The Woman King is a big-budget Hollywood movie that has been anticipated since 2018, when US star Viola Davis was announced as the lead in the story of the “amazons” of Dahomey.

The “amazons” were exceptionally skilful women…
The Research Brief is a short take about interesting academic work. The big idea People appear to be more willing to lie for personal gain when they use a laptop versus a smartphone, our new peer-reviewed research shows. Given that the two devices have nearly identical technical capabilities – they’re both boxes with electronic brains – this surprised us and highlights the psychological impact of technology. Our first in a planned series of studies was a version of what economists call the ultimatum game. In the take-it-or-leave-it exercise, one player is told they’ll receive a certain sum of money, some…
US president Joe Biden’s invitation to South Africa’s President Cyril Ramaphosa to meet at the White House, and the latter’s acceptance, are positive signs of renewed cooperation. But they do not suggest a return to the 1990s era of heady optimism between the two countries. These two diverse democracies are currently too divided domestically, amid new and escalating tensions globally that affect Africa. These negatives, however, add weight to the importance of the Biden-Ramaphosa meeting in Washington on 16 September 2022. There are four reasons for its political significance. Two speak to the two countries having a common agenda: both…

Such an adversary can be a nation state, a corporate entity or a private individual. The authoritative international Cybercrime Magazine expects global cybercrime costs to grow by 15% a year over the next five years, reaching $10.5 trillion…
Amid the continuous noise about cryptocurrencies, it’s often hard to pick out what really matters. However this month, if all goes to plan, the energy-hungry digital sector will undergo its biggest shake-up in years. Ethereum, the world’s second largest cryptocurrency, is tomorrow expected to start a technology changeover which, once complete, should cause its carbon emissions to plummet by 99%. The rapid growth in cryptocurrencies in recent years has been staggering. Unfortunately, so too has been their contribution to climate change, due to the enormous amount of electricity used by computers that manage the buying and selling of crypto coins.…

A professional, efficient and effective public service is key to a government’s ability to deliver on its mandate. That’s why South Africa’s constitution requires that the public service be institutionalised as a profession. Appointments must be based on merit and public servants are supposed to be honest, neutral and fair. Such a public service is a distinctive feature of modern democracy. It means the government bureaucracy is not tied to an incumbent political party. It remains in place no matter which party is in power, and is non-partisan. Administration can continue when political power changes hands. A professional public service…
Globally, men are twice as likely as women to start a business. Most research into how to start a business has been focused on men. Not much has looked at why women are not fully represented among entrepreneurs or how to change this. Yet it’s known that women entrepreneurs play an important role as leaders of entrepreneurial teams who contribute to economic growth and poverty reduction. Research shows that women in South Africa are less likely to consider starting a business than men. They are also significantly less likely to act on their entrepreneurial intentions. One reason could be the…

Not content with following every move you make on its apps, Meta has reportedly devised a way to also know everything you do in external websites accessed through its apps. Why is it going to such lengths? And is there a way to avoid this surveillance? ‘Injecting’ code to follow you Meta has a custom in-app browser that operates on Facebook, Instagram and any website you…
