The holdup means that Waymo isn’t yet allowed to expand into parts of Northern and Southern California. And, in an upside for riders, Waymo still isn’t able to charge California passengers for rides in its new vehicle, a pale blue Chinese-made car it’s calling the Ojai, which started picking up riders last month.

If Waymo continues to operate these vehicles in its driverless ride-hail service, they could be gratis until the end of September and perhaps beyond. (The company continues to charge for rides in its Jaguar I-Pace robotaxis, which make up the majority of its fleet.)
Unlike other states that allow robotaxis to launch testing operations and later public service without much, if any, oversight, California doesn’t allow the vehicles to hit the roads without permission. To put their autonomous vehicles on the road, companies require approval from the state Department of Motor Vehicles. They also need permission from the California Public Utilities Commission, which regulates taxi and other transportation services, to carry paying passengers. Credit: Waymo

The inclusion of Relativity Space, which is making credible progress toward the launch of its heavy-lift Terran R rocket, is perhaps not a huge surprise. Under the leadership of former Google chief executive Eric Schmidt, the company has continued to work toward bringing the partly reusable rocket to the launch pad.

The addition of Impulse Space, however, was something of a surprise. The company specializes in building spacecraft for in-space operations, rather than launching from Earth.

With a payload capacity of more than 100 metric tons (220,000 pounds) to low-Earth orbit, SpaceX's new rocket is changing the thinking of just about everyone in the space industry. With the unrealized but potentially game-changing benefits of refueling, Starship could carry the same amount of payload to higher orbits, the Moon, or Mars.

It's important to note that Starship is still very much in its experimental phase, far from proving Elon Musk's loftiest claims about what it can do. Still, NASA and the US military are considering novel ways to use Starship to fly to the Moon or transport cargo to far-flung war zones. Scientists are eager to use its enormous volume to launch giant space telescopes. Competitors are taking notice. China, the strongest strategic adversary America has ever faced, is looking for its own Starship. Now, some US satellite manufacturers are adapting for the substantial capacity of the world's most powerful rocket.

A new scandal at Brown University reveals that huge numbers of these students are likely to cheat.

Record scores

A recent survey of Princeton students found that 29.9 percent admitted to cheating with AI on at least one exam or assignment. But the recent situation at Brown gives us a better sense of what this kind of cheating looks like in one particular class—and just how much it may be substituting for actual learning. And we know all this because the blind economics professor at the center of it all, Roberto Serrano, is not letting it go.

In March, a girl’s stepfather took his own life after cops discovered that he had used Grok to create 7,000 sexually explicit images using one photo taken when his stepdaughter was 11 years old, the amended complaint alleged.

Grok allowed the man to generate extreme images depicting incest and rape without flagging any harmful behavior, the complaint said. Seemingly, xAI’s child safety system only intervened after the man input a prompt for “gang rape.” That request sent a CyberTip to the National Center for Missing and Exploited Children (NCMEC), which alerted law enforcement to the AI CSAM.

Kalshi is appealing the decision to a higher court. This is one of numerous cases in which judges must decide whether state laws are preempted by federal regulation of prediction markets.

New York Governor Kathy Hochul and Attorney General Letitia James issued a joint statement on the ruling today. “New York’s gambling laws are designed to protect consumers," they said. "Kalshi tried to ignore them. Yesterday, they lost in court. We will continue to hold all gambling platforms accountable to the law—and that includes prediction markets.”

The vulnerability resides in KVM, which is, in essence, a virtual machine app included in the kernel of many Linux distributions. The vulnerability, tracked as CVE-2026-53359, allows guest virtual machines—such as those used in cloud platforms to isolate one user’s instance from the host OS and other user instances—to break out of that container.

Januscape: A threat to cloud platforms

The vulnerability affects KVM running on both AMD and Intel processors. It exploits bugs residing in the KVM guest-side, the portion of the VM that consists of only resources like the OS or drivers present in the guest VM, rather than resources present on the host machine. The threat went unnoticed in the Linux kernel for 16 years.

In 2020, as part of a program conducted by the Australian Competition & Consumer Commission (ACCC), the Australian government's chief competition regulator, thousands of volunteers received routers to help test and report on the typical speed and performance of broadband plans in Australia. (More specifically, the Measuring Broadband Australia (MBA) program targeted fixed-line broadband services provided over the NBN, Australia's government-owned wholesale open-access broadband network, as well as services delivered over other access networks.)

According to the final report that the ACCC distributed, the routers are whiteboxes that were “supplied by SamKnows” and that “perform tests to measure internet performance using test servers maintained by SamKnows and hosted in Australia.”

But some users have voiced concerns that TikTok's almighty algorithm doesn't seem to incorporate negative feedback very well. Even when they don't watch a suggested video or click the "not interested" feature, they keep seeing those videos on their FYP. Northwestern University computer scientists put those suspicions to the test. According to their recent paper, the engagement signals do have an effect, but only temporarily. Then the algorithm gradually relapses unless a user consistently gives the same feedback over and over again.

The research group specializes in "algorithm audits," co-author Piotr Sapiezynski told Ars, to better understand online platforms: "how they work, how they fail, when they fail, how they harm individuals and societies." In this case, he and his co-authors wanted to take a closer look at user agency after hearing multiple anecdotal reports from TikTok users that their negative feedback—responding to prompts by indicating they aren't interested or want to see less of a certain kind of video—doesn't seem to remove those posts from their FYP. "On the other hand, it's unclear why the platforms would offer it, if it doesn't work," said Sapiezynski.

In a call for industry pitches, the Defense Innovation Unit’s notice described the US military’s current reliance on drones and crewed aircraft, each costing more than $30 million, as being “unsustainable against adversaries utilizing layered defenses enabled by increasingly low-cost antiaircraft capabilities.” It envisions deploying more “cost-effective” drones to “overwhelm enemy air defenses even while experiencing numerous [drone] losses.”

That is, in practice, what Ukraine’s military has been demonstrating with its long- and mid-range strike campaign against Russian supply lines, oil refineries, and various energy or industrial targets within Russia or occupied Ukraine. The Ukrainian campaign has been overwhelming Russia’s overstretched air defense capabilities by launching hundreds of relatively inexpensive drones and missiles on a daily basis to attack targets far behind the frontlines, while continuing to damage or destroy Russia’s most sophisticated air defense systems.

It's a long way from launching a bona fide nuclear reactor, a breakthrough that could help power a permanent Moon base and efficiently drive rockets throughout the Solar System. But you have to start somewhere.

The satellite from Miami-based City Labs is named BOHR, short for Betavoltaic Orbital High-Reliability, and it launched on a SpaceX rideshare mission Tuesday alongside 80 other payloads. SpaceX's Falcon 9 rocket released the BOHR satellite into an orbit between 350 and 400 miles (nearly 600 km) in altitude.

While they are popular coding tools, LLMs don't get everything right. Separating the useful outputs from straight-up slop means choosing the right tool. Android Bench aims to demonstrate which AI agents do best on a suite of 100 Android development tasks. After launching Android Bench in March, Google has added metrics like cost and efficiency, as well as open-weight models.

To keep Android Bench relevant, Google is updating the test with eight new models, including all the latest heavy-hitters: Claude Fable 5, Claude Sonnet 5, Claude Opus 4.8, GLM 5.2, Kimi K2.7 Code, MiniMax M3, Qwen 3.7 Plus, and Qwen 3.7 Max.

In other words, we have a good idea of the outcome of the process, but not a detailed picture of the process itself.

That is starting to change. In 2024, a team of French scientists was able to remotely monitor a major event on the border between the Australian and Antarctic plates, only two months after they installed equipment on the ocean floor. Their data shows that most of the spreading occurred in a relatively short time window, and some key events happened without any obvious seismic activity.

Rare earths products produced by MP Materials, Energy Fuels and Phoenix Tailings—which together have won billions of dollars in US government support—are being sold to companies in Asia, where the scale of magnet manufacturing remains larger than the nascent production in the US.

China’s lock on global supplies of rare earths and critical minerals has become a national security concern in the US and other Western nations, since Beijing started restricting access to them. The metals are crucial to 21st-century technology and are used in the manufacturing of everything from weapons guidance systems to electric vehicle batteries.

With no way to enforce this crucial boundary between trusted and untrusted sources, AI engine developers are left to erect elaborate guardrails designed to mitigate the damage rather than solve the root cause.

To date, most prompt injections have fallen into a class known as push, in which each potential victim is targeted. For example, the adversary injects malicious instructions into an individual email or calendar invitation. Because the injection must then be sent (or pushed) to each specific target, the scale of the attack is limited, hampering mass exploits that hit the Internet at large.

Factory electricity bills are generally rising faster than those for other business customers or residential customers, according to a Reuters analysis. It highlighted the example of the Belden Brick Company, a 141-year-old brick manufacturer in Ohio, whose electricity bills have soared from $1,600 to $12,000 per month due to a higher monthly capacity charge in the 13-state region served by the grid operator PJM Interconnection.

Meanwhile, the Steel Manufacturers Association warned that US steel companies concentrated in the Rust Belt region served by PJM Interconnection are paying tens of millions of dollars in higher power costs per year. Electricity accounts for 20 to 40 percent of the total production costs of making steel.

The findings suggest far more Americans than previously thought may be at risk of the allergy, which can make having a hamburger for dinner a potentially life-threatening choice. The Centers for Disease Control and Prevention has previously estimated that only 0.14 percent of the US population (up to 450,000 people) has the allergy. But the study also highlights how little we understand about this unique disease—and the challenges of accurately diagnosing it.

The study surveyed blood donations for the disease's key antibody, which is in a class dubbed IgE and specifically attacks a double-sugar molecule called galactose-α-1,3-galactose, also known as alpha-gal. This disaccharide is found decorating the cells of nonprimate mammals, including cows and pigs, but it's also released in the saliva of ticks, particularly the lone star tick (Amblyomma americanum). People bitten by ticks can develop IgE antibodies against alpha-gal, which can sometimes trigger an allergic response to eating red meat as well as other animal products, such as dairy and gelatin.
