IFA 2025: the biggest tech and gadget announcements

IFA, the European tech trade show equivalent to CES in the US, is just around the corner. Companies are gearing up to showcase their latest innovations, bringing us the latest product announcements, feature demonstrations, and design concepts that will shape future consumer tech releases. IFA will open its doors between September 5th and 9th, but many of the biggest announcements will start dropping shortly before the show’s public opening. And, as always, The Verge will be covering all the lat

Finnish City Inaugurates 1 MW/100 MWh Sand Battery

Support CleanTechnica's work through a Substack subscription or on Stripe There are more ways to store energy than just using batteries. Some are using fire bricks, particularly for process heat for industries that rely on high heat in manufacturing. Others propose an arrangement of massive concrete blocks that move up and down like the weights of a giant grandfather clock, converting kinetic energy to potential energy and back again. In Finland, two intrepid engineers began experimenting with

Physically based rendering from first principles

Physically based rendering from first principles In this interactive article, we will explore the physical phenomena that create light and the fundamental laws governing its interaction with matter. We will learn how our human eyes capture light and how our brains interpret it as visual information. We will then model approximations of these physical interactions and learn how to create physically realistic renderings of various materials. Chapter 1: What is light? We are all familiar with li

Attributes This element includes the global attributes. shadowrootmode Creates a shadow root for the parent element. It is a declarative version of the Element.attachShadow() method and ac

Stressed Ice Generates Electricity, Researchers Find

Don’t mess with ice. When it’s stressed, ice can get seriously sparky. Scientists have discovered that ordinary ice—the same substance found in iced coffee or the frosty sprinkle on mountaintops—is imbued with remarkable electromechanical properties. Ice is flexoelectric, so when it’s bent, stretched, or twisted, it can generate electricity, according to a Nature Physics paper published August 27. What’s more, ice’s peculiar electric properties appear to change with temperature, leading researc

Apple releases beta 9 for iPadOS 26, tvOS 26, watchOS 26, more

Apple has just released another wave of beta updates for its forthcoming major software versions, including beta 9 for iPadOS 26, tvOS 26, and more. New beta 9 builds available for Apple’s major new OS versions Based on prior years’ patterns, last week’s beta 8 updates from Apple were widely expected to be the last releases before next week’s RC (release candidate) versions. Today, however, the company shipped a wave of beta 9 updates. New beta 9 releases include: iOS 26 iPadOS 26 macOS T

Scientists Pinpoint Cause of Mysterious Electrical Surges on Satellites

In 1994, two Canadian TV satellites failed within mere hours of each other. The pair was in a geostationary orbit when a major solar storm hit, resulting in electrostatic discharges that disabled their control electronics. Anik E1 and E2 are just one example of the effects of electric charge buildup on satellites, known as spacecraft environment discharge. New findings show a direct correlation between a spacecraft’s electric discharge and peaks in the flux of electrons in space, identifying hu

Removing Guix from Debian

Removing Guix from Debian [LWN subscriber-only content] As a rule, if a package is shipped with a Debian release, users can count on it being available, and updated, for the entire life of the release. If package foo is included in the stable release—currently Debian 13 ("trixie")—a user can reasonably expect that it will continue to be available with security backports as long as that release is supported, though it may not be included in Debian 14 ("forky"). However, it is likely that the Gui

Static sites enable a good time travel experience

Varun wrote about gamifying blogging and personal website maintenance which reminded me of the time when I awarded myself some badges for blogging. I mentioned this to Varun who asked if I had any screenshots of what it looked like on my website. My initial answer was “no”, then I looked at Wayback Machine but there were not pictures of the badges. Then, a bit later it hit me. I don’t need any archived screenshots: my website is built with Eleventy and it's static so I can check out a git comm

WordPress shows off Telex, its experimental AI development tool

Web publishing platform WordPress is introducing an early version of an AI development tool, which CEO Matt Mullenweg described as a “V0 or Lovable, but specifically for WordPress” — V0 and Lovable being references to popular “vibe coding” services for building software using prompt-based, AI interfaces. Mullenweg introduced the new WordPress AI tool, called Telex, at the company’s WordCamp US 2025 conference in Portland last week, alongside other AI experiments. During his keynote address, Mul

Porsche’s next Cayenne is fully electric—we drove the prototype

Porsche provided flights from Albany to Barcelona and accommodation so Ars could drive a prototype Cayenne Electric. Ars does not accept paid editorial content. Curved displays in cars are increasingly common, adding a bit of shape to the increasing pixel overload we face behind the steering wheel. The designers of Porsche's upcoming Cayenne Electric, though, decided to do something more dramatic with the touchscreen that commands the center of the forthcoming SUV's dashboard. Its shape flows

Delete, Delete, Delete: How FCC Republicans are killing rules faster than ever

The Federal Communications Commission's Republican chairman is eliminating regulations at breakneck speed by using a process that cuts dozens of rules at a time while giving the public only 10 or 20 days to review each proposal and submit objections. Chairman Brendan Carr started his "Delete, Delete, Delete" rule-cutting initiative in March and later announced he'd be using the Direct Final Rule (DFR) mechanism to eliminate regulations without a full public-comment period. Direct Final Rule is

Home Depot's Infamous Skelly Has a Voice This Halloween Thanks to a New App

With Labor Day marking the unofficial end of summer, it's time to start thinking about setting up your Halloween decorations. And this year, Home Depot's infamous giant skeleton returns with an app that gives the new Ultra Skelly a voice and fresh moves to spook trick-or-treaters. Make no bones about it: Skelly's going high tech. The new animatronic version is shorter than the original, at 6.5 feet tall, but you can freak out your whole neighborhood with this skeleton's rotating upper torso, mo

Galaxy Z Fold 5, Flip 5 owners are get their first taste of One UI 8

Ryan Haines / Android Authority TL;DR The One UI 8 beta has started rolling out to the Galaxy Z Fold 5 and Galaxy Z Flip 5 foldable phones. This beta release seems to be restricted to Korea for now. This comes after Samsung recently brought the One UI 8 beta to the Galaxy S23 series and some Galaxy A phones. Samsung has just brought the One UI 8 beta to the Galaxy S23 series and a few other phones. However, there’s good news if you’ve got a Galaxy Z Fold 5 or Galaxy Z Flip 5 and were waiting

Circle to Search could be adding new Translate options (APK teardown)

Rita El Khoury / Android Authority TL;DR Our teardown of the latest Google app beta reveals that Google is testing more changes to the Circle to Search UI. The Translate shortcut following a selection may move to a more prominent spot. A new “Change selection” button would appear in the same section after you’ve searched. Circle to Search has quickly become one of Google’s most recognizable features, offering a simple way to look up anything on your screen with a quick gesture. Since launchi

Hollow Knight: Silksong costs $5 more than the original

After years of waiting, there's only three days left until Hollow Knight: Silksong is out in this world. We only got the September 4 release date a few weeks ago and now we have the final piece of the puzzle: price. Team Cherry, the indie studio behind the Hollow Knight series, has announced on X (formerly Twitter) that Hollow Knight: Silksong will cost $20. That's a $5 increase from 2017's original mega hit Hollow Knight game. Which, after almost a decade, isn't very surprising. We also have

These Wireless Earbuds Have a Screen, ChatGPT, and a Cute Robot Face—but They Sound Terrible

I like wireless earbuds because I love music. It’s very straightforward; music exists, and I want to listen to it, and wireless earbuds are the thing that gets me to the thing I love. Problem solved. You can’t see it, but I’m smugly dusting my hands right now like a mathematician at a chalkboard. There’s a symbiosis between the buds and me. A simplicity. A supply and demand so fundamental that in the gadget world, it feels like a law of nature. But, as much as I love wireless audio, there are s

Mamoru Hosoda’s ‘Scarlet’ Gets Bumped to 2026 in North America

Mortal Kombat II isn’t the only movie leaving 2025. Scarlet, the next film from Studio Chizu and anime director Mamoru Hosoda, is now arriving in early 2026 for North American audiences. Sony’s opted to push the film out of its initial December 12 slot. It’s still expected to release on November 21 in Japan and screen at film festivals in Venice, Toronto, and New York through their respective film festivals in early September and early October. The press release calls these festival screenings

Compositional Datalog on SQL: Relational Algebra of the Environment

I spent some time before making Datalogs that translated into SQL. https://www.philipzucker.com/tiny-sqlite-datalog/ There are advantages. SQL engines are very well engineered and commonly available. SQLite and DuckDB are a pretty great one-two punch. A new twist on how to do this occurred to me that seems very clean compared to my previous methods. Basically, the relational algebra style of SQL actually meshes with manipulating the Datalog body environments (sets of named variables bindings)

Meta reportedly allowed unauthorized celebrity AI chatbots on its services

Meta hosted several AI chatbots with the names and likenesses of celebrities without their permission, according to Reuters. The unauthorized chatbots that Reuters discovered during its investigation included Taylor Swift, Selena Gomez, Anne Hathaway and Scarlett Johansson, and they were available on Facebook, Instagram and WhatsApp. At least one of the chatbots was based on an underage celebrity and allowed the tester to generate a lifelike shirtless image of the real person. The chatbots also

Ride1Up TrailRush Electric Mountain Bike Review: Quality Components, Bargain Price

Buying a direct-to-consumer bike can be almost as big a gamble as investing in cryptocurrency. While a customer is not likely to lose their shirt investing in a new electric bike, buying a poorly made one may result in a serious crash or catch the garage on fire. For these reasons and more, it’s wise to do some research before clicking on the Add to Cart button. The highest-end legacy-brand e-MTBs retail for upwards of $14,000. So what do you get for $2,095, the price of Ride1Up’s first-ever el

Delete Tests

You should delete tests We’ve had decades of thought leadership around testing, especially coming from wholistic development philosophies like Agile, TDD, and BDD. After all that time and several supposedly superseding movements, the developers I talk to seem to have developed a folk wisdom around tests. That consensus seems to boil down to simple but mostly helpful axioms, like “include tests for your changes” and “write a new test when you fix a bug to prevent regressions”. Unfortunately, on

We Know When the iPhone 17 Will Be Announced, but When Can You Get It? Our Best Estimates

After months of tracking leaks and speculation, we now have a solid date for when the iPhone 17 will be announced. Apple sent out invitations -- once again with an enigmatic design that raises even more questions -- for its fall event, which is happening Sept. 9. Although it's entirely possible that the secretive company could pull a head-fake and not announce a new flagship iPhone lineup, that's about as likely as catching Taylor Swift riding a giraffe. But we don't know everything yet. Once t

Samsung multi-fold leak teases some of the phone’s wireless features

Samsung TL;DR New animations for Samsung’s upcoming multi-fold phone have leaked. The animations show off the phone’s design and a few of its features. The device appears to be capable of wireless charging, reverse wireless charging, and NFC payments. It’s not a secret that Samsung is working on a device that the industry popularly but misleadingly calls a “tri-fold.” Although it’s known that the device is on the way, Samsung has remained quiet on the details. But thanks to leaks, we’ve lear

Windows 11 25H2 update hits its last stop before release to the general public

Microsoft's fifth major iteration of Windows 11 is nearing its release to the general public—the Windows Insider team announced today that Windows 11 25H2 was being put into its Release Preview Channel, the final stop for most updates before they become available to everyone. That's around two months after the first Windows builds with the 25H2 label were released to the other preview channels. Putting a new yearly Windows update in the Release Preview channel is analogous to the "release to ma

Yooka-Laylee remaster comes to consoles and PC on October 9

Yooka-Replaylee, the remaster of the platformer Yooka-Laylee , will be available on October 9. It'll be playable on PC, Xbox Series X/S, PS5 and Switch 2. It's getting both a digital and physical release, and preorders for the physical versions are up right now. Speaking of physical copies, the Switch 2 version will include the full game on the cartridge and no game-key card. Nintendo has given developers the option to release cartridges that are basically empty shells, called game-key cards, t

Great Scott! ‘Back to the Future’ Is Getting a Snazzy Theatrical Re-Release

Forty years after its release, Back to the Future‘s pop-culture presence is as strong as ever thanks to theme parks, the tie-in musical, a missing-guitar mystery, and simply the enduring love for the movie itself. Starting October 31, fans can revisit the Robert Zemeckis-directed, Steven Spielberg-produced time-travel classic on the big screen. And we do mean big: this re-release is targeting premium, large-scale formats, including Dolby Cinema, 4DX, and D-Box—as well as IMAX. According to a Un

This ‘Magical’ Material That Dissolves Like Candy Is Exactly What EVs Have Been Missing

The irony of eco-friendly electric vehicles is the mountainous load of electronic waste they produce. So far, most targeted efforts to recycle EV batteries have been expensive and chemically toxic—and they haven’t stuck. That could change soon, however, thanks to a promising breakthrough from MIT. In a Nature Chemistry paper published August 28, researchers describe a new type of self-assembling material that easily dissolves in organic solvents. It works reasonably well as the electrolyte in a
