Meta has struck a multi-billion dollar chip deal with AMD that could lead to the Facebook owner taking a 10 percent stake in the group, sending shares in the US chipmaker surging on Tuesday.

The social media giant said it would acquire customized chips with a total capacity of 6 gigawatts from AMD as it races to develop and deploy its AI models.

AMD’s chief executive Lisa Su said that “each gigawatt of compute is worth double-digit billions” under the deal.

Scotch tape has been a household mainstay for nearly a century, but it still holds some scientific surprises. Researchers have discovered that the screeching sound emitted when one rapidly peels Scotch tape —akin to the screech of fingernails on a chalkboard—is the result of shock waves produced by micro-cracks propagating along the tape at supersonic speeds, according to a new paper published in the journal Physical Review E.

It was a 3M engineer named Richard Drew who developed the first transparent sticky tape in 1930. The impetus came from car manufacturing, specifically two-color designs, where the adhesives used were so sticky they often removed the paint when peeled off; the paint then needed to be manually touched up. Drew found a sandpaper adhesive with just the right amount of stickiness and used it to coat a roll of cellophane tape. (Fun fact: Drew also co-invented the snail-style dispenser for the tape with his 3M colleague, John Borden.) The tape was hugely popular during the Great Depression; consumers used it to repair everyday items rather than replace them. That popularity has never waned.

Scotch tape has also generated considerable interest among physicists. Back in 1939, scientists noticed that peeling tape could produce light—specifically, a glowing line where the tape end pulls away from the roll. The phenomenon was first recorded in the 17th century and is known as triboluminescence : the generation of light when a material is crushed, ripped, rubbed, or scratched. Diamonds, for instance, sometimes glow blue or red during the cutting process, while ceramics emit yellow-orange light when being cut by abrasive water jets.

DALLAS—The Space Force officer tasked with overseeing more than $24 billion in research and development spending says the Pentagon is more interested in supporting startups building new space sensors and payloads than adding yet another rocket company to its portfolio.

The statement, made at a space finance conference in Dallas last week, was one of several points Maj. Gen. Stephen Purdy wanted to get across to a room full of investors and commercial space executives.

The other points on Purdy's agenda were that the Space Force is more interested in high-volume production than spending money to develop the latest technologies, and that the military has, at least for now, lost one of its most important tools for supporting and diversifying the space industrial base.

It seems that tech giants eyeing rural zones for data center development have underestimated how attached American farmers have grown to their lands in the decades they've been nurturing them.

Across the country, several farmers have firmly rejected eye-popping offers—sometimes in the tens of millions. These offers dwarf the value of their properties, but farmers have refused to put a price on the lands that they love most.

In a report on Monday, The Guardian highlighted a handful of cases nationwide where farmers' refusals have frustrated plans to build data centers in areas long deemed rural.

Panasonic, once revered for its plasma TVs, is giving up on making its own TV sets. Today, it announced that Chinese company Skyworth will take over manufacturing, marketing, and selling Panasonic-branded TVs.

Skyworth is a Shenzhen-headquartered TV brand. The company claims to be “a top three global provider of the Android TV platform.” In July, research firm Omdia reported that Skyworth was one of the top-five TV brands by sales revenue in Q1 2025; however, Skyworth hasn’t been able to maintain that position regularly.

Panasonic made its announcement at a "launch event,” FlatpanelsHD reported today. During the event, a Panasonic representative reportedly said:

Last week's surprise departure of Phil Spencer from Microsoft led to the promotion of Asha Sharma, who comes to head Microsoft's gaming division after two years as president of the company's CoreAI Product group . Despite that recent history, Sharma says in a new interview that she has "no tolerance for bad AI" in game development.

Speaking with Variety , Sharma noted that "AI has long been part of gaming and will continue to be," before adding that "great stories are created by humans." The interview comes after Sharma promised in an introductory memo: "We will not chase short-term efficiency or flood our ecosystem with soulless AI slop. Games are and always will be art, crafted by humans, and created with the most innovative technology provided by us."

Those statements seem like a clear line in the sand from Sharma against the use of AI tools in Microsoft's first-party game development, at the very least. But what separates "bad AI" and "soulless AI slop" from "innovative technology" that humans can use to create artful games is a matter of some significant debate in the gaming world.

Mazda provided flights from Washington, DC, to San Diego and accommodation so Ars could drive the CX-5. Ars does not accept paid editorial content.

ENCINITAS, Calif.—Its sales may have been buoyed of late by the big CX-90 and CX-70 SUVs, but for Mazda, the CX-5 is still where most of the action is. Unlike the similar-sized, similar-priced CX-50, which was designed just for North America , the all-new CX-5 is a global car, and it's also Mazda's standard-bearer for a range of new technologies. Gone is the basic but effective infotainment system, replaced by an all-new Google-based experience as Mazda starts its journey toward software-defined vehicles. There's even an in-house hybrid on the way, albeit not until next year. And it starts at a competitive $29,990.

The new CX-5 is bigger than the car it replaces, 4.5 inches (114.5 mm) longer and half an inch (13 mm) wider than before, at 184.6 inches (4,689 mm) long, 73.2 inches (1,859 mm) wide, and 66.7 inches (1,694 mm) tall. Much of that extra space is between the axles—the wheelbase is now 110 inches (2,794 mm) long, which translates to more interior space. From the outside, there's a new light signature, and the way the bodywork curves around the front and wraps down the fenders gives me strong Range Rover vibes, even if I could never adequately capture what I'm talking about with a camera. As ever, Mazda's arresting Soul Red Crystal metallic paint (a $595 option) sparkles, even on a day when the sun remained hidden from view.

The last time that Mazda evolved this compact crossover, it did so with a new upmarket interior . Since then, the brand has staked out that space across its model lineup, with cabins that punch well above their price tags. Happily, the company's designers haven't lost much mojo since then, with a restrained approach that looks good across the five different trim levels, each of which is a $2,000 step up from the one that precedes it. But if you're a current CX-5 driver, you'll find much has changed, perhaps not entirely for the better.

The world’s top AI models can be prompted to generate near-verbatim copies of bestselling novels, raising fresh questions about the industry’s claim that its systems do not store copyrighted works.

A series of recent studies has shown that large language models from OpenAI, Google, Meta, Anthropic, and xAI memorize far more of their training data than previously thought.

AI and legal experts told the FT this “memorization” ability could have serious ramifications on AI groups’ battle against dozens of copyright lawsuits around the world, as it undermines their core defense that LLMs “learn” from copyrighted works but do not store copies .

HBO has another critically acclaimed hit with A Knight of the Seven Kingdoms , based on George R.R. Martin’s Tales of Dunk and Egg novellas, and it deserves every bit of the praise heaped upon it. The immensely satisfying first season wrapped with last night's finale, dealing with the tragedy of the penultimate episode and setting the stage for the further adventures of Dunk and Egg. House of the Dragon is a solid series, but Knight of the Seven Kingdoms has reminded staunch GoT fans of everything they loved about the original series in the first place.

(Spoilers below, but no major reveals until after the second gallery. We'll give you a heads up when we get there.)

A Knight of the Seven Kingdoms adapts the first novella in the series, The Hedge Knight, and is set 50 years after the events of House of the Dragon . Dunk (Peter Claffey) is a lowly hedge knight who has just buried his aged mentor, Ser Arlan of Pennytree (Danny Webb). Ser Arlan was perhaps not the kindest of mentors and often stone drunk, but at least he was hung like the proverbial horse—as viewers discovered in a full-frontal moment that instantly went viral. Lacking any good employment options, Dunk decides to enter a local tournament, since he has inherited Ser Arlan's sword, shield, and three horses.
