Tiny cameras in your ears may be part of Apple’s AI future. The company is preparing camera-equipped AirPods for release in late 2027, according to a report from Bloomberg’s Mark Gurman on Tuesday. 

The new earbuds are expected to arrive around the same time as a second-generation foldable iPhone and a 20th-anniversary iPhone model, Bloomberg reported, citing unnamed people familiar with Apple’s plans. Apple didn’t immediately respond to a request for comment.

The cameras reportedly wouldn’t be meant for taking photos or recording video of the inside of your ear. Instead, they would act more like AI sensors, giving Siri visual context about the world around you.

That could let someone ask Siri questions about what they’re looking at, like what to make for dinner based on a set of ingredients, according to Bloomberg. This would most likely use Apple’s Visual Intelligence feature, which is designed to analyze images and provide context based on what the camera on your device sees.

Apple announced new Siri and Visual Intelligence features last week at WWDC 2026 as part of iOS 27 and its other operating system updates. The new Apple Intelligence features are expected to arrive this fall, while Siri AI will be available as a beta later this year.

Bloomberg reported that the camera AirPods are code-named B798 and were originally planned for 2026 but were slightly delayed due to Apple’s struggles with AI software. The company also reportedly needed more time to develop visual AI models capable of identifying objects in its surroundings.

The earbuds are expected to look similar to current AirPods Pro models, aside from cameras embedded in the stems. Bloomberg also reported that the device would include external lights to show when data is being sent to the cloud for processing.

The reported AI-powered AirPods are part of Apple’s broader push into AI hardware. Bloomberg said Apple is also working on smart glasses that could arrive as early as late 2027, along with a camera-equipped pendant that could be worn on clothing or around the neck.

Apple is reportedly preparing a busy iPhone lineup. Bloomberg previously reported that Apple’s first foldable iPhone is expected to launch in 2026. Apple is also said to be working on a 20th-anniversary iPhone with a nearly edge-to-edge display and curved glass that wraps around the sides.

The timing could still change, as it has in the past. Apple hasn’t announced camera-equipped AirPods, a foldable iPhone or a 20th-anniversary iPhone.

Let’s stop for a moment and pause to consider the smart bulb. Imagine going back 20 years and telling yourself that people will be putting computers capable of acting as web servers into light bulbs just so they can control them from their telephone instead of hitting the switch. The whole thing seems crazy — but its great, because it enables hacks like this one where [RickOOOOOO] takes a commercially-available ESP32 smart bulb, and hacks it into a local file server and digital library for banned books.

The word “banned” gets bandied about a lot — but assured, there’s nothing getting served up by [RickOOOOOO]’s bulb that’s going to help somebody will ill-intent build an improvised explosive device.  No, at least as conceived here, it appears to be full of easily-available e-books that were pulled from school libraries in the USA, which may-or-may not meet your personal definition of ‘banned’. Whatever you want to call them, we appreciate the idea that a student could hypothetically replace one of the bulbs at school with a hacked version serving up that sort of content. a bulb in such a school with a bulb hacked to host that sort of content–in minecraft, naturally.

In any case, the hardest part of the hack was carving the ESP32C3 in the bulb out of the IoToreo bulb enough to access it. Unfortunately having done so, [Rick] wasn’t able to get an SDcard interface soldered on, so he’s stuck with just 4MB for books and webserver. That means only a few epubs can fit on the bulb, but it’s better than those books being unavailable.

Like the solarpunk message board we featured recently, which also ran on an ESP32, the bulb broadcasts a public network that uses a captive portal to take you to the web interface of the library. From there, users can browse books– including learning from where they were banned and why–and admins can access a password-protected control panel. One neat work-in-progress feature on the control panel is that the bulb can still be used as a smart bulb, so you can try and match the light to its surroundings. In Minecraft, because of course we would never encourage kids to change light bulbs. Perish the thought!

Speaking of Minecraft, you can run a server on a lightbulb, too. Or DOOM, because of course even the light bulbs run DOOM now. What a time to be alive!

But will it see the same success as the MacBook Neo?

Apple‘s first foldable iPhone is still expected to debut later this year, but the company may already be looking beyond its first attempt. According to Bloomberg’s Mark Gurman, Apple is planning a second-generation foldable iPhone for release in 2027, just one year after the original model is expected to arrive. The device is reportedly codenamed V78 and will launch alongside the 20th-anniversary iPhone model. It looks like Apple might be going all in on foldables as a long-term product category rather than a one-off experiment.

The Cupertino giant has spent years watching rival smartphone makers refine foldable hardware. Samsung, Google, Honor, Oppo, and others have gone through multiple generations of designs, experimenting with everything from narrow book-style devices to wider tablet-like formats. Apple appears to have waited until the category matured before making its move.

Apple may have learned from Android’s foldable experiments

Based on leaks and replica models that have surfaced in recent months, Apple’s foldable iPhone is expected to use a relatively short and wide design rather than the tall, narrow form factor seen on earlier Samsung Galaxy Z Fold devices. The device is rumored to feature a 5.5-inch cover display and a 7.8-inch inner panel with a 4:3 screen format.

That layout mirrors much of Apple’s iPad lineup and could provide a more natural and familiar experience for multitasking, reading, and running apps side by side. At 7.8 inches, the inner display would also come close to the iPad mini‘s 8.3-inch screen, potentially giving users a tablet-like experience when the device is unfolded. Apple appears to be preparing the software side as well, encouraging developers to ensure their apps adapt smoothly to different screen sizes and display formats.

Even Samsung appears to be moving in the same direction

Interestingly, Samsung may be arriving at a similar conclusion. Rumors suggest the company is preparing a wider foldable design for next year’s lineup, with the Galaxy Z Fold 8 Wide potentially becoming the standard Galaxy Z Fold 8. A taller version could reportedly be positioned as the Galaxy Z Fold 8 Ultra instead.

Whether Apple’s foldable strategy pays off remains to be seen, but the company does not appear to be treating the device as a one-year experiment. A second-generation model already in development suggests Apple expects the iPhone Ultra to establish itself as a permanent tier within the iPhone lineup, with enough demand to support regular annual updates.

Monitor Audio has launched the Radius Series 4G, a redesigned compact speaker range aimed at listeners and installers who need serious sound without large cabinets taking over the room.

The new lineup includes the Radius 1, Radius 3, and Radius On-Wall, supported by matching floor stands, desk pads, and wall bracket options. That gives the Radius Series 4G a broader role than a typical small speaker refresh. It can be configured for two-channel listening, desktop audio, multi-room systems, home theater, and commercial installations where space, appearance, and mounting flexibility matter almost as much as sound quality.

Monitor Audio is positioning Radius Series 4G around its Transparent Design Philosophy, but the bigger story is practical: compact loudspeakers that are designed to look finished in modern residential and commercial spaces, while still being flexible enough for stereo, surround, and near-field applications. Small speakers are often treated like compromise products. Radius 4G looks more like Monitor Audio trying to make the category useful again.

Compact Speakers, Smarter Engineering

The Radius Series 4G is still a compact speaker range, but Monitor Audio has put meaningful engineering into this generation rather than simply updating the cabinets and calling it a day.

The core driver technology remains Monitor Audio’s C-CAM cone material, which uses a ceramic-coated aluminium/magnesium structure designed to be light, rigid, and resistant to unwanted flexing. For Radius 4G, that driver platform now incorporates RST III cone geometry, a surface pattern developed to reduce breakup and resonance across the frequency range. In a small speaker, that matters. There is only so much cabinet volume to work with, so driver control becomes a much bigger part of the performance equation.

The tweeter has also been redesigned. Radius Series 4G uses a new C-CAM Gold Dome tweeter with an external magnet motor system, bringing it closer in concept to a full drive unit rather than relying on a more conventional internal puck magnet design. Monitor Audio says the goal is greater control and cleaner high-frequency performance, which should help the Radius models sound more open without becoming bright or thin.

The crossover networks have also been reworked with new measurement, listening, and component selection. That is not the flashiest part of the story, but it is often where compact speakers either come together or fall apart. Good drivers still need to be integrated properly, especially when the speaker is being used for desktop listening, wall-mounted applications, or home cinema channels.

Cabinet construction has received attention as well. Monitor Audio uses Through-Bolt Driver Bracing to lock the drive units to the rear of the cabinet at a specific torque, improving rigidity while reducing unwanted chassis resonance. Each model also includes Monitor Audio’s HiVe II port design, created to improve airflow and bass control. On the new Radius 3, the port is 50 percent larger than the previous generation, which should help it deliver more low-frequency output from a still-compact enclosure.

The accessory range is also part of the story. The Radius 4G Floor Stand uses wooden tripod legs with internal cable routing, giving the speaker a more furniture-friendly presence. The Desk Pad is made from vibration-isolating rubber and gives the speaker a slight upward tilt for near-field listening. Add in the wall bracket options, and Radius 4G starts to look less like a single-use compact speaker and more like a flexible system for stereo, desktop, surround, multi-room, and commercial installation use.

The Bottom Line

The Monitor Audio Radius Series 4G is not trying to replace a full-size hi-fi speaker system, and that is the point. Its appeal is the combination of compact cabinets, real Monitor Audio driver technology, flexible mounting options, and a cleaner design language that works in rooms where traditional speakers are either too large or too visually intrusive.

What makes Radius 4G different is the range of applications. Radius 1 4G can handle discreet surround, desktop, and multi-room duties; Radius 3 4G is the more capable compact stereo, TV, gaming, and near-field option; and Radius On-Wall 4G gives installers and home theater users a slim horizontal or vertical speaker for screen-based systems. Add the dedicated floor stands, desk pads, and wall brackets, and this becomes less of a small speaker refresh and more of a flexible compact audio system.

This is for apartment dwellers, design-conscious listeners, desktop users, custom installers, and anyone building a living room, media room, retail, hospitality, or office system where sound quality matters but big boxes are a non-starter. Bass obsessives and large-room listeners will still want a subwoofer, but for modern spaces that demand compact speakers with legitimate hi-fi intent, Radius 4G makes a lot of sense.

Elementary school is tough.

There are playground politics, multiplication tables and learning to read.

Imagine dealing with all that in a new language — or even a whole new country.

That’s the added challenge for kids who are learning English at the same time they’re learning everything else as their peers.

It’s an issue that Sarah Walters and her colleagues were determined to tackle in Troy City Schools, a public school district made up of nine campuses roughly an hour north of Cincinnati. The area is home to an automotive manufacturer that brings some employees — and their families — over from Japan.

Roughly 3 percent of the 4,000 students have primary languages like Spanish, Ukrainian and Japanese, a relatively small population compared to the most recent national average of 11 percent.

But that small group is making big gains. Looking to close the literacy gaps that have plagued schools since the pandemic, the district took a big swing to increase literacy among its English learners. It trained 116 staff members — including every elementary teacher, intervention specialist, paraprofessional and principal — in the Orton-Gillingham approach, which folds movement and touch into reading instruction.

They say it’s paying off.

Walters, a literacy instructional support specialist, says that helping multilingual students master their grasp on English is vital. Like any other student, the foundation that they lay in reading and math will affect their learning from that point on.

“We want to help the students continue to thrive, and really everything that we’re thinking about with our student services is equitable learning opportunities,” Walters says.

Moving Toward Equity

Federal data shows that English learners’ achievement scores lag far behind their peers on average, and have made little improvement over the past two decades.

Troy City Schools was eager to close widening literacy gaps that surfaced after the onset of the pandemic, Walters says, which was particularly hard on English learners like those at Concord Elementary. A big hurdle was phonics, the letter sounds that make up words.

“We were seeing a lot of student frustration and wanting to give up,” Walters recalls. “Students being very withdrawn, those social-emotional impacts.”

Back in 2020, English-language instruction was inconsistent and fragmented across classrooms.

Yet, even with the desire to boost English learner scores, the program took some time.

Following the pandemic, Troy City Schools mulled over the changes for three years before it had enough funding to deliver on it, according to Danielle Romine, director of elementary teaching and learning for the district. The effort was funded through post-COVID relief grants and budget allocations made by the district’s leaders.

As a literacy specialist, Walters became certified in the Orton-Gillingham method through the Institute for Multi-Sensory Education. She’s now responsible for supporting and training staff to successfully use the techniques.

Walters says teachers and staff were trained to utilize drills that connect literacy concepts through visuals, sound and movement. Students might use flash cards as a visual element or tap their fingers to each letter as they spell out a word. Students also learn the origin and history of words to strengthen their ability to decode them. For example, a “red word” is one that does not follow phonics rules.

“Our multilingual learners love it because no longer are they being told, ‘That’s just the way it is,’” Walters says.

After an initial summer training on the Orton-Gillingham approach, teachers spoke so highly of the method that requests for training grew among staff.

Initial Promise

“In a school district, if you want to get something out, just tell a teacher, because it [will] spread like wildfire,” Romine says.

And the data are showing promising results, Walter says. The district-wide third grade reading proficiency had plummeted to 56 percent in 2021-22 but had risen to 81 percent by 2023-24 — slightly higher than its pre-COVID achievement rate. The most recent state data shows Concord Elementary far surpassed its target goal for English proficiency among multilingual students.

Walters has heard from teachers who say that the approach has helped some English learner students make lightning-fast gains in reading. One educator told her that two students from Japan who joined the elementary school in the fall were conversing in English by December. Another student’s phonics diagnostic score shot up by 38 points in the same timeframe.

Now, the district is working to spread the method beyond its own campuses.

“Eventually, our goal is to support the entire community, or the entire county because Sarah having that training [enables her] to support teachers from other districts, as well,” Romine says.

But for English learners, ensuring they’re on grade level in reading goes beyond measuring their success in the classroom.

Walters says that the district is thinking about long-term learning for children who, for example, may be in the U.S. for a few years before returning to Japan.

“We want students to have success across math, science, everything,” Walters says. “So it’s important that we get them up to speed as quickly as possible, because those long-term impacts could really be harmful for them. That early literacy is key.”

Running low on memory, can’t afford more? The House of Zen’s latest acquisition puts an AI spin on flash-based memory expansion

With no end in sight to the memory crunch, AMD thinks that AI, the main cause of the shortage, could be part of the solution. This week, the House of Zen acquired predictive memory startup Mext for an undisclosed sum, setting the stage for a world where bots decide which data to put into RAM and which to store in less-expensive flash.

Founded in 2023, the Mext proactive memory platform uses machine learning algorithms and learned heuristics to proactively offload “cold” memory to flash storage, and, based on data access patterns, restore it before its needed again.

Modern flash arrays are already approaching main memory in terms of aggregate bandwidth, but swapping to disk still imposes a stiff latency penalty.

Mext claims it can expand the effective memory of a system by 2 to 4x using flash, which gig for gig is still vastly less expensive than DRAM.

This flash memory is exposed to the operating system like regular memory simply by running the Mextd daemon.

Memory tiering is nothing new and has seen various reincarnations over the years with some being software based and others, like Intel Optane persistent memory, using special 3D XPoint memory tech co-developed by Micron.

Mext stands out for its use of machine learning to migrate data from hot memory to cold storage almost like a branch predictor — something AMD has an awful lot of experience with.

Mext isn’t using one model to decide when to shuffle your data. Instead it uses a series of heuristics, long short term memory, and modern transformer architectures depending on which combination renders the best results.

“This approach has the potential to reduce infrastructure costs, improve resource utilization, and help customers more effectively scale general-purpose and AI workloads,” Dan McNamara SVP of AMD’s compute and enterprise AI biz wrote in a blog post this week.

Beyond enterprise applications, the technology could have implications for AI serving.

Modern mixture of experts (MoE) models are, as their name suggests, comprised of multiple sub-models.

For each token predicted, a different selection of experts may be used. In practice an LLM may use some experts more frequently and others rarely.

We wouldn’t be surprised to see AMD use Mext’s prediction algorithms to offload infrequently utilized experts from HBM to slower system memory, enabling enterprises to take advantage of larger more capable models with fewer resources.

That’s just speculation of course, but we’ve reached out to AMD for comment; we’ll let you know if we hear anything back. ®

After multiple delays, Shrek is back, and he is bringing the whole family time! DreamWorks has released the first trailer for Shrek 5, and it is exactly as chaotic as you would hope. The film marks the franchise’s return after 17 years since Shrek Forever After in 2010, and it hits theaters on June 30, 2027.

The wild moments in the Shrek 5 trailer

Mike Myers, Eddie Murphy, and Cameron Diaz are all back as Shrek, Donkey, and Fiona. The trailer opens with a storybook recap of the original story, before Donkey interrupts to announce it is time for a makeover.

The gang, now joined by Shrek and Fiona’s three grown-up kids, head to a new city called Further Further Away, which is sketchier than Far, Far Away ever was.

The trailer wastes no time in serving up a Gingerbread Man with two gumdrops strapped to his butt, proudly declaring he is “caked up like a friggin’ bakery,” followed by some very enthusiastic twerking.

There is also a melting, grimy snowman lurking in a back alley asking, “Wanna date a snowman?” taking a dig at Frozen’s Olaf.

Where is Zendaya’s character Felicia in the Shrek 5 trailer?

Zendaya voices Felicia, Shrek and Fiona’s daughter, and her involvement in Shrek 5 has been confirmed. However, she is completely absent from the trailer footage. Shrek can be seen in the jail cell with Fiona and his two sons, Fergus and Farkle, but Felicia is nowhere to be found. Whether Felicia got kidnapped or simply had better weekend plans is anyone’s guess.

Why are fans upset about the Shrek 5 trailer?

Not everyone is thrilled with how the trailer looks, though. Many fans have taken issue with the updated animation style, which makes Shrek and Donkey look noticeably more detailed and lifelike than in the previous films.

its actually insane that a movie from 15+ years ago has infinitely better lighting, skin textures than movie coming out in 2027. how did technology regress this badly?? they need to throw out the new assets and bring back the classics. #fixourshrek #shrekisnotminions #notmyshrek

Comments on Universal’s Instagram ranged from “we want the old Shrek back” to “do what they did with Sonic,” a reference to how Paramount famously redesigned Sonic the Hedgehog after fans revolted over his original movie look. It’s too early to say if Universal would be forced to do the same.

If animated trailers are your thing right now, Pixar also just dropped the first trailer for Gatto, and Disney unveiled its first look at Hexed, the studio’s most exciting original film in years.

On Wednesday morning, workers poured hydrogen peroxide into the Lincoln Memorial Reflecting Pool in Washington, DC.

The treatment is the latest attempt by the Interior Department to control an algae bloom that has turned the pool bright green, despite President Donald Trump’s costly renovation to make it “American flag blue” in time for the nation’s 250th anniversary. Hot temperatures and climate change are among the risk factors that could be driving the outbreak.

The Trump administration spent more than $14 million to update the pool ahead of celebrations across the US capital. The work was done under a no-bid contract by a company that has never worked for the federal government. (It has, however, worked on President Donald Trump’s golf courses, according to The New York Times.)

Algae began forming less than a day after the updated pool was unveiled last week. An Interior Department spokesperson told CNN that the bloom was due to “residual algae from the supply lines, which have been sitting dormant for eight weeks.”

One of the issues appears to be the water source. The Reflecting Pool usually draws water from the nearby Tidal Basin, which is often filled with algae. During periods with high amounts of algae, the water supply switches to municipal drinking water. The US Interior Department didn’t immediately respond to questions from WIRED about which water source is currently feeding the pool.

Another issue is the weather. High temperatures create “a perfect storm for [algae] to bloom,” says Hans Paerl, a former professor at the University of North Carolina’s Institute of Marine Sciences. Stagnant water, Pearl says, makes the problem even worse. “Lakes and reservoirs around the world—they all have this problem during this time of year.” Hotter-than-normal weather is expected to hit Washington, DC, to end the week, which could make controlling the bloom more challenging.

Paerl also points out another, related driver that the Trump administration has shown it’s not in a rush to resolve: climate change.

“It’s just getting hotter, and these blooms are expanding globally—they’re moving up into higher latitudes,” he says. “It’s clearly a temperature effect allowing them to optimize their growth.”

Beyond the hydrogen peroxide, the Interior Department is “deploying high-tech nanobubble ozone technology” to keep algae at bay, an agency spokesperson tells WIRED in an email.

Trump has touted the work on the pool, which includes painting it blue and fixing leaks, while also saying the company the government hired would be able to do repairs “in much less time, for much less money.”
