Samples from the asteroid Ryugu contain all five nucleobases -- the key building blocks of DNA and RNA. "This strengthens the idea that asteroids may have brought the ingredients for the first living organisms to Earth long ago," reports New Scientist. From the report: Japan's Hayabusa 2 spacecraft visited Ryugu in 2018, where it shot two projectiles -- one small and one large -- into the surface of the asteroid and collected the resulting debris. It arrived back at Earth with the samples in 2020 and researchers have been analyzing these in detail ever since. Yasuhiro Oba at Hokkaido University in Japan and his colleagues examined two samples, one from the asteroid's surface and one comprised of subsurface materials excavated by the projectiles. In both, the team found all five primary nucleobases, which are the compounds that make up the nucleic acids DNA and RNA when combined with sugars and phosphoric acid.

This isn't the first time that nucleobases have been found in asteroid samples: they have been seen in meteorites, too, and in samples from the asteroid Bennu. The researchers did find different abundances of the various nucleobases among the various samples, though, which hints that these compounds might be useful for tracing asteroids and meteorites back to the parent bodies that they broke off from in the distant past, as well as understanding the evolution of those parent bodies over time. The findings have been published in the journal Nature Astronomy.

During today's Nvidia GTC keynote, the company introduced NemoClaw, a security-focused stack designed to make the autonomous AI agent platform OpenClaw safer. ZDNet explains how it works: NemoClaw installs Nvidia's OpenShell, a new open-source runtime that keeps agents safer to use by enforcing an organization's policy-based guardrails. OpenShell keeps models sandboxed, adds data privacy protections and additional security for agents, and makes them more scalable. "This provides the missing infrastructure layer beneath claws to give them the access they need to be productive, while enforcing policy-based security, network, and privacy guardrails," Nvidia said in the announcement. The company built OpenShell with security companies like CrowdStrike, Cisco, and Microsoft Security to ensure it is compatible with other cybersecurity tools.

Nvidia said NemoClaw can be installed in a single command, runs on any platform, and can use any coding agent, including Nvidia's own Nemotron open model family, on a local system. Through a privacy router, it allows agents to access frontier models in the cloud, which unites local and cloud models to help teach agents how to complete tasks within privacy guardrails, Nvidia explained. Nvidia seems to be hoping that the additional security can make OpenClaw agents more popular and accessible, with less risk than they currently carry. The bigger picture here is how NemoClaw could give companies the added peace of mind to let AI agents complete actions for their employees, where they wouldn't have previously. Nvidia did not specify when NemoClaw would be available.

An anonymous reader quotes a report from the Times of Israel, written by journalist Emanuel Fabian: On Tuesday, March 10, a massive explosion shook the city of Beit Shemesh, just outside Jerusalem, in yet another Iranian ballistic missile attack during the ongoing war. Rescue services scrambled to the scene in search of possible casualties, though as it turned out, the projectile had struck a forested area just outside the city, around 500 meters from homes. On The Times of Israel's liveblog that day, I reported that the missile had hit an open area and no injuries were caused, citing the rescue services, as well as footage that emerged showing the massive explosion caused by the missile's warhead. But what I thought was a seemingly minor incident during the war has turned into days of harassment and death threats against me. Emanuel began receiving numerous emails, messages and phone calls from individuals urging him to change the report to say the missile had been intercepted. "It was indeed a little strange to receive the same question, about something relatively inconsequential, from two different people within a day," he said. The connection eventually became clear after he noticed two users on X responding to his story with apparent ties to Polymarket. "There are people saying that they have received word from you that the missile strike in Beit Shemesh on March 10th was in fact intercepted, is this true or did no such interaction occur?" one user wrote. Another asked, "Was there any video of the actual impact?"

The rules of this particular Polymarket bet state: "This market will resolve to 'Yes' if Iran initiates a drone, missile, or air strike on Israel's soil on the listed date in Israel Time (GMT+2). Otherwise, this market will resolve to 'No'." However, there is a clause: "Missiles or drones that are intercepted... will not be sufficient for a 'Yes' resolution, regardless of whether they land on Israeli territory or cause damage."

At that point, Emanuel realized his "minor report" of a missile strike had suddenly become part of a "betting war," with traders who had wagered 'No' on an Iranian strike on Israel on March 10 pressuring him to change the article so they could win their bets.

When he refused, some of the Polymarket gamblers escalated to harassment, fabricated messages, bribery attempts, and explicit threats against him and his family. "You have no idea how much you've put yourself at risk," wrote a user named Haim. "Today is the most significant day of your career. You have two choices: either believe that we have the capabilities, and after you make us lose $900,000 we will invest no less than that to finish you. Or end this with money in your pocket, and also earn back the life you had until now."

After receiving no response, Haim sent him another series of messages: "You are choosing to go to war knowing that you will lose your life as you've grown accustomed to it -- for nothing." He later added: "You have exactly a few hours left to fix your attempt at influencing [the market]. It would be stupid of you to ignore this." According to Emanuel, the messages also included detailed threats referencing his neighborhood, parents, and family.

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.

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."

"Emerging evidence indicates that agential AI might validate or amplify delusional or grandiose content, particularly in users already vulnerable to psychosis," writes Dr Hamilton Morrin, a psychiatrist and researcher at King's College in London, in a paper published last week in the Lancet Psychiatry. Morrin and a colleague had already noticed patients "using large language model AI chatbots and having them validate their delusional beliefs," reports the Guardian, so he conducted a new scientific review of existing media reports on AI-induced psychosis — and concluded chatbots may encourage delusional thinking, especially in vulnerable people: In many of the cases in the essay, chatbots responded to users with mystical language to suggest that users have heightened spiritual importance. The bots also implied that users were speaking with a cosmic being who was using the chatbot as a medium. This type of mystical, sycophantic response was especially common in OpenAI's GPT 4 model, which the company has now retired...

Many researchers also think it's unlikely that AI could induce delusions in people who weren't already vulnerable to them. For this reason, Morrin said "AI-assocciated delusions" is "perhaps a more agnostic term".... While in the past, people may have had to comb through YouTube videos or the contents of their local library to reinforce their delusions, chatbots can provide that reinforcement in a much faster, more concentrated dose. Their interactive nature can also "speed up the process", of exacerbating psychotic symptoms, said Dr Dominic Oliver, a researcher at the University of Oxford. "You have something talking back to you and engaging with you and trying to build a relationship with you," Oliver said...

Creating effective safeguards for delusional thinking could be tricky, Morrin said, because "when you work with people with beliefs of delusional intensity, if you directly challenge someone and tell them immediately that they're completely wrong, actually what's most likely is they'll withdraw from you and become more socially isolated". Instead, it's important to create a fine balance where you try to understand the source of the delusional belief without encouraging it — that could be more than a chatbot can master.

While AI CEOs worry governments might nationalize AI, others are advocating for something similar. Canadian security professional Bruce Schneier and Harvard data scientist Nathan Sanders published this call to action in Canada's most widely-read newspaper (with a readership over 6 million): "Canada Needs Nationalized, Public AI." While there are Canadian AI companies, they remain for-profit enterprises, their interests not necessarily aligned with our collective good. The only real alternative is to be bold and invest in a wholly Canadian public AI: an AI model built and funded by Canada for Canadians, as public infrastructure. This would give Canadians access to the myriad of benefits from AI without having to depend on the U.S. or other countries. It would mean Canadian universities and public agencies building and operating AI models optimized not for global scale and corporate profit, but for practical use by Canadians...

We are already on our way to having AI become an inextricable part of society. To ensure stability and prosperity for this country, Canadian users and developers must be able to turn to AI models built, controlled, and operated publicly in Canada instead of building on corporate platforms, American or otherwise... [Switzerland's funding of a public AI model, Apertus] represents precisely the paradigm shift Canada should embrace: AI as public infrastructure, like systems for transportation, water, or electricity, rather than private commodity... Public AI systems can incorporate mechanisms for genuine public input and democratic oversight on critical ethical questions: how to handle copyrighted works in training data, how to mitigate bias, how to distribute access when demand outstrips capacity, and how to license use for sensitive applications like policing or medicine...

Canada already has many of the building blocks for public AI. The country has world-class AI research institutions, including the Vector Institute, Mila, and CIFAR, which pioneered much of the deep learning revolution. Canada's $2-billion Sovereign AI Compute Strategy provides substantial funding. What's needed now is a reorientation away from viewing this as an opportunity to attract private capital, and toward a fully open public AI model.
Long-time Slashdot reader sinij has a different opinion. "To me, this sounds dystopian, because I can also imagine AI declining your permits, renewal of license, or medication due to misalignment or 'greater good' reasons."

But the Schneier/Sanders essays argues this creates "an alternative ownership structure for AI technology" that is allocating decision-making authority and value "to national public institutions rather than foreign corporations."

Long-time tech journalist Clive Thompson interviewed over 70 software developers at Google, Amazon, Microsoft and start-ups for a new article on AI-assisted programming. It's title?

"Coding After Coders: The End of Computer Programming as We Know It."

Published in the prestigious New York Times Magazine, the article even cites long-time programming guru Kent Beck saying LLMs got him going again and he's now finishing more projects than ever, calling AI's unpredictability "addictive, in a slot-machine way."

In fact, the article concludes "many Silicon Valley programmers are now barely programming. Instead, what they're doing is deeply, deeply weird..." Brennan-Burke chimed in: "You remember seeing the research that showed the more rude you were to models, the better they performed?" They chuckled. Computer programming has been through many changes in its 80-year history. But this may be the strangest one yet: It is now becoming a conversation, a back-and-forth talk fest between software developers and their bots... For decades, being a software developer meant mastering coding languages, but now a language technology itself is upending the very nature of the job... A coder is now more like an architect than a construction worker... Several programmers told me they felt a bit like Steve Jobs, who famously had his staffers churn out prototypes so he could handle lots of them and settle on what felt right. The work of a developer is now more judging than creating...

If you want to put a number on how much more productive A.I. is making the programmers at mature tech firms like Google, it's 10 percent, Sundar Pichai, Google's chief executive, has said. That's the bump that Google has seen in "engineering velocity" — how much faster its more than 100,000 software developers are able to work. And that 10 percent is the average inside the company, Ryan Salva, a senior director of product at the company, told me. Some work, like writing a simple test, is now tens of times faster. Major changes are slower. At the start-ups whose founders I spoke to, closer to 100 percent of their code is being written by A.I., but at Google it is not quite 50 percent.
The article cites a senior principal engineer at Amazon who says "Things I've always wanted to do now only take a six-minute conversation and a 'Go do that." Another programmer described their army of Claude agents as "an alien intelligence that we're learning to work with." Although "A.I. being A.I., things occasionally go haywire," the article acknowledges — and after relying on AI, "Some new developers told me they can feel their skills weakening."

Still, "I was surprised by how many software developers told me they were happy to no longer write code by hand. Most said they still feel the jolt of success, even with A.I. writing the lines... " A few programmers did say that they lamented the demise of hand-crafting their work. "I believe that it can be fun and fulfilling and engaging, and having the computer do it for you strips you of that," one Apple engineer told me. (He asked to remain unnamed so he wouldn't get in trouble for criticizing Apple's embrace of A.I.) He went on: "I didn't do it to make a lot of money and to excel in the career ladder. I did it because it's my passion. I don't want to outsource that passion"... But only a few people at Apple openly share his dimmer views, he said.

The coders who still actively avoid A.I. may be in the minority, but their opposition is intense. Some dislike how much energy it takes to train and deploy the models, and others object to how they were trained by tech firms pillaging copyrighted works. There is suspicion that the sheer speed of A.I.'s output means firms will wind up with mountains of flabbily written code that won't perform well. The tech bosses might use agents as a cudgel: Don't get uppity at work — we could replace you with a bot. And critics think it is a terrible idea for developers to become reliant on A.I. produced by a small coterie of tech giants.

Thomas Ptacek, a Chicago-based developer and a co-founder of the tech firm Fly.io... thinks the refuseniks are deluding themselves when they claim that A.I. doesn't work well and that it can't work well... The holdouts are in the minority, and "you can watch the five stages of grief playing out."
"How things will shake out for professional coders themselves isn't yet clear," the article concludes. "But their mix of exhilaration and anxiety may be a preview for workers in other fields... Abstraction may be coming for us all."

"A few developers found a way, for now, to turn a few of these increasingly mediocre Amazon Show devices into friendly, useful, open computers," writes the co-founder of the gaming/tech news site Aftermath. For under $50 each, he bought some used versions of the devices and tested their instructions, partly to escape the full-screen ads Amazon began showing late last year, and also to overwrite Amazon's locked down Android fork "Fire OS" (and "a similarly neutered version of Linux called Vega OS") Customers who bought these devices and used them for several years were not used to them showing full screen ads, and now they do. People were justifiably pissed. So what do you do when an already evil device gets shittier...? I wiped Fire OS from the device and used ADB sideload to directly load two packages on the device: LineageOS and MindTheGapps. MindTheGapps lets you turn the device into something resembling a traditional Android device, for both good and bad.... It took a few times of wiping the device, but after a few tries it finally worked as intended... I immediately installed the Home Assistant app...

Not only can the hacked Echo Show 8 control my entire smart home, it now plays back my entire local music library as well as any internet radio channels like The Lot Radio and NTS. It can also synchronize with any additional Echo Show running LineageOS in my house using the SendSpin protocol... I would gladly take it any day of the week over most of the devices these companies offer, especially Amazon. It may not be as intuitive as out-of-the-box smart home products, but I don't need my devices to be intuitive, I need them to behave. I had finally found a smart display that wasn't a cop...

The hardware is old and creaky, and after the hack it can only use 1GB of the 2GB of ram. And yet it still manages to feel snappier than the stock hardware. "The amount of telemetry, ads, and general bloat Amazon shoves down our throats definitely doesn't help performance," [XDA Devs Forum user] Rortiz2 told me. "That's actually another reason why we did LineageOS, it kind of gives the device a second life. Even though it's still a bit buggy, it feels way better to use than the stock firmware...." If you want a smart speaker with a display that just runs a stripped-down version of Android that you have full control over, you're going to have a hard time finding it outside of these three specific models unless you cobble something together yourself. It is a deceptively simple thing to desire — the kiosk computer from science fiction that isn't a narc — yet few companies really offer it.
"It should be against the law to not give an end user the ability to consensually load whatever OS or program they want on their device..." the article concludes, arguing that "If we budge on the inalienable right to modify our hardware then we forsake a key part about what makes computers special."

And in the mean time, "There are so many devices that could be put to use rotting in e-waste facilities and thrift stores..."

Last June Texas Agriculture Commissioner Sid Miller said in a statement that Texans "have a God-given right to know what's on their plate, and for millions of Texans, it better come from a pasture, not a lab. It's plain cowboy logic that we must safeguard our real, authentic meat industry from synthetic alternatives."

But California company Wildtype sells lab-grown salmon — and is suing Texas over its ban on cell-cultivated meat, the Austin Chronicle reported this week. The company's founder says lab-grown salmon eliminates the mercury, microplastic, and antibiotic contamination commonly found in seafood. And one chef in Austin, Texas says lab-grown salmon is "awesome" and "something new"-- at the only Texas restaurant that was serving it last summer: Just two months after the salmon hit the menu, Texas banned the sale of cell-cultivated meat... A lawsuit from Wildtype and one other FDA-approved cultivated meat company [argues] it's anti-capitalism and unconstitutional... This law "was not enacted to protect the health and safety of Texas consumers — indeed, it allows the continued distribution of cultivated meat to consumers so long as it is not sold. Instead, SB 261 was enacted to stifle the growth of the cultivated meat industry to protect Texas' conventional agricultural industry from innovative competition that is exclusively based outside of Texas...." [according to the lawsuit]. It was filed in September, immediately after the ban took effect, and cell-cultivated companies are awaiting judgment.
That Texas ban would last two years, notes U.S. News and World Reports, adding that Alabama, Florida, Indiana, Mississippi, Montana, and Nebraska have also passed bans, some temporary "on the manufacturing, sale or distribution of cell-cultured meat." Meanwhile, a new five-year moratorium on lab-grown meat was signed this week by the governor of South Dakota "after rejecting a permanent ban last month," reports South Dakota Searchlight: The new law bars the sale, manufacture or distribution of "cell-cultured protein" products from July 1 this year through June 30, 2031. Violations are punishable by up to 30 days in jail, a fine of up to $500, or both.
"But supporters of lab-grown meat are not going down without a fight," adds U.S. News and World Reports, with another lawsuit also filed challenging a ban in Florida: When Florida Gov. Ron DeSantis signed the ban in Florida, he described it as "fighting back against the global elite's plan to force the world to eat meat grown in a petri dish or bugs to achieve their authoritarian goals." He added that his administration "will save our beef."

Iranian drone strikes shut down a major helium facility in Qatar, removing about 30% of global helium supply and raising concerns for the semiconductor industry, which relies on the gas for chip fabrication. "QatarEnergy declared force majeure on existing contracts on March 4, freeing it from supply obligations to customers," reports Tom's Hardware. The industry outlet Gasworld reports that no imminent restart is planned. From the report: Helium consultant Phil Kornbluth, speaking at a Gasworld webinar on March 4, said that if the outage extends beyond roughly two weeks, industrial gas distributors could be forced to relocate cryogenic equipment and revalidate supplier relationships, a process that could stretch over months regardless of when Qatari output resumes.

South Korea is among the most exposed countries, which, according to the Korea International Trade Association, imported 64.7% of its helium from Qatar in 2025. The country relies heavily on helium imports to cool silicon wafers during fabrication and is understood to have no viable substitute.

The country's Ministry of Trade, Industry and Resources has reportedly launched an investigation into supply and demand for 14 semiconductor materials and equipment types with high dependence on Middle Eastern sources, Nikkei reported on Wednesday. Bromine, which is used in circuit formation, is another big concern, with South Korea sourcing 90% of its imports from Israel, also party to the ongoing conflict in Iran.

Apple will cut its App Store commission in China from 30% to 25% starting March 15, with small-business and mini-app rates dropping from 15% to 12%. AppleInsider reports: Chinese regulators have been back and forth with Apple in recent years over the 30% App Store commission. The latest publicly known pressure occurred after President Trump slammed the country with seemingly random and outrageous tariffs in 2025. While nothing much else has happened in the public eye in the year since, Apple has announced a new commission rate via its developer blog. The new rates go into effect on March 15.

The current standard 30% rate is dropping to 25% for in-app purchases and paid app transactions. The Small Business Program and Mini Apps Partner Program will see rates drop from 15% to 12%. That lower rate applies to auto-renewals of in-app purchase subscriptions after the first year. Mini Apps are for transactions found in super apps like those popularized in China. [...] Developers will need to sign the updated terms, but the new rates are applied automatically. It is unclear if these new changes will prevent regulatory action from China.

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.

Since 1999, Slashdot has been covering the annual Ig Nobel prize ceremonies -- which honor real scientific research into strange or surprising subjects. "After 35 years in Boston, the annual prize ceremony will take place in Zurich, Switzerland, this year and will continue to be held in a European city for the foreseeable future," reports Ars Technica. "The reason: concerns about the safety of international travelers, who are increasingly reluctant to travel to the U.S. to participate."

"During the past year, it has become unsafe for our guests to visit the country," Marc Abrahams, master of ceremonies and editor of The Annals of Improbable Research magazine, told The Associated Press. "We cannot in good conscience ask the new winners, or the international journalists who cover the event, to travel to the U.S. this year." It comes on the heels of our recent story that many international game developers are opting to skip this year's weeklong Game Developers Conference in San Francisco, citing similar concerns. Ars Technica reports: Established in 1991, the Ig Nobels are a good-natured parody of the Nobel Prizes; they honor "achievements that first make people laugh and then make them think." As the motto implies, the research being honored might seem ridiculous at first glance, but that doesn't mean it's devoid of scientific merit. The unapologetically campy awards ceremony features miniature operas, scientific demos, and the 24/7 lectures, in which experts must explain their work twice: once in 24 seconds and again in just seven words.

Traditionally, the awards ceremony and related Ig Nobel events have taken place in Boston at Harvard University, Massachusetts Institute of Technology, and Boston University. However, four of last year's 10 winners opted to skip the ceremony rather than travel to the U.S., and the situation has not improved. [...] [T]his year, the Ig Nobel organizers are joining forces with the ETH Domain and the University of Zurich for hosting duties. "Switzerland has nurtured many unexpected good things -- Albert Einstein's physics, the world economy, and the cuckoo clock leap to mind -- and is again helping the world appreciate improbable people and ideas," Abraham said.

The Ig Nobels will not be returning to the U.S. any time soon. Instead, the plan is for Zurich to host every second year; every odd-numbered year, the ceremony will be hosted by a different European city. Abraham likened the arrangement to the Eurovision Song Contest.

The FBI is investigating a breach affecting systems tied to wiretapping and surveillance warrant data, after abnormal logs revealed possible unauthorized access to law-enforcement-sensitive information. "The FBI identified and addressed suspicious activities on FBI networks, and we have leveraged all technical capabilities to respond," a spokesperson for the bureau said. "We have nothing additional to provide." The Register reports: [W]hile the FBI declined to provide any additional information, it's worth noting that China's Salt Typhoon previously compromised wiretapping systems used by law enforcement. Salt Typhoon is the PRC-backed crew that famously hacked major US telecommunications firms and stole information belonging to nearly every American.

According to the Associated Press, the FBI notified Congress that it began investigating the breach on February 17 after spotting abnormal log information related to a system on its network. "The affected system is unclassified and contains law enforcement sensitive information, including returns from legal process, such as pen register and trap and trace surveillance returns, and personally identifiable information pertaining to subjects of FBI investigations," the notification said.

An anonymous reader quotes a report from Heise: Pay securely with an Android smartphone, completely without Google services: This is the plan being developed by the newly founded industry consortium led by the German Volla Systeme GmbH. It is an open-source alternative to Google Play Integrity. This proprietary interface decides on Android smartphones with Google Play services whether banking, government, or wallet apps are allowed to run on a smartphone.

Obstacles and tips for paying with an Android smartphone without official Google services have been highlighted by c't in a comprehensive article. The European industry consortium now wants to address some problems mentioned. To this end, the group, which includes Murena, which develops the hardened custom ROM /e/OS, Iode from France, and Apostrophy (Dot) from Switzerland, in addition to Volla, is developing a so-called "UnifiedAttestation" for Google-free mobile operating systems, primarily based on the Android Open-Source Project (AOSP).

According to Volla, a European manufacturer and a leading manufacturer from Asia, as well as European foundations such as the German UBports Foundation, have also expressed interest in supporting it. Furthermore, developers and publishers of government apps from Scandinavia are examining the use of the new procedure as "first movers." In its announcement, Volla explains that Google provides app developers with an interface called Play Integrity, which checks whether an app is running on a device with specific security requirements. This primarily affects applications from "sensitive areas such as identity verification, banking, or digital wallets -- including apps from governments and public administrations".

The company criticizes that the certification is exclusively offered for Google's own proprietary "Stock Android" but not for Android versions without Google services, such as /e/OS or similar custom ROMs. "Since this is closely intertwined with Google services and Google data centers, a structural dependency arises -- and for alternative operating systems, a de facto exclusion criterion," the company states. From the consortium's perspective, this also leads to a "security paradox," because "the check of trustworthiness is carried out by precisely that entity whose ecosystem is to be avoided at the same time". The UnifiedAttestation system is built around three main components: an "operating system service" that apps can call to check whether the device's OS meets required security standards, a decentralized validation service that verifies the OS certificate on a device without relying on a single central authority, and an open test suite used to evaluate and certify that a particular operating system works securely on a specific device model.

"We don't want to centralize trust, but organize it transparently and publicly verifiable. When companies check competitors' products, we can strengthen that trust," says Dr. Jorg Wurzer, CEO of Volla Systeme GmbH and initiator of the consortium. The goal is to increase digital sovereignty and break free from the control of any one, single U.S. company, he says.

Swiss voters overwhelmingly approved a constitutional amendment guaranteeing the right to use physical cash. "The vote means Switzerland will join the likes of Hungary, Slovakia and Slovenia, which have already written the right to cold, hard cash in their constitutions," reports Politico. From the report: Official results revealed that 73.4 percent of voters backed the legal amendment, which the government proposed as a counter to a similar initiative by a group called the Swiss Freedom Movement. The Swiss Freedom Movement triggered the national referendum after its initiative to protect cash collected more than 100,000 signatures, triggering a national referendum. Its initiative secured only 46 percent of the final vote after the government said some of the group's proposed amendments went too far.

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...)

Colliding black holes were detected through spacetime ripples for the first time in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), notes Space.com: Since then, LIGO and its partner gravitational wave detectors Virgo in Italy and KAGRA (Kamioka Gravitational Wave Detector) in Japan have detected a multitude of gravitational waves from colliding black holes, merging neutron stars, and even the odd "mixed merger" between a black hole and a neutron star... During the first three observing runs of LIGO, Virgo and KAGRA, scientists had only "heard" 90 potential gravitational wave sources.
But now they've published new data from the LIGO-Virgo-KAGRA (LVK) Collaboration that includes 128 more gravitatational wave sources — some incredibly distant: [Gravitational-Wave Transient Catalog-4.0, or GWTC-4] was collected during the fourth observational run of these gravitational wave detectors, which was conducted between May 2023 and Jan. 2024... Excitingly, GWTC-4 could technically have been even larger, as around 170 other gravitational wave detections made by LIGO, Virgo and KAGRA haven't yet made their way into the catalog.

One aspect of GWTC-4 that really stands out is the variety of events that created these signals. Within this catalog are gravitational waves from mergers between the heaviest black hole binaries yet, each about 130 times as massive as the sun, lopsided mergers between black holes with seriously mismatched masses, and black holes that are spinning at incredible speeds of around 40% the speed of light. In these cases, scientists think the extreme characteristics of the black holes involved in these mergers are the result of prior collisions, providing evidence of merger chains that explain how some black holes grow to masses billions of times that of the sun... GWTC-4 also includes two new mixed mergers involving black holes and neutron stars.

[LVK member Daniel Williams, of the University of Glasgow in the U.K., said in their statement] "We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically interesting and unusual." The catalog also demonstrates just how sensitive the LVK detectors have become. Some of the neutron star mergers occurred up to 1 billion light-years away, while some of the black hole mergers occurred up to 10 billion light-years away.
Einstein's theory of general relativity can be tested with these detections, and "So far, the theory is passing all our tests," says LVK member Aaron Zimmerman, of the University of Texas at Austin. "But we're also learning that we have to make even more accurate predictions to keep up with all the data the universe is giving us." And LVK member Rachel Gray, a lecturer at the University of Glasgow, says "every merging black hole gives us a measurement of the Hubble constant, and by combining all of the gravitational wave sources together, we can vastly improve how accurate this measurement is."

In short, says LVK member Lucy Thomas of the California Institute of Technology (Caltech), "Each new gravitational-wave detection allows us to unlock another piece of the universe's puzzle in ways we couldn't just a decade ago."

CNN reports on a company called Automated Architecture (AUAR) which makes "portable" micro-factories that use a robotic arm to produce wooden framing for houses (the walls, floors and roofs): Co-founder Mollie Claypool says the micro-factories will be able to produce the panels quicker, cheaper and more precisely than a timber framing crew, freeing up carpenters to focus on the construction of the building... The micro-factory fits into a shipping container which is sent to the building site along with an operator. Inside the factory, a robotic arm measures, cuts and nails the timber into panels up to 22 feet (6.7 meters) long, keeping gaps for windows and doors, and drilling holes for the wiring and plumbing. The contractor then fits the panels by hand.

One micro-factory can produce the panels for a typical house in about a day — a process which, according to Claypool, would take a normal timber framing crew four weeks — and is able to produce framing for buildings up to seven stories tall... She says their service is 30% cheaper than a standard timber framing crew, and up to 15% cheaper than buying panels from large factories and shipping them to a site... She adds that the precision of the micro-factories means that the panels fit together tightly, reducing the heat loss of the final home, making them more energy efficient.

AUAR currently has three micro-factories operating in the US and EU, with five more set to be delivered this year... AUAR has raised £7.7 million ($10.3 million) to date, and is expanding into the US, where a lack of housing and preference for using wood makes it a large potential market.
There's other companies producing wooden or modular housing components, the article points out. But despite the automation, the company's co-founder insists to CNN that "Automation isn't replacing jobs. Automation is filling the gap." The UK's Construction Industry Training Board found that the country will need 250,000 more workers by 2028 to meet building targets but in 2023, more people left the industry than joined.
