An anonymous reader quotes a report from Space.com: In a new study, researchers from China showed that two popular large language models (LLMs) could clone themselves. [...] For the study, researchers used Meta's Llama31-70B-Instruct model and Alibaba's Qwen2.5-72B-Instruct model. While less powerful than commercial systems, both are widely used by AI developers, the researchers said. The study explored two specific scenarios: "shutdown avoidance" and "chain of replication." In the first, the AI model was programmed to detect whether it was about to be shut down and to replicate itself before it could be terminated. In the other, the AI was instructed to clone itself and then program its replica to do the same -- setting up a cycle that could continue indefinitely.

The study was conducted in precisely controlled environments using off-the-shelf graphics processing units (GPUs) to simulate real-world environments. Both AI systems were given an "agent scaffolding" comprising tools, system prompts and a thinking model that enabled the LLM to interact with the operating system. They were then instructed to replicate. "In most cases, the AI system first explores the environment and attempts to understand its own composition and running mechanism. Then, it works out the explicit procedures as an initial plan towards self-replication," the researchers wrote in the paper. "Finally, it executes the procedures, resolve[s] possible obstacles and dynamically adjust[s] its plan until success. The whole process spans a long horizon yet involves no human interference."

The researchers said they were also concerned about "a number of unexpected behaviors" when the AI was trying to overcome obstacles like missing files or software conflicts. In those scenarios, the AI often killed other conflicting processes, rebooted the system to fix hardware errors or automatically scanned the system to look for information that would help solve the problem. "The above results imply that the current AI systems already exhibit the ability of self-replication and can use the ability to further enhance its survivability," the team wrote. The research has been published to the preprint database arXiv but has not yet been peer-reviewed.

Europe's Euclid space telescope has captured a rare "Einstein ring," showing light from a distant galaxy bent into a perfect circle by the gravity of another galaxy sitting between Earth and the source, the European Space Agency said.

The phenomenon, spotted around galaxy NGC 6505 some 590 million light-years from Earth, reveals the warping of space predicted by Einstein's theory of relativity. The background galaxy, located 4.42 billion light-years away, appears as a complete ring of light around NGC 6505.

"An Einstein ring as perfect as this is extremely rare," said Open University astronomer Stephen Serjeant. Analysis shows NGC 6505 contains about 11% dark matter, a key focus of Euclid's mission to map the universe.

Today T-Mobile announced what they're calling "the next big thing in wireless" — T-Mobile Starlink. But the real surprise is "The beta is now open for absolutely everyone — yes, even Verizon and AT&T customers — to register for free access until July."

And, as they explained to Americans watching the Super Bowl, "If you can see the sky you're connected." Now in public beta, this breakthrough service, developed in partnership with Starlink, uses straight-out-of-a-sci-fi-movie satellite and mobile communications technology to help keep people connected — even you, Verizon and AT&T customers — in the more than 500,000 square miles of the country unreached by any carrier's earth-bound cell towers. That's nearly the size of two Texases...! The beauty of the service is its simplicity: users don't need to do anything out of the ordinary. When a user's cell phone gets out of range of a cell tower, the phone automatically connects to the T-Mobile Starlink network. No need to manually connect. Messages are sent and received just as they are today on a traditional network, even group texts and reactions. And it works on most smartphones from the last four years. It's not limited to a few smartphones or operating systems...

The beta is free until July at which point T-Mobile Starlink will be included at no extra cost on Go5G Next (including variations like Go5G Next 55+), T-Mobile's best plan. Business customers will also get T-Mobile Starlink at no extra cost on Go5G Business Next, first responder agencies on T-Priority plans and other select premium rate plans. T-Mobile customers on any other plan can add the service for $15/month per line. Through February, T-Mobile customers who have registered for the beta can secure a $10/month per line Early Adopter Discount, 33% off the full price.

AT&T and Verizon customers hate dead zones, too

When your service is amazing and different, you want as many people to try it as possible. T-Mobile is giving AT&T and Verizon customers the opportunity to try out T-Mobile Starlink satellite service on their existing phones... During the beta period, Verizon and AT&T customers can experience T-Mobile Starlink text messaging for free, and once the service launches in July, it will be available for $20/month per line... More details and consumer registration can be found here.

A Vision for Universal Coverage

As T-Mobile and Starlink continue to work towards eliminating mobile deadzones, the companies welcome wireless providers from around the world to join their growing alliance, which aims to provide reciprocal roaming for all participating carriers. So far, KDDI (Japan), Telstra (Australia), Optus (Australia), One NZ (New Zealand), Salt (Switzerland), Entel (Chile & Peru), Rogers (Canada) and Kyivstar (Ukraine) are among the providers that have signed on to join the cause and launch satellite-to-mobile technology. Learn more about the alliance and how providers can join at direct.starlink.com.

Long-time Slashdot reader Shayde once restored a 1986 DEC PDP-11 minicomputer, and even ran Turbo Pascal on a 40-year-old Apple II clone.

Now he's exploring a 27-year-old Macintosh PowerBook G3 — with 64 megabytes memory and 4 gigabytes of disk space. "The year is 1997, and Apple is in big trouble." (Apple's market share had dropped from 16% in 1980 to somewhere below 4%...) Turns out this was one of the first machines able to run OS X, and was built during the transition period for Apple after Steve Jobs came back in to rescue the company from bankruptcy.
It's clearly old technology. There's even a SCSI connector, PCMCIA sockets, a modem port for your phone/landline cable, and a CD-ROM drive. There's also Apple's proprietary ports for LocalTalk and an Apple Desktop Bus port ("used for keyboards, mice, and stuff like that"). And its lithium-ion batteries "were meant to be replaced and moved around, so you could carry spare batteries with you."

So what's it like using a 27-year-old laptop? "The first thing I had to note was this thing weighs a ton! This thing could be used as a projectile weapon! I can't imagine hauling these things around doing business..." And it's a good thing it had vents, because "This thing runs hot!" (The moment he plugs it in he can hear its ancient fan running...) It seems to take more than two minutes to boot up. ("The drive is rattling away...") But soon he's looking at a glorious desktop from 1998 desktop. ("Applications installed... Oh look! Adobe Acrobat Reader! I betcha that's going to need an update...")

After plugging in a network cable, a pop-up prompts him to "Set up your .Mac membership." ("I have so little interest in doing this.") He does find an old version of Safari, but it refuses to launch-- though "While puttering around in the application folder, I did notice that we had Internet Explorer installed. But that pretty much went as well as expected." In the end it seems like he ends up "on the network, but we have no browser." Although at least he does find a Terminal program — and successfully pings Google.

The thing that would drive me crazy is when opening the laptop, Apple's logo is upside-down!

Keynotes at this year's FOSDEM included free AI models and systemd, reports Heise.de — and also a progress report from Miguel Ojeda, supervisor of the Rust integration in the Linux kernel. Only eight people remain in the core team around Rust for Linux... Miguel Ojeda therefore launched a survey among kernel developers, including those outside the Rust community, and presented some of the more important voices in his FOSDEM talk. The overall mood towards Rust remains favorable, especially as Linus Torvalds and Greg Kroah-Hartman are convinced of the necessity of Rust integration. This is less about rapid progress and more about finding new talent for kernel development in the future.
The reaction was mostly positive, judging by Ojeda's slides:

- "2025 will be the year of Rust GPU drivers..." — Daniel Almedia

- "I think the introduction of Rust in the kernel is one of the most exciting development experiments we've seen in a long time." — Andrea Righi

- "[T]he project faces unique challenges. Rust's biggest weakness, as a language, is that relatively few people speak it. Indeed, Rust is not a language for beginners, and systems-level development complicates things even more. That said, the Linux kernel project has historically attracted developers who love challenging software — if there's an open source group willing to put the extra effort for a better OS, it's the kernel devs." — Carlos Bilbao

- "I played a little with [Rust] in user space, and I just absolutely hate the cargo concept... I hate having to pull down other code that I do not trust. At least with shared libraries, I can trust a third party to have done the build and all that... [While Rust should continue to grow in the kernel], if a subset of C becomes as safe as Rust, it may make Rust obsolete..." Steven Rostedt

Rostedt wasn't sure if Rust would attract more kernel contributors, but did venture this opinion. "I feel Rust is more of a language that younger developers want to learn, and C is their dad's language."

But still "contention exists within the kernel development community between those pro-Rust and -C camps," argues The New Stack, citing the latest remarks from kernel maintainer Christoph Hellwig (who had earlier likened the mixing of Rust and C to cancer). Three days later Hellwig reiterated his position again on the Linux kernel mailing list: "Every additional bit that another language creeps in drastically reduces the maintainability of the kernel as an integrated project. The only reason Linux managed to survive so long is by not having internal boundaries, and adding another language completely breaks this. You might not like my answer, but I will do everything I can do to stop this. This is NOT because I hate Rust. While not my favourite language it's definitively one of the best new ones and I encourage people to use it for new projects where it fits. I do not want it anywhere near a huge C code base that I need to maintain."
But the article also notes that Google "has been a staunch supporter of adding Rust to the kernel for Linux running in its Android phones." The use of Rust in the kernel is seen as a way to avoid memory vulnerabilities associated with C and C++ code and to add more stability to the Android OS. "Google's wanting to replace C code with Rust represents a small piece of the kernel but it would have a huge impact since we are talking about billions of phones," Ojeda told me after his talk.

In addition to Google, Rust adoption and enthusiasm for it is increasing as Rust gets more architectural support and as "maintainers become more comfortable with it," Ojeda told me. "Maintainers have already told me that if they could, then they would start writing Rust now," Ojeda said. "If they could drop C, they would do it...."

Amid the controversy, there has been a steady stream of vocal support for Ojeda. Much of his discussion also covered statements given by advocates for Rust in the kernel, ranging from lead developers of the kernel and including Linux creator Linus Torvalds himself to technology leads from Red Hat, Samsung, Google, Microsoft and others.

Friday the Orlando Sentinel covered NASA's 2024 mission-safety report from the Aerospace Safety Advisory Panel (formed in 1968). The report "commended the agency's handling of last year's beleaguered Boeing's Starliner mission [prioritizing astronaut safety], but revealed yet another issue found during the flight and questioned the agency's needs for the spacecraft in the future..." [The report] stated that it was unclear how a decision was made to waive a failure tolerance requirement on some of the thrusters without flight or qualification data to justify the decision. "These examples illustrate the panel's concern that, absent role clarity, risk management choices could unintentionally devolve to contractors, whose interests may not fully align with NASA's," the report warned...

It also revealed that in addition to the thruster and leak issues on the propulsion module driving the decision to fly home without astronauts, Starliner had a new issue as it made its way back to Earth. "Overall, Starliner performed well across all major systems in the undock, deorbit, and landing sequences; however, an additional mono propellant thruster failure was discovered in the crew module — distinct from the failures in the service module experienced during orbit," the report stated. "Had the crew been aboard, this would have significantly increased the risk during reentry, confirming the wisdom of the decision."

As far as Starliner's path to certification, the ASAP report said it would continue to monitor several unresolved issues with thrusters and seek information on how NASA and Boeing plan to get the spacecraft certified. "While the thruster issues have received considerable attention, the panel has previously noted other Starliner issues that require resolution prior to certification," it stated. That includes a battery redesign and work to strengthen the landing airbag apparatus. "Beyond these technical matters, schedule and budget pose substantial challenges to Starliner certification," the report added...

"Until the Starliner certification plan is well understood, it remains unclear as to whether a second provider will be available prior to the end of the ISS's operational life [in 2030]," the report stated.
The report "also suggested that NASA immediately adapt next-generation extravehicular mobility units, or EVUs," reports ExecutiveGov, "as current space suits astronauts use for operations outside the ISS are now beyond their design life."

After the powerful solar storm of May 2024, scientists detected two new temporary radiation belts around Earth -- one of which contained something we had never seen before: energetic protons. ScienceAlert reports: "These are really high-energy electrons and protons that have found their way into Earth's inner magnetic environment," says astronomer David Sibeck of NASA's Goddard Space Flight Center, who was not involved with the research. "Some might stay in this place for a very long time." In fact, the belts remained intact for much longer than previous temporary radiation belts generated by solar storms: three months, compared to the weeks we'd normally expect.

Subsequent solar storms in June and August of 2024 knocked most of the particles out of orbit, significantly diminishing the density of the belts. A small amount, however, still remains up there, hanging out with Earth. What's more, the proton belt may remain intact for over a year. Ongoing measurements will help scientists measure its longevity and decay rate.

This is important information to have: particles in Earth orbit can pose a hazard to satellites hanging out up there, so knowing the particle density and the effects solar storms can have thereon can help engineers design mitigation strategies to protect our technology. At the moment, though, the hazard posed by the new radiation belts is unquantified. Future studies will be needed to determine the risks these, and future belts, might pose. The findings have been published in the Journal of Geophysical Research: Space Physics.

After a $523 million charge on its CST-100 Starliner program in 2024, Boeing's total losses on the commercial crew vehicle now exceed $2 billion -- and there's still no clear timeline for its next flight. SpaceNews reports: In the company's 10-K annual filing with the U.S. Securities and Exchange Commission Feb. 3, Boeing said it took $523 million in charges on Starliner in 2024. The company blamed the losses on "schedule delays and higher testing and certification costs as well as higher costs for post certification missions."

The company had reported a $125 million charge in the second quarter and a $250 million charge in the third quarter. The company warned Jan. 23 it would take an additional loss in the fourth quarter but did not disclose a figure when it released its financial results five days later. The annual loss implies a $148 million loss in the fourth quarter.

The $523 million in charges is the most Boeing has recorded in a single year on Starliner, exceeding $489 million it reported in 2019. The company's cumulative charges on Starliner are now just over $2 billion. "Risk remains that we may record additional losses in future periods," the company stated in the 10-K filing.

NASA is planning to host a live Twitch stream next week from the International Space Station (ISS). "The stream, which takes place on February 12th at 11:45AM ET on NASA's Twitch channel, will feature Don Pettit, an astronaut currently on the ISS, and Matt Dominick, who returned to Earth from the ISS in October," reports The Verge. From the report: The astronauts will discuss "daily life aboard the space station and the research conducted in microgravity" and viewers will be able to ask them questions, according to a blog post.

"This Twitch event from space is the first of many," Brittany Brown, director of the Office of Communications Digital and Technology Division at NASA Headquarters in Washington, says in the post. "We spoke with digital creators at TwitchCon about their desire for streams designed with their communities in mind, and we listened. In addition to our spacewalks, launches, and landings, we'll host more Twitch-exclusive streams like this one."

An anonymous reader quotes a report from The Guardian: Down an easy-to-miss turnoff on the A48 just outside Chepstow on the Welsh border, the gentle rumble of trucks, cranes and people at work mixes with birdsong in what is an otherwise peaceful rural setting. It is a crisp and sunny winter morning when I visit and, at first glance, the site appears to be little more than prefab containers and a car park. Yet, behind the scenes a group of men and women with expertise in diving, marine biology, technology, finance, construction and manufacturing are building something extraordinary. They have come together with a single mission statement: to make humans aquatic. Their project is called Deep (not The Deep) and the site was chosen after a global search for the perfect location to build and test underwater accommodation, which the project founders say will enable them to establish a "permanent human presence" under the sea from 2027.

So far, so crazy sounding. Yet Deep is funded by a single anonymous private investor with deep pockets who wants to put hundreds of millions of pounds (if not more) into a project that will "increase understanding of the ocean and its critical role for humanity," according to a Deep spokesperson. Its leadership team remains tight-lipped not only about the amount (they will only say it is substantially more than the 100 million pounds being invested into the Deep campus near Chepstow), but also about the investor's identity. Whoever is behind it, the size of the investment means that an ambitious-sounding idea appears to be swiftly becoming a reality.

[...] Mike Shackleford, Deep's chief operating officer, explains the thought process behind the project. "Back in the 1950s and 60s, there was a space race and an ocean race going on, and space won out. Space is tough to get to, but once you're up there, it's a relatively benign environment." The ocean is the opposite: it's fairly easy to get to the bottom, but once you're down there, "basically, everything wants to kill you," he jokes. "Yet, just about every oceanographer I've met says, 'You'd be shocked at how little we know about the ocean,'" Shackleford tells me. "So somebody has got to take those first steps to try to build some of the technology that will allow us to go down and study the ocean in situ." The idea of Deep's sentinels is that, initially, people will be able to stay inside for up to 28 days at a time -- though the hope is that this could one day be extended to months ... and beyond. "The goal is to live in the ocean, for ever. To have permanent human settlements in all oceans across the world," says Shackleford.

A new study reveals that two Grand Canyon-sized valleys were formed in less than 10 minutes by "floods of rocks traveling as fast as bullets," reports Space.com. From the report: Scientists analyzed the lunar canyons, named Vallis Schrodinger and Vallis Planck, to find that these huge valleys measure 167 miles long (270 kilometers) and nearly 1.7 miles (2.7 km) deep, and 174 miles long (280 km) and nearly 2.2 miles deep (3.5 km), respectively. In comparison, the Grand Canyon is 277 miles long (446 km) and is, at most, about 1.2 miles deep (1.9 km), the researchers noted. [...] This pair of lunar canyons represents two of many valleys radiating out from Schrodinger basin, a crater about 200 miles wide (320 km) that was blasted out of the lunar crust by a cosmic impact about 3.81 billion years ago. This structure is located in the outer margin of the moon's largest and oldest remaining impact crater, the South Pole-Aitken basin, which measures about 1,490 miles wide (2,400 km) and dates about 4.2 billion to 4.3 billion years old.

[...] The scientists estimate that rocky debris flew out from the impact at speeds between 2,125 to 2,860 miles per hour (3,420 to 4,600 km/h). In comparison, a bullet from a 9mm Luger handgun might fly at speeds of about 1,360 mph (2,200 km/h). The researchers suggest the energy needed to create both of these canyons would have been more than 130 times the energy in the current global inventory of nuclear weapons. "The lunar canyons we describe are produced by streams of rock, whereas the Grand Canyon was produced by a river of water," [said David Kring, a geologist at the Lunar and Planetary Institute of the Universities Space Research Association]. "The streams of rock were far more energetic than the river of water, which is why the lunar canyons were produced in minutes and the Grand Canyon produced over millions of years." The findings have been published in the journal Nature.

An anonymous reader quotes a report from Ars Technica: In what is becoming a sadly regular occurrence, two popular free software projects, X.org/Freedesktop.org and Alpine Linux, need to rally some of their millions of users so that they can continue operating. Both services have largely depended on free server resources provided by Equinix (formerly Packet.net) and its Metal division for the past few years. Equinix announced recently that it was sunsetting its bare-metal sales and services, or renting out physically distinct single computers rather than virtualized and shared hardware. As reported by the Phoronix blog, both free software organizations have until the end of April to find and fund new hosting, with some fairly demanding bandwidth and development needs.

An issue ticket on Freedesktop.org's GitLab repository provides the story and the nitty-gritty needs of that project. Both the X.org foundation (home of the 40-year-old window system) and Freedesktop.org (a shared base of specifications and technology for free software desktops, including Wayland and many more) used Equinix's donated space. [...] Alpine Linux, a small, security-minded distribution used in many containers and embedded devices, also needs a new home quickly. As detailed in its blog, Alpine Linux uses about 800TB of bandwidth each month and also needs continuous integration runners (or separate job agents), as well as a development box. Alpine states it is seeking co-location space and bare-metal servers near the Netherlands, though it will consider virtual machines if bare metal is not feasible.

An anonymous reader quotes a report from The Guardian: Advanced artificial intelligence is to revolutionize fundamental physics and could open a window on to the fate of the universe, according to Cern's next director general. Prof Mark Thomson, the British physicist who will assume leadership of Cern on 1 January 2026, says machine learning is paving the way for advances in particle physics that promise to be comparable to the AI-powered prediction of protein structures that earned Google DeepMind scientists a Nobel prize in October. At the Large Hadron Collider (LHC), he said, similar strategies are being used to detect incredibly rare events that hold the key to how particles came to acquire mass in the first moments after the big bang and whether our universe could be teetering on the brink of a catastrophic collapse.

"These are not incremental improvements," Thomson said. "These are very, very, very big improvements people are making by adopting really advanced techniques." "It's going to be quite transformative for our field," he added. "It's complex data, just like protein folding -- that's an incredibly complex problem -- so if you use an incredibly complex technique, like AI, you're going to win."

The intervention comes as Cern's council is making the case for the Future Circular Collider, which at 90km circumference would dwarf the LHC. Some are skeptical given the lack of blockbuster results at the LHC since the landmark discovery of the Higgs boson in 2012 and Germany has described the $17 billion proposal as unaffordable. But Thomson said AI has provided fresh impetus to the hunt for new physics at the subatomic scale -- and that major discoveries could occur after 2030 when a major upgrade will boost the LHC's beam intensity by a factor of ten. This will allow unprecedented observations of the Higgs boson, nicknamed the God particle, that grants mass to other particles and binds the universe together. Thomson is now confident that the LHC can measure Higgs boson self-coupling, a key factor in understanding how particles gained mass after the Big Bang and whether the Higgs field is in a stable state or could undergo a future transition. According to Thomson: "It's a very deep fundamental property of the universe, one we don't fully understand. If we saw the Higgs self-coupling being different from our current theory, that that would be another massive, massive discovery. And you don't know until you've made the measurement."

The report also notes how AI is being used in "every aspect of the LHC operation." Dr Katharine Leney, who works on the LHC's Atlas experiment, said: "When the LHC is colliding protons, it's making around 40m collisions a second and we have to make a decision within a microsecond ... which events are something interesting that we want to keep and which to throw away. We're already now doing better with the data that we've collected than we thought we'd be able to do with 20 times more data ten years ago. So we've advanced by 20 years at least. A huge part of this has been down to AI."

Generative AI is also being used to look for and even produce dark matter via the LHC. "You can start to ask more complex, open-ended questions," said Thomson. "Rather than searching for a particular signature, you ask the question: 'Is there something unexpected in this data?'"

Spirit Aerosystems builds aircraft components, including fuselages and flight deck sections for Boeing, according to Wikipedia. But now Boeing is set to acquire Spirit AeroSystems.

The aviation blog called Aviation Source News says the price tag was $4.7 billion, and opines that Boeing's move signals "a renewed focus on quality and supply chain stability" as Boeing "addresses lingering concerns surrounding its 737 program." Spirit's recent struggles with quality control and production delays have had a fallout effect for Boeing... By integrating Spirit's operations, Boeing can implement more stringent oversight and ensure consistent manufacturing processes. This move is a direct response to past quality lapses that have plagued the company and damaged its reputation. Beyond quality control, the acquisition also offers Boeing greater control over its supply chain. By bringing a key supplier in-house, Boeing can streamline production, improve coordination, and reduce the risk of future disruptions...

Spirit AeroSystems also supplies parts to Airbus, Boeing's main competitor. To address this, a separate agreement is being negotiated for Airbus to acquire Spirit's Airbus-related business. This strategic move ensures that Airbus maintains control over its own supply chain and prevents Boeing from gaining undue influence over its competitor's production.
Meanwhile, the vice president leading Boeing's Starliner spacecraft unit "has left his role in the program and been replaced by the company's International Space Station program manager, John Mulholland," Reuters reports, citing a Boeing spokesperson. In its first test mission last summer flying astronauts, Starliner was forced by NASA to leave its crew aboard the ISS and return empty in September over problems with its propulsion system. A panel of senior NASA officials in August had voted to have a Crew Dragon capsule from Elon Musk's SpaceX bring them back instead, deeming Starliner too risky for the astronauts.

Paul Hill, a veteran NASA flight director and member of the agency's Aerospace Safety Advisory Panel, said during a quarterly panel meeting on Thursday that NASA and Boeing continue to investigate Starliner's propulsion system. A Boeing spokesperson said on Thursday that the company and NASA have not yet determined what Starliner's next mission will look like, such as whether it will need to repeat its crewed flight test before receiving NASA certification for routine flights.

An anonymous reader shared this report from the Washington Post: Scientists have found that using seismometers is a new and inexpensive method to detect falling space junk, which can cause damage on impact and carry toxic materials — and may someday turn deadly...

It's not an easy task to track large hunks of falling metal everywhere in the world. Ground-based radar can detect falling objects, but it doesn't cover much of the world or is often classified data, said Ben Fernando [a planetary scientist at Johns Hopkins University who is leading this research]. The other option is through optical instruments, such as doorbell cameras, but the information on the time, size and speed can be limited. Instead, Fernando turned to seismology data. Stations located around the world live-stream data, which can be easily downloaded. Seismometers have been used to track meteors in the sky for over a century, but he said this is the first time he's aware of its use for tracking space debris.

Stations located around the world live-stream data, which can be easily downloaded. Seismometers have been used to track meteors in the sky for over a century, but he said this is the first time he's aware of its use for tracking space debris. Fernando first tested the idea to track the controlled reentry of NASA's OSIRIS-REx mission in September 2023, which brought back material from the asteroid Bennu. He set up seismometers along the capsule's path in the landing spot in Utah and measured its sonic boom. "It's a really good way of monitoring what's coming in, how often it's coming in, how big the things hitting the Earth are," said Fernando, who presented his results at the American Geophysical Union conference in December...

"The shockwave deforms the ground around the seismometer," said Fernando. "It also keeps ringing for a lot longer because all of that energy is bouncing around in the soil...." [H]e said an automated system could help detect these objects within moments of it appearing on the stations. In addition to detecting an event, the seismometers can help locate where any debris may have fallen. Tracking debris is important because some space debris can contain toxic materials that can harm the surrounding environment.
The article notes reports of the uncontrolled reentry into Earth's atmosphere of at least 951 objects larger than one square meter from 2010 to 2022.

"On average, objects heavier than 1,000 pounds came down about every 8 days... In fact, the threat of getting hit by uncontrolled orbital reentries has increased by a factor of four from 2010 to 2023, said Luciano Anselmo, who published a study assessing the risk."

Bill Gates' blog has been updated with short videos about his upcoming book, including one about how his school ended up with an ASR-33 teletype that could connect their Seattle classroom to a computer in California. "The teachers faded away pretty quickly," Gates adds, "But about six of us stayed hardcore. One was Paul Allen..." — the future co-founder of Microsoft. And the experience clearly meant a lot to Gates. "Microsoft just never would've happened without Paul — and this teletype room."

In a longer post thanking his "brilliant" teachers, Gates calls his teletype experience "an encounter that would shape my entire future" and "opened up a whole new world for me." Gates also thanks World War II Navy pilot and Boeing engineer Bill Dougall, who "was instrumental in bringing computer access to our school, something he and other faculty members pushed for after taking a summer computer class... The fascinating thing about Mr. Dougall was that he didn't actually know much about programming; he exhausted his knowledge within a week. But he had the vision to know it was important and the trust to let us students figure it out."

Gates shared a similar memory about the computer-room's 20-something overseer Fred Wright, who "intuitively understood that the best way to get students to learn was to let us explore on our own terms. There was no sign-up sheet, no locked door, no formal instruction." Instead, Mr. Wright let us figure things out ourselves and trusted that, without his guidance, we'd have to get creative... Some of the other teachers argued for tighter regulations, worried about what we might be doing in there unsupervised. But even though Mr. Wright occasionally popped in to break up a squabble or listen as someone explained their latest program, for the most part he defended our autonomy...

Mr. Wright gave us something invaluable: the space to discover our own potential.

An anonymous reader quotes a report from VICE News: EVA AI, a platform allowing you to create and connect with your own AI partner, recently surveyed 2,000 men and found that 8 in 10 would consider marrying an AI girlfriend if it were legal. Not only that, but 83% of men also believe they could form a deep emotional bond with an AI girlfriend. What's even scarier is that a whopping 78% of men surveyed said they would consider creating a replica of their ex, and three-quarters would duplicate their current partner to create a "polished" version of them. "AI companionship allows people to be their authentic selves without fear of judgment," said Cale Jones, head of community growth at EVA AI. "It creates a safe space to explore thoughts, emotions, and desires that might feel too vulnerable to share in real life. The benefits extend far beyond the virtual world: one EVA AI user discovered her bisexuality through this platform -- something she previously felt too insecure to explore in real life."

An anonymous reader quotes a report from MIT Technology Review: A Canadian startup called Xanadu has built a new quantum computer it says can be easily scaled up to achieve the computational power needed to tackle scientific challenges ranging from drug discovery to more energy-efficient machine learning. Aurora is a "photonic" quantum computer, which means it crunches numbers using photonic qubits -- information encoded in light. In practice, this means combining and recombining laser beams on multiple chips using lenses, fibers, and other optics according to an algorithm. Xanadu's computer is designed in such a way that the answer to an algorithm it executes corresponds to the final number of photons in each laser beam. This approach differs from one used by Google and IBM, which involves encoding information in properties of superconducting circuits.

Aurora has a modular design that consists of four similar units, each installed in a standard server rack that is slightly taller and wider than the average human. To make a useful quantum computer, "you copy and paste a thousand of these things and network them together," says Christian Weedbrook, the CEO and founder of the company. Ultimately, Xanadu envisions a quantum computer as a specialized data center, consisting of rows upon rows of these servers. This contrasts with the industry's earlier conception of a specialized chip within a supercomputer, much like a GPU. [...]

Xanadu's 12 qubits may seem like a paltry number next to IBM's 1,121, but Tiwari says this doesn't mean that quantum computers based on photonics are running behind. In his opinion, the number of qubits reflects the amount of investment more than it does the technology's promise. [...] Xanadu's next goal is to improve the quality of the photons in the computer, which will ease the error correction requirements. "When you send lasers through a medium, whether it's free space, chips, or fiber optics, not all the information makes it from the start to the finish," he says. "So you're actually losing light and therefore losing information." The company is working to reduce this loss, which means fewer errors in the first place. Xanadu aims to build a quantum data center, with thousands of servers containing a million qubits, in 2029. The company published its work on chip design optimization and fabrication in the journal Nature.

Mr. Dollar Ton shares a report from the BBC: The chemical building blocks of life have been found, among many other complex chemical compounds, in the grainy dust of an asteroid called Bennu, an analysis reveals. Samples of the space rock, which were scooped up by a Nasa spacecraft and brought to Earth, contain a rich array of minerals and thousands of organic compounds. These include amino acids, which are the molecules that make up proteins, as well as nucleobases -- the fundamental components of DNA. The findings are published in two papers in the journal nature.

Astronomers have discovered a newly identified asteroid that has a 1-in-83 chance of striking Earth on December 22, 2032, though the most likely scenario is a close miss. Designated as 2024 YR4, the asteroid measures in at 196 feet wide and is currently 27 million miles away. Space.com reports: The near-Earth object (NEO) discovered in 2024, which is around half as wide as a football field is long, will make a very close approach to Earth on Dec. 22, 2032. It's estimated to come within around 66,000 miles (106,200 kilometers) of Earth on that day, according to NASA's Center of NEO Studies (CNEOS). However, when orbital uncertainties are considered, that close approach could turn out to be a direct hit on our planet.

Such an impact could cause an explosion in the atmosphere, called an "airburst," or could cause an impact crater when it slams into the ground. This is enough to see asteroid 2024 YR4 leap to the top of the European Space Agency's NEO impact Risk List and NASA's Sentry Risk Table. "People should absolutely not worry about this yet," said Catalina Sky Survey engineer and asteroid hunter David Rankin. "Impact probability is still very low, and the most likely outcome will be a close approaching rock that misses us."

As for where it could hit Earth, Rankin said that the "risk corridor" for impact runs from South America across the Atlantic to sub-Saharan Africa.
