As expected, Apple has announced a mild update for the iPad family’s middle child today. The new iPad Air is a lot like the old one, but it replaces the Apple M3 chip with an M4. That M4 also comes with a less-expected upgrade: a jump from 8GB of RAM to 12GB, which should be helpful for those using iPadOS 26’s multi-window multitasking features.

The iPad Air still comes in 11-inch and 13-inch versions that start at $599 and $799, respectively; the only disappointment is that these entry-level models still come with 128GB of storage. A 256GB storage upgrade will run you $100, and 512GB (+$300) and 1TB (+$500) versions are also available. Preorders go live on March 4, and the tablet will be available on March 11.

The M4 iPad Air uses the same design as the M2 version from 2024 and the M3 version from last year. The M2 version of the Air was a gently tweaked version of the M1 iPad Air, but it was different enough not to be compatible with all the same accessories; most notably, the M2-and-later Airs use the Apple Pencil Pro accessory and aren’t compatible with the second-generation Pencil.

Japan will effectively ban the in-flight use of power banks starting in mid-April after a “recent series of alarming incidents,” reports the Asahi Shimbun. From the report: Currently, mobile batteries in Japan are classified as “spare batteries” and are prohibited in checked luggage. For carry-on bags, those exceeding 160 watt-hours are banned, while passengers are limited to two units for those over 100 watt-hours. There is no quantity limit for batteries of 100 watt-hours or less. The new rule will limit passengers to a total of two spare batteries, including power banks.

While there is no limit on the number of spare batteries below 100 watt-hours, carrying power banks exceeding 160 watt-hours will remain prohibited. Power banks will be capped at two units regardless of power capacity. Additionally, charging them on board will be prohibited, and it will be “recommended” that passengers not use them at all. As a result, domestic airlines are expected to require passengers to stop using power banks, cementing the effective ban on in-flight use.

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across each month. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. February’s list includes the revival of a forgotten battery design by Thomas Edison that could be ideal for renewable energy storage; a snap-on device to turn those boxers into “smart underwear” to measure how often we fart; and a dish of neurons playing Doom, among other highlights.

Reviving Edison’s battery design

At the onset of the 20th century, electric cars powered by lead-acid batteries outnumbered gas-powered cars. The internal combustion engine ultimately won out, in part because those batteries had a range of just 30 miles. But Thomas Edison believed a nickel-iron battery could extend that range to as much as 100 miles, while also having a long life and recharging times of seven hours. An international team of scientists has revived Edison’s concept of a nickel-iron battery and created their own version, according to a paper published in the journal Small.

Travel has a way of making phone bills unpredictable. You land, turn off airplane mode, and suddenly every map, message, or call feels expensive. This aloSIM Traveler’s Mobile Data Plan helps solve that problem, and right now you can get $150 in data credit for $69.99 on StackSocial. The appeal is simple: Instead of relying on daily roaming passes or hunting for a local SIM, you install a digital eSIM on your phone and buy data when you need it. The credit sits in your account, ready for future trips, as long as you use it within 12 months of redeeming it. The eSIM itself never expires, which makes this more flexible than a one-and-done travel SIM.

In practice, aloSIM works best for travelers who want predictable costs and don’t want to think about phone carriers once they land. Data plans start at about $4.50 for seven days, so that $150 credit can stretch across multiple trips or a long one, depending on how you travel. Coverage spans more than 200 countries and regions, including places like the U.S., France, Japan, the U.K., Mexico, and Canada. Connections run on local LTE and 5G networks, so speeds feel similar to what locals use. And setup is straightforward: You buy the voucher, check that your phone supports eSIMs, install the eSIM a day or two before your trip, and activate the plan when you arrive. Each plan also includes a temporary phone number via Hushed for the same duration, which can be useful for signups or short-term calls without sharing your real number.

That said, there are a few caveats to consider. Data packages expire based on the plan length you choose, not on how much data you use. For example, a seven-day plan ends after seven days, even if you barely touched it, and unused data doesn’t roll over unless your next trip happens within that same validity window. This is also limited to one device and new customers only. For someone taking one short trip and rarely traveling abroad, a single local SIM might still be cheaper, but for frequent travelers or anyone tired of $10–$20 per day roaming fees, the math makes sense. This deal offers control, flexibility, and fewer phone bill surprises.

Apple’s biggest iPhone announcements usually happen in September, but for the second year in a row the company is also bringing out a new iPhone in March. The new iPhone 17e is a new version of Apple’s basic no-frills iPhone, replacing last year’s iPhone 16e. The phone will be available to pre-order on March 4, and will be available on March 11 starting at $599.

The new iPhone includes an Apple A19 chip similar to the one in the more-expensive iPhone 17—both phones get six CPU cores, but the 17e only gets four GPU cores instead of five. The phone’s cellular modem is also upgraded, from the original Apple C1 to an Apple C1X capable of faster speeds. Like the A18 in the iPhone 16e, the iPhone 17e also supports Apple Intelligence, implying that it has the same 8GB of RAM as the iPhone 17. Apple says the new Ceramic Shield 2 front glass (also used in the iPhone 17) will be more durable, and that the “Apple-designed coating” on the display is three times more scratch-resistant than the coating on the iPhone 16e and better at reducing reflections and glare.

But there are two more-noticeable upgrades that help close the gap between the iPhone 17e and the regular iPhone 17: the first is support for MagSafe charging, a notable omission from the iPhone 16e. The second is an upgrade from 128GB to 256GB of storage in the base model, which makes the $599 version of the phone a more attractive deal. A 512GB version of the phone is available for $799.

Samsung’s newest feature turns your phone into your house keys. The company has created the Digital Home Key, a feature inside of the Samsung Wallet that should let you unlock any compatible smart door with your phone. The Samsung Wallet already offered digital car keys. 

“As we continue to evolve Samsung Wallet, delivering trusted mobile experiences remains at the core of our innovation,” Woncheol Chai, EVP and head of Digital Wallet Team, Mobile eXperience (MX) Business at Samsung Electronics, said in a statement. “Through close collaboration with our partners and in alignment with the Aliro standard, Digital Home Key brings the same level of security and ease Samsung Galaxy users expect from Samsung Wallet to their homes.”

Created by the Connectivity Standards Alliance (CSA), Samsung calls Aliro an “industry-standardized communication protocol.” The Digital Home Key will also get support from smart lock brands like Nuki and Schlage. It’s also designed to meet EAL6+ security certification. 

According to Samsung, you’ll also need biometrics or a PIN to use the Digital Home Key. You should be able to remotely manage or remove the tool through Samsung Find if you lose your phone.

Samsung is rolling out the Digital Home Key in select regions starting this month. It plans to expand its range as compatible smart lock brands become available in more locations.

Apple has just announced the addition of the iPhone 17e to its smartphone lineup. This model is kitted with the same A19 chip that powers the base iPhone 17, and it will support the Apple Intelligence suite of AI tools. As the rumors suggested, the iPhone 17e will indeed be priced at $599, same as last year’s iPhone 16e. The base model will come with 256GB of storage, and also be available in a new pink color.

The iPhone 16e was missing a few elements that are now being added to the 17e, most notably MagSafe charging at Qi2 speeds. This means it can charge wirelessly at 15W compared to the 7.5W.

Apple also gave the iPhone 17e its C1X cellular modem, which it said is “up to 2x faster than C1 in iPhone 16e.” This year’s entry-level iPhone also has Ceramic Shield 2 on its 6.1-inch Super Retina display, which Apple says offers “3x better scratch resistance than the previous generation and reduced glare.”

Most of the other specs appear similar to the iPhone 16e, including the 48-megapixel Fusion camera that uses one single hardware sensor to provide two dedicated camera pipelines. It’s not yet clear whether there are specific changes here, but to use Apple’s words in its press release, “[The Fusion camera] also enables an optical-quality 2x Telephoto — like having two cameras in one.”

The iPhone 17e is rated IP68 for dust and water resistance, and will also support Emergency SOS, Roadside Assistance, Messages and Find My via satellite. From the outside, the device looks very similar to its predecessor, with the same shape, notch and buttons as before. We’ll of course have to wait for a review unit and more information to know for sure, but Apple continues to state that the iPhone 17e delivers “all-day battery life,” though adding this time it’s aided by the C1X modem “and the advanced power management of iOS 26.”

Apple unveiled most of its iPhone 17 roster back in September, but its budget models usually are introduced a few months later. We’re also still waiting on the official news of what’s colloquially being calling the iPhone Fold, which is rumored to arrive in the back half of this year.

The iPhone 17e will be available for pre-order on March 4, and will start arriving in stores on March 11.

Apple is kicking off multiple days of product announcements this morning with a new iPad Air. Unsurprisingly, it’s more or less like the iPad Air Apple announced one year ago, except it now has an M4 chip instead of last year’s M3.

Apple is also including its in-house networking chips, the N1 and C1X, which will cover Wi-Fi and cellular connectivity. This means the iPad Air supports the Wi-Fi 7 standard for the first time. The Air also now has 12GB of RAM standard, up from 8GB in the prior model.

The rest of the iPad Air appears unchanged at this point. It has the same display that the 2023 and 2024 models sported — either an 11- or 13-inch LCD that tops out at 500 nits of brightness and a 60Hz refresh rate. Storage options start at 128GB and go up to 1TB, same as last year. The dual stereo speaker configuration and both front- and rear-facing cameras are unchanged, as well.

For those keeping track, it’s been less than two years since Apple redesigned the iPad Air, adding a 13-inch model that had an M2 chip. I remain surprised the company is committed to releasing chip updates for the Air so frequently — even the M2 model is more than powerful enough for the target audience. But, getting a faster chip for the same money is hard to complain about.

Naturally, the iPad Air M4 is running iPadOS 26, which was released last fall. It was, without a doubt, the biggest iPadOS update we’ve seen, bringing a far more robust multitasking system than the iPad has ever had before. It’s most noticeable and useful on the larger 13-inch screen, but having greater freedom with window management and more robust background tasks is a huge step forward — even if the Liquid Glass visual redesign is a bit divisive.

Pre-orders for the new iPad Air M4 open on Wednesday, March 4, and the tablet will be fully available on March 11. As before, pricing starts at $599 for the 11-inch model and $799 for a 13-inch display.
