At this point, most competitive online multiplayer games on the PC come with some kind of kernel-level anti-cheat software. As we’ve written before, this is software that runs with more elevated privileges than most other apps and games you run on your PC, allowing it to load in earlier and detect advanced methods of cheating. More recently, anti-cheat software has started to require more Windows security features like Secure Boot, a TPM 2.0 module, and virtualization-based memory integrity protection.

Riot Games, best known for titles like Valorant and League of Legends and the Vanguard anti-cheat software, has often been one of the earliest to implement new anti-cheat requirements. There’s already a long list of checks that systems need to clear before they’ll be allowed to play Riot’s games online, and now the studio is announcing a new one: a BIOS update requirement that will be imposed on “certain players” following Riot’s discovery of a UEFI bug that could allow especially dedicated and motivated cheaters to circumvent certain memory protections.

In short, the bug affects the input-output memory management unit (IOMMU) “on some UEFI-based motherboards from multiple vendors.” One feature of the IOMMU is to protect system memory from direct access during boot by external hardware devices, which otherwise might manipulate the contents of your PC’s memory in ways that could enable cheating.

There’s a lot of goodwill out there for the Chevrolet Bolt. As maybe the first properly affordable longer-range electric car on the market, the Bolt wasn’t perfect. It didn’t charge very fast, and people found the seats quite uncomfortable. But it could get more than 230 miles on a single charge—a lot in 2017—and you didn’t have to be flush to afford one. Oh, and it was also pretty good to drive. I know I was a fan from the first time I tried a prototype at CES in 2016.

Understandably, Bolt fans were upset when Chevy decided to kill off the car. Yes, it lacked features compared to more modern EVs, but it is also the brand‘s bestselling EV by quite a country mile. “Not to worry,” said the executives, who told us they had something better coming built on the platform they used to call Ultium but don’t anymore. Starting at around the same $35,000 price tag the Bolt launched with, this would be the new Equinox EV.

That $34,995 price tag was perhaps a bit more appealing when the car was eligible for the now-dead $7,500 IRS clean vehicle tax credit. Truth be told, the LT1 spec is a little bare-boned, and you’ll need to step up to the LT2 we tested—which starts at $40,295—if you want things like heated seats or wireless charging for your devices. (The good news here is that people looking for a bargain should know that used Equinox EVs with decent specs are already much cheaper, just a year after the car’s launch.) And let’s not forget, when the Bolt was young, the more expensive trim was almost $42,000.

SEATTLE—The last coal-fired power plant in Washington state was set to go cold at the end of the year. It would then switch to natural gas, cutting carbon emissions in half.

The shutdown had been in the works for 15 years and was mandated by state law. It required the Canadian energy company that owns the power plant, TransAlta, to retrain workers and ease the local community’s economic transition.

But the farewell to coal was canceled this week by the Trump administration. In furtherance of the president’s crusade to keep America’s coal plants burning, the Department of Energy announced Tuesday that an “emergency exists” in the Pacific Northwest “due to a shortage of electricity.” To keep the lights on, Energy Secretary Chris Wright said that the Centralia electric generating facility in southwest Washington must continue to burn coal for at least 90 more days.

Instacart has agreed to pay out $60 million in subscriber refunds, the Federal Trade Commission announced on Thursday.

The refunds will help settle a lawsuit the FTC raised, accusing the grocery delivery app of engaging in “numerous unlawful tactics that harmed shoppers and raised the cost of grocery shopping for Americans.”

Under the settlement—which expires after 10 years—Instacart agreed to stop marketing its app with allegedly deceptive claims. That includes supposedly offering “free delivery,” when customers actually paid up to 15 percent in “service fees” not charged for pickup orders. Those service fees, the FTC alleged, were “just delivery fees by another name.”

Earlier this month, Strava, the popular fitness-tracking app, released its annual “Year in Sport” wrap-up—a cutesy, animated series of graphics summarizing each user’s athletic achievements.

But this year, for the first time, Strava made this feature available only to users with subscriptions ($80 per year), rather than making it free to everyone, as it had been historically since the review’s debut in 2016.

This decision has roiled numerous Strava users, particularly those who have relished the app’s social encouragement features. One Strava user in India, Shobhit Srivastava, “begged” Strava to “let the plebs see their Year in Sport too, please.” He later explained to Ars that having this little animated video is more than just a collection of raw numbers.

The idea of using AI to help with computer programming has become a contentious issue. On the one hand, coding agents can make horrific mistakes that require a lot of inefficient human oversight to fix, leading many developers to lose trust in the concept altogether. On the other hand, some coders insist that AI coding agents can be powerful tools and that frontier models are quickly getting better at coding in ways that overcome some of the common problems of the past.

To see how effective these modern AI coding tools are becoming, we decided to test four major models with a simple task: re-creating the classic Windows game Minesweeper. Since it’s relatively easy for pattern-matching systems like LLMs to play off of existing code to re-create famous games, we added in one novelty curveball as well.

For several years now, in discussing plans for its human spaceflight program beyond the International Space Station, Russian officials would proudly bring up the Russian Orbital Station, or ROS.

The first elements of ROS were to launch in 2027 so it would be ready for human habitation in 2028. Upon completion in the mid-2030s, the station would encompass seven shiny new modules, potentially including a private habitat for space tourists. It would be so sophisticated that the station could fly autonomously for months if needed.

Importantly, the Russian station was also to fly in a polar orbit at about 400 km. This would allow the station to fly over the entirety of Russia, observing the whole country. It would be important for national pride because cosmonauts would not need to launch from Kazakhstan anymore. Rather, rockets launching from the country’s new spaceport in eastern Russia, the Vostochny Cosmodrome, would easily reach the ROS in its polar orbit.

Welcome to Edition 8.23 of the Rocket Report! Several new rockets made their first flights this year. Blue Origin’s New Glenn was the most notable debut, with a successful inaugural launch in January followed by an impressive second flight in November, culminating in the booster’s first landing on an offshore platform. Second on the list is China’s Zhuque-3, a partially reusable methane-fueled rocket developed by the quasi-commercial launch company LandSpace. The medium-lift Zhuque-3 successfully reached orbit on its first flight earlier this month, and its booster narrowly missed landing downrange. We could add China’s Long March 12A to the list if it flies before the end of the year. This will be the final Rocket Report of 2025, but we’ll be back in January with all the news that’s fit to lift.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Rocket Lab delivers for Space Force and NASA. Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new spacecraft design, Ars reports. The satellites were nestled inside a cylindrical dispenser on top of the 59-foot-tall (18-meter) Electron rocket when it lifted off from NASA’s Wallops Flight Facility. A little more than an hour later, the rocket’s upper stage released the satellites one at a time at an altitude of about 340 miles (550 kilometers). The launch was the starting gun for a proof-of-concept mission to test the viability of a new kind of satellite called DiskSats, designed by the Aerospace Corporation.

After a year of stalled negotiations, TikTok owner ByteDance has reportedly agreed to Donald Trump’s deal giving US owners majority ownership of the app.

By signing the agreements, ByteDance has ended a prolonged period of uncertainty for millions of Americans who rely on TikTok for news, entertainment, social connection, and income. Under a law that Trump declined to enforce—which lawmakers convinced the Supreme Court was critical for national security—TikTok risked a US ban next year if the sale did not go through.

According to Reuters, terms of the deal match what was reported in September when Trump controversially confirmed that ByteDance would keep the algorithm. Under the deal, US investors and allies—including cloud computing firm Oracle, private equity group Silver Lake, and Abu Dhabi-based MGX—will likely license the algorithm.

It may be happening quietly, but there is a revolution taking place with in-space transportation, and it opens up a world of possibilities.

In January, a small spacecraft built by a California-based company called Impulse Space launched along with a stack of other satellites on a Falcon 9 rocket. Upon reaching orbit, the rocket’s upper stage sent the satellites zipping off on their various missions.

And so it went with the Mira spacecraft built by Impulse, which is known as an orbital transfer vehicle. Mira dropped off several small CubeSats and then performed a number of high-thrust maneuvers to demonstrate its capabilities. This was the second flight by a Mira spacecraft, so Impulse Space was eager to continue testing the vehicle in flight.

It probably sucked to be a Roman soldier guarding Hadrian’s Wall circa the third century CE. W.H. Auden imagined the likely harsh conditions in his poem “Roman Wall Blues,” in which a soldier laments enduring wet wind and rain with “lice in my tunic and a cold in my nose.” We can now add chronic nausea and bouts of diarrhea to his list of likely woes, thanks to parasitic infections, according to a new paper published in the journal Parasitology.

As previously reported, archaeologists can learn a great deal by studying the remains of intestinal parasites in ancient feces. For instance, in 2022, we reported on an analysis of soil samples collected from a stone toilet found within the ruins of a swanky 7th-century BCE villa just outside Jerusalem. That analysis revealed the presence of parasitic eggs from four different species: whipworm, beef/pork tapeworm, roundworm, and pinworm. (It’s the earliest record of roundworm and pinworm in ancient Israel.)

Later that same year, researchers from the University of Cambridge and the University of British Columbia analyzed the residue on an ancient Roman ceramic pot excavated at the site of a 5th-century CE Roman villa at Gerace, a rural district in Sicily. They identified the eggs of intestinal parasitic worms commonly found in feces—strong evidence that the 1,500-year-old pot in question was most likely used as a chamber pot.

A couple of hours after a judge formally swore in private astronaut Jared Isaacman as the next administrator of NASA on Thursday, President Donald Trump signed an executive order outlining his space policy objectives for the next three years.

The executive order, titled “Ensuring American Space Superiority,” states that the country must “pursue a space policy that will extend the reach of human discovery, secure the nation’s vital economic and security interests, unleash commercial development, and lay the foundation for a new space age.”

White House sets priorities

There is nothing Earth-shattering in the new executive order, as much of it builds on previously announced policies that span multiple administrations. There are some notable points in the document that clearly reflect the White House’s priorities, though, and Isaacman’s leadership of NASA.

Google is generally happy to see people using generative AI tools to create content, and it’s doubly happy when they publish it on its platforms. But there are limits to everything. Two YouTube channels that attracted millions of subscribers with AI-generated movie trailers have been shuttered.

Screen Culture and KH Studio flooded the site with fake but often believable trailers. The channels, which had a combined audience of more than 2 million subscribers, became a thorn in Google’s side in early 2025 when other YouTubers began griping about their sudden popularity in the age of AI. The channels produced videos with titles like “GTA: San Andreas (2025) Teaser Trailer” and “Malcom In The Middle Reboot (2025) First Trailer.” Of course, neither of those projects exist, but that didn’t stop them from appearing in user feeds.

Google demonetized the channels in early 2025, forcing them to adopt language that made it clear they were not official trailers. The channels were able to monetize again, but the disclaimers were not consistently used. Indeed, many of the most popular videos from those channels in recent months included no “parody” or “concept trailer” disclosures. Now, visiting either channel’s page on YouTube produces an error reading, “This page isn’t available. Sorry about that. Try searching for something else.”

Peacock subscribers will see ads immediately upon opening the streaming app or website next year. It’s a bold new strategy for attracting advertisers—something that’s been increasingly important to subscription-based streaming services—but it also risks alienating viewers

As reported by Variety, the new type of ads will display on the profile selection page that shows when a subscriber launches Peacock. Starting next year, instead of the profile page just showing your different Peacock profiles, most of the page will be dominated by an advertorial image. The circles of NBCUniversal-owned characters selected for user profiles will be relegated to a vertical column on the screen’s left side, as you can see here.

To avoid seeing what NBCUniversal is calling “Arrival Ads” every time you open Peacock, you need to subscribe to Peacock’s most expensive plan, which is ad-free and starts at $17 per month (Peacock’s ad-based plans start at $8/month.)

If you’ve been too busy planning for Half-Life 3 to take part in this year’s Ars Technica Charity Drive sweepstakes, don’t worry. You still have time to donate to a good cause and get a chance to win your share of over $4,000 worth of swag (no purchase necessary to win).

In the first week or so of the drive, over 300 readers have contributed nearly $18,000 to either the Electronic Frontier Foundation or Child’s Play as part of the charity drive (Child’s Play has a roughly 55/45 donation lead at the moment). That’s still a long way from 2020’s record haul of over $58,000, but there’s plenty of time until the Charity Drive wraps up on Friday, January 2, 2026.

That doesn’t mean you should put your donation off, though. Do yourself and the charities involved a favor and give now while you’re thinking about it.

The first few months of 2025 were full of graphics card reviews where we generally came away impressed with performance and completely at a loss on availability and pricing. The testing in these reviews is useful regardless, but when it came to extra buying advice, the best we could do was to compare Nvidia’s imaginary pricing to AMD’s imaginary pricing and wait for availability to improve.

Now, as the year winds down, we’re facing price spikes for memory and storage that are unlike anything I’ve seen in two decades of pricing out PC parts. Pricing for most RAM kits has increased dramatically since this summer, driven by overwhelming demand for these parts in AI data centers. Depending on what you’re building, it’s now very possible that the memory could be the single most expensive component you buy; things are even worse now than they were the last time we compared prices a few weeks ago.

Some SSDs are getting to the point where they’re twice as expensive as they were this summer (for this comparison, I’ve swapped the newer WD Blue SN5100 pricing in for the SN5000, since the drive is both newer and slightly cheaper as of this writing). Some RAM kits, meanwhile, are around four times as expensive as they were in August. Yeesh.

A Florida middle school was locked down last week after an AI security system called ZeroEyes mistook a clarinet for a gun, reviving criticism that AI may not be worth the high price schools pay for peace of mind.

Human review of the AI-generated false flag did not stop police from rushing to Lawton Chiles Middle School. Cops expected to find “a man in the building, dressed in camouflage with a ‘suspected weapon pointed down the hallway, being held in the position of a shouldered rifle,'” a Washington Post review of the police report said.

Instead, after finding no evidence of a shooter, cops double-checked with dispatchers who confirmed that a closer look at the images indicated that “the suspected rifle might have been a band instrument.” Among panicked students hiding in the band room, police eventually found the suspect, a student “dressed as a military character from the Christmas movie Red One for the school’s Christmas-themed dress-up day,” the Post reported.

There have been a number of high-profile cases where scientific papers have had to be retracted because they were filled with AI-generated slop—the most recent coming just two weeks ago. These instances raise serious questions about the quality of peer review in some journals—how could anyone let a figure with terms like “runctitional,” “fexcectorn,” and “frymblal” through, especially given the ‘m’ in frymblal has an extra hump? But it has not been clear whether these high-profile examples are representative. How significantly has AI use been influencing the scientific literature?

A collaboration of researchers at Berkeley and Cornell have decided to take a look. They’ve scanned three of the largest archives of pre-publication papers and identified ones that are likely to have been produced using Large Language Models. And they found that, while researchers produce far more papers after starting to use AI and the quality of the language used went up, the publication rate of these papers has dropped.

Searching the archives

The researchers began by obtaining the abstracts of everything placed in three major pre-publication archives between 2018 and mid-2024. At the arXiv, this netted them 1.2 million documents; another 675,000 were found in the Social Science Research Network; and bioRxiv provided another 220,000. So, this was both a lot of material to work with and covered a lot of different fields of research. It also included documents that were submitted before Large Language Models were likely to be able to produce output that would be deemed acceptable.

Guitarists today are spoiled for choice, and that goes doubly true for players who use computer-based amp modeling software. I’m one such player, and I don’t miss the size, weight, deafening volume, or cost of owning an amp and cabinet collection, to say nothing of all those pedals and cables. For clean to mid-gain tones alone, I already have more terrific options than I need, including Neural DSP’s Tone King and Cory Wong and Mateus Asato, Polychrome DSP’s Lumos, and Universal Audio’s new Paradise Guitar Studio. All work slightly differently, but they can each output record-ready tones that are really, really close to the (often incredibly expensive) hardware that they model, and they each give you plenty of great-sounding presets to start from.

So do we really need one amp sim package?

Neural DSP thinks we do, because the Finnish company just dropped a major new release yesterday called Archetype: John Mayer X. It doesn’t model Mayer’s type of gear but his actual hardware units, along with all the actual settings he uses in the studio and on stage. It even has some presets that he designed. Which is great if you want to sound like John Mayer—but what does the software offer for those of us not trying to cover Continuum?
