President Donald Trump appears to have ordered a return to nuclear testing after decades of uneasy but effective treaties banning the practice – but will it actually happen?

Computers built with analogue circuits promise huge speed and efficiency gains over ordinary computers, but normally at the cost of accuracy. Now, an analogue computer designed to carry out calculations that are key to AI training could fix that

Economists, bankers and even the boss of OpenAI are warning of a rapidly inflating AI bubble. If and when it bursts, what will happen to the technological breakthroughs of the past few years?

A new book and documentary from James Bluemel tells the story of the space race so far in photographs, a mix of images from astronauts' own collections and NASA archives

A memory chip just 10 atoms thick has been tested in a lab and integrated into conventional chips, demonstrating a technology that could improve the capacity of our devices

It was previously thought that children younger than 7 couldn't find efficient solutions to complex problems, but new research suggests that much earlier, children can happen upon known sorting algorithms used by computer scientists

The UK government has announced a raft of tiny nuclear power projects, while Russia, China and a host of tech giants are also betting big on small nuclear reactor designs. Does the idea make sense and can they really be built any time soon?

A rock found last year on the surface of Mars offered tantalising evidence that life once existed on the Red Planet. Now scientists have found yet more evidence that could point to the existence of ancient organisms – but we can't know for certain without returning samples to Earth

An exceptionally loud collision between two black holes has been detected by the LIGO gravitational wave observatory, enabling physicists to test a theorem postulated by Stephen Hawking in 1971

The planet TRAPPIST-1e lies in its star’s Goldilocks zone, where water remains liquid – and an analysis suggests it might have a nitrogen-rich atmosphere like Earth’s
