CUPERTINO, Calif.—We’re a long way from the days when a new iPhone launch just meant one new phone. It shifted to “basically the same phone in two sizes” a decade or so ago, and then to a version of “one lineup of regular phones and one lineup of Pro phones” in 2017 when the iPhone 8 was introduced next to the iPhone X.

But thanks to Apple’s newly introduced iPhone Air, the iPhone 17 lineup gives new phone buyers more choices and trade-offs than they’ve ever had before. Apple’s phones are now available in a spectrum of sizes, weights, speeds, costs, and camera configurations. And while options are great to have, it also means you need to know more about which one to pick.

We’ve gone hands-on with all four of Apple’s new phones, and while more extensive tire-kicking will be required, we can at least try to nail down exactly what kind of person each of these phones is for.

The iPhone Air: Designed for first impressions

There’s no more iPhone mini, and there’s no more iPhone Plus. Now we have an iPhone Air, and it is very much its own thing.

The phone is just over two-thirds the thickness of the iPhone 17, not counting what Apple now calls a “camera plateau” that stretches across the top of the device. It’s 0.22 inches thick and weighs 5.82 ounces, compared to 0.31 inches thick and 6.24 ounces for the iPhone 17. You have to go back to the iPhone 12 (5.78 ounces) to find a full-size iPhone that’s equally light, and that one had a 6.1-inch screen instead of the Air’s more expansive 6.5 inches.

Those don’t look like huge numbers on paper, but when you’re holding the iPhone Air, it does make a substantial difference. While the camera plateau makes it look top-heavy in photos, in reality, it’s light, and that weight is distributed evenly enough that it feels as well-balanced as any of the other iPhones.

The combination of a large-ish screen and light weight created a strong perception of lightness, compared to the iPhone 17 or especially the 7.27-ounce iPhone 17 Pro. I also found that the shiny titanium frame, while a fingerprint magnet, did slide around in my hand less than an aluminum finish.

It’s a phone built to make a strong first impression, whether you’re holding it in an Apple Store or just after an Apple event in a throng of YouTubers who are all throwing elbows so that they can film each individual phone in the hands-on area for 20 minutes apiece. But I do worry that living with the Air would be frustrating in the long haul, specifically because of battery life.

Again, on paper, the numbers Apple is quoting aren’t so far apart. The Air is rated for 27 hours of local video playback, compared to 30 hours for the iPhone 17 and 33 hours for the 17 Pro. But there’s a bigger gap between the numbers for streaming video—22 hours, 27 hours, and 30 hours for the Air, 17, and 17 Pro, respectively—that suggests that any activity that’s actively using the A19 Pro chip or wireless communication is going to drain the battery even faster.

Extrapolate that out two years, when your battery is going to be operating at somewhere between 80 and 90 percent of its original capacity, and a midday charge starts to sound like an inevitability. It’s telling that a thickness-and-weight-increasing external battery accessory was announced in the same breath as the iPhone Air.

Apple’s official acknowledgement of and solution to the battery life issue is a $99 external battery that attaches with MagSafe and charges the phone wirelessly; by Apple’s estimates, it adds roughly 13 hours of runtime on top of what you get from the internal battery.

Doesn’t this defeat the purpose of having an iPhone Air, I hear you asking? Maybe so! But it is at least a better aesthetic match for the iPhone than a chunky third-party brick, and one that’s pretty easy to detach and put away once it has done its job and charged your phone. It has its own separate USB-C port for charging, and a small status light (orange when charging, green when charged) below the Apple logo. The magnetic connection feels sturdy enough that it would be hard to dislodge the battery by accident, but I can’t say that it absolutely couldn’t fall off if you were trying to jam the phone into a pocket or bag and caught the battery on something.

I can say that the iPhone Air probably isn’t for me, because the main things I want from a phone are more battery life and better cameras—I can appreciate something smaller and lighter, but only if it doesn’t compromise that other stuff (I got exactly this kind of upgrade when I jumped from an iPhone 13 Pro to a 15 Pro). That’s fine—when you introduce four phones at once, you don’t need to appeal to every iPhone user with every one of them. But I do wonder whether people will find the Air more convincing than they apparently found the now-departed iPhone mini and iPhone Plus.

The iPhone 17 Pro: Industrial design

If you look at the iPhone Air and you say, “I would actually take a thicker, heavier phone if it had a bigger battery in it,” Apple does already make that phone for you.

The iPhone 17 Pro and Pro Max are more of a design departure from the standard iPhones than they have been in years past, with a distinctive aluminum unibody design and a gigantic camera plateau that replaces the old (and already substantial) three-lens camera bump on the older Pros.

Frankly, I’m not in love with the look of this new design—the aluminum unibody design may be good for durability, but it requires Apple to leave cutouts for other wireless-permeable materials all over the phone’s body, and the result is a two-tone design and a lumpy profile that gives the impression that form follows function on this one. It’s the iPhone equivalent of a polished concrete floor—utilitarian with a trendy veneer. It’s a phone I would be happy to put in a case.

It’s also a bit disappointing that the iPhone 17 Pro continues the Pro phones’ drift back upward in weight—we went from 7.27 ounces to 6.6 ounces from the iPhone 14 Pro to the 15 Pro, then to 7.03 ounces for the 16 Pro, and now right back to 7.27 ounces again. But weight is obviously incidental to other features for many Pro users, and the 17 Pro does at least do cool things that make the increased weight worth it.

The two-toned design, festooned with cutouts, makes the phone look a bit uneven to me. Andrew Cunningham

The one feature that’s easy to wrap your arms around in just a few minutes with the new phone is the upgraded telephoto camera lens, which shifts to a 48MP sensor that enables Apple’s Fusion Camera functionality for telephoto shots for the first time.

If you don’t know, the Fusion Camera system shoots 48MP images and then shrinks them to 12 or 24MP, depending on the phone you’re using—benefiting from the extra detail captured by the 48MP sensor, but keeping photo sizes manageable. To create “optical zoom,” the camera instead crops a native-resolution 12MP image out of the center of that sensor. Quality is reduced somewhat because you lose the benefits of the “pixel binning” process that is used to turn 48MP shots into 12MP or 24MP shots, but you’re still capturing native-resolution images without digital zoom.

Adding that to the telephoto lens for the first time doubles the amount of zoom Apple can offer—it starts at 4x zoom, and can go as high as 8x before you start relying on digital zoom.

We were able to do a bit of shooting with the iPhone 17 Pro’s telephoto camera on the Apple Park campus. Compared to my iPhone 15 Pro and its 3x telephoto lens, the default 4x zoom on the iPhone 17 Pro already gets us a little closer, and the 8x zoom option gets you a lot closer. Zoom all the way in to the orange “hello” and you’ll notice some fuzziness and less-than-tack-sharp details, but for photo prints or sharing digitally the results are impressive.

The extra weight and unfinished look of the iPhone 17 Pro don’t make as good a first impression as the iPhone Air did, but I suspect iPhone Pro users (myself included) will find its larger battery and better camera to be acceptable trade-offs. It will be the easier phone to live with in the long term, in other words.

In between the industrial chic aesthetic of the iPhone 17 Pro and the lightness of the iPhone Air is the regular iPhone, which looks a whole lot like last year’s but might actually get the most noticeable functional upgrades of all three of them.

I’m mainly talking about the ProMotion screen, a 120 Hz OLED display panel with a dynamic refresh rate that can go as low as 1 Hz when the phone isn’t being used. Both ProMotion and the always-on screen feature that it enables have been exclusive to the iPhone Pro for years, even as higher-refresh-rate screens have spread through midrange and budget Android phones.

That extra smoothness is tough to give up once you’ve gotten used to it, and it pairs especially well with the extra motion and bounciness present in Apple’s new Liquid Glass interface. Fitting 6.3 inches of screen into a phone the same size as the 6.1-inch iPhone 16 also heightens the edge-to-edge screen effect. And both ProMotion and the larger screen help put some space between the iPhone 17 and the iPhone 16e, Apple’s current “budget” offering that comes in at just $200 under the price of the regular iPhone.

The other major functional upgrade for people who just walk into the store (or log on to their carrier’s website) and buy the default iPhone is that the base model has been bumped up to 256GB of storage, a reasonably generous allotment that should keep you from having too much trouble with gigantic movie files or years-old gigabytes-large iMessage conversations that you just can’t bear to delete.

This looks like an iPhone, and it feels like an iPhone, and there’s not a lot to convey from a quick hands-on session other than that. In this case, a lack of surprises is a good thing.

Software packages with more than 2 billion weekly downloads hit in supply-chain attack

Hackers planted malicious code in open source software packages with more than 2 billion weekly updates in what is likely to be the world’s biggest supply-chain attack ever.

The attack, which compromised nearly two dozen packages hosted on the npm repository, came to public notice on Monday in social media posts. Around the same time, Josh Junon, a maintainer or co-maintainer of the affected packages, said he had been “pwned” after falling for an email that claimed his account on the platform would be closed unless he logged in to a site and updated his two-factor authentication credentials.

Defeating 2FA the easy way

“Sorry everyone, I should have paid more attention,” Junon, who uses the moniker Qix, wrote. “Not like me; have had a stressful week. Will work to get this cleaned up.”

The unknown attackers behind the account compromise wasted no time capitalizing on it. Within an hour’s time, dozens of open source packages Junon oversees had received updates that added malicious code for transferring cryptocurrency payments to attacker-controlled wallets. With more than 280 lines of code, the addition worked by monitoring infected systems for cryptocurrency transactions and changing the addresses of wallets receiving payments to those controlled by the attacker.

The packages that were compromised, which at last count numbered 20, included some of the most foundational code driving the JavaScript ecosystem. They are used outright and also have thousands of dependents, meaning other npm packages that don’t work unless they are also installed. (npm is the official code repository for JavaScript files.)

“The overlap with such high-profile projects significantly increases the blast radius of this incident,” researchers from security firm Socket said. “By compromising Qix, the attackers gained the ability to push malicious versions of packages that are indirectly depended on by countless applications, libraries, and frameworks.”

The researchers added: “Given the scope and the selection of packages impacted, this appears to be a targeted attack designed to maximize reach across the ecosystem.”

The email message Junon fell for came from an email address at support.npmjs.help, a domain created three days ago to mimic the official npmjs.com used by npm. It said Junon’s account would be closed unless he updated information related to his 2FA—which requires users to present a physical security key or supply a one-time passcode provided by an authenticator app in addition to a password when logging in.

Nobel laureate David Baltimore dead at 87

Nobel Prize-winning molecular biologist and former Caltech president David Baltimore—who found himself at the center of controversial allegations of fraud against a co-author—has died at 87 from cancer complications. He shared the 1975 Nobel Prize in Physiology for his work upending the then-consensus that cellular information flowed only in one direction. Baltimore is survived by his wife of 57 years, biologist Alice Huang, as well as a daughter and granddaughter.

“David Baltimore’s contributions as a virologist, discerning fundamental mechanisms and applying those insights to immunology, to cancer, to AIDS, have transformed biology and medicine,” current Caltech President Thomas F. Rosenbaum said in a statement. “David’s profound influence as a mentor to generations of students and postdocs, his generosity as a colleague, his leadership of great scientific institutions, and his deep involvement in international efforts to define ethical boundaries for biological advances fill out an extraordinary intellectual life.”

Baltimore was born in New York City in 1938. His father worked in the garment industry, and his mother later became a psychologist at the New School and Sarah Lawrence. Young David was academically precocious and decided he wanted to be a scientist after spending a high school summer learning about mouse genetics at the Jackson Laboratory in Maine. He graduated from Swarthmore College and earned his PhD in biology from Rockefeller University in 1964 with a thesis on the study of viruses in animal cells. He joined the Salk Institute in San Diego, married Huang, and moved to MIT in 1982, founding the Whitehead Institute.

Baltimore initially studied viruses like polio and mengovirus that make RNA copies of the RNA genomes to replicate, but later turned his attention to retroviruses, which have enzymes that make DNA copies of viral RNA. He made a major breakthrough when he proved the existence of that viral enzyme, now known as reverse transcriptase. Previously scientists had thought that the flow of information went from DNA to RNA to protein synthesis. Baltimore showed that process could be reversed, ultimately enabling researchers to use disabled retroviruses to insert genes into human DNA to correct genetic diseases.

porsche’s-insanely-clever-hybrid-engine-comes-to-the-911-turbo-s

Porsche’s insanely clever hybrid engine comes to the 911 Turbo S

Today, Porsche debuted a new 911 variant at the IAA Mobility show in Munich, Germany. It’s the most powerful 911 to date, excluding some limited-run models, and may well be the quickest to 60 mph from a standing start, dispatching that dash in just 2.4 seconds. And it’s all thanks to one of the most interesting hybrid powertrains on sale today.

Rather than just bolting an electric motor to an existing 911, Porsche designed an entirely new 3.6 L flat-six engine, taking the opportunity to ditch the belt drive and move some of the ancillaries, which can instead be powered by the car’s 400 V traction battery.

The system debuted in the 911 GTS T-Hybrid, which Ars recently reviewed. For that car, Porsche added a single electric turbocharger, which works like the MGU-H in a Formula 1 car. It spins up almost instantly to 120,000 rpm to eliminate throttle lag, but also recaptures excess energy from the spinning turbine and sends that to the 1.9 kWh battery pack.

The result is a turbocharged engine that has a remarkable throttle response that’s more like an EV, with no perceptible lag between initial tip-in and power being delivered to the wheels.

For the 2026 911 Turbo S, there are a pair of these electric turbochargers. And like the GTS, you’ll find a 53 hp (40 kW), 110 lb-ft (150 Nm) permanent synchronous motor inside the eight-speed dual clutch transmission. Total output is a heady 701 hp (523 kW) and 590 lb-ft (800 Nm), which is sufficient to cut the 0–60 mph (0–98 km/h) time to 2.4 seconds. 124 mph (200 km/h) takes just 8.4 seconds, half a second less than the 2025 Turbo S.

Warner Bros. sues Midjourney to stop AI knockoffs of Batman, Scooby-Doo


AI would’ve gotten away with it too…

Warner Bros. case builds on arguments raised in a Disney/Universal lawsuit.

Warner Bros. hit Midjourney with a lawsuit Thursday, crafting a complaint that strives to shoot down defenses that the AI company has already raised in a similar lawsuit filed by Disney and Universal Studios earlier this year.

The big film studios have alleged that Midjourney profits off image generation models trained to produce outputs of popular characters. For Disney and Universal, intellectual property rights to pop icons like Darth Vader and the Simpsons were allegedly infringed. And now, the WB complaint defends rights over comic characters like Superman, Wonder Woman, and Batman, as well as characters considered “pillars of pop culture with a lasting impact on generations,” like Scooby-Doo and Bugs Bunny, and modern cartoon characters like Rick and Morty.

“Midjourney brazenly dispenses Warner Bros. Discovery’s intellectual property as if it were its own,” the WB complaint said, accusing Midjourney of allowing subscribers to “pick iconic” copyrighted characters and generate them in “every imaginable scene.”

Planning to seize Midjourney’s profits from allegedly using beloved characters to promote its service, Warner Bros. described Midjourney as “defiant and undeterred” by the Disney/Universal lawsuit. Despite that litigation, WB claimed that Midjourney has recently removed copyright protections in its supposedly shameful ongoing bid for profits. Nothing but a permanent injunction will end Midjourney’s outputs of allegedly “countless infringing images,” WB argued, branding Midjourney’s alleged infringements as “vast, intentional, and unrelenting.”

Examples of closely matching outputs include prompts for “screencaps” showing specific movie frames, a search term that at least one artist, Reid Southen, had optimistically predicted Midjourney would block last year, but it apparently did not.

Here are some examples included in WB’s complaint:

Midjourney’s output for the prompt, “Superman, classic cartoon character, DC comics.”

Midjourney could face devastating financial consequences in a loss. At trial, WB is hoping discovery will show the true extent of Midjourney’s alleged infringement, asking the court for maximum statutory damages, at $150,000 per infringing output. Just 2,000 infringing outputs unearthed could cost Midjourney more than its total revenue for 2024, which was approximately $300 million, the WB complaint said.

Warner Bros. hopes to hobble Midjourney’s best defense

For Midjourney, the WB complaint could potentially hit harder than the Disney/Universal lawsuit. WB’s complaint shows how closely studios are monitoring AI copyright litigation, likely choosing ideal moments to strike when studios feel they can better defend their property. So, while much of WB’s complaint echoes Disney and Universal’s arguments—which Midjourney has already begun defending against—IP attorney Randy McCarthy suggested in statements provided to Ars that WB also looked for seemingly smart ways to potentially overcome some of Midjourney’s best defenses when filing its complaint.

WB likely took note when Midjourney filed its response to the Disney/Universal lawsuit last month, arguing that its system is “trained on billions of publicly available images” and generates images not by retrieving a copy of an image in its database but based on “complex statistical relationships between visual features and words in the text-image pairs are encoded within the model.”

This defense could allow Midjourney to avoid claims that it copied WB images and distributes copies through its models. But hoping to dodge this defense, WB didn’t argue that Midjourney retains copies of its images. Rather, the entertainment giant raised a more nuanced argument that:

Midjourney used software, servers, and other technology to store and fix data associated with Warner Bros. Discovery’s Copyrighted Works in such a manner that those works are thereby embodied in the model, from which Midjourney is then able to generate, reproduce, publicly display, and distribute unlimited “copies” and “derivative works” of Warner Bros. Discovery’s works as defined by the Copyright Act.”

McCarthy noted that WB’s argument pushes the court to at least consider that even though “Midjourney does not store copies of the works in its model,” its system “nonetheless accesses the data relating to the works that are stored by Midjourney’s system.”

“This seems to be a very clever way to counter MJ’s ‘statistical pattern analysis’ arguments,” McCarthy said.

If it’s a winning argument, that could give WB a path to wipe Midjourney’s models. WB argued that each time Midjourney provides a “substantially new” version of its image generator, it “repeats this process.” And that ongoing activity—due to Midjourney’s initial allegedly “massive copying” of WB works—allows Midjourney to “further reproduce, publicly display, publicly perform, and distribute image and video outputs that are identical or virtually identical to Warner Bros. Discovery’s Copyrighted Works in response to simple prompts from subscribers.”

Perhaps further strengthening the WB’s argument, the lawsuit noted that Midjourney promotes allegedly infringing outputs on its 24/7 YouTube channel and appears to have plans to compete with traditional TV and streaming services. Asking the court to block Midjourney’s outputs instead, WB claims it’s already been “substantially and irreparably harmed” and risks further damages if the AI image generator is left unchecked.

As alleged proof that the AI company knows its tool is being used to infringe WB property, WB pointed to Midjourney’s own Discord server and subreddit, where users post outputs depicting WB characters and share tips to help others do the same. They also called out Midjourney’s “Explore” page, which allows users to drop a WB-referencing output into the prompt field to generate similar images.

“It is hard to imagine copyright infringement that is any more willful than what Midjourney is doing here,” the WB complaint said.

WB and Midjourney did not immediately respond to Ars’ request to comment.

Midjourney slammed for promising “fewer blocked jobs”

McCarthy noted that WB’s legal strategy differs in other ways from the arguments Midjourney’s already weighed in the Disney/Universal lawsuit.

The WB complaint also anticipates Midjourney’s likely defense that users are generating infringing outputs, not Midjourney, which could invalidate any charges of direct copyright infringement.

In the Disney/Universal lawsuit, Midjourney argued that courts have recently found that AI tools referencing copyrighted works is “a quintessentially transformative fair use,” accusing studios of trying to censor “an instrument for user expression.” They claim that Midjourney cannot know about infringing outputs unless studios use the company’s DMCA process, while noting that subscribers have “any number of legitimate, noninfringing grounds to create images incorporating characters from popular culture,” including “non-commercial fan art, experimentation and ideation, and social commentary and criticism.”

To avoid losing on that front, the WB complaint doesn’t depend on a ruling that Midjourney directly infringed copyrights. Instead, the complaint “more fully” emphasizes how Midjourney may be “secondarily liable for infringement via contributory, inducement and/or vicarious liability by inducing its users to directly infringe,” McCarthy suggested.

Additionally, WB’s complaint “seems to be emphasizing” that Midjourney “allegedly has the technical means to prevent its system from accepting prompts that directly reference copyrighted characters,” and “that would prevent infringing outputs from being displayed,” McCarthy said.

The complaint noted that Midjourney is in full control of what outputs can be generated. Noting that Midjourney “temporarily refused to ‘animate'” outputs of WB characters after launching video generations, the lawsuit appears to have been filed in response to Midjourney “deliberately” removing those protections and then announcing that subscribers would experience “fewer blocked jobs.”

Together, these arguments “appear to be intended to lead to the inference that Midjourney is willfully enticing its users to infringe,” McCarthy said.

WB’s complaint details simple user prompts that generate allegedly infringing outputs without any need to manipulate the system. The ease of generating popular characters seems to make Midjourney a destination for users frustrated by other AI image generators that make it harder to generate infringing outputs, WB alleged.

On top of that, Midjourney also infringes copyrights by generating WB characters, “even in response to generic prompts like ‘classic comic book superhero battle.'” And while Midjourney has seemingly taken steps to block WB characters from appearing on its “Explore” page, where users can find inspiration for prompts, these guardrails aren’t perfect, but rather “spotty and suspicious,” WB alleged. Supposedly, searches for correctly spelled character names like “Batman” are blocked, but any user who accidentally or intentionally mispells a character’s name like “Batma” can learn an easy way to work around that block.

Additionally, WB alleged, “the outputs often contain extensive nuance and detail, background elements, costumes, and accessories beyond what was specified in the prompt.” And every time that Midjourney outputs an allegedly infringing image, it “also trains on the outputs it has generated,” the lawsuit noted, creating a never-ending cycle of continually enhanced AI fakes of pop icons.

Midjourney could slow down the cycle and “minimize” these allegedly infringing outputs, if it cannot automatically block them all, WB suggested. But instead, “Midjourney has made a calculated and profit-driven decision to offer zero protection for copyright owners even though Midjourney knows about the breathtaking scope of its piracy and copyright infringement,” WB alleged.

Fearing a supposed scheme to replace WB in the market by stealing its best-known characters, WB accused Midjourney of willfully allowing WB characters to be generated in order to “generate more money for Midjourney” to potentially compete in streaming markets.

Midjourney will remove protections “on a whim”

As Midjourney’s efforts to expand its features escalate, WB claimed that trust is lost. Even if Midjourney takes steps to address rightsholders’ concerns, WB argued, studios must remain watchful of every upgrade, since apparently, “Midjourney can and will remove copyright protection measures on a whim.”

The complaint noted that Midjourney just this week announced “plans to continue deploying new versions” of its image generator, promising to make it easier to search for and save popular artists’ styles—updating a feature that many artists loathe.

Without an injunction, Midjourney’s alleged infringement could interfere with WB’s licensing opportunities for its content, while “illegally and unfairly” diverting customers who buy WB products like posters, wall art, prints, and coloring books, the complaint said.

Perhaps Midjourney’s strongest defense could be efforts to prove that WB benefits from its image generator. In the Disney/Universal lawsuit, Midjourney pointed out that studios “benefit from generative AI models,” claiming that “many dozens of Midjourney subscribers are associated with” Disney and Universal corporate email addresses. If WB corporate email addresses are found among subscribers, Midjourney could claim that WB is trying to “have it both ways” by “seeking to profit” from AI tools while preventing Midjourney and its subscribers from doing the same.

McCarthy suggested it’s too soon to say how the WB battle will play out, but Midjourney’s response will reveal how it intends to shift tactics to avoid courts potentially picking apart its defense of its training data, while keeping any blame for copyright-infringing outputs squarely on users.

“As with the Disney/Universal lawsuit, we need to wait to see how Midjourney answers these latest allegations,” McCarthy said. “It is definitely an interesting development that will have widespread implications for many sectors of our society.”

RFK Jr. says COVID shots still available to all as cancer patients denied access

Here are some key moments from today’s hearing:

Untrustworthy

With the fallout ongoing from the abrupt ouster of CDC Director Susan Monarez last week, many senators focused on what led to her downfall. In a Wall Street Journal op-ed published two hours before the hearing, Monarez confirmed media reports that she had been fired by Kennedy for refusing to rubber-stamp changes to CDC vaccine guidance based on recommendations from Kennedy’s hand-selected advisors.

“I was told to preapprove the recommendations of a vaccine advisory panel newly filled with people who have publicly expressed antivaccine rhetoric,” Monarez wrote in the op-ed. She said she refused, insisting that the panel’s recommendations be “rigorously and scientifically reviewed before being accepted or rejected.”

In today’s hearing, Senators directly confronted Kennedy with that statement from the op-ed. Kennedy repeatedly said that she is lying and that he never directed her to preapprove vaccine recommendations. Instead, he claims, he told her to resign after he asked her directly if she was a trustworthy person, and she replied, ‘No.”

After several exchanges about this with other senators, Bernie Sanders (I-Vt.) picked it apart further, saying:

“Are you telling us that the former head of CDC went to you, you asked her, ‘Are you a trustworthy person?’ And she said, ‘No, I am not a trustworthy person,'” Sanders asked.

“She didn’t say ‘No, I’m not a trustworthy person,'” Kennedy replied. “She said, ‘No.’ I’m giving a quote.”

After that, Sen. Thom Tillis (R-NC), who seemed skeptical of Kennedy’s arguments generally, pointed out the absurdity of the claim, quoting Kennedy’s previous praise of Monarez. “I don’t see how you go—over four weeks—from a public health expert with ‘unimpeachable scientific credentials,’ a longtime champion of MAHA values, caring and compassionate and brilliant microbiologists, and four weeks later fire her,” Tillis said.  “As somebody who advised executives on hiring strategies, number one, I would suggest in the interview you ask ’em if they’re truthful rather than four weeks after we took the time of the US Senate to confirm the person.”

Sextortion with a twist: Spyware takes webcam pics of users watching porn

“How you use this program is your responsibility,” the page reads. “I will not be held accountable for any illegal activities. Nor do i give a shit how u use it.”

In the hacking campaigns Proofpoint analyzed, cybercriminals attempted to trick users into downloading and installing Stealerium as an attachment or a web link, luring victims with typical bait like a fake payment or invoice. The emails targeted victims inside companies in the hospitality industry, as well as in education and finance, though Proofpoint notes that users outside of companies were also likely targeted but wouldn’t be seen by its monitoring tools.

Once it’s installed, Stealerium is designed to steal a wide variety of data and send it to the hacker via services like Telegram, Discord, or the SMTP protocol in some variants of the spyware, all of which is relatively standard in infostealers. The researchers were more surprised to see the automated sextortion feature, which monitors browser URLs for a list of pornography-related terms such as “sex” and “porn,” which can be customized by the hacker and trigger simultaneous image captures from the user’s webcam and browser. Proofpoint notes that it hasn’t identified any specific victims of that sextortion function, but suggests that the existence of the feature means it has likely been used.

More hands-on sextortion methods are a common blackmail tactic among cybercriminals, and scam campaigns in which hackers claim to have obtained webcam pics of victims looking at pornography have also plagued inboxes in recent years—including some that even try to bolster their credibility with pictures of the victim’s home pulled from Google Maps. But actual, automated webcam pics of users browsing porn is “pretty much unheard of,” says Proofpoint researcher Kyle Cucci. The only similar known example, he says, was a malware campaign that targeted French-speaking users in 2019, discovered by the Slovakian cybersecurity firm ESET.

The pivot to targeting individual users with automated sextortion features may be part of a larger trend of some cybercriminals—particularly lower-tier groups—turning away from high-visibility, large-scale ransomware campaigns and botnets that tend to attract the attention of law enforcement, says Proofpoint’s Larson.

“For a hacker, it’s not like you’re taking down a multimillion-dollar company that is going to make waves and have a lot of follow-on impacts,” Larson says, contrasting the sextortion tactics to ransomware operations that attempt to extort seven-figure sums from companies. “They’re trying to monetize people one at a time. And maybe people who might be ashamed about reporting something like this.”

Philips introduces budget-friendly Hue bulbs as part of major lineup overhaul

The standard Hue bulbs are also getting an upgrade. The new models can dim to as low as 0.2 percent (compared to 2 percent for the Essential bulbs), and Philips claims they can produce the full range of visible color temperatures (from 1,000 to 20,000 K, compared to the 2,200 to 6,500 K range of the Essential bulbs).

The next-most-important addition to the ecosystem is probably the new Hue Bridge Pro, the Hue ecosystem’s first new bridge accessory in a decade. In addition to being faster, the new $99 bridge supports “150+ lights” and “50+ accessories,” at least triple the number supported by the previous Bridge (which is still sticking around at $66 as a lower-cost accessory for smaller setups). Users with multiple Hue bridges will eventually be able to replace them all with a single Bridge Pro, but Hueblog reports that this capability won’t be available until “later this year.”

Other new Hue products include indoor and outdoor strip lights, including cheaper models under the new Essential brand umbrella; Festavia-branded outdoor string lights; and a $170 Hue Secure video doorbell. The new hub and most of the new bulbs are being launched in North America starting today, but the doorbell won’t launch until October, and many of the strip and string lights will be released in November or December. Signify’s press release has specific pricing and availability information for all the accessories.

Audi design finds its minimalist groove again with Concept C

Fans of the TT rejoice—there’s a new Audi two-seater on the way. The German automaker just unveiled Concept C, a stylish and minimalist sports car that marks the start of a new styling philosophy and, hopefully, a return to the bold designs that brought it so much success.

There are design cues and links back through Audi’s history, but this is no pastiche of a retro design as we might have seen from J Mays. Rather, Audi’s design team under Chief Creative Officer Massimo Frascella says that the design influences include one of the pre-war Silver Arrows racing cars, the 1936 Auto Union Type C—Audi being one of the four brands that combined to form Auto Union.

The design is deceptively large—bigger than a TT or even an R8. Aud

The slats that cover the Concept C’s rear bring to mind the cooling louvres at the rear of the Type C, necessary to let the heat generated by its monstrous V16 engine to escape the rear engine bay. But I also see some of the streamlined Rennlimousine in the Concept C’s slab sides.

It’s a much simpler design than the TT concept from 1995, which manages to look almost fussy in its details compared to the Concept C. But the way the air intakes are formed underneath the headlights reminds me a lot of the Bentley Hunaudieres, a mid-engined concept from 1999.

OTC nasal spray seemed to cut COVID infections by 67% in mid-sized trial

COVID context

Like all trials, there are limitations. As mentioned, the number of infections here is small—the impressive efficacy numbers could potentially vanish in a larger trial with more infections. And, while the trial had a high-quality design, it was undertaken in just one location in Germany and mostly involved healthy white women between the ages of 20 and 46, so the findings are not generalizable. The study was also funded by a pharmaceutical company that makes an azelastine nasal spray (though not the one that is sold over the counter in the US).

Still, with the previous studies, the trial offers some hope that this accessible nasal spray could be used as a viral prophylactic for respiratory seasons in the future. And the results land at a time when access to COVID-19 vaccines—which have firmly proven to be safe and highly effective—has been severely restricted in the US by health secretary and anti-vaccine activist Robert F. Kennedy Jr.

As it stands now, it appears that only people ages 65 and over, and those at higher risk of COVID-19 will have access to the shots this year, though some aspects of that access are murky, including how people will prove they’re at high risk. For healthy children, teens, and adults under 65, there may be no access or extremely limited access. That includes groups that medical experts recommend get vaccinated, namely healthy pregnant people and children ages 6 months to 23 months, both of which are considered at high risk from COVID-19 by medical experts, but not federal guidance under Kennedy. Experts also recommend access for healthy people who have contact with vulnerable people, such as cancer doctors, people who live with immunocompromised family members, and people who work in nursing homes.

With limited vaccine access and the normal slew of respiratory viruses on the horizon, a simple nasal spray is an appealing addition to the defenses. The main side effects are fairly minor, including bitter taste in the mouth, nosebleeds, and tiredness.

Delete, Delete, Delete: How FCC Republicans are killing rules faster than ever


FCC speeds up rule-cutting, giving public as little as 10 days to file objections.

The Federal Communications Commission’s Republican chairman is eliminating regulations at breakneck speed by using a process that cuts dozens of rules at a time while giving the public only 10 or 20 days to review each proposal and submit objections.

Chairman Brendan Carr started his “Delete, Delete, Delete” rule-cutting initiative in March and later announced he’d be using the Direct Final Rule (DFR) mechanism to eliminate regulations without a full public-comment period. Direct Final Rule is just one of several mechanisms the FCC is using in the Delete, Delete, Delete initiative. But despite the seeming obscurity of regulations deleted under Direct Final Rule so far, many observers are concerned that the process could easily be abused to eliminate more significant rules that protect consumers.

On July 24, the FCC removed what it called “11 outdated and useless rule provisions” related to telegraphs, rabbit-ear broadcast receivers, and phone booths. The FCC said the 11 provisions consist of “39 regulatory burdens, 7,194 words, and 16 pages.”

The FCC eliminated these rules without the “prior notice and comment” period typically used to comply with the US Administrative Procedure Act (APA), with the FCC finding that it had “good cause” to skip that step. The FCC said it would allow comment for 10 days and that rule eliminations would take effect automatically after the 10-day period unless the FCC concluded that it received “significant adverse comments.”

On August 7, the FCC again used Direct Final Rule to eliminate 98 rules and requirements imposed on broadcasters. This time, the FCC allowed 20 days for comment. But it maintained its stance that the rules would be deleted automatically at the end of the period if no “significant” comments were received.

By contrast, FCC rulemakings usually allow 30 days for initial comments and another 15 days for reply comments. The FCC then considers the comments, responds to the major issues raised, and drafts a final proposal that is put up for a commission vote. This process, which takes months and gives both the public and commissioners more opportunity to consider the changes, can apply both to the creation of new rules and the elimination of existing ones.

FCC’s lone Democrat warns of “Trojan horse”

Telecom companies want the FCC to eliminate rules quickly. As we’ve previously written, AT&T submitted comments to the Delete, Delete, Delete docket urging the agency to eliminate rules that can result in financial penalties “without the delay imposed by notice-and-comment proceeding.”

Carr’s use of Direct Final Rule has drawn criticism from advocacy groups, local governments that could be affected by rule changes, and the FCC’s only Democratic commissioner. Anna Gomez, the lone FCC Democrat, told Ars in a phone interview that the rapid rule-cutting method “could be a Trojan horse because what we did, or what the commission did, is it adopted a process without public comment to eliminate any rule it finds to be outdated and, crucially, unwarranted. We don’t define what either of those terms mean, which therefore could lead to a situation that’s ripe for abuse.”

Gomez said she’d “be concerned if we eliminated rules that are meant to protect or inform consumers, or to promote competition, such as the broadband labels. This commission seems to have entirely lost its focus on consumers.”

Gomez told us that she doesn’t think a 10-day comment period is ever appropriate and that Carr seems to be trying “to meet some kind of arbitrary rule reduction quota.” If the rules being eliminated are truly obsolete, “then what’s the rush?” she asked. “If we don’t give sufficient time for public comment, then what happens when we make a mistake? What happens when we eliminate rules and it turns out, in fact, that these rules were important to keep? That’s why we give the public due process to comment on when we adopt rules and when we eliminate rules.”

Gomez hasn’t objected to the specific rules deleted under this process so far, but she spoke out against the method used by Carr both times Direct Final Rule method was used. “I told the chairman that I could support initiating a proceeding to look at how a Direct Final Rule process could be used going forward and including a Notice of Proposed Rulemaking proposing to eliminate the rules the draft order purports to eliminate today. That offer was declined,” she said in her dissenting statement in the July vote.

Gomez said that rules originally adopted under a notice-and-comment process should not be eliminated “without seeking public comment on appropriate processes and guardrails.” She added that the “order does not limit the Direct Final Rule process to elimination of rules that are objectively obsolete with a clear definition of how that will be applied, asserting instead authority to remove rules that are ‘outdated or unwarranted.'”

Local governments object

Carr argued that the Administrative Procedure Act “gives the commission the authority to fast-track the elimination of rules that inarguably fail to serve the public interest. Using this authority, the Commission can forgo the usual prior notice and public comment period before repealing the rules for these bygone regulations.”

Carr justified the deletions by saying that “outdated and unnecessary regulations from Washington often derail efforts to build high-speed networks and infrastructure across the country.” It’s not clear why the specific rule deletions were needed to accelerate broadband deployment, though. As Carr said, the FCC’s first use of Direct Finale Rule targeted regulations for “telegraph services, rabbit-ear broadcast receivers, and telephone booths—technologies that were considered outdated decades ago.”

Carr’s interpretation of the Administrative Procedure Act is wrong, said an August 6 filing submitted by local governments in Maryland, Massachusetts, the District of Columbia, Oregon, Virginia, California, New York, and Texas. Direct Final Rule “is intended for extremely simple, non-substantive decisions,” and the FCC process “is insufficient to ensure that future Commission decisions will fall within the good cause exception of the Administrative Procedure Act,” the filing said.

Local governments argued that “the new procedure is itself a substantive decision” and should be subject to a full notice-and-comment rulemaking. “The procedure adopted by the Commission makes it almost inevitable that the Commission will adopt rule changes outside of any APA exceptions,” the filing said.

The FCC could face court challenges. Gerard Lavery Lederer, a lawyer for the local government coalition, told Ars, “we fully anticipate that Chairman Carr and the FCC’s general counsel will take our concerns seriously.” But he also said local governments are worried about the FCC adopting industry proposals that “violate local government rights as preserved by Congress in the [Communications] Act” or that have “5th Amendment takings implications and/or 10th Amendment overreach issues.”

Is that tech really “obsolete”?

At least some rules targeted for deletion, like regulations on equipment used by radio and TV broadcast stations, may seem too arcane to care about. But a coalition of 22 public interest, civil rights, labor, and digital rights groups argued in a July 17 letter to Carr that some of the rule deletions could harm vulnerable populations and that the shortened comment period wasn’t long enough to determine the impact.

“For example, the Commission has targeted rules relating to calling cards and telephone booths in the draft Order as ‘obsolete,'” the letter said. “However, calling cards and pay phones remain important technologies for rural areas, immigrant communities, the unhoused, and others without reliable access to modern communications services. The impact on these communities is not clear and will not likely be clear in the short time provided for comment.”

The letter also said the FCC’s new procedure “would effectively eliminate any hope for timely judicial review of elimination of a rule on delegated authority.” Actions taken via delegated authority are handled by FCC bureaus without a vote of the commission.

So far, Carr has held commission votes for his Direct Final Rule actions rather than letting FCC bureau issue orders themselves. But in the July order, the FCC said its bureaus and offices have previously adopted or repealed rules without notice and comment and “reaffirm[ed] that all Bureaus and Offices may continue to take such actions in situations that are exempt from the APA’s notice-and-comment requirements.”

“This is about pushing boundaries”

The advocacy groups’ letter said that delegating authority to bureaus “makes judicial review virtually impossible, even though the order goes into effect immediately.” Parties impacted by actions made on delegated authority can’t go straight to the courts and must instead “file an application for review with the Commission as a prerequisite to any petition for judicial review,” the letter said. The groups argued that “a Chairman that does not wish to permit judicial review of elimination of a rule through DFR may order a bureau to remove the rule, then simply refuse to take action on the application for review.”

The letter was signed by Public Knowledge; Asian Americans Advancing Justice-AAJC; the Benton Institute for Broadband & Society; the Center for Digital Democracy; Common Sense Media; the Communications Workers of America; the Electronic Privacy Information Center; HTTP; LGBT Tech; the Media Access Project; MediaJustice; the Multicultural Media, Telecom and Internet Council; the National Action Network; NBJC; the National Council of Negro Women; the National Digital Inclusion Alliance; the National Hispanic Media Coalition; the National Urban League; New America’s Open Technology Institute (OTI); The Leadership Conference on Civil and Human Rights; the United Church of Christ Media Justice Ministry; and UnidosUS.

Harold Feld, senior VP of consumer advocacy group Public Knowledge, told Ars that the FCC “has a long record of thinking that things are obsolete and then discovering when they run an actual proceeding that there are people still using these things.” Feld is worried that the Direct Final Rule process could be used to eliminate consumer protections that apply to old phone networks when they are replaced by either fiber or wireless service.

“I certainly think that this is about pushing boundaries,” Feld said. When there’s a full notice-and-comment period, the FCC has to “actually address every argument made” before eliminating a rule. When the FCC provides less explanation of a decision, that “makes it much harder to challenge on appeal,” he said.

“Once you have this tool that lets you just get rid of rules without the need to do a proceeding, without the need to address the comments that are raised in that proceeding… it’s easy to see how this ramps up and how hard it is for people to stay constantly alert to look for an announcement where they will then only have 10 days to respond once it gets published,” he said.

What is a “significant” comment?

The FCC says its use of Direct Final Rule is guided by December 2024 recommendations from the Administrative Conference of the United States (ACUS), a government agency. But the FCC didn’t implement Direct Final Rule in the exact way recommended by the ACUS.

The ACUS said its guidance “encourages agencies to use direct final rulemaking, interim final rulemaking, and alternative methods of public engagement to ensure robust public participation even when they rely properly on the good cause exemption.” But the ACUS recommended taking public comment for at least 30 days, while the FCC has used 10- and 20-day periods.

The ACUS also said that agencies should only move ahead with rule deletions “if no significant adverse comments are received.” If such comments are received, the agency “can either withdraw the rule or publish a regular proposed rule that is open for public comment,” the recommendation said.

The FCC said that if it receives comments, “we will evaluate whether they are significant adverse comments that warrant further procedures before changing the rules.” The letter from 22 advocacy groups said it is worried about the leeway the FCC is giving itself in defining whether a comment is adverse and significant:

Although ACUS recommends that the agency revert to standard notice-and-comment rulemaking in the event of a single adverse comment, the draft Order requires multiple adverse comments—at which point the bureau/Commission will consider whether to shift to notice-and-comment rulemaking. If the bureau/Commission decides that adverse comments are not ‘substantive,’ it will explain its determination in a public notice that will not be filed in the Federal Register. The Commission states that it will be guided, but not bound, by the definition of ‘adverse comment’ recommended by ACUS.

Criticism from many corners

TechFreedom, a libertarian-leaning think tank, said it supports Carr’s goals in the “Delete, Delete, Delete” initiative but objected to the Direct Final Rule process. TechFreedom wrote in July comments that “deleting outdated regulations via a Direct Final Rule is unprecedented at the FCC.”

“No such process exists under current FCC rules,” the group said, urging the agency to seek public comment on the process. “If the Commission wishes to establish a new method by which it can eliminate existing regulations without undertaking a full rulemaking proceeding, it should open a docket specific to that subject and seek public comment,” the filing said.

TechFreedom said it is especially important for the FCC to “seek comment as to when the direct final rule procedures should be invoked… What is ‘routine,’ ‘insignificant,’ or ‘inconsequential’ and who is to decide—the Commissioners or the Bureau chiefs?”

The American Library Association and other groups wrote on August 14 that either 10 or 20 days is not long enough for public comment. Moreover, the groups said the two Direct Final Rule actions so far “offer minimal explanation for why the rules are being removed. There is only one sentence describing elimination of many rules and each rule removal is described in a footnote with a parenthetical about the change. It is not enough.”

The Utility Reform Network offered similar objections about the process and said that the FCC declaring technologies to be “obsolete” and markets “outdated” without a detailed explanation “suggests the Commission’s view that these rules are not minor or technical changes but support a larger deregulatory effort that should itself be subject to notice-and-comment rulemaking.”

The National Consumer Law Center and other groups said that “rushing regulatory changes as proposed is likely illegal in many instances, counterproductive, and bad policy,” and that “changes to regulations should be effectuated only through careful, thoughtful, and considered processes.”

We contacted Chairman Carr’s office and did not receive a response.

FCC delegated key decisions to bureaus

Gomez told Ars that Direct Final Rule could serve a purpose “with the right procedures and guardrails in place.” For example, she said the quick rule deletions can be justified for eliminating rules that have become obsolete because of a court reversal or Congressional actions.

“I would argue that we cannot, under the Administrative Procedure Act and the Constitution, simply eliminate rules because we’ve made a judgment call that they are unwarranted,” she said. “That does not meet the good cause exemption to notice-and-comment requirements.”

Gomez also opposes FCC bureaus making significant decisions without a commission vote, which effectively gives Carr more power over the agency’s operations. For example, T-Mobile’s purchase of US Cellular’s wireless operations and Verizon’s purchase of Frontier were approved by the FCC at the Bureau level.

In another instance cited by Gomez, the FCC Media Bureau waived a requirement for broadcast licensees to file their biennial ownership reports for 18 months. “The waiver order, which was done at the bureau level on delegated authority, simply said ‘we find good cause to waive these rules.’ There was no analysis whatsoever,” Gomez said.

Gomez also pointed out that the Carr FCC’s Wireline Competition Bureau delayed implementation of certain price caps on prison phone services. The various bureau-level decisions are a “stretching of the guardrails that we have internally for when things should be done on delegated authority, and when they should be voted by the commission,” Gomez said. “I’m concerned that [Direct Final Rule] is just the next iteration of the same issue.”

Earth models can predict the planet’s future but not their own


One of the world’s foremost climate models now faces funding threats.

In the 1960s, meteorologist Edward Lorenz was running weather simulations on an early computer system when he realized that a small rounding difference led to extremely divergent weather predictions. He later called this idea the butterfly effect to communicate that small changes in initial conditions, like a butterfly flapping its wings in Nepal, could produce wildly different outcomes, like rain in New York.

But better understanding those initial conditions and how the biological world couples with the atmospheric one can provide better predictions about the future of the planet—from where umbrellas may be most needed in a given season to where electricity needs might sap the grid.

Today, computers are much more powerful than when Lorenz was working, and scientists use a special kind of simulation that accounts for physics, chemistry, biology, and water cycles to try to grasp the past and predict the future. These simulations, called Earth system models, or ESMs, attempt to consider the planet as a system made up of components that nudge and shove each other. Scientists first developed physical climate models in the 1960s and 1970s, and became better at integrating atmospheric and ocean models in subsequent years. As both environmental knowledge and computing power increased, they began to sprinkle in the other variables, leading to current-day ESMs.

“It’s coupling together usually an atmosphere model, an ocean model, a sea ice model, land model, together to get a full picture of a physical system,” said David Lawrence, a senior scientist at the National Center for Atmospheric Research’s Climate and Global Dynamics Laboratory, which he noted was recently changed to the CGD Laboratory to remove the word climate. The models also move beyond the planet’s physical components, including chemistry and biology.

In doing so, ESMs can find surprising conclusions. In 2023, for instance, the Energy Exascale Earth System Model, or E3SM, which was built by the Department of Energy, found that in the simulation, the shapes of cavities in Antarctic ice significantly affect tides many miles away, along the North American coast. That hemisphere-separated connection is just one example of how including an unexpected variable can affect a real-world outcome, and just one of many examples to emerge from E3SM.

E3SM is one of the world’s premier Earth system models, one DOE has worked on for more than a decade, led by Lawrence Livermore National Laboratory in California. But as part of budget and programmatic cuts being proposed under the administration of President Donald Trump, E3SM and Earth system research are under threat: The model’s website has been scrubbed of some information, and proposed federal budgets have terminated its future use for climate-related activities—one of its core functions—though it’s unclear how exactly that will play out. Outside researchers could, of course, use the model to study any research questions they desire, provided they could get funding.

E3SM is much finer-grained than most such models, providing more tailored and accurate results over a given region. It’s used to predict extreme events, like floods, and unlike most other models, to understand how the climate interacts with the power system—like how that extreme weather may tax the grid or cause it to falter. Both kinds of studies matter to humans living their lives, in addition to weather wonks.

DOE has already announced about $100 million in funding between 2018 and 2022, according to publicly available statements Undark located, to enhance and improve the model. That sum doesn’t include the resources that would have gone into its initial development. Those more recent investments may now be in question. “There’s nothing definitive,” said Lawrence. But the agency’s proposed budget would decrease both funding and capability.

Meanwhile, experts say that funding cuts could mean modeling abilities migrate overseas, some science may never be realized, and expertise could be lost.

With that toss-off of talent, said Andrew Dessler, a professor of atmospheric sciences at Texas A&M University, countries like China may catch up to the US “It would have been very hard for them to have a more respected scientific organization or scientific system than the US did,” Dessler said. “Our research universities are really the envy of the world, and our government labs are the envy of the world.”

But they won’t be, he said, if the country loses the expertise of those who work in them.

E3SM scientists want to understand how Earth changes over time and how much conditions vary within long-term projections—like, say, how average temperature may creep up over time, but extremely low temperatures blast Colorado nevertheless. Eventually, these scientists hope to incorporate enough chemistry, physics, and biology to create a “digital twin” of the planet—modeling Earth in a way true to its real form.

That’s a lofty goal, especially since reaching even the current, less twin-like stage took scientists more than 10 years of software development and tweaking. “The models are very big in terms of how much code there is,” said Lawrence, the earth system scientist at NCAR. (Through a spokesperson, Lawrence Livermore National Laboratory, whose scientists lead the model’s development, declined to comment for this story. “We aren’t able to offer interviews about E3SM at this time,” lab spokesperson Jeremy Thomas wrote in an email; he did not respond to an emailed question about why.)

Lawrence, though, knows this, as head of a similar project, called the Community Earth System Model, an early version of which served as a basis for E3SM.

Around 30 years ago, scientists at NCAR began working on the community model building on an existing foundation at the agency. In building the community model, they collaborated with DOE researchers, and the agency co-sponsored the model. Later, though, DOE decided to pursue slightly different research priorities, according to Lawrence.

One of those priorities, which they started pursuing in 2014 with the official launch of the project, involved taking advantage of powerful computers. The agency, in addition to studying climate and energy, is also in charge of nuclear weapons. It possesses some of the world’s most powerful supercomputers to simulate those weapons’ inner workings and do science on the side.

DOE, true to its name, also wanted to focus on energy issues. Understanding the planet’s weather and water machinations is critical for, say, knowing how to cool power stations, or when temperatures might tax the grid. NCAR scientists were less focused on energy and didn’t have the same computational bite, according to Lawrence.

And so the two groups split. After around a decade of development, E3SM scientists achieved their main goal in 2023: a terrestrial simulation built for an exascale supercomputer (“exascale” means the supercomputer can do a quintillion calculations per second—millions of times faster than a laptop). After a review planned for later this year, the project is slated to begin its fourth iteration in 2026.

E3SM has been useful to DOE researchers but also to independent ones, who use the model to answer their own burning questions. Environmental researcher Yi Yao, for instance, used E3SM to understand how irrigation affects not just the planet but the people on it. “It’s very important to know that the human activities are altering the system, and it may cause some catastrophic consequences,” said Yao, a postdoc at ETH Zurich who, along with co-authors, published his study’s findings in Nature Communications.

Irrigation, he found, contributes to “moist heat”—essentially, humidity, natural and human-caused. “Farmers who were working in the field, their health—their life even—can be endangered by the moist heat,” he said, not something their employers generally forecast for when irrigating and planning operations. Irrigation, in fact, has been proposed as a strategy for managing heat, by cooling surface temperature, something his study shows wouldn’t be effective.

Importantly, Yao’s work compared results from a variety of ESMs. That’s common practice in the field, and part of why having multiple models is important. “Obviously the physics of the world, the biology of the world, the chemistry of the world, there’s just one version of it,” explained Lawrence. “But how you represent that is so complex that there is no one answer.” Interpolating between different answers helps scientists learn more than they might from a single model alone.

Other scientists have recently used E3SM to find that rising average temperatures can turn farmlands into carbon creators instead of carbon sinks, that intense rains push nutrients into the Gulf of Mexico, and that Pacific hurricanes that first speed west but then turn tail northward decrease the number of forest fires in the American southwest.

But beyond big climatic questions, Earth system models like E3SM are also useful on a more practical level. That’s especially true as scientists work to make them more reliable over time, “so you can really use them for making all sorts of decisions, whether it’s what you’re going to do for your summer vacation to how are you going to deal with sea-level rise in your region,” said Lawrence. How useful and available American ESMs will be in the coming years, though, is a question of money and its disappearance. Overall, climate research at DOE has been in the crosshairs of the Trump administration. In the skinny budget request for the department’s Office of Science, the administration noted that “the Budget reduces funding for climate change and Green New Scam research,” referencing the proposed Green New Deal, with a cut of more than $1 billion to the DOE’s Office of Science.

According to the DOE’s recent budget request, though, E3SM will continue to exist, but seemingly without one of its primary raisons d’etre. “Any Energy Exascale Earth System Model (E3SM) activities involving climate are terminated,” reads the 2025 budget request, although it is unclear how a climate model can skirt around the climate.

“I do not know to what extent we can say that a topic has nothing to do with climate,” said Yao in an email. “Considering that atmosphere is one important component of the Earth System, it would be very difficult to fully exclude climate.” He did note, though, that some studies are not dedicated to the impacts of climate change but, say, to ecological applications or hydrology. “I do not think it is appropriate to call them having nothing to do with climate but in these cases, they are not used for climate predictions,” he wrote.

The document earmarks “investments on further refinement of the science serving administration priorities,” and details technology that will be used to advance the model, like AI and more powerful computers. It doesn’t specify what goals that AI might serve, beyond enabling higher resolution.

In 2026, the proposed budget decreases DOE funding for Earth and environmental system modeling from around $110 million to $30 million. “Funding will be consolidated under this subprogram to focus on supporting the administration’s highest priority research,” the document notes. It does not specify what those priorities are.

Meanwhile, the National Science Foundation’s budget request notes that its funding of NCAR, which oversees the lab Lawrence works for, will “curtail but continue to support research to refine weather and Earth system models and to better understand the evolution of wildland fires.” The federal government terminated a grant supporting an update to the model, although much of the work was already completed.

And the National Oceanic and Atmospheric Administration proposed a funding decrease of around 25 percent, with many of the cuts related to climate change. For many experts in the field, the future of this research can feel unpredictable, like the weather itself.

These cuts have scientists worried globally. In Europe, where Yao is based, what will become of the American ESMs is of great concern. “This is the topic of every lunch table here,” he said.

“It’s quite sad,” he added, “because the USA has always been a leader in the field.”

But it’s hard for US scientists to lead if they can’t describe their work, as some government guidance now forbids certain key terms. Indeed, according to a May report from a local newspaper, an internal publication from Lawrence Livermore noted that the laboratory “has been directed to reword or remove specific words and phrases from all external-facing media, web pages and public-facing communications.” Those terms included “climate change.” When asked by email about the report, Jeremy Thomas, a public information officer for Lawrence Livermore wrote, “We can’t comment on The Independent’s reporting.”

In the view of Dessler, the Texas-based professor, these cuts aren’t just climate-change denial on a scientific basis. “There’s a push to get rid of science that can be used to regulate,” he said—whether that has to do with pesticides or carbon.

But even if the models are curtailed in the US, options may exist to keep them sailing—by, for instance, duplicating their capabilities elsewhere. That has happened on the data side before: In the previous Trump administration, people feared the government would delete climate data, so people like John Baez, an emeritus mathematician at the University of California, Riverside who is now working at the University of Edinburgh, backed it up. In the current administration, others have leaped into action, creating archives like the Safeguarding Research & Culture project, which has collected a variety of datasets and publications—from satellite observations of coral reefs to space telescope observations of distant planets—and made sure they’re public and available.

Scientists could theoretically do something similar for ESMs. “You can reestablish that model,” Baez said. “So if some European government decides to take on responsibility for this exascale model, I can imagine that being done.” However, noted Lawrence, to be useful, a model needs to be accompanied by staff with the relevant scientific and technical expertise to run it.

To think that other countries could gather all those ingredients at once might be optimistic. “It’s not like this is the only responsibility that’s something being dropped in the lap of other countries,” said Baez, “and whether they will have the funds and the energy to pursue all of these, it’s actually unlikely.”

Dessler said that if E3SM disappears, or isn’t supported, people could use CESM, which has the same technological origins. Beyond that, said Dessler, other ESMs exist. And they’re still plenty advanced even if they’re not exascale.

To Dessler, the potential obsolescence of any given model is not the issue. “I think the much bigger problem is they’re just going to zero out the work being done at DOE on climate,” he said.

And that zeroing includes people. “What’s really chilling, I think, is the loss of human capital,” he said.

“You cannot generate a scientist out of thin air,” he continued. “It takes years to produce a scientist, and to produce a senior scientist takes decades. And so if you don’t have any senior scientists, you’re screwed for a very long time.”

To understand how that changing variable will affect the planet would likely require a model even more powerful than an ESM.

“I think that’s really the story,” Dessler said.
