A few years ago, if you turned on the heat in an apartment in Helsinki, the energy typically came from coal. But the city’s power company shut down one coal plant in 2023, and the remaining one closed this week—four years earlier than a target set by the national government. “Within two years, we have completely phased out coal,” says Olli Sirkka, CEO of Helen, the power company, which is a subsidiary of the city. The city has one of the world’s biggest district heating systems, with a network of underground pipes filled with hot water that deliver heat to buildings. It takes a huge amount of energy to run. One large chunk of that now comes from wind power, which …

The nonstop cavalcade of announcements in the AI world has created a kind of reality distortion field. There is so much buzz, and even more money, circulating in the industry that it feels almost sacrilegious to doubt that AI will make good on its promises to change the world. Deep research can do 1% of all knowledge work! Soon the internet will be designed for agents! Infinite Ghibli! And then you remember AI screws things up. All. The. Time. Hallucinations—when a large language model essentially spits out information created out of whole cloth—have been an issue for generative AI since its inception. And they are doggedly persistent: Despite advances in model si…

Andy Merolla is a professor in the Department of Communication at the University of California, Santa Barbara. Jeffrey Hall is a professor in the Department of Communication Studies and the director of the Relationships and Technology Lab at the University of Kanas. What’s the big idea? Individually, most day-to-day interactions may seem trivial, but they add up to an important personal and societal opportunity. We all engage in our own unique ecosystem of everyday communication—our very own social biome. Meaningful engagement with others is critical to health and wellbeing, but we live in a time when any kind of engagement is dwindling. So, even if we don’t get ev…

Are you prepared for when the power goes out? To prevent massive wildfires in drought-prone, high-wind areas, electrical companies have begun preemptively shutting off electricity. These planned shutdowns are called public safety power shutoffs, abbreviated to PSPS, and they’re increasingly common. So far this year, we’ve seen them in Texas, New Mexico, and California. Unlike regular power failures, which on average last only about two hours while a piece of broken equipment is repaired, a PSPS lasts until weather conditions improve, which could be days. And these shutoffs come at a steep price. In 2010 alone, they cost California more than $13 billion. A 2019 analysi…

Google released its new Gemini 2.5 Pro Experimental AI model late last month, and it’s quickly stacked up top marks on a number of coding, math, and reasoning benchmark tests—making it a contender for the world’s best model right now. becoming apparent that the new reasoning model may be the best model in the world, at least for now. Gemini 2.5 Pro is a “reasoning” model, meaning its answers derive from a mix of training data and real-time reasoning performed in response to the user prompt or question. Like other newer models, Gemini 2.5 Pro can consult the web, but it also contains a fairly recent snapshot of the world’s knowledge: Its training data cuts off at the e…

Extreme weather is dangerous weather, and that’s particularly true for the heavy rainfall events that experts say are becoming more frequent with climate change. The powerful storms can pose threats ranging from falling limbs to downed power lines to drowning. Experts say disaster preparation and good planning can help protect lives and property. What should you do if you face record rainfall? Long before extreme weather happens, it’s important to consider whether your home meets building codes, and to know what your insurance covers, experts say. This is the time to address any shortcomings. Once storms draw near, stay informed by signing up for real-time …

Another day, another recall: On Tuesday, popular chocolate brand Tony’s Chocolonely recalled two of its bars, Tony’s Dark Almond Sea Salt Bar (6.35oz) and Everything Bar (6.35oz), following 12 reports from consumers who found small stones “not filtered during third-party almond harvesting and the almond processing process.” The bars were distributed nationwide from February 7 to March 24, 2025 and sold in various retail stores, as well as at Tony’s online store. “We are extremely sorry to have to issue this recall, and for the inconvenience that this will cause,” a company spokesperson told Fast Company. “Whilst the probability of a product being affected is low, …

When assessing home price momentum, it’s important to monitor active listings and months of supply. If active listings start to rapidly increase as homes remain on the market for longer periods, it may indicate pricing softness or weakness. Conversely, a rapid decline in active listings could suggest a market that is heating up. Generally speaking, local housing markets where active inventory has returned to pre-pandemic levels have experienced softer home price growth (or outright price declines) over the past 30 months. Conversely, local housing ma…

Influencing has a major pay gap, and it’s not what you might expect. A new report from Collabstr, based on over 15,000 influencer collaborations using first-party data, reveals a surprising disparity: male creators earn 40% more per collaboration than female creators—$291 compared to $208 on average. This gap persists despite women making up the majority of the content creator space. In 2024, 72% of influencers are women, up from 70% in 2023. These two facts are connected. The report, which focused predominantly on nano and micro-influencers, suggests that female creators are paid less largely due to the sheer number of women in the industry. Oversaturation d…

TikTok is shutting down TikTok Notes—wait, you didn’t even know it existed? Well, that explains a lot. TikTok Notes, the platform’s short-lived attempt to take on Instagram (just as Instagram Reels was built to mimic TikTok), is officially being retired. Launched in limited markets like Canada, Australia, and Vietnam last year, the photo-sharing app let users post images with captions—simple enough, but apparently not compelling enough. Users are now being notified that TikTok Notes will shut down on May 8, with TikTok instead shifting focus to another ByteDance-owned platform: Lemon8. “We’re excited to bring the feedback from TikTok Notes to Lemon8 as we cont…

The Panama Canal is one of the most important waterways in the world, with about 7% of global trade passing through. It also relies heavily on rainfall. Without enough freshwater flowing in, the canal’s locks can’t raise and lower ships traveling between the Atlantic and Pacific oceans. Droughts mean fewer ships per day, and that can quickly affect Panama’s finances and economies around the world. But the same freshwater is also essential for Panama’s many other needs, including drinking water for about two million Panamanians, use by Indigenous people and farmers in the watershed, as well as hydropower. When the region experiences droughts, as it did in 2023–2024…

Welcome to AI Decoded, Fast Company’s weekly newsletter that breaks down the most important news in the world of AI. You can sign up to receive this newsletter every week here. OpenAI says it will release an open-source model–but why now? OpenAI CEO Sam Altman said Monday that his company intends to release a “powerful new open-weight language model with reasoning” in the next few months. That would mark a major shift for a company that has kept its models proprietary and secret since 2019. The announcement wasn’t a total surprise: After the groundbreaking Chinese open-source model DeepSeek-R1 showed up in January, Altman said during a Reddit AMA that he realized…

One of the world’s most iconic and controversial maps just got a major redesign. The Metropolitan Transportation Authority (MTA) in New York has unveiled the final version of an updated map of its subway system, marking the first time the map has had a full redesign since 1979. It’s a visually bold, user-centric design that, according to the MTA, will make it easier for people to understand where they’re going and how to use the system. The new maps are expected to be installed in train cars and stations over the next few weeks. The map features bright, color-coded lines for each train line, which criss-cross a stylized map of the city in horizontal, vertical, and dia…
