Doctorow doesn't actually enjoy talking about AI, but he's constantly being asked to comment on it. "I made the tactical error of being sick of talking about AI," Doctorow told Ars. "So I wrote a book about why I think it's a dumb thing to keep asking people to talk about, and now I have to talk about it." Reverse Centaur is Doctorow's attempt to "sort out the bullshit from the material reality."

In automation theory, per Doctorow, a "centaur" describes a human augmented with a technology, like machine learning, or even just driving a car, or using autocomplete. A reverse centaur "is a machine head on a human body, a person who is serving as a squishy meat appendage for an uncaring machine," Doctorow said in a speech last December. He gave the example of an Amazon delivery driver, surrounded by AI cameras monitoring their driving, who essentially serves as a peripheral to the delivery van.

The company developed the new saucer-shaped reentry pod, called Starfall, under a veil of secrecy. Its purpose is to support the "transport and delivery of goods through space," according to an environmental assessment published by the Federal Aviation Administration last month.

The first demonstration of the Starfall vehicle began at 6:53 am EDT (10:53 UTC) with liftoff aboard a Falcon 9 rocket from Cape Canaveral Space Force Station, Florida. At least one Starfall reentry pod rode to orbit on the Falcon 9, perhaps alongside another undisclosed payload. After circling the planet two times, the Falcon 9's upper stage was expected to release Starfall for atmospheric reentry, targeting a parachute-assisted splashdown in the Pacific Ocean around 800 miles west of California.

General Motors installed approximately 50 robot arms at GM’s Factory Zero plant in Detroit, Michigan, according to reporting by Crain’s Detroit Business. Made by the Japanese robotics company FANUC, the robots are designed to help attach various components to vehicles during the assembly line process. But leaders at United Auto Workers (UAW), the primary US union for autoworkers, reacted with anger to the new robotic presence, given how GM has not yet called back any of the workers affected by supposedly temporary layoffs in March.

More than 1,000 union members are still “laid off indefinitely,” James Cotton, president of UAW Local 22, told The Detroit News. He said that the company could bring some of those members back to work instead of installing the 50 robots.

"NASA’s launch infrastructure is vital to providing the agency, other government agencies, and commercial partners access to space for their most complex and expensive missions," states the report, published by the NASA Office of Inspector General. "Nevertheless, NASA’s launch infrastructure is dated and often does not provide the capacity to meet the growing demands of the agency and its partners."

The report covers NASA's launch facilities at the Kennedy Space Center in Florida and Wallops Flight Facility in Virginia. However, the most noteworthy information in the report concerns the Florida spaceport, where demand from SpaceX's Starship and Blue Origin's New Glenn launch vehicles is expected to stress NASA.

Ophthalmologists discovered it when the man, who was in his 20s, appeared at an eye treatment center in Edinburgh. He told them he had noticed increasing floaters and flashing lights in his right eye over the previous six days. According to a BMJ Case Report, the man said he hadn't had any eye or head injuries before the vision problems began, and that his family didn't have a history of eye disorders that might explain them. Besides having mild near-sightedness and needing glasses, he usually didn't have any problems with his eyes, he said.

When the doctors—Niamh O’Connell ‍‍and Ashraf Khan—took a close look, they were surprised to find that both of his eyes were in terrible shape. In his right eye, he had multiple retinal tears, widespread retinal bruising, and a condition called retinal dialysis—a retinal break at a junction in the front of the eye—that is usually seen after a significant eye injury. In his left eye, he had more widespread bruising and six full-thickness rips in his retina.

"In its push to draw users to its unregulated platform, Polymarket has flooded social media with videos like [George] Makihara’s, which appear genuine at first glance," the article said. "In reality, Polymarket built near-perfect copies of its website, then instructed creators to make simulated trades on those dummy sites and hide that they were being paid by Polymarket."

Makihara, a college student, posted a video in January "that showed him winning $100,000 on a wager that President Trump would publicly say the word 'McDonald's' that month." But trade data showed that no one on Polymarket won such a bet in January, according to the Journal. This was one of 145 bets that Makihara appeared to place on Polymarket between January and May, but all of those bets were fake, the article said.

As Ars reported last week, AMD stripped the protection, known as TSME, from consumer Ryzen processors. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to adversaries performing cold boot attacks and similar intrusions requiring physical access.

Now you see it, now you don't, soon you'll see it again

About a decade ago, AMD added TSME to its high-end CPUs. Over the next few years, AMD added the protection to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips have gotten used to the added security, although some security experts (and plenty of novices, too) note that consumer chips are far less likely to be targeted by physical attacks. Recently and without warning or notice, the lower-end line of AMD chips suddenly dropped the protection, and it did so in a way that was impossible to detect on Windows machines and required a fair amount of technical work when using Linux. AMD last week declined to explain or acknowledge the change.

The Steam Machine will come in two variations: one with 512GB of storage and a more expensive one with 2TB. They'll retail for $1,049 and $1,349, respectively, and you'll be able to bundle a Steam Controller with either for an additional $79. Buying the 2TB model also gets you a pair of exclusive faceplates with red fabric and walnut finishes. Like the Steam Deck, the machine ships with the Linux-based SteamOS.

Both versions of the Steam Machine will run on a custom six-core AMD Zen 4 CPU with a peak clock speed of 4.8GHz. The integrated AMD RDNA3 GPU will feature 28 compute units and 8GB of dedicated DDR6 VRAM soldered to the board. The system will have its own 16GB allotment of DDR5 on the board. This should provide enough oomph (with upscaling tech) to play moderately demanding PC games on your TV.

In a statement, the Harris County Sheriff’s Office confirmed to Ars that Michael Butler said that “he was operating with an automated driving-assistance system engaged at the time of the crash.” Police are currently investigating whether the autopilot feature in any way caused the crash but confirmed that Butler was not intoxicated and is cooperating, partly by helping cops understand how Tesla’s Autopilot feature works.

“Butler failed to drive in a single lane, left the roadway, and struck the residence” at a “high rate of speed,” the sheriff’s office said.

These aren't the first layoffs of the year, either; In February, Lucid let go of 12 percent of its workforce.

In a filing with the Securities and Exchange Commission, Lucid wrote that the layoffs were "designed to advance the Company’s path toward profitability and positive cash flow generation by streamlining its organizational structure, optimizing operating expenses, and aligning production plans with anticipated demand."

The launch was scarcely announced in advance. The only public indication of an impending launch was the release of a warning for pilots and sailors to steer clear of the rocket's flight path. Rocket Lab did not provide a livestream of the launch, as it does for most of its missions. As of Monday morning, officials from Rocket Lab and the Space Force had not acknowledged the launch in any official public statements.

But the US military's catalog of space objects was updated over the weekend to reflect the launch. A new satellite, designated Victus Haze Puma, showed up in the catalog with a launch date of Friday from Rocket Lab's privately run spaceport at Māhia Peninsula in New Zealand. The Space Force cataloged the spacecraft in a polar orbit ranging between 215 miles and 286 miles (347-by-461 km), with an inclination of about 97.5 degrees from the equator.

COLORADO SPRINGS, Colo.—If you drive the 12.4-mile (20 km), 156-corner route up Pikes Peak, abiding by the posted speed limit of 25 mph (40 km/h), it will take you a good 30 minutes to reach the top. That's assuming you resist the urge to stop and gawk at the infinite vistas that surround you along the way.

On Sunday, professional racer JR Hildebrand covered that same distance in just 9.5 minutes, ignoring the scenery all the while. He did it in a 1,250 hp (932 kW) hybrid-powered Corvette ZR1X, a car that you can take home yourself for about $210,000. It set a new production car record for the hybrid on a day when EVs and combustion-powered cars fought for mountain supremacy.

2026 marked the 104th running of the Pikes Peak International Hillclimb, one of the most historic races on the planet. Since its inception, competitors have struggled not only to string together all those corners but to maintain speed all the way to the 14,115-foot (4,302 m) summit.

Five in every 1,000 words used by Anthropic in 2026 related to risk, regulation, or restrictions, according to FT research that analyzed official statements, social media posts, and articles written by the company or its chief, Dario Amodei. The equivalent figure for OpenAI and Sam Altman was eight times lower, at 0.6 words per 1,000.

The comparison has become politically charged after Washington last week barred foreign nationals from using Anthropic’s latest models, Mythos and Fable. Some technologists have blamed the decision on the $965 billion AI group’s repeated warnings about AI’s risk to society—particularly in relation to Mythos.

The coal-fired plant had been part of a multibillion-dollar settlement in 2011 after its operator, the Tennessee Valley Authority, failed to install pollution control technology a decade earlier. Regulators cited the plant for more air-pollution violations in 2017 and 2023. TVA said it would shutter Cumberland’s units in 2026 and 2028.

Then the Trump administration replaced four of TVA’s board members, and the agency reneged on its retirement plan in February. Now, TVA has a federal pledge for $46 million to extend Cumberland’s lifespan—part of a nationwide push by President Donald Trump to keep older coal plants running.

Tom Loftis (Matthew Rhys) is a widower and mayor of Widow's Bay, a quirky little seaside town that has a colorfully bizarre history marked by periodic tragedies. Tom is eager to elevate the town into a trendy summer tourist destination. But the arrival of New York Times travel writer Arthur Lloyd (Bashir Salahuddin), who has the clout to make Tom's aspirations for Widow's Bay come true, coincides with the onset of a mysterious fog. Local resident Wyck (Stephen Root) warns Tom that the fog is an omen that the island is "waking up," meaning more supernatural occurrences are bound to happen.

Starting next year, the British government is planning to introduce facial age estimation—where AI scans your face and suggests how old you are—to help determine the age of asylum seekers arriving at the United Kingdom’s border. The move is believed to be the first time that a so-called facial age estimation (FAE) system has been used in this way. Many asylum seekers arriving in the UK will not have documents proving their age, and if children are incorrectly classed as adults, they can be stripped of some legal protections and placed in adult-only detention centers.

An investigation by WIRED and Lighthouse Reports, in collaboration with The Independent, has obtained an internal UK government report detailing its tests of FAE technologies. It shows how the systems regularly mistake children for adults and appear to contain serious bias problems, which directly impact the largest group of migrants subject to age assessments in 2025, according to data from the Home Office. The investigation raises questions about the effectiveness of the technology and whether it should be deployed in such high-stakes scenarios.

Isar test flight scrubbed again. Isar Aerospace still commands top position among a new generation of European rocket startups, but the company’s efforts to launch a critical test flight of its Spectrum rocket continue to encounter roadblocks, Ars reports. The latest delay came Monday, when Isar scrubbed a launch attempt after "detecting off nominal behavior in the vehicle’s fluid systems," according to a social media post. "The teams are analyzing the new data to isolate the root cause." Isar is flush with cash, having raised nearly $1 billion to date, but is still lacking in the critical currency of flight experience. The Spectrum rocket has flown just once to date, on a failed launch last year that lasted less than 30 seconds.

The unmanned surface vehicle, called Yellowfin, was quickly becoming one of the coral researcher’s most dependable guides in these Central Pacific waters.

“She’s the best dive buddy,” said Cohen, a tenured scientist at the Woods Hole Oceanographic Institution in Cape Cod. Programmed to navigate to a precise set of coordinates, the robot cut through small swells like a tiny sailboat without a mast, directing Cohen toward a destination she had traveled thousands of miles to revisit.

Katalyst Space Technologies, a startup founded in 2020, presented the most compelling solution. "They came back with a response that was technically and programmatically plausible, and then we were like, 'Yeah, let’s do it,'" said Shawn Domagal-Goldman, director of NASA's astrophysics division.

That was in August of last year. In September, NASA awarded Katalyst a $30 million contract to build, test, and launch a small satellite to chase down Swift and latch onto it with three robotic arms. Then, Katalyst's Link servicing spacecraft will boost Swift's orbit back to a safe operating altitude, allowing it to resume scientific observations. Easier said than done.
