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 […]

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

Retailers are increasingly turning to “smart” surveillance to deal with a very old problem: theft. The newest wave goes beyond standard CCTV, using tools that can flag faces, bodies, or behaviour patterns in real time. A BBC report filmed by Jim Connolly shows how quickly this kind of AI-driven anti-shoplifting tech is moving from big

Crypto theft has a special kind of cruelty built into it. Even when your coins are gone, you can often still see them moving — hop by hop — across the public blockchain. It’s like watching your wallet being carried away through a glass corridor you’re not allowed to enter. A BBC investigation into crypto

Valve is heading towards a major UK courtroom fight over how much PC gamers pay on Steam — and, more importantly, why they pay it. A £656m collective legal action has been cleared to proceed, accusing the company of using its dominant position to keep prices higher than they should be and to “lock in”

Data breaches have become so routine that many people treat them like background noise — an annoying email, a password reset, then back to life. But the real danger often arrives later, when leaked details are stitched together into targeted attacks that feel personal, plausible, and hard to stop. A BBC investigation into scam victims

The UK’s advertising watchdog has once again drawn a bright line around cryptocurrency marketing — not by banning crypto itself, but by policing the story an ad tells. In a decision against Coinbase, the Advertising Standards Authority (ASA) said the campaign crossed a boundary by implying crypto could ease people’s cost-of-living concerns, while downplaying the

Heat pumps have become a symbol of home decarbonisation — the box that replaces a gas boiler. But the bigger climate lever is not one house at a time. It’s heat at city scale: networks of pipes that deliver hot water to thousands of buildings, fed by industrial-scale heat pumps that pull energy from rivers,

A lot of “automation stories” get told like a simple battle: machines versus people. But in food manufacturing — especially anything involving sticky caramel, fragile dough, hygiene rules, and brand nostalgia — the real question is different: Where does automation create value without destroying the product’s identity? The BBC’s reporting on biscuit and bread production

Most people think “fire safety” means alarms, sprinklers, and evacuation routes. But there’s a quieter layer underneath: the chemistry of the materials inside a building — whether a surface flashes, smoulders, drips, or forms a protective char. A new wave of flame-retardant technologies is emerging because the old answer (many 20th‑century retardants) came with an
