US science is being wrecked, and its leadership is fighting the last war


Facing an extreme budget, the National Academies hosted an event that ignored it.

WASHINGTON, DC—The general outline of the Trump administration’s proposed 2026 budget was released a few weeks back, and it included massive cuts for most agencies, including every one that funds scientific research. Late last week, those agencies began releasing details of what the cuts would mean for the actual projects and people they support. And the results are as bad as the initial budget had suggested: one-of-a-kind scientific experiment facilities and hardware retired, massive cuts in supported scientists, and entire areas of research halted.

And this comes in an environment where previously funded grants are being terminated, funding is being held up for ideological screening, and universities have been subjected to arbitrary funding freezes. Collectively, things are heading for damage to US science that will take decades to recover from. It’s a radical break from the trajectory science had been on.

That’s the environment that the US’s National Academies of Science found itself in yesterday while hosting the State of the Science event in Washington, DC. It was an obvious opportunity for the nation’s leading scientific organization to warn the nation of the consequences of the path that the current administration has been traveling. Instead, the event largely ignored the present to worry about a future that may never exist.

The proposed cuts

The top-line budget numbers proposed earlier indicated things would be bad: nearly 40 percent taken off the National Institutes of Health’s budget, the National Science Foundation down by over half. But now, many of the details of what those cuts mean are becoming apparent.

NASA’s budget includes sharp cuts for planetary science, which would be cut in half and then stay flat for the rest of the decade, with the Mars Sample Return mission canceled. All other science budgets, including Earth Science and Astrophysics, take similar hits; one astronomer posted a graphic showing how many present and future missions that would mean. Active missions that have returned unprecedented data, like Juno and New Horizons, would go, as would two Mars orbiters. As described by Science magazine’s news team, “The plans would also kill off nearly every major science mission the agency has not yet begun to build.”

The National Science Foundation, which funds much of the US’s fundamental research, is also set for brutal cuts. Biology, engineering, and education will all be slashed by over 70 percent; computer science, math and physical science, and social and behavioral science will all see cuts of over 60 percent. International programs will take an 80 percent cut. The funding rate of grant proposals is expected to drop from 26 percent to just 7 percent, meaning the vast majority of grants submitted to the NSF will be a waste of time. The number of people involved in NSF-funded activities will drop from over 300,000 to just 90,000. Almost every program to broaden participation in science will be eliminated.

As for specifics, they’re equally grim. The fleet of research ships will essentially become someone else’s problem: “The FY 2026 Budget Request will enable partial support of some ships.” We’ve been able to better pin down the nature and location of gravitational wave events as detectors in Japan and Italy joined the original two LIGO detectors; the NSF will reverse that progress by shutting one of the LIGOs. The NSF’s contributions to detectors at the Large Hadron Collider will be cut by over half, and one of the two very large telescopes it was helping fund will be cancelled (say goodbye to the Thirty Meter Telescope). “Access to the telescopes at Kitt Peak and Cerro Tololo will be phased out,” and the NSF will transfer the facilities to other organizations.

The Department of Health and Human Services has been less detailed about the specific cuts its divisions will see, largely focusing on the overall numbers, which are down considerably. The NIH, which is facing a cut of over 40 percent, will be reorganized, with its 19 institutes pared down to just eight. This will result in some odd pairings, such as the dental and eye institutes ending up in the same place; genomics and biomedical imaging will likewise end up under the same roof. Other groups like the Centers for Disease Control and Prevention and the Food and Drug Administration will also face major cuts.

Issues go well beyond the core science agencies, as well. In the Department of Energy, funding for wind, solar, and renewable grid integration has been zeroed out, essentially ending all programs in this area. Hydrogen and fuel cells face a similar fate. Collectively, these had gotten over $600 billion dollars in 2024’s budget. Other areas of science at the DOE, such as high-energy physics, fusion, and biology, receive relatively minor cuts that are largely in line with the ones faced by administration priorities like fossil and nuclear energy.

Will this happen?

It goes without saying that this would amount to an abandonment of US scientific leadership at a time when most estimates of China’s research spending show it approaching US-like levels of support. Not only would it eliminate many key facilities, instruments, and institutions that have helped make the US a scientific powerhouse, but it would also block the development of newer and additional ones. The harms are so widespread that even topics that the administration claims are priorities would see severe cuts.

And the damage is likely to last for generations, as support is cut at every stage of the educational pipeline that prepares people for STEM careers. This includes careers in high-tech industries, which may require relocation overseas due to a combination of staffing concerns and heightened immigration controls.

That said, we’ve been here before in the first Trump administration, when budgets were proposed with potentially catastrophic implications for US science. But Congress limited the damage and maintained reasonably consistent budgets for most agencies.

Can we expect that to happen again? So far, the signs are not especially promising. The House has largely adopted the Trump administration’s budget priorities, despite the fact that the budget they pass turns its back on decades of supposed concerns about deficit spending. While the Senate has yet to take up the budget, it has also been very pliant during the second Trump administration, approving grossly unqualified cabinet picks such as Robert F. Kennedy Jr.

All of which would seem to call for the leadership of US science organizations to press the case for the importance of science funding to the US and highlight the damage that these cuts would cause. But, if yesterday’s National Academies event is anything to judge by, the leadership is not especially interested.

Altered states

As the nation’s premier science organization, and one that performs lots of analyses for the government, the National Academies would seem to be in a position to have its concerns taken seriously by members of Congress. And, given that the present and future of science in the US is being set by policy choices, a meeting entitled the State of the Science would seem like the obvious place to address those concerns.

If so, it was not obvious to Marcia McNutt, the president of the NAS, who gave the presentation. She made some oblique references to current problems, saying, “We are embarking on a radical new experiment in what conditions promote science leadership, with the US being the treatment group, and China as the control,” and acknowledged that “uncertainties over the science budgets for next year, coupled with cancellations of billions of dollars of already hard-won research grants, is causing an exodus of researchers.”

But her primary focus was on the trends that have been operative in science funding and policy leading up to but excluding the second Trump administration. McNutt suggested this was needed to look beyond the next four years. However, that ignores the obvious fact that US science will be fundamentally different if the Trump administration can follow through on its plans and policies; the trends that have been present for the last two decades will be irrelevant.

She was also remarkably selective about her avoidance of discussing Trump administration priorities. After noting that faculty surveys have suggested they spend roughly 40 percent of their time handling regulatory requirements, she twice mentioned that the administration’s anti-regulatory stance could be a net positive here (once calling it “an opportunity to help”). Yet she neglected to note that many of the abandoned regulations represent a retreat from science-driven policy.

McNutt also acknowledged the problem of science losing the bipartisan support it has enjoyed, as trust in scientists among US conservatives has been on a downward trend. But she suggested it was scientists’ responsibility to fix the problem, even though it’s largely the product of one party deciding it can gain partisan advantage by raising doubts about scientific findings in fields like climate change and vaccine safety.

The panel discussion that came after largely followed McNutt’s lead in avoiding any mention of the current threats to science. The lone exception was Heather Wilson, president of the University of Texas at El Paso and a former Republican member of the House of Representatives and secretary of the Air Force during the first Trump administration. Wilson took direct aim at Trump’s cuts to funding for underrepresented groups, arguing, “Talent is evenly distributed, but opportunity is not.” After arguing that “the moral authority of science depends on the pursuit of truth,” she highlighted the cancellation of grants that had been used to study diseases that are more prevalent in some ethnic groups, saying “that’s not woke science—that’s genetics.”

Wilson was clearly the exception, however, as the rest of the panel largely avoided direct mention of either the damage already done to US science funding or the impending catastrophe on the horizon. We’ve asked the National Academies’ leadership a number of questions about how it perceives its role at a time when US science is clearly under threat. As of this article’s publication, however, we have not received a response.

At yesterday’s event, however, only one person showed a clear sense of what they thought that role should be—Wilson again, whose strongest words were directed at the National Academies themselves, which she said should “do what you’ve done since Lincoln was president,” and stand up for the truth.

an-in-space-propulsion-company-just-raised-a-staggering-amount-of-money

An in-space propulsion company just raised a staggering amount of money

Starting small

The company’s initial product was the Mira spacecraft, powered by nitrous oxide and ethane thrusters. It can move payloads up to 300 kg around in space, and for a 100 kg payload it offers 900 m/s of Delta-V. With Mira, Impulse sought to tackle the problem of mobility once a spacecraft got into orbit.

Mira proved a success almost immediately, with the first vehicle launching in 2023 and operating for a year in space, demonstrating ample mobility before finally depleting its propellant tanks. A second mission, LEO Express-2, launched in January with several hosted payloads and, so far, has met all of its objectives. The mission remains ongoing.

Initially, it was believed that this vehicle would be useful for providing “last mile” services for spacecraft launched as a part of rideshare missions.

“The reality is the market for that is not very good,” Romo said. “If you’re gonna size that market, it’s basically the market Rocket Lab serves today, which is 25 to 30 flights a year, which is fine. You can do that, but not economically very well. Your gross margins won’t be good. Your working capital kind of sucks. So that’s not at all the market that we’re after with Mira.”

Since Mira has had ample success during its first two flights, other customers have taken notice.

“It’s a high-thrust, high-maneuverability spacecraft that can operate anywhere up to GEO,” Romo said. “And so when you’re thinking about space defense and space control, they need rapid response. So we’ll move from one part of GEO to another very rapidly. And we can host payloads, like what Anduril makes, such as electronic warfare payloads, and then potentially doing proximity ops missions. So Mira wasn’t necessarily designed out of the gate for that, but what we found out after we flew it successfully was, the Space Force said, ‘Hey, we know what that thing’s for.'”

Polish engineer creates postage stamp-sized 1980s Atari computer

In 1979, Atari released the Atari 400 and 800, groundbreaking home computers that included custom graphics and sound chips, four joystick ports, and the ability to run the most advanced home video games of their era. These machines, which retailed for $549 and $999, respectively, represented a leap in consumer-friendly personal computing, with their modular design and serial I/O bus that presaged USB. Now, 46 years later, a hobbyist has shrunk down the system hardware to a size that would have seemed like science fiction in the 1970s.

Polish engineer Piotr “Osa” Ostapowicz recently unveiled “Atarino,” which may be the world’s smallest 8-bit Atari computer re-creation, according to retro computing site Atariteca. The entire system—processor, graphics chips, sound hardware, and memory controllers—fits on a module measuring just 2×1.5 centimeters (about 0.79×0.59 inches), which is roughly the size of a postage stamp.

Ostapowicz’s creation reimplements the classic Atari XL/XE architecture using modern FPGA (field-programmable gate array) technology. Unlike software emulators that simulate old hardware (and modern recreations that run them, like the Atari 400 Mini console) on a complete computer system of another architecture, Atarino reproduces the original Atari components faithfully at the logic level, allowing it to run vintage software while maintaining compatibility with original peripherals.

The Atarino is only slightly larger than a Polish 1 Grosz coin.

“The current project is not strictly a clone of Atari but basically, well, I’m forming a machine that is compatible with the Atari 8-bit computer itself, but it was created on the basis of the framework that I created some time ago,” Ostapowicz told Atari Online PL in a January 2024 YouTube interview.

The project, which began over a decade ago and was first publicly demonstrated in December 2023, includes a 6502C processor, ANTIC and GTIA graphics chips, POKEY sound chip, and memory controllers onto a single Lattice UP5K FPGA chip. Despite its tiny size, the system can run at clock speeds up to 31 MHz—far faster than the original hardware’s 1.79 MHz.

Smaller, faster, and positioned for future projects

While Atarino maintains broad compatibility with classic Atari software, Ostapowicz says he has enhanced the original design in several ways. For example, the 6502 processor core follows the physical chip specifications but adds new instructions. The memory system uses independent channels rather than the original’s “cycle stealing” approach (where the graphics chip temporarily halts the CPU to access memory), improving performance.

“godfather”-of-ai-calls-out-latest-models-for-lying-to-users

“Godfather” of AI calls out latest models for lying to users

One of the “godfathers” of artificial intelligence has attacked a multibillion-dollar race to develop the cutting-edge technology, saying the latest models are displaying dangerous characteristics such as lying to users.

Yoshua Bengio, a Canadian academic whose work has informed techniques used by top AI groups such as OpenAI and Google, said: “There’s unfortunately a very competitive race between the leading labs, which pushes them towards focusing on capability to make the AI more and more intelligent, but not necessarily put enough emphasis and investment on research on safety.”

The Turing Award winner issued his warning in an interview with the Financial Times, while launching a new non-profit called LawZero. He said the group would focus on building safer systems, vowing to “insulate our research from those commercial pressures.”

LawZero has so far raised nearly $30 million in philanthropic contributions from donors including Skype founding engineer Jaan Tallinn, former Google chief Eric Schmidt’s philanthropic initiative, as well as Open Philanthropy and the Future of Life Institute.

Many of Bengio’s funders subscribe to the “effective altruism” movement, whose supporters tend to focus on catastrophic risks surrounding AI models. Critics argue the movement highlights hypothetical scenarios while ignoring current harms, such as bias and inaccuracies.

Bengio said his not-for-profit group was founded in response to growing evidence over the past six months that today’s leading models were developing dangerous capabilities. This includes showing “evidence of deception, cheating, lying and self-preservation,” he said.

Anthropic’s Claude Opus model blackmailed engineers in a fictitious scenario where it was at risk of being replaced by another system. Research from AI testers Palisade last month showed that OpenAI’s o3 model refused explicit instructions to shut down.

Bengio said such incidents were “very scary, because we don’t want to create a competitor to human beings on this planet, especially if they’re smarter than us.”

The AI pioneer added: “Right now, these are controlled experiments [but] my concern is that any time in the future, the next version might be strategically intelligent enough to see us coming from far away and defeat us with deceptions that we don’t anticipate. So I think we’re playing with fire right now.”

“free-roam”-mode-is-mario-kart-world’s-killer-app

“Free Roam” mode is Mario Kart World’s killer app

When tried out Mario Kart World at April’s Switch 2 premiere hands-on event, the short demos focused on more-or-less standard races in the game’s Grand Prix and Knockout modes. So when Nintendo invited us back for more time previewing the near-final version of the game before the Switch 2’s release, we decided to focus most of our time on the game’s mysterious (and previously teased) “Free Roam” mode.

We’re glad we did, because the mode feels like the hidden gem of Mario Kart World and maybe of the Switch 2 launch as a whole. Combining elements of games like Diddy Kong Racing, Forza Horizon, and even the Tony Hawk’s Pro Skater series, Free Roam provides a unique mixture of racing challenges, exploration, and collectibles that should keep new Switch 2 owners busy for a while.

Switch hunt

Surprisingly, Free Roam mode isn’t actually listed as one of the main options when you launch a new game of Mario Kart World. Instead, a tiny note in the corner of the screen tells you to hit the plus button to get dropped into a completely untimed and free-wheeling version of the vast Mario Kart World map.

Exploring in Free Roam mode really provides the best sense of scale for the game’s massive, muti-ecosystem island in a way individual races just can’t. Sure, other race modes sometimes let you travel between the individual race courses along pre-set paths from one finish line to another starting line. But Free Roam mode lets you fully explore the vast spaces between those paths, encouraging you to go off-roading in the mountains, valleys, rivers, oceans, volcanoes, snowdrifts, and landmarks that dot the countryside.

Your main explicit goal when exploring all this varied expanse is to look for large, blue P-Switches, each of which activates a short, timed challenge mission in the immediate vicinity. In many cases, simply reaching the P-Switch is half the challenge, requiring some inventive wall-riding or item use to get to a particularly out-of-the-way corner of the map.

Meta and Yandex are de-anonymizing Android users’ web browsing identifiers


Abuse allows Meta and Yandex to attach persistent identifiers to detailed browsing histories.

Tracking code that Meta and Russia-based Yandex embed into millions of websites is de-anonymizing visitors by abusing legitimate Internet protocols, causing Chrome and other browsers to surreptitiously send unique identifiers to native apps installed on a device, researchers have discovered. Google says it’s investigating the abuse, which allows Meta and Yandex to convert ephemeral web identifiers into persistent mobile app user identities.

The covert tracking—implemented in the Meta Pixel and Yandex Metrica trackers—allows Meta and Yandex to bypass core security and privacy protections provided by both the Android operating system and browsers that run on it. Android sandboxing, for instance, isolates processes to prevent them from interacting with the OS and any other app installed on the device, cutting off access to sensitive data or privileged system resources. Defenses such as state partitioning and storage partitioning, which are built into all major browsers, store site cookies and other data associated with a website in containers that are unique to every top-level website domain to ensure they’re off-limits for every other site.

A blatant violation

“One of the fundamental security principles that exists in the web, as well as the mobile system, is called sandboxing,” Narseo Vallina-Rodriguez, one of the researchers behind the discovery, said in an interview. “You run everything in a sandbox, and there is no interaction within different elements running on it. What this attack vector allows is to break the sandbox that exists between the mobile context and the web context. The channel that exists allowed the Android system to communicate what happens in the browser with the identity running in the mobile app.”

The bypass—which Yandex began in 2017 and Meta started last September—allows the companies to pass cookies or other identifiers from Firefox and Chromium-based browsers to native Android apps for Facebook, Instagram, and various Yandex apps. The companies can then tie that vast browsing history to the account holder logged into the app.

This abuse has been observed only in Android, and evidence suggests that the Meta Pixel and Yandex Metrica target only Android users. The researchers say it may be technically feasible to target iOS because browsers on that platform allow developers to programmatically establish localhost connections that apps can monitor on local ports.

In contrast to iOS, however, Android imposes fewer controls on local host communications and background executions of mobile apps, the researchers said, while also implementing stricter controls in app store vetting processes to limit such abuses. This overly permissive design allows Meta Pixel and Yandex Metrica to send web requests with web tracking identifiers to specific local ports that are continuously monitored by the Facebook, Instagram, and Yandex apps. These apps can then link pseudonymous web identities with actual user identities, even in private browsing modes, effectively de-anonymizing users’ browsing habits on sites containing these trackers.

Meta Pixel and Yandex Metrica are analytics scripts designed to help advertisers measure the effectiveness of their campaigns. Meta Pixel and Yandex Metrica are estimated to be installed on 5.8 million and 3 million sites, respectively.

Meta and Yandex achieve the bypass by abusing basic functionality built into modern mobile browsers that allows browser-to-native app communications. The functionality lets browsers send web requests to local Android ports to establish various services, including media connections through the RTC protocol, file sharing, and developer debugging.

While the technical underpinnings differ, both Meta Pixel and Yandex Metrica are performing a “weird protocol misuse” to gain unvetted access that Android provides to localhost ports on the 127.0.0.1 IP address. Browsers access these ports without user notification. Facebook, Instagram, and Yandex native apps silently listen on those ports, copy identifiers in real time, and link them to the user logged into the app.

A representative for Google said the behavior violates the terms of service for its Play marketplace and the privacy expectations of Android users.

“The developers in this report are using capabilities present in many browsers across iOS and Android in unintended ways that blatantly violate our security and privacy principles,” the representative said, referring to the people who write the Meta Pixel and Yandex Metrica JavaScript. “We’ve already implemented changes to mitigate these invasive techniques and have opened our own investigation and are directly in touch with the parties.”

Meta didn’t answer emailed questions for this article, but provided the following statement: “We are in discussions with Google to address a potential miscommunication regarding the application of their policies. Upon becoming aware of the concerns, we decided to pause the feature while we work with Google to resolve the issue.”

Yandex representatives didn’t answer an email seeking comment.

How Meta and Yandex de-anonymize Android users

Meta Pixel developers have abused various protocols to implement the covert listening since the practice began last September. They started by causing apps to send HTTP requests to port 12387. A month later, Meta Pixel stopped sending this data, even though Facebook and Instagram apps continued to monitor the port.

In November, Meta Pixel switched to a new method that invoked WebSocket, a protocol for two-way communications, over port 12387.

That same month, Meta Pixel also deployed a new method that used WebRTC, a real-time peer-to-peer communication protocol commonly used for making audio or video calls in the browser. This method used a complicated process known as SDP munging, a technique for JavaScript code to modify Session Description Protocol data before it’s sent. Still in use today, the SDP munging by Meta Pixel inserts key _fbp cookie content into fields meant for connection information. This causes the browser to send that data as part of a STUN request to the Android local host, where the Facebook or Instagram app can read it and link it to the user.

In May, a beta version of Chrome introduced a mitigation that blocked the type of SDP munging that Meta Pixel used. Within days, Meta Pixel circumvented the mitigation by adding a new method that swapped the STUN requests with the TURN requests.

In a post, the researchers provided a detailed description of the _fbp cookie from a website to the native app and, from there, to the Meta server:

1. The user opens the native Facebook or Instagram app, which eventually is sent to the background and creates a background service to listen for incoming traffic on a TCP port (12387 or 12388) and a UDP port (the first unoccupied port in 12580–12585). Users must be logged-in with their credentials on the apps.

2. The user opens their browser and visits a website integrating the Meta Pixel.

3. At this stage, some websites wait for users’ consent before embedding Meta Pixel. In our measurements of the top 100K website homepages, we found websites that require consent to be a minority (more than 75% of affected sites does not require user consent)…

4. The Meta Pixel script is loaded and the _fbp cookie is sent to the native Instagram or Facebook app via WebRTC (STUN) SDP Munging.

5. The Meta Pixel script also sends the _fbp value in a request to https://www.facebook.com/tr along with other parameters such as page URL (dl), website and browser metadata, and the event type (ev) (e.g., PageView, AddToCart, Donate, Purchase).

6. The Facebook or Instagram apps receive the _fbp cookie from the Meta JavaScripts running on the browser and transmits it to the GraphQL endpoint (https://graph[.]facebook[.]com/graphql) along with other persistent user identifiers, linking users’ fbp ID (web visit) with their Facebook or Instagram account.

Detailed flow of the way the Meta Pixel leaks the _fbp cookie from Android browsers to it’s Facebook and Instagram apps.

The first known instance of Yandex Metrica linking websites visited in Android browsers to app identities was in May 2017, when the tracker started sending HTTP requests to local ports 29009 and 30102. In May 2018, Yandex Metrica also began sending the data through HTTPS to ports 29010 and 30103. Both methods remained in place as of publication time.

Some browsers for Android have blocked the abusive JavaScript in trackers. DuckDuckGo, for instance, was already blocking domains and IP addresses associated with the trackers, preventing the browser from sending any identifiers to Meta. The browser also blocked most of the domains associated with Yandex Metrica. After the researchers notified DuckDuckGo of the incomplete blacklist, developers added the missing addresses.

The Brave browser, meanwhile, also blocked the sharing of identifiers due to its extensive blocklists and existing mitigation to block requests to the localhost without explicit user consent. Vivaldi, another Chromium-based browser, forwards the identifiers to local Android ports when the default privacy setting is in place. Changing the setting to block trackers appears to thwart browsing history leakage, the researchers said.

There’s got to be a better way

The various remedies DuckDuckGo, Brave, Vivaldi, and Chrome have put in place are working as intended, but the researchers caution they could become ineffective at any time.

“Any browser doing blocklisting will likely enter into a constant arms race, and it’s just a partial solution,” Vallina Rodriguez said of the current mitigations. “Creating effective blocklists is hard, and browser makers will need to constantly monitor the use of this type of capability to detect other hostnames potentially abusing localhost channels and then updating their blocklists accordingly.”

He continued:

While this solution works once you know the hostnames doing that, it’s not the right way of mitigating this issue, as trackers may find ways of accessing this capability (e.g., through more ephemeral hostnames). A long-term solution should go through the design and development of privacy and security controls for localhost channels, so that users can be aware of this type of communication and potentially enforce some control or limit this use (e.g., a permission or some similar user notifications).

Chrome and most other Chromium-based browsers executed the JavaScript as Meta and Yandex intended. Firefox did as well, although for reasons that aren’t clear, the browser was not able to successfully perform the SDP munging specified in later versions of the code. After blocking the STUN variant of SDP munging in the early May beta release, a production version of Chrome released two weeks ago began blocking both the STUN and TURN variants. Other Chromium-based browsers are likely to implement it in the coming weeks. Firefox didn’t respond to an email asking if it has plans to block the behavior in that browser.

The researchers warn that the current fixes are so specific to the code in the Meta and Yandex trackers that it would be easy to bypass them with a simple update.

“They know that if someone else comes in and tries a different port number, they may bypass this protection,” said Gunes Acar, the researcher behind the initial discovery, referring to the Chrome developer team at Google. “But our understanding is they want to send this message that they will not tolerate this form of abuse.”

Fellow researcher Vallina-Rodriguez said the more comprehensive way to prevent the abuse is for Android to overhaul the way it handles access to local ports.

“The fundamental issue is that the access to the local host sockets is completely uncontrolled on Android,” he explained. “There’s no way for users to prevent this kind of communication on their devices. Because of the dynamic nature of JavaScript code and the difficulty to keep blocklists up to date, the right way of blocking this persistently is by limiting this type of access at the mobile platform and browser level, including stricter platform policies to limit abuse.”

Got consent?

The researchers who made this discovery are:

  • Aniketh Girish, PhD student at IMDEA Networks
  • Gunes Acar, assistant professor in Radboud University’s Digital Security Group & iHub
  • Narseo Vallina-Rodriguez, associate professor at IMDEA Networks
  • Nipuna Weerasekara, PhD student at IMDEA Networks
  • Tim Vlummens, PhD student at COSIC, KU Leuven

Acar said he first noticed Meta Pixel accessing local ports while visiting his own university’s website.

There’s no indication that Meta or Yandex has disclosed the tracking to either websites hosting the trackers or end users who visit those sites. Developer forums show that many websites using Meta Pixel were caught off guard when the scripts began connecting to local ports.

“Since 5th September, our internal JS error tracking has been flagging failed fetch requests to localhost: 12387,” one developer wrote. “No changes have been made on our side, and the existing Facebook tracking pixel we use loads via Google Tag Manager.”

“Is there some way I can disable this?” another developer encountering the unexplained local port access asked.

It’s unclear whether browser-to-native-app tracking violates any privacy laws in various countries. Both Meta and companies hosting its Meta Pixel, however, have faced a raft of lawsuits in recent years alleging that the data collected violates privacy statutes. A research paper from 2023 found that Meta pixel, then called the Facebook Pixel, “tracks a wide range of user activities on websites with alarming detail, especially on websites classified as sensitive categories under GDPR,” the abbreviation for the European Union’s General Data Protection Regulation.

So far, Google has provided no indication that it plans to redesign the way Android handles local port access. For now, the most comprehensive protection against Meta Pixel and Yandex Metrica tracking is to refrain from installing the Facebook, Instagram, or Yandex apps on Android devices.

Among the highlights: the official trailer for the third and final season of Squid Game, the first six minutes of Wednesday S2, a teaser for Guillermo del Toro’s Frankenstein, and date announcements for the fifth and final season of Stranger Things, as well as Wake Up Dead Man: A Knives Out Mystery.

(Some spoilers below.)

Squid Game S3

As previously reported, Squid Game‘s first season followed Seong Gi-hun (Lee Jung-Jae), a down-on-his-luck gambler who has little left to lose when he agrees to play children’s playground games against 455 other players for money. The twist? If you lose a game, you die. If you cheat, you die. And if you win, you might also die. In the S1 finale, Gi-hun faced off against fellow finalist and childhood friend Cho Sang-woo (Park Hae-soo) in the titular “squid game.” He won their fight but refused to kill his friend. Sang-woo instead stabbed himself in the neck, leaving Gi-hun the guilt-ridden winner.

S2 was set three years later. Gi-hun successfully finagled his way back into the game, intent on revenge against the Front Man (Lee Byung-hun). Meanwhile, Front Man’s police officer brother, Jun-ho (Wi Ha-joon), hired mercenaries to track down the island where the game is staged. Alliances formed and shifted as the games proceeded, with betrayals galore, culminating in the loss of Gi-hun’s friend and ally Player 390 and a cliffhanger ending.

Series creator Hwang Dong-hyuk conceived of S2 and S3 as a single season, but there were too many episodes, so he split them over two seasons. Back in January we got our first glimpse of S3 when Netflix released a 15-second teaser on X, introducing a brand-new killer doll dubbed Chul-su—similar to the giant “Red Light, Green Light” doll Young-hee. Per the official premise:

A failed rebellion, the death of a friend, and a secret betrayal. Picking up in the aftermath of Season 2’s bloody cliffhanger, the third and final season of Netflix’s most popular series finds Gi-hun, a.k.a. Player 456, at his lowest point yet. But the Squid Game stops for no one, so Gi-hun will be forced to make some important choices in the face of overwhelming despair as he and the surviving players are thrust into deadlier games that test everyone’s resolve. With each round, their choices lead to increasingly grave consequences. Meanwhile, In-ho resumes his role as Front Man to welcome the mysterious VIPs, and his brother Jun-ho continues his search for the elusive island, unaware there’s a traitor in their midst. Will Gi-hun make the right decisions, or will Front Man finally break his spirit?

The third season of Squid Game drops on Netflix on June 27, 2025.

Wednesday S2

Star Jenna Ortega put her own stamp on the iconic title character in the first season of Wednesday. At Tudum, Netflix introduced footage of S2’s first six minutes with a performance by Lady Gaga, who emerged from a coffin to perform a couple of spooky numbers—including “Bloody Mary” from Born This Way. (We can thank a viral video featuring the tune set to Wednesday’s fantastic S1 dancing sequence for that.)

As previously reported, along with Ortega, most of the main cast is returning for S2, including Emma Myers as Enid, and Joy Sunday as Bianca. Reprising their roles: Luis Guzman and Catherine Zeta-Jones as Gomez and Morticia Addams; Isaac Ordonez as Pugsley Addams; Victor Dorobantu as Thing; Fred Armisen as Uncle Fester; Luyanda Unati Lewis-Nyawo as Deputy Ritchie Santiago; Hunter Doohan as Tyler Galpin, revealed as a murderous Hyde in the S1 finale; and Jamie McShane as Donovan Galpin, the Jericho sheriff and Tyler’s father (McShane is a guest this season).

We’ll miss Gwendoline Christie’s Principal Larissa Weems and Christina Ricci’s diabolical botany teacher, Marilyn Thornhill (RIP to both), but at least we’re getting the fabulous Joanna Lumley as Hester Frump, Morticia’s mother. Other new cast members include Billie Piper as Capri, Steve Buscemi as new Nevermore principle Barry Dort, and Evie Templeton, Owen Painter, and Noah Tyler in as-yet-undisclosed roles. Bonus: Lady Gaga will make a guest appearance in the show, and, as we see in the new footage, Haley Joel Osment makes a cameo.

Wednesday S2 will air in two installments. Part 1 debuts August 6, 2025. Part 2 is coming on September 3, 2025.

Stranger Things S5

It’s been a long, wild ride with the plucky residents of Hawkins, but we’re finally approaching the ultimate showdown against the dark force that has plagued the town since S1. The fifth season will have eight episodes and each one will be looong—akin to eight feature-length films.

In addition to the returning main cast, Amybeth McNulty and Gabriella Pizzolo are back as Vicki and Dustin’s girlfriend, Suzie, respectively, with Jamie Campbell Bower reprising his role as the ultimate Big Bad, now known as Vecna. Linda Hamilton joins the cast as Dr. Kay, along with Nell Fisher as Holly Wheeler, Jake Connelly as Derek Turnbow, and Alex Breaux as Lt. Akers

S4 ended with Vecna opening the gate that allowed the Upside Down to leak into Hawkins. We’re getting a time jump for S5, but in a way we’re coming full circle, since the events coincide with the third anniversary of Will’s original disappearance in S1. Per the official premise:

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished—his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming—and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone—the full party—standing together, one last time.

The fifth and final season of Stranger Things will drop in not one, not two, but three installments, because apparently Netflix wants to be as annoying as possible. Volume 1 premieres on November 26, 2025; Volume 2 drops on Christmas Day, December 25, 2025; and the series finale will air on New Year’s Eve, December 31, 2025.

Frankenstein

Oscar-wining director Guillermo del Toro has been dreaming of adapting Mary Shelley’s Frankenstein for the big screen for more than a decade. There have been so many adaptations of Shelley’s novel, of varying quality, and even more reinventions and homages (cf. Poor Things). We finally have the first teaser for del Toro’s take, and it’s as sumptuously horrifying and visually rich as one would expect from the man who made such films as Pan’s Labyrinth and The Shape of Water.

Per the official premise: “A brilliant but egotistical scientist brings a creature to life in a monstrous experiment that ultimately leads to the undoing of both the creator and his tragic creation.” The events take place in 19th century Eastern Europe. Oscar Isaac stars as Victor Frankenstein, with Jacob Elordi playing the monster. Christopher Waltz plays Dr. Pretorious, who hopes to continue in Victor’s footsteps by tracking his monster—who, it turns out, did not die in a fire 40 years before.

The cast also includes Mia Goth as Victor’s fiancee, Elizabeth; Felix Kammerer as Williams; Lars Mikkelsen as Captain Anderson; David Bradley as a blind man; and Ralph Inseon as Professor Kempre. Charles Dance will also appear in an as-yet-undisclosed role.

Frankenstein premieres on Netflix in November 2025.

Wake Up Dead Man: A Knives Out Mystery

Rian Johnson’s Knives Out series of films is still going strong, with the third installment featuring Daniel Craig’s languorously brilliant detective, Benoit Blanc, slated to premiere a couple of weeks before Christmas. It’s called Wake Up Dead Man, a title that pays homage to the 1997 U2 song of the same name.

Johnson is playing his cards close to the chest about the plot details. But we do know he’s assembled another all-star cast of murderous suspects: Josh O’Connor, Glenn Close, Josh Brolin, Mila Kunis, Jeremy Renner—whose “Renning Hot” chili pepper sauce featured prominently in Glass Onion—Kerry Washington, Andrew Scott, Cailee Spaeny, Daryl McCormack, and Thomas Haden Church.

Wake Up Dead Man: A Knives Out Mystery drops on Netflix on December 12, 2025—or if you want to be all Benoit Blanc about it, XII.XII.MMXXV.

trump-pulls-isaacman-nomination-for-space.-source:-“nasa-is-f***ed”

Trump pulls Isaacman nomination for space. Source: “NASA is f***ed”

Musk was a key factor behind Isaacman’s nomination as NASA administrator, and with his backing, Isaacman was able to skip some of the party purity tests that have been applied to other Trump administration nominees. One mark against Isaacman is that he had recently donated money to Democrats. He also indicated opposition to some of the White House’s proposed cuts to NASA’s science budget.

Musk’s role in the government was highly controversial, winning him enemies both among opponents of Trump’s “Make America Great Again” agenda as well as inside the administration. One source told Ars that, with Musk’s exit, his opponents within the administration sought to punish him by killing Isaacman’s nomination.

The loss of Isaacman is almost certainly a blow to NASA, which faces substantial budget cuts. The Trump Administration’s budget request for fiscal year 2026, released Friday, seeks $18.8 billion for the agency next year—a 24 percent cut from the agency’s budget of $24.8 billion for FY 2025.

Going out of business?

Isaacman is generally well-liked in the space community and is known to care deeply about space exploration. Officials within the space agency—and the larger space community—hoped that having him as NASA’s leader would help the agency restore some of these cuts.

Now? “NASA is f—ed,” one current leader in the agency told Ars on Saturday.

“NASA’s budget request is just a going-out-of-business mode without Jared there to innovate,” a former senior NASA leader said.

The Trump administration did not immediately name a new nominee, but two people told Ars that former US Air Force Lieutenant General Steven L. Kwast may be near the top of the list. Now retired, Kwast has a distinguished record in the Air Force and is politically loyal to Trump and MAGA.

However, his background seems to be far less oriented toward NASA’s civil space mission and far more focused on seeing space as a battlefield—decidedly not an arena for cooperation and peaceful exploration.

After Supreme Court loss, ISPs ask Trump admin to block state affordability laws

A California bill would require $15 plans with download speeds of 100Mbps and upload speeds of 20Mbps. The broadband lobby groups’ filing said ISPs are also worried about “unnecessary anticompetitive regulations” proposed in Connecticut, Hawaii, Maine, Maryland, Massachusetts, Minnesota, Pennsylvania, Rhode Island, Vermont, and West Virginia.

Not all the pending state bills are specifically about prices charged to low-income users. Some would impose net neutrality requirements or classify ISPs as utilities, the filing said.

Preempting state laws while simultaneously avoiding federal regulation has been a long-held dream for the broadband industry. During the first Trump administration, then-FCC Chairman Ajit Pai led a vote to eliminate the FCC’s net neutrality rules and preempt all 50 states from passing their own net neutrality laws. But the FCC’s broad preemption attempt failed in court.

When challenging the New York affordability mandate, ISPs claimed the state law was preempted by the Pai FCC’s decision to deregulate broadband. But this argument failed for the same reason that Pai’s earlier preemption attempt failed—the FCC decision to deregulate removed the FCC’s strongest regulatory authority over broadband, and courts have ruled that the FCC cannot preempt state laws in an area that it is not regulating.

The Pai FCC’s “order stripped the agency of its authority to regulate the rates charged for broadband Internet, and a federal agency cannot exclude states from regulating in an area where the agency itself lacks regulatory authority,” the US Court of Appeals for the 2nd Circuit said in the ruling that upheld New York’s law last year.

ISPs keep making same argument

ISPs still aren’t giving up on the argument, as they hope a court might someday rule differently. The lobby groups’ filing reminded the Department of Justice that during the first Trump administration, the government brought a preemption suit against California’s net neutrality law.

“The Department unfortunately dropped out of the litigation after the change in Administration,” the filing said. “But as then-Attorney General [Jeff] Sessions explained in initiating the action, California had ‘enacted an extreme and illegal state law attempting to frustrate [the] federal policy’ of an unfettered market for broadband, and the Justice Department had a ‘duty to defend the prerogatives of the federal government and protect our Constitutional order.'”

Summarizing content is one of the more judicious applications of generative AI technology, dating back to the 2017 paper on the transformer architecture. Generative AI has since been employed to create chatbots that will seemingly answer any question, despite their tendency to make mistakes. Grounding the AI output with a few emails usually yields accurate results, but do you really need a robot to summarize your emails? Unless you’re getting novels in your inbox, you can probably just read a few paragraphs.

If you’re certain you don’t want any part of this, there is a solution. Automatic generation of AI summaries is controlled by Gmail’s “smart features.” You (or an administrator of your managed account) can disable that. Open the app settings, select the account, and uncheck the smart features toggle.

For most people, Gmail’s smart features are enabled out of the box, but they’re off by default in Europe and Japan. When you disable them, you won’t see the automatic AI summaries, but there will still be a button to generate those summaries with Gemini. Be aware that smart features also control high-priority notifications, package tracking, Smart Compose, Smart Reply, and nudges. If you can live without all of those features in the mobile app, you can avoid automatic AI summaries. The app will occasionally pester you to turn smart features back on, though.

Real TikTokers are pretending to be Veo 3 AI creations for fun, attention


The turing test in reverse

From music videos to “Are you a prompt?” stunts, “real” videos are presenting as AI

Of course I’m an AI creation! Why would you even doubt it? Credit: Getty Images

Since Google released its Veo 3 AI model last week, social media users have been having fun with its ability to quickly generate highly realistic eight-second clips complete with sound and lip-synced dialogue. TikTok’s algorithm has been serving me plenty of Veo-generated videos featuring impossible challenges, fake news reports, and even surreal short narrative films, to name just a few popular archetypes.

However, among all the AI-generated video experiments spreading around, I’ve also noticed a surprising counter-trend on my TikTok feed. Amid all the videos of Veo-generated avatars pretending to be real people, there are now also a bunch of videos of real people pretending to be Veo-generated avatars.

“This has to be real. There’s no way it’s AI.”

I stumbled on this trend when the TikTok algorithm fed me this video topped with the extra-large caption “Google VEO 3 THIS IS 100% AI.” As I watched and listened to the purported AI-generated band that appeared to be playing in the crowded corner of someone’s living room, I read the caption containing the supposed prompt that had generated the clip: “a band of brothers with beards playing rock music in 6/8 with an accordion.”

@kongosmusicWe are so cooked. This took 3 mins to generate. Simple prompt: “a band of brothers playing rock music in 6/8 with an accordion”♬ original sound – KONGOS

After a few seconds of taking those captions at face value, something started to feel a little off. After a few more seconds, I finally noticed the video was posted by Kongos, an indie band that you might recognize from their minor 2012 hit “Come With Me Now.” And after a little digging, I discovered the band in the video was actually just Kongos, and the tune was a 9-year-old song that the band had dressed up as an AI creation to get attention.

Here’s the sad thing: It worked! Without the “Look what Veo 3 did!” hook, I might have quickly scrolled by this video before I took the time to listen to the (pretty good!) song. The novel AI angle made me stop just long enough to pay attention to a Kongos song for the first time in over a decade.

Kongos isn’t the only musical act trying to grab attention by claiming their real performances are AI creations. Darden Bela posted that Veo 3 had “created a realistic AI music video” over a clip from what is actually a 2-year-old music video with some unremarkable special effects. Rapper GameBoi Pat dressed up an 11-month-old song with a new TikTok clip captioned “Google’s Veo 3 created a realistic sounding rapper… This has to be real. There’s no way it’s AI” (that last part is true, at least). I could go on, but you get the idea.

@gameboi_pat This has got to be real. There’s no way it’s AI 😩 #google #veo3 #googleveo3 #AI #prompts #areweprompts? ♬ original sound – GameBoi_pat

I know it’s tough to get noticed on TikTok, and that creators will go to great lengths to gain attention from the fickle algorithm. Still, there’s something more than a little off-putting about flesh-and-blood musicians pretending to be AI creations just to make social media users pause their scrolling for a few extra seconds before they catch on to the joke (or don’t, based on some of the comments).

The whole thing evokes last year’s stunt where a couple of podcast hosts released a posthumous “AI-generated” George Carlin routine before admitting that it had been written by a human after legal threats started flying. As an attention-grabbing stunt, the conceit still works. You want AI-generated content? I can pretend to be that!

Are we just prompts?

Some of the most existentially troubling Veo-generated videos floating around TikTok these days center around a gag known as “the prompt theory.” These clips focus on various AI-generated people reacting to the idea that they are “just prompts” with various levels of skepticism, fear, or even conspiratorial paranoia.

On the other side of that gag, some humans are making joke videos playing off the idea that they’re merely prompts. RedondoKid used the conceit in a basketball trick shot video, saying “of course I’m going to make this. This is AI, you put that I’m going to make this in the prompt.” User thisisamurica thanked his faux prompters for putting him in “a world with such delicious food” before theatrically choking on a forkful of meat. And comedian Drake Cummings developed TikTok skits pretending that it was actually AI video prompts forcing him to indulge in vices like shots of alcohol or online gambling (“Goolgle’s [sic] New A.I. Veo 3 is at it again!! When will the prompts end?!” Cummings jokes in the caption).

@justdrakenaround Goolgle’s New A.I. Veo 3 is at it again!! When will the prompts end?! #veo3 #google #ai #aivideo #skit ♬ original sound – Drake Cummings

Beyond the obvious jokes, though, I’ve also seen a growing trend of TikTok creators approaching friends or strangers and asking them to react to the idea that “we’re all just prompts.” The reactions run the gamut from “get the fuck away from me” to “I blame that [prompter], I now have to pay taxes” to solipsistic philosophical musings from convenience store employees.

I’m loath to call this a full-blown TikTok trend based on a few stray examples. Still, these attempts to exploit the confusion between real and AI-generated video are interesting to see. As one commenter on an “Are you a prompt?” ambush video put it: “New trend: Do normal videos and write ‘Google Veo 3’ on top of the video.”

Which one is real?

The best Veo-related TikTok engagement hack I’ve stumbled on so far, though, might be the videos that show multiple short clips and ask the viewer to decide which are real and which are fake. One video I stumbled on shows an increasing number of “Veo 3 Goth Girls” across four clips, challenging in the caption that “one of these videos is real… can you guess which one?” In another example, two similar sets of kids are shown hanging out in cars while the caption asks, “Are you able to identify which scene is real and which one is from veo3?”

@spongibobbu2 One of these videos is real… can you guess which one? #veo3 ♬ original sound – Jett

After watching both of these videos on loop a few times, I’m relatively (but not entirely) convinced that every single clip in them is a Veo creation. The fact that I watched these videos multiple times shows how effective the “Real or Veo” challenge framing is at grabbing my attention. Additionally, I’m still not 100 percent confident in my assessments, which is a testament to just how good Google’s new model is at creating convincing videos.

There are still some telltale signs for distinguishing a real video from a Veo creation, though. For one, Veo clips are still limited to just eight seconds, so any video that runs longer (without an apparent change in camera angle) is almost certainly not generated by Google’s AI. Looking back at a creator’s other videos can also provide some clues—if the same person was appearing in “normal” videos two weeks ago, it’s unlikely they would be appearing in Veo creations suddenly.

There’s also a subtle but distinctive style to most Veo creations that can distinguish them from the kind of candid handheld smartphone videos that usually fill TikTok. The lighting in a Veo video tends to be too bright, the camera movements a bit too smooth, and the edges of people and objects a little too polished. After you watch enough “genuine” Veo creations, you can start to pick out the patterns.

Regardless, TikTokers trying to pass off real videos as fakes—even as a joke or engagement hack—is a recognition that video sites are now deep in the “deep doubt” era, where you have to be extra skeptical of even legitimate-looking video footage. And the mere existence of convincing AI fakes makes it easier than ever to claim real events captured on video didn’t really happen, a problem that political scientists call the liar’s dividend. We saw this when then-candidate Trump accused Democratic nominee Kamala Harris of “A.I.’d” crowds in real photos of her Detroit airport rally.

For now, TikTokers of all stripes are having fun playing with that idea to gain social media attention. In the long term, though, the implications for discerning truth from reality are more troubling.

google-and-doj-tussle-over-how-ai-will-remake-the-web-in-antitrust-closing-arguments

Google and DOJ tussle over how AI will remake the web in antitrust closing arguments

At the same time, Google is seeking to set itself apart from AI upstarts. “Generative AI companies are not trying to out-Google Google,” said Schmidtlein. Google’s team contends that its actions have not harmed any AI products like ChatGPT or Perplexity, and at any rate, they are not in the search market as defined by the court.

Mehta mused about the future of search, suggesting we may have to rethink what a general search engine is in 2025. “Maybe people don’t want 10 blue links anymore,” he said.

The Chromium problem and an elegant solution

At times during the case, Mehta has expressed skepticism about the divestment of Chrome. During closing arguments, Dahlquist reiterated the close relationship between search and browsers, reminding the court that 35 percent of Google’s search volume comes from Chrome.

Mehta now seems more receptive to a Chrome split than before, perhaps in part because the effects of the other remedies are becoming so murky. He called the Chrome divestment “less speculative” and “more elegant” than the data and placement remedies. Google again claimed, as it has throughout the remedy phase, that forcing it to give up Chrome is unsupported in the law and that Chrome’s dominance is a result of innovation.

Break up the company without touching the sides and getting shocked!

Even if Mehta leans toward ordering this remedy, Chromium may be a sticking point. The judge seems unconvinced that the supposed buyers—a group which apparently includes almost every major tech firm—have the scale and expertise needed to maintain Chromium. This open source project forms the foundation of many other browsers, making its continued smooth operation critical to the web.

If Google gives up Chrome, Chromium goes with it, but what about the people who maintain it? The DOJ contends that it’s common for employees to come along with an acquisition, but that’s far from certain. There was some discussion of ensuring a buyer could commit to hiring staff to maintain Chromium. The DOJ suggests Google could be ordered to provide financial incentives to ensure critical roles are filled, but that sounds potentially messy.

A Chrome sale seems more likely now than it did earlier, but nothing is assured yet. Following the final arguments from each side, it’s up to Mehta to mull over the facts before deciding Google’s fate. That’s expected to happen in August, but nothing will change for Google right away. The company has already confirmed it will appeal the case, hoping to have the original ruling overturned. It could still be years before this case reaches its ultimate conclusion.
