Deepfakes and South African law: remedies on paper, gaps in practice

Deepfakes and South African law: remedies on paper, gaps in practice

DEEPFAKES are forgeries of people’s faces, voices and likeness generated through artificial intelligence (AI). They create a serious digital deception. Deepfakes undermine constitutional rights, reduce trust in media and distort fairness in elections. While many countries have laws that address the risks caused by deepfakes, enforcement remains a challenge. Deepfakes began to be widely created in 2017 after they’d first appeared on Reddit, a discussion website of forums where people exchange information. A Reddit user called Deepfakes shared an AI software tool that could superimpose celebrities’ faces on pornographic videos. AI-generated media became widely accessible through software apps that enable…

Hype and western values are shaping AI reporting in Africa: what needs to change

Hype and western values are shaping AI reporting in Africa: what needs to change

NEWS media shape public understanding of artificial intelligence (AI) and influence how society interacts with these technologies. For many people, especially those who have not sought more knowledge about AI elsewhere, media platforms are a primary source of information. This is particularly significant in Africa, where historical and socioeconomic contexts like colonial legacies and uneven technology transfer shape how AI is understood and adopted. Consequently, the way African news media represent and frame AI carries weight in shaping broader public discourse. To explore how African media report on AI, we, as media researchers, analysed 724 news articles about AI from…

Do elephants make deliberate gestures to ask for things? Our study says yes

Do elephants make deliberate gestures to ask for things? Our study says yes

ELEPHANTS are known for their intelligence, strong social bonds, and good memories. But do they communicate to show real intention? A new study suggests they do. The research showed that elephants gestured to ask for food when a person was around and that they kept gesturing when they didn’t receive all the food. These are signs that the elephants are trying to communicate with intention. We spoke to lead author Vesta Eleuteri, a PhD candidate, to learn more about what this means and why it matters. Why did you study how elephants use gestures to communicate? Most of the research…

Africa’s innovations are overlooked because global measures don’t fit: what needs to change

Africa’s innovations are overlooked because global measures don’t fit: what needs to change

AFRICAN governments and development agencies have embraced science, technology and innovation as levers for development over the past two decades. Science, technology and innovation boost productivity, cut transaction costs, open new business opportunities and promote social inclusion. They also help societies tackle grand challenges such as climate change and persistent poverty. By 2020, at least 25 African countries had a national policy framework for science, technology and innovation. This compares with only about 8 in 2010. Science, technology and innovation measurements are essential because they allow policymakers to see whether investments are yielding results. Without adequate metrics, scarce resources can…

Fossils show colonies of reptiles lived communally 250 million years ago: new South African study

Fossils show colonies of reptiles lived communally 250 million years ago: new South African study

A fossilised colony of small burrowing reptiles that lived some 250 million years ago was recently found in South Africa. It’s the first time that the Procolophon trigoniceps, which lived in the lowlands of what was then the ancient supercontinent of Gondwana (today the central Karoo), has been found to have lived and died communally in complex, underground burrows. Up till now, they have only been found as single specimens. With a short neck, long body and long tail, the Procolophon trigoniceps was about half a metre long, roughly the same size as a juvenile monitor lizard. It had a…

Which African countries are flourishing? Scientists have a new way of measuring well-being

Which African countries are flourishing? Scientists have a new way of measuring well-being

WHAT does it mean to live a good life? Psychologists and social scientists have been focusing on a new idea called flourishing – a sense of well-being that goes beyond just happiness or success. It’s about your whole life being good, including how you interact with other people and your community. So then, how do Africans fare when it comes to flourishing? Victor Counted is a psychological scientist whose research across 40 African countries offers a data-rich rethinking of flourishing on the continent. His findings challenge the dominant narrative that Africa is “lagging behind” in development by showing a more…

Fruit peels could help power your smartphone’s camera flash – here’s how

Fruit peels could help power your smartphone’s camera flash – here’s how

IMAGINE turning fruit waste into technology that stores electricity. This would reduce food waste and promote clean energy storage. Postdoctoral researcher Vianney Ngoyi Kitenge transformed mangosteen peels into specialised carbon materials that he used to make supercapacitor energy storage cells. He came up with a simplified way to do this, hugely reducing the cost. This breakthrough converts agricultural waste into valuable components for energy storage technology. He sets out how it works and what’s needed to make it happen. What is a supercapacitor? Supercapacitors are a type of energy storage cell, similar to a battery, but with some key differences.…

AI-driven motion capture is transforming sports and exercise science

AI-driven motion capture is transforming sports and exercise science

IN sport, the margin between success and failure is often measured in milliseconds. It could be a cricketer adjusting their foot positioning, a runner refining their sprint start or a footballer perfecting their passing. This is where motion capture comes in – among the many approaches being used for athletic performance and movement analysis. Conventional motion capture tracks a person’s movements by using sensors or reflective markers linked to cameras. This provides data that helps sports scientists analyse how to improve an athlete’s performance, personalise their training programme and prevent possible injury. But for decades, motion capture in sport has…

Light is the science of the future – the Africans using it to solve local challenges

Light is the science of the future – the Africans using it to solve local challenges

LIGHT is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fibre optic networks. The smartphone is a great example of the power of light. Inside the box, its electronic functionality works because of quantum mechanics. The front screen is an entirely photonic device: liquid crystals controlling light. The back, too, has white light-emitting diodes for a flash, and lenses to capture images. We use the word photonics, and sometimes…

How do coconuts get their water?

How do coconuts get their water?

COCONUT trees are iconic plants found across the world’s tropical regions. They’re called “nature’s supermarket” or the “tree of life” in several cultures because every part of the coconut tree is used. Its leaves can be used to thatch homes, its heart can be eaten and its roots have medicinal uses. The refreshing liquid found within a young green coconut is a highly prized component of the coconut palm. Coconuts are unique in the world of fruits because they have a large internal cavity filled with water. Other fruits typically store water within individual cells or pulp. I’m a food…
