Nigeria isn’t big on 3D printing. Teaching students how to use it could change this

SCIENCE, TECH AND INNOVATION

3D printing is a technology that’s forecast to change the world. Already several fortune 500 companies – such as Siemens, General Electric, and Boeing – have invested in it. OSEZUA IBHADODE, Research Assistant, University of Waterloo AKII IBHADODE, Professor of Manufacturing, Federal University of Petroleum Resources, Effurun 3D printing mimics regular paper printing where a computer-aided designed part is sent to a printer for direct manufacture. Technically, this involves the digital data of a computer-aided 3D model design being sent to the printer which then produces the object layer-by-layer. The process enables the conversion of almost any virtual object into…

‘Spooky’ AI tool brings dead relatives’ photos to life

SCIENCE, TECH AND INNOVATION

UMBERTO BACCHI LIKE the animated paintings that adorn the walls of Harry Potter's school, a new online tool promises to bring portraits of dead relatives to life, stirring debate about the use of technology to impersonate people. Genealogy company MyHeritage launched its "Deep Nostalgia" feature earlier this week, allowing users to turn stills into short videos showing the person in the photograph smiling, winking and nodding. "Seeing our beloved ancestors' faces come to life ... lets us imagine how they might have been in reality, and provides a profound new way of connecting to our family history," MyHeritage founder Gilad…

Why South Africa’s electricity blackouts are set to continue for the next five years

SCIENCE, TECH AND INNOVATION

SOUTH Africa is once more experiencing periodic power cuts. These typically take the form of scheduled supply interruptions, for two to four hours a day, whenever the country’s electricity system is overloaded. Such overloading currently happens on 40-50 days a year. HARTMUT WINKLER, Professor of Physics, University of Johannesburg Eskom, the country’s power utility, recently admitted that such interruptions are likely to persist for as long as the next five years. This is because of the increased down-time of the rapidly ageing fleet of coal plants. But it is also due to delays in setting up new power plants. The…

Ghana’s electricity supply mix has improved, but reliability and cost is still a challenge

SCIENCE, TECH AND INNOVATION

GHANA has made significant progress over the past 10 years in increasing electricity generation and access. This has supported higher levels of economic growth. However, beneath these improvements lies inefficiencies, including extraordinarily high distribution losses. Electricity is also quite expensive in Ghana. If not addressed, these issues could derail Ghana’s development agenda. THEOPHILUS ACHEAMPONG, Associate lecturer, University of Aberdeen BRIDGET O. MENYEH, Research Associate, Loughborough University As countries transition their economies to ones that use less carbon, they need to build balanced energy systems. These must be anchored on high energy security, universal access at affordable prices and low emissions.…

Social media users in Kenya and South Africa trust science, but still share COVID-19 hoaxes

SCIENCE, TECH AND INNOVATION

THR COVID-19 pandemic has led to widespread disinformation circulating on social media globally. This includes false information about the virus, its origins and possible cures for the disease it causes. Much of the inaccurate information was related to China, the country where the first cases of atypical pneumonia were reported in December 2019. This was determined in January 2020 to be caused by a novel coronavirus. HERMAN WASSERMAN, Professor of Media Studies in the Centre for Film and Media Studies, University of Cape Town DANI MADRID-MORALES, Assistant Professor in Journalism at the Jack J. Valenti School of Communication, University of…

We found traces of drugs in a dam that supplies Nigeria’s capital city

SCIENCE, TECH AND INNOVATION

PHARMACEUTICALS – drugs used to prevent or treat human and animal diseases – are essential for health and well-being. But the increasing use of these drugs means that remnants of them are showing up in the aquatic environment. They are contaminating our waters. IFENNA ILECHUKWU, Lecturer of Environmental Chemistry, Madonna University, Nigeria Pharmaceuticals are part of a group of substances known as emerging contaminants. Although they are potentially harmful to human and ecological health, they are yet to be regulated and routinely monitored in the environment. Most conventional treatment plants typically do not remove emerging pollutants because they were not…

Dance off: Why are Black TikTok creators going on strike?

SCIENCE, TECH AND INNOVATION

SHARON KIMATHI BLACK dance creators are boycotting TikTok on the grounds that their viral routines are being co-opted by white social media influencers without credit or compensation. How did the strike start and what steps could the Chinese video app take to meet the demands of those protesting? How did we get here? TikTok is a social media app that hosts short musical clips ranging from three to 60 seconds where people lip-sync, perform skits, take on challenges and perform dance routines. Top-performing creatives use the app to gain followers and become ‘influencers’ which can lead to lucrative opportunities in…

Archaeology in West Africa could rewrite the textbooks on human evolution

SCIENCE, TECH AND INNOVATION

OUR species, Homo sapiens, rose in Africa some 300,000 years ago. The objects that early humans made and used, known as the Middle Stone Age material culture, are found throughout much of Africa and include a vast range of innovations. ELEANOR SCERRI, Independent Group Leader, Max Planck Institute for the Science of Human History Among them are bow and arrow technology, specialised tool forms, the long-distance transport of objects such as marine shells and obsidian, personal ornamentation, the use of pigments, water storage, and art. Although it is possible that other ancestors of modern humans contributed to this material culture…

An African woman in aerospace engineering

SCIENCE, TECH AND INNOVATION

MERCY WANGARE VENTURING into space, like the world of startups, is not for the faint-hearted. For aerospace engineer Wanjiku Chebet Kanjumba, however, space is a place for adventure, with unlimited possibilities. Having trained for space and even donned the full space garb, she is determined to make her mark in space exploration. Even if she doesn't make it all the way into space. “As a child growing up in Kenya I was always fascinated by space, planets and our solar system. So, in high school, I studied sciences and that’s how my journey began,” recalled aerospace engineer Wanjiku Kanjumba from…
