Media effectively used to save the giraffe
“If we can save the habitat wildlife need, then the animals will be just fine,” said Dr Francois Deacon, a wildlife habitat expert in the UFS Department of Animal, Wildlife and Grassland Sciences.

The University of the Free State (UFS) is leading the fight against the extinction of giraffes and has assembled the largest research team in the world to manage, coordinate, and address this issue. Seven UFS departments are involved in this research. 

Dr Francois Deacon, a wildlife habitat expert in the UFS Department of Animal, Wildlife and Grassland Sciences, is leading the team of researchers who tasked themselves with better understanding the giraffe, and in so doing, save the giraffe. He said: "One way to stop the plummeting numbers is to learn more about how giraffes use their habitat and how much area they need in order to survive."

Dr Deacon focuses on the spatial ecology of wild animals. His main research focus is to understand the ecological and biological factors that regulate giraffe in their natural habitat.

Documentaries save

He collaborated with a documentary film crew to release the second in a trilogy of documentaries regarding giraffes and their natural habitat. The first, Last of the Longnecks, focused on the fact that giraffes are becoming extinct. The second documentary, Catching Giants, which was released last year, includes footage on how a multi-specialist research group of over 30 people from 10 different countries worked together to collect information about these little-known animals.

Documentaries such as these, together with a recent insert in the local wildlife documentary on SABC 2, 50/50, also helped to raise awareness on the giraffe and its plight.

Telling the truth

Dr Deacon said: “It is extremely important for the public to see how involved we really are with a major problem such as a species becoming extinct. Media exposure outlines the truth of what man is doing to nature. Cooperating with media such as the BBC, National Geographic, and 50/50, offers other journalists, producers, editors, and authors the opportunity to also take responsibility for raising awareness on the issue.” 

“Apart from the fact that awareness is shedding light on the problem, it also highlights who the leaders in this field are, what they are doing to address the problem, and what more is needed to make a change. The latter includes the funding of postgraduate students to conduct further research on this matter. If we were able to gather sufficient knowledge through different research questions across the globe, we could really make a difference in saving giraffes from extinction.”

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!
