Chinese scientists have developed a new method to produce significant quantities of water from lunar soil brought back by the Chang'e-5 mission in 2020, state broadcaster CCTV reported. The "brand-new method" involves heating moon minerals containing hydrogen to generate water vapor, which could be crucial for future lunar research stations and space exploration. Reuters reports: "After three years of in-depth research and repeated verification, a brand-new method of using lunar soil to produce large amounts of water was discovered, which is expected to provide important design basis for the construction of future lunar scientific research stations and space stations," said CCTV. The discovery could have important implications for China's decades-long project of building a permanent lunar outpost amid a U.S.-China race to find and mine the moon's resources.

Using the new method, one tonne of lunar soil will be able to produce about 51-76 kg of water, equivalent to more than a hundred 500ml bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said. China hopes that recent and future lunar expeditions will set the foundations to build the International Lunar Research Station (ILRS), an initiative it is co-leading with Russia.

After a couple of years of regular use, Samsung's $400 Galaxy Ring will end up contributing to the growing e-waste problem. "The Galaxy Ring -- and all smart rings like it -- comes with a huge string attached," writes iFixit in a blog post. "It's 100% disposable, just like the AirPod-style Buds3 that Samsung just released. The culprit? The lithium ion batteries." ZDNet reports: The problem is the battery, and how they have a finite lifespan. Usually that's about 400 recharge cycles, and after that the batteries are finished. And if you can't replace it, then it's the end of the line for the gadget, and it's tossed onto the e-waste pile. [...]

iFixit is damning about this sort of tech. "There's nothing wrong with simple but there is something wrong with unrepairable. Just like the Galaxy Buds3, the Galaxy Ring is a disposable tech accessory that isn't designed to last more than two years." And the bottom line is simple: "We can't recommend buying disposable tech like this." Here's what iFixit's Shahram Mokhtari had to say about the Galaxy Ring's battery, after putting it through a CT scanner: On the right hand side of the ring is the faint outline of a lithium polymer battery pouch. There's an inductive coil sitting right on top of the battery (the lines that look like a rectangular track) and another very similar inductive coil that's parallel and slightly separated from the first. That second inductive coil is inside the charging case and works together with the inductive coil in the ring to recharge the battery inside the Galaxy Ring. Inductive charging is the only practical way to deliver power to a device that doesn't have any ports. But there's something else here that sticks out like a sore thumb ... that is a press connector joining the battery to the rest of the board! This is a surprising use of space, why isn't this directly soldered? Nobody is getting back in there to disconnect this thing!

We love press connectors, they're easy to work with and make replacing batteries a sight easier than desoldering a half dozen wires. But this one is sealed into the device and serves no purpose in replacement or repair. Our best guess as to why it's in the Galaxy Ring: The battery and wireless charging coil were made in one place, the circuit board somewhere else, and it all comes to a production line somewhere where the two need to be connected together quickly and cheaply. Hence the press connector. It's not for your benefit, it's for the manufacturers.

The Wow! signal, detected on August 15, 1977, was an intense radio transmission that appeared artificial and raised the possibility of extraterrestrial contact. However, recent research suggests it may have been caused by a natural astrophysical event involving a magnetar flare striking a hydrogen cloud. Universe Today reports: New research shows that the Wow! Signal has an entirely natural explanation. The research is "Arecibo Wow! I: An Astrophysical Explanation for the Wow! Signal." The lead author is Abel Mendez from the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. It's available at the pre-print server arxiv.org. Arecibo Wow! is a new effort based on an archival study of data from the now-defunct Arecibo Radio Telescope from 2017 to 2020. The observations from Arecibo are similar to those from Big Ear but "are more sensitive, have better temporal resolution, and include polarization measurements," according to the authors. "Our latest observations, made between February and May 2020, have revealed similar narrowband signals near the hydrogen line, though less intense than the original Wow! Signal," said Mendez.

Arecibo detected signals similar to the Wow! signal but with some differences. They're far less intense and come from multiple locations. The authors say these signals are easily explained by an astrophysical phenomenon and that the original Wow! signal is, too. "We hypothesize that the Wow! Signal was caused by sudden brightening from stimulated emission of the hydrogen line due to a strong transient radiation source, such as a magnetar flare or a soft gamma repeater (SGR)," the researchers write. Those events are rare and rely on precise conditions and alignments. They can cause clouds of hydrogen to brighten considerably for seconds or even minutes.

The researchers say that what Big Ear saw in 1977 was the transient brightening of one of several H1 (neutral hydrogen) clouds in the telescope's line of sight. The 1977 signal was similar to what Arecibo saw in many respects. "The only difference between the signals observed in Arecibo and the Wow! Signal is their brightness. It is precisely the similarity between these spectra that suggests a mechanism for the origin of the mysterious signal," the authors write. These signals are rare because the spatial alignment between source, cloud, and observer is rare. The rarity of alignment explains why detections are so rare. The researchers were able to identify the clouds responsible for the signal but not the source. Their results suggest that the source is much more distant than the clouds that produce the hydrogen signal. "Given the detectability of the clouds as demonstrated in our data, this insight could enable precise location of the signal's origin and permit continuous monitoring for subsequent events," the researchers explain.

An anonymous reader quotes a report from The Guardian, written by Julian Benson: It's been eight years since Civilization 6 -- the most recent in a very long-running strategy game series that sees you take a nation from the prehistoric settlement of their first town through centuries of development until they reach the space age. Since 2016 it has amassed an abundance of expansions, scenario packs, new nations, modes and systems for players to master -- but series producer Dennis Shirk at Firaxis Games feels that enough it enough. "It was getting too big for its britches," he says. "It was time to make something new."

"It's tough to even get through the whole game," designer Ed Beach says, singling out the key problem that Firaxis aims to solve with the forthcoming Civilization 7. While the early turns of a campaign in Civilization 6 can be swift, when you're only deciding the actions for the population of a single town, "the number of systems, units, and entities you must manage explodes after a while," Beach says. From turn one to victory, a single campaign can take more than 20 hours, and if you start falling behind other nations, it can be tempting to restart long before you see the endgame. That's why Civilization 7's campaign has been split into three ages -- Antiquity, Exploration and Modern -- with each ending in a dramatic explosion of global crises. "Breaking the game into chapters lets people get through history in a more digestible fashion," Beach says.

When you start a new campaign, you pick a leader and civilization to govern, and direct your people in establishing their first settlements and encounters with the other peoples populating a largely undeveloped land. You'll choose the technologies they research, the expansions they make to their cities, and whom they try to befriend or conquer. Every turn you complete or scientific, economic, cultural and military milestone you pass adds points to a meter running in the background. Once that meter hits 200, you and all the other surviving civilizations on the map will transition into the next age. When moving from Antiquity to Exploration and later Exploration to Modern, you select a new civilization to lead. You'll retain all the cities you controlled before but have access to different technologies and attributes. This may seem strange, but it's built to reflect history: think of London, which was once run by the Romans before being supplanted by the Anglo-Saxons. No empire lasts for ever, but they don't all collapse, either.

Breaking Civilization 7 into chapters also gives campaigns a new rhythm. As you approach the end of an age, you'll begin to face global crises. In Antiquity, for instance, you can see a proliferation of independent powers similar to the tribes that tore down Rome. "We're not calling them barbarians any more," Beach says. "It's a more nuanced way to present them." These crises multiply and strengthen until you reach the next age. "It's like a sci-fi or fantasy series with a huge, crazy conclusion, and then the next book starts nice and calm," Beach says. "There's a point where getting to the next age is a relief." Here's a round-up of thoughts on Civilization 7 from some of the most respected gaming outlets and reviewers:

North America's eight primary data center markets added 515 megawatts (MW) of new supply in the first half of 2024 -- the equivalent of Silicon Valley's entire existing inventory -- according to a new report real-estate services firm CBRE. From a report: All of Silicon Valley has 459 MW of data center supply, while those main markets have a total of 5,689 MW. That's up 10% from a year ago and about double what it was five years ago. Data center space under construction is up nearly 70% from a year ago and is currently at a record high. But the vast majority of that is already leased, and vacancy rates have shrunk to a record low of 2.8%. In other words, developers are building an insane amount of data center capacity, but it's still not enough to meet the growing demands of cloud computing and artificial intelligence providers.

NASA astronauts Butch Wilmore and Suni Williams are facing challenges returning to Earth due to compatibility issues between their Boeing-designed spacesuits and SpaceX's Dragon spacecraft. Inc. Magazine reports: The space suits in question are the "intra-vehicular activity" outfits now worn by astronauts. They're simpler than the bulky extra-vehicular space suits used on space walks, and are designed to keep astronauts safe in the capsule in the very unlikely case there's a problem that causes the capsule's atmosphere to be lost. The problem is simple: Should Butch and Suni need to fly back aboard SpaceX's vehicle, their suits won't fit in Dragon's seats. [...]

Boeing and SpaceX suits evolved under totally different design sensibilities. If Boeing and NASA deem Starliner unsafe for humans to fly home in, Butch and Suni must head earthward aboard a SpaceX Dragon, but their suits won't be able to plug into Dragon's systems. Like trying to plug an essentially outdated USB A socket into an iPhone's charge port, the suit connectors have different shapes, styles, and functions. The suits themselves have different systems that integrate with their own capsules for purposes like air leak checks during pre-flight testing.

So if an emergency situation presents itself and astronauts have to come back to Earth before proper plans are finalized, Butch and Suni will have to return inside the cargo section of a Dragon space capsule "unsuited," according to NASA leadership who spoke on the matter in a press conference last week. Other plans include flying up suitable Dragon-connecting space suits for the two astronauts on a later mission, should Starliner be deemed incapable of bringing them back.

Bloomberg's Mark Gruman remembers how Apple's hardware group "allowed Apple to dump Intel chips from its entire Mac lineup."

And they're now building an in-house cellular modem: For more than a decade, Apple has used modem chips designed by Qualcomm... But in 2018 — while facing a legal battle over royalties and patents — Apple started work on its own modem design.... It's devoting billions of dollars, thousands of engineers and millions of working hours to a project that won't really improve its devices — at least at the outset...

Over the past few years, Apple's modem project has suffered numerous setbacks. There have been problems with performance and overheating, and Apple has been forced to push back the modem's debut until next year at the earliest. The rollout will take place on a gradual basis — starting with niche models — and take a few years to complete. In a sign of this slow transition, Apple extended its supplier agreement with Qualcomm through March 2027... But Qualcomm has said that Apple will still have to pay it some royalties regardless (the chipmaker believes that Apple won't be able to avoid infringing its patents).

So it's hard to tell how big the benefits will be in the near term. Down the road, there are plans for Apple to fold its modem design into a new wireless chip that handles Wi-Fi and Bluetooth access. That would create a single connectivity component, potentially improving reliability and battery life. There's also the possibility that Apple could one day combine all of this into the device's main system on a chip, or SoC. That could further cut costs and save space inside the iPhone, allowing for more design choices. Furthermore, if Apple does ultimately save money by switching away from Qualcomm, it could redirect that spending toward new features and components.

"From the beginning, we have believed that the right way to build these AI models is with open licenses," says the Open Model Initiative. SD Times quotes them as saying that open licenses "allow creatives and businesses to build on each other's work, facilitate research, and create new products and services without restrictive licensing constraints."

Phoronix explains the community initiative "came about over the summer to help advance open-source AI models while now is becoming part of the Linux Foundation to further their cause." As part of the Linux Foundation, the OMI will be working to establish a governance framework and working groups, create shared standards to enhance model interoperability and metadata practices, develop a transparent dataset for training and captioning, complete an alpha test model for targeted red teaming, and release an alpha version of a new model with fine-tuning scripts before the end of 2024.
The group was established "in response to a number of recent decisions by creators of popular open-source models to alter their licensing terms," reports Silicon Angle: The creators highlighted the recent licensing change announced by Stability AI Ltd., regarding its popular image-generation model Stable Diffusion 3 (SD3). That model had previously been entirely free and open, but the changes introduced a monthly fee structure and imposed limitations on its usage. Stability AI was also criticized for the lack of clarity around its licensing terms, but it isn't the only company to have introduced licensing restrictions on previously free software. The OMI intends to eliminate all barriers to enterprise adoption by focusing on training and developing AI models with "irrevocable open licenses without deletion clauses or recurring costs for access," the Linux Foundation said.
InfoWorld also notes "the unavailability of source code and the license restrictions from LLM providers such as Meta, Mistral and Anthropic, who put caveats in the usage policies of their 'open source' models." Meta, for instance, does provide the rights to use Llama models royalty free without any license, but does not provide the source code, according to [strategic research firm] Everest Group's AI practice leader Suseel Menon. "Meta also adds a clause: 'If, on the Meta Llama 3, monthly active users of the products or services is greater than 700 million monthly active users, you must request a license from Meta.' This clause, combined with the unavailability of the source code, raises the question if the term open source should apply to Llama's family of models," Menon explained....

The OMI's objectives and vision received mixed reactions from analysts. While Amalgam Insights' chief analyst Hyoun Park believes that the OMI will lead to the development of more predictable and consistent standards for open source models, so that these models can potentially work with each other more easily, Everest Group's Malik believes that the OMI may not be able to stand before the might of vendors such as Meta and Anthropic. "Developing LLMs is highly compute intensive and has cost big tech giants and start-ups billions in capital expenditure to achieve the scale they currently have with their open-source and proprietary LLMs," Malik said, adding that this could be a major challenge for community-based LLMs.

The AI practice leader also pointed out that previous attempts at a community-based LLM have not garnered much adoption, as models developed by larger entities tend to perform better on most metrics... However, Malik said that the OMI might be able to find appropriate niches within the content development space (2D/3D image generation, adaptation, visual design, editing, etc.) as it begins to build its models... One of the other use cases for the OMI's community LLMs is to see their use as small language models (SLMs), which can offer specific functionality at high effectiveness or functionality that is restricted to unique applications or use cases, analysts said. Currently, the OMI's GitHub page has three repositories, all under the Apache 2.0 license.

"A new front has opened in the longstanding debate over how fast the universe is expanding," writes Science magazine: For years astronomers have argued over a gulf between the expansion rate as measured from galaxies in the local universe and as calculated from studies of the cosmic microwave background (CMB), the afterglow of the Big Bang. The disparity was so large and persistent that some astronomers thought the standard theory of the universe might have to be tweaked. But over the past week, results from NASA's new James Webb Space Telescope orbiting observatory suggest the problem may be more mundane: some systematic error in the strategies used to measure the distance to nearby galaxies.

"The evidence based on these data does not suggest the need for additional physics," says Wendy Freedman of the University of Chicago, who leads [the Carnegie-Chicago Hubble Program, or CCHP] that calculated the expansion rate from JWST data using three different galactic distance measurements and released the results on the arXiv preprint server. (The papers have not yet been peer reviewed.) The methods disagreed about the expansion rate, known as the Hubble constant, or H0, and two were close to the CMB prediction.
Specifically, the team used JWST to measure the distance to 10 local galaxies using three stars with a predictable brightness: Cepheids, the brightest red giant stars, and carbon stars. Science notes that the last two methods "agreed to about 1%, but differed from the Cepheid-based distance by 2.5% to 4%." Combining all three methods the team derived a value "just shy of 70 km/s per Mpc," according to the article — leading the University of Chicago's Freedman to say "There's something systematic in the measurements. Until we can establish unambiguously where the issue lies in the nearby universe, we can't be claiming that there's additional physics in the distant universe."

But the controversy continues, according to Adam Riess of Johns Hopkins University (leader of a team of Hubble Constant researchers known as SH0ES). Riess points out that other teams have used JWST to measure distances with all three methods separately and have come up with values closer to the original SH0ES result. He also questions why CCHP excluded data from telescopes other than JWST. "I don't see a compelling justification for excluding the data they do," he says.

Citizen scientists from NASA's Backyard Worlds: Planet 9 project discovered a hypervelocity object, CWISE J1249, moving fast enough to escape the Milky Way. "This hypervelocity object is the first such object found with the mass similar to or less than that of a small star," reports NASA's Science Editorial Team, suggesting the object may have originated from a binary star system or a globular cluster. From the report: A few years ago, longtime Backyard Worlds citizen scientists Martin Kabatnik, Thomas P. Bickle, and Dan Caselden spotted a faint, fast-moving object called CWISE J124909.08+362116.0, marching across their screens in the WISE images. Follow-up observations with several ground-based telescopes helped scientists confirm the discovery and characterize the object. These citizen scientists are now co-authors on the team's study about this discovery published in the Astrophysical Journal Letters (a pre-print version is available here). CWISE J1249 is zooming out of the Milky Way at about 1 million miles per hour. But it also stands out for its low mass, which makes it difficult to classify as a celestial object. It could be a low-mass star, or if it doesn't steadily fuse hydrogen in its core, it would be considered a brown dwarf, putting it somewhere between a gas giant planet and a star.

Ordinary brown dwarfs are not that rare. Backyard Worlds: Planet 9 volunteers have discovered more than 4,000 of them! But none of the others are known to be on their way out of the galaxy. This new object has yet another unique property. Data obtained with the W. M. Keck Observatory in Maunakea, Hawaii, show that it has much less iron and other metals than other stars and brown dwarfs. This unusual composition suggests that CWISE J1249 is quite old, likely from one of the first generations of stars in our galaxy. Why does this object move at such high speed? One hypothesis is that CWISE J1249 originally came from a binary system with a white dwarf, which exploded as a supernova when it pulled off too much material from its companion. Another possibility is that it came from a tightly bound cluster of stars called a globular cluster, and a chance meeting with a pair of black holes sent it soaring away.

NASA chief Bill Nelson didn't mince words about the agency's budget crunch. "You can't put 10 pounds of potatoes in a five-pound sack," he told ArsTechnica in an interview, addressing $4.7 billion in cuts over two years.

To scientists fretting over axed missions, Nelson offered a frank "I feel your pain." The Mars Sample Return's ballooning $11 billion price tag and 2040 timeline forced a reset. "We pulled the plug," Nelson admitted, but he's banking on cheaper, creative alternatives emerging by year's end.

The moon rover Viper got the chop too, blowing its budget by 40%. "There comes a limit," Nelson said, defending the tough call. Viper lunar rover project was "running 40 percent over budget." He defended these decisions as necessary given the $2 billion cut to science funding alone. The cuts stem from the Fiscal Responsibility Act. Nelson expressed hope for a "reprieve" in fiscal year 2026, but noted uncertainty due to another looming debt ceiling issue.

AT&T and Verizon are urging the FCC to reject SpaceX's plan to offer cellular service with T-Mobile, arguing that it would cause harmful interference to terrestrial mobile networks. Ars Technica reports: Filings urging the Federal Communications Commission to deny SpaceX's request for a waiver were submitted by AT&T and Verizon this week. The plan by SpaceX's Starlink division also faces opposition from satellite companies EchoStar (which owns Dish and Hughes) and Omnispace. SpaceX and T-Mobile plan to offer Supplemental Coverage from Space (SCS) for T-Mobile's cellular network using SpaceX satellites. As part of that plan, SpaceX is seeking a waiver of FCC rules regarding out-of-band emission limits.

AT&T's petition to deny the SpaceX waiver request said the FCC's "recent SCS order appropriately recognized that SCS deployments should not present any risk to the vital terrestrial mobile broadband networks upon which millions of Americans rely today. The Commission authorized SCS as secondary to terrestrial mobile service, correctly explaining that the SCS framework must 'retain service quality of terrestrial networks, protect spectrum usage rights, and minimize the risk of harmful interference.'" AT&T said SpaceX's requested "ninefold increase" to the allowable power flux-density limits for out-of-band emissions "would cause unacceptable harmful interference to incumbent terrestrial mobile operations. Specifically, AT&T's technical analysis shows that SpaceX's proposal would cause an 18% average reduction in network downlink throughput in an operational and representative AT&T PCS C Block market deployment." Verizon's opposition to the waiver request similarly said that SpaceX's proposal "would subject incumbent, primary terrestrial licensee operations in adjacent bands to harmful interference." Wireless phone performance will suffer, Verizon said [...]. SpaceX and T-Mobile told FCC staff that their plan will not harm other wireless operations and predicted that competitors will make misleading claims. SpaceX also argued that the FCC's emissions limit is too strict and should be changed.

An anonymous reader quotes a report from Ars Technica: SpaceX will fly the first-ever human spaceflight over the Earth's poles, possibly before the end of this year, the company announced Monday. The private Crew Dragon mission will be led by a Chinese-born cryptocurrency entrepreneur named Chun Wang, and he will be joined by a polar explorer, a roboticist, and a filmmaker whom he has befriended in recent years. The "Fram2" mission, named after the Norwegian research ship Fram, will launch into a polar corridor from SpaceX's launch facilities in Florida and fly directly over the north and south poles. The three-to-five day mission is being timed to fly over Antarctica near the summer solstice in the Southern Hemisphere, to afford maximum lighting.

The four-person crew will fly, fittingly, aboard Crew Dragon Endurance, which is named after Ernest Shackleton's famous ship that was trapped in the Antarctic ice and eventually sunk there about a century ago. The spacecraft will be fitted with a cupola for both photography and filming. This will be SpaceX's third free-flying mission aboard Crew Dragon, following the Inspiration4 mission funded and commanded by US entrepreneur Jared Isaacman in 2021, and his forthcoming Polaris Dawn mission which may launch later this month. In an interview, Wang said he modeled the Fram2 mission's crew and public outreach programs on the template established by Isaacman.

sciencehabit shares a report from Science.org: For years, astronomers thought it was the Milky Way's destiny to collide with its near neighbor the Andromeda galaxy a few billion years from now. But a new simulation finds a 50% chance the impending crunch will end up a near-miss, at least for the next 10 billion years. It's been known that Andromeda is heading toward our home Galaxy since 1912, heading pretty much straight at the Milky Way at a speed of 110 kilometers per second. Such galaxy mergers, which can be seen in progress elsewhere in the universe, are spectacularly messy affairs. Although most stars survive unscathed, the galaxies' spiral structures are obliterated, sending streams of stars spinning off into space. After billions of years, the merged galaxies typically settle into a single elliptical galaxy: a giant featureless blob of stars. A study from 2008 suggested a Milky Way-Andromeda merger was inevitable within the next 5 billion years, and that in the process the Sun and Earth would get gravitationally grabbed by Andromeda for a time before ending up in the distant outer suburbs of the resulting elliptical, which the researchers dub "Milkomeda."

In the new simulation, researchers made use of the most recent and best estimates of the motion and mass of the four largest galaxies in the Local Group. They then plugged those into simulations developed by the Institute for Computational Cosmology at Durham University. First, they ran the simulation including just the Milky Way and Andromeda and found that they merged in slightly less than half of the cases -- lower odds than other recent estimates. When they included the effect of the Triangulum galaxy, the Local Group's third largest, the merger probability increased to about two-thirds. But with the inclusion of the Large Magellanic Cloud, a satellite galaxy of the Milky Way that is the fourth largest in the Local Group, those chances dropped back down to a coin flip. And if the cosmic smashup does happen, it won't be for about 8 billion years. "As it stands, proclamations of the impending demise of our Galaxy appear greatly exaggerated," the researchers write. Meanwhile, if the accelerating expansion of the universe continues unabated, all other galaxies will disappear beyond our cosmic event horizon, leaving Milkomeda as the sole occupant of the visible universe. The study is available as a preprint on arXiv.

The New York Times visits the downtown of one of America's biggest tech cities to explore San Francisco's "Vacant to Vibrant" initiative, where "city and business leaders provide free rent for up to six months" to "entrepreneurs who want to set up shop in empty spaces, many of which are on the ground floor of office buildings."

The program also offers funding for business expenses (plus technical and business permit assistance) — and it seems to be working. One cafe went on to sign a five-year lease for a space in the financial district's iconic One Embarcadero Center building — and the building's landlord says the program also resulted in another three long leases. Can the progress continue? The hope is that these pop-up operations will pay rent and sign longer leases after the free-rent period is over, and that their presence will regenerate foot traffic in the area. Some 850 entrepreneurs initially applied for a slot, and 17 businesses were chosen to occupy nine storefront spaces in the fall. Out of those businesses, seven extended their leases and now pay rent. Eleven businesses were selected in May for the program's second cohort, which started operating their storefronts this summer...

The city's office vacancy rate hit 33.7%, a record high, in the second quarter this year, according to JLL, a commercial real estate brokerage. That's one of the bleakest office markets in the nation, which has an average vacancy rate of about 22%. For the moment, however, San Francisco has a silver lining in Vacant to Vibrant. Rod Diehl, the BXP executive vice president who oversees its West Coast properties, said the pop-up strategy was good not just for local business owners to test their concepts and explore growth opportunities, but also for office leasing efforts... Beyond free rent, which is typically given for three months with a possibility for another three months, Vacant to Vibrant provides up to $12,000 to the businesses to help cover insurance and other expenses. The program also offers grants up to $5,000 for building owners to cover costs for tenant improvements in the spaces as well as for other expenses like utilities...

In addition to the Vacant to Vibrant program — which received $1 million from the city initially and is set to receive another $1 million for the current fiscal year, which began July 1 — the city is directing nearly $2 million toward a similar pop-up program. This new program would help businesses occupy larger empty spaces along Powell Street, as crime and other retail pressures have driven out several retailers, including Anthropologie, Banana Republic and Crate & Barrel, in the Union Square area.
One business owner who joined "Vacant to Vibrant" in May says they haven't decided yet whether to sign a lease. "It's not as crowded as before the pandemic." But according to the article, "she was hopeful that more businesses opening nearby would attract more people."

"In addition to filling empty storefronts, the program has the opportunity to bring in a fresher and more localized downtown shopping vibe, said Laurel Arvanitidis, director for business development at San Francisco's Office of Economic and Workplace Development." Victor Gonzalez, an entrepreneur who founded GCS Agency to stage showings for artists, is embracing the opportunity to get a foothold downtown despite the city's challenges. When he opened a storefront as part of the first Vacant to Vibrant cohort in the Financial District last year, he immediately knew that he wanted to stay there as long as possible. He has since signed a three-year lease. "San Francisco is no stranger to big booms and busts," he said. "So if we're in the midst of a bust, what's next? It's a boom. And I want to be positioned to be part of it."

"AT&T has been told to stop running ads that claim the carrier is already offering cellular coverage from space," reports Ars Technica: AT&T intends to offer Supplemental Coverage from Space (SCS) and has a deal with AST SpaceMobile, a Starlink competitor that plans a smartphone service from low-Earth-orbit satellites. But AST SpaceMobile's first batch of five satellites isn't scheduled to launch until September.

T-Mobile was annoyed by AT&T running an ad indicating that its satellite-to-cellular service was already available, and filed a challenge with the advertising industry's self-regulatory system run by BBB National Programs. The BBB National Advertising Division (NAD) ruled against AT&T last month and the carrier appealed to the National Advertising Review Board (NARB), which has now also ruled against AT&T...

AT&T, which is also famous for renaming its 4G service "5GE," reluctantly agreed to comply with the recommendation and released a new version of the satellite-calling commercial with more specific disclaimers.
The 30-second ad — titled "Epic Bad Golf Day" — featured Ben Stiller golfing chasing a badly-hit golf ball all the way into the desert (accompanied by the Pixies' song "Where is My Mind").

But according to the article, T-Mobile filed an official complaint with the advertising review board that "the use of humor does not shield an advertiser from its obligation to ensure that claims are truthful and non-misleading." The ad originally included small text that described the depicted satellite call as a "demonstration of evolving technology." The text was changed this week to say that "satellite calling is not currently available...."

The original version also had text that said, "the future of help is an AT&T satellite call away." The NARB concluded that this "statement can be interpreted reasonably as stating that 'future' technology has now arrived... In the updated version of the ad, AT&T changed the text to say that "the future of help will be an AT&T satellite call away."

An anonymous reader shared this report from the Observer: Thousands of scientists have protested to the US Congress over the "unprecedented and indefensible" decision by Nasa to cancel its Viper lunar rover mission. In an open letter to Capitol Hill, they have denounced the move, which was revealed last month, and heavily criticised the space agency over a decision that has shocked astronomers and astrophysicists across the globe.

The car-sized rover has already been constructed at a cost of $450 million and was scheduled to be sent to the moon next year, when it would have used a one-metre drill to prospect for ice below the lunar surface in soil at the moon's south pole. Ice is considered to be vital to plans to build a lunar colony, not just to supply astronauts with water but also to provide them with hydrogen and oxygen that could be used as fuels... "Quite frankly, the agency's decision beggars belief," said Prof Clive Neal, a lunar scientist at the University of Notre Dame, in Indiana. "Viper is a fundamental mission on so many fronts and its cancellation basically undermines Nasa's entire lunar exploration programme for the next decade. It is as straightforward as that. Cancelling Viper makes no sense whatsoever."

This view was backed by Ben Fernando of Johns Hopkins University, who was one of the organisers of the open letter to Congress. "A team of 500 people dedicated years of their careers to construct Viper and now it has been cancelled for no good reason whatsoever," he told the Observer last week. "Fortunately I think Congress is taking this issue very seriously and they have the power to tell Nasa that it has to go ahead with the project. Hopefully they will intervene."
"When Nasa announced its decision to abandon Viper, the space agency said it planned to disassemble and reuse its components for other moon missions — unless other space companies or agencies offered to take over the project. More than a dozen groups have since expressed an interest in taking over Viper, a Nasa spokesperson told the Observer last week."

FBI agent Rick Smith remembered seeing that Austrian-born Silicon Valley entrepreneur one year earlier — walking into San Francisco's Soviet Consulate in the early 1980s. Their chance reunion at a bar "would sow the seeds for a major counterintelligence campaign," writes a national security journalist in Politico, describing the collaboration as "an FBI-led operation that sold the Soviet Bloc millions in secretly sabotaged U.S. hi-tech."

The Austrian was already selling American tech goods to European countries, and "By the early 1980s, the FBI knew the Soviet Union was desperate for cutting-edge American technology, like the U.S.-produced microchips then revolutionizing a vast array of digital devices, including military systems..." Moscow's spies worked assiduously to steal such dual use tech or purchase it covertly. The Soviet Union's ballistic missile programs, air defense systems, electronic spying platforms, and even space shuttles, depended on it.... But such tech-focused sanctions-evasion schemes by America's foes offer opportunities for U.S. intelligence, too — including the opportunity to launch ultra-secret sabotage campaigns to alter sensitive technologies before they reach their final destination... Working under the FBI's direction, the Austrian agreed to pose as a crook, a man willing to sell prohibited technology to the communist Eastern Bloc... [T]he FBI and the Austrian would seed faulty tech to Moscow and its allies; drain the Soviet Bloc's coffers; expose its intelligence officers and secret American conspirators; and reveal to American counterspies exactly what tech the Soviets were after...

[T]he Soviet Bloc would unknowingly purchase millions of dollars' worth of sabotaged U.S. goods. Communist spies, ignorant that they were being played, would be feted with a literal parade in a Warsaw Pact capital for their success in purchasing this forbidden technology from the West... The Austrian's connections now presented a major opportunity. The Bulgarians, and their East German and Russia allies, were going to get that forbidden tech. But not before the FBI tampered with it first...

Some of the tech was subtly altered before the Bulgarians could get their hands on it. Some was rendered completely unusable. Some of it was shipped unadulterated to keep the operation humming — and allay any suspicions from the Eastern Bloc about what might be going on. And some of it never made its way to the Bulgarians at all. In one case, the bureau intercepted a $400,000 order of computer hardware from the San Jose-based firm Proquip and shipped out 6,000 pounds of sandbags instead.... Some suffered what appeared to be "accidental" wear-and-tear during the long journey to the Eastern Bloc, recalled Ed Appel [a former senior FBI official]. Other times, the FBI would tamper with the electronics so they would experience "chance" voltage overloads once Soviet Bloc operatives plugged them in. The sabotage could also be more subtle, designed to degrade machine parts or microchips over time, or to render hi-tech tools that required intense precision slightly, if imperceptibly, inaccurate.
The article concludes that "While the Soviet Union might have imploded over three decades ago... Russia's intelligence services are still scouring the globe for prohibited U.S. tech, particularly since Moscow's February 2022 invasion of Ukraine...

"Russia has reportedly even covertly imported household items like refrigerators and washing machines to rip out the microchips within them for use in military equipment."

Google's loss in an antitrust trial is just the beginning. According to Yahoo Finance's senior legal reporter, Google now also has to defend itself "against another perilous antitrust challenge that could inflict more damage." Starting in September, the tech giant will square off against federal prosecutors and a group of states claiming that Google abused its dominance of search advertising technology that is used to sell, buy, and broker advertising space online... Juggling simultaneous defenses "will definitely create a strain on its resources, productivity, and most importantly, attention at the most senior levels," said David Olson, associate professor at Boston College Law School.... The two cases targeting Google have the potential to inflict major damage to an empire amassed over the last two decades.

The second case that begins next month began with a lawsuit filed in the US District Court for the Eastern District of Virginia by the Justice Department and eight states in December 2020... Prosecutors allege that since at least 2015 Google has thwarted meaningful competition and deterred innovation through its ownership of the entities and software that power the online advertising technology market. Google owns most of the technology to buy, sell, and serve advertisements online... Google's share of the US and global advertising markets — when measured either by revenue or impressions — exceeded 90% for "many years," according to the complaint.

The government prosecutors accused Google of siphoning off $0.35 of each advertising dollar that flowed through its ad tech tools.
