JCB is a UK-based manufacturer of heavy industrial and agricultural equipment—think diggers, loaders, backhoes, tractors, and so on. And as JCB is based in the UK, it doesn't have the luxury of being able to ignore carbon emissions targets; it has to have alternatives to diesel engines. For some products, that means switching to batteries, but the company has also been working with hydrogen. At first, that meant fuel cells, but after developing prototypes, JCB concluded the tech was too expensive and too fragile for life on the farm or the construction site. Instead, in 2020, the company started developing its own hydrogen combustion engine.

The idea of burning hydrogen in an internal combustion engine has been tried before with little success. For example, in 2006, BMW modified a naturally aspirated V12 engine in a 7 Series to run on hydrogen, which it did, but with 60 percent of the power and five times the fuel consumption compared to gasoline. More recently, Toyota's president Akio Toyoda has been among the drivers of an experimental hydrogen-burning Toyota Corolla in some Japanese endurance races. In this case, Toyota started with the GR Corolla's turbocharged three-cylinder engine; the forced induction from the turbocharger made up somewhat for the reduced energy density of hydrogen.

The Commodity Futures Trading Commission (CFTC) announced that it exercised its emergency authority in response to a "market emergency." The CFTC said it acted "to ensure market stability" and "ordered the exchange to continue to operate in accordance with the Commodity Exchange Act’s Core Principles." The Trump administration took the action after a request from Kalshi.

The market emergency alleged by the CFTC is that New York Attorney General Letitia James sued Kalshi on July 31. James' lawsuit seeks a court order to permanently enjoin Kalshi "from operating an unlawful gambling business" in the state. The lawsuit also demands that Kalshi "make full restitution to customers who have engaged in betting" and pay financial penalties.

It’s indeed depressing to imagine piles of book spines waiting to be fed into wood chippers while torn-out pages are cropped, scanned, and trashed. But that’s the cheapest and easiest way to scan books as fast as possible, and AI companies are in a race to advance their models by training on the kind of engaging, high-quality long-form texts that can only be found in books. So book lovers fear it’s likely that the practice is happening on a grander scale than is currently being reported and that some physical copies of books will be lost forever.

What makes this destruction extra painful, though, is that it doesn’t have to be this way.

The Pixel 11 series is clearly the star of the show. You might even call it the highlight—or HiLight. Just as the leaks predicted, Google's most notable hardware innovation for the 2026 Pixel phones is the return of the notification LED (sort of).

The new HiLight feature is available on the Pro phones, so the base model Pixel will remain unilluminated. HiLight consists of a ring of RGB LEDs inside the flash assembly on the back of the phone. It lights up when you're talking to Gemini, so you don't have to look at the screen of your phone to know you've been heard or that the AI is working. Thus, it makes the most sense when the phone is lying face down.

Researchers from the digital defense firm A Security say the bug was discovered in early June using publicly available AI models, and that it took fewer than 20 prompts to uncover the vulnerabilities and create a working attack. Zoom issued a security advisory on Tuesday, including details about fixes the company has already begun rolling out to address the flaws, which affected devices running all operating systems that Zoom supports—Windows, macOS, Linux, iOS, and Android.

“What is interesting for us and what we believe is dangerous is the democratization of these capabilities—the barrier to entry is dropping rapidly,” A Security cofounder Omer Gull told WIRED ahead of the disclosure. “Before it would have taken a team of five people maybe six months with a lot of refining and iteration to find this. Now people can reach the same results with under 20 prompts. And Zoom is an important type of target because people assume trust when using it. They don’t see it as a threat.”

"This is a landmark moment for Formula E and reflects the incredible momentum behind our Championship," said Formula E's CEO Jeff Dodds. "Disney’s unrivaled global reach and storytelling will introduce Formula E to millions of new fans while bringing them closer than ever to the drama, innovation, and excitement of electric racing. As we enter the GEN4 era, this provides an exceptional platform to accelerate our global growth and continue building one of the world’s most exciting sports properties."

As we've previously covered here at Ars, next season was already shaping up to be a massive one for the electric racing series. It debuts the new GEN4 car in December as well. The new car has double the power of the current racer, with a nominal 603 hp (450 kW) from a twin-motor, all-wheel drive powertrain that goes up to 804 hp (600 kW) in Attack Mode. Which means that for much of a lap, a Formula E GEN4 car will generate as much power as a 2027-spec Formula 1 car; the F1 car is also stuck with just 602 hp from its V6 engine when the battery has no charge.

The first animals on Earth emerged about 600 million years ago, and 60 million years later, those simple early animals evolved in wildly different directions, branching out into a diverse menagerie of complicated new forms and conquering new ecological niches. Known as the Cambrian Explosion, this flurry of rapid evolution produced most of the animal phyla and ecosystems we see around us today.

And it may have taken off because some of those early animals evolved a bizarre new ability: pooping. According to a recent study, the first poo pellets helped spread nutrients to deeper parts of the ocean, fueling the evolution of bigger animals in more diverse ecosystems.

The incident came one day after the DEF CON security conference concluded in Las Vegas and was first described on social media accounts that follow publicly available air-to-ground messages, known as ACARS.

According to the “ACARS Drama” account, a message sent by pilots from the plane stated: “NO INFO AS OF NOW WE HAVE A BUNCH OF PAX THAT WERE AT A CYBER CONFERENCE IN LAS THEY WERE ABLE TO JAM OUR WIFI AND BROADCAST THEIR SIGNAL.”

The responses are unsurprising; the medical and health communities have consistently fought against the anti-vaccine, anti-science agendas pushed by Trump and his health secretary, Robert F. Kennedy Jr., who has no background in science, medicine, or public health. The American Academy of Pediatrics—which called the order "not only disheartening but dangerous"—is leading a lawsuit against previous changes to federal childhood vaccine recommendations under Trump and Kennedy. In March, the organization, along with other medical groups, won a temporary injunction reversing most of the changes.

However, less expected among the scorn for Trump's order is the immediate pushback from the pharmaceutical industry.

Defense Minister Radu Miruță posted a Facebook video supposedly showing one of the drones being blown up in the water by explosive ordnance disposal divers of the Romanian army on August 11, as reported by Reuters and other news outlets. The drones were first spotted in the water by a ship working in the vicinity of the Neptun Deep—an offshore gas project under development in the Black Sea that will make Romania the largest gas producer in the European Union.

A Romanian Coast Guard ship that responded with army soldiers aboard found two drifting Gerbera-type drones of Russian design along with other debris. Miruță also disclosed that Romania had reached out to “Ukrainian partners who confirmed that the systems do not belong to them.”

The new Chrome protection is known as device-bound session credentials (DBSCs). The measure stores a unique encryption key in a silicon-resident fortress that’s built into the device running the browser. On Windows machines, this fortress is called a TPM, short for Trusted Platform Module. On macOS and iOS, it’s known as a secure enclave. Other platforms have differing names. Recently released versions of Chrome for Windows and macOS generate a key that’s stored in this fortress.

An antidote to session cookie theft

DBSCs protect against the theft of session cookies, the unique strings of characters that websites store on browsers. Session cookies greatly speed up browsing on sensitive sites that require user authentication. Instead of requiring the exchange of credentials each time a user opens a new site page, the server sets a session cookie that effectively proves the user has already successfully logged in.

First up among the lawsuits is a case brought against Meta by the California attorney general and other state AGs. Meta said in a July court filing that the state AGs' demands for damages would amount to more than $1.4 trillion. A trial in district court is scheduled to start on August 19, with jury selection beginning August 12.

In a 3-0 ruling yesterday, a judges' panel from the US Court of Appeals for the 9th Circuit rejected the Meta and TikTok claims that they have legal immunity to the lawsuits under Section 230 of the Communications Decency Act.

Gemini has wormed its way into virtually every Google product and service, powering email organization in Gmail, document summary in Drive, and much more. Gemini is also core to Google's flagship search experience, with AI Mode and AI Overviews becoming increasingly hard to avoid. The 1 billion-user metric has nothing to do with any of that, though.

These 1 billion users may also be encountering Gemini in all those places, but that's not the MAU metric. Pichai is talking only about people who are opening the Gemini app or visiting the Gemini web interface to enter a prompt or access Gemini Live. If you used Gemini only once in the past month, you are part of this cohort.

Used EVs also hang around on dealer lots a lot less than new ones—the same analysts at Cox found just 38 days' supply of used EVs in June, but 81 days for new EVs. And much of the demand is at the cheaper end of the spectrum, say the analysts at Recurrent. In previous installments of our used EV buyers' guide, we've already looked at the most affordable used EVs, ending last time at $25,000—EVs that may now qualify for a $1,750 rebate if you're in California. Today we're looking at used EVs that cost between $25,000 and $30,000, and according to Autotrader's search, there are more than 9,000 used EVs for sale in that price range.

Broadly, you can split the results into three buckets: Cars where you'll find plenty to choose from; ones where there might be a couple of hundred for sale nationwide; and then the oddities where there might just be a handful to pick from.

The feces-tainted lettuce was sourced from Mexico and sold by Taylor Farms, a mammoth produce provider based in California. Taylor Farms has drawn scrutiny for its ties to the Trump administration and reluctance to provide information amid the outbreak, which has now sickened over 23,000 people across 47 states, killing two and sending over 500 others to the hospital. Taylor Farms reportedly attempted to delay issuing a recall amid the illnesses and, since then, has refused to clearly report how much tainted lettuce it recalled and where all of it had been shipped.

The FDA's Enforcement Report finally provides some answers: Taylor Farms recalled 236,192 cases of lettuce due to potential Cyclospora contamination. Of those, only 5,900—just shy of 2.5 percent—were sold to Yum, the parent company of Taco Bell, Pizza Hut, and KFC. The other 97.5 percent of the lettuce that potentially sickened Americans was distributed elsewhere.

Generally, studies on heat extremes work with some combination of daily minimum, maximum, and mean temperatures. Sometimes they focus on multi-day heatwaves using those metrics, since the discomfort and health impacts increase for longer events. There are different thresholds you can use to define extreme heat in these analyses, either based on past statistics or on the human body’s physiological limits.

A new study led by Weilin Liao and Xuanzong Zhang at Sun Yat-sen University tried breaking down heat extremes to the hourly level instead, which reveals some interesting nuances.

Six months later, a disillusioned Stapleton resigned, claiming she had been demoted during the most recent restructuring as retaliation for helping to spearhead the walkout. The story of how she went from enthusiastic cheerleader to proactive dissident, and the many lessons she learned along the way, are featured in her new book, Don't Be Evil: Bad Bosses, Fake Promises, and My Escape from Big Tech—A Biting Memoir of Twelve Years Inside Google.

Stapleton didn't set out to be a rabble-rouser. When she joined Google out of college in 2007, it was like "getting the golden ticket in Willy Wonka," she told Ars. Awareness of her good fortune offset any initial uneasiness or skepticism, although Stapleton was sufficiently independent-minded not to move into what was then Google's new corporate housing development in Mountain View, California. Stapleton was very good at her job, and she quickly moved up the ranks, playing a key role in shaping the company's public image.

Historically, the president and Senate worked together to ensure that the president's party maintained only a one-vote majority. Normally, the president's party has three FCC members while the minority party has two.

Instead of the typical 3-2 split, the FCC has operated with a 2-1 Republican majority during Trump's second term. On Friday, Trump nominated Republican Danielle Thumann Severs to take one of the empty spots. Thumann Severs, a lawyer, has been working as FCC Chairman Brendan Carr's senior counsel. She must be confirmed by the Republican-controlled Senate before being sworn in as a commissioner.

After enough trips, software may treat some of those devices as a recurring electronic signature associated with the vehicle. Weeks later, one of the same device signals appears alongside a different car connected to an investigation. The signal itself may not contain its owner’s name, but its previous association with a known vehicle gives investigators another clue they can use to work out who was carrying the device.

SignalTrace, a system marketed by the security company Leonardo, is designed to work alongside automatic license plate readers. The company says it can recognize groups of consumer devices that regularly move together, then associate them with license plate records and time-stamped locations. The pattern can then be searched even when a police investigator does not know the plate number.

The attack is called Pass-ta-key—a blending of the word passkey with the phrase “pass the key” and a nod to a plate of pasta. Arie Olshtein, a researcher at security firm Palo Alto Networks, described in a post last week how Pass-ta-key could obtain all passkeys stored in the Google Password Manager app (GPM) for Windows when it’s running on a machine infected with malware.

This came as a surprise to many people because they believed passkeys are stored exclusively in the trusted platform manager (TPM), the locked-down enclave in a hardened silicon chip that’s reserved for storing cryptographic keys and other highly sensitive information on Windows machines. If passkeys are stored in the TPM, then how was Pass-ta-key able to extract the entire set of passkeys stored by the app, they wanted to know.
