Despite being declared the third-hottest year on record, 2025 was a relatively quiet year for climate disasters in the US. No major hurricanes made landfall, while the total number of acres burned in wildfires last year--a way of measuring the intensity of wildfire season --fell below the 10-year average. But starting this week, the West is experiencing what looks to be a record-breaking heat wave, while forecasting models predict that a strong El Niño event is likely to emerge later this year. These two unrelated phenomena could set the stage for a long stretch of unpredictable and extreme weather reaching into next year, compounding the effects of a climate that's getting hotter and hotter thanks to human activity. Beginning this week and heading into next, a massive ridge of high-pressure air will bring record-breaking temperatures to the American West.

Amazon's Alexa has had an AI upgrade. Now she's got more to say Amazon's Echo smart speaker - more commonly known as Alexa - is getting an AI-powered upgrade which will roll out across the UK. Alexa+ turns the digital assistant into a more chatty device which Amazon says will be able to follow threads and be more proactive in its responses. There has been criticism the Echo has stagnated since its launch in 2016, while AI chatbots like ChatGPT, Gemini and Claude have become much easier to communicate with. It will be interesting to see how users react to this - we expect this could be polarising, with some enjoying the more relaxed, familiar interactions while others may find it disconcerting, said Jessica Miller, head of data insights at FDM/CCS Insight. UK consumers will notice an immediate difference, she added.

Since the conflict in the Middle East began on Feb. 28, Emirates has cancelled more than 2,000 flights -- 54% of scheduled services, according to data from Cirium. As Emirates flight EK10 from London cruised over Saudi Arabia on Monday, news broke of a drone strike at its destination, Dubai. The aircraft turned back to Gatwick, flight data shows, completing a 9,100 km round trip -- one of dozens of flights to nowhere triggered by the Middle East war. Roughly 30 Emirates flights heading to Dubai International Airport were also ordered back or rerouted after Iranian drone attacks temporarily shut what is normally the world's busiest airport for international passengers. Passengers expecting a dawn landing in the glitzy United Arab Emirates port city were stunned. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

Humour and science fiction may not seem obvious bedfellows but a history of cinema will tell you different. Think Spaceballs, Mars Attacks! and Everything Everwhere All At Once to name but a few. And now Ryan Gosling is hopping on board. The 45-year-old is both the lead actor and producer of Project Hail Mary, a space adventure film based on the 2021 Andy Weir novel of the same name. While Gosling has showcased his comedy chops in films such as Barbie and Nice Guys, he tells the BBC he's always struggled as an actor because I would want to bring humour to something but has found opportunities to be funny limited with some projects.

Understanding when learning is statistically possible yet computationally hard is a central challenge in high-dimensional statistics. In this work, we investigate this question in the context of single- and multi-index models, classes of functions widely studied as benchmarks to probe the ability of machine learning methods to discover features in high-dimensional data. Our main contribution is to show that a Noise Sensitivity Exponent (NSE) - a simple quantity determined by the activation function - governs the existence and magnitude of statistical-to-computational gaps within a broad regime of these models. We first establish that, in single-index models with large additive noise, the onset of a computational bottleneck is fully characterized by the NSE. We then demonstrate that the same exponent controls a statistical-computational gap in the specialization transition of large separable multi-index models, where individual components become learnable. Finally, in hierarchical multi-index models, we show that the NSE governs the optimal computational rate in which different directions are sequentially learned. Taken together, our results identify the NSE as a unifying property linking noise robustness, computational hardness, and feature specialization in high-dimensional learning.

Understanding the distance between human languages is central to linguistics, anthropology, and tracing human evolutionary history. Yet, while linguistics has long provided rich qualitative accounts of cross-linguistic variation, a unified and scalable quantitative approach to measuring language distance remains lacking. In this paper, we introduce a method that leverages pretrained multilingual language models as systematic instruments for linguistic measurement. Specifically, we show that the spontaneously emerged attention mechanisms of these models provide a robust, tokenization-agnostic measure of cross-linguistic distance, termed Attention Transport Distance (ATD). By treating attention matrices as probability distributions and measuring their geometric divergence via optimal transport, we quantify the representational distance between languages during translation. Applying ATD to a large and diverse set of languages, we demonstrate that the resulting distances recover established linguistic groupings with high fidelity and reveal patterns aligned with geographic and contact-induced relationships. Furthermore, incorporating ATD as a regularizer improves transfer performance in low-resource machine translation. Our results establish a principled foundation for testing linguistic hypotheses using artificial neural networks. This framework transforms multilingual models into powerful tools for quantitative linguistic discovery, facilitating more equitable multilingual AI.

The reported use of Claude in recent military operations has shifted the Overton window around A.I. in warfare--and sparked a battle between Anthropic and the Department of War. The staff writer Gideon Lewis-Kraus joins Tyler Foggatt to discuss the escalating standoff between the A.I. company Anthropic and the Department of War. They consider recent reporting on the use of Claude--Anthropic's family of large language models--in military operations in Venezuela and Iran, and how that news has pushed the company's relationship with the Pentagon to a breaking point. They also explore how the tech industry is responding to the conflict between the Trump Administration and Anthropic, and the thorny question of whether A.I. should be subject to greater safeguards and more oversight than previous technological innovations.

While Christopher Columbus is hailed as the first in 1492, archaeologists uncovered a small terracotta head of a bearded man carved with distinctive European features tucked inside a Mexican tomb. The artifact, known as the Tecaxic-Calixtlahuaca Head, was discovered in 1933 inside a sealed pre-Hispanic burial beneath multiple intact layers, indicating it had not been disturbed after its placement. Experts say its facial features, beard style and craftsmanship bear a striking resemblance to objects from the ancient Mediterranean rather than indigenous Mesoamerican traditions.

Sony removes 135,000 'deepfakes' of its artists' music Music giant Sony Music says it has requested the removal of more than 135,000 songs by fraudsters impersonating its artists on streaming services. The so-called deepfakes were created using generative AI, and targeted some of the company's biggest acts, who include Beyoncé, Queen and Harry Styles In the worst cases, [the deepfakes] potentially damage a release campaign or tarnish the reputation of an artist, said Dennis Kooker, president of Sony's global digital business. The company says the number of songs generated in this fashion is only increasing as artificial intelligence technology becomes cheaper and easier to access. It believes the 135,000 tracks it has discovered to date represents just a percentage of the total uploaded to streaming services. Since last March alone, it has identified some 60,000 songs falsely purporting to feature artists from their roster.

Computer says no. Are AI interviews making it harder to get a job? It's brutal, says Bhuvana Chilukuri - a third-year business student who has applied for more than 100 jobs and has been rejected for every one. There are moments where I applied and I got a rejection less than two minutes later, which is really horrible, says the 20-year-old. She is convinced that very few, if any, of her applications are ever seen by a human as firms are increasingly using Artificial Intelligence (AI) to hire new staff. The first step is AI screening your CV.
