The water in your cup of coffee is about 125 millilitres, but the water behind it is closer to 140 litres — nearly all of it associated with growing the beans long before anyone boiled a kettle
1+ hour, 1+ min ago (195+ words) Hold two numbers side by side. One is the small pour of dark liquid in front of you, a few gulps, gone in minutes. The other is a figure more than a thousand...
JWST found water-altered clay minerals on two of Neptune's tiny inner moons and its rings that probably formed deep inside much larger icy worlds — compelling evidence that today's moons may be rubble from Neptune's original satellite system, destroyed when the captured moon Triton tore through it billions of years ago.
2+ hour, 1+ min ago (332+ words) Webb found magnesium-rich phyllosilicates on Larissa, Galatea and Neptune’s rings, pointing to altered rock excavated from much larger ancient icy bodies....
AI data centres are being criticised for the water they use, but one kilogram of beef can require roughly 15,000 litres to produce — a staggering reminder that some of the biggest environmental costs are still sitting on our plates
3+ hour, 13+ min ago (23+ words) The outcry over AI's water consumption obscures a harder truth: our dinner plates have been quietly guzzling vastly more all along....
JWST spotted an object 660 million years after the Big Bang that looks like a star the size of our solar system but shines 100 billion times brighter than any star — and the only thing that could explain it is a black hole wrapped inside
3+ hour, 26+ min ago (29+ words) MoM-BH*-1 is a compact source at redshift 7.7569 whose extreme spectrum fits a black hole buried in dense gas, although the Solar System scale and luminosity are modelled....
RNA is supposed to fall apart within hours, yet researchers have now read it from a mammoth frozen in Siberian permafrost 39,000 years ago — and the transcripts caught his muscle tissue in the middle of a stress response
6+ hour, 10+ min ago (25+ words) RNA is the molecule biologists generally treat as disposable. Unlike DNA, which is built to be a stable long-term archive, RNA is manufactured, used, and...
A pop-up tag on a pregnant porbeagle shark kept reporting for four days after it stopped moving like a shark — rising and falling through the water at a constant 22°C, five degrees warmer than the sea, from inside whatever had swallowed it
8+ hour, 11+ min ago (23+ words) A shark's final days revealed an unexpected predator—and raised urgent questions about what hunts the ocean's apex carnivores....
Earth has a blue sky and red sunsets; Mars has a red sky and blue sunsets — and the reason for both is exactly the same mechanism, running in reverse because the dust is a different size
16+ hour, 13+ min ago (677+ words) Scattered dust particles reveal why two worlds see opposite skies—a physics lesson written in light and size.

Scientists led by UCLA found that permanently shaded parts of pits on the Moon stay near a constant 17°C while the exposed surface swings between 127°C and −173°C — meaning humanity's first permanent lunar address may be underground.
20+ hour, 56+ min ago (1377+ words) LRO thermal data and UCLA-led modelling show why permanent shade in certain lunar pits can remain near 17°C, while cave habitability still depends on access, structure, air and power.

Dolphins on opposite sides of Australia, thousands of kilometres apart, appear to have independently learned to chase fish into empty seashells and tip the trapped meal into their mouths — two populations, one remarkably similar invention.
14+ hour, 56+ min ago (1160+ words) The first published shelling records from eastern Australia suggest dolphins reinvented a rare tool-using tactic already known from Shark Bay, then began passing it on locally.

Starship's 33 engines push down with 74,400 kilonewtons at liftoff — roughly twice the force of the Saturn V that sent humans to the Moon, yet the whole vehicle is designed to be caught like a falling pencil and flown again the next day
1+ day, 15+ hour ago (1038+ words) SpaceX's bet is that catching and reusing a 5,000-tonne rocket is cheaper than building a new one, and the engineering challenges of making that work may matter far more than raw horsepower. Published August 16, 2026 · How we edit At the moment…...
