Storing CO₂ under the North Sea: how carbon storage projects work—and what critics worry about

Summary: Denmark’s Greensand Future project plans to inject large volumes of CO₂ into a depleted North Sea oilfield, turning old fossil infrastructure into a storage site for greenhouse gases. Supporters say carbon capture and storage (CCS) is necessary for “hard-to-abate” emissions. Critics warn it can be expensive, divert attention from cutting emissions directly, and create […]

‘Tech-dense’ farms: how sensors, software and AI are reshaping agriculture

Summary: Farms are becoming “tech dense”: fewer farms overall, but more technology per farm—sensors, precision spraying, satellite imagery, farm-management software, and AI-driven advice. Supporters say this boosts yields, reduces pesticide use, and helps farms survive climate volatility. Skeptics worry about cost, complexity, and whether the benefits accrue mainly to large operators. The reality is that

Smoke detectors are evolving: smart alarms, lithium-ion fires, and the false-alarm problem

Summary: Smoke detectors save lives, but modern homes and modern hazards are changing what “a fire” looks like—especially with lithium-ion battery incidents that can escalate extremely quickly. The industry is responding with smarter, connected alarms and new sensing approaches (including camera-based AI detection), while also trying to reduce false alarms that cause people to disable

Smaller data centres, closer to users: why ‘edge’ compute is back

Summary: While tech giants continue to build enormous “AI factory” data centres, a counter-trend is gaining attention: smaller data centres closer to users (“edge” compute), on-device AI, and even reusing waste heat for buildings. The argument is not that hyperscale data centres vanish overnight, but that the default architecture of computing may shift from “everything

Why more CEOs are sharing the top job: the case for (and against) co-CEOs

Summary: A small but growing number of companies are experimenting with co-CEO leadership structures—splitting the top job between two people. Supporters say it reduces hubris, shares the workload, and lets leaders specialise. Critics say it can create confusion, power struggles, and unclear accountability. This is not just a corporate curiosity. It reflects a world where

Why Excel won’t die: network effects, governance gaps, and the AI-era spreadsheet problem

Summary: Excel is 40 years old and still everywhere—even as organisations talk about modern data platforms and AI. The reason isn’t that Excel is “best practice.” It’s that Excel is a universal interface: flexible, teachable, and fast for small analyses. The danger is when spreadsheets quietly become production systems—undocumented macros, fragile workflows, and critical decisions

Liquid cooling is becoming the bottleneck tech for AI data centres

Summary: Data centres are running hotter as AI workloads push chips to higher power levels, and “just blow more air” is increasingly not enough. That’s why the industry is moving toward liquid cooling — from cold plates and microfluidic channels to full-on “showers” and immersion baths — to keep servers stable, cut energy used for

Fire-blocking materials are being reinvented — because the old flame retardants were toxic

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

Bakers vs robots is the wrong debate: why food automation is becoming hybrid by necessity

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
