One of the strongest signs of life outside Earth was announced by astronomers this week, but other astronomers were quick to caution how difficult verifying such a detection can be. That raises the question: will there ever come a point where we can definitively say we have evidence of extraterrestrial life, and when might that be? The supposed signs of life were picked up by the James Webb Space Telescope (JWST), from the exoplanet K2-18b, 124 light years away.

The Antikythera mechanism, a mysterious ancient Greek device that is often called the world’s first computer, may not have functioned at all, according to a simulation of its workings. But researchers say we can’t be sure of this since the machine is so badly damaged. Since the mechanism was discovered in 1901, in a shipwreck thought to date to around 60 BC, researchers have struggled to work out exactly why it was built.

People can no longer reliably tell AI and human voices apart, except in examples of conversational-style speech or with familiar voices, such as those of friends or family. Spoofing human voices using artificial intelligence has long been a research goal, but until recently, people have mostly been able to recognise an AI-generated voice. In 2023, researchers found that English and Mandarin speakers could differentiate between real and deepfake voices about 70 per cent of the time.

The asteroid Bennu, which NASA brought back samples from to Earth in 2023, is baffling scientists with its abundance of nitrogen and odd magnetic properties. https://t.co/tDkB8geBg6
A computer contained in a thin thread of stitchable fabric could be used to record, and understand, all sorts of information about the body that devices like Apple watches can't. And it's being tested on Canadian and US soldiers right now, in the Arctic. https://t.co/HOeJ3T4OE9
50 years after it was first dreamt up by Douglas Hofstadter, this fascinating fractal butterfly has been found in a real physical system (in graphene, no less)! It's butterflies all the way down 🦋 https://t.co/dRfxIQ3yDg
