SpaceX described its traditional space launch and satellite business as playing a supporting role to its fledgling AI business in financial disclosures that preceded an expected initial public offering of company stock. That stems from SpaceX having formally acquired Musk’s company xAI earlier this year—the SpaceXAI division now oversees the Grok AI models and the associated Grok chatbot previously developed by xAI.

The SpaceX S-1 filing claimed that the company has “the largest actionable total addressable market in human history” and highlighted AI as representing most of that opportunity at an estimated $26.5 trillion market—a number that comes close to rivaling US nominal GDP that stood at nearly $32 trillion in the first quarter of 2026.

"California requires AT&T to spend $1 billion each year to maintain a century-old telephone network that almost no one uses," AT&T said in a lawsuit filed in US District Court for the Southern District of California. "The copper wires that once served every home now serve just three percent of households in AT&T’s California territory, with consumers fleeing every day to modern broadband services that are more affordable, reliable, and energy-efficient."

In June 2024, the California Public Utilities Commission (CPUC) rejected AT&T’s request to eliminate the Carrier of Last Resort (COLR) obligation that requires it to provide landline telephone service to any potential customer in its service territory. AT&T has said it's received relief from COLR obligations in 20 of the 21 states in its wireline service territory, all except California.

Tidal locking means that you no longer have day- and night-side temperature differences sweeping across the planet. “We wanted to understand the atmospheres of such planets,” Mukherjee says. “Are they static or dynamic? Do they have winds? Do they have clouds?” His team found that, on WASP-94A b, it’s cloudy in the morning, but the skies are clear in the evening. The fact that we didn’t know this already means we might have gotten the chemistry of this and many other exoplanets surprisingly wrong.

Averaged atmospheres

WASP-94A b has a mass slightly below half of Jupiter but has a diameter that’s over 70 percent wider. “This means the planet has low density, and its atmosphere extends further out into space, which makes it easier to observe,” Mukherjee explains. When astronomers study atmospheres like this, they usually rely on transmission spectroscopy. By analyzing the spectrum of light filtering through the planet’s atmosphere as it crosses in front of its star, they can figure out its chemical composition.

When the action film Top Gun hit the big screen in 1986, critical reviews were mixed, but audiences were thrilled. The film racked up $358 million globally, making it the highest-grossing film of that year. Its success spawned a few video games and a critically acclaimed blockbuster 2022 sequel, Top Gun: Maverick, and the eye-popping flight sequences definitely boosted enlistment numbers for the US Navy. Those scenes are still the best thing about Top Gun, 40 years later.

(Spoilers below because it's been 40 years.)

The film was inspired by a 1983 article in California magazine detailing the lives of fighter pilots at Naval Air Station Miramar in San Diego (aka "Fightertown USA") and featuring plenty of aerial photography alongside the text. Producers Jerry Bruckheimer and Don Simpson tapped Jim Cash and Jack Epps Jr. to write the screenplay, with Epps sitting in on declassified classes at the academy and even taking a flight aboard an F-14.

For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.

In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.

The announcement by the commerce department that it had signed letters of intent with nine companies—including GlobalFoundries and IBM—sent shares in quantum specialists soaring on Thursday.

Both IBM, which is set to get $1 billion, and GlobalFoundries, which will receive $375 million, were up more than 6 percent in pre-market trading. D-Wave Quantum, an awardee that was taken public in 2022 by Emil Michael—now a top Pentagon official—was up more than 20 percent.

Instead, they were seduced into buying a car with far too big a battery, no doubt as a result of generous incentives, the theory goes. And if those drivers aren't going to plug in and therefore enjoy at least some entirely electric driving, they should have bought a parallel hybrid instead, which often delivers better efficiency than a PHEV with an empty battery, at a significantly lower price.

But what if that take is wrong? As it turns out, there's some more evidence that PHEV drivers do in fact plug in their plug-ins, and the latest data point is from one of the most prolific PHEV pushers: Toyota.

MUNICH—Headlight technology in the US is about to get smarter. When Audi's Q9 SUV goes on sale here later this year, it will feature the automaker's latest adaptive beam headlights, which manage the nifty trick of providing better, brighter illumination while minimizing glare for both the driver and other road users. Such technology is old hat to our European readers, but it's finally debuting on our roads after years of lobbying and intensive, lengthy testing to satisfy the new federal regulations. And after trying out the headlights during a recent trip to Europe, I can say, "It's about time."

Despite America's reputation as an innovation powerhouse, we have lagged behind Europe and Japan in automotive lighting technology for decades, thanks to 1960s-era regulations that allowed only low- and high-beam headlights, nothing else. For years, OEMs like Audi, BMW, Mercedes-Benz, Toyota, and Volvo lobbied the National Highway Traffic Safety Administration to allow them to bring more modern technology to these shores to no avail.

At first, it was laser high beams, which could project their beams much farther down the road than conventional halogen or xenon lights. Lasers are cool, but adaptive driving beam technology is even cooler. Each headlight is actually a multipixel LED, and by turning some of those pixels off, the headlight beam can be shaped to mask the light to selectively dim oncoming vehicles instead of switching to low beams.

According to The Washington Post, five people close to the Ebola response said that, over the weekend, the Trump administration resisted allowing the return of Peter Stafford, a 39-year-old surgeon working in the Democratic Republic of the Congo amid a raging Ebola outbreak. The resistance allegedly delayed Stafford's evacuation and care, risking his health, as experts note that early treatment is critical for Ebola, which can turn deadly in days.

On Monday, the Centers for Disease Control and Prevention said Stafford had developed symptoms over the weekend and tested positive for Ebola late Sunday. In a press briefing on Wednesday, Satish Pillai, the CDC's incident response manager for the Ebola outbreak, said Stafford had arrived in Germany and is in stable condition. His wife, Rebekah Stafford—also a doctor who was exposed to the virus in DRC but is asymptomatic—along with the couple's four children, have been flown to Germany as well.

The Psyche mission launched more than two-and-a-half years ago, in October 2023, from Kennedy Space Center, Florida, to kick off a journey of some 2.2 billion miles (3.6 billion km) to reach its unexplored namesake, the asteroid Psyche. The robotic research mission got an initial lift from a powerful SpaceX Falcon Heavy rocket. It uses plasma engines to gradually build up the impulse needed to reach its destination in the asteroid belt, between the orbits of Mars and Jupiter.

A flyby of Mars last Friday gave the spacecraft its most significant boost since launch. Navigators at NASA's Jet Propulsion Laboratory in California set up the spacecraft for a course taking it 2,864 miles (4,609 km) from the Martian surface, well above the planet's tenuous atmosphere. Psyche used Martian gravity like a slingshot to gain enough speed to reshape its orbit around the Sun, putting the probe on a path to intercept its asteroid target.

No doubt buoyed by all the positive advance reviews on social media, Amazon MGM Studios has released one last trailer for Masters of the Universe, and it comes in strong with the 1980s nostalgia, chock-full of Easter eggs to delight Ars readers of a certain age.

Directed by Travis Knight (Bumblebee, Kubo and the Two Strings), the film is a reboot of sorts of the He-Man and the Masters of the Universe series, its spinoff, She-Ra: Princess of Powers, and the many, many other offshoots of this hugely popular Mattel franchise. Per the official premise:

In Masters of the Universe, Director Travis Knight brings the legendary franchise back to the big screen in this epic live-action adventure. After being separated for 15 years, the Sword of Power leads Prince Adam (Nicholas Galitzine) back to Eternia where he discovers his home shattered under the fiendish rule of Skeletor (Jared Leto). To save his family and his world, Adam must join forces with his closest allies, Teela (Camila Mendes) and Duncan/Man-At-Arms (Idris Elba), and embrace his true destiny as He-Man — the most powerful man in the universe.

In addition to Galitzine, Mendes, Elba, and Leto, the cast includes Alison Brie as Professor Evelyn Powers (aka Evil-Lyn); Morena Baccarin as the Sorceress of Castle Grayskull; Jóhannes Haukur Jóhannesson as Malcolm/Fisto; James Purefoy and Charlotte Riley as King Randor and Queen Marlena; Sasheer Zamata as Suzie, Adam/He-Man’s BFF on Earth; Kristen Wiig as Roboto; James Wilkinson as Mekaneck; Jon Xue Zhang as Ram-Man; Kojo Attah as the bounty hunter Tri-Klops; Sam C. Wilson as cyborg/weapons expert Kronis/Trap-Jaw; Hafþór Júlíus Björnsson as Goat Man; Robert Towers as Karg; and Christian Vunipola as Adam's roommate on Earth, Hussein.

Fittingly, then, Mercedes brought out its F1 team’s personnel, as George Russell presented the new car while Toto Wolff and Kimi Antonelli watched from the makeshift grandstands. Hollywood celebs ran the gamut, from Brad Pitt—who drove one GT onto the bridge—to Jacob Elordi and Kevin Hart, while Blink 182 played a surprisingly sarcastic mini set. All of the above may mean less to potential GT buyers than performance metrics and pricing when the 2027 model year comes along, but it only serves to prove just how big a deal Mercedes-AMG believes this will be.

A new look

In person, the new GT bears almost no resemblance to any of Benz’s prior EVs. No more bulbous, nautical EQS shapes or minorly smoothed over boxy G-Wagen aesthetic. The new design is more aided by digital renderings and iterative algorithms, especially the jutting front grille, reclined headlights, and Kamm-tail rear end—a bit of Aston Martin fore and aft. From the profile view, the proportions fit somewhere between a Porsche Panamera or Taycan, low-slung and slippery for ideal aerodynamic efficiency.

AMD may have something on the horizon for people who are looking to stretch their current PC (and its DDR4 RAM kit) just a little further. Leaks spotted by Tom's Hardware point to the existence of an "AMD Ryzen 7 5800X3D 10th Anniversary Edition," a re-release of a 4-year-old out-of-circulation CPU that might nevertheless be an upgrade for people with older Ryzen CPUs in Socket AM4 motherboards.

The "X3D" in the chip's name signifies that it comes with 64MB of extra L3 cache stacked on top of the main CPU die, bringing the total amount of L3 cache to 96MB. Workloads that benefit from extra cache—including most games—will perform much better on the 5800X3D than they do on the vanilla Ryzen 7 5800X.

The proof-of-concept code exploits the Browser Fetch programming interface, a standard that allows long videos and other large files to be downloaded in the background. An attacker can use the exploit to create a connection for monitoring some aspects of a user’s browser usage and as a proxy for viewing sites and launching denial-of-service attacks. Depending on the browser, the connections either reopen or remain open even after it or the device running it has rebooted.

Unfixed for 42 months (and counting)

The unfixed vulnerability can be exploited by any website a user visits. In effect, a compromise amounts to a limited backdoor that makes a device part of a limited botnet. The capabilities are limited to the same things a browser can do, such as visit malicious sites, provide anonymous proxy browsing by others, enable proxied DDoS attacks, and monitor user activity. Nonetheless, the exploit could allow an attacker to wrangle thousands, possibly millions, of devices into a network. Once a separate vulnerability becomes available, the attacker could use it to then compromise all those devices.

The remarks came on May 19 as Trump gave reporters a personal tour of the ballroom project that has already involved the demolition of the White House mansion’s East Wing. The president spoke of installing a rooftop drone base “for unlimited numbers of drones” operated by the US military as a “drone port that would protect all of Washington,” according to Reuters. He also highlighted a ballroom roof made from “impenetrable steel” that would supposedly be “drone-proof” against potential drone strikes.

To pay for such measures, Trump has been urging Republican lawmakers in the US Congress to approve $1 billion in taxpayer funding to provide a wide variety of “security adjustments and upgrades” for his ballroom project. The taxpayer-backed security enhancements would be separate from the $400 million construction cost for the ballroom project that has been funded by private donors, including companies such as Amazon, Apple, Coinbase, Comcast, Google, HP Inc., Lockheed Martin, Meta, Micron Technology, Microsoft, Palantir, Ripple, and T-Mobile.

In a report from Variety today, the spokesperson said that Disney, which took total ownership of Hulu in June 2025, will continue to sell subscriptions to Hulu in the US and that “there are no current plans to sunset the Hulu app.”

Disney owned two-thirds of Hulu before closing its acquisition of the streaming service’s remaining third from Comcast last year. Since then, some reports have suggested that the Hulu app would be phased out in 2026, while others have speculated that Disney would likely, but not definitely, shutter Hulu. Disney’s statement today means that people should be able to continue watching stuff on Hulu without having to pay for Disney+ for the foreseeable future; although, Disney is free to change its mind at any point.

Beyond its potential utility for Colossal's intended efforts, the work is personally interesting to me because it may solve a problem I faced in my research days. I'm going to start by describing the research problem that Colossal may have solved, before coming back to what it hopes to use its technology to do—and why the company still has a few key hurdles left to overcome.

Watching development

For part of my career, I studied the development of vertebrates using chickens. While they're less closely related to us than something like mice, the basics of their development are largely the same. And, unlike mice, they develop outside of their mother's body. If you're careful, you can chip away a hole in the egg, perform manipulations on the developing embryo, and then seal it back up with some tape. The chicken embryo will keep developing, allowing you to see the impact of what you've done on normal development.

While other states imposed restrictions on prediction markets, Minnesota banned them outright in a law signed by Gov. Tim Walz on Monday. The US Commodity Futures Trading Commission announced a lawsuit against the state, saying that Minnesota's "new legislation represents the most aggressive move by a state to shut down CFTC-regulated markets and undermine the federal regulatory regime set up by Congress more than 50 years ago."

“This Minnesota law turns lawful operators and participants in prediction markets into felons overnight,” CFTC Chairman Michael Selig said. “Minnesota farmers have relied on critical hedging products on weather and crop-related events for decades to mitigate their risks. Governor Walz chose to put special interests first and American farmers and innovators last.”
