Scientists develop security check system that uses your breath

Biometric authentication could soon be revolutionized as scientists in Japan have developed a security tool which identifies people by their breath. Being able to fully rely on identity check systems is more crucial than ever for public institutions such as airports but also a wide variety of private companies. Researchers from Kyushu University said their olfactory sensor had an accuracy of 97 percent in a first series of tests. Chaiyanut Jirayupat from Kyushu University's Institute for Materials Chemistry and Engineering is the first author of the study. Speaking about the potential advantages compared to security checks of fingerprints, voices or…

WhatsApp adds new privacy controls for profile photos and ‘Last Seen’ status

After previewing the feature in beta last April, WhatsApp is rolling out greater privacy controls for Profile Photo, About, Status and Last Seen settings, the company tweeted. Until now, you could only block those settings for Everyone, My Contacts or Nobody, but the new update introduces a "My Contacts Except" option that offers far more granular control. The "Last Seen" status is a particular privacy danger, as it indicates when someone last checked the app. That provides a way to find out if a contact may have potentially seen your message even if they have read receipts turned off. The…

How many bones are in your body and why does the number change? We found the answers

Everyone has bones, no matter who you are or where you are, but not everyone understands the importance of changes in what’s going on inside their bodies.

The world's first carbon dioxide battery is here and needs only steel and water

The island of Sardinia in Italy is known as a world-famous tourist destination. It will now also be known as the home of the world's first carbon-dioxide battery launched by a startup, Energy Dome, Electrek reported. The role of carbon dioxide in heating up the planet is well acknowledged. While countries are making efforts to curb their carbon emissions, there is also the need to trap carbon dioxide that is currently being released to ensure that the planet's temperature increases remain under control. To achieve this, many are looking to capture carbon directly from the atmosphere and store it. However,…

Vietnam develops 'world's first' African swine fever vaccine for commercial use

Vietnam said on Wednesday it had successfully developed a vaccine to administer to pigs to fight African swine fever, with the aim of becoming the first country to commercially produce and export it.

It originated in Africa before spreading to Europe and Asia and has killed hundreds of millions of pigs globally. African swine fever is harmless to humans. "This is a milestone of the veterinary industry," deputy…

Russia launches new generation of laser weapons in Ukraine

Russia on Wednesday said it was using a new generation of powerful laser weapons in Ukraine to burn up drones, deploying some of Moscow’s secret weapons to counter a flood of Western arms supplied to its former Soviet neighbour.

Little is known about the specifics of the new laser weapons. Putin mentioned one called Peresvet, named after a medieval Orthodox warrior monk Alexander Peresvet who perished in mortal combat. Yury Borisov, the…

University drop-out builds electric mini-buses in Nigeria’s first

A 30-year old University drop-out Mustapha Gajibo has been converting petrol mini-buses into electric vehicles at his workshop, but he is now going a step further to build solar battery-powered buses from scratch in a push to promote clean energy and curb pollution. Africa's top producer and exporter of crude oil has heavily-subsidised gasoline and a patchy supply of electricity -- a combination that might discourage anyone from investing in electric vehicles. But the entrepreneur who is a resident of Maiduguri city in Nigeria's northeast, is undaunted. He says rising global oil prices and pollution make electric vehicles a worthwhile…

Looty seeks to digitally reclaim artworks looted from Africa by colonial powers

What if Africans somehow managed to access museums across the Western world, gather all the artwork looted from their territories during the colonial era, and take them back home? A young Nigerian man is attempting to do just that. But rather than physically breaking into museums and carting away the works of art, he wants to repatriate them digitally. "This is the first digital repatriation of stolen artwork," said 34-year-old Chidi, a Nigerian creative designer and founder of Looty, who declined to give his surname because, he said, he wants people to focus on his project and not his person.…

He was 5'7". After surgery, he’ll be 5'10"

When I first met Scott — not his real name — in early March, he was gently pushing a walker ahead of him. I had gotten lost trying to find the door to his apartment, so he had to come find me. Leaning against the door frame in a fitted T-shirt and shorts, he waved me over and then steadied himself. On a picture-perfect Los Angeles day like this one, had the circumstances been different, we probably would have met outside and enjoyed the sunshine. But he’s still getting used to his new legs. A few weeks earlier, Scott had…

Google’s undersea internet cable lands in Lagos, promises to create 1.6m jobs in 3 years

Google Africa has announced the arrival of its Equiano submarine cable in Lagos, Nigeria, the second city in Africa.

Russia tests nuclear-capable missile that Putin says will give enemies ‘food for thought’

Russia said Wednesday it had successfully conducted the first test launch of its new intercontinental ballistic missile as Russian President Vladimir Putin said it would give countries that "threaten" Moscow something to think about. Appearing on Russian television, Putin boasted that the missile, which has been under development for years, is capable of overcoming Western anti-missile defense systems. "This truly unique weapon will strengthen the combat potential of our armed forces, reliably ensure Russia's security from external threats and provide food for thought for those who, in the heat of frenzied aggressive rhetoric, try to threaten our country," Putin said,…

How this App is transforming education in Nigeria

Boye Oshinaga, Founder and CEO of Gradely, believes that now is a perfect time to start your own business in Africa. “There’s so much in just starting. You don’t know your journey, it may be two months like mine to build the minimum viable product – or it could be two years – but it doesn’t matter.” “We are playing the global landscape now so there are no local champions. Africa’s products can compete globally,” he adds. The genesis of his business idea came when he was visiting a school. He overheard a parent complaining about her child failing twice…
