Anthropic's AI tool has beaten GPT-4 in key metrics and has a few surprises up its sleeve — including pontificating about its existence and realizing when it was being tested.
"Exceptionally preserved" fossils of an ancient shark that lived alongside the dinosaurs has finally revealed what the predator looked like — and why it may have gone extinct.
Bioluminescence traces back to the Cambrian era — 540 million years ago — and could have been used for communication, courtship and camouflage among the earliest ocean creatures.
An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.
In the early hours of Tuesday (April 23), quadruple solar flares near-simultaneously exploded from across the sun's surface, and there's a good chance that one of these outbursts launched a solar storm toward Earth.
On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's…
NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.
The near-Earth asteroid Kamo'oalewa, which orbits alongside our planet as a 'minimoon,' may have originated from Giordano Bruno crater on the far side of the moon, new research suggests.
A giant-hail event that hit Girona in northwest Spain in 2022 was fueled by climate change, with a marine heatwave helping to intensify the storm that killed a small child.
China's experimental moon satellites Tiandu-1 and 2 are testing lunar communications and navigation tech. Recently, they shared this image of the lunar surface with a ghostly Earth in the background.
In 1898, the crew of the first scientific expedition to Antarctica became trapped inside sea ice around the southernmost continent. Much of that once thick ice is dwindling, says polar researcher Edward Doddridge.
JWST's surprise discovery of methane emissions and likely aurorae over a distant brown dwarf could indicate this "failed star" is orbited by an active moon.
A new system uses generative AI to predict weather faster and more cheaply than ever — while detecting difficult-to-spot extreme weather events — beating the world's major weather agencies.
Researchers suggest that the famed Golconda diamonds, including the Hope Diamond and Koh-i-noor, may have originated from a volcanic outcrop nearly 200 miles from where they were mined.
Imagine the sound of a dog walking across a tile floor, the "click, click, click" of its claws tapping against the ground. Now, imagine a cat padding across the same floor — the difference is the cat moves in total silence. Cats can fully…
