The COVID-19 pandemic has disrupted the entire world, claiming more than two million lives and sparing no region. The world is confronted with urgent unsolved challenges, with the poor and vulnerable populations, low-skilled workers, and refugees most affected. 

These challenges will be addressed by the Lancet COVID-19 Commission and its various task forces, one of which is the Fiscal Policy and Financial Markets task force. Prof Philippe Burger, Professor of Economics and Pro-Vice-Chancellor: Poverty, Inequality and Economic Development at the University of the Free State, serves as a member of the commission’s Fiscal Policy and Financial Markets task force. The eleven members of the task force include two Nobel prize laureates in economics, as well as academics and public-policy specialists from across the world, under the co-chairpersonship of Dr Vitor Gaspar (Director of the Department of Fiscal Affairs at the IMF) and Prof Felipe Larraín (Professor of Economics, Pontifical Catholic University of Chile and former Minister of Finance of Chile).

The commission is an interdisciplinary initiative across the health sciences, business, finance, and public policy, and was created to help speed up global, equitable, and lasting solutions to the pandemic. The work of the commission is divided into 12 task forces, each composed of members from diverse disciplinary interests, geographies, and identities. These task forces provide support in areas ranging from vaccine development to humanitarian relief strategies, to safe workplaces, to global economic recovery. 

Key aims of the commission is to speed up awareness and the worldwide adoption of strategies to suppress transmission, as well as to ensure that COVID-19 vaccines and key technologies are equitably accessible across the world.

The Fiscal Policy and Financial Markets task force will consider fiscal and financial issues related to the pandemic affecting advanced, emerging market, and developing economies. Based on evidence and best practices, the task force will provide recommendations on managing the effects of the pandemic and will also manage the transition to a resilient, smart, inclusive, and green growth path. Issues related to fiscal sustainability as well as debt relief in poor countries are on the task team’s agenda.

Many multilateral institutions such as the WHO, the IMF, the World Bank, the Food and Agricultural Organisation of the UN, the UN World Food Programme, the UN Educational, Scientific and Cultural Organisation, the Organisation for Economic Co-operation and Development, and others face profound challenges in undertaking their crucial missions to coordinate the global response to the pandemic. The Lancet COVID-19 Commission also aims to make recommendations to strengthen the efficacy of these critical institutions. Moreover, the commission reaches out to regional groupings, including the African Union, the Association of Southeast Asian Nations (ASEAN), the Southern Common Market (MERCOSUR), and others, to support the efforts of these bodies in fighting the pandemic. 

The Lancet COVID-19 Commission and its task teams include leaders in health science and healthcare delivery, business, politics, and finance from across the world. They volunteer to serve in their individual capacities – not as formal representatives of their home institutions – and will work together towards a shared and comprehensive outlook on how to stop the pandemic and how best to promote an equitable and sustainable recovery.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
