Why Volvo Is Replacing Every EX90's Central Computer (insideevs.com) 55

An anonymous reader quotes a report from InsideEVs: On Monday morning, I spoke to a Volvo EX90 owner who reported a litany of issues with her 2025 EX90: malfunctioning phone-as-a-key functionality, a useless keyfob, a keycard that rarely worked quickly, constant phone connection issues, infotainment glitches and error messages. I was surprised not because I hadn't heard of these kinds of problems, but because I experienced them myself over a year ago at the EX90 first drive again. At the time, Volvo said software fixes were imminent. Today, we know the issues go deeper. To solve them, Volvo announced on Tuesday that it will replace the central computer of every 2025 EX90 with the new one from the 2026 EX90. It's a tacit admission that the company can't solve the EX90's issues while simultaneously launching its next-generation software-defined vehicles, and that it's easier to replace the original computer than to build bug-free software for it. But for some, the damage to the Volvo brand has already been done. "I say without exaggeration that this car is a dumpster fire inside a train wreck," InsideEVs reader and EX90 owner Sally Greer told InsideEVs.

The report notes that Volvo will replace the computer inside the 2025 EX90 with a Nvidia Drive AGX Orin-based core computer that has contains over 500 TOPS (Trillion Operations Per Second) of power, which Volvo says will help power its autonomous driving ambitions.

MLB Approves Robot Umps In 2026 For Challenges (espn.com) 22

MLB has approved the use of robot umpires in the 2026 season. According to ESPN, the system will give teams two challenges per game for balls and strikes where hitters, pitchers, and catchers can request reviews. From the report: Hitters, pitchers and catchers will be the only ones allowed to trigger the system by tapping their head, and if a challenge is successful -- the pitch will be shown on in-stadium videoboards -- teams will retain it. While the vote in favor of the automated ball-strike challenge system was not unanimous -- some of the four players on the 11-man committee voted no, according to sources -- the vote was a fait accompli, with MLB owners all in favor and in possession of a six-seat majority on the committee.

The ABS system uses similar technology to the line-calling system in tennis, with 12 cameras in each ballpark tracking the ball with a margin of error around one-sixth of an inch. The ABS zone will be a two-dimensional plane in the middle of the plate that spans its full width (17 inches). The zone's top will be 53.5% of a player's height and the bottom 27%. Teams that run out of challenges over the first nine innings will be granted an extra challenge in the 10th inning, while those that still have unused challenges will simply carry them into extras. If a team runs out of challenges in the 10th, it will automatically receive another in the 11th -- a rule that extends for any extra inning.

During the league's spring training test this season, teams combined to average around four challenges per game and succeeded 52.2% of the time, according to the league. Catchers, whose value in framing pitches outside the zone to look like strikes could take a hit due to the new rule, were the most successful at a 56% overturn rate, while hitters were correct 50% of the time and pitchers 41%. MLB's minor league testing, which started in 2021, led to Triple-A players in 2023 using ABS challenge three days a week and a full ABS system, with every pitch adjudicated by computer, the other three.

MediaTek Launches Improved AI Processor To Compete With Qualcomm 2

An anonymous reader quotes a report from Bloomberg: MediaTek is launching a mobile processor more capable of handling agentic AI tasks on devices, positioning to better compete with Qualcomm. The new Dimensity 9500 will provide users with better summaries of calls and meetings, improved output from AI models and superior 4K photos, the Taiwanese company said in a statement. The chip is made using an advanced 3-nanometer process by Taiwan Semiconductor Manufacturing Co., according to MediaTek, and handsets carrying the new chip will become available in the fourth quarter.

Xiaomi is set to launch its latest handset range powered by Qualcomm's newest Snapdragon processor later this week, and the Chinese smartphone maker is aiming to benchmark its upcoming devices against Apple Inc.'s iPhone 17. MediaTek's processor, meanwhile, is expected to give Xiaomi's rivals including Vivo a boost in the premium segment. [...] Separately, the Taiwanese company is preparing to place chip orders for automotive and more sensitive applications with TSMC's Arizona plant as some US customers have security concerns, according to the executives.

Is There a Market for Meta's Ray-Ban Display Smart Glasses? (How About the Blind?) (msn.com) 22

It's not just glitches at the launch of the Meta Ray-Ban Display smart glasses... The New York Times remains skeptical of its market share: [Meta's] smart glasses remain a niche. As of February, Meta had sold about two million of its $300 Ray-Ban Meta camera glasses since their 2023 debut, and it hopes to sell 10 million annually by the end of 2026, which is a tiny amount for a company this size. In the last decade, Meta has spent over $100 billion on its virtual and augmented reality division, which includes its smart glasses and is not profitable. Last quarter, the division reported a $4.5 billion loss, nearly the same as a year ago.
"Meta's Smart Glasses Might Make You Smarter. They'll Certainly Make You More Awkward," joked a recent Wired headline.

But the Wall Street Journal does report there's "a growing group of blind users... finding the devices to be more of a life-enhancing tool than a cool accessory." Jonathan Mosen, executive director at the nonprofit National Federation of the Blind said he'd like to see Meta continue to invest in the glasses. "It's giving significant accessibility benefits at a price point people can afford." He has used them a few times to record video of ride-share drivers refusing to give him and his wife a ride because she travels with a guide dog. Denying rides to people with service animals is illegal in many countries, including the U.S.

Another concern for blind users is that AI assistants in general are prone to making errors, or so-called hallucinations, which may not be apparent. Aaron Preece, who is blind and editor in chief of American Foundation for the Blind's AccessWorld magazine, said Meta's glasses recently failed to correctly read the number on the door to his home. "I just can't trust it," he said. "It's more of a novelty than something I'd use on a day-to-day basis."

When it comes to innovative technology, CNET seems more excited about Meta's display-controlling "neural wristband" accessory. Instead of camera-based hand tracking, these muscle-sensing bands "can register gestural moves like pinches, taps, thumb swipes, and maybe even typing over time..."

More Durable UV Coating For Solar Panels Made From Red Onion Skins (zmescience.com) 39

Long-time Slashdot reader fahrbot-bot shared this report from ZME Science Researchers from the University of Turku, in collaboration with Aalto University and Wageningen University, have developed a bio-based UV protection film for solar cells that not only blocks nearly all harmful ultraviolet light but also outperforms commercial plastic films. The key ingredient is a water extract made from red onion skins...

[T]he same sunlight that powers [solar cells] can also degrade their delicate components — particularly the electrolyte inside dye-sensitized solar cells (DSSCs), a type known for their flexibility and low-light performance. To mitigate this, manufacturers typically wrap cells in UV-protective films made from petroleum-based plastics like polyethylene terephthalate (PET). But these plastics degrade over time and are difficult to recycle... Nanocellulose can be processed into thin, transparent films that serve as the perfect substrate for UV-blocking compounds.

Their breakthrough came when they dyed these films using an extract from red onion skins, a common kitchen waste. The result was a filter that blocked 99.9% of UV radiation up to 400 nanometers, a feat that outstripped even the PET-based commercial filters chosen for comparison... [T]he onion-treated filter excelled: it let through over 80% of light in the 650-1,100 nm range — an ideal sweet spot for energy absorption... Even predictive modeling based on early degradation trends suggested the CNF-ROE filter could extend a solar cell's lifetime to roughly 8,500 hours. The PET-based filter? Just 1,500 hours... [T]he red onion extract offered a rare combination of longevity, transparency, and sustainability...

The team envisions biodegradable solar cells for smart packaging, remote sensors, or wearable devices — especially in applications where recovery and recycling are not feasible. Their work is part of the BioEST project, funded by the Research Council of Finland, which supports sustainable innovation across electronics and materials science. This achievement taps into a broader movement to decarbonize every step of solar energy production. Plastic packaging is one of the overlooked sources of emissions in clean technology. Swapping out fossil-based plastics for biodegradable alternatives helps close that loop...

The findings appeared in the journal Applied Optical Materials.

Meta Pushes Into Power Trading as AI Sends Demand Soaring (yahoo.com) 17

Meta is moving to break into the wholesale power-trading business to better manage the massive electricity needs of its data centers. Bloomberg: The company, which owns Facebook, filed an application with US regulators this week seeking authorization to do so. A Meta representative said it was a natural next step to participate in energy markets as it looks to power operations with clean energy.

Buying electricity has become an increasingly urgent challenge for technology companies including Meta, Microsoft and Alphabet's Google. They're all racing to develop more advanced artificial intelligence systems and tools that are notoriously resource-intensive. Amazon, Google and Microsoft are already active power traders, according to filings with US regulators.

What's Happening To Wholesale Electricity Prices? (construction-physics.com) 120

US wholesale electricity prices have nearly doubled since 2020, rising faster than consumer rates across most regional grid operators. Analysis of location marginal pricing data from 17 trading hubs shows average wholesale costs increased from baseline 2020 levels to peaks 2-4 times higher by 2022, before partially recovering. Consumer electricity prices rose 35% during the same period.

Transmission congestion spreads are widening in most Independent System Operators and Regional Transmission Organizations, particularly in PJM, SPP, and NYISO, where bottlenecks increasingly prevent access to cheaper generation. California's CAISO stands alone among major grid operators as wholesale prices remain flat or decline in 2025 despite natural gas volatility. The cheapest wholesale electricity continues to trade in SPP's Oklahoma-Kansas region at $16-17 per megawatt-hour.

Consumer Reports Asks Microsoft To Keep Supporting Windows 10 (theverge.com) 137

Consumer Reports has urged Microsoft to keep supporting Windows 10 beyond its October 2025 cutoff, saying the move will "strand millions of consumers" who have machines incompatible with Windows 11. The Verge reports: As noted by Consumer Reports, data suggests that around 46.2 percent of people around the world still use Windows 10 as of August 2025, while around 200 to 400 million PCs can't be upgraded to Windows 11 due to missing hardware requirements.

In the letter, Consumer Reports calls Microsoft "hypocritical" for urging customers to upgrade to Windows 11 to bolster cybersecurity, but then leaving Windows 10 devices susceptible to cyberattacks. It also calls out the $30 fee Microsoft charges customers for "a mere one-year extension to preserve their machine's security," as well as the free support options that force people to use Microsoft products, allowing the company to "eke out a bit of market share over competitors."

Consumer Reports asks that Microsoft continue providing support for Windows 10 computers for free until more people have upgraded to Windows 11.

Hard Drive Shortage Intensifies as AI Training Data Pushes Lead Times Beyond 12 Months (tomshardware.com) 22

Lead times for high-capacity hard drives have exceeded 52 weeks as AI workloads drive unprecedented demand for warm storage that sits between fast SSDs and offline tape archives, according to TrendForce. Western Digital notified customers of price increases across its entire hard drive portfolio citing demand for "every capacity" in its product line.

The shortage stems from AI infrastructure requirements including training datasets, model checkpoints and inference logs that consume petabytes of storage space. These files are too large for primary SSD storage but must remain accessible for quick retrieval. Hard drive manufacturers have not significantly expanded production capacity in approximately a decade. Cloud service providers are evaluating QLC SSDs for cold data storage despite costs remaining four to five times higher per gigabyte than mechanical drives. Memory suppliers are developing SSD products specifically for this intermediate storage tier.

'If We Want Bigger Wind Turbines, We're Gonna Need Bigger Airplanes' (ieee.org) 184

Long-time Slashdot reader schwit1 shared this article from IEEE Spectrum: The world's largest airplane, when it's built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that's sprouted wings — aeronautical engineering at a preposterous scale.

Called WindRunner, and expected by 2030, it'll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length of 70 meters, max. This size constraint comes not from the limits of blade engineering or physics; it's transportation. Any larger and the blades couldn't be moved over land, since they wouldn't fit through tunnels or overpasses, or be able to accommodate some of the sharper curves of roads and rails.

So the WindRunner's developer, Radia of Boulder, Colorado, has staked its business model on the idea that the only way to get extralarge blades to wind farms is to fly them there... Radia's plane will be able to hold two 95-meter blades or one 105-meter blade, and land on makeshift dirt runways adjacent to wind farms. This may sound audacious — an act of hubris undertaken for its own sake. But Radia's supporters argue that WindRunner is simply the right tool for the job — the only way to make onshore wind turbines bigger. Bigger turbines, after all, can generate more energy at a lower cost per megawatt. But the question is: Will supersizing airplanes be worth the trouble...?

Having fewer total turbines means a wind farm could space them farther apart, avoiding airflow interference. The turbines would be nearly twice as tall, so they'll reach a higher, gustier part of the atmosphere. And big turbines don't need to spin as quickly, so they would make economic sense in places with average wind speeds around 5 meters per second compared with the roughly 7 m/s needed to sustain smaller units. "The result...is more than a doubling of the acres in the world where wind is viable," says Mark Lundstrom [Radia's founder and CEO].

The executive director at America's National Renewable Energy Laboratory Foundation points out that one day blades could just be 3D-printed on-site — negating the need for the airplane altogether. But 3D printing for turbines is still in its earliest stages.

A New Nuclear Rocket Concept Could Slash Mars Travel Time in Half (gizmodo.com) 47

"Engineers from Ohio State University are developing a new way to power rocket engines," reports Gizmodo, "using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year..." Nuclear propulsion uses a nuclear reactor to heat a liquid propellant to extremely high temperatures, turning it into a gas that's expelled through a nozzle and used to generate thrust. The newly developed engine concept, called the centrifugal nuclear thermal rocket (CNTR), uses liquid uranium to heat rocket propellant directly. In doing so, the engine promises more efficiency than traditional chemical rockets, as well as other nuclear propulsion engines, according to new research published in Acta Astronautica...

Traditional chemical engines produce about 450 seconds of thrust from a given amount of propellant, a measure known as specific impulse. Nuclear propulsion engines can reach around 900 seconds, with the CNTR possibly pushing that number even higher. "You could have a safe one-way trip to Mars in six months, for example, as opposed to doing the same mission in a year," Spencer Christian, a PhD student at Ohio State and leader of CNTR's prototype construction, said in a statement.

CNTR promises faster routes, but it could also use different types of propellant, like ammonia, methane, hydrazine, or propane, that can be found in asteroids or other objects in space.

"Some potential hurdles include ensuring that the methods used for startup, operation and shutdown avoid instabilities," according to the researchers' announcement, as well as "envisioning ways to minimize the loss of uranium fuel and accommodate potential engine failures."

But "This team's CNTR concept is expected to reach design readiness within the next five years..."

The World's EV Owners Discover Unheated Batteries Lose Distance in Freezing Weather (restofworld.org) 173

RestOfWorld.org reports on "a global crisis nobody anticipated when governments started subsidizing electric vehicles..."

"EVs can lose almost half their driving distance when temperatures drop, and the billions spent on improving technology have failed to fix this fundamental limitation." In January, Seattle-based Recurrent, a company that tests and analyzes EVs, found an average range loss of 20% in extreme cold... Lithium-ion batteries rely on chemical reactions that slow dramatically in cold weather. When temperatures plunge, the electrolyte thickens, ions move sluggishly, and charging becomes not just inefficient but potentially dangerous. Charging in cold weather has been identified as a primary cause of thermal acceleration, which can lead to fires...

The failure pattern repeats globally wherever cold weather meets inadequate infrastructure. Manufacturers, too, have acknowledged the problem. Chinese EV maker BYD's user manual, for instance, advises drivers to charge indoors, with the heating on. That advice is useless for farmers parking in open courtyards.

In fact, research across 293 Chinese cities "found that many drivers in colder regions buy EVs only as supplementary vehicles," according to the article, "while still relying on gasoline-powered cars during winter."

The article also tells the story of an apple grower chilly Kashmir, India who discovered that his Chinese three-wheeler lost 60% of its 10-hour charge overnight. This made it impossible to begin the 56-kilometer (35-mile) trip on a route with no charging stations — and prevented him from selling his produce while it was fresh (to earn the highest prices). And the problem affects the entire region: Desperate drivers have formed WhatsApp groups, such as "EV Apple Transporters" and "Battery Help Kashmir," sharing increasingly absurd workarounds. Some have wrapped batteries in quilts; others have hauled power packs weighing 90 kilograms (over 200 pounds) into their homes for the night. One driver parked his battery in the living room. "The blankets caused overheating on the road; water bottles leaked into the circuits," [orchard owner] Sajad Ahmad said. "We became mechanics, engineers, and fools all at once." EVs are also not considered cost-efficient. "Diesel vans are expensive, but they can do four or five trips a day," Mohammad Yaseen, a driver based in Shopian, told Rest of World. "With EVs, one half-trip and you're stuck."

Norway, where winter temperatures average minus 7 degrees Celsius (19 degrees Fahrenheit), achieved 89% EV market share with its comprehensive infrastructure. It offers more than 200 models for year-round usage. "The ability to preheat batteries upon fast charging in winter is by far the most important improvement we have seen in the past five years," Christina Bu, secretary-general of the Norwegian EV Association, told Rest of World.

"These features are standard in Norway's mature market, but remain absent from basic models exported to developing countries."

Apple Claims 'Most Significant Upgrade to Memory Safety' in OS History (apple.com) 39

"There has never been a successful, widespread malware attack against iPhone," notes Apple's security blog, pointing out that "The only system-level iOS attacks we observe in the wild come from mercenary spyware... historically associated with state actors and [using] exploit chains that cost millions of dollars..."

But they're doing something about it — this week announcing a new always-on memory-safety protection in the iPhone 17 lineup and iPhone Air (including the kernel and over 70 userland processes)... Known mercenary spyware chains used against iOS share a common denominator with those targeting Windows and Android: they exploit memory safety vulnerabilities, which are interchangeable, powerful, and exist throughout the industry... For Apple, improving memory safety is a broad effort that includes developing with safe languages and deploying mitigations at scale...

Our analysis found that, when employed as a real-time defensive measure, the original Arm Memory Tagging Extension (MTE) release exhibited weaknesses that were unacceptable to us, and we worked with Arm to address these shortcomings in the new Enhanced Memory Tagging Extension (EMTE) specification, released in 2022. More importantly, our analysis showed that while EMTE had great potential as specified, a rigorous implementation with deep hardware and operating system support could be a breakthrough that produces an extraordinary new security mechanism.... Ultimately, we determined that to deliver truly best-in-class memory safety, we would carry out a massive engineering effort spanning all of Apple — including updates to Apple silicon, our operating systems, and our software frameworks. This effort, together with our highly successful secure memory allocator work, would transform MTE from a helpful debugging tool into a groundbreaking new security feature.

Today we're introducing the culmination of this effort: Memory Integrity Enforcement (MIE), our comprehensive memory safety defense for Apple platforms. Memory Integrity Enforcement is built on the robust foundation provided by our secure memory allocators, coupled with Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and supported by extensive Tag Confidentiality Enforcement policies. MIE is built right into Apple hardware and software in all models of iPhone 17 and iPhone Air and offers unparalleled, always-on memory safety protection for our key attack surfaces including the kernel, while maintaining the power and performance that users expect. In addition, we're making EMTE available to all Apple developers in Xcode as part of the new Enhanced Security feature that we released earlier this year during WWDC...

Based on our evaluations pitting Memory Integrity Enforcement against exceptionally sophisticated mercenary spyware attacks from the last three years, we believe MIE will make exploit chains significantly more expensive and difficult to develop and maintain, disrupt many of the most effective exploitation techniques from the last 25 years, and completely redefine the landscape of memory safety for Apple products. Because of how dramatically it reduces an attacker's ability to exploit memory corruption vulnerabilities on our devices, we believe Memory Integrity Enforcement represents the most significant upgrade to memory safety in the history of consumer operating systems.

Wind and Solar Power Fuel Over One-Third of Brazil's Electricity For First Time (apnews.com) 46

Wind and solar power generated more than a third of Brazil's electricity in August, the first month on record the two renewable sources have crossed that threshold, according to government data made public on Thursday and analyzed by energy think tank Ember. AP: The clean energy sources accounted for 34% of the country's electricity generation last month, producing a monthly record of 19 terawatt-hours (TWh), enough to power about 119 million average Brazilian homes for a month, Ember told The Associated Press.

That surpassed the previous high of 18.6 TWh set in September 2024. The milestone came as hydroelectric output, Brazil's dominant power source, fell to a four-year low. "Brazil shows how a rapidly growing economy can meet its rising need for electricity with solar and wind," said Raul Miranda, Ember's global program director based in Rio de Janeiro.
