By analyzing a range of federal court and administrative data, the nonprofit Environmental Integrity Project found that civil lawsuits filed by the US Department of Justice in cases referred by the Environmental Protection Agency dropped to just 16 in the first 12 months after Trump’s inauguration on Jan. 20, 2025. That is 76 percent less than in the first year of the Biden administration.

Trump’s first administration filed 86 such cases in its first year, which was in turn a drop from the Obama administration’s 127 four years earlier.

On Thursday, Anthropic researcher Nicholas Carlini published a blog post describing how he set 16 instances of the company's Claude Opus 4.6 AI model loose on a shared codebase with minimal supervision, tasking them with building a C compiler from scratch.

Over two weeks and nearly 2,000 Claude Code sessions costing about $20,000 in API fees, the AI model agents reportedly produced a 100,000-line Rust-based compiler capable of building a bootable Linux 6.9 kernel on x86, ARM, and RISC-V architectures.

As the rumor goes, having a bigger bulge on a required 3D body scan taken in the pre-season could earn jumpers extra centimeters of material in their jumpsuits—and a suit's larger nether regions provide more surface area to glide to the gold. Even a small increase can make a satisfying difference in this sport. A 2025 simulation-based study published in the journal Frontiers in Sports and Active Living suggested that every 2 cm of extra fabric in a ski jumpsuit could increase drag by about 4 percent and increase lift by about 5 percent. On a jump, that extra 2 cm of fabric amounts to an extra 5.8 meters, the simulations found.

Elite ski jumpers are aware of the advantage and have already crotch-rocketed to scandal with related schemes. Last year, two Norwegian Olympic medalists, Marius Lindvik and Johann Andre Forfang, and three of their team officials were charged with cheating after an anonymous video showed the head coach and suit technician illegally restitching the crotch area of the two jumpers' suits to make them larger. The jumpers received a three-month suspension, while the head coach, an assistant coach, and the technician faced a harsher 18-month ban.

In an order on Thursday, district judge Katherine Polk Failla ruled that the extraordinary sanctions were warranted after an attorney, Steven Feldman, kept responding to requests to correct his filings with documents containing fake citations.

One of those filings was "noteworthy," Failla said, "for its conspicuously florid prose." Where some of Feldman's filings contained grammatical errors and run-on sentences, this filing seemed glaringly different stylistically.

We don't know exactly what form that "revisiting" will take at the moment. Analysts who spoke to Ars were somewhat divided on how much of its quickly increasing component costs Valve would be willing (or forced) to pass on to consumers.

"We knew the component issue was bad," DFC Intelligence analyst David Cole told Ars. "It has just gotten worse. "

But then something strange started happening: methane, the second most important anthropogenic greenhouse gas after carbon dioxide, was surging. Its growth rate hit 16.2 parts per billion that year, the highest since systematic records began in the early 1980s. A new study published in the journal Science looked at the complex chemistry of the troposphere (the lowest region of the atmosphere) and found that the two changes are likely connected.

An atmospheric cleaner

Since the late 1960s, we knew that atmospheric methane doesn’t just vanish. It is actively scrubbed from the sky by the hydroxyl radical, a highly reactive molecule that breaks down methane, turning it into water vapor and carbon dioxide. “The problem is that the lifetime of the hydroxyl radical is very short—its lifespan is less than a second" says Shushi Peng, a professor at Peking University, China, and a co-author of the study. To do its job as an atmospheric methane clearing agent, a hydroxyl radical must be constantly replenished through a series of chemical reactions triggered by sunlight. The key ingredients in these reactions are nitrogen oxides, the very pollutants that were drastically reduced when cars stayed in garages and factories went dark in 2020.

Until recently, the autonomous driving industry relied entirely on training data collected from real cars and real situations. That means rare, potentially dangerous events are not well represented in training data. The Waymo World Model aims to address that by allowing engineers to create simulations with simple prompts and driving inputs.

Google revealed Genie 3 last year, positioning it as a significant upgrade over other world models by virtue of its long-horizon memory. In Google's world model, you can wander away from a given object, and when you look back, the model will still "remember" how that object is supposed to look. In earlier attempts at world models, the simulation would lose that context almost immediately. With Genie 3, the model can remember details for several minutes.

The debate goes back at least 15 years, to the early discussions around the design of the heavy lift rocket. The first stage, of course, would be fully reusable. But what about the upper stage of New Glenn, powered by two large BE-3U engines?

Around the same time, in the early 2010s, SpaceX was also trading the economics of reusing the second stage of its Falcon 9 rocket. Eventually SpaceX founder Elon Musk abandoned his goal of a fully reusable Falcon 9, choosing instead to recover payload fairings and push down manufacturing costs of the upper stage as much as possible. This strategy worked, as SpaceX has lowered its internal launch costs of a Falcon 9, even with a new second stage, to about $15 million. The company is now focused on making the larger Starship rocket fully reusable.

As the replacement for the Huracán, Lamborghini’s bestselling sports car to date, the Temerario has big shoes to fill. At first glance, it might seem like a more subdued affair than its predecessor, but the Huracán debuted in a similar fashion before wilder iterations like the STO and Sterrato were introduced to the lineup.

During a technical briefing late last year, Lamborghini sales chief Frederick Foschini noted that the Temerario’s streamlined look is intentional. The team sought to increase downforce by more than 100 percent compared with the Huracán Evo through the car's core design, rather than relying on big wings, splitters, and other racy aerodynamic bits. Designers were also tasked with creating an all-new car that was distinctive yet instantly recognizable as a Lamborghini. Judging by the number of heads this car turned during my time with it, I’d say the company was successful.

For the original paper, Alessandro Chiolerio, a physicist at the Italian Institute of Technology, collaborated with plant ecologist Monica Gagliano of Southern Cross University and several others conducting field work in the Costa Bocche forest in the Dolomites. They essentially created an EKG for trees, attaching electrodes to three spruce trees (ranging in age from 20 to 70 years) and five tree stumps in the forest.

Those sensors recorded a marked increase in bioelectrical activity during a partial solar eclipse on October 22, 2022. The activity peaked mid-eclipse and faded away in its aftermath. Chiolerio et al. interpreted this spike in activity as a coordinated response among the trees to the darkened conditions brought on by the eclipse. And older trees' electrical activity spiked earlier and more strongly than the younger trees, which Chiolerio et al. felt was suggestive of trees developing response mechanisms—a kind of memory captured in associated gravitational effects. Older trees might even transmit this knowledge to younger trees, the authors suggested, based on the detection of bioelectrical waves traveling between the trees.

It wasn't that long ago that everyone was more bullish on electrification. Even the US had relatively ambitious plans to boost EV adoption into the next decade, including a big commitment to charging infrastructure. Ten new battery factories were announced, and the future looked bright.

Not everyone agreed. Some automakers, having been left behind by the push toward battery EVs and away from simple hybrids that offered little in the way of true decarbonization, lobbied hard to relax fuel efficiency standards. Car dealers, uncomfortable with the prospect of investing in and learning about new technology, did so, too. When the Republican Party won the 2024 election, the revanchists got their wish.

The committee met to "mark up" the NASA Reauthorization Act of 2026, adding more than 40 amendments to the bill before a unanimous vote to refer the legislation to the full House of Representatives. Wednesday's committee vote was just one of several steps needed for the bill to become law. It must pass a vote on the House floor, win approval from the Senate, and then go to the White House for President Donald Trump's signature.

Ars has reported on one of the amendments, which would authorize NASA to take steps toward a "commercial" deep space program using privately owned rockets and spacecraft rather than vehicles owned by the government.

Blue Origin "pauses" New Shepard flights. Blue Origin has "paused" its New Shepard program for the next two years, a move that likely signals a permanent end to the suborbital space tourism initiative, Ars reports. The small rocket and capsule have been flying since April 2015 and have combined to make 38 launches, all but one of which were successful, and 36 landings. In its existence, the New Shepard program flew 98 people to space, however briefly, and launched more than 200 scientific and research payloads into the microgravity environment.

In announcing the series, Time Studios President Ben Bitonti said the project provides "a glimpse at what thoughtful, creative, artist-led use of AI can look like—not replacing craft but expanding what’s possible and allowing storytellers to go places they simply couldn’t before."

Outside critics were decidedly less excited about the effort. The AV Club took the introductory episodes to task for "repetitive camera movements [and] waxen characters" that make for "an ugly look at American history." CNET said that this "AI slop is ruining American history," calling the videos a "hellish broth of machine-driven AI slop and bad human choices." The Guardian lamented that the "once-lauded director of Black Swan and The Wrestler has drowned himself in AI slop," calling the series "embarrassing," "terrible," and "ugly as sin." I could go on.

Whether that supervisory model works in practice remains an open question. Current AI agents still require heavy human intervention to catch errors, and no independent evaluation has confirmed that these multi-agent tools reliably outperform a single developer working alone.

Even so, the companies are going all-in on agents. Anthropic's contribution is Claude Opus 4.6, a new version of its most capable AI model, paired with a feature called "agent teams" in Claude Code. Agent teams let developers spin up multiple AI agents that split a task into independent pieces, coordinate autonomously, and run concurrently.

As part of today's Nintendo Direct Partner Showcase, Hamster announced a new Console Archives line of emulated classics available for download starting today on the Switch 2 and next week on the PlayStation 5 (sorry, Xbox and OG Switch fans). So far that lineup only includes the original PlayStation snowboarding title Cool Boarders for $12 and the NES action platformer Ninja Gaiden II: The Dark Sword of Chaos for $8, but Hamster promises more obscure games, including Doraemon and Sonic Wings Special, will be available in the future.

If the name Hamster Corporation sounds familiar, it's because the company is behind the Arcade Archive series, which has repackaged individual arcade games for purchase and emulated play on modern consoles since 2014. That effort, which celebrated its 500th release in December, even includes some of Nintendo's classic arcade titles, which the Switch-maker never officially released on the original Virtual Console.

GPT-5.3-Codex outperforms GPT-5.2-Codex and GPT-5.2 in SWE-Bench Pro, Terminal-Bench 2.0, and other benchmarks, according to the company's testing.

There are already a few headlines out there saying "Codex built itself," but let's reality-check that, as that's an overstatement. The domains OpenAI described using it for here are similar to the ones you see in some other enterprise software development firms now: managing deployments, debugging, and handling test results and evaluations. There is no claim here that GPT-5.3-Codex built itself.
