The global outcry over the sexualisation and nudification of photographs – including of children – by Grok, the chatbot developed by Elon Musk’s artificial intelligence (AI) company xAI, has led to urgent discussions about how such technology should be more strictly regulated. But to what extent can technology also be used to prevent this explosion in the generation and sharing of deepfake content of real people, without their knowledge or consent? On January 10, Indonesia became the first country to announce it was temporarily blocking access to Grok, followed soon after by Malaysia. Other governments, including the UK’s, have promised to take action against the chatbot…

Imagine you’re shopping for a dinner party this weekend and you spot some nice, but expensive, bottles of wine. You’re not sure if you can afford them, but before you can even open your banking app to check, a lightweight head-worn wearable has already registered the neural activity involved in your mental calculation. It transmits the data to your phone, which confirms that they’re within your budget. In this scenario, you’d be using neurotechnology. We’re increasingly accustomed to relying on consumer wearables like smartwatches and fitness apps that measure and assess our physical parameters, but for most of us, that’s…

When Elon Musk talks about robotics, he rarely hides the ambition behind the dream. Tesla’s Optimus is pitched as an all-purpose humanoid robot that can do the heavy lifting on factory floors and free us from drudgery at home. Tesla is targeting a million of these robots in the next decade. But is Musk likely to succeed? A few years ago, the thought of a friendly, capable household robot belonged in science fiction. We could imagine machines that danced, shifted boxes or played chess, but not ones that understood us well enough to be genuinely helpful. Then came generative artificial intelligence, or gen AI.…

After a string of dramatic failures, the huge Starship rocket from SpaceX had a fully successful test on Oct. 13, 2025. A couple more test flights, and SpaceX plans to launch it into orbit. A month later, a rival rocket company, Blue Origin, flew its almost-as-large New Glenn rocket all the way to orbit and sent spacecraft on their way to Mars. While these successful flights are exciting news for future missions to the Moon as well as other planets, I’ve argued for several years that these superheavy-lift rockets can also boost research in my own speciality, astronomy – the study of stars and galaxies far beyond our solar system…

One of the first modern coworking spaces, C-Base in Berlin, was launched 30 years ago by a group of computer engineers as a “hacker space” in which to share their tech and techniques. Similarly, many of the people we first encountered in our anthropological research into the emerging world of digital nomadism in the mid-2010s were hackers and computer coders. Nearly a decade later, we returned to Chiang Mai to see what had happened to these pioneers of the borderless, desk-free life. We wondered if they had been put off by the throngs of travellers who have followed in their sandal-clad footsteps, attracted by glamorous…

The amount of renewable energy produced around the world is increasingly exceeding demand – particularly from wind and solar sources. This presents a significant challenge when limited grid capacity and insufficient energy storage mean this clean power has to be curtailed, wasting the excess generation. The scale of this problem is substantial. In the UK, for example, wind farms were forced to curtail 4.3 terawatt (trillion watt) hours of surplus energy – about 5% of their annual output – in 2023. This would have been enough to power 1.5 million homes for the year, so failing to harness it cost bill payers…

When Roro (not her real name) lost her mother to cancer, the grief felt bottomless. In her mid-20s and working as a content creator in China, she was haunted by the unfinished nature of their relationship. Their bond had always been complicated – shaped by unspoken resentments and a childhood in which care was often followed closely by criticism. After her mother’s death, Roro found herself unable to reconcile the messiness of their past with the silence that followed. She shared her struggles with her followers on the Chinese social media platform Xiaohongshu (meaning “Little Red Book”), hoping to help them with…

Switching off can be surprisingly expensive. Much like the smoking cessation boom of the 1990s, the digital detox business – spanning hardware, apps, telecoms, workplace wellness providers, digital “wellbeing suites” and tourism – is now a global industry in its own right. People are increasingly willing to pay to escape the technology they feel trapped by. The global digital detox market is currently valued at around US$2.7 billion (£2bn), and forecast to double in size by 2033. Hardware manufacturers such as Light Phone, Punkt, Wisephone and Nokia sell minimalist “dumb phones” at premium prices, while subscription-based website blockers such as Freedom, Forest, Offtime and RescueTime have turned…

Social media and mobile phones are major disruptors of face-to-face conversations. Recent research has conclusively demonstrated that the indiscriminate (and borderline addictive) use of mobile phones has a direct impact on the quality of our interactions. Our compulsive relationship with these devices drains our attention, preventing us from listening and sustaining meaningful conversation. Studies have found that the mere presence of a mobile phone, even if it is on silent, divides people’s attention. It reduces the likelihood of starting and sharing interesting conversations, as participants subconsciously anticipate the device demanding its owner’s attention at any moment. Accordingly, people often decide to “skim”…

In artificial intelligence, 2025 marked a decisive shift. Systems once confined to research labs and prototypes began to appear as everyday tools. At the centre of this transition was the rise of AI agents – AI systems that can use other software tools and act on their own. While researchers have studied AI for more than 60 years, and the term “agent” has long been part of the field’s vocabulary, 2025 was the year the concept became concrete for developers and consumers alike. AI agents moved from theory to infrastructure, reshaping how people interact with large language models, the systems…
