A bundle of depleted batteries from the International Space Station careened around Earth for almost three years before falling out of orbit and plunging back into the atmosphere Friday. Most of the trash likely burned up during reentry, but it’s possible some fragments may have reached Earth’s surface intact.

Larger pieces of space junk regularly fall to Earth on unguided trajectories, but they’re usually derelict satellites or spent rocket stages. This involved a pallet of batteries from the space station with a mass of more than 2.6 metric tons (5,800 pounds). NASA intentionally sent the space junk on a path toward an unguided reentry.

Naturally self-cleaning

Sandra Jones, a NASA spokesperson, said the agency “conducted a thorough debris analysis assessment on the pallet and has determined it will harmlessly reenter the Earth’s atmosphere.” This was, by far, the most massive object ever tossed overboard from the International Space Station.

The batteries reentered the atmosphere at 2: 29 pm EST (1929 UTC), according to US Space Command. At that time, the pallet would have been flying between Mexico and Cuba. “We do not expect any portion to have survived reentry,” Jones told Ars.

The European Space Agency (ESA) also monitored the trajectory of the battery pallet. In a statement this week, the ESA said the risk of a person being hit by a piece of the pallet was “very low” but said “some parts may reach the ground.” Jonathan McDowell, an astrophysicist who closely tracks spaceflight activity, estimated about 500 kilograms (1,100 pounds) of debris would hit the Earth’s surface.

“The general rule of thumb is that 20 to 40 percent of the mass of a large object will reach the ground, though it depends on the design of the object,” the Aerospace Corporation says.

A dead ESA satellite reentered the atmosphere in a similar uncontrolled manner February 21. At 2.3 metric tons, this satellite was similar in mass to the discarded battery pallet. ESA, which has positioned itself as a global leader in space sustainability, set up a website that provided daily tracking updates on the satellite’s deteriorating orbit.

This map shows the track of the unguided cargo pallet around the Earth over the course of six hours Friday. It reentered the atmosphere near Cuba on southwest-to-northeast heading.

As NASA and ESA officials have said, the risk of injury or death from a spacecraft reentry is quite low. Falling space debris has never killed anyone. According to ESA, the risk of a person getting hit by a piece of space junk is about 65,000 times lower than the risk of being struck by lightning.

This circumstance is unique in the type and origin of the space debris, which is why NASA purposely cast it away on an uncontrolled trajectory back to Earth.

The space station’s robotic arm released the battery cargo pallet on March 11, 2021. Since then, the batteries have been adrift in orbit, circling the planet about every 90 minutes. Over a span of months and years, low-Earth orbit is self-cleaning thanks to the influence of aerodynamic drag. The resistance of rarefied air molecules in low-Earth orbit gradually slowed the pallet’s velocity until, finally, gravity pulled it back into the atmosphere Friday.

The cargo pallet, which launched inside a Japanese HTV cargo ship in 2020, carried six new lithium-ion batteries to the International Space Station. The station’s two-armed Dextre robot, assisted by astronauts on spacewalks, swapped out aging nickel-hydrogen batteries for the upgraded units. Nine of the old batteries were installed on the HTV cargo pallet before its release from the station’s robotic arm.

Study finds that we could lose science if publishers go bankrupt

Academic publishing, Science, Science communications / /

Need backups —

A scan of archives shows that lots of scientific papers aren’t backed up.

–

A set of library shelves with lots of volumes stacked on them.

Back when scientific publications came in paper form, libraries played a key role in ensuring that knowledge didn’t disappear. Copies went out to so many libraries that any failure—a publisher going bankrupt, a library getting closed—wouldn’t put us at risk of losing information. But, as with anything else, scientific content has gone digital, which has changed what’s involved with preservation.

Organizations have devised systems that should provide options for preserving digital material. But, according to a recently published survey, lots of digital documents aren’t consistently showing up in the archives that are meant to preserve it. And that puts us at risk of losing academic research—including science paid for with taxpayer money.

Tracking down references

The work was done by Martin Eve, a developer at Crossref. That’s the organization that organizes the DOI system, which provides a permanent pointer toward digital documents, including almost every scientific publication. If updates are done properly, a DOI will always resolve to a document, even if that document gets shifted to a new URL.

But it also has a way of handling documents disappearing from their expected location, as might happen if a publisher went bankrupt. There are a set of what’s called “dark archives” that the public doesn’t have access to, but should contain copies of anything that’s had a DOI assigned. If anything goes wrong with a DOI, it should trigger the dark archives to open access, and the DOI updated to point to the copy in the dark archive.

For that to work, however, copies of everything published have to be in the archives. So Eve decided to check whether that’s the case.

Using the Crossref database, Eve got a list of over 7 million DOIs and then checked whether the documents could be found in archives. He included well-known ones, like the Internet Archive at archive.org, as well as some dedicated to academic works, like LOCKSS (Lots of Copies Keeps Stuff Safe) and CLOCKSS (Controlled Lots of Copies Keeps Stuff Safe).

Not well-preserved

The results were… not great.

When Eve broke down the results by publisher, less than 1 percent of the 204 publishers had put the majority of their content into multiple archives. (The cutoff was 75 percent of their content in three or more archives.) Fewer than 10 percent had put more than half their content in at least two archives. And a full third seemed to be doing no organized archiving at all.

At the individual publication level, under 60 percent were present in at least one archive, and over a quarter didn’t appear to be in any of the archives at all. (Another 14 percent were published too recently to have been archived or had incomplete records.)

The good news is that large academic publishers appear to be reasonably good about getting things into archives; most of the unarchived issues stem from smaller publishers.

Eve acknowledges that the study has limits, primarily in that there may be additional archives he hasn’t checked. There are some prominent dark archives that he didn’t have access to, as well as things like Sci-hub, which violates copyright in order to make material from for-profit publishers available to the public. Finally, individual publishers may have their own archiving system in place that could keep publications from disappearing.

Should we be worried?

The risk here is that, ultimately, we may lose access to some academic research. As Eve phrases it, knowledge gets expanded because we’re able to build upon a foundation of facts that we can trace back through a chain of references. If we start losing those links, then the foundation gets shakier. Archiving comes with its own set of challenges: It costs money, it has to be organized, consistent means of accessing the archived material need to be established, and so on.

But, to an extent, we’re failing at the first step. “An important point to make,” Eve writes, “is that there is no consensus over who should be responsible for archiving scholarship in the digital age.”

A somewhat related issue is ensuring that people can find the archived material—the issue that DOIs were designed to solve. In many cases, the authors of the manuscript place copies in places like the arXiv/bioRxiv, or the NIH’s PubMed Centra (this sort of archiving is increasingly being made a requirement by funding bodies). The problem here is that the archived copies may not include the DOI that’s meant to ensure it can be located. That doesn’t mean it can’t be identified through other means, but it definitely makes finding the right document much more difficult.

Put differently, if you can’t find a paper or can’t be certain you’re looking at the right version of it, it can be just as bad as not having a copy of the paper at all.

None of this is to say that we’ve already lost important research documents. But Eve’s paper serves a valuable function by highlighting that the risk is real. We’re well into the era where print copies of journals are irrelevant to most academics, and digital-only academic journals have proliferated. It’s long past time for us to have clear standards in place to ensure that digital versions of research have the endurance that print works have enjoyed.

The Matrix Revolutions —

At the heart of AI, matrix math has just seen its biggest boost “in more than a decade.”

–

Futuristic huge technology tunnel and binary data.

Enlarge / When you do math on a computer, you fly through a numerical tunnel like this—figuratively, of course.

Computer scientists have discovered a new way to multiply large matrices faster than ever before by eliminating a previously unknown inefficiency, reports Quanta Magazine. This could eventually accelerate AI models like ChatGPT, which rely heavily on matrix multiplication to function. The findings, presented in two recent papers, have led to what is reported to be the biggest improvement in matrix multiplication efficiency in over a decade.

Multiplying two rectangular number arrays, known as matrix multiplication, plays a crucial role in today’s AI models, including speech and image recognition, chatbots from every major vendor, AI image generators, and video synthesis models like Sora. Beyond AI, matrix math is so important to modern computing (think image processing and data compression) that even slight gains in efficiency could lead to computational and power savings.

Graphics processing units (GPUs) excel in handling matrix multiplication tasks because of their ability to process many calculations at once. They break down large matrix problems into smaller segments and solve them concurrently using an algorithm.

Perfecting that algorithm has been the key to breakthroughs in matrix multiplication efficiency over the past century—even before computers entered the picture. In October 2022, we covered a new technique discovered by a Google DeepMind AI model called AlphaTensor, focusing on practical algorithmic improvements for specific matrix sizes, such as 4×4 matrices.

By contrast, the new research, conducted by Ran Duan and Renfei Zhou of Tsinghua University, Hongxun Wu of the University of California, Berkeley, and by Virginia Vassilevska Williams, Yinzhan Xu, and Zixuan Xu of the Massachusetts Institute of Technology (in a second paper), seeks theoretical enhancements by aiming to lower the complexity exponent, ω, for a broad efficiency gain across all sizes of matrices. Instead of finding immediate, practical solutions like AlphaTensor, the new technique addresses foundational improvements that could transform the efficiency of matrix multiplication on a more general scale.

Approaching the ideal value

The traditional method for multiplying two n-by-n matrices requires n³ separate multiplications. However, the new technique, which improves upon the “laser method” introduced by Volker Strassen in 1986, has reduced the upper bound of the exponent (denoted as the aforementioned ω), bringing it closer to the ideal value of 2, which represents the theoretical minimum number of operations needed.

The traditional way of multiplying two grids full of numbers could require doing the math up to 27 times for a grid that’s 3×3. But with these advancements, the process is accelerated by significantly reducing the multiplication steps required. The effort minimizes the operations to slightly over twice the size of one side of the grid squared, adjusted by a factor of 2.371552. This is a big deal because it nearly achieves the optimal efficiency of doubling the square’s dimensions, which is the fastest we could ever hope to do it.

Here’s a brief recap of events. In 2020, Josh Alman and Williams introduced a significant improvement in matrix multiplication efficiency by establishing a new upper bound for ω at approximately 2.3728596. In November 2023, Duan and Zhou revealed a method that addressed an inefficiency within the laser method, setting a new upper bound for ω at approximately 2.371866. The achievement marked the most substantial progress in the field since 2010. But just two months later, Williams and her team published a second paper that detailed optimizations that reduced the upper bound for ω to 2.371552.

The 2023 breakthrough stemmed from the discovery of a “hidden loss” in the laser method, where useful blocks of data were unintentionally discarded. In the context of matrix multiplication, “blocks” refer to smaller segments that a large matrix is divided into for easier processing, and “block labeling” is the technique of categorizing these segments to identify which ones to keep and which to discard, optimizing the multiplication process for speed and efficiency. By modifying the way the laser method labels blocks, the researchers were able to reduce waste and improve efficiency significantly.

While the reduction of the omega constant might appear minor at first glance—reducing the 2020 record value by 0.0013076—the cumulative work of Duan, Zhou, and Williams represents the most substantial progress in the field observed since 2010.

“This is a major technical breakthrough,” said William Kuszmaul, a theoretical computer scientist at Harvard University, as quoted by Quanta Magazine. “It is the biggest improvement in matrix multiplication we’ve seen in more than a decade.”

While further progress is expected, there are limitations to the current approach. Researchers believe that understanding the problem more deeply will lead to the development of even better algorithms. As Zhou stated in the Quanta report, “People are still in the very early stages of understanding this age-old problem.”

So what are the practical applications? For AI models, a reduction in computational steps for matrix math could translate into faster training times and more efficient execution of tasks. It could enable more complex models to be trained more quickly, potentially leading to advancements in AI capabilities and the development of more sophisticated AI applications. Additionally, efficiency improvement could make AI technologies more accessible by lowering the computational power and energy consumption required for these tasks. That would also reduce AI’s environmental impact.

The exact impact on the speed of AI models depends on the specific architecture of the AI system and how heavily its tasks rely on matrix multiplication. Advancements in algorithmic efficiency often need to be coupled with hardware optimizations to fully realize potential speed gains. But still, as improvements in algorithmic techniques add up over time, AI will get faster.

AMD stops certifying monitors, TVs under 144 Hz for FreeSync

60 Hz is so 2015 —

120 Hz is good enough for consoles, but not for FreeSync.

AMD announced this week that it has ceased FreeSync certification for monitors or TVs whose maximum refresh rates are under 144 Hz. Previously, FreeSync monitors and TVs could have refresh rates as low as 60 Hz, allowing for screens with lower price tags and ones not targeted at serious gaming to carry the variable refresh-rate technology.

AMD also boosted the refresh-rate requirements for its higher AdaptiveSync tiers, FreeSync Premium and FreeSync Premium Pro, from 120 Hz to 200 Hz.

Here are the new minimum refresh-rate requirements for FreeSync, which haven’t changed for laptops.

Laptops Monitors and TVs
FreeSync Max refresh rate: 40-60 Hz < 3440 Horizontal resolution:

Max refresh rate: ≥ 144 Hz
FreeSync Premium Max refresh rate: ≥ 120 Hz < 3440 Horizontal resolution:

Max refresh rate: ≥ 200 Hz≥ 3440 Horizontal resolution:

Max refresh rate: ≥ 120 Hz
FreeSync Premium Pro FreeSync Premium requirements, plus FreeSync support with HDR FreeSync Premium requirements, plus FreeSync support with HDR

AMD will continue supporting already-certified FreeSync displays even if they don’t meet the above requirements.

Interestingly, AMD’s minimum refresh-rate requirements for TVs go beyond 120 Hz, which many premium TVs currently max out at, due to the current-generation Xbox and PlayStation supporting max refresh rates of 120 frames per second (FPS).

Announcing the changes this week in a blog post, Oguzhan Andic, AMD FreeSync and Radeon product marketing manager, claimed that the changes were necessary, noting that 60 Hz is no longer “considered great for gaming.” Andic wrote that the majority of gaming monitors are 144 Hz or higher, compared to in 2015, when FreeSync debuted, and even 120 Hz was “a rarity.”

Since 2015, refresh rates have climbed ever higher, with the latest sports targeting competitive players hitting 500 Hz, with display stakeholders showing no signs of ending the push for more speed. Meanwhile, FreeSync cemented itself as the more accessible flavor of Adaptive Sync than Nvidia’s G-Sync, which for a long time required specific hardware to run, elevating the costs of supporting products.

AMD’s announcement didn’t address requirements for refresh-rate ranges. Hopefully, OEMs will continue making FreeSync displays, especially monitors, that can still fight screen tears when framerates drop to the double digits.

The changes should also elevate the future price of entry for a monitor or TV with FreeSync TV. Sometimes the inclusion of FreeSync served as a differentiator for people seeking an affordable display and who occasionally do some light gaming or enjoy other media with fast-paced video playback. FreeSync committing itself to 144 Hz and faster screens could help the certification be aligned more with serious gaming.

Meanwhile, there is still hope for future, slower screens to get certification for variable refresh rates. In 2022, the Video Electronics Standards Association (VESA) released its MediaSync Display for video playback and AdaptiveSync for gaming, certifications that have minimum refresh-rate requirements of 60 Hz. VESA developed the lengthy detailed certifications with its dozens of members, including AMD (a display could be MediaSync/AdaptiveSync and/or FreeSync and/or G-Sync certified). In addition to trying to appeal to core gamers, it’s possible that AMD also sees the VESA certifications as more appropriate for slower displays.

In the majority of cases, the excessive amounts led to only minimal side effects.

Federal regulators have long decried drug-containing products that appeal to kids—like nicotine-containing e-cigarette products with fruity and dessert-themed flavors or edible cannabis products sold to look exactly like name-brand candies.

But a less-expected candy-like product is sending thousands of kids to emergency departments in the US in recent years: melatonin, particularly in gummy form. According to a new report from researchers at the Centers for Disease Control and Prevention, use of the over-the-counter sleep-aid supplement has skyrocketed in recent years—and so have calls to poison control centers and visits to emergency departments.

Melatonin, a neurohormone that regulates the sleep-wake cycle, has become very popular for self-managing conditions like sleep disorders and jet lag—even in children. Use of melatonin in adults rose from 0.4 percent in 1999–2000 to 2.1 percent in 2017–2018. But the more people have these tempting, often candy-like supplements in their homes, the more risk that children will get ahold of them unsupervised. Indeed, the rise in use led to a 530 percent increase in poison control center calls and a 420 percent increase in emergency department visits for accidental melatonin ingestion in infants and kids between 2009 and 2020.

And the problem is ongoing. In the new study, researchers estimate that between 2019 and 2022, nearly 11,000 kids went to the emergency department after accidentally gulping down melatonin supplements. Nearly all the cases involved a solid form of melatonin, with about 47 percent identified specifically as gummies and 49 percent listed as an unspecified sold form, likely to include gummies. These melatonin-based emergency visits made up 7 percent of all emergency visits by infants and kids who ingested medications unsupervised.

The candy-like appeal of melatonin products seems evident in the ages of kids rushed to emergency departments. Most emergency department visits for unsupervised medicine exposures are in infants and toddlers ages 1 to 2, but for melatonin-related visits, half were ages 3 to 5. The researchers noted that among the emergency visits with documentation, about three-quarters of the melatonin products involved came out of bottles, suggesting that the young kids managed to open the bottles themselves or that the bottles weren’t properly closed. Manufacturers are not required to use child-resistant packaging on melatonin supplements.

Luckily, most of the cases had only mild to no effects. Still, about 6.5 percent of the cases—a little over 700 children—were hospitalized from their melatonin binge. A 2022 study led by researchers in Michigan found that among poison control center calls for children consuming melatonin, the reported symptoms involved gastrointestinal, cardiovascular, or central nervous systems. For children who are given supervised doses of melatonin to improve sleep, known side effects include drowsiness, increased bedwetting or urination in the evening, headache, dizziness, and agitation.

According to the National Center for Complementary and Integrative Health—part of the National Institutes of Health—supervised use of melatonin in children appears to be safe for short-term use. But there’s simply not much data on use in children, and the long-term effects of regular use or acute exposures are unknown. The NCCIH cautions: “Because melatonin is a hormone, it’s possible that melatonin supplements could affect hormonal development, including puberty, menstrual cycles, and overproduction of the hormone prolactin, but we don’t know for sure.”

For now, the authors of the new study say the data “highlights the continued need to educate parents and other caregivers about the importance of keeping all medications and supplements (including gummies) out of children’s reach and sight.”

GM starts selling Chevy Blazer EVs again, cuts prices up to $6,250

Bad software, charging problems led Chevy to stop selling the Blazer EV in December.

The Chevrolet Blazer EV is back on sale today, more than three months after the automaker took its newest electric vehicle off the market due to a litany of software problems. It has also cut Blazer EV prices, and the company says that the EV now qualifies for the full $7,500 IRS clean vehicle tax credit.

The Blazer EV was the first Chevrolet-badged EV using General Motors’ new Ultium battery platform. Introduced at CES in 2022, Chevrolet actually started delivering the first Blazer EVs last August. But not very many of them—by the end of the year, only 463 Blazer EVs had found homes.

Ars drove the Blazer EV in December and came away unconvinced. On the road, it suffered from lots of NVH, and we ran into software bugs with the Ultifi infotainment system. We weren’t the only ones to experience problems—charging bugs left another journalist stranded on a road trip with a Blazer EV that refused to charge.

Three days later, GM issued a stop-sale order for the car.

Now, the Blazer EV is on sale again and with what Chevrolet is calling “significant software updates.” Some of these are to the UI, but those charging problems should be solved now as well.

The other problem with the Blazer EV, beyond quality issues, was its rather high price. The promised $44,995 version was ditched before the car was launched; instead, the cheapest Blazer EV on sale was the $56,715 all-wheel drive LT, and at $60,215 the all-wheel drive Blazer EV RS was more expensive than the closely related Cadillac Lyriq.

To help tempt customers back into the showroom, Chevrolet has also given the Blazer EV a hefty price cut. Now, the Blazer EV LT costs $50,195, $6,520 less than at launch. The Blazer EV RS got $5,620 cheaper and now starts at $56,175.

Google says the AI-focused Pixel 8 can’t run its latest smartphone AI models

Google, Tech / /

we’re all trying to find the guy who did this —

Gemini Nano can’t run on the smaller Pixel 8 due to mysterious “hardware limitations.”

–

The bigger Pixel 8 Pro gets the latest AI features. The smaller model does not.

Google

If you believe Google’s marketing hype, AI in a phone is really, really important, the best AI is Google’s, and the best place to get that AI is Google’s flagship smartphone, the Pixel 8. We’re five months removed from the launch of the Pixel 8, and that doesn’t seem like a justifiable position anymore: Google says its latest AI models can’t run on the Pixel 8.

Google dropped that news in a Mobile World Congress wrap-up video that was spotted by Mishaal Rahman. At the end of the show in a Q&A session, Googler Terence Zhang, a member of the Gemini-on-Android team, said “[Gemini] Nano will not be coming to the Pixel 8 because of some hardware limitations. It’s currently on the Pixel 8 Pro and very recently available on the Samsung S24 family. It’ll be coming to more high-end devices in the near future.”

That is a wild statement. Gemini is Google’s latest AI model, and it made a big deal of the launch last month. Gemini comes in a few different sizes, and the smallest “Nano” size is specifically designed to run on smartphones as a much-hyped “on-device AI.” The Pixel 8 and Pixel 8 Pro are Google’s flagship smartphones. Google designed the phone and the chip and the AI model and somehow can’t make these things play nice together?

Adding to the weirdness is that Gemini Nano can run on the Pixel 8 Pro but not the smaller Pixel 8 due to “hardware limitations.” What limitations would those be, exactly? The two phones have the exact same Google Tensor SoC. They run the same software. The main differences between the two phones are screen size (6.7 inches versus 6.2), battery size, a different camera loadout, and 8GB of RAM versus 12GB. RAM is the only known difference you can point to that could create a processing limitation, but Gemini Nano also runs on the Galaxy S24 series, where the base model has 8GB of RAM. RAM being the issue would mean Samsung phones are somehow more RAM efficient than Pixel phones, which is hard to believe. If the Pixel 8 Pro Tensor 3 and Pixel 8 Tensor 3 are different somehow, that’s not on the spec sheet.

Five months ago at the Pixel 8 launch event, Google painted a very different picture of the Pixel 8 series: “I’m excited to introduce you to the next evolution of AI in your hand, Google Pixel 8 Pro and Google Pixel 8. Our latest phones bring together so many technologies from across Google. They’re the first phones to use our latest Google Tensor chip. They include the very best Android experience, first-of-its-kind camera experiences, and the latest AI advancements from Google.” Both devices feature the custom Google Tensor 3 SoC that Google claimed was “designed specifically to bring Google’s AI breakthroughs directly to Pixel users and show the world what’s possible.” This custom Google AI-focused design was supposed to deliver “unbelievably helpful experiences that no other phone can.”

Google's

Google

When you launch two phones at once, it’s always hard to distinguish what the actual differences between the two models are. Sometimes, the devices get talked about in the plural, while other times “Pixel 8” is used to represent both devices. Sometimes, the more expensive device is singularly mentioned for no reason other than it’s the more expensive flagship. Between the hour-long presentation and private press pre-briefing that Ars was a part of, “What’s the difference” became a pretty well-worn question that was expected to be answered clearly. Usually, the go-to delineator here is the spec sheet, which is expected to spell out in clear language what you’re actually buying. The Google Store has a compare page where you can directly pit the Pixel 8 and Pixel 8 Pro against each other, and nothing spells out a difference in AI processing capabilities or a difference in the Tensor chips.

In the case of the Pixel 8 and Pixel 8 Pro, Google wasn’t clear enough in its communication at launch. Today, though, re-watching the launch presentation with the new knowledge that there is some dramatic difference in AI processing capabilities, you can pick up some language like talk of the “Pixel 8 Pro’s on-device LLM” that you could now interpret as a declaration of exclusive AI capabilities for the Pro model, but that wasn’t clear at the time.

As a consumer, it’s hard not to feel misled, and it’s embarrassing for Google, but to practically care about this, you’d need to know what the heck “Gemini Nano” actually does and why you should care about it. That’s a hard question to answer. Google has a page up here detailing some of the features Gemini Nano powers on the Pixel 8 Pro, but a feature could also be powered by different models on different devices. For what it’s worth, the rundown lists a “summarize” feature for the Google Recorder app and “smart reply” in Gboard. Plenty of Google apps already have a “smart reply” feature without Gemini Nano. Third-party developers can also plug into the onboard Gemini Nano model for their apps, but it’s hard to imagine anyone doing that with such limited device support.

The other option is to just forget about doing all of this AI stuff on-device and just do it in the cloud. As a great example of this, none of this Gemini Nano stuff has anything to do with the Google Gemini Chatbot, which all runs in the cloud. A big question is what this will mean for the smaller Google Pixel 8 going forward. Google promised seven years of OS updates for the new Pixels, and to already be stripping down features due to “hardware limitations” after five months is a disappointment.

Apple has agreed to reinstate Epic Game’s Swedish iOS developer account just days after Epic publicized Apple’s decision to rescind that account. The move once again paves the way for Epic’s plans to release a sideloadable version of the Epic Games Store and Fortnite on iOS devices in Europe.

“Following conversations with Epic, they have committed to follow the rules, including our DMA policies,” Apple said in a statement provided to Ars Technica. “As a result, Epic Sweden AB has been permitted to re-sign the developer agreement and accepted into the Apple Developer Program.”

Apple’s new statement is in stark contrast to its position earlier this week when it cited “Epic’s egregious breach of its contractual obligations to Apple” as a reason why it couldn’t trust Epic’s commitments to stand by any new developer agreement. In correspondence with Epic shared by the Fortnite maker Wednesday, Apple executive Phil Schiller put an even finer point on it:

Your colorful criticism of our [Digital Markets Act] compliance plan, coupled with Epic’s past practice of intentionally violating contractual provisions with which it disagrees, strongly suggest that Epic Sweden does not intend to follow the rules… Developers who are unable or unwilling to keep their promises can’t continue to participate in the Developer Program.

A new regulatory world

Apple’s quick turnaround comes just a day after the European Commission said it was opening an investigation into Apple’s conduct under the new Digital Markets Act and other potentially applicable European regulations. That investigation could have entailed hefty fines of up to “10 percent of the company’s total worldwide turnover” if Apple was found to be in violation.

“We have the DMA coming into compliance [Thursday], so the demand of compliance is… listen, you need to be able to carry another app store, for instance, and you cannot put in place a fee structure that sort of disables the benefits of the DMA for all the market participants,” European Commission Executive Vice President Margrethe Vestager told Bloomberg TV Tuesday.

In an update on its official blog, Epic linked Apple’s decision to “public backlash for retaliation” and said the whole affair “sends a strong signal to developers that the European Commission will act swiftly to enforce the Digital Markets Act and hold gatekeepers accountable. We are moving forward as planned to launch the Epic Games Store and bring Fortnite back to iOS in Europe. Onward!”

In a social media post celebrating Apple’s move, Epic CEO Tim Sweeney said that “the DMA just had its first major victory” and called the move “a big win for European rule of law, for the European Commission, and for the freedom of developers worldwide to speak up.”

Apple’s apparent retreat on the issue preempts what would have likely been a lengthy legal and public relations battle between the two corporate giants, much like the one resulting from Epic’s 2020 decision to violate Apple’s developer agreement by adding third-party payment options to Fortnite on iOS. But that battle, which played out primarily in a series of US courts, differed in many particulars from the new conflict that was developing under the new enforcement regime surrounding Europe’s DMA rules.

Epic said last month that it plans to launch the Epic Games Store on iOS sometime in 2024.

THE PLOT THICKENS —

Midnight Blizzard is now using stolen secrets in follow-on attacks against customers.

Microsoft says Kremlin-backed hackers accessed its source and internal systems

Microsoft said that Kremlin-backed hackers who breached its corporate network in January have expanded their access since then in follow-on attacks that are targeting customers and have compromised the company’s source code and internal systems.

The intrusion, which the software company disclosed in January, was carried out by Midnight Blizzard, the name used to track a hacking group widely attributed to the Federal Security Service, a Russian intelligence agency. Microsoft said at the time that Midnight Blizzard gained access to senior executives’ email accounts for months after first exploiting a weak password in a test device connected to the company’s network. Microsoft went on to say it had no indication any of its source code or production systems had been compromised.

Secrets sent in email

In an update published Friday, Microsoft said it uncovered evidence that Midnight Blizzard had used the information it gained initially to further push into its network and compromise both source code and internal systems. The hacking group—which is tracked under multiple other names, including APT29, Cozy Bear, CozyDuke, The Dukes, Dark Halo, and Nobelium—has been using the proprietary information in follow-on attacks, not only against Microsoft but also its customers.

“In recent weeks, we have seen evidence that Midnight Blizzard is using information initially exfiltrated from our corporate email systems to gain, or attempt to gain, unauthorized access,” Friday’s update said. “This has included access to some of the company’s source code repositories and internal systems. To date we have found no evidence that Microsoft-hosted customer-facing systems have been compromised.

In January’s disclosure, Microsoft said Midnight Blizzard used a password-spraying attack to compromise a “legacy non-production test tenant account” on the company’s network. Those details meant that the account hadn’t been removed once it was decommissioned, a practice that’s considered essential for securing networks. The details also meant that the password used to log in to the account was weak enough to be guessed by sending a steady stream of credentials harvested from previous breaches—a technique known as password spraying.

In the months since, Microsoft said Friday, Midnight Blizzard has been exploiting the information it obtained earlier in follow-on attacks that have stepped up an already high rate of password spraying.

Unprecedented global threat

Microsoft officials wrote:

It is apparent that Midnight Blizzard is attempting to use secrets of different types it has found. Some of these secrets were shared between customers and Microsoft in email, and as we discover them in our exfiltrated email, we have been and are reaching out to these customers to assist them in taking mitigating measures. Midnight Blizzard has increased the volume of some aspects of the attack, such as password sprays, by as much as 10-fold in February, compared to the already large volume we saw in January 2024.

Midnight Blizzard’s ongoing attack is characterized by a sustained, significant commitment of the threat actor’s resources, coordination, and focus. It may be using the information it has obtained to accumulate a picture of areas to attack and enhance its ability to do so. This reflects what has become more broadly an unprecedented global threat landscape, especially in terms of sophisticated nation-state attacks.

The attack began in November and wasn’t detected until January. Microsoft said then that the breach allowed Midnight Blizzard to monitor the email accounts of senior executives and security personnel, raising the possibility that the group was able to read sensitive communications for as long as three months. Microsoft said one motivation for the attack was for Midnight Blizzard to learn what the company knew about the threat group. Microsoft said at the time and reiterated again Friday that it had no evidence the hackers gained access to customer-facing systems.

Midnight Blizzard is among the most prolific APTs, short for advanced persistent threats, the term used for skilled, well-funded hacking groups that are mostly backed by nation-states. The group was behind the SolarWinds supply-chain attack that led to the hacking of the US Departments of Energy, Commerce, Treasury, and Homeland Security and about 100 private-sector companies.

Last week, the UK National Cyber Security Centre (NCSC) and international partners warned that in recent months, the threat group has expanded its activity to target aviation, education, law enforcement, local and state councils, government financial departments, and military organizations.

After accusing team boss of “inappropriate behavior,” female F1 employee suspended.

Formula 1 has been embroiled in a scandal as its 2024 season gets underway. As Ars detailed on Monday, the team principal for Red Bull Racing, Christian Horner, was investigated by his organization for what was described as “controlling and inappropriate behavior” toward a female member of his staff. Now, we’ve learned that the staff member has been suspended with pay by the F1 team.

A spokesperson for the team told The Guardian that Red Bull was unable to comment on an internal matter.

Last week, Red Bull issued a statement about the dismissal of the grievance, stating that the complainant has a right of appeal but that it “is confident that the investigation has been fair, rigorous, and impartial.”

“The investigation report is confidential and contains the private information of the parties and third parties who assisted in the investigation, and therefore we will not be commenting further out of respect for all concerned,” the statement said. “Red Bull will continue striving to meet the highest workplace standards.”

Today, Horner faced the F1 media in a press conference for F1 team bosses at the Saudi Arabian Grand Prix, which takes place this Saturday. “It has been of great interest in different elements of the media for different reasons,” Horner said, adding, “I think it’s time to draw a line under it. And to focus on what is going on on track.”

Regarding the investigation, Horner said, “We are all bound by the same restrictions. Even if I’d like to talk about it, I can’t. This has been trying in many respects.”

Although Horner was cleared by Red Bull’s internal investigation, an anonymous source leaked WhatsApp screenshots, allegedly between Horner and the now-suspended employee—to hundreds of people in the F1 paddock. That was followed by Jos Verstappen, father of F1 world champion Max Verstappen, telling the media that Horner’s position was untenable.

Verstappen Sr. has denied being behind the leak, which is largely believed to be part of an internal Red Bull power struggle following the death of co-owner Dietrich Mateschitz. Horner has the backing of the Thai family that owns 51 percent of the company, but not the Austrian management of Red Bull GmbH, which has the backing of Mateschitz’s son, who owns the remaining 49 percent.

Others in the paddock have been pressed on their views of the situation. Seven-time world champion Lewis Hamilton told journalists that “it’s a really, really important time for the sport to show and stick to its values, hold ourselves accountable for our actions, and it’s a really, really pivotal moment for the sport in terms of what we project to the world and how it’s handled.”

“And it’s not been handled very well to this point, and I think transparency is really key,” Hamilton continued.

“It highlights some of the issues that we also have within the sport, when we’re talking about diversity and inclusion, that inclusion, making people feel comfortable in this environment, it’s clearly not the case.”

Speaking to Bloomberg, James Vowles, team principal for Williams Racing, said, “I can only control what happens within Williams, and what I can do within that environment is open everyone’s eyes to ‘this is how we have to be,’ because the best ideas don’t come from being a closed group of individuals. It comes from diversity.

“These allegations are allegations,” Vowles said. “I’m afraid I don’t have any understanding of what is behind them and the significance of what has happened. All I can say is that should this ever happen in our regard, we’ll be entirely supportive in terms of fixing it and making sure we have a culture that is accepting of everyone.”

But not every voice from the paddock has been as supportive. RB driver Daniel Ricciardo, who has become a fan favorite as a result of Netflix’s Drive to Survive, told the media he hoped the situation would just go away. “You want things to be smoother than they are, of course,” Ricciardo said. “Right now, there is a lot of noise and distraction, no doubt. Look, the way they performed last week… for them to be able to still focus on business on track, that is also a big strength of theirs. Hopefully, these things start to slowly go away, and they could just focus on being a racing team.”

As optics go, these are bad, particularly as the news of the employee’s suspension emerged on International Women’s Day and on the first day of the season for F1 Academy, a series for young women drivers to get their foot on the single-seater racing ladder. French phenom Doriane Pin was fastest in F1 Academy testing, followed by Britain’s Abby Pulling and the American Lia Block, daughter of Ken Block, the late star of the Gymkhana drifting videos.

Don’t trade the secrets dept. —

Linwei Ding faces four counts of trade secret theft, each with a potential 10-year prison term.

On Wednesday, authorities arrested former Google software engineer Linwei Ding in Newark, California, on charges of stealing AI trade secrets from the company. The US Department of Justice alleges that Ding, a Chinese national, committed the theft while secretly working with two China-based companies.

According to the indictment, Ding, who was hired by Google in 2019 and had access to confidential information about the company’s data centers, began uploading hundreds of files into a personal Google Cloud account two years ago.

The trade secrets Ding allegedly copied contained “detailed information about the architecture and functionality of GPU and TPU chips and systems, the software that allows the chips to communicate and execute tasks, and the software that orchestrates thousands of chips into a supercomputer capable of executing at the cutting edge of machine learning and AI technology,” according to the indictment.

Shortly after the alleged theft began, Ding was offered the position of chief technology officer at an early-stage technology company in China that touted its use of AI technology. The company offered him a monthly salary of about $14,800, plus an annual bonus and company stock. Ding reportedly traveled to China, participated in investor meetings, and sought to raise capital for the company.

Investigators reviewed surveillance camera footage that showed another employee scanning Ding’s name badge at the entrance of the building where Ding worked at Google, making him look like he was working from his office when he was actually traveling.

Ding also founded and served as the chief executive of a separate China-based startup company that aspired to train “large AI models powered by supercomputing chips,” according to the indictment. Prosecutors say Ding did not disclose either affiliation to Google, which described him as a junior employee. He resigned from Google on December 26 of last year.

The FBI served a search warrant at Ding’s home in January, seizing his electronic devices and later executing an additional warrant for the contents of his personal accounts. Authorities found more than 500 unique files of confidential information that Ding allegedly stole from Google. The indictment says that Ding copied the files into the Apple Notes application on his Google-issued Apple MacBook, then converted the Apple Notes into PDF files and uploaded them to an external account to evade detection.

“We have strict safeguards to prevent the theft of our confidential commercial information and trade secrets,” Google spokesperson José Castañeda told Ars Technica. “After an investigation, we found that this employee stole numerous documents, and we quickly referred the case to law enforcement. We are grateful to the FBI for helping protect our information and will continue cooperating with them closely.”

Attorney General Merrick Garland announced the case against the 38-year-old at an American Bar Association conference in San Francisco. Ding faces four counts of federal trade secret theft, each carrying a potential sentence of up to 10 years in prison.

Epic Games

European Union regulators are investigating whether Apple’s recent revocation of an Epic Games iOS developer account puts the iPhone-maker in violation of the Digital Markets Act and other rules in the continent. If Apple is found in violation, the European Commission could impose significant fines as part of its effort to put some force behind its sweeping tech regulations.

“We have requested further explanations on this from Apple under the DMA (Digital Markets Act),” a European Commission spokesperson told Reuters late Thursday. “We are also evaluating whether Apple’s actions [regarding Epic Games] raise doubts on their compliance with the DSA (Digital Services Act) and the P2B (Platform to Business Regulation), given the links between the developer program membership and the App store as designated VLOP (very large online platform).”

More than just the DMA

Apple’s plans for what Epic calls “malicious compliance” under the DMA, which goes into effect today, have gotten plenty of attention in recent months. But the European Commission’s statement suggests its investigation could encompass other regulations as well.

The Digital Services Act, which went into effect in Europe last year, is mainly focused on transparency in algorithmic recommendations and “systemic risks” in platforms promoting misinformation. But the act also stipulates that platform moderation, including account suspension or termination, must be enforced “in a diligent, objective, and proportionate manner (emphasis added).” Whether Epic’s apparently indefinite ban from iOS development fits that proportionality standard is something the EU is seemingly interested in investigating.

The EU’s platform-to-business trading regulations, meanwhile, require major platforms like Apple to meet certain guidelines for transparency in their communications with other businesses. That includes detailed instructions for “specific preliminary steps” that have to be taken before a large platform terminates a business account.

“Listen, you need to be able to carry another app store…”

Earlier this week, the European Commission imposed a significant $2 billion fine on Apple over the company’s treatment of competing music subscription services on its devices. That penalty, which Apple is appealing, could be seen as a sign that European regulators plan to enforce violations of their major tech regulations with more than a slap on the wrist. The available penalties for DMA violations can run up to “10 percent of the company’s total worldwide turnover” for a first offense.

“The fine is there to punish past behavior and of course to be a deterrent for it not to be repeated,” European Commission Executive Vice President Margrethe Vestager told Bloomberg TV Tuesday. “We have the DMA coming into compliance [Thursday], so the demand of compliance is… listen, you need to be able to carry another app store, for instance, and you cannot put in place a fee structure that sort of disables the benefits of the DMA for all the market participants…”

In a statement Wednesday Apple cited “Epic’s egregious breach of its contractual obligations to Apple” in its decision to rescind Epic’s Swedish iOS developer account. Apple also cited US legal cases establishing its “right to terminate ‘any or all of Epic Games’ wholly owned subsidiaries, affiliates, and/or other entities under Epic Games’ control at any time and at Apple’s sole discretion.'”

Epic says it has provided a “good faith” promise to abide by Apple’s terms for creating a competing App Store in the EU and that it is being punished for criticizing the iPhone maker publicly. “Apple is retaliating against Epic for speaking out against Apple’s unfair and illegal practices, just as they’ve done to other developers time and time again,” the company said in a statement Wednesday.
