Science in the modern era is increasingly reliant on enormous datasets and automated analysis. In astronomy, the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) – a ten-year survey covering the entire southern sky almost a thousand times over the next decade – will test the limits of this reliance. The Rubin Observatory, located on a mountaintop called Cerro Pachón in Chile, is expected to catalogue the night sky in exquisite detail. The observatory aims to answer a number of questions about the universe by studying different phenomena in the sky, including supernovae (exploding stars), asteroids, dark matter and…

K-12 teachers and students across the country are increasingly using AI in and out of classrooms, whether it is teachers turning to AI to refine lesson plans or students asking AI to help them research a particular topic. An estimated 85% of K-12 public school teachers recently reported that they used AI during the 2024-2025 school year – often for curriculum and content development. In 2023, 13% of teens said they used ChatGPT to complete their schoolwork, while 26% of them said in 2025 that they were using ChatGPT for this purpose. Similarly, 86% of K-12 students shared in 2025 that they have used AI in general.…

I remember the first time I attended a linguistics lecture as an undergraduate in Argentina. The lecturer asked a simple question: Where does language come from? My instinctive answer was: books. After four decades of researching language and linguistics, that response now seems almost absurd. But it reflects a common bias among those of us raised in text-based cultures. We tend to view written language as the ultimate form of expression, knowledge transmission, and even thinking itself. Yet linguists know that speech comes first – historically, developmentally and cognitively. Writing is a relatively recent technological invention layered on top of something much…

It’s a familiar feeling: You start a text message, and your phone’s auto-complete function suggests several choices for the next word, ranging from banal to hilarious. “I love…” you, or coffee? Or you’re finishing an email, and merely typing the word “Let” prompts your app to suggest “Let me know if you have any questions” in light grey text. Predictive language technologies have become so routine – baked into smartphones, email services and chatbots – that we barely notice them anymore. But they raise a difficult question: What happens to a writer’s unique voice when AI routinely completes their thoughts – or…

I was early to the generative AI wave in higher education: I was among the first professors who teach writing to publish in an academic journal about generative AI and critical thinking, and I am now part of an interdisciplinary team at Babson College thinking about how AI is impacting education, industry and society. But that does not mean I am all in on AI – nor am I anti-AI. I am pro-learning. As my co-authors and I argue in a forthcoming book on realising the promise of higher education, even the most powerful tools are only as good as the learning environments we…

In the past few months, a wave of tech corporations has announced significant staff cuts and attributed them to efficiency gains driven by artificial intelligence (AI). Companies such as Atlassian, Block and Amazon have announced they would lay off thousands of employees due to increased reliance on AI. The narrative these companies offer is consistent: AI is making human labour replaceable, and responsible management demands adjustment. The evidence, however, tells a more nuanced story.

This past Christmas, I helped my parents choose a water filter. The latest “smart” models all came with a smartphone app that promised to monitor filter life, track water quality and automatically request service. Yet my father, age 75, and mother, 67, were quick to reject them in favour of a nondigital model. “Every time it updates or I forget how to use it, we’ll have to call you,” my dad said. As an only child living 8,000 miles (12,875 kilometres) away, I didn’t need convincing. My parents are ageing in place and don’t need traditional caregiving – they cook,…

When most people think about the internet, they likely picture websites and apps. What they rarely see are the invisible services that make those experiences possible: systems that translate names into numbers, verify who you are, deliver messages and block malicious traffic. For example, DNS, the Domain Name System, has quietly become a single point of failure. DNS is the Internet’s phone book. When it fails, large parts of the internet effectively disappear, even if servers are still running. DNS is not alone. Over the past decade, four core internet services – DNS, authentication, email and security infrastructure – have consolidated…

Artificial intelligence (AI) already affects many areas of daily life, including the lives of young children. Many families give screens to children younger than two, and AI-generated content is increasing on the popular YouTube Kids channel – and it plays automatically. Most parents are not able to monitor everything their child sees online. Some AI-generated content can be both frightening and attractive to young children, including violence and sexual content using engaging animals and characters. Early childhood education centres are also using AI to support learning, particularly for children with developmental differences. This includes those who do not learn to speak easily or who have other…

Even with no fur in frame, you can easily see that a photo of a hairless Sphynx cat depicts a cat. You wouldn’t mistake it for an elephant. But many artificial intelligence (AI) vision systems would. Why? Because when AI systems learn to categorise objects, they often rely on visual cues – like surface texture or simple patterns in pixels. This tendency makes them vulnerable to getting confused by small changes that have little effect on human perception. A vision system aligned more closely with human perception – one that perhaps emphasises shape, for instance – might still confuse the cat…
