4IR Prof Marwala

A computer programmed to play poker and learning by itself how to bluff; an algorithm that predicts whether two countries will ever go to war; machines that detect epilepsy with almost flawless accuracy these are some of the groundbreaking abilities brought about by technologies associated with the Fourth Industrial Revolution (4IR).

Addressing the first UFS public event to enhance 4IR awareness, Professor Tshilidzi Marwala, Vice-Chancellor and Principal of the University of Johannesburg, briefed staff, interested parties and members of the media about recent 4IR developments and their implications.

Prof Marwala is currently a thought leader on the impact of the 4IR on higher education in South Africa as well as the Deputy Chairperson of the national commission appointed by the president to formulate 4IR strategies for South Africa.

Industrial revolution history

He recapped how, during the first industrial revolution, people started to understand how nature worked, ultimately leading to the development of the steam engine.
The second industrial revolution was marked by the development of electromagnetism which led to electrification and mass production, while the third produced computerisation and a rise in digital technology. 

The fourth industrial revolution is characterised by a fusion of technologies that blur the lines between cyber, physical and biological systems. This has led to rapid advances in fields such as artificial intelligence, quantum computing and 3D printing.


Artificial intelligence

Prof Marwala pointed out that, although fears were rife of machines taking over people’s jobs, the flipside of the coin was that dangerous jobs such as fire rescue operations could be carried out by machines without endangering lives.

Artificial intelligence can be employed to prevent bridge and building collapses by monitoring the condition of structures. It can also be used in credit scoring, where machines search for and analyse all the available data on a credit applicant, without having to rely only on the (sometimes fraudulent) information supplied by the credit seeker. 

He emphasised the great need to develop algorithms applicable to our continent, such as translating software that makes provision for the clicks in languages like isiXhosa, and facial recognition software that incorporates data collected in African countries. 


Is Africa ready? 

Responding to a question from an audience member, Prof Marwala indicated that Africa was certainly not ready for the 4IR when it came to the content of teaching curricula and infrastructure.

“As universities, we should not sit back and wait for change. We have the responsibility to lead our societies to have the same experiences as elsewhere in the world,” he concluded.

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!
