Give the same aerial imagery to two dozen geologists, ask them all to trace the active faults, and you might expect the answers to converge, especially the ones from decades-hardened professionals.…
Ask a hydrologist what a "hundred-year" downpour looks like for a given town, and the honest answer is that they are guessing from thin evidence. A rain gauge that has been running for thirty years…
For two decades, the story of Europe's air has been one of slow, hard-won improvement. Cleaner engines, tighter industrial rules, and the retreat of coal have pulled soot and sulphur down year after…
The plan for the Norwegian North Sea is to take carbon dioxide captured from industry, pipe it out under the seabed, and leave it there for good. Several storage licenses have already been awarded on…
On 23 November 1980, an earthquake struck the Irpinia district of southern Italy and did not stop at one fault. The rupture broke three fault segments in sequence, reaching magnitude 6.9 and killing…
Every step you take sends a small pulse of energy into the ground. It is far too weak to feel, and normally far too weak to bother with. But run a fibre-optic cable along the street and watch it…
A jet crossing the sound barrier does not gently speed up past its own noise. It compresses the pressure waves it is making into a single sharp front, and the boom arrives all at once. Some…
A volcano does not have to be quiet just because it is underwater. It bubbles, hisses, and occasionally coughs, and all of that makes sound. Sound travels well through water, better in many ways than…
Picture a weather model. Its job is not to label a picture but to take one continuous field (the temperature and pressure and wind across every point of the atmosphere at noon) and return another…
Ask a generative model trained on a database of known crystals to invent something new, and it faces a quiet contradiction. Everything in its training rewarded it for producing structures that look…
A hailstone measured 16 centimetres across when it fell over northern Italy in 2023, roughly the width of a dinner plate. Eight years earlier, an F4 tornado tore through Mira and Dolo near Venice, at…
In the Brazilian savanna a capuchin monkey climbs onto a flat block of stone with a palm nut in one hand. It sets the nut down, picks up a second stone, raises it above its head with both arms, and…
