When the first foldable phones came along, they seemed like a cool evolution of the traditional smartphone form factor and, if they got smaller and cheaper, like something people might actually want. After more than five years of foldable phones, we can probably give up on the latter. Google's new Pixel 10 Pro Fold retains the $1,800 price tag of last year's model, and while it's improved in several key ways, spending almost two grand on any phone remains hard to justify.

For those whose phones are a primary computing device or who simply love gadgets, the Pixel 10 Pro Fold is still appealing. It offers the same refined Android experience as the rest of the Pixel 10 lineup , with much more screen real estate on which to enjoy it. Google also improved the hinge for better durability, shaved off some bezel, and boosted both charging speed and battery capacity. However, the form factor hasn't taken the same quantum leap as Samsung's latest foldable.

An iterative (but good) design

The Pixel 10 Pro Fold doesn't reinvent the wheel—it looks and feels almost exactly like last year's foldable, with a few minor tweaks centered around a new "gearless" hinge. Dropping the internal gears allegedly helps make the mechanism twice as durable. Google claims the Pixel 10 Pro Fold's hinge will last for more than 10 years of folding and unfolding.

If you were considering the purchase of a Synology NAS but were leery of the unreasonably high cost of populating it with special Synology-branded hard disk drives, you can breathe a little easier today. In a press release dated October 8 , Synology noted that with the release of its latest Disk Station Manager (DSM) update, some of its 2025 model-year products—specifically, the Plus, Value, and J-series DiskStation NAS devices—would "support the installation and storage pool creation of non-validated third-party drives."

This unexpected move comes just a few months after Synology aggressively expanded its "verified drive" policy down-market to the entire Plus line of DiskStations. Prior to today, the network-attached storage vendor had shown no signs of swerving from the decision, painting it as a pro-consumer move intended to enhance reliability. "Extensive internal testing has shown that drives that follow a rigorous validation process when paired with Synology systems are at less risk of drive failure and ongoing compatibility issues," Synology previously claimed in an email to Ars.

What is a “verified” or “validated” drive?

Synology first released its own brand of hard disk drives back in 2021 and began requiring their use in a small but soon-to-increase number of its higher-end NAS products. Although the drives were rebadged offerings from other manufacturers—there are very few hard disk drive OEMs, and Synology isn't one of them—the company claimed that its branded disks underwent significant additional validation and testing that, when coupled with customized firmware, yielded reliability and performance improvements over off-the-shelf components.

"AI doesn't care," a vandal scrawled on a New York subway ad promoting a wearable AI pendant called Friend, which was designed to monitor a user's everyday conversations and serve as a companion "who listens, responds, and supports you."

"Human connection is sacred," the vandal wrote, emphasizing, "AI is not your friend."

This act of vandalism is now part of a huge online archive collecting defaced ads that the Friend campaign inspired, as many New Yorkers responded with vitriol to marketing claims that the AI "friend" would never "bail on dinner" or abandon you to ride the subway alone.

The polymers around us are basically a disordered mess, with long chains of atoms tangled around each other. But starting around 1990, chemists began developing techniques that allow us to build polymers with precisely defined structures. These polymers, called metal-organic frameworks (MOFs), have distinct chemical properties: large pores that can be used to filter or store gases, catalytic centers within the polymer, and more.

On Wednesday, the Nobel Prize Committee honored three researchers for their role in developing MOFs: Richard Robson for demonstrating the first MOF, and Susumu Kitagawa and Omar Yaghi for developing them to their full potential.

Building a structure

Most polymers are built from individual molecules that are linked together by flexible bonds, allowing the molecules to flop around. As a result, in their final form as something like a plastic bag or a bike tire, the polymers are a complicated tangle, with molecules wrapped around each other in no particular order. We can still control some aspects of the resulting polymer by manipulating its bulk properties or changing the molecules it's built from, but there's not a lot of chemistry we can do beyond that.

Blue Origin rolled the first stage of its massive New Glenn rocket from its hangar on Wednesday morning in Florida, kicking off the final phase of the campaign to launch the heavy-lift vehicle for the second time.

In sharing video of the rollout to Launch Complex-36 on Wednesday online , the space company did not provide a launch target for the mission, which seeks to put two small Mars-bound payloads into orbit. The pair of identical spacecraft to study the solar wind at Mars is known as ESCAPADE.

However, sources told Ars that on the current timeline, Blue Origin is targeting a launch window of November 9 to November 11. This assumes pre-launch activities, including a static-fire test of the first stage, go well.

OpenAI and Anthropic are considering using investor funds to settle potential claims from multibillion-dollar lawsuits, as insurers balk at providing comprehensive coverage for the risks associated with artificial intelligence.

The two US-based AI start-ups have traditional business insurance coverage in place, but insurance professionals said AI model providers will struggle to secure protection for the full scale of damages they may need to pay out in the future.

OpenAI, which has tapped the world’s second-largest insurance broker Aon for help, has secured cover of up to $300 million for emerging AI risks, according to people familiar with the company’s policy.

By now, a handful of technologies are leading contenders for producing a useful quantum computer. Companies have used them to build machines with dozens to hundreds of qubits, the error rates are coming down, and they've largely shifted from worrying about basic scientific problems to dealing with engineering challenges.

Yet even at this apparently late date in the field's development, there are companies that are still developing entirely new qubit technologies, betting the company that they have identified something that will let them scale in ways that enable a come-from-behind story. Recently, one of those companies published a paper that describes the physics of their qubit system, which involves lone electrons floating on top of liquid helium.

Trapping single electrons

So how do you get an electron to float on top of helium? To find out, Ars spoke with Johannes Pollanen, the chief scientific officer of EeroQ, the company that's done the new work. He said that it's actually old physics, with the first demonstrations of it having been done half a century ago.

Today, Tesla announced a new variant of the Model Y crossover for North America. Tesla fans have long-awaited a cheaper entry-level model; this was supposed to be the $25,000 Model 2. But the development of that electric vehicle was shelved earlier last year as CEO Elon Musk began to lose interest with car-making in favor of humanoid robots .

However, car sales still make up the overwhelming majority of Tesla's revenue, and the removal of the IRS clean vehicle tax credit at the end of September may have juiced US EV sales in Q3 2025, but sales are expected to dip significantly in the current quarter.

The new Standard Range Model Y starts at $39,990, with 321 miles (516 km) of range from its rear-wheel drive powertrain, compared to the now-Premium rear-wheel drive Model Y, which has an EPA range of 357 miles (574 km). In the past, Tesla has software-locked batteries to a smaller configuration; however, here we believe the Standard Range Model Y uses a 69 kWh pack.

The acting director of the Centers for Disease Control and Prevention has finally signed off on recommendations for this season's COVID-19 vaccines—and, with that, access to the shots will, in the end, look a lot like the access people had last year.

Here’s what to know

You still have access and coverage : For this year, anyone age 6 months and older will still have access to the shots, and the shots should be fully covered under private insurance plans and federal programs—including Medicare, Medicaid, Children’s Health Insurance Program, Vaccines for Children Program, and insurance plans regulated by the Affordable Care Act.

In fact, for private insurance plans, AHIP—the trade organization that represents major insurers—had already stated that regardless of how this year's messy federal recommendations ended up, private insurance plans would maintain their previous coverage with no cost sharing.
