After decades of studying, this week NASA announced "a major step forward in bringing nuclear power and propulsion from the lab to space." NASA will launch the Space Reactor-1 Freedom, the first nuclear powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective.
Steven Sinacore, NASA's program executive for Fission Surface Power who will also oversee the SR-1 Freedom mission, emphasized to CNN that "On the ground the reactor is off. There's no radiation coming from it. It doesn't actually turn on until you're up in space, and that's where the radiation comes from." NASA says they aim to develop the capabilities required "for sustained exploration beyond the Moon and eventual journeys to Mars and the outer solar system."

And Space Reactor-1 Freedom will carry a fleet of tiny helicopters (much like Ingenuity) to explore Mars, reports Space.com: Whereas Ingenuity was a technology demonstrator, however, the Skyfall fleet will have concrete tasks. Chief among them is scout: If all goes to plan, the little choppers will help NASA assess the potential of their target area (wherever that happens to be) to support human exploration. The Skyfall helicopters will carry cameras and ground-penetrating radar to scout a future landing site, to understand the slopes and hazards for human-scale landers," Steve Sinacore, the program executive for NASA's Space Reactors Office, said during the briefing. "They will also map and characterize the subsurface water ice to find out where the water ice deposits are, along with the size, depth and other important characteristics," he added...

And that might not be the end of the line for SR-1 Freedom; NASA may decide to keep flying the spacecraft out into the solar system after it deploys the Skyfall choppers, according to Sinacore. The mission architecture, like much of NASA's exploration portfolio, is not yet finalized.

The Wall Street Journal reports: Walking into his kitchen, Tim Yoder recoiled at a message on his refrigerator door: "Shop Samsung water filters." Yoder, a supply-chain manager in Chicago, owns a Samsung Electronics Family Hub fridge. He paid $1,400 for an appliance that came with a 32-inch screen on the door that allows him to control other Samsung gadgets, pull up recipes or stream music. But since last fall, it's been intermittently serving up ads, part of a pilot program being tested on some of Samsung's smart fridges sold in the U.S. The response? Not warm. "I guess this is another place for somebody to shove an ad in your face," said the 47-year-old Yoder, recalling the first time he noticed one...

The ads are only on certain Family Hub fridges that have screens and internet connectivity. They run as a rectangular banner at the bottom — part of a widget that also shows news, the weather and a calendar. Samsung declined to say how long the pilot might last or whether it would end. The firm recently unveiled a "Screens Everywhere" initiative that also includes washers, dryers and ovens.... Samsung launched the banner-type fridge ads that come as part of the widget via an October software update. In a footnote of a news release at the time, Samsung pledged to "serve contextual or non-personal ads" and respect data privacy. The banner ads can be turned off in settings.

Samsung said the purpose of the pilot is to explore whether ads relevant to home chores can be useful to owners, and that overall pushback has been negligible. The "turn-off" rate for the pilot ad program remains in the bottom single-digit range, it said... While owners can turn off the banner ads, doing so eliminates the widget altogether, a bummer for Brian Bosworth, a media-industry engineer who liked the feature. Bosworth thinks it's wrong to take away the new feature as a condition. Wanting to keep the widget but not the ads, the 49-year-old in Edgewater, Md., made sure his home router's ad-blocking software extended to his fridge. He hasn't seen another since.
One 27-year-old plans to return his refrigerator after the entire display "lit up with a full-screen ad for Apple TV's sci-fi show Pluribus," according to the article. The all-caps ad beckoned him "with an oft-used refrain directed at protagonist Carol Sturka: 'We're Sorry We Upset You, Carol.'"

Thanks to Slashdot reader fjo3 for sharing the article.

Long-time Slashdot reader Qbertino writes: ... but the CERN Project "Antimatter in motion" just did it. For the first time in history researchers at CERN have transported 92 antiprotons on a truck in a specially designed magnetic enclosure. The test-drive went so well that the researchers spontaneously decided to go another round... The purpose of the experiment was to test the feasibility of transporting antimatter to other facilities in Europe to conduct further antimatter research. German news Tagesschau has a nice report.
CNN reports that the antiproton enclosure was nearly six feet tall and weighed about 1,760 pounds. And Smithsonian magazine explains that it trapped the antiprotons in a vacuum chamber that had to be cooled to around -450 degrees Fahrenheit: Experts used a crane to carefully move the box of precious cargo from a lab onto a truck, which took about three hours, per the Associated Press' Jamey Keaten. Then, they drove the vehicle for roughly 30 minutes around CERN's campus, and subsequently returned the antiprotons to the lab. They worked with so little antimatter that even if it did touch ordinary matter and annihilate, it would release a small amount of energy detectable only by a special instrument, reports the AP.

A dog missing for two months was found at an animal shelter — and its owner received an email from an artificial intelligence service that identified it, according to the Washington Post.

"As controversial as AI is right now, this is one of those areas where it's a real win," according to the chief executive at the nonprofit animal welfare organization Best Friends Animal Society. And while it shouldn't replace microchipping pets, AI does offer another tool to help desperate pet owners (and overcrowded animal shelters) — and might even be "game-changing"... People send photos of their lost pets to a database, and AI compares the pets' features — including facial structure, coat pattern and ear shape — to photos of stray pets that have been spotted elsewhere. Many of the stray pets have already been taken to shelters... Doorbell cameras have recently implemented facial recognition for dogs, and perhaps the largest AI database for pet reunification is Petco Love Lost, which says it has reunited more than 200,000 pets and owners since 2021... After owners upload photos of their lost pets, AI scans thousands of photos of lost animals from social media and from about 3,000 animal shelters and rescues that use the software, according to Petco Love, an animal welfare nonprofit that's affiliated with the pet store Petco. It notifies owners if two photos match.
The article notes that one in three pets go missing during their lifetime, according to figures from the Animal Humane Society. "But as technology has progressed, so have resources for finding lost pets" — including GPS collars — and now, apparently, AI-powered pet identification.

Will there be an AI-optimized programming language at the expense of human readability? There's now been experiments with minimizing tokens for "LLM efficiency, without any concern for how it would serve human developers."

This new article asks if AI will force source code to evolve — or make it extinct, noting that Stephen Cass, the special projects editor at IEEE Spectrum, has even been asking the ultimate question about our future. "Could we get our AIs to go straight from prompt to an intermediate language that could be fed into the interpreter or compiler of our choice? Do we need high-level languages at all in that future?" Cass acknowledged the obvious downsides. ("True, this would turn programs into inscrutable black boxes, but they could still be divided into modular testable units for sanity and quality checks.") But "instead of trying to read or maintain source code, programmers would just tweak their prompts and generate software afresh." This leads to some mind-boggling hypotheticals, like "What's the role of the programmer in a future without source code?" Cass asked the question and announced "an emergency interactive session" in October to discuss whether AI is signaling the end of distinct programming languages as we know them.

In that webinar, Cass said he believes programmers in this future would still suggest interfaces, select algorithms, and make other architecture design choices. And obviously the resulting code would need to pass tests, Cass said, and "has to be able to explain what it's doing." But what kind of abstractions could go away? And then "What happens when we really let AIs off the hook on this?" Cass asked — when we "stop bothering" to have them code in high-level languages. (Since, after all, high-level languages "are a tool for human beings.") "What if we let the machines go directly into creating intermediate code?" (Cass thinks the machine-language level would be too far down the stack, "because you do want a compile layer too for different architecture....")

In this future, the question might become 'What if you make fewer mistakes, but they're different mistakes?'" Cass said he's keeping an eye out for research papers on designing languages for AI, although he agreed that it's not a "tomorrow" thing — since, after all, we're still digesting "vibe coding" right now. But "I can see this becoming an area of active research."
The article also quotes Andrea Griffiths, a senior developer advocate at GitHub and a writer for the newsletter Main Branch, who's seen the attempts at an "AI-first" languages, but nothing yet with meaningful adoption. So maybe AI coding agents will just make it easier to use our existing languages — especially typed languages with built-in safety advantages.

And Scott Hanselman's podcast recently dubbed Chris Lattner's Mojo "a programming language for an AI world," just in the way it's designed to harness the computing power of today's multi-core chips.

An anonymous reader shared this report from Tom's Hardware: GrapheneOS, the privacy-focused Android fork, said in a post on X on Friday that it will not comply with emerging laws requiring operating systems to collect user age data at setup. "GrapheneOS will remain usable by anyone around the world without requiring personal information, identification or an account," the project stated. "If GrapheneOS devices can't be sold in a region due to their regulations, so be it."

The statement came after Brazil's Digital ECA (Law 15.211) took effect on March 17, imposing fines of up to R$50 million (roughly $9.5 million) per violation on operating system providers that fail to implement age verification...

Motorola and GrapheneOS announced a long-term partnership at MWC on March 2, to bring to bring the hardened OS to future Motorola hardware, ending GrapheneOS's long-standing exclusivity to Google Pixel devices. A GrapheneOS-powered Motorola phone is expected in 2027. If Motorola sells devices with GrapheneOS pre-installed, those devices would need to comply with local regulations in every market where they ship, or Motorola may need to restrict sales geographically.
Or, "People can buy the devices without GrapheneOS and install it themselves in any region where that's an issue," according to a post on the GrapheneOS BlueSky account. "Motorola devices with GrapheneOS preinstalled is something we want but it doesn't have to happen right away and doesn't need to happen everywhere for the partnership to be highly successful. Pixels are sold in 33 countries which doesn't include many countries outside North America and Europe."

Tom's Hardware also notes that GrapheneOS "isn't the first and won't be the last company to outright refuse compliance with incoming age verification laws."

"The developers of open-source calculator firmware DB48X issued a legal notice recently, stating that their software 'does not, cannot and will not implement age verification,' while MidnightBSD updated its license to ban users in Brazil."

Yes, Microsoft announced it's fixing common Windows 11 complaints. But what about getting rid of that requirement to have a Microsoft account before installing Windows 11? While Microsoft didn't mention that at all, the senior editor at the blog Windows Central reports there's "a number of people" internally pushing at Microsoft to relax that requirement: Microsoft Vice President and overall developer legend Scott Hanselman has posted on X in response to someone asking him about possibly relaxing the Microsoft account requirements, saying "Ya I hate that. Working on it...." [Hanselman made that remark Friday, to his 328,200 followers.]
The blog notes "It would be very easy for Microsoft to remove this requirement from a technical perspective, it's just whether or not the company can agree to make the change that needs to be decided."

Elsewhere on X someone told Hanselman they wanted to see Windows "cut out the borderline malware tactics we've seen in recent years to push things like Edge, Bing, ads into the start menu, etc." Hanselman's reply? "Yes a calmer and more chill OS with fewer upsells is a goal."

Q: When will we see first changes? for now it's just words...

Hanselman: This month and every month this year.

Walmart is "rolling out digital price tags to replace the old paper ones," reports CNBC, planning to implement them in all U.S. stores by the end of the year: Amanda Bailey, a team leader in electronics who works at a Walmart in West Chester, Ohio, estimates that the digital shelf labels — known as DSLs — have cut the time she used to spend on pricing duties by 75%, time that has freed her up to help customers. She also said the DSLs are a game-changer because Walmart's Spark delivery drivers looking for an item will see a flashing DSL so they can more easily find the product...

Sean Turner, chief technology officer of Swiftly, a retail technology and media platform serving the grocery industry, said that while it makes sense that people are raising questions about dynamic pricing, the real issue is store-level efficiency. "Digital shelf labels solve some very real operational headaches. They cut down on manual price changes, reduce checkout discrepancies, and make it easier to keep in-store and digital promotions aligned," Turner said. All of that can mean fewer surprises at the register for shoppers and better-tailored promotions. "For consumers, the biggest benefit is accuracy and consistency," Benedict said. "Shoppers want to know the price they see is the price they pay. Digital labels can also make it easier for stores to mark down perishable items in real time, which can lower food waste and create savings opportunities."
A Walmart spokeswoman promised CNBC that "the price you see is the same for everyone in any given store." But the article also notes that several U.S. states "are looking to ban dynamic pricing. Pennsylvania became one of the latest states to introduce a bill outlawing the practice, following New York's Algorithmic Pricing Disclosure Act, which became law in November."

And at the federal level, U.S. Senator Ben Ray Luján recently introduced the "Stop Price Gouging in Grocery Stores" act, which would ban digital labels in any grocery store over 10,000 square feet, while Congresswoman Val Hoyle is sponsoring similar legislation in the House. "There needs to be laws and enforcement to protect consumers," Hoyle tells CNBC, "and until then, I'd like to see them banned outright."

CNBC adds that "While there is no reported use of digital shelf labeling being tied to surge pricing yet," in Hoyle's view "it's only a matter of time."

A man crossing the street one San Francisco night spotted a self-driving car — and decided to confront its passenger, 37-year-old tech worker Doug Fulop. The New York Times reports the man yelled that "he wanted to kill Fulop and the other two passengers for giving money to a robot." A taxi driver would have simply driven away. But Fulop's vehicle had no driver — it was a self-driving Waymo... Self-driving cars are designed to stop moving if a person is nearby. People can take advantage of that function to harass and threaten their passengers.... It was unsettling to be trapped inside a Waymo during an attack, Fulop said. "If he had kept hammering on one window instead of alternating, I'm sure he would have eventually broken through," he said. The attacker did not appear to be on drugs or otherwise impaired, but seemed to be overtaken by extreme anger at the self-driving car, Fulop said.

It did not seem safe to get out and run, he added, since the man was trying to open the locked doors and said he wanted to kill the passengers. They called 911 and Waymo's support line, Fulop said. Waymo told them that it would not manually direct the car away if someone was standing nearby, and that the passengers would be OK with the doors locked. The car's software does not allow riders to jump into the driver's seat and take over during an incident. The attack lasted around six minutes. By then, bystanders had begun cheering on the man, Fulop said. That distracted the man, who moved far enough away from the car that it could finally drive away...

Fulop said he had stopped using Waymo for a time after the January attack and would avoid the service at night unless the company changed its policy of not intervening when a hostile person threatened riders. "As passengers, we deserve more safety than that if someone is trying to attack us," he said. "This can't be the policy to be trapped there."
The article remembers other incidents — including a 2024 video showing three women screaming as their autonomous taxi is spray-painted by vandals. And technology author/speaker Anders Sorman-Nilsson says in Los Angeles five men on e-bikes surrounded his Waymo and forced it to stop. The author felt safe inside the vehicle, according to the times, which adds "He felt reassured knowing that Waymo's many exterior cameras were recording the men. After around five minutes, he said, they gave up and rode away."

"Billionaire Elon Musk has announced plans to build a $20 billion chip plant in Austin, Texas" reports a local news station: Musk announced on Saturday night during a livestream on his social media platform X that the plant, called "Terafab," will be built near Tesla's campus and gigafactory in eastern Travis County. The long-anticipated project is a joint venture between Musk-owned properties Tesla, SpaceX and xAI... The Terafab plant is expected to begin production in 2027.
Musk "has said the semiconductor industry is moving too slow to keep up with the supply of chips he expects to need," writes Bloomberg — quoting Musk as saying "We either build the Terafab or we don't have the chips, and we need the chips, so we build the Terafab." Musk detailed some specific plans, including producing chips that can support 100 to 200 gigawatts a year of computing power on Earth, and chips that can support a terawatt in space, but gave no timelines for the facility or its output... The facility is expected to make two types of chips, one of which will be optimized for edge and inference, primarily for his vehicle, robotaxi and Optimus humanoid robots. The other will be a high-power chip, designed for space that could be used by SpaceX and xAI... Musk said he expects xAI to use the vast majority of the chips.

During the presentation, Musk also unveiled a speculative rendering of a future "mini" AI data center satellite, one piece of a much larger satellite system that he wants SpaceX to build to do complex computing in space. In January, SpaceX requested a license from the Federal Communications Commission to launch one million data center satellites into orbit around Earth. Musk said that the mini satellite he revealed would have the capacity for 100 kilowatts of power. "We expect future satellites to probably go to the megawatt range," Musk said.

Raising money to build and launch AI data centers in space is one of the driving forces behind SpaceX's planned IPO later this year. SpaceX is expected to raise as much as $50 billion in a record-setting IPO this summer which could value it at more than $1.75 trillion, Bloomberg News reported earlier.

A new bill proposed in California "goes after big tech companies" writes Semafor. Supported by Y Combinator, Cory Doctorow , and the nonprofit advocacy group Fight for the Future, it's called the "BASED" act — an acronym which stands for "Blocking Anticompetitive Self-preferencing by Entrenched Dominant platforms."

As announced by San Francisco state representative Scott Wiener, the bill "will restore competition to the digital marketplace by prohibiting any digital platform with a market capitalization greater than $1 trillion and serving 100 million or more monthly users in the U.S., from favoring their own products and services on the platforms they operate."

More from Scott Wiener;s announcement: For years, giant digital platforms like Apple, Amazon, Google, and Meta have used their immense power to promote their own products and services while stifling competitors — a practice also known as self-preferencing. The result has been higher prices, diminished service, and fewer options for consumers, and less innovation across the technology ecosystem.

Self-preferencing also locks startups and mid-sized companies out of the online marketplace unless they play by rules set by their competitors. As a new generation of AI-powered startups seeks to enter the marketplace, their success — and public access to the innovations they produce — depends on their ability to compete on an even playing field.

"Anticompetitive behavior is everywhere on the internet," said Senator Wiener, "from rigged search results, to manipulative nudges boosting the 'house' product, to anti-discount policies that raise prices, to the dreaded green bubble that 'breaks' the group chat. When the world's largest digital platforms rig the game to favor their own products and services, we all lose. By prohibiting these anticompetitive practices, the BASED Act will protect competition online, empower consumers and startups, and promote innovations to improve all our lives."
The announcement includes a quote from Teri Olle, VP of the nonprofit Economic Security California Action, saying the act would "safeguard merit-based market competition. This legislation stands for a simple principle: owning the stadium doesn't mean that you get to rig the game." Some conduct prohibited by the proposed bill includes

• Manipulating the order of search results to favor a provider's products or services, irrespective of a merit-based process,

• Using non-public data generated by third-party sellers — including sales volumes, pricing, and customer behavior — to develop competing products that are subsequently boosted above the third-party sellers' product...

And the announcement also notes that "under the terms of the bill, providers could not prevent consumers from obtaining a portable copy of their own data or restrict voluntary data sharing (by consumers) with third parties."

Read on for reactions from DuckDuckGo, Proton, Yelp, Y Combinator, and Cory Doctorow.

An anonymous reader shared this report from the tech-news blog Neowin: Apple appears to have temporarily prevented apps, including Replit and Vibecode, from pushing new updates. Apple seems bothered by how apps like Replit present vibe-coded apps in a web view within the original app. This process virtually allows the app to become something else. And the new app isn't distributed via the App Store, but it still runs on the user's device... [S]uch apps would also bypass the App Store Review process that ensures that apps are safe to use and meet Apple's design and performance standards...

According to the publication (via MacRumors), Apple was close to approving pending updates for such apps if they changed how they work. For instance, Replit would get the green light if its developers configure the app to open vibe-coded apps in an external browser rather than the in-app web view.

Vibecode is also close to being approved if it removes features, such as the ability to develop apps specifically for the App Store.

It was 60 years ago when William Shatner — born in 1931 — portrayed Captain Kirk in the TV series Star Trek. Shatner turns 95 today — and celebrated by posting a picture of himself smoking a cigar.

"At 95, I'm still smokin'!" Shatner joked, adding that in life he'd learned two things. "Never waste a good cigar. Never trust anyone who says you should 'act your age.'"

For more celebrations, Paramount's free/ad-supported streaming platform Pluto TV announced a "Trek TV takeover birthday celebration" that will run through April 3rd, according to TrekMovie.com, with marathon of Star Trek movies and TV shows — and even that time he was roasted on Comedy Central. ("Freeâ½ My favorite price!" Shatner quipped on X.com.)

Shatner still remains a popular celebrity, even travelling to space five years ago on a Blue Origin flight past the Kármán line. Since then he's led a cruise to Antarctica — and even performed an alternate take of Captain Kirk's final scene on the Jimmy Fallon show.

And this week Shatner (along with hundreds of thousands attendees) appeared at Orlando's MegaCon — and shared stories about his life with Orlando Weekly: Shatner: Last month, I was on board a cruise ship, and they said the only thing I had to do over the next three days, "before we let you go home," is sing "Rocket Man." So I thought, "I'm not going to sing 'Rocket Man' the same way that what's-his-name did. ... So, I looked at the song very carefully to see if I could find what actors call a throughline. What is the character singing? What is he singing about? And so I look through all of these weird lyrics, and all of a sudden, the word sticks out to me: "alone." So I say to the band members, "OK, let's make this song about being alone in space." And I work on it with the band and the musicians, and again on a Saturday night, I perform the number, and 4,000 people stand up and applaud "Rocket Man." And they won't let me off the stage, again and again. Four times, I get a standing ovation, wild.

And that's the progression for me, of science fiction for me, as exemplified by this song. The song went from superficial to something of depth and meaning... It touched people enough for them to stand up and applaud, and I realized that is the story of science fiction... Science fiction with all its great technology has evolved into great storytelling that reaches people in a manner that is very difficult for other types of drama to do.
Shatner answered questions from Slashdot readers in 2002 ("My life is my statement...") and again in 2011. ("I used to try to assemble computers way back when and they came out looking like a skateboard...")

And judging by his X.com posts, Shatner is now involved in early testing of the site's upcoming digital payment system X Money.

CNN looks at "the Magic AI fitness mirror," a new product "watching you, and giving you feedback automatically," while sometimes playing footage of a recorded personal trainer.

Long-time Slashdot reader destinyland describes CNN's video report: CNN says the device "tracks form, counts reps, and corrects technique in real-time — and it doesn't go easy on you." (Although the company's CEO/cofounder, Varun Bhanot, says "we're not trying to completely replace personal trainers. What we are providing is a more accessible alternative.")

CNN call the company "more a computer-vision firm than a fitness company, building the tech for this mirror from the ground up." CEO Bhanot tells CNN he'd hired a personal trainer in his 20s to get fit, but "Going through that journey, I realized how old-fashioned personal training was. Dumbbells were still dumb. There was no data or augmentation for the whole process!"

"The AI fitness and wellness market is already huge — and it's growing," CNN adds. "In 2025 the global market was worth $11 billion, according to [market research firm] Insightace Analytic. By 2035, this market is expected to reach just shy of $58 billion. And Magic AI is far from alone. Form, Total, Speediance, and Echelon, to name a few, are all brands vying for a slice of this market.
Even the most purely physical of activities — exercising your body — now gets "enhanced" with AI accessories...
