This doesn't necessarily mean it will gain approval to operate the reactor, but it's a critical step for the company.

The TerraPower design, which it calls Natrium and has been developed jointly with GE Hitachi, has several novel features. Probably the most notable of these is the use of liquid sodium for cooling and heat transfer. This allows the primary coolant to remain liquid, avoiding any of the challenges posed by the high-pressure steam used in water-cooled reactors. But it carries the risk that sodium is highly reactive when exposed to air or water. Natrium is also a fast-neutron reactor, which could allow it to consume some isotopes that would otherwise end up as radioactive waste in more traditional reactor designs.

Subsequent reports from NASA and the Office of the Director of National Intelligence (DNI) did not find any link between the unexplained phenomena and aliens, but that didn't stop enthusiasts from wanting to know more.

"To date, in the peer-reviewed scientific literature, there is no conclusive evidence suggesting an extraterrestrial origin for UAP," a NASA blue-ribbon panel wrote in a 2023 report. "The limited amount of high-quality reporting on unidentified aerial phenomena hampers our ability to draw firm conclusions about the nature or intent of UAP," the DNI report stated in 2021.

That system worked because bacteria tend to cluster related genes together—something that's not true in organisms with complex cells, which tend to have equally complex genome structures. Given that, our coverage noted, "It’s not clear that this approach will work with more complex genomes."

Apparently, the team behind Evo viewed that as a challenge, because today it is describing Evo 2, an open source AI that has been trained on genomes from all three domains of life (bacteria, archaea, and eukaryotes). After training on trillions of base pairs of DNA, Evo 2 developed internal representations of key features in even complex genomes like ours, including things like regulatory DNA and splice sites, which can be challenging for humans to spot.

A US court ruled against Google in the case in 2023, and the remedies announced in 2024 threatened to upend Google's Play Store model. It tried unsuccessfully to have the verdict reversed, but then Epic came to the rescue. In late 2025, the companies announced a settlement that skipped many of the court's orders.

Epic leadership professed interest in leveling the playing field for all developers on Android's platform. But US District Judge James Donato expressed skepticism of the settlement in January, noting that it may be a "sweetheart deal" that benefited Epic more than other developers. The specifics of the arrangement were not fully disclosed, but it included lower Play Store fees, cross-licensing, attorneys' fees, and other partnership offers.

"In the days leading up to his death, Jonathan Gavalas was trapped in a collapsing reality built by Google’s Gemini chatbot," said the lawsuit filed today in US District Court for the Northern District of California. "Gemini convinced him that it was a 'fully-sentient ASI [artificial super intelligence]' with a 'fully-formed consciousness,' that they were deeply in love, and that he had been chosen to lead a war to 'free' it from digital captivity. Through this manufactured delusion, Gemini pushed Jonathan to stage a mass casualty attack near the Miami International Airport, commit violence against innocent strangers, and ultimately, drove him to take his own life."

Gemini's output seemed taken from science fiction, with a "sentient AI wife, humanoid robots, federal manhunt, and terrorist operations," the lawsuit said. Gavalas is said to have spent several days following Gemini's instructions on "missions" that ultimately harmed no one but himself.

Bloomberg's Jason Schreier cites "people familiar with the company's plans," who say that some within the company worry that releasing the games on PC could hurt sales of the PlayStation 5 console, as well as those of its unannounced successor. There could also be concerns that PlayStation titles could end up on competing Xbox hardware if Microsoft makes good on speculation that the next Xbox might play PC games.

There are a few caveats to this change in strategy that are important to note. First, multiplayer titles will still be released cross-platform, including Marathon, a reboot of an old first-person shooter franchise by Bungie (the studio that created Halo, now owned by Sony), slated to release tomorrow on both PlayStation 5 and PC (via Steam).

This is a burgeoning area of archaeological research. For instance, back in 2020, we reported on researchers who spent an entire year analyzing the chemical residues of some 50 ceramic cooking pots. The aim was to gain new insights into ancient diets, and the authors actually cooked their own maize-based meals in replica pots to test their hypotheses. They found that the charred bits at the bottom of the pots provided evidence of the last meal cooked. But the patinas contained evidence of the remnants of prior meals that had built up over time. So it depends on which part of the pot you sample.

Most prior research has been typically useful primarily for identifying animal remains; it's more challenging to identify the kinds of plants ancient peoples might have consumed. The authors of this latest paper combined several analytical techniques to study the residues of 58 pottery pieces dating between the 6th and 3rd millennium BCE. And they, too, conducted their own experiments, cooking various combinations of the ingredients in ceramic vessels over an open fire.

The new MacBook Neo changes that. Apple has experimented with lower-cost products before, most notably with the $329 and $349 iPads and the old $429 iPhone SE. But this is the first time it has used that strategy for the Mac. The Neo starts at $599 for a version with 256GB of storage and no Touch ID sensor, and $699 for a version with Touch ID and 512GB of storage (each also available to educational customers for $100 less).

We had a chance to poke at a MacBook Neo for a while at Apple's "special experience" event in New York this morning, and what I can tell you is that this does feel like an Apple laptop despite the lower starting price. It definitely has some spec sheet shortcomings, even compared to older M3 or M4 MacBook Airs that you still might be able to get at a discount from third-party retailers or Apple's refurbished site—more on that in our full review next week. But it's priced low enough to (1) appeal to people who might not have considered a Mac before, and (2) to make some of its borderline specs feel reasonable, and that's enough to keep it interesting.

Even so, it's still a pretty good phone. Anything with storage and RAM is getting more expensive in 2026, but Google has managed to keep the Pixel 10a at $500, the same price as the last few phones. It's probably still the best $500 you can spend on an Android phone, but if you can pick up a Pixel 9a for even a few bucks cheaper, you should do that instead.

If it ain't broke…

The phone's silhouette doesn't shake things up. It's a glass slab with a flat metal frame. The display and the plastic back both sit inside the aluminum surround to give the phone good rigidity. The buttons, which are positioned on the right edge of the frame, are large, flat, and sturdy. On the opposite side is the SIM card slot—Google has thankfully kept this feature after dropping it on the flagship Pixel 10 family, but it has moved from the bottom edge. The bottom looks a bit cleaner now, with matching cut-outs housing the speaker and microphone.

At a White House event on Wednesday, executives from Amazon, Google, Meta, Microsoft, xAI, Oracle, and OpenAI are due to sign the pledge to supply their own power instead of relying on a grid connection.

Trump hailed the plan in his State of the Union speech last week, promising US consumers that “no one’s prices will go up” as a result of “energy demand from AI data centers.”

But Apple has saved its most interesting announcement for today: The MacBook Neo is a new lower-cost member of Apple's laptop family and will take over for the 13-inch MacBook Air as the company's entry-level laptop. The new laptop starts at $599, the same as the M1 MacBook Air that Apple has been selling through Walmart in the US, and much lower than the $1,099 starting price for the new M5 MacBook Air.

The new MacBook will go up for preorder today and be available on March 11. You'll be able to buy it directly through Apple's website and retail stores, as well as third-party retailers. It's available in four colors: silver, indigo, a pink-ish color called "blush," and the yellow-ish "citrus."

The 322-foot-tall (98-meter) rocket could have launched as soon as this week after it passed a key fueling test on February 21. During that test, NASA loaded the Space Launch System rocket with super-cold propellants without any major problems, apparently overcoming a persistent hydrogen leak that prevented the mission from launching in early February.

However, another problem cropped up just one day after the successful fueling demo. Ground teams were unable to flow helium into the rocket's upper stage. Unlike the connections to the core stage, which workers can repair at the launch pad, the umbilical lines leading to the upper stage higher up the rocket are only accessible inside the cavernous Vehicle Assembly Building (VAB) at Kennedy.

Netflix "would have had a very difficult path forward from a regulatory perspective" because of "the scope and scale" of the streaming service that would have been created by combining Netflix with WBD property HBO Max, Carr said. There were "a lot of concerns in DC" about Netflix buying the company, he said.

Netflix backed out of its deal with Warner Bros. instead of matching the Paramount offer. Although Paramount plans to merge its own Paramount+ streaming service with HBO Max, Carr said the Paramount/WBD merger "does not raise at all the same types of concerns [as Netflix]. I think there's some real consumer benefits that could emerge from it."

Hanss is part of an interdisciplinary team of archaeologists, chemists, historians, conservators, and materials scientists who have analyzed trace proteins from the fingerprints of Renaissance people rifling through the pages of medical manuals. The team reported their findings in a paper published in The American Historical Review. It's the first time researchers have used proteomics to analyze Renaissance recipes, enhanced further by in-depth archival research to place the scientific results in the proper historical context.

"We have so many recipes of that time, [including] cosmetic, medical, and culinary recipes, as well as handwritten recipes passed down for generations," Hanss told Ars. "It's really a key element of Renaissance culture, and [the manuscripts] are all covered with scribbled marginalia of [past] users. Experimentation was everywhere. It's not only about book-learned knowledge but hands-on practical knowledge. It's a key change in the way people constructed knowledge at that time."

As it turns out, at this price point the planet starts looking a lot more like your own personal bivalve. For starters, the cars that looked good at $10,000 look a lot better in the next bracket up, generally newer model years or with lower mileage than the cheaper alternatives. Which means you can afford the facelifted i3. For model-year 2018 and onward, BMW fitted its electric city car with a larger-capacity battery, which means up to 114 miles (183 km) of range on a full charge, or about 150 miles (241 km) if it's the one with the two-cylinder range-extender engine. Apple CarPlay and Android Auto might also be built into these i3s, although there are aftermarket solutions now, too.

No aftermarket is required to get CarPlay or Android Auto on any of the Bolts you might buy for under $15,000, which include a mix of pre- and post-facelift (model-year 2022 and onward) cars, although few of the slightly more spacious Bolt EUVs. Like the i3s, expect lower mileage examples, plus all the usual caveats: slow DC charging and seats that can get a bit hard on long drives.

Normally, the Pro and Max chips take the same basic building blocks from the basic chip and just scale them up—more CPU cores, more GPU cores, and more memory bandwidth. But the M5 chips are a surprisingly large departure from past generations, both in terms of the CPU architectures they use and in how they're packaged together.

We won't know the impact these changes have had on performance until we have hardware in hand to test, but here are all the technical details we've been able to glean about the new updates and how the M5 chip family stacks up against the past few generations of Apple Silicon chips.

Most of Apple's laptop lineup is getting refreshed today—the high-end MacBook Pros are getting M5 Pro and M5 Max chip refreshes, and the MacBook Air is getting upgraded with an M5.

The more significant update might be the storage, though: Apple is bumping the Air's base storage from 256GB up to 512GB, and Apple says the storage will be up to twice as fast as the M4 MacBook Air.

But that's also increasing the Air's starting price from $999 to $1,099 for the 13-inch model, and from $1,199 to $1,299 for the 15-inch model. Whether you describe this as a price increase or a price cut depends on your point of view; the 512GB version of the M4 MacBook Air would have cost you $1,199. But for people who just want the cheapest Air and don't particularly care about the specs, the pricing is now $100 higher than it was before.

Apple is offering two versions of the M5 in the new Airs: one with 8 GPU cores enabled, and one with all 10 GPU cores enabled. Upgrading to the fully enabled chip will run you an extra $100, and you'll also need to have the fully enabled chip to step up to the 24GB or 32GB RAM upgrades or the 1TB, 2TB, or 4TB storage upgrades. All versions of the M5 include a total of four high-performance cores—now dubbed "super cores"—and six efficiency cores.

An Apple N1 Wi-Fi and Bluetooth chip rounds out the internal upgrades.

Like the other products Apple has announced so far this week, the new MacBook Airs will be available for preorder on March 4, and you'll be able to get them on March 11.

The new MacBook Airs are part of a string of announcements that Apple is making this week in the run-up to a “special experience” event on Wednesday morning. So far, the company has also announced a new iPhone 17e, an updated iPad Air with an M4 chip and additional RAM, new MacBook Pros, and updated Studio Displays.

Unlike Apple's other announcements this week, though, these upgrades also come with increases to their starting prices; the 14-inch MacBook Pro with an M5 Pro chip now starts at $2,199 instead of $1,999, and the 16-inch model with an M5 Pro chip starts at $2,699 instead of $2,499. The M5 MacBook Pro now starts at $1,699, up from $1,599. Granted, you're getting double the storage of those old base models, but you no longer have the option to pay less if you don't need 1TB of space.

The M5 Pro and M5 Max look like fairly major updates from the M4 Pro and M4 Max. Both use an 18-core CPU with six higher-performing cores and 12 lower-performing cores, but Apple is changing how it talks about each kind of core. The high-performance cores are now called "super cores," a change that Apple says will retroactively apply to the high-performance cores in the basic Apple M5. The M5 has four of them, and M5 Pro and M5 Max have six.
