Death was everywhere. Animal corpses littered the landscape and were mired in the local waterhole as ash swept around everything in its path. For some, death happened quickly; for others, it was slow and painful.

This was the scene in the aftermath of a supervolcanic eruption in Idaho, approximately 1,600 kilometers (900 miles) away. It was an eruption so powerful that it obliterated the volcano itself, leaving a crater 80 kilometers (50 miles) wide and spewing clouds of ash that the wind carried over long distances, killing almost everything that inhaled it. This was particularly true here, in this location in Nebraska, where animals large and small succumbed to the eruption’s deadly emissions.

Eventually, all traces of this horrific event were buried; life continued, evolved, and changed. That's why, millions of years later in the summer of 1971, Michael Voorhies was able to enjoy another delightful day of exploring.

For many artists, it's a precarious time to post art online. AI image generators keep getting better at cheaply replicating a wider range of unique styles, and basically every popular platform is rushing to update user terms to seize permissions to scrape as much data as possible for AI training.

Defenses against AI training exist—like Glaze, a tool that adds a small amount of imperceptible-to-humans noise to images to stop image generators from copying artists' styles. But they don't provide a permanent solution at a time when tech companies appear determined to chase profits by building ever-more-sophisticated AI models that increasingly threaten to dilute artists' brands and replace them in the market.

In one high-profile example just last month, the estate of Ansel Adams condemned Adobe for selling AI images stealing the famous photographer's style, Smithsonian reported . Adobe quickly responded and removed the AI copycats. But it's not just famous artists who risk being ripped off, and lesser-known artists may struggle to prove AI models are referencing their works. In this largely lawless world , every image uploaded risks contributing to an artist's downfall, potentially watering down demand for their own work each time they promote new pieces online.

Microsoft has been trying to make Windows-on-Arm-processors a thing for so long that, at some point, I think I just started assuming it was never actually going to happen.

The first effort was Windows RT , which managed to run well enough on the piddly Arm hardware available at the time but came with a perplexing new interface and couldn't run any apps designed for regular Intel- and AMD-based Windows PCs. Windows RT failed, partly because a version of Windows that couldn't run Windows apps and didn't use a familiar Windows interface was ignoring two big reasons why people keep using Windows.

Windows-on-Arm came back in the late 2010s, with better performance and a translation layer for 32-bit Intel apps in tow. This version of Windows, confined mostly to oddball Surface hardware and a handful of barely promoted models from the big PC OEMs, has quietly percolated for years. It has improved slowly and gradually, as have the Qualcomm processors that have powered these devices.

Officially, of course, the Atlantic hurricane season begins on June 1, But most years, the tropics remain fairly sleepy for the first month or two, allowing coastal residents to ease into the season.

Yes, a tropical storm might form here or a modest hurricane there. But the really big and powerful hurricanes, which develop from tropical waves in the central Atlantic and roar into the Caribbean Sea, do not spin up until August or September when seas reach their peak temperatures.

Not so this year, in which the Atlantic Ocean is boiling already. The seas in the main development region of the Atlantic have already reached temperatures not normally seen until August or September. This has led to the rapid intensification of Hurricane Beryl, which crashed through the Windward Islands on Monday and is now traversing the Caribbean Sea toward Jamaica.

Two big things happened in the world of text-based disk operating systems in June 1994.

The first is that Microsoft released MS-DOS version 6.22, the last version of its long-running operating system that would be sold to consumers as a standalone product. MS-DOS would continue to evolve for a few years after this, but only as an increasingly invisible loading mechanism for Windows.

The second was that a developer named Jim Hall wrote a post announcing something called “PD-DOS.” Unhappy with Windows 3.x and unexcited by the project we would come to know as Windows 95, Hall wanted to break ground on a new “public domain” version of DOS that could keep the traditional command-line interface alive as most of the world left it behind for more user-friendly but resource-intensive graphical user interfaces.

Most readers probably did not anticipate seeing a Tour de France preview on Ars Technica, but here we are. Cycling is a huge passion of mine and several other staffers, and this year, a ton of intrigue surrounds the race, which has a fantastic route . So we're here to spread Tour fever.

The three-week race starts Saturday, paradoxically in the Italian region of Florence. Usually, there is a dominant rider, or at most two, and a clear sense of who is likely to win the demanding race. But this year, due to rider schedules, a terrible crash in early April, and new contenders, there is more uncertainty than usual. A solid case could be made for at least four riders to win this year's Tour de France.

For people who aren't fans of pro road cycling—which has to be at least 99 percent of the United States—there's a great series on Netflix called Unchained to help get you up to speed. The second season, just released, covers last year's Tour de France and introduces you to most of the protagonists in the forthcoming edition. If this article sparks your interest, I recommend checking it out.

In 2017, Kathleen Odean thought she had found the last cell phone plan she would ever need. T-Mobile was offering a mobile service for people age 55 and over, with an "Un-contract" guarantee that it would never raise prices.

"I thought, wow, I can live out my days with this fixed plan," Odean, a Rhode Island resident who is now 70 years old, told Ars last week. Odean and her husband switched from Verizon to get the T-Mobile deal, which cost $60 a month for two lines.

Despite its Un-contract promise, T-Mobile in May 2024 announced a price hike for customers like Odean who thought they had a lifetime price guarantee on plans such as T-Mobile One, Magenta, and Simple Choice. The $5-per-line price hike will raise her and her husband's monthly bill from $60 to $70, Odean said.

The Star Wars franchise is creeping up on the 50-year mark for the original 1977 film that started it all, and Disney+ has successfully kept things fresh with its line of live-action Star Wars spinoff series. The Mandalorian and Andor were both unquestionably popular and critical successes, while The Book of Boba Fett ultimately proved disappointing, focusing less on our favorite bounty hunter and more on setting up the third season of The Mandalorian . Obi-Wan Kenobi and Ahsoka fell somewhere in between, bolstered by strong performances from its leads but often criticized for sluggish pacing.

It's unclear where the latest addition to the TV franchise, The Acolyte , will ultimately fall, but the first five episodes aired thus far bode well for its place in the growing canon. The series eschews the usual Star Wars space-battle fare for a quieter, space Western detective story—who is killing the great Jedi masters of the galaxy?—with highly choreographed fight scenes that draw heavily from the martial arts. And like its predecessors, The Acolyte is recognizably Star Wars . Yet it also boasts a unique aesthetic style that is very much its own.

(Spoilers below for episodes 1 through 5 of The Acolyte .)

Late last week, both Bloomberg and The Washington Post published stories focused on the ostensibly disastrous impact artificial intelligence is having on the power grid and on efforts to collectively reduce our use of fossil fuels. The high-profile pieces lean heavily on recent projections from Goldman Sachs and the International Energy Agency (IEA) to cast AI's "insatiable" demand for energy as an almost apocalyptic threat to our power infrastructure. The Post piece even cites anonymous "some [people]" in reporting that "some worry whether there will be enough electricity to meet [the power demands] from any source."

Digging into the best available numbers and projections available, though, it's hard to see AI's current and near-future environmental impact in such a dire light. While generative AI models and tools can and will use a significant amount of energy, we shouldn't conflate AI energy usage with the larger and largely pre-existing energy usage of "data centers" as a whole. And just like any technology, whether that AI energy use is worthwhile depends largely on your wider opinion of the value of generative AI in the first place.

Not all data centers

While the headline focus of both Bloomberg and the Washington Post's recent pieces is on artificial intelligence, the actual numbers and projections cited in both pieces overwhelmingly focus on the energy used by Internet "data centers" as a whole. Long before generative AI became the current Silicon Valley buzzword, those data centers were already growing immensely in size and energy usage, powering everything from AWS web servers to online gaming services, Zoom video calls, and cloud storage and retrieval for billions of documents and photos, to name just a few of the more common uses.
