Nearly imperceptible quantum flickers used to limit how precisely we could detect the way space-time ripples, but squeezing the laser light used in detectors overcomes this and doubles the number of gravitational waves we can see

Genetic analysis shows that microbes growing inside the International Space Station have adaptations for radiation and low gravity, and may pose a threat to astronauts

Medically evacuating an astronaut from space is difficult and expensive, and a new model predicts that one in three long-duration moon missions may require it

A distant planet should have been consumed when its star expanded to become a red giant, perhaps offering insights into planetary migration

A computer simulation suggests that some collisions between exotic, hypothetical stars would make space-time ripple with detectable waves

The first 18 satellites of a planned Chinese mega constellation are brighter than all but 500 stars in the sky, raising fears of a huge impact on astronomy

A detector on the International Space Station found signatures of unexpectedly abundant antimatter – which may have been created in clashes of dark matter particles

The European Space Agency's Hera spacecraft must be thoroughly tested before being sent to investigate the aftermath of the collision of NASA's DART probe with Dimorphos

My first sight of Saturn through a telescope inspired my love of space. Dig out your telescopes or visit your local astronomy club, and you may be lucky enough to spot our sixth planet's stunning thick band of rings, says Leah Crane

The Euclid space telescope's massive “cosmic atlas” promises to shed light on fundamental questions in physics and cosmology

General relativity teaches us that observing a black hole is all a question of perspective – and technique, says Chanda Prescod-Weinstein

Moin Hussain's debut feature film Sky Peals sees a man discover his father may be from outer space. Part sci-fi, part family drama, part coming-of-age tale, it is odd and otherworldly

The largest and most ambitious Martian drone yet could carry kilograms of scientific equipment over great distances and set itself down on the Red Planet unassisted

Averting an asteroid strike will need many of the same skills we must hone to tackle climate change and future pandemics

Voyager 2 flew by Uranus in 1986, giving us our only up-close look at the planet – but unusual space weather just before the craft arrived has given us a misleading idea about the planet’s magnetic field

Anil Ananthaswamy's Why Machines Learn: The elegant maths behind modern AI explores the mechanics of the AI revolution, but doesn't examine its ethics

AlphaProof, an AI from Google DeepMind, came close to matching the top participants in a prestigious competition for young mathematicians

A robot can hold a squash, pumpkin or melon in one hand, while it is peeled by the other

Electromagnetic radiation leaking from the cable between your computer and monitor can be intercepted and decoded by AI to reveal what you are looking at

In Still Wakes the Deep, you play as a Glaswegian electrician on a 1970s oil rig. The well-crafted setting gives way to horror, but I wish I could linger in mundanity for longer, says Jacob Aron

Many people enjoy the experience of using AIs like ChatGPT or voice assistants like Alexa to find out information, but it turns out doing so makes it less likely you will spot inaccurate information

Devices that let people with paralysis walk and talk are rapidly improving. Some see a future in which we alter memories and download skills – but major challenges remain

To address the problem of AIs generating inaccurate information, a team of ethicists says there should be legal obligations for companies to reduce the risk of errors, but there are doubts about whether it would work

Plans to create an interactive AI model of the legendary code breaker Alan Turing are reckless and problematic, says Matthew Sparkes

AI companies hope that feeding ever more data to their models will continue to boost performance, eventually leading to human-level intelligence. Behind this hope is the "transformer", a key breakthrough in AI, but what happens if it fails to deliver?

Computer code dating back to the 1960s is still vital to banks, airlines and governments, but programmers familiar with the language are in short supply. Now AI models are being trained to fill the skills gap

AI tools could help eliminate human bias in forensic investigations, say UCL scientists, who are using eye-tracking technology to study decision-making in skeletal analysis and crime scene examinations

A cyberterrorism charge in Pakistan connected to riots in the UK illustrates how authorities are reaching across borders to tackle disinformation, but bringing overseas suspects to justice won't always be possible

A neural network can recreate the classic computer game Doom despite using none of its code or graphics, hinting that generative AI could be used to create games from scratch in future
