How an AI robot smashed human world record in Labyrinth, a classic marble maze game
You’ve probably heard of AI winning against humans in games like chess and GO that require intellect. That’s impressive but not shocking.
AI is good at crunching numbers and finding patterns.
But what about physical skills? That’s something humans are supposed to be better at, right? Well, not anymore.

An AI labyrinth maze champion emerges
Researchers at ETH Zurich have created an AI robot with the task of learning how to play the popular wooden labyrinth maze game. The goal of the game is simple, using two knobs, you have to steer a marble ball from a start to an endpoint without it falling into the holes across the board. But if you’ve ever played it, you know it’s actually easier said than done. The scientific explanation behind its difficulty is that it requires acute motor skills, spatial reasoning abilities — and a lot of practice.

Meet the new robot champion
The robot, named CyberRunner, is equipped with two motors (its hands), a camera (its eyes), and a computer (its brain), allowing it to play the game just like a person would. Much like a human, CyberRunner learns through experience by leveraging recent advances in model-based reinforcement learning, which enables the AI to make decisions and choose potential successful behaviors by predicting the outcomes of different courses of action.

While playing the game, CyberRunner makes observations of the labyrinth and receives rewards based on its performance. It keeps a memory of the collected experience, or as we humans call it, “practice,” which the algorithm uses to learn how the system behaves.
Based on this knowledge, it’s able to recognize the most promising behaviors. As a result, the robot’s use of the two motors continuously improves, and CyberRunner keeps getting better while the algorithm runs every time it plays.

The triumph of the robot in breaking the human record
The robot received 6.06 hours of practice. Impressively, it beat the previous world record set by Lars Göran Danielsson, who set a time of 15.41 seconds in 2022. CyberRunner completed the game in 14.48 seconds — faster by over 6% compared to the human record holder.

During the learning process, the researchers say the robot discovered shortcuts and found ways to cheat — a behavior that they are studying as an innate human trait. Therefore, the researchers had to step in and instruct CyberRunner not to skip parts of the maze.

What can be learned from CyberRunner?
Researchers Thomas Bi and Raffaello D’Andrea are making available the robotic system’s hardware and software open-source so that others can benefit and learn from their breakthrough in AI skill acquisition. They want to spur other scientists and engineers to use their experiment as an opportunity to conduct their own research. For those interested, their research paper is available here.
Kurt’s key takeaways
CyberRunner’s victory marks a significant milestone in the field of artificial intelligence, demonstrating that AI can now outperform humans not only in tasks that involve information processing but also in physical skill games. The project’s open-source approach ensures that the benefits of this achievement are accessible to a wider audience, paving the way for further innovations in real-world machine learning and AI. As we witness AI breaking new ground, the line between human and machine capabilities continues to blur.

Congress just gave DHS another $70 billion
Congress narrowly voted to fund President Donald Trump’s mass deportation agenda, giving the Department of Homeland Security $70 billion over the next three years.
The house voted 214 to 212 in favor of the reconciliation bill Tuesday, following the Senate’s 52-47 vote last Friday morning. The vote fell largely along party lines. Sen. Lisa Murkowski (R-AK) was the only Senate Republican to vote against it. Rep. Tim Walberg (R-MI), initially voted against the bill — meaning it would have failed — but changed his vote after huddling with House Majority Leader Steve Scalise (R-LA) and Appropriations Chair Tom Cole (R-OK), according to The Hill. No Democrats voted in favor of the funding bill, which was done through a budget reconciliation process to avoid a Democratic filibuster.
In a speech on the House floor ahead of the Tuesday vote, Rep. Mary Gay Scanlon (D-PA) criticized Republicans for using the budget reconciliation process to avoid negotiating with Democrats, and emphasized ICE’s lack of popularity with the American people.
“At its core, this Republican reconciliation budget bill is a statement about priorities, and the priorities represented in this budget bill could not be more out of step with the needs and values of the American people,” Scanlon said.
Scanlon noted that DHS has yet to spend $100 billion of the nearly $200 billion it received under Trump’s One Big Beautiful Bill Act. She added that Trump has not only expanded ICE’s reach by increasingly going after legal immigrants but also weaponized DHS against its critics. The bill, she said, will “supercharge” Trump’s abuses.
After the House markup last Friday, Rep. Rosa DeLauro (D-CT), ranking member of the House Appropriations Committee, noted that the bill not only lacks sufficient reforms but also cuts funding for cybersecurity and TSA, whose workers went weeks without pay during the DHS shutdown.
The funding bill comes at a time of deep unpopularity for ICE. One recent poll found that just 33 percent of voters approve of how the agency is doing its job.
And it comes amid yet another threat from border czar Tom Homan to flood New York City with ICE agents. In an interview with Fox News on Monday, Homan said he would send “more ICE agents than you’ve ever seen” to New York City if the state government passed a bill limiting cooperation with DHS.
“Providing a quarter trillion dollars to an administration promising that the public ‘ain’t seen shit yet’ when it comes to mass deportation is a historic mistake,” Todd Schulte, president of the immigration reform group FWD.us, said in a statement. “Supercharging the funding for these already out of control systems will come with terrible human consequences and continue to be met with increasing opposition from voters.”
Correction, June 9th: A previous version of this story said Rep. Tim Walberg voted against the funding bill. He initially voted against it but then changed his vote to support it.
Update, June 9th: This story has been updated to include comment from FWD.us president Todd Schulte.

8 apps that can help you cut your food bill
NEWYou can now listen to Fox News articles!
Food prices have a way of sneaking up on you. One week, your usual grocery run feels normal. The next week, a few basics suddenly cost a lot more than you expected.
That is why money-saving food apps are worth a closer look. All of these apps are free to download or sign up for, but you still pay for any food, groceries or purchases you make through them.
Some help you find discounted groceries before stores toss them. Others connect you with surprise meals, receipt rewards, free local listings or recipes based on what you already have at home.
The trick is knowing which app fits the way you actually shop. Here are eight apps that can help you stretch your food budget, reduce waste and maybe make your next receipt feel a little less painful.

You browse local deals in the app, pay through the app and pick up your order in the store. Flashfood says shoppers can find grocery deals for up to 50% off. That can include produce, meat, dairy, pantry items and other staples, depending on what stores near you have available.
- Best for: Discounted grocery pickup.
- How you save: Buy marked-down groceries from participating stores before they go to waste.
- Good to know: Availability depends on participating stores near you.
2) Misfits Market
Misfits Market delivers groceries to your door. The company says it offers high-quality rescued foods and lets you choose what goes in your order. After signing up, you receive a weekly shopping window. You can review your cart, remove items, add groceries and skip orders when needed. This can work well if you want grocery delivery and like the idea of reducing food waste at the same time. Misfits Market says there are no subscription fees or order obligations. You can skip, pause or cancel.
- Best for: Grocery delivery with rescued food.
- How you save: Order discounted groceries, including rescued or excess food, delivered to your door.
- Good to know: Delivery depends on your ZIP code. Misfits Market says it serves nearly every ZIP code in the contiguous U.S., with limited service in select areas.
Misfits Market lets you customize grocery deliveries with rescued or excess food that may cost less than traditional shopping.
3) Too Good To Go
Too Good To Go helps you buy surplus food from nearby restaurants, bakeries, cafés and stores. The app uses “Surprise Bags,” which means you usually know the type of food and pickup window, but not every exact item inside. That surprise part can be fun, especially if you like trying local spots. It can also be less ideal if you need a very specific dinner plan. Too Good To Go says users can save and enjoy food at half price or less.
- Best for: Discounted restaurant and bakery food.
- How you save: Buy discounted Surprise Bags from local restaurants, bakeries, cafés and stores.

4) Olio
Olio connects people locally so they can give away food and other useful items. The app says you can browse free food from local shops and neighbors. You may also find books, toys, toiletries and household items. This one feels more community-based than a regular coupon app. It can be especially helpful if you live in an active area where neighbors and local shops often post.
- Best for: Free local food and household items.
- How you save: Find free food and household items shared by neighbors or local businesses.
- Good to know: Results depend heavily on your local community.
5) SuperCook
SuperCook helps you turn the food already in your kitchen into meals. You enter the ingredients you have at home, and the app suggests recipes you can make. That can save money in a different way. Instead of buying more groceries, you may find a way to use the half bag of rice, frozen vegetables or canned beans you already paid for.
- Best for: Using up food you already have.
- How you save: Turn ingredients you already have into meals, so you can avoid another grocery run.
- Good to know: This one does not give cash back. It helps you avoid extra spending and food waste.
6) Ibotta
Ibotta gives you cash back on eligible purchases. Before you shop, you add cash-back offers in the app. After shopping in-store, you submit your receipt. Ibotta says you can withdraw earnings once you reach $20. It’s great because it can work with groceries and other everyday purchases. The key is remembering to add offers before you shop and submit your receipt after.
- Best for: Grocery cash back.
- How you save: Earn cash back on eligible grocery and everyday purchases after you submit receipts.
- Good to know: You need to match the right offers and follow the redemption steps.
7) Fetch
Fetch turns receipts into points. You shop, snap receipts and earn points that can be redeemed for gift cards.

Which app should you try first?
Start with the app that fits your normal routine. If you already shop at grocery stores in person, try Flashfood or Ibotta. If you save receipts anyway, Fetch is an easy add-on. If you order groceries online, Misfits Market may be worth checking. If you like trying local food, Too Good To Go can be a fun way to save. If your fridge is full, but dinner still feels impossible, SuperCook may help you avoid another grocery run. For gas and food cash back in one place, Upside deserves a look. For free local food and community sharing, Olio may surprise you, depending on where you live.
A few smart tips before using food savings apps
Before you download every app on this list, take a moment to think about your habits. First, check whether the app works in your area. Some apps depend on local stores, restaurants or community activity. If there are no nearby offers, the app may not help much yet.
Next, watch pickup windows. Apps like Flashfood and Too Good To Go can save you money, but they also require timing. If you miss the pickup, you may lose the deal. Also, avoid buying food only because it looks cheap. A discounted item saves money only if you actually use it. Finally, read the app’s privacy settings. These apps often work through location, receipts, purchases and rewards accounts. Use only the permissions you feel comfortable sharing.
Kurt’s key takeaways
Food savings apps can help, but they work best when they match your real life. Flashfood and Too Good To Go are great for deal hunters who can pick up food nearby. Misfits Market works better for people who want groceries delivered. Ibotta, Fetch and Upside can help you earn something back from purchases you already make. SuperCook and Olio come at savings from a different angle. One helps you use what you already bought. The other connects you with local people and shops that share food and useful items. The biggest takeaway? Do not let the app make you spend more. Use it as a tool, not a temptation.

Apple dials down Liquid Glass, and the Mac looks way better for it
MacOS 27 Golden Gate will usher in a bunch of changes to the Mac when it’s released later this year, with its biggest new features revolving around Siri AI. But for now, using the first developer beta, Siri AI is only offered through a waitlist. So what’s available to try is mostly about how the upcoming operating system looks and feels.
You’re not welcomed with any fanfare when you boot up the macOS 27 developer beta (that’ll probably come later), but there’s reason to celebrate. Jump to the appearance settings, and you find that Apple now has a Liquid Glass slider, allowing users to set the amount of UI transparency in macOS. On one end of the slider, it’s as seethrough as Liquid Glass gets, and on the other end the transparent accents are heavily frosted. Golden Gate starts you in the middle of the slider by default, for just a touch of frosting — perhaps a gentle admission that the original look went too far. You sadly can’t go fully opaque, but this frosted look does greatly reduce the distracting elements of Liquid Glass.
After spending just a short while with Golden Gate, I already prefer the minimum transparency look. I’d crank that slider in the full version and never turn back. For the strongest Liquid Glass haters out there, the Reduce Transparency option is still available in the Accessibility settings, but using it is like taking a hammer to all that glass — introducing lots of harsh gray and black backgrounds to the dock, Menu Bar, and Control Center.
The absolute wins for macOS 27’s design is the return of edge-to-edge sidebars with colorful icons and the increased corner radii of windows across the OS. The former is basically a backtrack to the way sidebars used to look (which looked better and easier to parse, with less wasted space). And the latter is just logical. How on Earth did Apple get so high on its own design supply that it allowed windowed apps to have mismatched corners?
I do have my nitpicks — the new battery icon taken from iOS is less legible (really, I hate it). Also, after Apple finally added the most basic window snapping feature in Sequoia, it hasn’t refined it one bit. Both Tahoe and now Golden Gate are leaving me wanting better and faster tiling controls like Windows 11, as well as the simple ability to rename virtual desktops. But so far, nothing.
Apple says Golden Gate is supposed to feel snappier, with faster search indexing. It’s too early to tell how much of a difference this makes on the MacBook Neo I’m testing it on — especially since dev betas are notoriously buggy and unstable. Using Spotlight search for local files on Golden Gate performed similar to another Neo I had on-hand running macOS 26 Tahoe. And opening apps on both systems side-by-side led to mixed results: Golden Gate opened Lightroom Classic and Slack faster, but Tahoe was faster to open Photoshop and Steam. I hope Apple’s under the hood improvements to memory and CPU usage will really show on the MacBook Neo, which could use all the efficiency it can get, but the jury’s out for now.
There’s still more to come with further beta releases of macOS 27, where we’ll at some point be able to fully test Siri AI, Visual Intelligence, and the revamped Spotlight Search. Last year’s power user-focused Spotlight with clipboard history was a nice improvement, but I’m skeptical that Siri AI being baked into Spotlight will be quite the gamechanger Apple’s billing it as. I’ll keep an open mind and be looking to find out once I’m off the waitlist.
For now, I’m relieved Apple is slightly backpedaling on Liquid Glass. While the look was never quite as bad on the Mac as it was on iOS, it’s a welcome change to be able to turn down these transparencies and get a little closer to the old looks from Sequoia. That and the other bits of UI polish are a nice upgrade on their own. Now, Apple has to show that it can nail all the new AI features, too — I’m eager to see how it fares.
