Nvidia Announces Vera Rubin Space-1 Chip System For Orbital AI Data Centers 147

Nvidia unveiled its Vera Rubin Space-1 system for powering AI workloads in orbital data centers. "Space computing, the final frontier, has arrived," said CEO Jensen Huang. "As we deploy satellite constellations and explore deeper into space, intelligence must live wherever data is generated." CNBC reports: In a press release, the company said that its Vera Rubin Space-1 Module, which includes the IGX Thor and Jetson Orin, will be used on space missions led by multiple companies. The chips are specifically "engineered for size-, weight- and power-constrained environments." Partners include Axiom Space, Starcloud and Planet.

Huang said Nvidia is working with partners on a new computer for orbital data centers, but there are still engineering hurdles to overcome. "In space, there's no convection, there's just radiation," Huang said during his GTC keynote, "and so we have to figure out how to cool these systems out in space, but we've got lots of great engineers working on it."

Hydropower Line From Quebec Could Power a Million NYC Homes (nytimes.com) 108

The Champlain Hudson Power Express, a $6 billion, 339-mile buried transmission line, will soon deliver Canadian hydropower from Hydro-Quebec to New York City. The project could supply up to 20% of the city's electricity and power roughly one million homes throughout the year. "This is far and away the largest project I have ever worked on," said Bob Harrison, who has worked in infrastructure for 40 years and is the head of engineering for the Champlain Hudson Power Express. "We like to say it's the largest project you'll never see." The New York Times reports: The massive power project, expected to provide energy to a million New York City customers a year, travels underground and underwater, from the northern plains at the Canadian border to the filled-in marshlands of coastal Queens, much of it loosely following the Hudson River. Its construction included the underwater installation of more than two million feet of cable imported from Sweden. It also required special boats, loaded with equipment that could shoot water jets deep into the sediment, to create trenches for the cable. Then, when it came to placing cable beneath the landscape, more than 700 land-use easements were needed, plus an additional 1.55 million feet of cable.

The Champlain Hudson Power Express has found a way to plug into the city, but it wasn't easy. The work included 10 new manholes and more than three miles of new underground circuitry, according to Con Edison, the city's primary electricity provider. "It was literally a hand weave under the streets of Queens," said Jennifer Laird-White, the head of external affairs for Transmission Developers. The hydropower travels from Canada via two buried cables that are as round as cantaloupes. Those lines snake for hundreds of miles under a lake, several rivers (including the Hudson for about 90 miles) and through buried trenches alongside train tracks and roads. The cables resurface in Astoria, Queens, where a converter station shapes, filters and refines the raw power into a product that New Yorkers can consume.

In two cavernous rooms that could be mistaken for "Star Wars" sets, the electricity flows through 30 hanging structures encased in what look like metallic, dinosaurlike exoskeletons. Each one weighs about as much as a small humpback whale and contains microprocessors, thousands of valves and fiber wires. "I am still wowed when I walk into that facility," said Mr. Harrison, the engineer. "I mean, it is just mind-boggling."

'Pokemon Go' Players Unknowingly Trained Delivery Robots With 30 Billion Images 57

More than 30 billion images captured by Pokemon Go players have helped train a visual mapping system developed by Niantic. The technology is now being used to guide delivery robots from Coco Robotics through city streets where GPS often struggles. Popular Science reports: This week, Niantic Spatial, part of the team behind Pokemon Go, announced a partnership with Coco Robotics, a company that makes short-distance delivery robots for food and groceries. Soon, those robot couriers will scoot around sidewalks using Niantic's Visual Positioning System (VPS)-- a navigation tool that can reportedly pinpoint location down to a few centimeters just by looking at nearby buildings and landmarks. Niantic trained that VPS model on more than 30 billion images captured by Pokemon Go users, and claims it will help robots operate in areas where GPS falls short. [...]

Instead of helping users navigate the way that GPS does, VPS determines where someone is based on their surroundings. That makes Pokemon Go particularly useful as a data source, because players had to physically travel to specific locations and point their phones at various angles. That mapping effort got a significant boost in 2020, when the app added what it called "Field Research," a feature prompting players to scan real-world statues and landmarks with their cameras in exchange for in-game rewards. A portion of the data also reportedly came from areas known as "Pokemon battle arenas." Whether players knew it or not, those scans were creating 3D models of the real world that would eventually power the Niantic model. More data means better accuracy, and because Niantic was collecting images of the same locations from many different users, it could capture the same spots across varying weather conditions, lighting, angles, and heights. [...]

The idea is that Coco's robots can use VPS and four cameras mounted around the machine to get a far more precise read on their surroundings. In turn, the well-equipped robot will deliver food on time. On a broader level, Niantic says its partnership with Coco Robotics is part of a longer-term effort to build a "living map" of the world that updates as new data becomes available. Once VPS-equipped delivery robots hit the streets, they will collect even more info that can be fed back into the model to bolster its accuracy further. This kind of continuous, real-world data collection is already central to how self-driving vehicle companies like Waymo and Tesla operate, and is a large part of why that technology has improved so significantly in recent years.

Meta Signs $27 Billion AI Infrastructure Deal With Nebius 8

AI infrastructure company Nebius signed a deal to provide up to $27 billion in AI computing capacity to Meta over the next five years, including a guaranteed $12 billion purchase by 2027. Reuters reports: Under the agreement, Meta will also buy an additional $15 billion worth of capacity planned by Nebius over the coming five years if it is not sold to other customers, giving the contract a total value of up to $27 billion, Nebius said. The deal is the latest example of U.S. tech giants' efforts to supplement their own AI data-centre build-outs by locking in scarce GPU and power capacity from "neocloud" providers like Nebius. Nebius CEO Arkady Volozh said the latest Meta deal would help "accelerate the build-out and growth of our core AI cloud business."

Data Centers Overtake Offices In US Construction-Spending Shift (bloomberg.com) 31

An anonymous reader quotes a report from Bloomberg: Spending on data center projects in the U.S. has exploded, surpassing offices for the first time at the end of last year. It's a trend Matt Kunz saw early on when Meta built a computing hub outside Columbus, Ohio. Other tech companies soon swarmed into the area, drawn by its stable economy, university talent pipeline and ample power, water and land, said Kunz, vice president and general manager at Turner Construction Co., the firm that led Meta's build-out. Since Meta broke ground in 2017, it's expanded its data center campus, and Amazon.com Inc., Alphabet Inc.'s Google and Microsoft Corp. made plans to join it nearby.

"When one shows up, almost all the other ones tend to follow," Kunz said. For Turner, a construction giant responsible for supertall office skyscrapers, sports stadiums and cultural venues around the globe, data centers are commanding more of its bandwidth. The company completed $9.4 billion of the projects last year, more than five times its 2020 total. Last month, Turner announced it was chosen as one of the contractors on a $10 billion data center for Meta in Indiana. Tech companies' needs for AI processing facilities have made data centers the latest darling of the real estate industry. The properties are figuring heavily into portfolios of major investors such as Blackstone, Brookfield Asset Management and KKR, on a bet that long-term demand for computing power will continue to grow. At the same time, office development has slowed as cities across the U.S. contend with vacancies that have piled up since the Covid lockdowns.

Construction spending for data centers has climbed steadily in recent years, while outlays for general office projects headed downward, U.S. Census data show. The two crossed paths in December, with roughly $3.57 billion spent on data centers that month, compared with $3.49 billion for offices, according to preliminary estimates. The shift is likely to continue and "may perpetuate itself even further as AI is utilized for automating day-to-day jobs," said Andy Cvengros, co-lead of U.S. data center markets for the brokerage Jones Lang LaSalle Inc. "It's going to directly impact the amount of office space people need."
According to Christopher McFadden, senior vice president at Turner, more than a third of the company's backlog is now tied to data centers.

"We're going to be building these at this scale for years to come," McFadden said. "There's a lot of wind in the sail."

The UK Will Invest Billions to Build a Nuclear Fusion Industry (thetimes.com) 74

The UK's science minister is announcing details of a five-year, £2.5 billion investment in nuclear fusion, reports the Times of London, "including building one of the world's first prototype fusion power plants in Nottinghamshire and developing a UK sector projected to employ 10,000 people by 2030." Despite the potentially transformative impact of fusion, which in theory could provide limitless clean energy and create a £12 trillion global market, no country has managed to use this fledgling technology to generate useable electricity... [T]he UK is backing a spherical tokamak design... investing an initial £1.3 billion into a prototype fusion power plant called Step (Spherical Tokamak for Energy Production) on the site of a decommissioned coal-fired power station at West Burton in Nottinghamshire. Paul Methven, chief executive of the government-owned UK Industrial Fusion Solutions, which is delivering the Step project, said the aim is to get the reactor operating early in the 2040s. "It's quite an aggressive programme," he said. "We need to show that we can achieve genuine 'wall socket' energy — which has not been done before."

On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds...

Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.

Ask Slashdot: What's the Best All-Purpose RISC-V System on a Chip Family? 36

Slashdot reader SysEngineer does embedded/IoT work, but "I want to pick a single system-on-a-chip architecture family and commit to it across multiple product lines — sensor nodes up through edge gateways... I've been on one platform for years and want to know what embedded engineers are actually running in production before I commit!"

And "the family needs to scale — cheap and small at the low end, capable of running Linux on the bigger variants!"

Their requirements?
  • WiFi + BLE required
  • LoRaWAN a nice-to-have.
  • Low power modes that actually work in the field, not just on the datasheet.
  • Full peripheral set — SPI, I2C, UART, ADC, timers, CAN.
  • A toolchain and runtime support, support multi threads...

Slashdot reader Gravis Zero is skeptical all the requirements can be met. "If you want embedded, you get embedded. If you want to run a big OS, you get one that will run a big OS."

But Slashdot reader SysEngineer believes "The obvious architecture candidates are ARM, STM, and RISC-V" — and specifically they want to hear your experiences with the RISC-V choices. "What would you standardize on today if you were starting fresh? And how does real-world toolchain and community support hold up compared to the marketing?"

Uber Co-founder Travis Kalanick's Newest Venture? 'Gainfully Employed Robots' (yahoo.com) 59

Uber co-founder Travis Kalanick launched a new venture that "will focus on creating 'gainfully employed robots' for the food, mining and transport industries," Bloomberg reports.

"I left Uber in 2017 heartbroken," writes Kalanick on the new company's web site. Kalanick resigned under pressure in 2017, and complains he was "torn away from an idea and a movement that I had poured my life into... I bled, but I did not perish. I got back up and fought my way back into the arena, back to my calling. Back to building. Digitizing the Physical World is my life's work... " Kalanick is remaking his real estate company, City Storage Systems, which owns ghost-kitchen operator CloudKitchens, and renaming it Atoms, according to a manifesto posted on the new company's website. [Bloomberg notes that the company's food robotics division "makes a food assembly machine called Bowl Builder, according to its website."] In addition to its work on food, Los Angeles-based Atoms is expanding into robotics technology for mining and automotive transport. Kalanick said on the livestreamed tech talk show TBPN Friday that Atoms has effectively been in stealth for eight years and has "thousands" of employees....

Kalanick wrote on the Atoms website that the company will make "specialized robots with productive jobs that bring abundance to their owners and society at large." That will include "infrastructure for better food," he wrote, as well as "more productive mines to power Earth's industries" in addition to "wheelbase for robots" in transportation. "The industrial thing is probably our main jam," he said on TBPN. "Once you crack movement in the physical world, there are lots of people who want access to that..." Kalanick also said he was the biggest investor in Pronto, a self-driving trucking startup that currently focuses on closed sites like mines.

Should Banksy Remain Anonymous? (reuters.com) 91

He's "the most famous anonymous man in the world," suggests Reuters. But investigating Banksy's artworks in a bombed Ukrainian village (and other clues in the U.K. and Manhattan) have led them to "a hand-written confession by the artist to a long-ago misdemeanor charge of disorderly conduct — a document that revealed, beyond dispute, Banksy's true identity."

But Banksy's long-time lawyer "urged us not to publish this report, saying doing so would violate the artist's privacy, interfere with his art and put him in danger" and "would harm the public, too." Working "anonymously or under a pseudonym serves vital societal interests," he wrote. "It protects freedom of expression by allowing creators to speak truth to power without fear of retaliation, censorship or persecution — particularly when addressing sensitive issues such as politics, religion or social justice."

Reuters took into account Banksy's privacy claims — and the fact that many of his fans wish for him to remain anonymous. Yet we concluded that the public has a deep interest in understanding the identity and career of a figure with his profound and enduring influence on culture, the art industry and international political discourse... As for the risk he might face of retaliation or censorship, Britain's legal and political establishments seem comfortable with Banksy's messages and how he delivers them...

His mastery of disguise began as a way of shaking the police, says former manager [Steve] Lazarides. In an interview, Lazarides said anonymity served a practical purpose in Bristol, where authorities enforced "draconian" policies against graffiti... Eventually, keeping the secret became a burden. By the end of their partnership, Lazarides estimates he spent half or more of his time managing and maintaining the artist's mystique. "I think it became a good gag, and then, if you want my honest, honest opinion, I think it then became a disease," he said.

Lazarides wrote a two-volume book about managing Banksy from the late 1990s to 2008, including a story about Banksy's arrest in 2000 for this defacing of a billboard. Reuters geolocated that building, then found police documents and a court file including the hand-written confession. This investigation spawned a 7,000-word article with everything from a comic strip Banksy drew when he was 11 to his connections with Robert Del Naja of the trip hop band Massive Attack — and a 2017 podcast interview where a music producer apparently revealed Banksy's real first name.

But the article also reveals how protective the art community is of Banksy's secret. Reuters investigated that Banksy auctioned in 2018 for $1.4 million — and then immediately started shredding itself with a device Banksy embedded in its frame: That piece, renamed "Love is in the Bin," sold three years later for about $25 million. Art dealer [Robert] Casterline was at the auction and remembers when the shredder began to beep. He pulled out his phone to take pictures. "Unfortunately, there was one person standing in front of me," blocking the view, he said. It was an eccentric-looking man with a broad neck scarf and thick eyewear. Oddly, the man wasn't watching the painting get shredded. He was looking in the other direction, observing the crowd's reaction. Only later, reviewing what he shot, did Casterline notice that the man's glasses appeared to have a small camera built into the bridge. (Banksy later posted a video of the stunt, including shots of the astonished audience.)
Having seen a photo of the man suspected of being Banksy, Casterline confirmed to Reuters that he was "pretty sure" it was the same man.

But "I don't want to be the guy who exposes Banksy."

America's First Large-Scale Offshore Wind Project Finally Finishes Construction (wbur.org) 71

It's America's first large-scale offshore wind project, reports WBUR — enough clean energy to power 400,000 homes in Massachusetts from 62 offshore wind turbines generating 800 megawatts.

But it took a while... The plant's first construction delay happened back in 2019, they point out — and then "Just three months ago, when the project was 95% complete, the U.S. Interior Department issued a stop-work order." But after successfully challenging that order in court, and "with a stretch of good weather offshore, the developers behind the $4.5 billion project managed to get over the finish line."

The Associated Press notes it was "one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns." Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt. Another one of the five, Revolution Wind, began sending power for the first time to New England's electric grid on Friday and will scale up in the weeks ahead until it is fully operational.
"That project is nearly complete as well," notes WBUR, "and will eventually be capable of powering up to 350,000 homes."

Are U.S. Utilities Trying to Delay Easy-to-Use Solar 'Balcony' Panels? (npr.org) 120

Plug-in (or "balcony") solar panels can also be hung out a window or be set up in a backyard, reports NPR. They channel energy from the sun straight into a home's electrical outlet, generating enough electricity to power a refrigerator or microwave while "displacing electricity that otherwise would come in from the grid..."

But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.]

But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed....

German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.

Meta Delays Rollout of New AI Model After Performance Concerns 27

Meta has delayed the release of its next major AI model after internal tests showed it lagging behind competing systems from Google, OpenAI, and Anthropic. The New York Times reports: The model, code-named Avocado, outperformed Meta's previous A.I. model and did better than Google's Gemini 2.5 model from March, two of the people said. But it has not performed as strongly as Gemini 3.0 from November, they said. As a result, Meta has delayed Avocado's release to at least May from this month, the people said. They added that the leaders of Meta's A.I. division had instead discussed temporarily licensing Gemini to power the company's A.I. products, though no decisions have been reached.

[...] It takes time to improve A.I. models, and Meta can still catch up to rivals, A.I. experts said. But a longer timeline has set in at the company, with Mr. Zuckerberg tempering expectations for Avocado in the past few months. "I expect our first models will be good, but more importantly will show the rapid trajectory we're on," he said on a call with investors in January.
A Meta spokesperson said in a statement: "As we've said publicly, our next model will be good but, more importantly, show the rapid trajectory we're on, and then we'll steadily push the frontier over the course of the year as we continue to release new models. We're excited for people to see what we've been cooking very soon."

Strait of Hormuz Closure Triggers Work From Home, 4-Day Weeks In Asia (fortune.com) 114

Asian governments are implementing emergency measures like four-day workweeks and work-from-home mandates to cope with a fuel shortage triggered by the Iran conflict and the closure of the Strait of Hormuz. "Asia is particularly dependent on oil exports from the Middle East; Japan and South Korea respectively source 90% and 70% of their oil from the region," notes Fortune. From the report: On March 10, Thailand ordered civil servants to take the stairs rather than the elevator, and to work-from-home for the duration of the crisis. It increased the air-conditioning temperature to 27 degrees Celsius, and will tell government employees to wear short-sleeved shirts over suits. (Thailand has about 95 days of energy reserves left, according to Reuters).

Vietnam also called on businesses to let people work-from-home to "reduce the need for travel and transportation." The Philippines is pushing for a four-day work week, and has ordered officials to limit travel "to essential functions only."

South Asia is getting hit hard too. Bangladesh brought forward the Eid-al-fitr holiday, allowing universities to close early in a bid to save fuel. Pakistan also instituted a four-day week for government offices and closed schools. India suspended shipments of liquefied petroleum gas to commercial operators to prioritize supplies for households, leading to worries from hotels and restaurants that they may be forced to close without fuel supplies.
Countries across the region are also considering price caps, subsidies, and tapping strategic oil reserves. On Wednesday, the International Energy Agency "unanimously" agreed to release 400 million barrels of oil and refined products from its reserves.

The Associated Press offers a look at the energy supplies that countries hold and when they tap them.

Reducing Europe's Nuclear Energy Sector Was 'Strategic Mistake', EU Chief Says (reuters.com) 184

An anonymous reader quotes a report from Reuters: Reducing Europe's nuclear energy sector was a "strategic mistake," European Commission chief Ursula von der Leyen said on Tuesday, as governments grapple with an energy crunch from the Iran war. Europe produced around a third of electricity from nuclear power in 1990 but that has fallen to 15%, she told an event in Paris, leaving it reliant on oil and gas imports whose prices have surged in recent days. Being "completely dependent on expensive and volatile imports" of fossil fuels puts Europe at a disadvantage to other regions, von der Leyen said in a speech. "This reduction in the share of nuclear was a choice. I believe that it was a strategic mistake for Europe to turn its back on a reliable, affordable source of low-emissions power." The report notes that the EU does not directly fund nuclear energy projects because all 27 member states have not unanimously supported the technology. However, von der Leyen said the Commission plans to provide a 200-million-euro guarantee from the EU's carbon market to help attract private investment in innovative nuclear technologies.

OpenAI Is Walking Away From Expanding Its Stargate Data Center With Oracle (cnbc.com) 41

OpenAI is reportedly backing away from expanding its AI data center partnership with Oracle because newer generations of Nvidia GPUs may arrive before the facility is even operational. CNBC reports: Artificial intelligence chips are getting upgraded more quickly than data centers can be built, a market reality that exposes a key risk to the AI trade and Oracle's debt-fueled expansion. OpenAI is no longer planning to expand its partnership with Oracle in Abilene, Texas, home to the Stargate data center, because it wants clusters with newer generations of Nvidia graphics processing units, according to a person familiar with the matter.

The current Abilene site is expected to use Nvidia's Blackwell processors, and the power isn't projected to come online for a year. By then, OpenAI is hoping to have expanded access to Nvidia's next-generation chips in bigger clusters elsewhere, said the person, who asked not to be named due to confidentiality.
In a post on X, Oracle called the reports "false and incorrect." However, it only said existing projects are on track and didn't address expansion plans.

CNBC notes: "Oracle secured the site, ordered the hardware, and spent billions of dollars on construction and staff, with the expectation of going bigger."

Startup Wants To Launch a Space Mirror (nytimes.com) 80

A startup called Reflect Orbital wants to launch thousands of mirror-bearing satellites to reflect sunlight onto Earth at night and "power solar farms after sunset, provide lighting for rescue workers and illuminate city streets, among other things," reports the New York Times. From the report: It is an idea seemingly out of a sci-fi movie, but the company, Reflect Orbital of Hawthorne, Calif., could soon receive permission to launch its first prototype satellite with a 60-foot-wide mirror. The company has applied to the Federal Communications Commission, which issues the licenses needed to deploy satellites. If the F.C.C. approves, the test satellite could get a ride into orbit as soon as this summer. The F.C.C.'s public comment period on the application closes on Monday. "We're trying to build something that could replace fossil fuels and really power everything," Ben Nowack, Reflect Orbital's chief executive, said in an interview. The company has raised more than $28 million from investors.

[...] Reflect Orbital's first prototype, which will be roughly the size of a dorm fridge, is almost complete. Once in space, about 400 miles up, the test satellite would unfurl a square mirror nearly 60 feet wide. That would bounce sunlight to illuminate a circular patch about three miles wide on the Earth's surface. Someone looking up would see a dot in the sky about as bright as a full moon. Two more prototypes could follow within a year. By the end of 2028, Reflect Orbital hopes to launch 1,000 larger satellites, and 5,000 of them by 2030. The largest mirrors are planned to be nearly 180 feet wide, reflecting as much light as 100 full moons. The company said its goal was to deploy the full constellation of 50,000 satellites by 2035.

How much does it cost to order sunlight at night? Mr. Nowack said the company would charge about $5,000 an hour for the light of one mirror if a customer signed an annual contract for 1,000 hours or more. Lighting for one-time events and emergencies, which might require numerous satellites and more effort to coordinate, would be more expensive. For solar farms, he envisions splitting revenue from the electricity generated by the additional hours of light.

New SETI Study: Why We Might Have Been Missing Alien Signals (seti.org) 101

After decades of searching for extraterrestrial intelligence, the nonprofit SETI Foundation has an announcement. "A new study by researchers at the SETI Institute suggests stellar 'space weather' could make radio signals from extraterrestrial intelligence harder to detect." Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches. For decades, many SETI experiments have focused on identifying spikes in frequency — signals unlikely to be produced by natural astrophysical processes. But the new research highlights an overlooked complication: even if an extraterrestrial transmitter produces a perfectly narrow signal, it may not remain narrow by the time it leaves its home system... "If a signal gets broadened by its own star's environment, it can slip below our detection thresholds, even if it's there, potentially helping explain some of the radio silence we've seen in technosignature searches," said Dr. Vishal Gajjar, Astronomer at the SETI Institute and lead author of the paper.
The researchers created "a practical framework for estimating how much broadening could occur for different types of stars" — and accounting for space weather — by "using radio transmissions from spacecraft in our own solar system, then extrapolated to other stellar environments."

The study's co-author (a SETI Institute research assistant) suggests this coud lead to better-targetted SETI searches. (M-dwarf stars — about 75% of stars in the Milky Way — actually have the highest likelihood that narrowband signals would get broadened before leaving their system...)

EFF, Ubuntu and Other Distros Discuss How to Respond to Age-Verification Laws (9to5linux.com) 168

System76 isn't the only one criticizing new age-verification laws. The blog 9to5Linux published an "informal" look at other discussions in various Linux communities. Earlier this week, Ubuntu developer Aaron Rainbolt proposed on the Ubuntu mailing list an optional D-Bus interface (org.freedesktop.AgeVerification1) that can be implemented by arbitrary applications as a distro sees fit, but Canonical responded that the company does not yet have a solution to announce for age declaration in Ubuntu. "Canonical is aware of the legislation and is reviewing it internally with legal counsel, but there are currently no concrete plans on how, or even whether, Ubuntu will change in response," said Jon Seager, VP Engineering at Canonical. "The recent mailing list post is an informal conversation among Ubuntu community members, not an announcement. While the discussion contains potentially useful ideas, none have been adopted or committed to by Canonical."

Similar talks are underway in the Fedora and Linux Mint communities about this issue in case the California Digital Age Assurance Act law and similar laws from other states and countries are to be enforced. At the same time, other OS developers, like MidnightBSD, have decided to exclude California from desktop use entirely.

Slashdot contacted Hayley Tsukayama, Director of State Affairs at EFF, who says their organization "has long warned against age-gating the internet. Such mandates strike at the foundation of the free and open internet."

And there's another problem. "Many of these mandates imagine technology that does not currently exist." Such poorly thought-out mandates, in truth, cannot achieve the purported goal of age verification. Often, they are easy to circumvent and many also expose consumers to real data breach risk.

These burdens fall particularly heavily on developers who aren't at large, well-resourced companies, such as those developing open-source software. Not recognizing the diversity of software development when thinking about liability in these proposals effectively limits software choices — and at a time when computational power is being rapidly concentrated in the hands of the few. That harms users' and developers' right to free expression, their digital liberties, privacy, and ability to create and use open platforms...

Rather than creating age gates, a well-crafted privacy law that empowers all of us — young people and adults alike — to control how our data is collected and used would be a crucial step in the right direction.

As US Tariffs Hit EVs, Hyundai Discontinues Its Cheapest IONIQ 6, While Kia Delays EV6 adn EV9 GT (electrek.co) 74

First, Hyundai "is discontinuing its most affordable electric sedan after just three years on the market," reports USA Today. After being introduced in 2022, the Hyundai Ioniq 6 "quickly gained the admiration of automotive critics because of its affordable pricing and capable performance specs." But now, Hyundai "is axing the most affordable versions of the EV, leaving consumers with only one Ioniq 6 option." Hyundai will continue to produce the Ioniq 6 N performance trim, which is the quickest and most powerful iteration of the Ioniq 6. It's also the most expensive. The South Korean automaker is getting rid of lower Ioniq 6 trims due to "disappointing sales and tariff considerations," according to Cars.com. Hyundai sold 10,478 Ioniq 6 models in 2025, dropping 15% from 12,264 units in 2024, a company sales report stated. Hyundai's Ioniq 6 is mainly produced in South Korea, so it faces high import tariffs.
Sales increased for their earlier IONIQ 5 model, reports the EV blog Electrek, "up 14% through the first two months of 2026, with 5,365 units sold... Meanwhile, IONIQ 6 sales slid 77% with only 229 units sold in February."

Elsewhere they report that Kia's EV6 and EV9 "didn't fare much better with sales down 53% (600 units sold) and 40% (819 units sold), respectively." Now a Kia spokesperson tells Car and Driver that the 2025 EV6 GT and 2026 EV9 GT "will be delayed until further notice." They attributed the move to "changing market conditions," but added that this delay "does not impact the availability of other trims in the EV6 and EV9 lineups."

More from Electrek: The news comes after Kia already said it was delaying the EV4, its entry-level electric sedan, "until further notice." It was expected to arrive in the US this year alongside the EV3, Kia's compact electric SUV that's already a top-seller in the UK, Europe, and other overseas markets.

While Hyundai didn't directly say it, since the EV3, EV4, EV6 GT, and Hyundai IONIQ 6 are built in Korea, the Trump administration's import tariffs and other policy changes are likely the biggest reason to blame here. Kia and Hyundai, like many others, are hesitant to bring new EVs to the US due to the changes. The IONIQ 6, EV6 GT, and EV9 GT join a string of other models that have either been postponed or canceled altogether.

Military GPS Jamming is Interfering with the Navigation Systems of Commercial Ships (cnn.com) 61

"Within 24 hours of the first US-Israeli strikes on Iran, ships in the region's waters found their navigation systems had gone haywire," reports CNN, "erroneously indicating that the vessels were at airports, a nuclear power plant and on Iranian land.

"The location confusion was a result of widespread jamming and spoofing of signals from global positioning satellite systems." Used by all sides in conflict zones to disrupt the paths of drones and missiles, the process involves militaries and affiliated groups intentionally broadcasting high-intensity radio signals in the same frequency bands used by navigation tools. Jamming results in the disruption of a vehicle's satellite-based positioning while spoofing leads to navigation systems reporting a false location. Though commercial vessels are not the target, the electronic interference disrupted the navigation systems of more than 1,100 commercial ships in UAE, Qatari, Omani and Iranian waters on February 28, according to a report from Windward, a shipping intelligence firm. Jamming and spoofing also slowed marine traffic moving through the Strait of Hormuz, a congested shipping lane that handles roughly 20% of the world's oil and gas exports and where precise navigation is essential, Windward's data showed.... Daily incidents have more than doubled, rising from 350 when the conflict began to 672 by March 2, the firm reported.

As use of this warfare tactic grows, experts worry the impacts could reach far beyond battlespaces.... In June 2025, electronic interference with navigation systems was thought to be a factor in the collision between two oil tankers, Adalynn and Front Eagle, off the coast of the UAE... The number of global positioning system signal loss events affecting aircraft increased by 220% between 2021 and 2024, according to data from the International Air Transport Association. Last year, IATA said that the aviation industry must act to stay ahead of the threat.

Cockpits are seeing their navigation displays "literally drift away from reality," said a commercial pilot, who didn't want to be identified because he was not permitted to speak publicly. He said that he and his colleagues have experienced map shifts, where the aircraft location appears to move up to 1 mile away from the actual flight path, false altitude information that leads to phantom "pull up" commands, and systems suggesting an aircraft was on a taxiway, a path that connects runways with various airport facilities, when taking off. These incidents force pilots to rely on manual actions that increase workload, often during the most exhausting points of long-haul flights, he said.

"Alternative navigational tools that don't rely on GPS, but instead harness quantum technology, are also in development," the article points out, "but remain a long way off operational use."
