If you’re like me, you or a loved one has struggled through the process of gaining pre-approval for the medical care that your physician has recommended. Personal stories abound regarding the tribulations of patients as they go through hoops to get their health insurer to pay for certain prescription medications, medical procedures, and more.

When used judiciously, this process—known as prior authorization—serves as a check on overuse and spending on services or technologies for which there are less costly alternatives. But a large majority of physicians voice concerns about care delays, which can cause patients to abandon recommended treatments while waiting for the insurance company to verify their eligibility and confirm that the treatment is, indeed, medically necessary. Patients who are denied care may submit an appeal, but that requires more time.

AI might be able to help. With its ability to efficiently sort through vast reams of information, artificial intelligence could theoretically expedite approval of unambiguously allowable claims, thereby reducing care delays. However, AI-driven prior authorization is facing resistance, as it may increase wrongful denials of health insurance coverage. A 2025 American Medical Association survey of physicians revealed significant concern about the application of AI tools, with 61 percent of doctors worrying that AI will exacerbate denials of what they deem are necessary treatments.

As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.

The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.

FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million.

The Space Development Agency was established in 2019 to help speed up the deployment of US military space systems by sidestepping the Pentagon's traditional sluggish bureaucracy.

Seven years later, SDA is finally launching its first batches of operational satellites, just as the Pentagon plans to shutter the semi-autonomous agency and fold it back into the Space Force's procurement pipeline, newly reorganized under several program acquisition executives in a bid to streamline weapons buying.

SDA's fate is not a surprise, and lawmakers in both houses of Congress have backed the agency's closure in drafts of this year's National Defense Authorization Act.

On Wednesday, Defense Secretary Pete Hegseth made the startling announcement that the US military would begin requiring all active duty and reserve personnel aged 30 and older to undergo mandatory screening for testosterone deficiency. The screenings will take place during yearly health assessments. Those under age 30 can also get screened on request.

In a short video posted on social media, Hegseth explained to the military community that the screenings and possible subsequent treatments are intended to "optimize your performance, your resilience, and your long-term health." While saying that the initiative wasn't about "artificial enhancement" and that members could decline treatment, Hegseth claimed that the testing and potential treatment was for "restoring and optimizing" capabilities, protecting "longevity," and "ensuring you have the biological foundation required to sustain the fight."

But will testosterone screening and treatment actually "optimize" our "warfighters"? Will it help most of them live longer? Should everyone else get screened and treated, too?

Federal officials on Friday announced that shredded iceberg lettuce imported from Mexico and served at Taco Bell restaurants in five states is a source of Cyclospora, the foodborne parasite causing the nationwide surge in cases of explosive, watery diarrhea. The five states are Indiana, Kentucky, Michigan, Ohio, and West Virginia.

A traceback investigation by the Centers for Disease Control and Prevention and the Food and Drug Administration identified a single supplier in Mexico as the source of iceberg lettuce for Taco Bell restaurants where sick people reported eating. While federal authorities did not name the supplier, sources told the Washington Post that it is Taylor Farms.

Taylor Farms was also implicated in a 2024 multi-state E. coli outbreak linked to contaminated onions served at McDonald's and other fast-food restaurants. At the time, FDA inspectors found multiple violations at a Taylor Farms facility in Colorado.

Last month, we reported on a troubling incident at the annual meeting of the American Diabetes Association (ADA) in New Orleans. On June 5, five leading scientists were ousted for handing out copies of an editorial, published in the journal Diabetes Care (an ADA journal) in April, sharply criticizing the Trump administration’s ongoing attacks on scientific research. There was a public outcry and (eventually) a personal apology from the ADA's CEO for the heavy-handed response, but it seems the organization has not yet learned its lesson.

The deputy editors of Diabetes Care have posted an editorial and seven accompanying opinion articles to a preprint server—handily contained in a single PDF file—that they say the ADA has refused to publish. Several troubling new details are included in the articles, including an accusation that ADA leadership knew in advance that members would be handing out copies of the editorial and deliberately set up an ambush by venue security and local police. That decision, in turn, might be due to simmering tensions connected to a session organized the year before.

ADA leadership was provided with the articles in advance of publication with an invitation to simultaneously publish their response.

Everyone seems to be launching and landing rockets these days.

Last week, China joined the club of countries that have launched an orbital mission and brought its booster safely back to Earth, which is just the beginning of public and private ventures in that country aggressively pushing into rocket reuse. Also in Asia, Japan's space agency has been conducting hop tests, and Honda recently performed vertical reuse tests.

In the United States, of course, SpaceX launches and lands reusable rockets every few days. Blue Origin, although its New Glenn booster is temporarily grounded, has also demonstrated the ability to both land and re-launch a large orbital booster. Other US companies, including Stoke Space, Rocket Lab, and Relativity Space, are all making credible progress toward partially or fully reusable rockets.

Fubo prices are going up by $15 per month because it will have some NBCUniversal channels again.

For years, Fubo, a sports-centric vMVPD (virtual multichannel video programming distributor, which lets subscribers watch traditional TV channels live over the Internet), offered NBCUniversal channels. That stopped in November 2025 due to a contract dispute.

With the loss of local NBC affiliates, Telemundo, nine regional sports channels, and 32 national channels, Fubo made the sensible but rare decision to lower subscription prices in December. The Essential plan went from $85 per month to $74 per month. The Pro plan dropped from $85 to $75 per month, and the Elite plan dropped from $95 to $84 per month.

This week, San Francisco’s attorney general, David Chiu, sent cease-and-desist letters, demanding that Apple and Google remove 13 so-called nudification apps from their app stores, Wired reported.

Nudification apps can make it trivially easy to transform ordinary photos of real people into explicit images. The harmful AI tools allow bad actors to remove clothing, change a person’s features, place them in sexualized positions, and swap victims’ faces onto other people’s naked bodies.

Chiu's letter warned that app stores were violating "California’s laws that prohibit supporting services that create deepfake pornography," Wired reported.

Climate change is being driven largely by the greenhouse gases we've pumped into the atmosphere, which trap more of the Sun's energy there. That added energy increases the odds of extreme events: longer, more intense heat waves and droughts, interspersed with excessive precipitation. But these sorts of events have happened in the past—how can we tell if any given weather disaster has been made more likely by the climate?

It's a question with implications for everything from building codes to disaster preparedness. And there's some good news: According to a report released by the US National Academies of Science on Thursday, the field of climate attribution is growing increasingly mature and can answer some questions for us with far greater confidence than it could just a decade ago. The report also notes that there are still important limits and suggests steps to address them.

Overall, this makes it clear that climate attribution is normal, mainstream science. And the fossil fuel industry views that as a problem, as it could make it easier to hold companies liable for damages. This has triggered a backlash that has Republicans in Congress and state governments threatening the National Academies' funding.

The rich and famous who filed into the Kennedy Center’s opera house in December were there to enjoy one of the nation’s most exclusive celebrations of the performing arts: the center’s annual honors gala.

The black-tie event, hosted by President Donald Trump, prioritized tickets to people who donated more than $75,000 to the center. This year, it feted Hollywood icon Sylvester Stallone, the legendary glam rock band Kiss and the Grammy Award-winning disco pioneer Gloria Gaynor.

Among the attendees that evening were two lower-profile government officials whose regulatory decisions had been crucial to the future of the gala’s broadcast sponsor, CBS, and its parent company, Paramount.

When Lucid introduced the Air electric sedan in late 2021, the first Air Dream Edition I tested packed over 1,100 hp (820 kW) and carried a $180,000-plus window sticker. It's easily the most powerful street car I've tested; the only vehicle I've driven with more power was a purebred race car with a third the mass, and it was on a proper track. Its combustion engine was also about 1,000 times louder than the Air, helping to remind us that "combustion" really does mean explosion after explosion.

For Lucid's second act, the company debuted the Gravity electric SUV last year, and I've just tested the 2026 Gravity Touring, which starts at about $82,000 in the US, including the required destination charge.

My test model carried a bevy of options, including a 22-speaker audio system, the Comfort and Convenience package, third-row seating, a Dynamic Handling package (combining rear-wheel steering and three-chamber air suspension), a luxury seating package (bundling Nappa leather and massaging and ventilated front seats), and special metallic paint.

Welcome to Edition 9.03 of the Rocket Report! SpaceX counted down all the way to T-0 on Thursday evening in South Texas before a handful of Raptor engines decided not to light at ignition of the rocket. It is not clear whether the vehicle can be worked on at the pad, or whether Starship will need to be de-stacked before this can occur. In any case, a few days delay beats a significant issue in flight.

As always, we welcome reader submissions, and 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.

Vikram-1 rocket gets a launch date. The debut launch attempt by Skyroot Aerospace of its Vikram-1 rocket is now set for July 18, at 11:30 am local time in India. This will be the first time a commercial rocket developed in India attempts to reach orbit. Designed to carry small satellites weighing up to 350 kg to low-Earth orbit, Vikram-1 is targeting a 450 km orbit at a 60-degree inclination.

SpaceX called off a test flight of its powerful Starship rocket and Super Heavy booster as the countdown clock reached zero Thursday at the company's spaceport in South Texas.

The launch team at Starbase, Texas, just north of the US-Mexico border, aimed to launch the more than 400-foot-tall rocket at 5:45 pm local time (6:45 pm EDT; 22:45 UTC). The countdown proceeded smoothly throughout the day, culminating in the loading of more than 11.5 million pounds of liquid methane and liquid oxygen into the two-stage rocket.

But the computers controlling the countdown called an abort during the Super Heavy booster's engine startup sequence. SpaceX scrubbed the launch attempt, and engineers began preparations to drain the rocket's propellant tanks. Officials did not immediately announce when they plan to try to launch again.

Two nominees for high-profile health roles in the Trump administration faced scrutiny from the Senate health committee Wednesday—and both crashed and burned in their own special ways.

The Senate Committee on Health, Education, Labor, and Pensions (HELP) scrutinized Erica Schwartz, the nominee for director of the Centers for Disease Control and Prevention, and Sean Kaufman, up for the role of assistant secretary for preparedness and response.

Schwartz's assignment

Public health experts were "cautiously optimistic" about Schwartz's nomination. She is well-respected and holds views in line with evidence-based medicine, including being supportive of vaccinations—in contrast to anti-vaccine Health Secretary Robert F. Kennedy Jr., whom she will serve under. She is also highly qualified for the role, with a medical degree, a master's degree in public health, and a law degree. She's had a long career as a Navy Officer and previously held the roles of chief medical officer for the US Coast Guard and deputy surgeon general in the first Trump administration.

The Indian government has fined HP India and its partners a total of 1.4 billion rupees (about $14.4 million) for working with reseller partners in the “cartelization” of computers, ink cartridges, and toner.

The Competition Commission of India (CCI) said this week that it found HP India had colluded with some channel partners to drive up the cost of bids for government contracts for computers, as well as for selling ink cartridges, toner, and other printing supplies, including graphic and digital manufacturing supplies.

It said that HP was aiming to outcompete other OEMs and discourage resellers from selling “counterfeit” ink and toner.

T-Mobile canceled some longtime subscribers' free-line promotions as part of a forced migration to new rate plans, spurring complaints from customers yesterday. T-Mobile admitted the problem and blamed it on technical errors that it is trying to fix.

The forced plan changes were controversial to begin with, particularly as many longtime users are being hit with price hikes of $6 per line. The unexpected loss of free lines for some of those users could raise prices by a much higher amount if the change isn't reversed.

There is good news, though. T-Mobile told Ars today that it was a mistake and that the company is working to fix the problem. Of course, it's not always easy for telecom customers to get the proper resolution even after a company admits to an error publicly. But given T-Mobile's statement today, we hope the firm will fix the problem for all impacted customers with as little hassle as possible.

Europe wasted no time using its landmark Digital Markets Act (DMA) to try to rein in Big Tech. Companies like Apple, Meta, and Google have faced steep fines and orders to modify their business practices since the law came into force in 2024. And the hits keep on coming for Big Tech in Europe. After several months of consideration, the European Commission has announced new DMA measures that will force Google to support interoperability and competition in the European Union, and Google is not happy about it.

The new "specification measures" cover two elements of Google's business: Android phones and search. Both changes could theoretically increase competition and give users more choices, but Google claims they will undermine privacy and security. But as a "gatekeeper" under the DMA, Google has no choice but to comply. As the European Commission points out in its announcement, these decisions are legally binding.

On Android, Google will have to open up access to competing AI platforms. Currently, Google's Gemini gets preferential access to the system. Gemini is preloaded on all Google-certified Android phones and can wake up in response to the "Hey Google" hot word. Google's AI also includes system and app automation features, screen content access, and more.

Facing mounting pressure to acknowledge that Grok can still be used to generate non-consensual sexualized images of adults and minors, xAI filed a lawsuit Tuesday, suing the first user that Elon Musk’s firm has accused of using its chatbot to create illegal content.

The complaint targets Terry Wayne Harwood, who was arrested earlier this year for possession and distribution of child sexual abuse materials (CSAM), the South Carolina attorney’s office announced.

As xAI alleged, the company assisted in that arrest after discovering that Harwood had been using two xAI accounts for months to undress or “nudify” non-sexual images of multiple victims, including a young girl who appeared to be as young as 10.

Thousands of unionized Hyundai auto workers began walking off the job early after negotiations with the South Korean automaker broke down over plans to deploy humanoid robots—the most significant pushback from organized labor so far over the latest wave of robotic automation.

The partial strike at Hyundai’s automotive production complex in the city of Ulsan in South Korea represents “the car industry’s first factory stoppage addressing humanoid robots,” according to The Wall Street Journal. Workers have already ended their day and night shifts two hours early at the world’s largest automotive plant from July 13 through July 15, and plan to start staging four-hour strikes from July 20 to 22 after 15 rounds of negotiations failed to reach an agreement, The Korea Times reported.

Union pushback began as soon as Hyundai Motor Group unveiled the latest version of the Atlas humanoid robot, a two-legged robot that stands at more than 6 feet tall and can lift more than 100 pounds, at the start of this year. Atlas is made by Boston Dynamics, the US robotics company that is about to become a wholly owned subsidiary of Hyundai.

Kalshi is a high-tech prediction market that allows people to "forecast the future" (their term). It is about contracts and information, the company says, making its offerings more like a soybean futures contract than a round of blackjack or a pull on the one-armed bandit.

Still, prediction markets look a lot like betting if you squint, which is why states like New York have tried to regulate them under gambling laws. To head this off, Kalshi has sought federal protection under the Commodity Futures Trading Commission (CFTC). Yes, this means regulation for Kalshi, but it also means the CFTC will sue states like Kentucky, Minnesota, Illinois, and Rhode Island, trying to pre-empt their laws in favor of a single national standard that the CFTC controls.

While this battle plays out, government insiders continue to generate insider trading stories after using their work knowledge to place bets "forecast the future" and make huge sums of money. The classic example, of course, was Gannon Ken Van Dyke, a US soldier who participated in planning the capture of Venezuela's Nicolas Maduro and then made $410,000 from that knowledge on the prediction site Polymarket. Van Dyke was arrested in April.

For year after year, more Americans have bought Toyota RAV4s than anything that isn't a pickup truck. The brand's reputation for solid reliability has kept it ahead of SUVs from other automakers, and the nation's embrace of SUVs and crossovers relegated the poor old Camry to near-bottom of the top 10. For the latest generation—the sixth since 1994—all RAV4s are electrified. Most will use a mix of internal combustion engine and brakes to recharge their hybrid powertrains' traction batteries, like the millions of Priuses out there on the roads. But there's also a plug-in hybrid EV option, with an all-new powertrain with some noticeable improvements compared to the outgoing PHEV.

Just as Toyota's designers and engineers have tried to improve on the previous RAV4 with each successive generation, their counterparts in the powertrain department have similarly been iterating and improving the combination of electric motors and piston engine. Under the hood there's a naturally aspirated 2.5 L four-cylinder engine that operates on the Atkinson-cycle, aided by variable valve timing on both intake and exhaust sides.

The engine, which on its own generates 186 hp (139 kW) and 172 lb-ft (233 Nm), is connected to one of two electric motors under the RAV4's hood, as well as to Toyota's electronically controlled variable ratio transmission.

One of the Russian government’s most elite hacking groups has adopted an attack, known as Clickfix, to compromise devices belonging to sensitive organizations in Ukraine, the latter country’s CERT center is warning.

Clickfix has emerged as an effective attack technique that attackers, primarily financially motivated criminals, began using in the last year or so. Websites under the control of the attackers display a CAPTCHA that requires the visitor to copy a jumble of text and paste it into the terminal. The text contains scripts that, once entered, perform malicious actions, typically by installing malware or exfiltrating sensitive data. Ukraine’s CERT said Wednesday that Sandworm, an advanced hacking unit inside the GRU, Russia’s military intelligence arm, is now using the technique.

"GhettoVibe," "ScoutCurl," and many more

The Clickfix attacks began in the spring and have continued through the summer. The campaign has resulted in the network compromise of at least one organization when a connected device was found to be infected by FreakyPoll, the name of one of Sandworm’s custom malware packages. Ukrainian authorities discovered 10 compromised websites that displayed a PowerShell command as part of a fake CAPTCHA that said it had to be passed to ensure a real human was behind the visiting device’s keyboard.

The widespread introduction of AI-powered coding tools has led to some dramatic splits between those integrating those tools into their workflows and anti-AI absolutists who don't want large language model-generated code anywhere near their projects. When it comes to the Linux kernel, though, creator and top-level maintainer Linus Torvalds said he is "willing to absolutely put my foot down" in support of using AI tools to improve the long-standing open source project.

Writing in a lengthy post on the Linux kernel mailing list this week, Torvalds said that "Linux is not one of those anti-AI projects, and if somebody has issues with that, they can do the open-source thing and fork it. Or just walk away."

The statement came amid a lengthy thread arguing about the use of Sashiko, an "agentic Linux kernel code review system" that its creators claim can, in tests, independently find 53.6 percent of the bugs that would end up being fixed by human coders in later commits. But the tool can also waste maintainers' time by sending "false positive" reports of bugs that don't exist, at a rate Sashiko's maintainers estimate is "well within [the] 20% range."

Most of the gas in the Universe is a mixture of hydrogen and helium. It's thought that the initial atmospheres of most planets also start out that way. However, over billions of years, as planets evolve, the composition of their atmospheres may shift. Hydrogen can react with other chemicals, and both it and helium can be lost to space. Venus, Earth, and Mars are thought to have second atmospheres, with their original hydrogen/helium envelopes having been lost and/or transformed.

The dynamics of loss are complicated. Lighter elements are lost more easily, but hydrogen can be protected by being incorporated into molecules like methane and ammonia. The gravity of the body can help retain some molecules, and a magnetic field can limit radiation's ability to blast material out of the atmosphere. Proximity to a star will matter too, both because of the radiation it produces and because it can heat the atmosphere and expand it to where gravity's influence is less substantial.

Given all these complications, it can be difficult to know what to expect to find on exoplanets. But a study in Wednesday's issue of Nature describes observations of helium being lost from the atmosphere of an exoplanet orbiting the star LHS 1140, about 50 light-years away. Based on the rate at which the helium is being lost, we can infer something about the remaining atmosphere.

OnePlus arrived on the scene in 2014 with brash marketing and a compelling pitch: What if your phone was cheaper and faster? More than a decade later, the market is much different, and so is OnePlus. Confirming months of rumors and speculation, OnePlus has confirmed it's ending phone releases in North America and Europe.

This development has been expected for a while. After a brief period of expansion in the US through deals with T-Mobile and Verizon, OnePlus began visibly shifting its focus to India after the pandemic. OnePlus has also increasingly come under the control of its parent company, Oppo, aligning its device releases and software experience with the larger brand. Still, OnePlus has continued to launch flagship devices in the US and Europe, with the OnePlus 15 going on sale in late 2025. That will be the last OnePlus phone many people see, though.

OnePlus denied rumors of a shutdown earlier this year, but its language was vague and never promised future phone releases. The new statement is also worded gingerly, but the outcome is clear. "As part of the proactive global strategy adjustment, OnePlus has decided to conclude new product rollouts in Europe and North America," the official post reads.

One week ago, three widely respected European news outlets published the results of an investigation into what they described as a "joint plan" by China and Russia to "defeat Elon Musk's Starlink."

The story was the product of a long-running inquiry by The Insider, Der Spiegel, and Le Monde. Reporters at those publications said they reviewed a cache of documents detailing growing military cooperation between China and Russia. The documents covered discussions between the nuclear powers on integrated air and missile defense systems, autonomous "swarm" loitering munitions, next-generation armored vehicles, and military aviation, the report said.

According to the papers, the investigation found evidence of a partnership between China and Russia in the field of space weapons far deeper than either country has acknowledged. One particular focus for China and Russia has been developing strategies to counter SpaceX's Starlink satellite broadband network.

Energy companies are raising money at IPO at their fastest pace this century, taking advantage of investors’ hunt for new ways to bet on the boom in power-intensive AI data centers.

Initial public offerings for energy firms raised $12.6 billion in the first half of this year, according to data firm Dealogic. That marks the highest half-year level since the peak of the dotcom bubble in late 1999 and the highest first-half figure on record. It is well above 2025’s full-year total of $4.3 billion.

The surge in fundraising comes as access to the vast amounts of energy needed to run data centers emerges as a bottleneck in a multi-trillion-dollar AI investment boom.

On Wednesday, the National Transportation Safety Board (NTSB) released preliminary findings verifying Elon Musk’s and Tesla’s claims that a driver involved in a fatal Texas crash that killed a grandmother overrode Full Self Driving in the moments ahead of impact.

Last month, 44-year-old Michael Butler told police that the autopilot feature was engaged at the time of the crash. On X, Musk disputed the claim, writing that Butler must have overridden the feature because “FSD drives slowly through neighborhood streets, and this was a high-speed crash!” Moving to back Musk’s claim, Tesla’s vice president of AI software, Ashok Elluswamy, said that internal data showed “the driver manually overrode self-driving by pressing the accelerator all the way to 100 percent of the accel pedal in this residential area.”

NTSB’s preliminary report, which does not yet determine what caused the crash, confirmed Tesla’s claims. Its probe found that FSD was engaged at the time of the crash, but electronic data showed “the driver manually overrode FSD (Supervised) by pressing the accelerator pedal to 100 percent.”

New navigation satellites in low-Earth orbit could provide 100 times stronger signal strength compared to GPS and other global navigation satellite systems operating from higher orbital altitudes—enabling greater location accuracy within dense cities, under thick foliage, and even inside buildings. Such signals would also likely prove more resilient to interference at a time when commercial flights, maritime shipping, and even various smartphone apps face increasingly widespread disruption from GPS jamming.

That vision may start to take shape when the first six production satellites of California-based Xona Space Systems are scheduled to launch in October 2026, with early service starting in 2027. Once the full constellation of 258 Pulsar satellites has been launched in the following years, Xona claims that customers will be able to accurately pinpoint their locations anywhere on Earth to within several centimeters.

“That added power means that we can get into that indoor environment that GPS can't get to today,” Adrien Perkins, co-founder and VP of engineering at Xona Space Systems, told Ars. “Our higher power allows you to get into those jamming environments a lot further than you would with GPS by itself.”

ROCKVILLE, Maryland—Hundreds of Bethesda Game Studios and Zenimax Online Studios employees and their supporters braved nearly 100° F temperatures to protest sweeping layoffs across Xbox during a lunchtime rally in front of parent company Zenimax's headquarters today. The rally was one of five today organized by Zenimax Workers United and its parent union, the Communication Workers of America, at offices across Texas, California, and Montreal.

Attendees held up signs with messages like "Layoffs... layoffs never change" and "Our players deserve better" as union organizers and employees rallied the crowd with speeches and songs. The overwhelming message was one of solidarity and a willingness to push back against job cuts they say have decimated their development and quality assurance teams.

"It's about us building our movement and making sure that we get seen and we're visible," Bethesda technical producer and union volunteer organizer Nathan Hahn told Ars. "Because we want to make sure that we're not okay with these layoffs and that Xbox knows."

A dried-out felt-tip marker and a snapped-off piece of molded black plastic sold for $857,600 at a Sotheby's auction on Wednesday.

What otherwise might have been worthless bits of trash commanded the highest bids due to where the two items were 57 years ago—lifting off aboard NASA's Apollo 11 spacecraft on humanity's first mission to land astronauts on the Moon. More than flown odds and ends, one was the problem that almost stranded Neil Armstrong and Buzz Aldrin on the lunar surface, and the other was the simple solution to saving the mission.

"Houston, Tranquility. Do you have a way of showing the configuration of the engine arm circuit breaker?" radioed Aldrin to Mission Control after realizing he or Armstrong had inadvertently broken off the top of the circuit breaker switch that would enable their ascent engine to ignite, beginning their trip back to Earth. "The reason I'm asking is because the end of it appears to be broken off. I think we can push it back in again. I'm not sure we could pull it out if we pushed it in, though."

Sheetz, a US convenience store chain, is moving its 838 locations off VMware.

Sheetz has used VMware virtualization across two Dell R440/R450-series servers at each of its locations since 2019. Now it’s migrating 12 to 14 virtual machines (VMs) in each of its stores from VMware vSphere to StorMagic’s SvHCI, “with an additional two VMs to be replaced over the coming months to transition from Windows 10 to Windows 11,” Scott Robertson, infrastructure team manager at Sheetz, told Ars Technica via email. Ultimately, Sheetz will move about 11,000 VMs from Broadcom's virtualization platform. Sheetz is still running the original Dell server hardware.

So far, Sheetz has finished migrating more than 600 stores, averaging 200 per month, according to a company announcement today. Sheetz should be finished with the migration in four months, the announcement said.

This week, the Coalition for Independent Technology Research (CITR) won a key battle in its fight to reverse a visa-restriction policy that the Trump administration had used to attempt to revoke green cards and deport non-US citizens who work on misinformation, disinformation, fact-checking, content moderation, compliance, and trust and safety.

In an opinion published Tuesday, US District Judge James Boasberg granted a preliminary injunction blocking the State Department from enforcing the policy until the CITR’s lawsuit is resolved.

On its face, the policy does not require visa denials or deportations. Instead, it authorizes immigration investigations into individuals suspected of helping foreign adversaries attempt to manipulate public opinion by suppressing US speech.

Jurassic Park, while beloved as a film, has been the subject of snarky memes for the infamous line in which one of the characters declares, "This is a Unix system, I know this!" while using a computer with an unusual 3D file manager interface.

Despite the memes, the film's production team was meticulous in accurately sourcing the right PCs (and adjacent details) for the sets—not too much of a surprise, given writer Michael Crichton's background with computing and his obsessive attention to detail in the book the film is based on.

Right on the heels of Microsoft releasing a record number of security patches, a researcher has published exploit code that can enable low-privilege Windows accounts to make sensitive changes to administrator accounts.

The exploit, which multiple researchers say works, is sending Microsoft scrambling, yet again, to patch a zero-day released by an anonymous researcher who has complained about the software maker’s handling of their bug reports. To date, the pseudonymous NightmareEclypse has published nine such exploits, including Tuesday’s HiveLegacy. The researcher said the proof-of-concept code included in the report was stripped down to prevent attackers from using it maliciously.

A “pretty powerful primitive”

HiveLegacy is an elevation-of-privilege exploit that targets a vulnerability residing in the Windows User Profile Service. It allows users (and with more work likely processes) with limited system rights to compromise an admin user's account by modifying its classes registry hive, a resource that ensures the correct application opens when certain types of files are clicked on in Windows Explorer.

The Federal Communications Commission will vote to repeal the National Television Ownership Rule that is supposed to prevent a single broadcast station owner from reaching more than 39 percent of all TV households in the US. The proposed change sets up a likely court battle over the FCC claim that it has authority to repeal a limit set by Congress.

FCC Chairman Brendan Carr has already treated the rule as more of a suggestion. In March, the Carr FCC granted a waiver allowing Nexstar Media Group to buy Tegna in a deal that let it reach over half of TV households. The Carr FCC argued that Congress gave it authority to modify or waive the rule.

Carr now plans to repeal the 39 percent limit and replace it with a "case-by-case review" of each proposed merger, the chairman announced today in an op-ed published on Breitbart. The change would make it easier for the FCC to pick and choose which station groups get to surpass the limit. Under Carr, this would likely benefit news companies that provide favorable coverage for President Trump.

New Zealand actor Sam Neill, who starred as Dr. Alan Grant in the 1993 blockbuster Jurassic Park and its 2022 sequel, Jurassic World Dominion, died on Monday in Sydney, Australia. He was 78.

While American audiences likely know Neill best for Jurassic Park, he had a long and varied career in film and television. His sheer versatility won him fans around the world. He played the grown Damien in Omen III: The Final Conflict; a Russian officer in The Hunt for Red October; and even made brief cameos (as an actor playing Odin in a theatrical troupe) in Thor: Ragnarok and Thor: Love and Thunder. (The less said about 1997's space horror travesty, Event Horizon, the better, although it has its fans, and Neill made the most of his role.) Yet some of his best performances were in smaller, critically acclaimed independent films such as 1993's Oscar-winning The Piano.

On television, Neill earned his first Golden Globe nomination for the lead role in Reilly, Ace of Spies in the 1980s. He was nominated for both an Emmy and a second Golden Globe for playing the titular Arthurian wizard in the 1998 miniseries Merlin. He played Cardinal Wolsley in The Tudors, and was part of the ensemble cast in the (excellent) 2015 adaptation of Agatha Christie's And Then There Were None. Neill was magnetic as the ruthless CI Major Chester Campbell in Peaky Blinders—an antagonist and romantic rival of Cillian Murphy's Tommy Shelby.

Big changes are coming to Android apps, but they're not the changes Google wanted. The settlement between Google and Epic that aimed to put to rest the companies' long-running antitrust battle is being withdrawn, and that means third-party app stores are coming to the Play Store. Google has confirmed that it will begin distributing rival app stores next week, setting the stage for competing platforms to take a bite out of Google's Android revenue stream.

This case has the potential to upend software distribution on Android, and it's all because of V-Bucks. In 2020, Epic Games was frustrated that it had to pay a 30 percent cut to Apple and Google every time someone bought a bundle of V-Bucks in a mobile version of Fortnite. The publisher added a direct purchase option to the game in violation of both Apple's and Google's rules. Naturally, Fortnite was pulled from the App Store and Google Play, kicking off the antitrust lawsuit that is only now reaching its conclusion.

While Apple suffered little penalty in its Epic case, Google was tripped up by its anti-competitive management of the supposedly open Android ecosystem. Google used its market position to discourage device makers from promoting or pre-loading non-Google app stores and attempted to hide that conduct. The remedies set by Judge James Donato included lower fees, mirroring Google Play apps in other stores, and most vitally, placement of alternative app stores in Google Play.

As rumors continue to swirl about OpenAI's work on a personalized smart speaker and other hardware, the company is today rolling out its first branded device. The $230 Codex Micro is a specialized, RGB-lit mini-keyboard designed to let users monitor and quickly interact with multiple Codex agents with a glance and a few clicks.

The device is described as a "limited-run collaboration" with Work Louder, which already sells a very similar-looking Creator Micro line of customizable square keyboards targeted at creative professionals. The Codex Micro differentiates itself from those mainly through six frosted keys in the top two rows, which offer color-coded live feedback on up to six Codex threads, even when they are not in focus on-screen.

Ideally, those colored keys will cycle from white when a thread is idle to blue when Codex is thinking to green when a task is complete. But the keys can also flash amber when Codex requires feedback or a decision from a human operator and red when a thread encounters an error, letting users know at a glance which of their Codex tasks needs immediate attention. A quick tap on the lit-up button brings up the applicable Codex window on-screen.

Anil Menon, a NASA flight surgeon, felt crushed nine years ago as his hopes and aspirations collapsed around him.

For the fourth time, he had diligently applied to become an astronaut at the US space agency, seeking to fulfill a lifelong dream. Although he made it to the final round, NASA had once again rejected his application at the end of the grueling process.

"I was so sad, and I admitted defeat," Menon said. "I just did not see a pathway forward. So I pretty much, at that point in time, gave up on being an astronaut. I thought there was a zero percent chance."

SpaceX has pinned the bulk of its future value on orbital data centers. Not rockets. Not spacecraft.

Instead, it envisions launching and maintaining a constellation of 1 million satellites capable of generating 120 GW to power tens of millions—and potentially up to 100 million—frontier-class GPUs for data center services.

The company's founder, Elon Musk, revealed plans for this massive constellation months ago, but until recently, the scope of the individual satellites was largely unknown. That changed in June, when Musk and Ian Dahl, director of satellite engineering for SpaceX, spoke in a promotional video about the company's plans to develop the first iteration of an orbital data center, called an AI1 satellite. The video finally provided the company's numbers about the satellite's size and power capabilities.

Forget the sale of the century. The auction house Sotheby’s has geared up for the sale of the epoch. On July 14 it opened live bidding on assorted fossils, but the pièce de résistance is lot 20, a rare 67-million-year-old Tyrannosaurus rex skeleton.

The specimen—dubbed Gus—is billed as one of the largest, most complete T. rexes ever found. Gus is expected to fetch up to $30 million and will go to the highest bidder, whether public museum or private collector. The latter have played an increasingly prominent role in buying fossils, with auction houses, according to paleontologists, contributing to the trend by building hype. But when private collectors swoop in and buy fossils at auction as luxury assets, those pieces of history are effectively lost to science.

By nearly all accounts, Gus is a big deal. In its description, Sotheby’s boasts that the specimen, which was discovered on a ranch in South Dakota, comprises “an incredible 183 fossil bone elements” making it “approximately 61% complete by bone count.” The fossil remains have been mounted in a custom steel armature along with replicas of the missing bones. The result is a reconstructed skeleton posed as if in hot pursuit, its mouth full of dagger teeth ready to tear into prey.

An industry-wide standard Microsoft invented to protect Windows, and later Linux, devices from firmware infections has been trivial to bypass for 13 of its 14 years of existence. The discovery was made by researchers at security firm ESET after identifying 11 firmware images, at least one from 2013, that were known to be defective but remained signed by the software company anyway.

The images are known as shims, which were invented to extend Secure Boot to Linux devices and utility software. Using a technique simple enough to be performed by novice hackers, these old, forgotten shims can be used to completely circumvent the protection, which is embedded into the UEFI (Unified Extensible Firmware Interface) of the device's motherboard. The gaffe is the result of the failure by Microsoft, which oversees the signing of shims, to revoke the publicly available images once vulnerabilities were found in them.

Threat extends to Windows and Linux users

The threat extends to Windows and Linux users alike, since the shim can be installed on devices running both operating systems. From there, an attacker can subvert the mandated chain of digitally signed firmware to install malicious firmware that loads early in the boot process and persists after either the OS is reinstalled or a hard drive is replaced.

The Trump administration on Monday barred US citizens in the Democratic Republic of the Congo from returning home amid an Ebola outbreak that continues to outpace response efforts.

Reuters first reported late Monday that Americans currently in the DRC or those who have recently traveled to the Ebola-stricken country have been put on a "do-not-board" list. They cannot travel back to the US until they have spent 21 days in a third country. The order, taken under a transportation authority known as Title 49, was independently confirmed by Politico on Tuesday.

Both outlets noted that roughly two dozen Americans who had been set to board flights home on Tuesday have already been blocked by the new rule. It remains unclear if the bar also applies to government workers. The Centers for Disease Control and Prevention has at least two dozen employees working in the DRC.

Meta's AI-fueled layoffs of 8,000 employees targeted workers with disabilities and those who took protected medical or family leaves, alleged a lawsuit filed by 26 employees who were selected for termination. Meta used internal AI tools to select employees for layoffs, according to the complaint filed yesterday by 26 "Doe" plaintiffs in US District Court for the Northern District of California.

"Meta did not assemble the termination list through the considered judgment of managers who knew the work. Instead, Meta used a constellation of internal artificial-intelligence systems—including a system referred to internally as 'Metamate,' employee-trained 'second-brain' agents, keystroke- and activity-monitoring data, AI-token-usage dashboards, and algorithmically assisted performance ranking and calibration—to score, rank, and select employees for inclusion on the list," the lawsuit said.

Employees were allegedly graded, among other things, on how much they used Meta's AI tools. "Meta’s internal dashboards classified employees by their stage of adoption of its artificial-intelligence tools, using categories such as 'AI Native,' 'AI First,' and 'AI Enabled,'" the lawsuit said.

For the first time in its history, the US military sent explosive-laden drone boats into combat by attacking an Iranian midget submarine and naval port. The unprecedented use of such kamikaze sea drones by the United States comes nearly a decade after Iranian and Houthi forces first demonstrated such weapons.

The US military shared a video showing three “one-way attack surface drones” exploding after approaching an Iranian midget submarine and ship maintenance facility at Iran’s Bandar Abbas Naval Base on the night of July 12. US Central Command, the US military combat command responsible for Middle East operations, described the strikes in a social media post as the “first time American forces have employed sea drones in combat operations.”

The US drone boats were able to “make a low-speed, uncontested approach” to their targets before exploding, according to USNI News, a news service from the nonprofit US Naval Institute. USNI News also identified one of the targets as an Iranian Ghadir-class midget submarine that was out of the water while being suspended from a gantry.

Scientists at Pennsylvania State University have developed a novel conductive ink that can be painted directly onto the skin in colorful custom designs, turning into a functional electrode for biomonitoring after drying. They described their work in a new paper published in the Proceedings of the National Academy of Sciences (PNAS).

As previously reported, epidermal electronics attached to the skin via temporary tattoos (e-tattoos) have been around for more than a decade. So-called e-tattoos connect to skin without adhesives, are practically unnoticeable, and are typically attached via temporary tattoo, allowing electrical measurements (and other measurements, such as temperature and strain) using ultra-thin polymers with embedded circuit elements.

However, these e-tattoos have their limitations, most notably that they don’t function well on curved and/or hairy surfaces, as well as requiring personalized electrode placement design to cover larger areas, since biosignals are spatially distributed. So scientists have been getting creative. For instance, in 2024, researchers developed special polymer-based conductive inks that can be printed onto a person’s scalp to measure brain waves, even if they have hair. This could one day enable mobile EEG monitoring outside a clinical setting, among other potential applications.

Believe it or not, there was a time when searching the web for images was not possible. Twenty-five years ago, Google launched image search, and it's celebrating by looking back at its biggest visual milestones and refreshing the experience for today's searchers. The celebration also includes expanded AI because that's just how Google rolls in 2026.

Google claims the impetus for image search a quarter-century ago was the green Versace dress Jennifer Lopez wore to the 2000 Grammy Awards. If you were alive at the time, you probably remember the one. Google engineers understood that people searching for the dress didn't want to read about it—they just wanted to see it. The company got to work building image search, launching the first version in July 2001. Twenty-five years later, it's easy to take for granted that you can search for Lopez's green dress or whatever else strikes your fancy.

Currently, going to the Google image search site shows a plain search bar for finding images. It's a refreshingly minimalist interface for the modern web. Even Google's search homepage has a smattering of AI buttons and drop-down menus. That will change when the new Google Images rolls out.
