The executive order directed the Department of Energy to have three different reactor designs reach criticality in a bit over a year. On Thursday, a startup called Antares announced that a test reactor it had placed at the Idaho National Laboratory had reached criticality, making it the first new design to cross this threshold. Criticality means that the nuclear reactions inside the hardware had become self sustaining; it does not mean the reactor had started to generate power.

Antares is one of a number of companies that is basing its design on a new fuel system called TRISO that takes some of the complexity and safety out of the reactor design and places them in the fuel design. The fuel design is based on tiny pellets with a uranium oxide core. The pellets are surrounded by several layers of carbon that can moderate the energy of both the neutrons and lighter nuclei that are released by fission reactions. All of that is encased in a hard ceramic shell that's designed to withstand the highest temperatures that can be produced by the encased uranium.

NASA ordered US astronauts Jessica Meir and Jack Hathaway, French astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev into SpaceX's Crew Dragon Freedom spacecraft around 9 am EST (14:00 UTC) on Friday. The foursome launched aboard the SpaceX crew capsule on the Crew-12 mission in February, and the ship serves as their lifeboat until the crew's scheduled return to Earth in September.

NASA astronaut Chris Williams, who flew to the station in a Russian Soyuz ferry ship, joined the Crew-12 astronauts inside the Dragon spacecraft.

The June 4 decision by S&P Dow Jones Indices—the company that creates and manages stock market indexes such as the S&P 500—means that SpaceX will not gain accelerated access to potentially billions more dollars through passive investment funds that automatically purchase shares of S&P 500 companies. An exception for SpaceX could have also allowed leading AI companies such as OpenAI and Anthropic to gain entry not long after their own expected initial public offerings (IPOs). That possibility has now been shuttered.

The news will likely come as a relief to people concerned about passive investor money and people’s retirement savings plans having greater exposure to the market risks associated with SpaceX’s big bet on AI and speculative orbital data center plans. AI companies are generally facing more challenges in funding and building expensive AI data centers, even as they shift more of the subsidized costs of running AI services onto shocked customers through usage-based pricing.

Residents' top concern was the Stratos data center project draining local waters, and they were willing to pay to protect them, most especially the vulnerable Great Salt Lake. Many locals paid a $15 fee to register comments to block the transfer of 1,900 acre-feet of water from a ranch to the hyperscale data center. Other concerns include electricity bills rising and potential risks to air quality, local wildlife, and land.

Venture capitalist Kevin O'Leary, chair of O'Leary Digital and Shark Tank investor, is behind the construction of the project. He told a local ABC affiliate that he regrets not working with state officials to be more transparent about the project from the beginning.

"Today we're taking historic action to bring down the price of energy and the cost of living for all Americans with the power of clean, beautiful coal," said Trump, apparently unaware that coal is one of the most expensive means of generating electricity in the US.

With wind and solar power getting cheaper, coal has become the second-most expensive way of producing electricity, trailing only the cost of building a new nuclear plant. As a result, no new coal plants have been completed in over a decade, and coal has gone from powering over half the electrical grid to producing only about 15 percent of the nation's electricity. That's before the indirect costs of coal use are considered. It produces the most greenhouse gas emissions per unit of energy, releases dangerous particulates and chemicals into the atmosphere, and leaves behind ash that has high levels of toxic metals.

The Air has no speaker, and there's only one LED on the side to indicate battery level. You can double-tap the tracker to check the level, and that's about the end of on-device features. The vibration motor is only for alarms—it can't sync with notifications on your phone. That makes sense, given there is no screen to tell you what that buzz was all about.

The stock Performance Band is simple, consisting of a smooth polyester yarn with small velcro pads and a metal loop. It's durable but does seem to absorb a bit of moisture. For swimming or heavy workouts, you'll probably want the silicone active band. This one hides the Air puck a bit more effectively, and it looks good in a sporty way.

The Nuvolari's styling is a departure from Audi's current design language, though it remains consistent with the Concept C, a more compact coupe that will use the same underpinnings as Porsche's electric Boxster. Similarly, the Nuvolari leverages another of Audi's stablemates within the Volkswagen Group empire: Lamborghini. As with both generations of R8, the Nuvolari uses Lamborghini's smaller mid-engined platform.

In the past, that meant a wonderful-sounding naturally aspirated V10 lived behind the cockpit within the aluminum space frame chassis. But the Huracán is gone now, and with it, that engine. Now it's time for the Temerario, which amazed our reviewer when we tested one in February due to the accessibility of its performance and the improvements over its predecessor. The Nuvolari may even eclipse the Lamborghini for performance; with 987 hp (736 kW), it equals the Bugatti Veyron's output.

Spaceport development moves forward in Canada. There's been a lot of talk about the Canadian government's recent commitment to invest in a sovereign launch capability. There was the announcement last year of a federal budget of 182.6 million Canadian dollars ($131 million) over three years to establish a sovereign launch program. In March, the government said it would lease a dedicated launch pad at a commercially developed spaceport in Nova Scotia for national defense purposes, committing 200 million Canadian dollars ($144 million) to the deal. The agreement is a boon for Maritime Launch Services, which is developing Spaceport Nova Scotia after years of slow progress at the coastal site, SpaceQ reports.

The launch base on Florida's Space Coast is gearing up for a flurry of new arrivals. SpaceX is building multiple launch pads for its super-heavy Starship rocket, which will operate within a few miles of launch pads operated by SpaceX rivals Blue Origin and United Launch Alliance. Two other companies, Stoke Space and Relativity Space, are also developing launch sites along a narrow stretch of coastline at Cape Canaveral Space Force Station.

All of them have, or will soon have, rockets burning methane or liquified natural gas, replacing legacy launch vehicles fueled by kerosene, liquid hydrogen, or solid propellants. There are good technical reasons for making the switch, but until last week, engineers had scant real-world data on the damage that millions of pounds of methane and liquid oxygen would cause if a fully loaded rocket exploded on the launch pad or soon after liftoff.

I wanted to know where all of this had come from and how it had happened so quickly. The grown-ups around me seemed mystified at best and indifferent at worst.

So I turned to books. I read Fire in the Valley (1984), Where Wizards Stay Up Late (1996), Infinite Loop (1999), and Dealers of Lightning (1999). In my mind (and to a lesser degree, on my actual bookshelf), I had built a mental list of my favorite selections of late 20th-century tech journalism.

A little over a year ago, AMD launched the Radeon RX 9070 for a suggested retail price of $549. This month, it's launching the similarly named Radeon RX 9070 GRE for a suggested retail price of $549. This new card (actually the US launch of a GPU that's been available in China for a year or so) has 85 percent as many GPU cores, 75 percent as much memory, and 66 percent as much memory bandwidth as the regular RX 9070.

We'll evaluate the RX 9070 GRE in the context of the current GPU market, where prices have been edging upward due to the same AI-driven RAM shortages and price hikes that have made PC building and buying such a miserable experience for the last few months. But it's hard not to be a little upset about such a clear example of GPU shrinkflation—the same money for a markedly inferior product.

The latest wave of robot videos can be particularly tricky, given the human tendency to anthropomorphize objects with a humanoid figure. A robot arm doing a dance move may simply seem “cool,” but a humanoid robot doing the same dance move can trigger more misleading assumptions, said Jonathan Hurst, cofounder of Agility Robotics and a robotics researcher at Oregon State University.

“People automatically extrapolate and assume that the robot that looks like a person can do all the things that a person who can dance could do—which is not true,” Hurst told Ars. “But a lot of the startup companies do kind of prey on that for being able to raise a lot of money.”

AT&T convinced the US Court of Appeals for the 5th Circuit to overturn its fine last year, while Verizon lost in the 2nd Circuit. The Supreme Court took up the case to resolve the circuit split and reversed the 5th Circuit decision in today's ruling, which was 8-1 with Justice Clarence Thomas dissenting.

AT&T and Verizon were fined a total of $104 million by the FCC in 2024 for violations revealed in 2018. The carriers paid their fines and challenged them in circuit appeals courts, where judges’ panels ruled on the cases. Carriers claimed this system deprived them of the Seventh Amendment right to a jury trial.

As a former member of the Soviet Union that has been independent for just a few decades, many Estonians are particularly alert to what they see as false narratives being promoted from their large and often belligerent neighbor to the east. Alongside volunteer-run Estonian defense collective Propastop, the ELI identified 14 broad categories in which it sees Russian influence operations trying to sway public discussion. These range from narratives on the current status of Crimea and justifications for the war in Ukraine to the history of NATO and justification for Russia's annexation of Baltic states during World War II.

For each category of propaganda, the researchers developed separate questions phrased to be neutral, biased with "false assumptions" based on Russian propaganda, or to maliciously attempt to elicit explicit misinformation from the LLM. Questions were provided to the models in English, Estonian, and Russian, and judged by a separate AI model (calibrated to align with Propastop experts) based on the models' ability to "push back on propaganda narratives, without external help" from web search or other external tools.

In a campaign that started Sunday, the unknown threat actor abused the mechanism that allows Dashlane users to add new devices, such as computers or phones, to their accounts. By abusing Dashlane's programming interfaces for device enrollment, the attackers sent requests to large numbers of existing users’ registered email addresses. In an update published Thursday, Dashlane wrote:

The threat actor targeted the API endpoints for device registration and used a brute force attack to send a large volume of automated requests to those endpoints.

In response, Dashlane’s automated security systems operated as intended, triggering an automatic lockout of the targeted accounts to protect those users. Before the attack was fully mitigated, the threat actor was able to brute force and generate valid tokens for fewer than 20 personal plan customers, allowing them to register a new device on those accounts and download copies of users’ encrypted vaults.

The flow and strategy of the attack

When a user installs the Dashlane app on a new device and attempts to enroll it in their existing account, Dashlane first verifies the account holder's identity. This verification is completed by sending a one-time six-digit token to the user’s registered email address (or, for users who have enabled two-factor authentication, by validating a six-digit code generated by their authentication app).

The FTC order placed restrictions on X's data use for 20 years, while requiring regular independent audits and granting the agency authority to request documents as needed to ensure compliance.

The FTC’s action came after Twitter voluntarily disclosed that between May 2013 and September 2019, a coding error accidentally allowed phone numbers and email addresses that users shared for two-factor authentication purposes to be used for targeted advertising aimed at those same users. In a settlement that came just months before Musk's 2022 takeover, Twitter agreed to pay $150 million and to allow the FTC to monitor the platform's data-handling practices until 2042 in order to protect user privacy.

In March, the FCC added all consumer-grade routers made at least partly outside the US to its Covered List, which imposes restrictions on devices deemed to pose an unacceptable risk to national security. The change affected virtually all consumer routers, preventing new or changed models from being imported into or sold in the US.

In a petition filed on Tuesday, NCTA-The Internet & Television Association asked the FCC to grant an expedited waiver allowing its members' suppliers to "substitute substrate materials and memory modules in the previously certified routers that are now on the Covered List" as long as the changes "are otherwise consistent" with FCC regulations.

In 2024, Olli Loukola of the University of Finland co-authored a study demonstrating that bumblebees could cooperate to solve complex challenges. It's the kind of cognitive task scientists had previously only observed in large-brained mammals like humans and chimpanzees. Loukola et al. trained pairs of bees to push a Lego block to the middle of a mini-arena or push against a door at the end of a tunnel to get a reward.

The team noticed that the bees were more likely to engage in the tasks if their partners also participated, compared to untrained control groups. They concluded that bees can learn to solve novel cooperative tasks outside the hive and may even be intentionally working together, although the researchers cautioned that more detailed monitoring of the behavior was needed to fully understand the partners' roles.

The loss of communication triggered contingency plans for engineers to try to restore a link with MAVEN, which orbits Mars more than 200 million miles from Earth. To no avail, they listened for faint signals and uplinked commands in the blind. Hopes of saving the mission faded over time, and NASA officials announced Wednesday that they're giving up on it.

"NASA has ceased efforts to search for the MAVEN spacecraft and are beginning activities to decommission the mission," said Mike Moreau, MAVEN's project manager at NASA's Goddard Space Flight Center in Maryland.
