Vast has revealed its astronaut flight suit, a two-piece outfit designed to be worn both on and off the planet. The company also certified a custom-Swiss wristwatch for use aboard its upcoming Haven-1 space station.

"Over the last two decades on the International Space Station, astronauts have moved away from wearing flight suits every day," Drew Feustel, Vast's lead astronaut and former NASA mission specialist who spent 225 days in space, said in a statement. "The environment has become safer and more like how we work on Earth."

Since the launch of DeepSeek—a Chinese model that OpenAI claimed was trained using outputs from its models—other AI firms have accused global rivals of using a method called distillation to steal their IP. In January, Google claimed that "commercially motivated" actors not limited to China attempted to clone its Gemini AI chatbot by promoting the model more than 100,000 times in bids to train cheaper copycats. The next month, Anthropic accused Chinese firms DeepSeek, Moonshot, and MiniMax of using the same tactic to generate "over 16 million exchanges with Claude through approximately 24,000 fraudulent accounts." Also in February, OpenAI confirmed that most attacks it saw originated from China.

For the US, these distillation attacks supposedly threaten to help China quickly catch up in the AI race. In a memo that FT reviewed, the director of the White House Office of Science and Technology Policy, Michael Kratsios, warned that "the US government has information indicating that foreign entities, principally based in China, are engaged in deliberate, industrial-scale campaigns to distill US frontier AI systems."

But then the reality of working with them set in. It was hard to get a pure population of metallic or semiconducting forms. Synthesis techniques tended to produce a tangle of mostly short nanotubes; those that extended for more than a couple of centimeters remain rare. And while the metallic version offered little resistance to carrying electric current, it was hard to send many electrons down the nanotube.

Materials scientists, however, are a stubborn bunch, and they're still trying to get them to work. Today's issue of Science includes a paper describing the addition of a chemical to carbon nanotube bundles to boost their ability to carry current to levels closer to those of copper. While the more conductive nanotubes weren't stable, the discovery may point the way toward something with a longer shelf life.

The gravitational constant, affectionally known as "Big G," is one of the most fundamental constants of our universe. Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time. Physicists have a solid ballpark figure for the value of Big G, but they've been trying to measure it ever more precisely for more than two centuries, each effort yielding slightly different values. And we do mean slight: The values vary by roughly one part in 10,000.

Still, other fundamental constants are known much more precisely. So Big G is the black sheep of the family and a point of frustration for physicists keen on precision metrology. The problem is that gravity is so weak, by far the weakest of the four fundamental forces, so there is significant background noise from the gravitational field of the Earth (aka "little g"). That weakness is even more pronounced in a laboratory.

In the latest effort to resolve the issue, scientists at the National Institute of Standards and Technology (NIST) spent the last decade replicating one of the most divergent recent experimental results. The group just announced their results in a paper published in the journal Metrologia. It does not resolve the discrepancy, but it gives physicists one more data point in their ongoing quest to nail down a more precise value for Big G.

Kyber, as the ransomware is called, has been around since at least last September and quickly attracted attention for the claim that it used ML-KEM, short for Module Lattice-based Key Encapsulation Mechanism and is a standard shepherded by the National Institute of Standards and Technology. The Kyber ransomware name comes from the alternate name for ML-KEM, which is also Kyber. For the rest of the article, Kyber refers to the ransomware; the algorithm is referred to as ML-KEM.

It's all about marketing

ML-KEM is an asymmetric encryption method for exchanging keys. It involves problems based on lattices, a structure in mathematics that quantum computers have no advantage in solving over classic computing. ML-KEM is designed to replace Elliptic Curve and RSA cryptosystems, both of which are based on problems that quantum computers with sufficient strength can tackle.

The exchanges mark a rare instance in which Kennedy's dismissal of germ theory has been raised in such a high-profile public setting, in this case, a hearing of the Senate Committee on Health, Education, Labor, and Pensions. Kennedy, who has no background in science, medicine, or public health, is well known as an ardent anti-vaccine activist and peddler of conspiracy theories. But his startling rejection of a cornerstone theory in biomedical science has mostly been underreported.

As Ars Technica reported last year, Kennedy wrote about his germ theory denialism explicitly in his 2021 book The Real Anthony Fauci. In it, Kennedy maligns germ theory as a tool of pharmaceutical companies, scientists, and doctors to promote the use of modern medicines. Instead of accepting germ theory, Kennedy promotes a concept akin to the discarded terrain theory, in which diseases stem not from germs, but from imbalances in the body's inner "terrain." Those imbalances are claimed to be caused by poor nutrition and exposure to environmental toxins and stressors. (In his book, Kennedy erroneously labels this as "miasma theory," but that is a different theory that suggests diseases derive from breathing bad air, vapors, or mists from decaying or corrupting matter. The idea was supplanted by germ theory, while terrain theory was never widely accepted.)

Over the last few months, the Mac mini and the Mac Studio have gradually become harder to buy. The 512GB M3 Ultra Mac Studio was removed from Apple's website, and other models of both desktops have seen their ship times slip from days to weeks to months. In the last couple of weeks, several other configurations of Mac mini and Studio have begun showing up as "currently unavailable" on Apple's website, which virtually never happens even when Apple is planning an imminent hardware refresh.

This week (as spotted by MacRumors), the baseline $599 M4 Mac mini, which offers 16GB of RAM and 256GB of storage, earned the "currently unavailable" label for the first time.

Gen. Stephen Whiting didn't name the system, but he was almost certainly referring to a Russian military program named Nivelir, which has launched four satellites shadowing US spy satellites owned by the National Reconnaissance Office in low-Earth orbit. After reaching orbit, the Nivelir satellites have released smaller ships to start their own maneuvers, and at least one of those lobbed a mystery object at high velocity during a test in 2020. US analysts concluded this was a projectile that could be fired at another satellite.

US officials have compared the Nivelir architecture to a Matryoshka doll, or a Russian nesting doll, with an outer shell concealing smaller, unknown figures inside.

Vulnerable users hoping to evade law enforcement surveillance often use encrypted apps like Signal to communicate sensitive information. That's why users felt blindsided when 404 Media reported that Apple was unexpectedly storing push notifications displaying parts of encrypted messages for up to a month. This occurred even after the message was set to disappear and the app itself was deleted from the device.

404 Media flagged the issue after speaking to multiple people who attended a hearing where the FBI testified that it "was able to forensically extract copies of incoming Signal messages from a defendant’s iPhone, even after the app was deleted, because copies of the content were saved in the device’s push notification database." The shocking revelation came in a case that 404 Media noted was "the first time authorities charged people for alleged 'Antifa' activities after President Trump designated the umbrella term a terrorist organization."

It also has an unusual history that began when NASA's planning intersected with surplus spy hardware.

In from the cold

Many of the gases in our atmosphere absorb infrared wavelengths, contributing to the greenhouse effect that has helped keep the planet habitable for us. But that effect also makes infrared astronomy from Earth extremely difficult. That's unfortunate, as a number of important phenomena, from the earliest galaxies to the features of exoplanet atmospheres, are only detectable at infrared wavelengths. There have been a number of infrared-specific telescopes put into space, notably the Spitzer, one of the original suite of Great Observatories.

The 2027 BMW 7 Series is a refresh of the seventh-generation G70 version that arrived in the United States as a 2023 model. But the changes are much more extensive than the typical refresh, or “life cycle impulse” (LCI) in BMW-speak. That’s because the updated 7 Series borrows tech and styling elements from the new Neue Klasse—the family of EVs that so far includes the iX3 crossover and i3 sedan.

This hulking sedan still lacks the grace of its E3 and E23 ancestors, but the infusion of Neue Klasse details and other tweaks definitely help. The rear bumper has a cleaner look, as does the front end, which has a simplified version of the previous split-lighting arrangement of daytime running lights above rectangular headlights nestled in coves that also house the intakes for the front-wheel air curtains.

As tech companies race to secure massive power deals to build out hundreds of data centers across the country, these projects represent just the tip of the iceberg when it comes to the potential climate cost of the AI boom.

The infrastructure on this list of large natural gas projects reviewed by WIRED is being developed to largely bypass the grid and provide power solely for data centers, a trend known as behind-the-meter power. As data center developers face long waits for connections to traditional utilities, and amid mounting public resistance to the possibility of higher energy bills, making their own power is becoming an increasingly popular option. These projects have either been announced or are under construction, with companies already submitting air permit application materials with state agencies.

The first warning of such a crypto scam came from the Greek maritime risk management company MARISKS on April 20, according to Reuters. The company alerted shipowners that scammers posing as Iranian authorities had sent messages to shipping companies asking for “transit fee” payments in bitcoin or tether.

That may be particularly confusing for shipping companies because of how Iran has asserted control over the Strait of Hormuz—a vital shipping channel and maritime chokepoint that normally allows Persian Gulf countries to provide one-fifth of the world’s oil and liquefied natural gas supply. Iranian authorities have demanded cryptocurrency payments from oil tankers to pass through the waterway and required ships to follow a route near Iran’s coastline to undergo inspection.

Revenue increased by 16 percent year over year to $22.4 billion. Automotive revenue grew by the same percentage to $16.2 billion, and Tesla saw a 42 percent increase in services (like Supercharger fees) and other revenue. But its energy storage business shrank in Q1, and revenues from this division fell by 12 percent to $2.4 billion.

An operating margin of 4.2 percent is far from the double-digit margins Tesla once boasted. But things were twice as bad in 2025. Although the company brought in more money from automotive sales, it only made $380 million from selling regulatory credits, compared to $595 million in Q1 2025. It also made less money from leasing. Operating expenses rose due to spending on AI and part of the $1 trillion compensation package that shareholders approved in November for CEO Elon Musk.

Our approach comes from two convictions: that AI cannot replace human insight, creativity, and ingenuity, and that these tools, used well, can help professionals do better work. From those starting points, it was always clear what we wouldn't allow. AI would not become the author, the illustrator, or the videographer. These tools are best used by professionals in the service of their profession, not as a clever end run around it, and certainly not as a path to eventually replacing it.

The short version: Ars Technica is written by humans. Our reporting, analysis, and commentary are human-authored. Where we use AI tools in our workflow, we use them with standards and oversight, and humans make every editorial decision. Our policy covers how we handle text, research, source attribution, images, audio, and video.

"Unless restrained by this Court, Nintendo stands to recover the same tariff payments twice—once from consumers through higher prices and again from the federal government through tariff refunds, including interest paid by the government on those funds," said the lawsuit filed in US District Court for the Western District of Washington. "Nintendo has made no legally binding commitment to return tariff-related overcharges to the consumers who actually paid them. This lawsuit seeks to prevent that unjust result."

The plaintiffs, California resident Gregory Hoffert and Washington resident Prashant Sharan, "paid retail prices for those goods that were increased by Nintendo to account for the tariffs imposed on imported products," and "would not have paid those higher prices absent the unlawful tariffs and Nintendo’s pass-through of those tariffs to consumers," said the complaint filed by the Emery | Reddy, PC law firm.

In a Congressional hearing Tuesday, Kennedy refused to commit to supporting evidence-based vaccine policy from the next director of the Centers for Disease Control and Prevention. At the same time, he refused to say that he wouldn't interfere with the agency's recommendations.

Last week, Trump nominated Erica Schwartz to be the next CDC director, a role that requires Senate confirmation. Schwartz is a respected physician and former public health official who has championed the use of vaccines during her distinguished career. Outside experts were pleasantly surprised by the uncontroversial choice but wary of her ability to implement evidence-based policy under Kennedy. Last year, Kennedy—who has no medical, scientific, or public health background—ousted the previous Senate-confirmed director, Susan Monarez, who was, like Schwartz, a well-qualified and respected pick for the role. Monarez testified that she was pushed out for refusing to rubber-stamp vaccine recommendations from Kennedy's hand-selected anti-vaccine advisors. Monarez lasted as CDC director for just 29 days.

This is because Orion largely communicated with Earth via radio waves, picked up by large dishes sprinkled around the world. This is pretty much the same way the Apollo spacecraft talked to Earth more than half a century ago.

However, unlike Apollo, the astronauts on Orion would periodically send batches of much higher-resolution data, including the stunning photographs of the far side of the Moon and the Solar eclipse observed from there. This was made possible by optical laser communications, and not just those built by NASA. The mission included a commercial component that could pave the way for vastly more data returning to Earth from space than ever before.

The software maker said Tuesday evening that the vulnerability, tracked as CVE-2026-40372, affects versions 10.0.0 through 10.0.6 of the Microsoft.AspNetCore.DataProtection NuGet, a package that’s part of the framework. The critical flaw stems from a faulty verification of cryptographic signatures. It can be exploited to allow unauthenticated attackers to forge authentication payloads during the HMAC validation process, which is used to verify the integrity and authenticity of data exchanged between a client and a server.

Beware: Forged credentials survive patching

During the time users ran a vulnerable version of the package, they were left open to an attack that would allow unauthenticated people to gain sensitive SYSTEM privileges that would allow full compromise of the underlying machine. Even after the vulnerability is patched, devices may still be compromised if authentication credentials created by a threat actor aren’t purged.

Users took to Reddit and X to point out that Anthropic's pricing page for Claude explicitly showed Claude Code as not supported in the Pro plan. (It remained in the $100/month+ Max plan.) Some new users signing up for Pro subscriptions were unable to access Claude Code. Meanwhile, existing subscribers saw no interruption.

After speculation and frustration spread, Anthropic's head of growth, Amol Avasare, took to social media to clarify that this was a "small test on ~2% of new prosumer signups." As for the reasoning, he explained:
