As we approach the end of another year, many people take this time to reflect on the successes they have achieved, as well as to appreciate their resilience in overcoming life's challenges. For some, this season of reflection serves as an opportunity to reward themselves for their accomplishments. However, for many others, the festivities become a coping mechanism, masking deeper pain and unresolved trauma.

This year has been marked by several successes, including the simple fact that we are still alive, despite the staggering number of lives lost in the country, but more so, in conflict zones. Countries like Sudan, South Sudan, the Democratic Republic of Congo (DRC), Mozambique, Palestine, and Ukraine have endured severe violence, with countless innocent lives taken. In these instances, the human cost continues to mount, making survival a powerful testament to resilience and divine grace in the face of such overwhelming adversity. Life itself is an accomplishment, but for countless individuals, it also carries untold stories of sorrow, stories not just from this year but from previous years as well. Families continue to grieve the loss of loved ones to the COVID-19 pandemic, and many have lost their livelihoods due to the economic downturn that followed. The situation is further exacerbated by South Africa’s unemployment rate, which exceeds 40% (expanded definition), making it increasingly difficult for many individuals to secure new sources of income.

The violence

In addition, South Africa continues to grapple with violence. Families mourn the loss of loved ones to murder — a pain that never truly heals, though families learn to live with it. The country’s murder rate remains alarmingly high, with slight fluctuations in the past five years looking only at the months of April to June across the years. In 2020, COVID-19 restrictions temporarily reduced murders to 3 466, but once the lockdown lifted, the rate surged to 5 760 in 2021, continuing to rise to 6 424 in 2022. Though slightly declining in 2023 and 2024, the numbers are still far too high. This reflects an ongoing crisis that demands stronger interventions, law enforcement, and efforts to address the socio-economic disparities that fuel crime.

Further compounding the year’s challenges, 2024 saw tragic events such as children dying from poisoned food, mass killings in the Eastern Cape, a rise in extortion, and an alarming increase in teenage pregnancies, especially in underprivileged communities. As we close the year, these issues do not vanish. In fact, they may intensify, often hidden beneath the veneer of holiday festivities.

The impact of alcohol

For many, these festivities are synonymous with alcohol consumption. Despite the economic struggles faced by many, a budget for alcohol remains a priority. This may seem counterintuitive, but it highlights the reality of people using alcohol to escape their suffering. Alcohol, like many other substances, becomes a coping mechanism for the trauma that so many endure.

In its 54th conference, the ANC rightly observed a universal phenomenon of alcohol abuse where socially and economically unequal societies tend to have higher levels of substance abuse, particularly alcohol and drugs. The §National Drug Master Plan 2019/24 identifies alcohol as the primary substance abused across racial and class lines in South Africa, largely due to its easy accessibility, affordability, and cultural associations. South Africa ranks among the high alcohol-consuming countries, with an average of 9.3 litres per capita annually, far surpassing the global average of 6.4 litres.

The consumption of alcohol is particularly concerning among young people, who often gain access to alcohol earlier than legally permitted, especially during the festive season. When young people normalise alcohol consumption, it often leads to lifelong addiction, impaired development, and an inability to fully participate in society. Tragically, in some cases, it results in fatal outcomes.

For the broader population, alcohol is often a catalyst for violence, both in public spaces and within homes. It exacerbates gender-based violence (GBV), fuels broken families, perpetuates cycles of poverty and substance abuse, and undermines social cohesion. These issues have plagued South Africa for years, with little success in addressing them.

The festive season is also associated with a rise in road accidents and fatalities, often linked to alcohol consumption. While this is only the tip of the iceberg, it reflects the broader societal damage caused by alcohol. Yet, alcohol continues to be marketed as a symbol of success, sophistication, and enjoyment. While alcohol-facilitated festivities and social gatherings in general may offer fleeting escapism, they ultimately fail to address the profound psychological and emotional wounds that individuals carry. Beneath the veneer of revelry and glamour, these events often leave participants with unhealed scars, merely postponing the inevitable pursuit of the next escapism opportunity. In truth, the industry exploits vulnerable individuals for profit, often masking the harm it inflicts on communities.

Despite the alcohol industry's substantial contribution to South Africa's GDP, a comprehensive cost-benefit analysis reveals that the industry's socioeconomic costs, encompassing both direct and indirect expenditures, as well as intangible externalities, significantly exceed its economic benefits. In the past, studies have shown that alcohol-related harm costs between 10% and 12% of the country’s GDP, while the benefits, including taxes and employment, account for a less than 10%. This disparity calls for a re-evaluation of the country’s relationship with alcohol. It’s a substance that not only fuels violence and the resulting trauma but also undermines the nation’s aspirations for a more prosperous and equitable future for all. We must question whether alcohol is truly indispensable. Does its social, cultural, or economic significance justify the considerable harm it causes to human life?

16 Days campaign

This truly is the time for the country to reconsider its approach to alcohol regulation. There have been ongoing debates about tightening restrictions on alcohol advertising, with proponents arguing that these measures could mitigate the damage caused by the industry. Some have also called for raising the legal drinking age, suggesting that delaying access to alcohol could benefit both individuals and the economy. Additionally, increasing excise duties could make alcohol less accessible, reducing its harmful impact on society. These steps require leaders who prioritise the lives of the people they serve over the profit margins of corporations. Ultimately, this serves as a clarion call to collective action, urging all stakeholders in society including families, faith-based organisations, community groups, educational institutions, and beyond, to assume a shared responsibility for reversing this destructive trend. By doing so, we can break the cycle of harm, mitigate the pervasive psychological and emotional trauma that permeates our society. Afterall, Life should be treated as sacred and worthy of protection and improvement at every opportunity.

In light of all these issues, we are also reminded of the 16 Days of Activism for No Violence against Women and Children Campaign, a global campaign aimed at raising awareness about violence against women and girls. Let this not be a mere rhetorical exercise, but a call to action, one that demands meaningful decisions and interventions to protect vulnerable individuals and build a society free of violence and harm.

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.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
