografts are versatile, showing promise for use in various surgical disciplines, including cardiac and plastic surgery,” Dr Lewies says.

Induced pluripotent stem cells created from recipient skin cells, she explains, can be combined with the processed tissue, creating custom tissue products for improved patient-specific outcomes. Their research has successfully developed a method for processing bovine pericardium that not only mitigates calcification but also preserves mechanical properties and enhances host cell infiltration, significantly increasing the longevity of the tissue when used clinically.

Environmental and sustainability challenges

“This nomination is both an honour and an affirmation of the importance of ecological engineering in addressing today’s environmental challenges,” says Dr Yolandi Schoeman.

“It represents a recognition of the value and impact of integrating natural processes with engineering principles to create sustainable and resilient ecosystems whilst addressing some of our most pressing sustainability challenges,” Dr Schoeman says.

Her work primarily revolves around ecological engineering — a field that combines natural processes with engineering principles to address environmental and sustainability challenges. “I lead projects that transform degraded terrains into vibrant, functioning landscapes through bio-intelligent design, essentially converting ecological liabilities into assets. These systems are in many cases designed from microscopic level into mega supercell systems. We've developed over 20 conservation blueprints that integrate these principles at a landscape level, also preparing them for biodiversity financing.”

By founding and institutionalising the Ecological Engineering Institute of Africa (EEIA), the EEIA aims to spread this innovative approach, emphasising the importance of both scientific rigour and ecological viability continent-wide in Africa. The goal is to create sustainable, economically sound, and ecologically robust solutions that not only regenerate but enhance environmental health and resilience for the benefit of ecosystems and communities.

Addressing water challenges in South Africa

Dr Bimo Nkhata sees his nomination as a personal milestone and as a reflection of the importance of the work he is doing to address water challenges in South Africa. The nomination also reinforces his commitment to the cause, and inspires him to strive for even greater achievements in the future, he says.

“My research and work on sustainable water management is of utmost importance for South Africa because the country faces significant water quality challenges due to pollution from various sources, including agriculture, industry, and urbanisation. Sustainable water management practices ensure the availability of sufficient and clean water for various sectors, supporting economic growth, job creation, and poverty alleviation.

“My research and initiatives contribute to protecting and preserving the country’s precious water resources, ensuring they remain clean and safe for both human consumption and ecosystem health,” explains Dr Nkhata.

Ensuring a sustainable future for the earth

For Prof Steenhuisen, this nomination is a humbling experience which will go a long way to highlighting her research group’s research.

“This nomination was certainly not earned alone; I have a fantastic collaborative support team being recognised for all the late nights and monumental efforts of the team is a huge privilege and honour. It will hopefully attract funders and interest to further support our project needs,” she says.

According to her, their research team, dubbed the QPAIR lab for Qwaqwa Plant-Animal Interactions Research lab, investigates the dynamics of mountain ecosystems in terms of pollination, seed dispersal and other aspects of plant reproductive ecology and vegetation community, largely assessing the impacts of climate change and invasive alien plants on these systems.

Prof Steenhuisen says everyone should be working towards ensuring a sustainable future for the earth in terms of conservation of biodiversity and ecosystem services that can lead to food security, resilient ecosystems and healthy human livelihoods. Climate change, the loss of biodiversity due to land degradation and the spread of invasive alien species threaten these services and especially sensitive systems such as those found in our mountains. 

• The awards ceremony will take place on 11 July 2024.

SRC Inauguration speech: 22 January 2005
2005-01-22

Campus Head (Prof Peter Mbati). Dean of Students (Dr Natie Luyt). Deputy Director: Student Affairs and my boss (Mr. Teboho Manchu), Members of the University executive and Academic staff members, SRC members, Leaders of trade Unions and Student organizations, Distinguished guests, Ladies and gentlemen, most importantly first entering students and Parents receive my heartfelt revolutionary greetings.

Let me extend my word of appreciation to our distinguished guests for adding value and dignity to this event. Your presence here means a lot to us. Program Director what I bring here with me, assisted by facts, and is therefore just the work of my imagination. Like a love letter addressed to a sweetheart miles away, even though you do not know how she feels, what she wants to hear, and do not even know how her face looks like.

To me a speech is just an honest and intimate conversation. That is why I got into the habit of establishing a dialogue, or a debate, with my acquaintances looking at their faces and trying to persuade them of what I am telling them.

Mr. Speaker and Madam Deputy Speaker of the Student Parliament we are gathering at this ceremony, significantly few weeks after the release of grade 12 results, with the exception of those from Mpumalanga because of fraud. The Grade 12 results also show that only 18% of Black learners matriculated with exemptions, as compared to 53, 6% of white learners. This is an indication that our education system needs an overhaul.

We are also gathered here significantly a day after the management retreat held in Bloemfontein, Masselspoort. The retreat discussed, among other things, the transformation agenda, and some possible solutions to challenges we are facing now.

Most regrettably, we are gathered here when the whole world morns the victims of Tsunami tragedy. Let me therefore tore the line and convey our deepest condolences, from the last robot of my heart, to the affected families. Our hearts and thoughts will always be occupied by this horrified tragedy.

Creating a new Institution

I would submit, for purposes of debate and discussions that this Institution should strive to specialize and excel in regional rural development studies. Since our higher education, institutions in South Africa are generally weak in rural development studies. Instead, most of them tend to have an urban orientation to their programmes. Training everybody for the cities, big business and the private sector. This is a big weakness in a country with such large rural areas and population trapped in poverty, disease and ignorance.

Women’s studies

Program Director, it is only a moron who can argue against the fact that for us to reposition the institution around the regional development challenge, we need to start first with women empowerment. It is a fact that in most of our poor communities and families, it is women who withstand the worst of poverty. They are the ones who daily have to wipe tears from children who are hungry. It is women who look after the sick, the elderly, those dying from AIDS and the jobless. They are the one who have to fetch water, make fire and cook. There can therefore be no rural development studies without women studies, in particular on how to empower them and assist in the provision of basic services, so that they are relieved from some of the burdensome task of the society.

Registration Process

Mr. Speaker and Madam Deputy Speaker of the Student Parliament let me indicate that the registration is a process and not an event, so it cannot be concluded overnight. This huge process demands for people to stay calm, as there is no crisis. People should stop being excited. At the same time, no organization should use its cheap popularity and unilaterally disrupt the continuous and smooth running of the registration process at hand.

Let me strongly indicate, madam deputy speaker, that I am on record for stating that I have forgiven all those who have wronged us. I harbour no bitterness towards the protagonists of our painful and unfortunate events of the past week. And we will overcome this process not by our own devices but by the help of Almighty God and the grace of our Lord Jesus Christ.

Concerning registration of first years, we have programs, concerning that of senior students, we have programs, regarding graduations we have programs, and concerning HIV\AIDS we have programs. So, there is no need for people to press panicking buttons.

Mr. Speaker and Madam Deputy Speaker of the Student Parliament let me be opportunistic and welcome the entire student body on Campus for the academic year 2005. May our lovely first entering students have a happy and momentous year as part of Qwaqwa Campus of University of the Free State. May your studies be fruitful and enjoyable.

Student years are generally the happiest years of your life, so please make the most of them. While you are doing, all your preparations bear in mind that University is not an opportunity, it is just creating opportunities for a person.

On behalf of SRC members, our people, our students and management members I would like to welcome you all. Even though your parents are far away, here at Uniqwa you have more brothers, more sisters and more parents. Since we will love you with the same love as if we are from one family, and I have no doubts that management members will love and care for you as if you are their own children. Should you encounter any problem while studying at the Qwaqwa Campus of University of the Free State do not hesitate to contact us at the SRC offices because we need to ameliorate any factor influencing you negatively while on campus. I wish you well in the attainment of your academic pursuit.

Senior Students: We are not faced with just a new year but another academic year where we all have to work together to achieve our common goal of building our Institution through the development of human power. I urge you to invest your whole selves in this SRC.

For quite some time now, a debate has been ranging as to, whether has there been any progress in this incorporation process, or we are just moving with no direction. This debate is important, but I hasten to add not essential. The SRC is also involved in this debate, but with definite shift in emphasis. For us it is not important to participate in the debate than it is in finding solutions for the challenges of this new chapter in the history of humankind.

To my colleagues: Comrades, we are leading this Institution with a sense of pride and duty, and I know very well that we lead men and women, students who are determined to ensure that we all reach our destination safely and on time.

I said in one of our meetings that there are more enemies on our way, more than we can imagine. I think you witnessed that during the course of this week. The excitement and unnecessary confusions caused by some confused and loosed charlatans bear testimony to my statements. We should not reveal our game plans unless we are ready to slam.

Let me also borrow from the words of the late Albert Lethuli when he said and I quote: “There remains before us the building of the new land, from the ruins of the old narrow groups, a synthesis of the rich cultural strains which we have inherited. The task is immense”. Lastly, a navy divided within its ranks will be vanquished and destroyed by the enemy, but a navy united in purpose and action, loyalty and commitment will not drawn but sail on to victory.

In conclusion, let me call upon all political structures, church denominations, developmental structures, clubs, societies and forums to put aside all their differences, ideological insinuations and forge unity towards transforming Qwaqwa Campus of University of the Free State into an institution that is seen playing vigilant role in developing students academically, politically, socially, spiritually, religiously, culturally and otherwise.

Program Director, let me end my speech by indicating that every drop of my blood is telling me that Uniqwa is my home. I firstly became a student here, I became an activist here, I became a leader here, I became a president here, I will become a graduant here and hopefully I will become an employee here. So never, doubt my commitment towards the community of this campus.

Please be informed, in a central University of Technology’s way, that if there is no UNIQWA in HEAVEN, then I am not GOING.

Let us broaden the social base.

Tello Titus Wa-Motloung President General
