Microsoft ended official support for Windows 10 in 2025, but the company may have a harder time than expected putting the operating system out to pasture. After promising a year of optional extended update support, Microsoft has changed its policy, tacking on another year to its Extended Security Updates (ESU) program. If you are still clinging to Windows 10, you don't have to do anything but enjoy that extra year.

The last regular updates rolled out to Windows 10 in October of last year, but the Internet can be a dangerous place for unpatched Windows machines. That was a problem for Microsoft, as Windows 11 usage had only barely surpassed Windows 10 when support ended. Microsoft's solution was to give everyone on the old OS a free year of extended updates.

That program was set to end on October 12, 2026, but Microsoft has updated its policy with hardly a whisper, pushing back the end of extended updates to October 12, 2027. The ESU support page was updated with that date, and Microsoft's blog post on the program has a new editor's note confirming the change.

The Federal Communications Commission was roundly criticized today for proposing to scale back or eliminate E-Rate, a $2 billion-a-year Universal Service program that provides discounts for telecom services and equipment in schools and libraries.

FCC Chairman Brendan Carr said E-Rate should be changed because students are getting too much screen time. He led a 2-1 vote to issue a Notice of Proposed Rulemaking (NPRM) that proposes changes and asks the public to comment on them.

"Over the last decade, school districts across the country experimented with a massive increase in screen time for students," Carr said at today's meeting.

In February 2024, Notion bought Skiff, an encrypted email and productivity software startup. Within a year, Notion shut down Skiff’s email service (taking @skiff.com email addresses with it). And in April 2025, the San Francisco-based company released Notion Mail, a Gmail client primarily built by people who joined Notion through the Skiff acquisition. Today, Notion announced that it’s shutting down Notion Mail, effectively killing what little remained of Skiff email.

In an X post (first spotted by 9to5Mac) today, Notion said that it will shutter the Notion Mail “inbox across web, desktop, and iOS on September 22.”

The post claimed that most Notion users don’t use email clients anyway and instead rely on AI agents to handle their electronic correspondence. It reads:

Google Finance is not a new product—it has been around for 20 years, long enough that it initially relied on Flash to display charts and graphs. The website has gotten a few major updates over the years, but it has never had a mobile app until now. Google has released the first standalone app for Google Finance, which is currently exclusive to Android, with iOS planned for later this year.

The app is available globally in the Play Store, but that's not the only update to Google's financial tracker. The AI-powered makeover for the Finance website is also leaving beta, making Google's chatbot a core part of the experience. Naturally, the mobile app includes a heaping helping of generative AI that aims to make sense of irrational financial markets.

If you've checked out the new Finance web experience, you'll see a lot of familiar features in the app. You can create watchlists, monitor real-time market data, and keep up with financial news in one place. While perusing graphs of stock performance, Finance will use AI to generate "key moments" that can explain why the numbers changed. This feature initially launched in the Finance web interface in May.

Anthropic has accused the Chinese firm Alibaba of launching the largest attack yet attempting to clone Claude, as China races to match the capabilities of Anthropic's leading model following Mythos' release and subsequent restriction from foreign markets.

Ars obtained a June 10 letter sent to Senators Tim Scott (R-SC) and Elizabeth Warren (D-Mass.) one day ahead of a Senate committee hearing on “AI and the American Dream.” In the letter, Anthropic shared “new, confidential evidence of the largest campaign to illicitly extract Claude’s capabilities we have ever measured.”

The attacks occurred between April 22 and June 5, when “operators affiliated with Alibaba and Alibaba Qwen, Alibaba’s AI lab” allegedly generated “more than 28.8 million exchanges with Claude through almost 25,000 fraudulent accounts,” Anthropic said. Violating Claude's terms of service and access restrictions, this campaign “targeted some of Claude’s most valuable capabilities, such as agentic reasoning, software engineering, and long-horizon tasks.”

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.

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 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.”

Europe is in the midst of its second big heat wave of the year, and it’s breaking more records. France just recorded its hottest day ever, with temperatures exceeding 44° Celsius in some places. Around 40 people have drowned in local water bodies, likely attempting to escape the heat, and thousands more are without electricity.

As temperatures hit a sweltering 36° in some regions of the United Kingdom, schools canceled classes and train delays abounded. United Nations Secretary-General Antonio Guterres described London as “cooking.” As the city hosts its annual Climate Action Week, the UK meteorological service has issued a red alert for multiple regions, signaling that exceptionally hot and humid weather is forecasted and likely to impact the general public. Switzerland and Spain have also issued warnings to residents.

Emma Howard Boyd, the former chair of the London Climate Resilience Review who now chairs the National Heat Risk Commission in the UK, said that when it comes to heat resilience in the country, the problem is not just homes—which are usually not air-conditioned.

The US Endangered Species Act compels the government to identify species at risk of extinction and devise plans to restore populations and the habitats they depend on. It has seen some spectacular successes, such as the restoration of the bald eagle to much of its original range. But over 2,300 plant and animal populations remain on the list, requiring ongoing government intervention.

On Thursday, it was announced that all of those species would see their genomes sequenced and tissue samples preserved to aid future conservation efforts. The work will be done by a partnership between two unexpected parties. One is the US government, which has generally attempted to undercut the Endangered Species Act as part of its anti-regulatory efforts. It is joined by Colossal Biosciences, a biotech company that has a controversial take on what actually constitutes a species.

Colossal has always said it had a conservation focus, but its headline-grabbing efforts have been directed toward restoring species that have been driven to extinction. It intends to do that by developing a combination of gene editing and reproductive technologies that it expects it can profitably license. But its dire wolf announcement, in which only a tiny handful of genetic changes were edited in to grey wolves, have raised some questions about its seriousness regarding these efforts.

All the Homo naledi skeletons in Rising Star Cave are female, and that probably didn’t happen by accident.

In 2013, a team of anthropologists led by Lee Berger unearthed the remains of more than 20 small-bodied hominins (ancient relatives of humans), all 335,000 to 236,000 years old, from the Rising Star Cave System in South Africa. Excavations at Rising Star have sparked debate about whether these little hominins had all ended up in the caves by tragic accident, or whether they’d been carefully placed there by other members of their enigmatic species, dubbed Homo naledi.

Now there's a plot twist that may speak to how the remains got there: All of the hominins in Rising Star are female, at least according to the proteins in their dental enamel.

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.

It seems to some of us like just yesterday—even though the transition began more than half a decade ago—that gamers were getting adjusted to spending $70 on AAA game releases at launch instead of $60, but as preorders begin this week for the wildly anticipated Grand Theft Auto VI, they're finding that at least that title will sell for $80.

Additionally, disclaimers make it clear that the physical release of GTA6 will not include a physical disc. Instead, it will be a box with a download code inside it.

Three months ago, NASA Administrator Jared Isaacman announced the space agency was making a major pivot from building a space station in lunar orbit to a base on the surface. This "Ignition" event followed an earlier announcement in which NASA also said it was ending development of a new upper stage for its Space Launch System rocket.

In the aftermath of these decisions, there was some grumbling—mostly from contractors involved with the programs—that NASA was foolishly walking away from nearly complete hardware that the space agency needed for its Artemis Program.

Isaacman said these programs were not essential for landing humans on the Moon and added that they had cost far more than originally budgeted and had been subjected to years of delays. Moreover, they were still not ready.

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.
