Cadmium zinc telluride (CZT) is one of those materials that sounds like a chemistry-class footnote — until you see what it enables. In the BBC’s reporting, CZT sits at the centre of a quiet shift in medical imaging and radiation detection: faster scans, lower doses, and more information captured per photon. The catch is that […]

A boat hull is the kind of object 3D printing has always promised to make cheaper: big, complex, labour-heavy, and usually slow to build. In the Dutch city of Delft, one team says it can now print a hull in days rather than weeks by combining a tailored plastic‑and‑fibreglass mix with a large-format printer that

For years, travel tech has been about reducing friction: fewer emails, fewer middlemen, fewer “can you send the bank details again?” moments between a traveller and the people actually delivering the experience. A BBC report on Nigerian entrepreneur Rory Okoli and her start-up TripZapp is a small snapshot of that bigger shift—using modern payment and

If you listen to the story Silicon Valley tells about AI, it sounds like a clean engineering arc: bigger models, better answers, more productivity. If you listen to what markets and governments are quietly worrying about, it sounds like something else entirely: concentration risk, energy constraints, and a capital cycle so large it could distort

Europe’s shadow-fleet standoff isn’t just a sanctions story. It’s a stress test for the rules that make global shipping work: flags, insurance, and who pays when something goes wrong. In the Baltic Sea, coastguards can talk to tankers and monitor them — but stopping them is legally and politically hard. What’s emerging, according to reporting

Electric bikes in Nairobi aren’t just a clean-tech curiosity. They’re a bet that the most expensive part of delivery — the “last mile” to a customer’s door — can be made cheaper, more reliable, and easier to scale in dense cities. In a short BBC video feature, a Kenyan start-up called eWaka Mobility is presented

Social platforms have always had spam and junk. What’s new is that generative AI has made “content production” almost free — and that changes the balance between what users want and what the feed can economically deliver. AI “slop” (cheap, low-effort synthetic images and videos) is not just an aesthetic complaint. It’s a signal that

Moltbook looks, at first glance, like “Reddit for bots”. That framing is catchy, but it hides the real story: it’s an early experiment in what happens when agentic AI systems are given a shared public space, identities, and lightweight social feedback (posts, replies, upvotes). If it works the way enthusiasts hope, it becomes an interoperability

China is moving to make sure you can always open an EV door the old-fashioned way: with a physical handle and a mechanical release. The new rules target “hidden” or flush door handles that look sleek but can be hard to find or fail when electronics or power systems are compromised. While the regulation applies

Elon Musk’s SpaceX says it is acquiring his AI company xAI, a move that effectively ties together three expensive pieces of the modern tech stack: model training, data-center-scale compute, and a global distribution network. The deal matters less as a corporate reshuffle and more as a bet on where AI bottlenecks will be in the
