After South Africa’s battle with the record-breaking drought of 2015, Prof Andries Jordaan from our Disaster Management Training and Education Centre for Africa(DiMTEC) saw room for improvement in dealing with this kind of disaster. 

Drought impact

Commercial farmers   who are usually net exporters of food crops   and communal farmers who own the bulk of the country’s livestock, were all hit hard in 2015. Most of the latter had no resources to spare as the drought progressed. The concern about the drought’s impact on the country’s food production and availability resulted in a joint goal of preventing food scarcity during future droughts.

Prof Jordaan’s visit to the National Drought Mitigation Center (NDMC) in Lincoln, Nebraska, in the US, several years ago prepared him to better equip communities in South Africa to deal with drought situations. “I recognised that in spite of the impact DiMTEC has been able to make on disaster preparedness, a gap remained in disaster response in South Africa.”

Sharing knowledge

In August this year Prof Jordaan again visited the NDMC. This time he requested a few key players in South Africa’s agriculture and disaster response communities to join him. With him were Janse Rabie, head of Natural Resources at AgriSA, a nonprofit organisation that functions as an interface between the government and about 28 000 South Africa farmers, and Moses Musiwale Khangale, director of Fire Services for the South African Ministry of Cooperative Governance and Traditional Affairs.

The South African delegation met with and learnt from climatologists, geospatial technologists, and outreach and planning analysts.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
