Built for two years, it ran for twenty-two: NASA has switched off Swift, and the archive it leaves is the point
Swift’s trick was speed: it swung its own cameras onto a burst in seconds and told every other telescope where to look. Its data will…

Two mathematicians kept their drafts in OpenAI’s own coding tool, then OpenAI announced it had solved the problem — and the row is really about who can still be trusted to check science
The dispute will probably never be resolved. What it exposes is a journal system already failing to keep AI-written material out, and no…

The Amazon has lost 240 million acres of primary forest — the size of Texas and California together
Fifteen per cent of the Amazon’s primary forest is permanently gone. The researchers say the real story is not a looming tipping point but…

Astronomers say they have found the exact dawn Van Gogh painted in The Starry Night — and the museum disagrees
The moon above Venus, with the Hyades cluster nearby, occurs on only three dawns in the summer of 1889. One of them is a very good match…

Physicists say the smallest black holes could leak gravity into a fifth dimension, which would make them the only instrument we have for detecting one
A Physical Review D paper from Lehman College argues tiny black holes formed just after the Big Bang are dense enough for their gravity to…

A fossil dug up in Japan 30 years ago turns out to be a new armoured dinosaur that walked from America
CT scans of a skull found in Hokkaido in 1995 identified Nipponopelta ezoensis, a nodosaurid between 93 and 100 million years old — and…

Bacteria survived a laboratory copy of Enceladus — the ocean under Saturn’s moon may be habitable
Researchers in Berlin rebuilt the conditions of the ocean beneath Enceladus in a lab and put deep-sea vent bacteria into it. They lived on…
