    X-energy and its helium-cooled nuclear reactors
    X-energy is developing small modular reactors to satisfy some of the planet’s most power-hungry users: industrial manufacturers that need high temperatures to produce billions of tons of concrete, plastics, fibers, and chemicals.
    Solar panels and wind turbines are great at producing electricity but what heavy industry also needs is raw heat—and lots of it. The manufacture of concrete, glass, and steel, as well as the production of many chemicals, plastics, and fertilizers, are

    Weight-loss drugs show signs of slowing biological aging, say drugmakers
    Popular weight-loss drugs may do more than help people shed pounds. They might also melt away the years.Drug giants Eli Lilly and Novo Nordisk say patients taking their drugs age less quickly, according to readouts from molecular “aging clocks.”Such clocks assess a person’s biological age by looking at changes to DNA that accumulate with time, or, in newer versions, by tracking levels of key proteins.Both companies found that overweight or diabetic patients taking the drugs, ca

    WeLion New Energy and its semi-solid-state batteries
    WeLion New Energy is on a quest to make safer, better batteries. The company’s semi-solid-state cells could improve safety and offer greater energy density than lithium-ion batteries to power electric cars, boats, and drones.
    From the EVs that carry commuters home to the ships that transport goods across countries, more and more vehicles around us are powered by batteries. Lithium-ion batteries are commonly used to power personal devices and vehicles today. But as the need for batter

    WaveSave and its portable rubber dam
    As sea levels rise and flood risks worsen due to global warming, WaveSave’s easy-to-erect portable dam offers a quick-response tool. People can use the dam to protect themselves and their property, and it can also store freshwater for later use. Communities in Europe, Africa, and Southeast Asia have deployed it successfully. Now, the company is expanding into other water-related services to help vulnerable places become more resilient.

    Moment Energy and its shipping containers packed with old EV batteries
    Demand for energy storage is surging, with capacity expected to grow eightfold in the next decade. To meet that demand, Moment Energy wants to shortcut a supply chain that now flows largely through China, by domestically repurposing EV batteries into new grid-connected storage systems.
    Moment Energy’s four founders met while studying mechatronics engineering in college and worked together on a team that built and raced electric cars. After graduating, they scattered to companies including

    Here’s how our climate team picked 10 promising companies to watch
    As the team at MIT Technology Review set out to choose companies for this year’s edition of our annual list of Climate Tech Companies to Watch, the challenge felt more daunting than any year since we started compiling the list in 2023. This year is shaping up to be one of the hottest ever recorded. The world must begin to reduce greenhouse-gas emissions to address the climate crisis, which is already affecting communities around the globe. Wildfires, floods, and other climate-fueled d

    Form Energy and its iron batteries
    Form Energy is building iron-based batteries that can store energy for multiple days. The company is ramping up supply at its factory and signing deals for commercial projects.
    New solar and wind installations produce electricity more affordably than fossil fuels in most places, but their output varies based on season, time of day, and weather. To compensate, utilities are increasingly investing in battery storage systems, which can charge when power is abundant and discharge when the grid need

    Energy Dome and its carbon dioxide batteries
    There’s a growing need for long-duration storage to meet energy demand and balance out renewables on the grid. Energy Dome uses compressed carbon dioxide gas in its massive grid batteries, which can deliver power for up to 24 hours. 
    As the world races to meet growing electricity demand, solar and onshore wind power have become the cheapest and quickest-to-deploy sources to install on the grid. But, despite their upsides, both are subject to variations in weather patterns, which mean

    Brimstone and its one-stop process for making cleaner cement and critical minerals
    Brimstone is making strides on two industrial problems, reducing the emissions from cement and providing a way to produce more critical minerals within the US. If the company can do both, with the same rocks in the same plant, it would unlock a cleaner and more efficient process for manufacturing building materials, aluminum, steel, and more.
    Brimstone is a code-switching climate tech company for these polarized political times. The US-based startup—part green cement company, part critica

    BasiGo and its fleet of electric buses
    BasiGo aims to replace the tens of thousands of diesel-powered buses on sub-Saharan African roads with electric ones that generate far fewer emissions. The company’s pay-as-you-drive business model has helped make EVs more attainable and is changing the way public transport operates.
    In a bid to contain the covid-19 pandemic in 2020, the Kenyan government temporarily suspended public transportation. The suspension lasted only three days, yet the change in air quality was dramatic. The air

    Connecting AI agents to enterprise knowledge
    For all the data that AI systems continually amass and analyze, enterprise AI agents often suffer from a curious shortcoming: a lack of knowledge. More than data, knowledge is the understanding of what the data means in the context of individual organizations. AI agents need this understanding to reason about situations, make decisions, and ultimately take actions. Without sufficient knowledge, agents are prone to making flawed and unreliable decisions.
    A lack of knowledge, our research finds, i

    Bringing predictive analytics to the agentic AI era 
    In 2026, the question for enterprise AI is no longer whether predictive models can outperform statistical forecasts—that argument is settled. The big question now is how to enable predictive systems to act on their own conclusions without drifting from business intent. The frontier has moved from prediction to autonomous decision making, and the gap between leaders and laggards is widening accordingly.“Enterprises are done with a backward-looking point of view; they want to be more f

    Over the summer I talked to the CEO of Springboards, a startup building an LLM that’s designed to come up with a wider variety of responses than its mainstream rivals do.

    Enterprise AI is no longer a future ambition. It is in full operational flight. Model capabilities are advancing faster than most organizations can absorb, while the cost of performance continues to fall. Globally, AI investment is set to reach $2.5 trillion in 2026, up 44% from the previous year.For many enterprises, this investment has produced fragmentation.

Move 37 in game two of the five-game match looked so absurd that some commentators thought it was a programming glitch. It wasn’t.
