Researchers have found a never-before-seen piece of macOS malware that combines a series of clever tradecraft to infect Macs with stealthy, custom-developed credential-stealing code.

The malware is delivered in two stages. The first is distributed in a disk image that masquerades as Maccy, a clipboard manager for Macs. It’s compiled as AppleScript that is notable for the way it delivers the second stage. The malware is named PamStealer because the Rust-written infostealer uses the Pluggable Authentication Modules interface built into macOS to validate the target’s login password before sending it to an attacker-controlled server.

A quieter execution chain

The use of both disk image and AppleScript is common in malware for Macs. More unusual is the way PamStealer combines them to gain stealth. When the AppleScript is double-clicked, it’s opened in the macOS Script Editor, where the malicious functionality is buried deep within the file.

A long-standing ban on commercial supersonic flights over the United States would be overturned in a new rule proposed by the US Federal Aviation Administration. That could pave the way for the possible return of commercial supersonic airliners—as long as such aircraft can reduce the ground-level impacts of their sonic booms.

The FAA originally banned overland supersonic flights by civil aircraft in 1973, following US military tests involving supersonic flights over US cities such as Oklahoma City, Chicago, and St. Louis in the 1960s. But the Trump administration has championed the repeal of the ban to pave the way for supersonic airliners that could operate without disruptive sonic booms. So the FAA’s new rulemaking action on June 30, 2026, follows the direction of an executive order issued by President Trump on June 6, 2025.

The newly proposed rule would replace the 53-year prohibition with an interim “noise-based” certification standard requiring any sonic boom overpressure at the surface to be kept below 0.11 pounds per square foot. That proposed standard is based on the Colorado-based startup Boom Supersonic having demonstrated quiet Mach cutoff flights with its XB-1 aircraft—harnessing specific atmospheric conditions while flying just beyond supersonic speeds at higher altitudes so that the aircraft’s shockwaves are refracted upward into the atmosphere rather than traveling to the ground.

This week Ars hosted a live discussion with two space industry experts about the aftermath of the catastrophic explosion of the New Glenn rocket in late May.

Along with Ars Technica Space Editor Eric Berger; the director of research at Quilty Space, Caleb Henry; and the host of the Main Engine Cut Off podcast, Anthony Colangelo, spoke about various topics. Chief among them was the implications of this failure for NASA's attempt to land humans on the Moon for the Artemis IV mission. Blue Origin and SpaceX are both building landers to support this goal and the rockets to deliver them to the Moon.

During the conversation, Berger reported that the current Blue Origin "architecture" for a human mission would require four launches of new variant of the New Glenn rocket, known as 9x4, because it has nine first stage engines, and four upper stage engines. This is a more powerful version than the "7x2" variant that exploded a little more than a month ago. Blue Origin has not set a target date for the 9x4 rocket's debut, but some sources have indicated the company is targeting late 2027 or early 2028.

When Plex launched in 2012, it sold lifetime access to its media server software for $75. In 2014, Plex raised the price to be more sustainable for the company, it said, and for years, Lifetime Plex Passes cost $120. Even the pricier $250 rate, which Plex offered from March 2025 until yesterday, was a steal compared to what $250 buys you at Plex now: a five-year subscription.

As first spotted by The Desk, Plex yesterday launched the five-year Plex Pass. It comes alongside Lifetime Pass prices increasing to $750 yesterday, a change that Plex announced in May and, in a blog post update this week, said: “reflects the real, ongoing value of the software and our commitment to building, improving, and supporting Plex for years to come.”

The stark change in what $250 can get you at Plex is indicative of the company’s financial goals. Plex hasn’t yet announced profitability and has raised $87.6 million over nine rounds of funding, per CB Insights. The company is looking to squeeze more money out of its users and price its media server business higher.

Amid disease surveillance for the ongoing Ebola outbreak, Ugandan health authorities identified a case of Marburg virus disease in a one-and-a-half-year-old child, who has died, according to Africa Centers for Disease Control and Prevention. But Ugandan health officials appear reluctant to publicly disclose information about the case and its context.

Marburg virus is related to Ebolaviruses and causes similar hemorrhagic disease. Its transmission routes and prevention measures are likewise similar.

On Wednesday, Africa CDC told Reuters that no contacts of the deceased toddler had developed symptoms, and there were no other current active cases in the country, citing Ugandan health authorities. But when Reuters reached out to Uganda's health ministry, a spokesperson said he was not aware of a Marburg outbreak.

Understanding the origin of life requires addressing a collection of overlapping scientific questions. We've made a lot of progress toward explaining how simple chemicals present on an early Earth built the complex molecules used by life and how some of those chemicals built the first genetic/catalytic molecules. But we're much further from understanding a key conundrum: How did membranes end up surrounding the first cells?

It's relatively easy to make membranes spontaneously form in water, and they'll enclose anything dissolved in that water, including nucleic acids. But the membranes then cut their interior off from everything else in the solution. Any interesting chemical reactions enclosed there would eat through the raw materials and grind to a halt.

Now, a lab at the University of Minnesota has announced that it has developed a simplified system in which a membrane encloses some genetic material but can continually import new materials supplied to it. The system also spontaneously divides, producing a few generations of "offspring" before things start failing. It's still extremely dependent upon human intervention, but it might provide a new avenue to explore questions about the origin of life and what a truly minimalistic form of life might look like.

Back in 2018, Google was handed a record-setting 4.34 billion-euro ($4.9 billion) fine in Europe for abusing its monopoly on Android. The company has spent the intervening years challenging that decision, but the continent's highest court has put a stop to that. The Court of Justice of the European Union has affirmed the penalty, meaning Google is out of options.

Google's fight may not have turned out the way the company wanted, but it wasn't for nothing. The initial amount was trimmed slightly by a lower court in 2022, bringing the total to a still record-setting 4.1 billion euros ($4.7 billion). And that looks like the amount Google will have to pay since there are no further avenues for appeal.

The fine stems from the way Google bundles apps and services with Android phones. The EU took issue with Google search and Chrome being the default options on Android. Even devices made by other companies, such as Samsung and Xiaomi, include Google apps as the default per the Android licensing agreement, giving Google an unfair advantage, according to European antitrust regulators. This is not to be confused with a 2.95 billion euro ($3.45 billion) fine against Google's advertising monopoly issued by the European Union last year.

OpenAI CEO Sam Altman is reportedly in active talks with the Trump administration about the US potentially acquiring a 5 percent stake in the leading AI firm.

Insider sources told the Financial Times that these talks are in “early stages,” but Altman “has argued that giving the public a financial stake in the company is the best way to share the upside of AI.”

Donald Trump favors the idea, and his administration has reportedly been talking to several AI firms about the possibility. According to FT’s sources, other companies approached to share similar stakes include Google and Meta.

Ahead of a July 2 deadline to submit public comments, advocates are warning the Federal Trade Commission that it must keep close watch over Elon Musk’s X and firmly reject a recent bid to end the agency’s ongoing audits of the platform’s data handling.

Last month, the FTC posted a notice explaining that X had argued that an FTC order was no longer necessary due to changes Musk had made to the platform.

The initial order came as a penalty after the FTC found that a coding error had caused then-Twitter to improperly share users’ contact information for ad targeting that had initially been submitted for two-factor authentication. Under the order, X is subjected to costly independent audits, and the FTC has authority to demand documents to ensure compliance with data privacy laws without taking additional legal action.

If the car-buying public had qualms about Tesla, it appears to have gotten over them. This morning, the automaker released its sales and production numbers for the second quarter of the year. And if you're a fan of activist CEO Elon Musk, it's good news, as April, May, and June were great months for the company. In total, Tesla sold 480,126 EVs during Q2, a 25 percent year-over-year increase.

As expected, the Model 3 and Y make up the vast majority of sales; despite its size, Tesla still only mass-produces these two models, which accounted for 467,762 deliveries, a 25.2 percent increase compared to Q2 last year. The remaining 12,364 vehicles—a 19 percent increase compared to the same quarter in 2025—were a mix of the now-discontinued Models S and X and the controversial Cybertruck, which is only sold in North America and the Middle East.

Better news for Tesla fans is that the company appears to be getting a handle on its overproduction problem. As we noted when it published its Q1 2026 results in March, Tesla had a growing inventory problem, repeatedly building more cars each month than it could sell. But total production for Q2 was 451,758 cars; this is a 10 percent increase year over year but also nearly 30,000 fewer cars than it sold this quarter.

A 56-year-old woman was admitted to a hospital with an array of alarming symptoms that were only getting worse. For eight weeks, she had a painful "pins and needles" feeling that started in both of her feet and then began working its way up her legs. By the time she arrived at the hospital, she was unable to feel her feet on the ground. She frequently stumbled and clutched at walls to stay up. But the tingling numbness was moving into her hands, too. Then came neurological symptoms. She told her doctors about short-term memory problems and difficulty concentrating. She was irritable and had no appetite. She was experiencing heart palpitations, too.

According to a case report this week in the New England Journal of Medicine, her doctors looked through her medical history for clues, finding nothing that immediately stood out. She had high blood pressure, a history of anxiety and depression, and hypothyroidism (an underactive thyroid). They did notice that, although she had managed the thyroid problem for more than a decade at the same dose of medication, she had been switched four weeks earlier to a stronger dose. But the dosage change didn't immediately raise any red flags.

She also had a history of hip problems. Twenty years before, she had a hip replacement that stemmed from an injury she sustained in a car crash ten years before that. While more than 90 percent of hip replacements last at least 30 years, the woman's started failing her after 19.

Google reported that its annual electricity consumption rose by 37 percent in 2025—the largest increase in the company’s history as Silicon Valley’s AI data center buildout continues. But the tech giant says it kept operational carbon emissions down by continuing to purchase massive amounts of clean energy.

The company’s latest sustainability report acknowledges that Google’s total electricity usage has increased by more than 250 percent since 2019, which the company attributed to ongoing growth in Google Cloud, YouTube video streaming, and data center construction and operations supporting various AI products and services. The unprecedented 37 percent annual increase is part of an ongoing trend, given how Google’s total electricity consumption also grew by 27 percent in 2024.

“While the path to achieving our climate ambitions will not be linear—given our AI infrastructure buildout is currently accelerating faster than the grid is decarbonizing—we remain focused on scaling abundant and affordable clean power globally and progressing technological innovations that drive down emissions across our operations and the broader industry,” according to the Google sustainability report.

Near the end of May, the Office of Management and Budget (OMB) proposed a new rule that would govern how the federal government handles the grants it issues, including those that fund the vast majority of scientific research in the US.

If formalized, the rule would make political priorities the prime determinant of what science gets funded and sideline the opinions of scientific experts. Grants could be canceled due to political whims, and new layers of bureaucracy would inhibit basic scientific activities like publishing papers and attending conferences. Unlike the executive orders it echoes, it would have the force of law behind it and be significantly harder to challenge in court.

Before coming into force, however, the proposal must go through a process that includes public feedback and (potentially) changes in response. The deadline for that feedback—Monday, July 13—is rapidly approaching.
