According to the international market and consumer data company Statista’s June 2022 data, more than 4,6 billion people worldwide are using social media; this is an increase of 1 billion people compared to the total users in 2020. 

Delivering his lecture on ‘Social Media, Freedom of Expression, and the Law’ on the University of the Free State Bloemfontein Campus on 30 May 2022, John Jeffery, Deputy Minister of Justice and Constitutional Development, said, “The power of social media lies in the sheer magnitude of the number of people using it.”

He said: “Section 16 of the South African Constitution provides that everyone has the right to freedom of expression, which includes freedom of the press and other media; freedom to receive or impart information or ideas; freedom of artistic creativity; and academic freedom and freedom of scientific research.”

He advised perpetrators of malicious social media posts about the consequences and the harm to persons who are victims.

Depending on the circumstances, a person who suffers harm because of being the subject of someone else’s social media posts, can be protected under the Protection from Harassment Act. According to the Act, this is due to mental, psychological, physical, or economic harm.

Speaking at the Odeion School of Music, Deputy Minister Jeffery said, “Social media brings with it the importance of responsible use. As a social media user, you are entirely responsible for whatever appears on your social media accounts.’

He said: “Whatever you do in life – your conduct and your words – can be put onto various platforms and they will be there for a very long time. Do better, be better – and use social media to inspire people, to have an impact on the world, and to make it a better place.”

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!
