The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include discovering the earliest and most distant known galaxies, which existed just 300 million years after the Big Bang. Distant objects are also very ancient because it takes a long time for the light from these objects to reach telescopes. JWST has now found a number of these very early galaxies. We’re effectively looking back in time at these objects, seeing them as they looked shortly after the birth of the universe. These…

For almost a decade, researchers have been gathering evidence that the social media platform Facebook disproportionately amplifies low-quality content and misinformation. So it was something of a surprise when in 2023 the journal Science published a study that found Facebook’s algorithms were not major drivers of misinformation during the 2020 United States election. This study was funded by Facebook’s parent company, Meta. Several Meta employees were also part of the authorship team. It attracted extensive media coverage. It was also celebrated by Meta’s president of global affairs, Nick Clegg, who said it showed the company’s algorithms have “no detectable impact on polarisation, political attitudes or beliefs”. But…

For the last year, ChatGPT has been able to analyse images as well as text as a feature of its latest version – GPT-4V(ision). For instance, if you upload a photograph of the contents of your fridge, ChatGPT can describe what’s in the photo and then recommend potential meal ideas based on those ingredients, along with suitable recipes. Or you can photograph a hand-drawn sketch of how you’d like your new website to look and ChatGPT will take that image and provide you with the HTML code to make the site. You can also upload a still frame from part way…

Meta supremo Mark Zuckerberg unveiled Orion smart glasses, a new augmented reality (AR) prototype, at the annual Meta Connect developer conference. Ten years in the making, and still not expected on high streets until 2027, these will be a new way to meld the real and digital worlds. They will be controlled by the eyes and also the fingers via a neural interface on the wrist. So what does this mean for the future of AR wearables and how we interface with computers? We asked three tech specialists at the University of Bangor, Peter Butcher, Llŷr ap Cenydd and Panagiotis Ritsos. Why…

SpaceX has launched its Crew Dragon spacecraft on a “rescue mission” to bring back two astronauts stranded at the International Space Station (ISS) since June. Butch Wilmore and Suni Williams travelled to the space station on Boeing’s Starliner spacecraft, which was on its first mission with a human crew. But several engines malfunctioned once in space and the vehicle was found to be leaking helium, which is essential for the functioning of its engines. After weeks of analysis and discussion by NASA and Boeing engineers, the space agency decided to send Wilmore and Williams home on the Crew Dragon because of safety concerns with Starliner. For Boeing,…

You know we’ve reached peak interest in artificial intelligence (AI) when Oprah Winfrey hosts a television special about it. AI is truly everywhere. And we will all have a relationship with it – whether using it, building it, governing it or even befriending it. But what exactly is AI? While most people won’t need to know exactly how it works under the hood, we will all need to understand what it can do. In our conversations with global leaders across business, government and the arts, one thing stood out – you can’t fake it anymore. AI fluency that is. AI isn’t just about…

As is their tradition at this time of year, Apple announced a new line of iPhones a few weeks back. The promised centrepiece that would make us want to buy these new devices was AI – or Apple Intelligence, as they branded it. Yet the reaction from the collective world of consumer technology has been muted. The lack of enthusiasm from consumers was so evident it immediately wiped over a hundred billion dollars off Apple’s share price. Even the Wired Gadget Lab podcast, enthusiasts of all new things tech, found nothing in the new capabilities that would make them want to upgrade to…

Imagine scrolling through social media or playing an online game, only to be interrupted by insulting and harassing comments. What if an artificial intelligence (AI) tool stepped in to remove the abuse before you even saw it? This isn’t science fiction. Commercial AI tools like ToxMod and Bodyguard.ai are already used to monitor interactions in real-time across social media and gaming platforms. They can detect and respond to toxic behaviour. The idea of an all-seeing AI monitoring our every move might sound Orwellian, but these tools could be key to making the internet a safer place. However, for AI moderation to succeed, it…

In January 2023, a new comet was discovered. Comets are found regularly, but astronomers quickly realised this one, called C/2023 A3 (Tsuchinshan-ATLAS), had the potential to be quite bright. Some hyperbolic reports have suggested it might be the “comet of the century”, but any astronomer will tell you the brightness of comets is notoriously hard to predict. As I explained last year, we’d have to wait until it arrived to be sure how bright it would become. Now, the time has come. Comet C/2023 A3 is currently visible with the naked eye in the morning sky in Australia and Aotearoa New Zealand, with…

Ever found yourself unable to resist checking out a social media notification? Or sending a random picture just to keep a Snapchat “streak” going? Or simply getting stuck staring at YouTube because it auto-played yet another cute cat video? If so, you’re far from alone. And if we adults can’t resist such digital temptations, how can we expect children to do any better? Many digital environments are not designed with the best interest of users in mind – and this is especially true of games, apps and platforms commonly used by kids and teens. Designers use persuasive design techniques to make users…
