The original Solterra was a rather underwhelming effort. It looked OK, and it was recognizable as a Subaru from the outside, even if the interior was pure Toyota. But it was inefficient and slow to charge, and in 2024, it was a tough value proposition compared to something like a Hyundai Ioniq 5. For Solterra version 1.1, there's a new visage—does it remind anyone else of an Autobot?—and the tech specs look much improved. At 74.7 kWh, the battery capacity has increased by less than 2 kWh, but its EPA range estimate leaps from 227 miles (365 km) to 288 miles (463 km).

The range increase didn't require something like a decrease in power—in fact, the standard Solterra got a few extra horsepower, taking it to 233 hp (174 kW) from a pair of identical front and rear motors. But alongside the standard powertrain, Subaru now offers the Solterra XT. It almost doubles power to the front motor—it now makes 223 hp (167 kW) to go with the rear's 117 hp (87 kW), for a combined 338 hp (252 kW). There's a small range toll to pay, with an EPA estimate of 278 miles (447 km) for the XT. There's also a slightly larger price tag: The base Solterra starts at $38,495, but the cheapest Solterra XT costs $42,895.

It isn’t the only tech company trying to assess how water scarcity might impact its business. Water use is emerging as one of the most contentious data center issues. A recent Gallup poll found that seven out of 10 Americans are opposed to data center development, with water scarcity ranking as the top resource concern. Facing increasingly fierce resistance, some tech companies are scrambling to assure the public that they’re facing the issue head-on.

Data centers primarily use water to cool server racks, which throw off massive amounts of heat. One popular technique, known as evaporative cooling, uses fresh water to absorb the heat, which is then pumped to cooling towers where it evaporates outside.

The text included a photo of a letter from Columbia, informing me that I was a victim of a data breach last June, one that exposed a wide range of sensitive information, including 1.8 million Social Security numbers.

Columbia's public notices about the breach were addressed exclusively to "members of the Columbia community." In the notices, Columbia warned that an "unauthorized party obtained information about students and applicants related to admissions, enrollment, and financial aid processes, as well as certain personal information associated with some Columbia employees." Major news reports that followed only referenced people affiliated with Columbia as victims, while pointing out that the hacktivist behind the breach was reportedly motivated to expose Columbia's history of "affirmative action-based" admissions.

That prospect comes from a “strategic supply agreement” announced by Waymo and B2U Storage Solutions on June 4. B2U has been repurposing thousands of used batteries from various electric vehicles by installing them in large stationary energy storage projects. Such energy storage facilities can capture excess renewable energy during low demand periods and release such energy when local power grids are experiencing peak demand periods.

“Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use,” Freeman Hall, CEO of B2U Storage Solution, told Ars. “Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them.”

In a social media post on Wednesday afternoon, the USDA revealed that a sample from Texas had been sent to the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, for confirmatory testing of a screwworm infection. Agriculture Secretary Brooke Rollins later posted that the testing had confirmed the infection, which was found in a 3-week-old calf in Zavala County, Texas.

Chatter of a screwworm detection had already been building this week, rattling the US cattle industry.

The past few weeks have seen a number of companies release progress reports on how they're trying to get the technologies closer to general use. None of these represents a major breakthrough, but all are absolutely necessary for the technology to advance. The idea here is to convey the hard work required to move us closer to something useful.

Microsoft does material science

Microsoft is one of the few companies working on topological qubits, based on the distinct physics that occurs when particles are confined. Microsoft's system relies on a thin superconducting wire placed on top of a semiconductor. In superconductors, groups of two electrons form Cooper pairs. But if the wire contains an odd number of conducting electrons—meaning there's a single unpaired electron—it will end up delocalized to both ends of the wire. (Because quantum mechanics is weird.)

"In a world first, publishers will now have effective tools to prevent their content being used to power AI features in search, such as AI Overviews," the CMA said today. "This will put publishers, like news organizations, in a stronger position to negotiate content deals with Google. To boost consumer trust, Google is also now required to make sure that publisher content is properly attributed, using clear links, in AI‑generated search results."

The CMA ruled that Google may not penalize publishers for opting out of AI, meaning that Google can't downrank opted-out publishers in general search results. The CMA said Google will have nine months to comply with all requirements but that the agency "expects important parts of the controls to become available to publishers well before that deadline. Google will also be required to submit and publish compliance reports, supported by key data and metrics, explaining changes it has made and how it has complied."

In April, Google released four models in the Gemma 4 family, which also marked the shift to a more open Apache 2.0 license. The initial models included two mobile-optimized options (E2B and E4B) along with a pair of models for more serious work (26B Mixture of Experts and 31B Dense). That left a rather large unserved space in the middle, which is right where the new model falls.

Gemma 4 12B is considerably more capable than the mobile versions, but it won't require a $20,000 AI accelerator to run locally. Google says Gemma 4 12B is unique in that it can run on many consumer laptops without sacrificing quality. As long as you've got a computer with 16GB of system RAM or VRAM, the 12-billion-parameter model will work. That's about half the total memory footprint of Gemma 4 26B MoE, and Google claims the new model is almost as capable, at least as far as benchmarks go.

Last month, Trump abruptly canceled a signing event, where he had hoped to launch an earlier version of the EO with CEOs of leading AI firms in attendance. Invited at the last minute, several CEOs simply couldn't make the signing but still signaled support for the order. Officially, Trump claimed he postponed the event because he worried that the EO might have gone too far and had become a "blocker" impeding AI innovation. Reports indicated there was infighting in his administration as cybersecurity experts clashed with officials committed to deregulating AI.

The watered-down EO that Trump signed promises not "to stifle this innovation with overly burdensome regulation" and establishes no requirements for AI firms. Instead, it sets up a voluntary process for companies to collaborate with the government on safety reviews that Trump's EO claimed would "ensure that the best and most secure technology is deployed rapidly to confront any and all threats to our country."

As of today, users can make and share "personalized lists on Plex of any movie, show or episode," the company said in an announcement. Later this year, users will be able to import lists from other streaming services and react to other people's lists.

This month, Plex will also launch a community forum that will allow people to "post and comment directly on any movie, show, season, or episode." Later this year, Plex will introduce "Match Scores" based on a viewer's history and past ratings to predict how much they'll like a show or movie, Plex said.

Proponents of the technology, which has attracted at least $100 billion in investment, say robotaxis will be safer than human-driven vehicles. And last year, Waymo's data showed its cars were involved in many fewer crashes than human drivers, with much lower insurance claims, although recent issues with school buses and flooded roads show the technology isn't perfect.

But safety isn't the only selling point: Autonomous vehicles are said to cut traffic. But data from Waymo's reports to the California Public Utilities Commission shows that, at least in that regard, robotaxis are no better than ride-hailing services like Lyft and Uber.

By handing responsibility for Meta’s AI revival to a then-28-year-old start-up founder rather than a veteran researcher, Zuckerberg bet that an outsider’s urgency and ambition could succeed where the company’s established AI organization had struggled.

According to interviews with current and former Meta employees, and associates of Wang, the billionaire wunderkind has now begun to eke out results, while navigating criticism over his experience, early research challenges, and the esoteric internal politics of working at a Big Tech behemoth.

“[One] thing we didn’t know is how the plant detects the caterpillar in the first place,” says Adam Steinbrenner, a biologist at the University of Washington. Now, after years of experimenting with common bean plants in the lab and in the agricultural fields of Oaxaca, Mexico, Steinbrenner’s team pinpointed a single immune receptor that orchestrates its anti-caterpillar defense system.

Drooling caterpillars

When an herbivorous insect like a caterpillar feeds on a plant, it introduces its saliva straight into the plant's damaged tissues. This saliva contains biological clues called HAMPs: herbivore-associated molecular patterns. One of the HAMPs molecules is a peptide called inceptin, and there’s an 11-amino acid fragment of inceptin named In11, as well. Both of them turn out to be a fragment of the ATP synthase found in chloroplasts—basically a piece of one of the plant’s own proteins. As the caterpillar ingests the leaf, its gut enzymes chop up the plant's cellular engines and their pieces, including In11, are regurgitated back onto the leaf’s surface, albeit at extremely small concentrations.

Then, all of a sudden, the rocket exploded. "It came out of nowhere, and it was really violent," Muratore said. This fireball resulted in the destruction of the rocket, much of its launch site, and the AMOS-6 satellite already attached to the vehicle.

Nearly a decade later, on May 28, Blue Origin conducted a static fire test of a new rocket, with its larger New Glenn vehicle a few miles down the Florida coast. The company had gotten further into its test, reaching engine ignition, before its rocket also exploded.

According to a new paper published in the journal Royal Society Open Science by University of Exeter scientists, urbanization and the associated growing availability of brightly colored human-made items have had a significant impact on courtship display behavior in Australian male bowerbirds. There are marked differences in the choice of decorations for bowerbirds in urban versus rural environments. This might be because urban birds simply have greater access to the items than their rural counterparts, since birds in both environments show a marked preference for human items.

The University of Exeter researchers monitored the bowers of 61 male great bowerbirds in two sites in Australia's northern Queensland—the rural Dreghorn Cattle Station and the urban Townsville City—during the prime breeding season (September–December 2023). Then they photographed the bower decorations in situ from above in both visible and UV light (bowerbirds can see in the UV range), using an umbrella to create diffuse lighting.

A few of those announcements stood out to us as particularly interesting, either for esoteric technical reasons or because they seem like they may have some utility for those who aren't spending their every waking moment using generative AI tools. (Microsoft's recent efforts to make its flagship operating system faster, more reliable, more useful, and less annoying didn't really come up, but there have been plenty of other announcements on that front lately.)

On the hardware front, we didn't get any updates for existing Surface devices (not counting yesterday's Surface Laptop Ultra announcement), but we did get something new: the Surface RTX Spark Dev Box is "a compact developer PC" built around Nvidia's new RTX Spark chip with up to 128GB of built-in memory.

Project Solara is not something you'll have to worry about killing your apps anytime soon. It's limited to a few pieces of concept hardware and software that are awaiting the magical agents of the future. The vision is for Solara to run on myriad specialized devices with interfaces generated on the spot, and it's all powered by the explosive intelligence of models that Microsoft and others insist will soon exist.

According to Microsoft, Solara is a chip-to-cloud platform intended to free agents from reliance on single interfaces. Much of Microsoft's messaging around AI is speculative and self-serving, but the company rightly points out that new computing form factors have always required specialization, and that process is complex and expensive. The shift to mobile computing, for example, tripped Microsoft up multiple times as it fell behind on app availability, security, and long-term support.

Plaintiff Charles Sigwalt yesterday filed a class action suit that aims to represent all people in the US "who had their facial recognition data collected, retained, and otherwise used by the Familiar Faces feature created and implemented by Defendant." The lawsuit will seek "far" more than $5 million, but the $5 million figure was given in the complaint because US district courts have jurisdiction for civil actions seeking at least that amount.

"Here, there are millions of Americans who have walked by Ring cameras which have activated the Familiar Faces feature... the damages in this action far exceed $5,000,000.00 when calculating the statutory damages that may be owed to each Class member in addition to the actual damages caused by the aggregate loss of value of biometric information," the lawsuit said.

That's because the archeologists suspected that Neanderthals once used rhino teeth as tools. By using the teeth to make stone tools, the researchers demonstrated that Neanderthals probably did the same thing, adding to what we know about the wide range of items in their toolkits.

We need to hit some rhino teeth with rocks for science

Some Neanderthal archaeological sites in Europe and Asia seem to have many more rhinoceros teeth lying around than you’d expect. We know Neanderthals hunted a now-extinct species of rhinoceros in Europe and eastern Asia, but the people who had inhabited these sites looked like they had been collecting rhino teeth for some reason.
