Planet orbits so close to its star that their magnetic fields connect

Planet orbits so close to its star that their magnetic fields connect

fivenewscrypto    juin 27, 2026   

For most of human history, our view of "close to the Sun" was defined by the orbit of Mercury, with its 88-day orbit and barren, baking surface. But from the moment we started discovering exoplanets, it became very clear that our own Solar System was anything but a guide to the rest of the galaxy. Planets with orbits only a few days long are strikingly common, with the proximity to the star creating things that seem bizarre from our perspective: metal vapor in the atmosphere, or atmospheres puffed out to ridiculously low densities.

Now, we can apparently add an additional oddity: overlapping magnetic fields. Researchers have found a star/planet combo that experiences periodic brightening, which they ascribe to the interactions between the magnetic fields of both bodies.

Looking for repetition

This is one of those cases where theory came before discovery. People had already proposed that a planet orbiting close to its host star could interact with it if its magnetic field were sufficiently strong. And, in a number of cases, researchers have found evidence that this is happening, with one case of an extremely young star emitting flares seemingly in response to the orbit of its innermost planet.

Feds deny Polestar authorization to sell cars in US from model year 2027

Feds deny Polestar authorization to sell cars in US from model year 2027

fivenewscrypto    juin 26, 2026   

The electric car brand Polestar's days in the US are seriously numbered. Today, the company revealed that the US Commerce Department has declined to authorize imports of new Polestars from model year 2027 onward as part of a rule banning connected cars from automakers with Chinese links.

Polestar says it will continue to sell its existing stock of Polestar 3 and Polestar 4 SUVs and "will continue to support customers, including providing access to its service network." But we can forget about the Polestar 5 sedan, the Polestar 6 roadster, or any future models making it to these shores.

The automaker was spun out of Volvo Cars several years ago as a pure EV brand by its corporate parent, Zhejiang Geely Holding, a Chinese company that also owns OEMs like Lynk and Co and Zeekr. And just weeks ago, Commerce authorized Volvo to import MY27 vehicles. At the time, Polestar told Ars that it was continuing to work with US authorities to meet the regulations; that work was evidently in vain.

Apple ratchets up prices, blames the cost of memory

Apple ratchets up prices, blames the cost of memory

fivenewscrypto    juin 26, 2026   

Apple bumped its prices across much of its product lineup today, in some cases adding hundreds of dollars to the cost of a new Macintosh. An entry-level MacBook Neo that cost $599 is now $699. The formerly $1,299 iMac will now be a $1,499 iMac. An M5 MacBook Pro that was $1,699 is now $1,999. And at the very high end, an M3 Ultra Mac Studio—which features 96GB of memory—sees a $1,300 price increase to $5,299.

The iPad line is also getting more expensive, between $100 and $200, depending on the model. Smaller price increases have been applied to products like the Apple TV and HomePod. The price of iPhones remains unchanged, at least for now.

The culprit? The soaring price of memory, according to an interview that Apple CEO Tim Cook gave to The Wall Street Journal earlier this month. “Unfortunately, price increases are unavoidable,” Cook told the paper. “We’re doing our best to mitigate the huge increases that are being passed to us, and we’ve been trying to shield our customers from the increases, but the situation has become unsustainable.”

IBM claims world’s first sub-1 nanometer chip technology

IBM claims world’s first sub-1 nanometer chip technology

fivenewscrypto    juin 26, 2026   

A new chip architecture from IBM can integrate nearly 100 billion transistors on a chip the size of a human fingernail—nearly twice the transistor density of the company’s previous generation of chip technology. The resulting improvement in chip compute performance and energy efficiency comes from what IBM describes as the “world’s first sub-1 nanometer chip technology” for AI data centers.

“It's not just an incremental step, it's a meaningful leap forward,” said Jay Gambetta, director of IBM Research and IBM Fellow, in an advance media briefing. He described the new chip technology as “pointing to a future where computing becomes significantly more powerful without a corresponding increase in energy.”

It’s worth unpacking what the “world’s first sub-1 nanometer chip technology” means, because it is impractical to build reliably functional chips with transistors and other features smaller than 1 nanometer due to various physical limitations. Instead, IBM is basically claiming that its new “nanostack” architecture can deliver the computing performance improvements that would be expected if a theoretical chip could be built with physical features smaller than 1 nanometer.

US ends hantavirus outbreak response with no answers on draconian quarantines

US ends hantavirus outbreak response with no answers on draconian quarantines

fivenewscrypto    juin 26, 2026   

The US response to the hantavirus cruise ship outbreak has concluded with no cases among American passengers but plenty of questions on the responses from Trump administration officials.

The US's response to the outbreak ended on Sunday, June 21, with the final 42-day monitoring period wrapping up for passengers of the virus-stricken cruise ship, MV Hondius. But without explanation, the Department of Health and Human Services announced the end of the response today, June 24, with a press release dated June 23.

Anti-vaccine Health Secretary Robert F. Kennedy Jr. touted how HHS acted "swiftly" to respond to the outbreak and credited federal efforts for preventing "sustained transmission of hantavirus... in the United States," despite no Americans bringing the virus into the country for sustained transmission to be possible.

One-two punch delivered in global operation disrupts cybercrime "assembly line"

One-two punch delivered in global operation disrupts cybercrime "assembly line"

fivenewscrypto    juin 26, 2026   

International authorities and a raft of private technology companies say they have disrupted a cybercrime “assembly line” that allowed crooks to collect millions of login credentials and steal more than $47 million in ransom payments and by other fraudulent means.

The crux of the operation was the simultaneous targeting of two unrelated tools that are widely used in various online scams. The first is Amadey, a malware-as-a-service platform for compromising devices and delivering malicious payloads for ransomware and other scams. Amadey has been observed in the wild since at least 2018 and was seen last year abusing GitHub as it collected system information from infected devices and installed customized payloads. The second tool was StealC, an infostealer-as-a-service platform that collects credentials, authentication cookies, cryptocurrency wallets, browser extensions, and files whose names match customer-defined patterns.

Severing a critical link in the cybercrime chain

Amadey and StealC are separate tools that are run independently of each other. Given their widespread use, however, many customers use both in their individual cybercrime activities. The tools also, it turns out, relied on some of the same underlying infrastructure to run. Microsoft said it made this determination after analyzing the tools using AI. This insight allowed Microsoft attorneys to seek an order disrupting both at the same time.

Underpromise, overdeliver? Hands-on with the $24,950 Slate auto.

Underpromise, overdeliver? Hands-on with the $24,950 Slate auto.

fivenewscrypto    juin 26, 2026   

Slate provided flights from San Francisco to Los Angeles and accommodation so Ars could ride in the Slate truck. Ars does not accept paid editorial content.

LOS ANGELES—Slate Auto has pulled a Disneyland. Let me explain.

At Disneyland, if a sign for a ride says the wait is 45 minutes, it's actually less than that. The idea is to set expectations low and then exceed them. Slate originally said its electric truck's entry-level battery would have 180 miles (290 km) of range, but that has expanded to 205 miles (330 km). The tow rating was originally 1,000 lbs (454 kg); now it's 2,000 lbs (907 kg), a nice jump. Finally, the load rating was 1,400 lbs (635 kg), and it's now 1,550 lbs (703 kg).

The automotive startup has exceeded expectations. Was it part of the plan all along? Was leaking the price of the base model of $24,950 last week guerrilla marketing? Since the truck's unveiling a year ago, Slate's marketing has been extremely tongue-in-cheek.
