Google Home may soon let you pin weather and AQI data for quick checks (APK teardown)

Rita El Khoury / Android Authority TL;DR An upcoming release of Google Home could soon support Outdoor Weather and Outdoor AQI information in the Favorites tab.

Google's Imagen 4 text-to-image model promises 'significantly improved' boring images

Google has unveiled its latest text-to-image model Imagen 4 with the usual promise of "significantly improved text rendering" over the previous version, Imagen 3. The company also introduced a new deluxe version called Imagen 4 Ultra designed to follow more precise text prompts if you're willing to pay extra. Both arrive to a paid preview in the Gemini API and for limited free testing in Google AI Studio. Google describes the main Imagen 4 model as "your go-to for most tasks" with a price of $.

Finally, a MagSafe accessory that's sturdy, highly-functional, and affordably priced

ZDNET's key takeaways The Supcase MagFlip is a magnetic wallet and stand combo for $42. It holds up to five cards, features RFID protection, and can be adjusted into several viewing configurations. While a rugged option, the cards can be difficult to access, and it's rather bulky. View now at Amazon View now at Supcase more buying choices I'm a MagSafe fan. If there's anybody at ZDNET that's tested them all (or what feels like close to it) – it's me. I've used tons of MagSafe gear from dozens

Amazon Is Selling Best Buy’s TV at a Loss, This 32″ HD Smart TV Is Now Almost Free

For an all-time low price of $69, down from $129 (46% off), you get a 32-inch smart TV with features and quality way better than what you’d typically pay for this amount.

The axion may help clean up the messy business of dark matter

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter. Although the potential for axions to explain dark matter has been around for decades, cosmologists have only recently begun to seriously search for them. Not only might they be able to resolve some issues with older hypotheses about dark matter, but they also offer a dizzying array of promising avenue

This New Watch Is Being Purpose-Built for Space Exploration—and It's Not an Omega

When you think of space exploration and watches, one name immediately comes to mind: Omega. Since its Speedmaster chronograph was selected by NASA half a century ago it has become synonymous with space travel. The timing of a 13-second engine burn to save Apollo 13 cemented its role in space history, and Omega has not missed a single opportunity to deepen the partnership, from officially naming it the Moonwatch to creating endless commemorative limited editions (even if it is by no means the onl

You’re not alone: This email from Google’s Gemini team is concerning

Edgar Cervantes / Android Authority TL;DR Google is notifying users that, starting July 7, 2025, Gemini will be able to assist with apps like Phone, Messages, and WhatsApp, regardless of whether Gemini Apps Activity is turned on or off. The vague wording in the email has raised privacy concerns, with users unclear if Gemini will still access these apps even after opting out. While the email says users can disable these features in the “App settings,” it offers no specific steps to do so. Goo

I changed 5 settings on my TV to give it an instant performance boost

Kerry Wan/ZDNET Whether you're considering buying a new TV or your old flat panel seems to be doing fine, there are still ways to optimize your viewing experience, and it all begins with your television's settings. Let's explore some of the key factors determining how your TV performs and what you can do to make it look even better. 1. Turn down the sharpness The sharper the picture, the better. Right? Not necessarily. Contrary to popular belief, the "sharpness" setting on your TV doesn't af

Managing time when time doesn't exist

The Ultimate Productivity Paradox Imagine explaining to your boss why you’re late for a meeting because time doesn’t actually exist. Not in the philosophical “time is a social construct” sense that gets you invited to fewer dinner parties, but in the rigorous scientific sense where quantum gravity’s most fundamental equations contain absolutely no time variable whatsoever. You’d be attempting to justify tardiness using cutting-edge physics to someone whose greatest temporal insight is schedulin

‘Ironheart’ Has Kinks to Work Out, But Flies High Enough

Since Avengers: Endgame, the MCU has examined which heroes will step up now that most of the original characters have bowed out. In the case of Iron Man, this question has mostly been answered in Spider-Man, but fans of the armored Avenger’s comics know his actual successor comes in Riri “Ironheart” Williams, introduced in 2016 by Brian Michael Bendis and Mike Deodato, Jr. Marvel brought Riri into the cinematic fold with 2022’s Black Panther: Wakanda Forever, with the promise of her eventually

'Ironheart' Review: Marvel Series Is Not Too Heavy, but It's Not Too Light, Either

The first time Riri Williams' solo TV show was mentioned was in 2020 when Kevin Feige announced Ironheart and Secret Invasion along with a few other Marvel Phase 5 releases. He said both series would tie in with Marvel's feature films. It's true: Ironheart is connected to the larger MCU -- aside from Black Panther: Wakanda Forever -- and for that reason alone, you should watch all six episodes of the series to the end. All the way to the very end. Ironheart is streaming its first three episodes

Ironheart believes the children are the future

Before the multiverse, magic, or any of Marvel’s streaming series were important parts of the studio’s cinematic universe, there was Iron Man. After years of so-so movies, Iron Man reminded everyone that Marvel’s big-screen adaptations could be amazing with the right creative teams and stars attached. Robert Downey Jr.‘s Tony Stark was the MCU’s centerpiece and a prime example of how the House of Ideas could make box office record-breaking icons out of its lower-profile characters. A couple of t

'Fast tech' warning as demand for cheap gadgets heats up

'Fast tech' warning as demand for cheap gadgets heats up 59 minutes ago Share Save Chris Vallance Senior Technology Reporter Share Save Getty Images Demand for so-called "fast tech" - cheap electronic items often quickly binned or abandoned in drawers - is growing, a not-for-profit that works to reduce electronic waste has warned.

The Jumping Frenchmen of Maine

In the late 19th century, a rare and highly unusual neuropsychiatric condition was observed among a group of French-Canadian lumberjacks living in the Moosehead Lake region of northern Maine. Those affected exhibited an extreme and exaggerated startle reflex. When startled by a sudden movement or loud noise, they reacted with dramatic involuntary responses, such as leaping into the air, screaming, repeating words, or instantly obeying shouted commands. It was reported that the "jumpers" were pri

Best Portable Air Conditioners: Cooling Your Home One Room at a Time

Not only did the Midea MAP14HS1TBL excel in performance compared with most portable air conditioners we tested, but it also has a lot of features and specialty options. This model isn't cheap, but it's a well-rounded luxury AC unit with everything you need -- and then some. To start, the MAP14HS1TBL has the highest cooling capacity of any other model we tested. Those 12,000 BTUs come in handy for cooling larger spaces up to 550 square feet, and it showed in the performance. The Midea model beat

Bitcoin price rises as Israel-Iran ceasefire begins, and Senate unveils major crypto bill

Crypto prices, including bitcoin , rose on Tuesday after President Trump announced a ceasefire between Iran and Israel. By midday Tuesday, bitcoin had passed the $105,000 level, ether jumped back above the $2,400 mark, and XRP climbed to $2.19. The risk-on action in the markets, which also saw stocks rally on the Mideast de-escalation, wasn't the only source of momentum, as Republican senators unveiled a major bill to set the rules of the road for crypto. Specifically, the legislation would de

Google rolls out text-to-image model Imagen 4 for free

Google Imagen 4, which is the company's state-of-the-art text-to-image model, is rolling out for free, but only on AI Studio. In a blog post, Google announced the rollout of the new Imagen 4 model, but reminded users that it's free for a "limited time" only. Unlike the old text-to-image model, Imagen 4 offers significant improvements and takes the text-to-image generation quality to the next level. Comic generated using Imagen 4 Google says it has two new Imagen models. The first one is cal

‘Witcher’ Author Understands Why George R.R. Martin Is Taking So Long on ‘Winds of Winter’

It’s been over a decade since the last Witcher book was released—2013’s Season of Storms, which got an English translation in 2018—but there’s a new title coming very soon from Andrzej Sapkowski: September’s Crossroads of Ravens. In between books, Netflix launched its hit Witcher series, which still has a fourth and fifth season yet to share. That puts Sapkowski on a different sort of timeline from another author whose fans have been waiting awhile for a new book to arrive in his adapted-for-TV

If You Own an iPhone, Amazon Is Offering a Free AirTag Before Prime Day

Apple doesn’t often discount products, and AirTags have never been on sale from the Apple website or in Apple stores. Amazon, however, occasionally surprises us with exclusive pricing on these useful Bluetooth trackers. For the best value, a pack of AirTags is nearly always a better buy than a single one. Amazon is also running a great deal just in time for Prime Day: purchase three AirTags and receive a fourth free. That drops the price of four AirTags to just $74, down from the regular $99 ($

Doug Liman Will Attempt to Cram Stephen King’s Epic Novel ‘The Stand’ Into a Single Movie

The world already feels like it’s on the brink of doomsday, so we might as well gear up for another round of Captain Trips. The Stand, Stephen King’s doorstop-sized 1978 post-apocalyptic novel, is getting a new adaptation from director Doug Liman—with a twist. Instead of another series following in the footsteps of the 1994 and 2020 versions, this will be instead be a feature film. This news comes from the Hollywood Reporter, which notes that Liman is aboard to direct and produce, but “the proj

This Star Wars Galactic Map Clears Up Confusion About a Galaxy Far, Far Away

Have you ever wondered about the distance between Tatooine and Naboo? How about Obi-Wan Kenobi's accumulated mileage during the Clone Wars? The good news is that the force is with you: All of your questions are answered by the new Star Wars Galactic Map. The map divvies up the Star Wars galaxy into important regions. Movie fans might be familiar with the core worlds (where Coruscant is) and the outer rim (where you can find Tatooine), but the deep core, colony worlds, inner rim, expansion regio

People Are Already Dropping Dead as Extreme Heat Scorches the US

In large swaths of these United States, people are already dying from this summer's brutal heat wave. According to St. Louis' KMOV, a 55-year-old woman was found dead in her apartment this week after her electricity had been shut off during this so-called "heat dome" phenomenon — which involves heat being trapped by atmospheric conditions, as if by a lid or a cap. Reporting from KSDK, another area broadcaster, indicated that the woman had been stranded in her apartment without air conditioning

An intelligent, practical path to reindustrialization

Then, a little over a decade ago, MIT’s “Production in the Innovation Economy” initiative highlighted the opportunities we miss if design and manufacturing teams are miles or even oceans apart—and played a significant role in shaping the nation’s Advanced Manufacturing Initiative. Building on this legacy, and in response to an urgent national interest in restoring America’s manufacturing strength, an inspired group of MIT faculty came together in 2022 to found the Manufacturing@MIT Working Grou
