Has Trump failed to sell the Iran war to the world? Are US-Israeli attacks against Iran legal? Why did Trump fire Kristi Noem as DHS secretary? United States President Donald Trump is getting into the fusion power business through a $6bn merger of his social media firm and Google-backed TAE Technologies, just days after industry representatives urged federal funding. The all-stock deal, announced on Thursday, is an ambitious bet on the power boom spurred by artificial intelligence (AI) data centres and adds to the Trump family's growing roster of diverse ventures from cryptocurrency to real estate holdings and mobile services.

Authors pictured in order of their interview publication date (left to right, top to bottom). Each year, a small group of PhD students are chosen to participate in the AAAI/SIGAI Doctoral Consortium . This initiative provides an opportunity for the students to discuss and explore their research interests and career objectives in an interdisciplinary workshop together with a panel of established researchers. During 2025, we met with some of the students to find out more about their research and the doctoral consortium experience. Kunpeng Xu completed his PhD at the Université de Sherbrooke and is now a postdoctoral fellow at McGill University.

Welcome to our annual list of the worst, least successful, and simply dumbest technologies of the year. We like to think there's a lesson in every technological misadventure. But when technology becomes dependent on power, sometimes the takeaway is simpler: it would have been better to stay away. Here are some of the more notable ones . Each time you've heard a borderline outlandish idea of what AI will be capable of, it often turns out that Sam Altman was, if not the first to articulate it, at least the most persuasive and influential voice behind it. For more than a decade he has been known in Silicon Valley as a world-class fundraiser and persuader.

The AI boom has caused as much carbon dioxide to be released into the atmosphere in 2025 as emitted by the whole of New York City, it has been claimed. The global environmental impact of the rapidly spreading technology has been estimated in research published on Wednesday, which also found that AI-related water use now exceeds the entirety of global bottled-water demand. The figures have been compiled by the Dutch academic Alex de Vries-Gao, the founder of Digiconomist, a company that researches the unintended consequences of digital trends. He claimed they were the first attempt to measure the specific effect of artificial intelligence rather than datacentres in general as the use of chatbots such as OpenAIâ s ChatGPT and Googleâ s Gemini soared in 2025. The figures show the estimated greenhouse gas emissions from AI use are also now equivalent to more than 8% of global aviation emissions.

Can AI really help us discover new materials? Judging from headlines and social media posts in recent years, one might reasonably assume that AI is going to fix the power grid, cure the world's diseases, and finish my holiday shopping for me. This week, we published a new package called Hype Correction . The collection of stories takes a look at how the world is starting to reckon with the reality of what AI can do, and what's just fluff. One of my favorite stories in that package comes from my colleague David Rotman, who took a hard look at AI for materials research . AI could transform the process of discovering new materials--innovation that could be especially useful in the world of climate tech, which needs new batteries, semiconductors, magnets, and more.

As the world looks to incorporate more renewables into energy grids, centuries-old systems that can balance supply and demand are being reappraised and innovated upon.

Unidentified flying objects [ UFOs ] have been regularly spotted for 13 months above the Jim Bridger Power Plant and Sweetwater County's Red Desert. John Grossnickle, the Sheriff of Sweetwater County, saw lit-up, drone-like objects as recently as December 13, his spokesman Jason Mower told Cowboy State Daily .

Spatial boundaries, such as ecological transitions or climatic regime interfaces, capture steep environmental gradients, and shifts in their structure can signal emerging environmental changes. Quantifying uncertainty in spatial boundary locations and formally testing for temporal shifts remains challenging, especially when boundaries are derived from noisy, gridded environmental data. We present a unified framework that combines heteroskedastic Gaussian process (GP) regression with a scaled Maximum Absolute Difference (MAD) Global Envelope Test (GET) to estimate spatial boundary curves and assess whether they evolve over time. The heteroskedastic GP provides a flexible probabilistic reconstruction of boundary lines, capturing spatially varying mean structure and location specific variability, while the test offers a rigorous hypothesis testing tool for detecting departures from expected boundary behaviors. Simulation studies show that the proposed method achieves the correct size under the null and high power for detecting local boundary shifts. Applying our framework to the Sahel Sahara transition zone, using annual Koppen Trewartha climate classifications from 1960 to 1989, we find no statistically significant decade scale changes in the arid and semi arid or semi arid and non arid interfaces. However, the method successfully identifies localized boundary shifts during the extreme drought years of 1983 and 1984, consistent with climate studies documenting regional anomalies in these interfaces during that period.

Technology Engineering 2,500 'high-risk' U.S. dams are sinking into the ground Radar shows that the damage may be out of sight for inspectors. Breakthroughs, discoveries, and DIY tips sent every weekday. Dams across the United States are in dire need of repairs, and the critical infrastructure may be even worse off than engineers anticipated. According to geoscientists, over 2,500 of the more than 16,700 structures in the country are classified as high hazard potentials and in "poor condition." This classification means that the dams that would cause significant death and destruction if compromised.
