An anonymous reader quotes a report from ScienceAlert: Keeping enough qubits in their ideal state long enough for computations has so far proved a challenge. In a new experiment, scientists were able to keep a qubit in that state for twice as long as normal. Along the way, they demonstrated the practicality of quantum error correction (QEC), a process that keeps quantum information intact for longer by introducing room for redundancy and error removal. The idea of QEC has been around since the mid-90s, but it's now been shown to work in real time. Part of the reason for the experiment's success was the introduction of machine learning AI algorithms to tweak the error correction routine.

"For the first time, we have shown that making the system more redundant and actively detecting and correcting quantum errors provided a gain in the resilience of quantum information," says physicist Michel Devoret, from Yale University in Connecticut. [...] Like many quantum physics experiments, this one was run at ultra-cold temperatures -- a hundred times colder than outer space, in this case. The setup has to be carefully controlled in order to protect the qubit as much as possible. The error-corrected qubit lasted for 1.8 milliseconds -- only a blink as we might experience it, but an impressive span for a qubit operating on the quantum level. Now the research team will be able to refine the process further. "Our experiment shows that quantum error correction is a real practical tool," says Devoret. "It's more than just a proof-of-principle demonstration." In this case the breakthrough was down to several different factors, rather than one change. The QEC code was actually one from 2001, but improvements to it as well as upgrades to the quantum circuit fabrication process made a difference.

"Our experiment validates a cornerstone assumption of quantum computing, and this makes me very excited about the future of this field," says Volodymyr Sivak, a research scientist at Google and formerly at Yale University.

The research has been published in Nature.

An anonymous reader quotes a report from TorrentFreak: Z-Library appears to be shrugging off a criminal investigation as if nothing ever happened. The site continues to develop its shadow library and, following a successful fundraiser, now plans to expand its services to the physical book market. Z-Library envisions a book 'sharing' market, where its millions of users can pick up paperbacks at dedicated "Z-Points" around the globe. [...] With more than 12 million books in its archive, Z-Library advertised itself as the largest repository of pirated books on the Internet. This success was briefly interrupted late last year when the U.S. Government seized the site's main domain names. The enforcement action also led to the arrest of two alleged Russian operators of the site, who now find themselves at the center of a criminal investigation. A crackdown of this magnitude usually marks the end of a pirate site, but Z-Library appears to be going in the opposite direction. The site has made a full comeback with a more 'censorship-resistant' setup and recently collected tens of thousands of dollars in donations.

In a new message, posted this week, Z-Library thanks its userbase for their generous contributions, noting that it secured all the necessary funds to ensure continued development. Apparently, this includes support for offline sharing. In addition to offering millions of ebooks, Z-Library says that it's working on a new service that will help users to share physical copies with each other. "Books you have read should not gather dust on your shelf -- instead, they can get a second life in the hands of new readers! This helps to preserve the literary heritage and spread the knowledge and ideas contained in books to more people," they write. "[W]e want to organize 'Z-Points' -- collection and storage points for books that will be the link between those who share their books and those who need them. Book owners who are willing to share them with other users can send books to the nearest Z-Point in their region. And those who need books stored in these points will be able to receive them for their use."

This sounds like a P2P competitor for traditional libraries. Interestingly, however, Z-Library believes that existing libraries are ideally suited to become Z-Points. People can also volunteer to run a Z-Point from their own homes. Running a book lending point will require quite a bit of storage space and organizational effort so fulfillment centers and third-party logistics services are also welcome to join in. The Z-Point idea is still in the planning phase. According to Z-Library, users will be able to send books by mail. These can then be loaned by others and/or sent by mail when requested. This proposal is quite different from the traditional pirate ebook library Z-Library offers now. And loaning a book to someone is generally not seen as copyright infringement either unless it's a copied ebook.

"There's an invisible monster on the loose," NASA wrote on Thursday, "barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. " This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long "contrail" of newborn stars, twice the diameter of our Milky Way galaxy... Rather than gobbling up stars ahead of it, like a cosmic Pac-Man, the speedy black hole is plowing into gas in front of it to trigger new star formation along a narrow corridor. The black hole is streaking too fast to take time for a snack. Nothing like it has ever been seen before, but it was captured accidentally by NASA's Hubble Space Telescope. "We think we're seeing a wake behind the black hole where the gas cools and is able to form stars. So, we're looking at star formation trailing the black hole," said Pieter van Dokkum of Yale University in New Haven, Connecticut...

The trail must have lots of new stars, given that it is almost half as bright as the host galaxy it is linked to... Researchers believe gas is probably being shocked and heated from the motion of the black hole hitting the gas, or it could be radiation from an accretion disk around the black hole... Because it was so weird, van Dokkum and his team did follow-up spectroscopy with the W. M. Keck Observatories in Hawaii. He describes the star trail as "quite astonishing, very, very bright and very unusual." This led to the conclusion that he was looking at the aftermath of a black hole flying through a halo of gas surrounding the host galaxy.

This intergalactic skyrocket is likely the result of multiple collisions of supermassive black holes. Astronomers suspect the first two galaxies merged perhaps 50 million years ago. That brought together two supermassive black holes at their centers. They whirled around each other as a binary black hole. Then another galaxy came along with its own supermassive black hole. This follows the old idiom: "two's company and three's a crowd." The three black holes mixing it up led to a chaotic and unstable configuration. One of the black holes robbed momentum from the other two black holes and got thrown out of the host galaxy.

"The James Webb Space Telescope has captured a new stunning image of ice giant Uranus, with almost all its faint dusty rings on display," reports CNN: The image is representative of the telescope's significant sensitivity, NASA said, as the fainter rings have only been captured previously by the Voyager 2 spacecraft and the W.M. Keck Observatory on Maunakea in Hawaii. Uranus has 13 known rings, with 11 of them visible in the new Webb image. Nine rings are classified as the main rings, while the other two are harder to capture due to their dusty makeup and were not discovered until the Voyager 2 mission's flyby in 1986.

Two other, faint outer rings not shown in this latest image were discovered in 2007 from images taken by NASA's Hubble Space Telescope, and scientists hope Webb will capture them in the future.... "The JWST gives us the ability to look at both Uranus and Neptune in a completely new way because we have never had a telescope of this size that looks in the infrared," said Dr. Naomi Rowe-Gurney, a postdoctoral research scientist and solar system ambassador for the Webb space telescope at NASA Goddard Space Flight Center in Greenbelt, Maryland. "The infrared can show us new depths and features that are difficult to see from the ground with the atmosphere in the way and invisible to telescopes that look in visible light like Hubble."
"When Voyager 2 looked at Uranus, its camera showed an almost featureless blue-green ball in visible wavelengths," NASA explains. "With the infrared wavelengths and extra sensitivity of Webb we see more detail, showing how dynamic the atmosphere of Uranus really is." On the right side of the planet there's an area of brightening at the pole facing the Sun, known as a polar cap. This polar cap is unique to Uranus — it seems to appear when the pole enters direct sunlight in the summer and vanish in the fall; these Webb data will help scientists understand the currently mysterious mechanism. Webb revealed a surprising aspect of the polar cap: a subtle enhanced brightening at the center of the cap. The sensitivity and longer wavelengths of Webb's NIRCam may be why we can see this enhanced Uranus polar feature when it has not been seen as clearly with other powerful telescopes like the Hubble Space Telescope and Keck Observatory....

This was only a short, 12-minute exposure image of Uranus with just two filters. It is just the tip of the iceberg of what Webb can do when observing this mysterious planet.

The search for life beyond Earth "follows the water," reports the Economist (since water is vital for earth's lifeforms, and the laws of chemistry are universal). "For most of the space age that insight led scientists to Mars." But... More and more, though, planetary scientists are following the water to other places — and in particular to the so-called "icy moons" that orbit Jupiter, Saturn, Neptune and Uranus, the solar system's quartet of giant gas planets. Many of those moons are either known or suspected to have oceans beneath their icy shells, kept liquid by gravitational squeezing from the planets they orbit.

On April 13th, if all goes well, a new spacecraft will blast off from French Guiana en route to Jupiter with the aim of investigating some of those watery moons up close. The European Space Agency's Jupiter Icy Moons Explorer (given the slightly contrived acronym "JUICE ") will slingshot once around Venus and three times around Earth before arriving at Jupiter in 2031.... JUICE will investigate three of the so-called Galilean moons — Callisto, Europa and Ganymede, all of which are thought to have subsurface oceans. (The fourth, Io, is arid, and so not of interest.)

Ganymede is the probe's primary target. Despite being a moon, it is bigger than the planet Mercury. Its subsurface ocean may contain more water than all of Earth's oceans combined. The probe's cameras will add much more detail to the existing, low-resolution maps of Ganymede's surface. An ice-penetrating radar will scan several kilometres below the ground. A magnetometer will take advantage of the fact that Ganymede, apparently uniquely among the solar system's moons, has a weak magnetic field that interacts with the much bigger field generated by Jupiter itself. The subtleties of that magnetic field were an early clue for the existence of an ocean, hinting at the presence of a large chunk of conductive fluid — such as salty water — beneath the surface. Better readings of the magnetic field will help scientists estimate just how big the ocean is....

Nor is JUICE the only probe on its way to Jupiter. Next year NASA will launch Europa Clipper, focused, as its name suggests, on Europa. Despite its later launch, it will take a quicker route to Jupiter, arriving a few months before JUICE . And, because there are limits to what can be discerned from orbit, both NASA and the Europeans are sketching plans for future landers that would descend to the surface of such moons to sample the seawater directly.

SpaceX plans to carry out a launch rehearsal next week of Starship, the most powerful rocket ever built, and its first test flight possibly the following week, the private space company said Thursday. Phys.Org reports: SpaceX published photos of the massive Starship, which is designed to eventually send astronauts to the Moon and beyond, on its launchpad at the company's base in Texas. "Starship fully stacked at Starbase," SpaceX said in a tweet. "Team is working towards a launch rehearsal next week followed by Starship's first integrated flight test ~ week later pending regulatory approval."

SpaceX will need a green light from the Federal Aviation Administration before being allowed to carry out the orbital test launch. SpaceX conducted a successful test-firing of the 33 Raptor engines on the first-stage booster of Starship in February. The 230-foot (69-meter) Super Heavy booster was anchored to the ground during the test-firing, called a static fire, to prevent it from lifting off.

A NASA instrument to provide unprecedented resolution of monitoring major air pollutants -- down to four square miles -- lifted off on its way to geostationary orbit at 12:30 a.m. EDT Friday. The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument will improve life on Earth by revolutionizing the way scientists observe air quality from space. From a report: "The TEMPO mission is about more than just studying pollution -- it's about improving life on Earth for all. By monitoring the effects of everything from rush-hour traffic to pollution from forest fires and volcanoes, NASA data will help improve air quality across North America and protect our planet," said NASA Administrator Bill Nelson. [...] From a fixed geostationary orbit above the equator, TEMPO will be the first space-based instrument to measure air quality over North America hourly during the daytime and at spatial regions of several square miles -- far better than existing limits of about 100 square miles in the U.S. TEMPO data will play an important role in the scientific analysis of pollution, including studies of rush hour pollution, the potential for improved air quality alerts, the effects of lightning on ozone, the movement of pollution from forest fires and volcanoes, and even the effects of fertilizer application.

TEMPO's observations will dramatically improve the scientific data record on air pollution -- including ozone, nitrogen oxide, sulfur dioxide and formaldehyde -- not only over the continental United States, but also Canada, Mexico, Cuba, the Bahamas, and part of the island of Hispaniola. "Our TEMPO slogan is 'It's about time,' which hints at TEMPO's ability to provide hourly air pollution data," said Xiong Liu, deputy principal investigator for TEMPO at the Center for Astrophysics, Harvard & Smithsonian in Cambridge, Massachusetts. "After working on the TEMPO for more than 10 years, it is about time to launch TEMPO to produce real TEMPO data and start the new era of air quality monitoring over North America."

Startups and other companies trying to capitalize on the artificial intelligence boom sparked by OpenAI are running into a problem: They can't find enough specialized computers to make their own AI software. The Information: A spike in demand for server chips that can train and run machine-learning software has caused a shortage, prompting major cloud-server providers including Amazon Web Services, Microsoft, Google and Oracle to limit their availability for customers, according to interviews with the cloud companies and their customers. Some customers have reported monthslong wait times to rent the hardware. "All the startups who are trying to get into this space...maybe they can get one [server] but there's no way they're going to get five," said Johnny Dallas, founder and CEO of Zeet, which sells software that makes it easier for engineers to run apps across multiple clouds.

The server chip shortage is a frustrating hangup for software developers trying to build AI tools hinging on recent advancements in machine-learning models. These programmers, at small and big companies alike, are developing large-language models to make personalized writing coaches or search engines that respond to questions with written answers rather than links, similar to OpenAI's ChatGPT. Many others are licensing and augmenting software from OpenAI and its rivals to create specialized customer service chatbots and research tools for corporate employees. For instance, OpenAI software is helping Morgan Stanley bankers find the best locations to auction a work of art, based on the bank's myriad internal reports on art markets.

China has invited Venezuela to join its lunar research station project as the country works to gain partners for the endeavor. SpaceNews reports: Venezuela would be the first country to join China and Russia in the International Lunar Research Station (ILRS), which is planned to be constructed in the early 2030s using super heavy-lift launch vehicles. The launches will follow smaller, precursor missions later this decade. Marglad Bencomo, executive director of the Bolivarian Agency for Space Activities (ABAE), visited China's new, national Deep Space Exploration Laboratory (DSEL) March 30 to discuss cooperation and exchanges. She was met by Wu Yanhua, former deputy director of the China National Space Administration (CNSA) and now executive vice chairman of DSEL. The two sides exchanged in-depth views on international cooperation in the field of deep space exploration, according to a DSEL statement.

Bencomo said that Venezuela was willing to sign a China-Venezuela Memorandum of Understanding as soon as possible to jointly promote the construction of international lunar research stations, according to the DSEL statement. ABAE has been invited to attend an international forum hosted by DSEL during China's national "space day," held annually on April 24 since 2016, potentially providing a platform for signing an MOU. China and Russia presented a roadmap for the joint ILRS in St. Petersburg, Russia, in 2021 and opened the project to interested parties.

Apple has been teasing plans for an India retail store since 2016. Seven years later, it's finally here. Quartz reports: The company finally released a picture of the barricade of its first ever Indian retail store in Mumbai, the country's financial hub, on Apr. 5. The store will be located in Jio World Drive -- the mall owned by India's richest man Mukesh Ambani -- in the upscale commercial hub called Bandra Kurla Complex (BKC). So far, Apple has only sold goods and offered services in India via authorized third-party retailers, or through online portals such as Amazon, Flipkart, and Paytm Mall.

Apple has chosen a prime location for its first retail outlet in India. Bandra Kurla Complex (BKC), which is morphing into the city's main business district, houses offices for multinational companies and banks. BKC recently made headlines for hosting what is being touted as India's answer to the Met Gala: the opening of the multi-disciplinary Nita Mukesh Ambani Cultural Arts Centre (NMACC). The launch of the first-of-its-kind cultural arts space was flanked by both Bollywood and Hollywood celebrities -- from Shahrukh Khan to Zendaya. "Hello Mumbai," says Apple on their website. "We are getting ready to welcome you aboard our first store in India. And raring to see where your creativity takes you at Apple BKC."

The Apple Mumbai store promises to offer one-on-one support with a Specialist, expert service and support at the Genius Bar, and product exchanges for credit towards a future purchase.

Google plans to add conversational artificial-intelligence features to its flagship search engine, Chief Executive Officer Sundar Pichai said, as it deals with pressure from chatbots such as ChatGPT and wider business issues. From a report: Advances in AI would supercharge Google's ability to answer an array of search queries, Mr. Pichai said in an interview with The Wall Street Journal. He dismissed the notion that chatbots posed a threat to Google's search business, which accounts for more than half of revenue at parent Alphabet. "The opportunity space, if anything, is bigger than before," Mr. Pichai, who also heads Alphabet, said in the interview Tuesday.

Google has long been a leader in developing computer programs called large language models, or LLMs, which can process and respond to natural-language prompts with humanlike prose. But it hasn't yet used the technology to influence the way people use search -- something Mr. Pichai said would change. "Will people be able to ask questions to Google and engage with LLMs in the context of search? Absolutely," Mr. Pichai said. With Microsoft already deploying the technology behind the ChatGPT system in its Bing search engine, Mr. Pichai is dealing with one of the biggest threats to Google's core business in years as he also faces investor pressure to cut costs. In January, Alphabet said it would eliminate about 12,000 jobs, or 6% of staff, its largest layoffs to date. Inflation and recession concerns have spurred other tech companies to cut back.

Mr. Pichai said Google hasn't yet achieved a goal of becoming 20% more productive, a target he set in September. He said the company was comfortable with its pace of change, though he wouldn't directly address the prospects of another round of layoffs. [...] When asked why the company didn't release a chatbot earlier, Mr. Pichai said Google was still trying to find the right market. "We were iterating to ship something, and maybe timelines changed, given the moment in the industry," he said. Google will continue to improve Bard with new AI models, Mr. Pichai said, while declining to comment on when the product would become freely available without a wait list.

An anonymous reader quotes a report from Ars Technica: What's even harder-core than the IBM Model M? The Model F, the keyboard that launched alongside the IBM PC in 1981. After a 2017 relaunch, new models with the original layout are here. The project, which back in 2017 relaunched a modern keyboard inspired by a compact space-saver version of IBM's classic Model F, is launching its second generation of brand-new premium input devices, and this time, various layouts will be available. [...]

Enter the New Model F Keyboards project. "Ellipse" launched it in 2017 and attracted over $300,000 worth of orders, even at $399 each. Aside from the not-inconsiderable price, what put the author off was the layout. Space-saving and reduced-footprint keyboards are very popular among serious keyboard collectors, and the project chose two space-saver layouts from IBM's 4704 terminal, dubbed the Kishsaver after the collector who described it. The F77 layout has a numeric keypad, but no function keys; the even smaller F62 layout omits the keypad, or as the cool kids call it, it's a TKL layout, which we are informed stands for tenkeyless, presumably because it has 15 fewer keys.

Which is why the FOSS desk's bank account would tremble in fear if it were not an inanimate table in a database somewhere, because the Model F project has announced a new range, including full-size and compact 104-key layouts and most appealing to this large and heavy-handed vulture, a replica of the 122-key IBM Battleship, one of which we've been hunting for over a decade. The project occasionally has refurbished original IBM units. Now, though, a brand-new one is a $420 option. If that isn't exclusive enough, your correspondent also working on a model with beam springs, the mechanism from 1970s IBM business products. The first model of the brand new beam spring units is a mere $579.

theodp writes: Are you ready to rock it with #datascience?" asks a tweet from Club for the Future, the tax-exempt foundation founded and funded by Jeff Bezos's Blue Origin, which is partnering with Microsoft's Hacking STEM to show how data science is used to determine a Go/No-Go launch of a Blue Origin New Shepard rocket. Interestingly, while Amazon founder Bezos and Microsoft CEO Satya Nadella are big backers of nonprofit Code.org and joined other tech CEOs for CS last fall to get the nation's Governors to "update the K-12 curriculum, for every student in every school to have the opportunity to learn computer science," Microsoft and Blue Origin have opted to teach kids aged 11-15 good old-fashioned Excel skills in their Introduction to the Data Science Process mini-course, not Python or R.

"Excel is a tool used around the world to work with data," Microsoft explains to teachers who have been living under a rock since 1985. "In these activities, students learn how to use Excel and complete all steps of a mission by engaging in the data science process. In this mission, students analyze key weather data in determining flight safety parameters for a New Shepard rocket and ultimately make a Go/No-Go decision for launch. Students learn how to use Excel while engaging in this dynamic Data Science Process activity [which is not unlike PLATO 'data science' activities of 50 years ago]." Blue Origin last September pledged to inspire youth to pursue space STEM careers as part of the Biden Administration's efforts to increase the space industry's capacity to meet the rising demand for the skilled technical workforce.

Rhode Island representative Jennifer Boylan has submitted legislation that would mandate the inclusion of solar power in all newly constructed single-family dwellings, multi-family dwellings, large commercial buildings, and parking lots exceeding 16,000 sq. ft. From a report: The legislation, titled the Solar Neighborhoods Act (PDF), calls for the Rhode Island Building Code Commission to establish new code requirements for each of the aforementioned construction types. The document specifies that, at a minimum, the Code Commission must add code provisions to address:

- Static load roof strength, requiring that roofs where solar equipment could be placed support a minimum of six pounds per square foot;
- Placement of non-solar-related rooftop equipment, considering positioning that avoids shading solar equipment and maximizes continuous roof space;
- Sizing and provision of extra electrical panels to accommodate the addition of an appropriately-sized future solar energy system; and
- Provision of space for a solar energy system DC-AC inverter in the utility room or on an outside wall.

The legislation also recommends that the Code Commission consider amending the building code to account for roof orientation and angle, roofing materials that minimize or require no roof penetrations, conduit for wiring from roof to electrical panels, and the inclusion of level 2 electric vehicle charging infrastructure. [...] The legislation further requires outdoor parking lots larger than 16,000 sq. ft to install raised solar-panel canopies covering at least 50% of the parking lot's surface, and that 5% of the parking spaces must feature electric vehicle charging stations. Moreover, 20% of parking spaces should be equipped with the infrastructure, such as underground wiring, to accommodate additional EV charging stations in the future. The report notes that California has already implemented a new construction solar mandate, and a similar measure is under consideration in Massachusetts.

An anonymous reader quotes a report from MIT Technology Review: When computer science students and faculty at Carnegie Mellon University's Institute for Software Research returned to campus in the summer of 2020, there was a lot to adjust to. Beyond the inevitable strangeness of being around colleagues again after months of social distancing, the department was also moving into a brand-new building: the 90,000-square-foot, state-of-the-art TCS Hall. The hall's futuristic features included carbon dioxide sensors that automatically pipe in fresh air, a rain garden, a yard for robots and drones, and experimental super-sensing devices called Mites. Mounted in more than 300 locations throughout the building, these light-switch-size devices can measure 12 types of data -- including motion and sound. Mites were embedded on the walls and ceilings of hallways, in conference rooms, and in private offices, all as part of a research project on smart buildings led by CMU professor Yuvraj Agarwal and PhD student Sudershan Boovaraghavan and including another professor, Chris Harrison. "The overall goal of this project," Agarwal explained at an April 2021 town hall meeting for students and faculty, is to "build a safe, secure, and easy-to-use IoT [Internet of Things] infrastructure," referring to a network of sensor-equipped physical objects like smart light bulbs, thermostats, and TVs that can connect to the internet and share information wirelessly.

Not everyone was pleased to find the building full of Mites. Some in the department felt that the project violated their privacy rather than protected it. In particular, students and faculty whose research focused more on the social impacts of technology felt that the device's microphone, infrared sensor, thermometer, and six other sensors, which together could at least sense when a space was occupied, would subject them to experimental surveillance without their consent. "It's not okay to install these by default," says David Widder, a final-year PhD candidate in software engineering, who became one of the department's most vocal voices against Mites. "I don't want to live in a world where one's employer installing networked sensors in your office without asking you first is a model for other organizations to follow." All technology users face similar questions about how and where to draw a personal line when it comes to privacy. But outside of our own homes (and sometimes within them), we increasingly lack autonomy over these decisions. Instead, our privacy is determined by the choices of the people around us. Walking into a friend's house, a retail store, or just down a public street leaves us open to many different types of surveillance over which we have little control. Against a backdrop of skyrocketing workplace surveillance, prolific data collection, increasing cybersecurity risks, rising concerns about privacy and smart technologies, and fraught power dynamics around free speech in academic institutions, Mites became a lightning rod within the Institute for Software Research.

Voices on both sides of the issue were aware that the Mites project could have an impact far beyond TCS Hall. After all, Carnegie Mellon is a top-tier research university in science, technology, and engineering, and how it handles this research may influence how sensors will be deployed elsewhere. "When we do something, companies [and] other universities listen," says Widder. Indeed, the Mites researchers hoped that the process they'd gone through "could actually be a blueprint for smaller universities" looking to do similar research, says Agarwal, an associate professor in computer science who has been developing and testing machine learning for IoT devices for a decade. But the crucial question is what happens if -- or when -- the super-sensors graduate from Carnegie Mellon, are commercialized, and make their way into smart buildings the world over. The conflict is, in essence, an attempt by one of the world's top computer science departments to litigate thorny questions around privacy, anonymity, and consent. But it has deteriorated from an academic discussion into a bitter dispute, complete with accusations of bullying, vandalism, misinformation, and workplace retaliation. As in so many conversations about privacy, the two sides have been talking past each other, with seemingly incompatible conceptions of what privacy means and when consent should be required. Ultimately, if the people whose research sets the agenda for technology choices are unable to come to a consensus on privacy, where does that leave the rest of us?

Virgin Orbit, founded by Richard Branson, filed for Chapter 11 bankruptcy on Tuesday after the satellite launching business struggled to secure long-term funding following a failed launch in January. From a report: The filing comes less than two years after Virgin Orbit first went public at a valuation of roughly $3 billion. But the January mishap left the company scrambling for new funding and forced it to halt operations. "We believe that the Chapter 11 process represents the best path forward to identify and finalize an efficient and value-maximizing sale," Virgin Orbit Chief Executive Dan Hart said in a statement. The company, which was spun off from space tourism firm Virgin Galactic in 2017, sends satellites into orbit using rockets launched from a modified Boeing 747 plane. The Long Beach, California-based company lodged the filing seeking a sale of its assets in a Delaware court days after announcing the layoff of roughly 85% of its 750 employees. Virgin Orbit listed assets of about $243 million and total debt at $153.5 million as of Sept. 30. The company went public in December 2021 through a blank-check merger, raising $255 million less than expected.

Tim Cook's vision for AR and VR hasn't changed. "For almost a decade, Apple's CEO has been banging the drum that AR is more important than VR and that AR is fundamentally about bringing people together," reports The Verge. "And he's still at it." From the report: "If you think about the technology itself with augmented reality, just to take one side of the AR/VR piece, the idea that you could overlay the physical world with things from the digital world could greatly enhance people's communication, people's connection," Cook told GQ's Zach Baron in a long and very interesting profile just published by the magazine. Cook told Baron that he's interested in collaboration; he said something about measuring glass walls; he said his thinking on glasses-as-gadget has changed over the years.

None of this is a product announcement, of course, only the latest in a long string of hints about what Apple sees in this space. Cook's been on this particular line since at least 2016, when he said on Good Morning America that AR "gives the capability for both of us to sit and be very present, talking to each other, but also have other things -- visually -- for both of us to see." [...] At various times over the years, Cook has said AR is a powerful technology for education, that he thinks it'll be as common as "eating three meals a day," and that he thinks AR is as big an idea as the smartphone. But he keeps coming back to the idea that AR should be meant to bring people together in the real world, not keep them apart or transport them to another universe entirely.

Cook also offered what sounds like an explanation for why the headset, which has been heavily rumored over the last couple of years, has taken so long to come out. "I'm not interested in putting together pieces of somebody else's stuff," he told GQ. "Because we want to control the primary technology. Because we know that's how you innovate." Maybe the most revealing thing in the story is the way Cook explains Apple -- or at least explains the way he hopes you'll see Apple. He talks frequently about Apple's environmental commitments, its loud fight against "the data-industrial complex," and the way Apple is trying to help people have better relationships with technology. (Conveniently ignoring that Apple is perhaps more responsible for our phone addictions than any other company, of course.) "Because my philosophy is, if you're looking at the phone more than you're looking in somebody's eyes, you're doing the wrong thing." Apple plans to unveil a mixed-reality headset on June 5th at its annual Worldwide Developers Conference (WWDC).

A Canadian astronaut and three NASA veterans, including one of the world's most experienced female spacewalkers, will fly around the moon next year in the first piloted voyage beyond Earth orbit since the Apollo program ended 50 years ago, the space agency announced Monday. From a report: NASA's Reid Wiseman, Christina Koch and Victor Glover will join Canadian rookie Jeremy Hansen aboard an Orion crew capsule for the Artemis program's second fight, the first carrying a crew bound for the moon. The Artemis 2 mission is intended to pave the way toward the first moon landing -- Artemis 3 -- in the 2025-26 timeframe. Wiseman, Koch and Glover are all veterans of long-duration stays aboard the International Space Station while Hansen will be making his first space flight. Navy Capt. Wiseman, 47, a widowed father of two, is a veteran F/A-18F Super Hornet pilot who holds a master's in systems engineering. He launched aboard a Russian Soyuz spacecraft in 2014 and spent 165 days aboard the space station, then served as chief astronaut after his return to Earth.

Koch, 44, holds a master's in electrical engineering who has experience in Antarctic research. She also launched aboard a Soyuz and spent nearly a full year aboard the lab in 2019-20, venturing outside for six spacewalks, including three all-female excursions. With 42 hours and 15 minutes of EVA time, she ranks third on the list of most experienced female spacewalkers. Glover, 46, is a Navy captain, a father of four and one of only a half dozen African Americans in NASA's astronaut corps. He launched to the station aboard the first operational SpaceX Crew Dragon mission in 2021-22, logging 168 days in orbit. Glover is a veteran test pilot with more than 3,000 hours of flight time and more than 400 carrier landings. Hansen, a 47-year-old colonel in the Canadian armed forces and father of three, is a veteran F-18 fighter pilot. He will be the ninth Canadian to fly in space and the first to venture beyond Earth orbit.

Remember that entrepreneur planning an ostentatious NFT-based restaurant/members-only club in San Francisco? Seven months later it's still "an empty husk of a building, hindered by construction delays and unfulfilled crypto dreams," reports SFGate: Last August, Joshua Sigel held a "groundbreaking" event at what he said would be the future home of Sho Restaurant, located atop Salesforce Park in San Francisco. He told the gathered media that construction of the proposed Japanese fine dining restaurant would begin in less than two months, once some permitting issues were resolved, with a targeted opening date of September or October of 2023.

Sigel maintained that he'd soon be offering 3,275 Sho Club NFT (non-fungible token) memberships — first via a private sale, then a larger public sale in late September — which would serve as the backbone of Sho Restaurant's clientele. (Sigel is the CEO of Sho Group, which encapsulates Sho Restaurant and Sho Club.) There were to be 2,878 "Earth" NFT memberships, priced at $7,500 each; 377 "Water" NFT memberships, priced at $15,000 each; and 20 "Fire" NFT memberships; priced at $300,000 each. The NFTs are basically membership cards for the restaurant, spruced up with Web3 jargon.... Each membership tier comes with increasingly luxurious benefits, though restaurant reservations would also be available for nonmembers.

Seven months later, things don't seem to be going very well for Sho Club or for Sho Restaurant. I recently walked over to Salesforce Park and peered inside the shell of the building that's supposed to become a restaurant; I saw an empty space that looks almost exactly the same as it did in August. The mock-up design photos that journalists looked at during the "groundbreaking" in August remain strewn about on the floor. Permits for Sho Restaurant haven't been issued, the result of Sho Restaurant designers not yet responding to a number of San Francisco Department of Building Inspection notes, among a host of permitting steps that haven't been completed. Sho Club social media accounts have been radio silent since late September....

Sho Club appears to have sold around 100 NFT memberships, rather than 3,275, as Sigel originally projected. I repeatedly reached out to Sigel, to Sho Club, and its public relations representatives. No one replied to my questions.

America's Department of Defense "is gearing up for a future conflict in space," reports the Wall Street Journal, "as China and Russia deploy missiles and lasers that can take out satellites and disrupt military and civilian communications." The White House this month proposed a $30 billion annual budget for the U.S. Space Force, almost $4 billion more than last year and a bigger jump than for other services including the Air Force and the Navy.... A key aim of a stand-alone force was to plan, equip and defend U.S. interests in space for all of the services and focus attention on the emerging threats. For the first time, the spending request also includes plans for simulators and other equipment to train Guardians, as Space Force members are known, for potential battle....

Just as it is on Earth, China is the Pentagon's big worry in space. In unveiling a defense strategy late last year, the Biden administration cast China as the greatest danger to U.S. security. In space, the threats from China range from ground-launched missiles or lasers that could destroy or disable U.S. satellites, to jamming and other cyber interference and attacks in space, said Pentagon officials. China has invested heavily in its space program, with a crewed orbiting station, developing ground-based missiles and lasers as well as more surveillance capabilities. This is part of its broader military aims of denying adversaries access to space-based assets.

China is "testing on-orbit satellite systems which could be weaponized as they have already shown the capability to physically control and move other satellites," Gen. Chance Saltzman, chief of space operations for the U.S. Space Force, told a congressional hearing this month. "There's nothing we can do in space that's of any value if the networks that process the information and data are vulnerable to attack," Gen. Saltzman said. A central part of the Space Force's next tranche of military contracts for rocket launches is protecting them from attacks by China and other adversaries. The hope is to make satellites tougher to approach by adversaries' equipment as well as less susceptible to lasers and jamming from space or the ground, said Space Force leaders.
The article also notes the US Defense Department "is moving away from a small number of school bus-size satellites to a planned constellation of hundreds of smaller ones.

"The larger number of targets makes any one satellite less crucial to the network but also requires changes in the capabilities of the satellites themselves, the rockets that put them into orbit and the communications systems they host."
