How future food domes could change the way you eat

NEWYou can now listen to Fox News articles!

A futuristic food dome at Expo 2025 Osaka-Kansai offered a surprising look at how cities may grow fresh food close to home.

Inspired by a classic greenhouse, the Inochi no Izumi or Source of Life dome showed how a compact closed-loop ecosystem could sit on rooftops or in small urban spaces. It looked like a tiny house full of produce powered by nature.

Inside the Source of Life dome

The 21-foot structure sits on a base with four water zones that support marine fish, brackish species and freshwater species. Their waste creates the nutrients that feed the plant layers above. Microbes convert ammonia into nitrates that plants love.

Above the tanks are four hydroponic tiers. Salt-tolerant greens grow over the seawater tank. Tomatoes and semi-salt-tolerant veggies thrive in the brackish zone. Herbs and lettuce sit above freshwater species like sturgeon. Edible flowers fill the top layer where sunlight hits strongest. The layout functions like an ecological slice from ocean to land instead of floors.

Transparent ETFE panels pull in light and help the dome keep a stable climate. Water pumps send nutrients upward and then return clean water to each tank. The loop creates almost no waste and keeps cycling with little input.

How cities may use systems like this

If these domes scale, cities could spread food production across many rooftops instead of one large farm. That shift boosts resilience and reduces shipping. It also lets people see where their food comes from because it grows within reach.

Why this Dome matters

The dome shows how biodiversity can improve food production. With more plant and aquatic species working together, the system stays stable and feeds itself. It does not rely on soil, open land or predictable weather. Cities with tight spaces can use this kind of setup to grow food right where people live.

Researchers from Osaka Metropolitan University and the Tokyo University of Marine Science and Technology designed the system to copy nature. It follows the same recycling found in healthy wetlands. By letting biology do the work, the system reduces strain on land and water.

What this means for you

This model hints at a future where fresh food sits closer to your kitchen. A dome like this could sit on an apartment building or a school and provide herbs, produce and edible flowers. It cuts travel time from farm to table and gives communities more control over their food supply.

If a storm or disaster blocks access to farms, a closed-loop dome can keep growing. For people with tiny yards or no soil, it offers a realistic way to produce clean food in small spaces.

Kurt’s key takeaways

The Source of Life dome may be a prototype, but it delivers a vivid preview of urban food production. It combines architecture, ecology and aquaculture in a compact package that uses every drop of water. If future cities adopt systems like this, access to fresh food could improve for millions.

Even Trump’s chief of staff was ‘aghast’ at Elon Musk’s deadly USAID cuts

Even Trump’s chief of staff was ‘aghast’ at Elon Musk’s deadly USAID cuts

Wiles says she called Musk on the carpet. “You can’t just lock people out of their offices,” she recalls telling him. At first, Wiles didn’t grasp the effect that slashing USAID programs would have on humanitarian aid. “I didn’t know a lot about the extent of their grant making.” But with immunizations halted in Africa, lives would be lost. Soon she was getting frantic calls from relief agency heads and former government officials with a dire message: Thousands of lives were in the balance.

Wiles continued: “So Marco is on his way to Panama. We call him and say, ‘You’re Senate-confirmed. You’re going to have to be the custodian, essentially, of [USAID].’ ‘Okay,’ he says.” But Musk forged ahead—all throttle, no brake. “Elon’s attitude is you have to get it done fast. If you’re an incrementalist, you just won’t get your rocket to the moon,” Wiles said. “And so with that attitude, you’re going to break some china. But no rational person could think the USAID process was a good one. Nobody.”

OpenAI announces upgrades for ChatGPT Images with ‘4x faster generation speed’

OpenAI announces upgrades for ChatGPT Images with ‘4x faster generation speed’

NEWYou can now listen to Fox News articles!

OpenAI announced an update for ChatGPT Images that it says drastically improves both the generation speed and instruction-following capability of its image generator.

A blog post from the company Tuesday says the update will make it much easier to make precise edits to AI-generated images. Previous iterations of the program have struggled to follow instructions and often make unasked-for changes.

“The update includes much stronger instruction following, highly precise editing, and up to 4x faster generation speed, making image creation and iteration much more usable,” the company wrote.

“This marks a shift from novelty image generation to practical, high-fidelity visual creation — turning ChatGPT into a fast, flexible creative studio for everyday edits, expressive transformations, and real-world use.”

The announcement comes just weeks after OpenAI CEO Sam Altman declared a “code red” in a memo within his company to improve the quality of ChatGPT.

In the document, Altman said OpenAI has more work to do on enhancing the day-to-day experience of its chatbot, such as allowing it to answer a wider range of questions and improving its speed, reliability and personalization features for users, according to The Wall Street Journal.

The reported company-wide memo from Altman comes as competitors have narrowed OpenAI’s lead in the AI race. Google last month released a new version of its Gemini model that surpassed OpenAI on industry benchmark tests.

To focus on the “code red” effort to improve ChatGPT, OpenAI will be pushing back work on other initiatives, such as a personal assistant called Pulse, advertising and AI agents for health and shopping, Altman said in the memo, according to the Journal.

Altman also said the company would have a daily call among those responsible for enhancing ChatGPT, the newspaper added. 

“Our focus now is to keep making ChatGPT more capable, continue growing, and expand access around the world — while making it feel even more intuitive and personal,” Nick Turley, the head of ChatGPT, wrote on X Monday night.

I’ve been waiting years for Animal Crossing’s best new features

I’ve been waiting years for Animal Crossing’s best new features

I never felt done with my Animal Crossing: New Horizons island. Despite playing every day for two years, and racking up 1,700 hours of playtime, I somehow never finished decorating. I had plenty of ideas for my island, sure, but actually implementing them was another story: The decorating and terraforming systems that helped make New Horizons a huge success are also slow, manual, and cumbersome, and my patience for decorating and redecorating had finally worn thin.

Fast-forward a few years, and a very much unexpected update is coming to finally fix some of those pain points. Update 3.0 is launching on January 15th, 2026, alongside the Switch 2 Edition of New Horizons. And while the paid Switch 2 upgrade has some nice-to-haves (like Joy-Con 2 mouse controls for indoor decorating), it’s the free update that brings all the key new features.

I recently attended a virtual preview for the New Horizons upgrade and update, and there are two caveats: I have not yet played either the Switch 2 version or the new free content myself, and it’s hard to gauge the quality of the Switch 2 version’s visual and performance improvements over a Zoom call. (I still have some unanswered questions about the biggest performance issues on the original Switch, like the choppy frame rate on more densely decorated islands.) But seeing the 3.0 additions in action, it was easy to imagine myself finishing my island — or at least an island.

As shown in the October announcement trailer, update 3.0 makes much-needed quality-of-life fixes. You’ll finally be able to craft multiple items at once, and crafting will pull materials from your overall storage instead of your pockets, meaning you won’t have to do a bunch of inventory management just to craft some decor. Then there’s Resetti’s Reset Service, which can help you clean up entire sections of your island instantly so you don’t have to pick everything up individually in order to redecorate. Some players also noticed a very subtle but potentially impactful change to movement while terraforming that should hopefully make it a smoother process. And then, as if to show off those decorating improvements, Nintendo also added Slumber Islands.

Not to be confused with dreams, New Horizons’ online island-sharing feature, Slumber Islands are extra sandboxes for you to decorate and play with, where you can set the time of day and the weather and magically conjure up any item you have in your in-game catalog to decorate with, similar to the Happy Home Paradise DLC. You can build bridges and inclines instantly by talking to Lloid, rather than going through Tom Nook and waiting (or time traveling) a day. And while it seems like terraforming works the same on Slumber Islands, the apparent addition of strafing while terraforming — instead of having to constantly reorient yourself manually — should help at least a little bit. (It’s the first thing I’m going to test on January 15th, that’s for sure.)

For me, the worst part of decorating in New Horizons was having an idea, ordering all the furniture I’d need for it over the course of days, testing out the design, realizing it did not look the way I envisioned, and facing the tedious process of breaking it all down and starting over again brick by brick — or, at the very least, having to push and pull objects around for a while to see if I could make it work. The design process I saw on Nintendo’s Slumber Island during the preview, meanwhile, seemed quicker and smoother. Trying out an idea or aesthetic in that environment doesn’t sound like such a tall order.

Without any hands-on time, I can’t say if it will actually be noticeably easier to design and decorate with the 3.0 update. But I’m excited by the idea that I can go to my Slumber Island scratch pad and try out my designs before committing to them (and the cost in bells to get it all done) on my main island. And maybe, if I really like how it feels to decorate, I’ll make an entire Halloween-themed Slumber Island — the kind of island I’ve wanted to make for years but never did on my main island, where the seasons continue to change and actively ruin the vibe.
