Japanese researchers at Yokohama National University (YNU) developed a breakthrough manganese-based battery for electric vehicles (EVs), achieving an energy density of 820 watt-hours per kilogram (Wh/kg). This surpasses the performance of current nickel and cobalt (NiCo) batteries, which reach 750 Wh/kg, while lithium-based batteries deliver only 500 Wh/kg.
The team’s work offers a more sustainable and cost-effective alternative to NiCo batteries, whose scarcity and high cost pose challenges as EV adoption grows globally.
The researchers focused on using manganese in the battery anode, specifically employing LiMnO2 (lithium manganese dioxide) as the material. Traditional challenges with manganese, such as poor electrode performance and voltage decay, were mitigated by utilizing a monoclinic system, a specific crystalline structure.
This system facilitates a phase transition to a spinel-like phase, significantly improving battery performance. By synthesizing nanostructured LiMnO2 with a high surface area, the team achieved large reversible capacity and excellent charge rate capability, making it suitable for EV applications.
One major advancement is the absence of voltage decay in this manganese-based battery, a problem that previously affected performance in earlier manganese applications. While the possibility of manganese dissolution remains, the researchers aim to address this with a highly concentrated electrolyte solution and lithium phosphate coating.
This innovation provides a competitive and environmentally friendly alternative to existing EV battery technologies. The simplicity and low cost of the synthesis method further enhance its potential for commercialization. The findings, published in ACS Central Science, highlight the team’s contribution to advancing sustainable EV battery technology with promising implications for the future of electric mobility.

Apple announced a bunch of new products at the It’s Glowtime event on Sept. 9, but the rumored Apple Watch SE with a plastic shell wasn’t among them. That doesn’t necessarily mean we won’t see it at some point, though. According to Bloomberg’s Mark Gurman, who first reported that the company was developing an even cheaper version of the budget watch, the plastic SE “is still moving forward.” Sources told Gurman it could arrive next year.
The Apple Watch SE last got a refresh in 2022 with the release of the second generation line. In addition to a plastic shell, plans for the rumored upcoming watch include bolder colors that would appeal to kids, Gurman reported. But, Apple has apparently hit a manufacturing snag with the plastic design. Last Monday’s official Apple Watch news focused on the Series 10, which has a thinner build and larger display, as was expected in the leadup to the event. In a hands-on with the new wearable, Engadget’s Billy Steele called the Series 10’s brighter, wide-angle OLED display “a massive upgrade” compared to other recent models.

Every couple of years, a core childhood memory resurfaces and sends me hunting for a bizarre PlayStation game my brother and I obsessed over but never actually played in its entirety. The internet search goes like this: game on red-and-black PS1 demo disk featuring feral child with pink hair tackling pigs and trees that look like butts. The results tell me the game I’m looking for is the 1997 platformer Tomba!, and I giddily bask in the nostalgia. Then I forget all about it, and the cycle eventually repeats.
You can imagine my surprise, then, when a trailer popped up earlier this summer announcing Limited Run Games’ rerelease of Tomba! in all its wacky glory for modern consoles. Tomba! Special Edition is now available digitally for PS5, Nintendo Switch and PC. Physical editions, a line of plushies and a themed NEO S controller (pre-orders for which are sadly sold out) are also on the way. And in finally playing it all the way through almost 20 years after its original release, I’ve discovered that Tomba! is even more unhinged than I remembered.
Tomba, the player-character, is a wild boy who lives outside of society, hunting boars and sleeping under the stars. His peace is disrupted one day when a group of delinquent pigs swoops in and wreaks havoc, ultimately robbing him of a gold bracelet that belonged to his grandfather. To get it back, Tomba ventures into the nearby towns to find the Evil Pig ringleaders and take them down. Along the way, he meets a slew of strange characters who will help guide him on his mission, but only after he completes a bunch of tasks for them.
It’s a 2.5D platformer, meaning much of the game operates like a two-dimensional side-scroller, but you can occasionally move into the background or foreground to explore the map in more depth. Tomba! Special Edition doesn’t change much about the original game. The graphics are still distinctly PS1 polygonal, and the controls can feel clunky. There are some quality of life additions, though — namely a rewind feature that ends up being extremely handy because, as it turns out, this game is pretty tricky in some spots. I found myself needing to try certain maneuvers over and over again to get them right.
Just about every part of the story and its environment carries a touch of absurdity. Tomba is able to scale walls, swing on branches, jump with inhuman ability and apparently store items (including living creatures) in his stomach, which he can regurgitate when they’re needed later on. There are the butt trees, as mentioned earlier, which are allegedly meant to depict peaches but when Tomba jumps onto them and squeezes, a cloud of magical gas comes pouring out. You’ll encounter a village of dwarves, but can only communicate with them after leaping on the heads of several dwarves to learn their language. In another village, everyone’s been turned into mice, and for some reason, they’re all wound up about the disappearance of an actual, never-been-human baby mouse.
Limited Run Games
One of the most memorable areas is undoubtedly the Mushroom Forest, a bad trip of a location that’s filled with creepy, clownish anthropomorphic flowers and mushrooms that inflict Tomba with certain ailments if he jumps onto them. One will have him laughing uncontrollably, while the other makes him wail — and that cry is deeply unsettling. It kind of jump-scared me the first time it happened, if I’m being real. With both mushroom illnesses, Tomba becomes unable to wield his weapons, instead flailing his arms and screaming if you try to do an attack.
It is altogether a surprisingly complex game, and visually striking thanks to its loud color palette. But the quest can feel convoluted as you try to navigate the often confusing map layout and fulfill the many, many tasks thrown your way. Boss fights are uniquely frustrating, too. Instead of simply beating up or killing the Evil Pigs, you have to wrangle each one and throw it in a bag… but the bag is floating and, in most cases, spinning.
While frequently maddening, Tomba! was a joy to revisit. It’s consistently silly, and the soundtrack gave me a welcome blast of nostalgia from the moment its steel drums started playing. (Tomba! Special Edition includes both the original soundtrack and a remastered version, and they’re both great.) If anything, the Special Edition release has made it clear why Tomba! has lingered so long in my memory — I can’t say I’ve ever played another game quite like it.

The Polaris Dawn crew safely returned to Earth early Sunday morning, bringing the historic privately funded mission to a close. The Dragon capsule carrying the mission’s four astronauts — Jared Isaacman, Scott “Kidd” Poteet, Sarah Gillis and Anna Menon — splashed down in the Gulf of Mexico around 3:30AM ET.
On Thursday, Isaacman and Gillis completed the first commercial spacewalk, each taking a turn to exit the craft and perform a series of spacesuit mobility tests. And with this mission, Gillis and Menon have now traveled farther from Earth than any women before. Polaris reached a peak altitude of about 870 miles, which is also the farthest any humans have ventured since the Apollo program.
The crew also performed a number of science experiments, and was able to complete a 40-minute video call to Earth and send files in a major test for Starlink’s space communications capabilities. That included a video recorded during the mission of Gillis, an engineer and violinist, playing the violin in space. “A new era of commercial spaceflight dawns, with much more to come,” Polaris posted on X Sunday morning.

Apple’s high-end earbuds will be able to be used a full-on hearing aids.
Apple
Could Apple really be teeing up a change that could save my elderly mother more than $1,500? That’s the promise of the company’s newly announced initiative to add true hearing aid functionality to the AirPods Pro — and why, with all due respect to the iPhone 16 and its fancy Camera Control button, it was the most promising section of Monday’s keynote, to my eyes.
The news couldn’t have come at a better time for me. My 80-year-old mother has finally admitted that her hearing is, shall we say, subpar. And she just asked me to book her an appointment at the Miracle Ear clinic down the street (“They’re having a fall sale!”). But before I went down that road, I decided to do some research.
The frustrating world of hearing aids
I knew that there was a burgeoning market for hearing aids since the US government opened the field to over-the-counter competition in 2022. But a bit of googling confirmed that those models — even those with familiar names, like Jabra, Sony and Sennheiser — start at $300 and go north from there, sometimes topping $2,000. And while that’s certainly a lot, the crazy thing is that it’s downright cheap compared to clinical hearing aids. Those often start at $1,000, and can go as high as $5,000 or more. Yes, really.
Some medical insurance may defer costs, but Medicare doesn’t. While retired military personnel can get hearing aids through the VA, I remember my father’s journey down that path meant that his hearing aids arrived many months after the initial hearing exam.
Jabra Enhance’s OTC hearing aid options top out at almost $2,000.
Jabra Enhance
And here’s the clincher: Many elderly folks seem to loathe their hearing aids, and for good reason: They’re generally tedious and unintuitive to use, sometimes with a single microscopic button to control volume. Want to turn them off? Pop open the battery cover, for starters. (And many hearing aids still use disposable microbatteries.) Case in point: My mother got one of these expensive pair of hearing aids years ago, but found the challenge of wearing and maintaining them wasn’t worth the so-so audio improvement they offered. They still power on, but they don’t seem to work effectively any more — and being out of warranty, the cause of our current hearing aid search.
The competition from the OTC market has helped in that regard, as the Jabras and Sennheisers of the world push the traditional hearing aid providers to become a bit more tech-savvy. Some eschew the behind-the-ear battery pack and go for earbud-style simplicity. Bluetooth connectivity for calls and apps for sound adjustments are finally more common, as older people become accustomed to using their phones and tablets.
But why go for what’s essentially an AirPods knockoff when you can get the real thing at a fraction of the price? (And — amazingly, in an age where everything has gone the subscription route — free of any sort of recurring monthly fees.)
Waiting for the software update — and managing expectations
So, when will the hearing aid features become available? What seemed to be weeks away may now be much closer. FDA regulatory signoff (in the US) is already a done deal, arriving just a few days after the initial announcement. That leaves the requisite software upgrade. You’ll need an AirPods Pro paired with a compatible device running iOS 18, or the equivalent 2024 OS updates for iPad or Mac. On the iPhone side, that’s pretty much every model sold after the 2018 model year (iPhone XS/XR and later). While those initial software updates hit on September 16, it’s unclear if the hearing aid functionality will arrive then, or sometime later — perhaps alongside the first Apple Intelligence coming in October. (Apple’s site simply says “coming this fall.”)
In the meantime, I’ve started the upsell to my mother. I showed her the relevant portion of Apple’s video presentation, and I had her try out my AirPods Pro, just to gauge fit and comfort. The initial response wasn’t enthusiastic. While she liked that they “didn’t fall out of my ears” like the AirPods 2, she’s put off by the penetration of the eartips into her ear canal. Countless other headphone fans agree, and that’s why the design of the new AirPods 4 is more open. But Apple hasn’t suggested the hearing aid functionality is coming to those headphones anytime soon — if ever.
Unlike traditional hearing aids, AirPods Pro are anything but discreet. (This shot is from Apple’s keynote video.)
Apple
And let’s be honest: This isn’t envisioned as a miracle cure. Apple specifically says this feature is “intended for people with perceived mild to moderate hearing loss.” I wouldn’t be surprised if my mother has graduated to the need for pro-level hearing assistance at this point, over-the-counter or otherwise. So we may end up opting for one of those Jabra Enhance models, which offer a 100-day no-hassle return policy.
But now we have the AirPods Pro as a testable alternative. Going forward, anyone in the market for hearing aids can start their journey with the AirPods Pro and its companion free audio test. If you like the results, you’re done — or you at least have a stopgap solution. And if not, you can compare and contrast them against pricier OTC or clinical options in terms of comfort, battery life, ease of use and — of course — the respective efficacy of their actual hearing assistance. The very fact that Apple is in the hearing aid conversation with a $200-ish option feels like a win.

Are you looking for a pair of earbuds that will let you enjoy music on your commute without costing so much you have to cut out your daily iced coffee? Well, Anker’s Soundcore Space A40 wireless earbuds are 40 percent off right now, dropping to $48, down from $80. This deal brings the earbuds to a record-low price — by $1, but, hey, we’ll take it.
We named Anker’s Soundcore Space A40 as our choice for best budget wireless earbuds in 2024 for quite a few reasons. For starters, the earbuds offer the quality and features — including active noise cancellation — that you typically need to spend way more money to get. They offer wireless charging, an IPX4 water-resistance rating and the ability to connect to two devices at once. The battery lasts about 10 hours on its own and 50 hours with the case. You can also get about four hours of juice after just ten minutes of charge.
The sound quality isn’t going to be the same level as what you’d get from Bose or Sony, with a slight dulling of finer details. However, the Soundcore Space A40 earbuds do offer custom EQ tools through the Soundcore app, so you can tweak it a bit. Overall, between offering ANC and pretty good comfort, these earbuds are a steal at this price.

OpenAI has unveiled yet another artificial intelligence model. This one is called o1, and the company claims it can perform complex reasoning tasks more effectively than its predecessors. Apparently, o1 was trained to “spend more time thinking through problems before they respond.” According to the company: “[the models] learn to refine their thinking process, try different strategies and recognize their mistakes.”
That more considered response means it’s significantly slower at processing prompts than GPT-4o. And while it might be thinking more, o1 hasn’t solved the problem of hallucinations — a term for AI models making up information. OpenAI’s chief research officer Bob McGrew told The Verge, “We can’t say we solved hallucinations.”
The FixHub is a USB-C powered soldering iron designed to help fix whatever’s on your workbench (and be easily fixable itself). The iron includes a 55Wh battery pack, which acts as a stand and temperature control. Founder Kyle Wiens told Engadget FixHub was born of frustration with soldering irons and their limits. So his company tried to fix those.
Elgato has introduced the Stream Deck Studio, a new version of its creative control tech targeting professionals. This 19-inch rackmount console has 32 LCD keys and two rotary dials. Oh, and a $900 price tag.
A decade — and countless clones — later, the original Flappy Bird is coming back. If you don’t recall the 2014 hit mobile game, you’d tap the screen to flap the bird’s wings and squeeze it through gaps between pipes. The game debuted in May 2013, but it didn’t blow up until the following January. Developer Dong Nguyen soon revealed the game was raking in $50,000 per day from advertising. He decided to remove the game, but clones of his creation persisted. Under the banner of the Flappy Bird Foundation, some dedicated fans acquired the rights to the game, officially, so now it’s flapping back.
A new, $26 solderless mod kit from 8BitDo can transform your old GameCube controller into a wireless Bluetooth device that works with Nintendo Switch and Android. It’ll also work with the original GameCube, but for that, you’ll have to buy the $26 Retro Receiver too. The mod kit comes with Hall Effect joysticks, a trigger pack and a rechargeable 300mAh battery, which 8BitDo says should get you around 6 hours of play time. Pre-orders for the kit are now open, and it’ll ship September 25.
Introducing the 8BitDo Mod Kit for Original NGC Controller. Easily modify your original wired NGC controller into a Bluetooth controller, bring wireless compatibility with Switch and Android. Including Hall Effect joysticks and the Trigger Pack.
There are numerous adapters on the market that will allow you to use an original wired GameCube controller with the Switch, including 8BitDo’s own GBros. adapter and an official one from Nintendo, but the mod kit cuts out the middleman to bring completely wireless Bluetooth connectivity. All you’d need to do is open up the controller and swap the old PCB with the new one.
