Google announced updates to its search ranking systems aimed at promoting high-quality content and demoting manipulative or low-effort material, including content generated by AI solely to summarize other sources. The company also stated it is improving its ability to detect and combat tactics used to deceive its ranking algorithms.

The world's biggest builder of recycling plants has teamed with a startup to install AI-powered systems for sorting recycling, reports the Washington Post. And now over the next few years, "The companies plan to retrofit thousands of recycling facilities around the world with computers that can analyze and identify every item that passes through a waste plant, they said Wednesday." "[S]orted" recyclables, particularly plastic, wind up contaminated with other forms of trash, according to Lokendra Pal, a professor of sustainable materials engineering at North Carolina State University... [W]aste plants don't catch everything. [AI startup] Greyparrot has already installed over 100 of its AI trash spotters in about 50 sorting facilities around the world, and [co-founder Ambarish] Mitra said as much as 30 percent of potentially recyclable material winds up getting lumped in with the trash that's headed for the landfill. Failing to recycle means companies have to make more things from scratch, including a lot of plastic from fossil fuels. Also, more waste ends up in landfills and incinerators, which belch greenhouse gases into the atmosphere and pollute their surroundings.

Mitra said putting Greyparrot's AI tools in thousands of waste plants around the world can raise the percentage of glass, plastic, metal and paper that makes it to recycling facilities. "If we can move the needle by even 5 to 10 percent, that would be a phenomenal outcome on a planetary basis for greenhouse gas emissions and environmental impact," he said. Cutting contamination would make recycled materials more valuable and raise the chances that companies would use them to make new products, according to Reck. "If the AI and the robots potentially helped to increase the quality of the recycling stream, that's huge," she said...

Greyparrot's device is, basically, a set of visual and infrared cameras hooked up to a computer, which monitors trash as it passes by on a conveyor belt and labels it under 70 categories, from loose bottle caps (not recyclable!) to books (sometimes recyclable!) to aluminum cans (recyclable!). Waste plants could connect these AI systems to sorting robots to help them separate trash from recyclables more accurately. They could also use the AI as a quality control system to measure how well they're sorting trash from recyclables. That could help plant managers tinker with their assembly lines to recover more recyclables, or verify that a bundle of recyclables is free of contaminants, which would allow them to sell for a higher price.
GreyParrot's co-founder said their trash-spotting computers "could one day help regulators crack down on companies that produce tsunamis of non-recyclable packaging," according to the article.

"The AI systems are so accurate, he said, that they can identify the brands on individual items. 'There could be insights that make them more accountable for ... the commitments they made to the public or to shareholders,' he said."

The Linux Foundation's own "Open Software Security foundation" has an associated project called Alpha-Omega funded by Microsoft, Google, and Amazon with a mission to catalyze sustainable security improvements to critical open source projects and ecosystems.

It was established nearly two years ago in February of 2022 — and this month announced plans to continue supporting the Rust Foundation Security Initiative: 2022 was also the first full year of operation for the Rust Foundation — an independent nonprofit dedicated to stewarding the Rust programming language and supporting its global community. Given the considerable growth and rising popularity of the Rust programming language in recent years, it has never been more critical to have a healthy and well-funded foundation in place to help ensure the safety and security of this important language.

When the Rust Foundation emerged, OpenSSF recognized a shared vision of global open source security baked into their organizational priorities from day one. These shared security values were the driving force behind Alpha-Omega's decision to grant $460k USD to the Rust Foundation in 2022. This funding helped underwrite their Security Initiative — a program dedicated to improving the state of security within the Rust programming language ecosystem and sowing security best practices within the Rust community. The Security Initiative began in earnest this past January and has now been in operation for a full year with many achievements to note and exciting plans in development.

While security is a clear priority of the Rust language itself and can be seen in its memory safety-critical features, the Rust Project cannot reasonably be expected to foster long term, sustainable security without proper support and funding. Indeed, there is still a pervasive attitude across technology that cybersecurity is being managed and prioritized by "someone else." The unfortunate impact of this attitude is that critical security work often falls on overburdened and under-resourced open source maintainers. By prioritizing the Security Initiative during their first full year in operation, the Rust Foundation has taken on the responsibility of overseeing — and supporting — security improvements within the Rust ecosystem while ensuring meaningful progress...

Alpha-Omega is excited to announce our second year of supporting the Rust Foundation Security Initiative. We believe that this funding will build on the good work and momentum established by the Rust Foundation in 2023. Through this partnership, we are helping relieve maintainer burdens while paving an important path towards a healthier and more secure future within the Rust ecosystem.
Meanwhile, this month the Rust Foundation announced that downloads from Rust's package repository crates.io have now reached 45 billion — and that the foundation is "committed to facilitating the healthy growth of Rust through funding and resources for the community and the Project.

"After conducting initial planning and research and getting approval from our board of directors, we are pleased to announce our intention to help fulfill this commitment by developing a Rust Foundation training and certification program." We continue to be supportive of anyone creating Rust training and education materials. In fact, we are proud to have provided funding to a few individuals involved in this work via our Community Grants Program. Our team is also aware that commercial Rust training courses already exist and that global training entities are already developing their own Rust-focused programs. Given the value of Rust in professional open source, this makes sense. However, we are eager to introduce a program that will allow us to direct profits back into the Rust ecosystem.

As a nonprofit organization, we sit in a unique position thanks to the tools, connections, insights, administrative support, and resources at our disposal — all of which will add value to course material aimed at professional development and adoption. We see our forthcoming program as one tool of many that can be used to verify skills for prospective employers, and for those employers to build out their professional teams of Rust expertise. We will remain supportive of existing training programs offered by Rust Foundation member companies and we'll look for ways to ensure this remains the case as program development progresses... There is no set launch date for the Rust Foundation training and certification program yet, but we plan to continue laying high-quality groundwork in Q4 of 2023 and the first half of 2024.

An anonymous reader quotes a report from CBS News: Denmark's Lego said on Monday that it remains committed to its quest to find sustainable materials to reduce carbon emissions, even after an experiment by the world's largest toymaker to use recycled bottles did not work. Lego said it has "decided not to progress" with making its trademark colorful bricks from recycled plastic bottles made of polyethylene terephthalate, known as PET, and after more than two years of testing "found the material didn't reduce carbon emissions." Lego enthusiastically announced in 2021 that the prototype PET blocks had become the first recycled alternative to pass its "strict" quality, safety and play requirements, following experimentation with several other iterations that proved not durable enough.

The company said scientists and engineers tested more than 250 variations of PET materials, as well as hundreds of other plastic formulations, before nailing down the prototype, which was made with plastic sourced from suppliers in the U.S. that were approved by the Food and Drug Administration and European Food Safety Authority. On average, a one-liter plastic PET bottle made enough raw material for ten 2 x 4 Lego bricks. Despite the determination that the PET prototype failed to save on carbon emissions, Lego said it remained "fully committed to making Lego bricks from sustainable materials by 2032." [...] Lego said it will continue to use bio-polypropylene, the sustainable and biological variant of polyethylene -- a plastic used in everything from consumer and food packaging to tires -- for parts in Lego sets such as leaves, trees and other accessories.

Amazon.com has introduced a generative AI service that it claims will "dramatically improve the listing creation and management experience for sellers." The company says the AI "will simplify how Amazon sellers create more thorough and captivating product descriptions" and "enrich existing listings, helping customers more confidently make purchase decisions." The Register reports: Using an unspecified large language model, Amazon will allow sellers to enter "a brief description of the product in a few words or sentences" and then "generate high-quality content for their review." Sellers can review the AI output, or just "directly submit the automatically generated content to the Amazon catalog." Amazon reckons the results will offer customers "more complete, consistent, and engaging product information that will enhance their shopping experiences."

Authors who post their works to the e-tail elephant's Kindle bookstore also need to consider AI as last week the content guidelines for e-book authors and publishers added a requirement to disclose machine-generated content "when you publish a new book or make edits to and republish an existing book." Amazon wants to be told of any AI-generated images, texts, or translations. Altering the work of an AI does not exempt authors and publishers from this requirement, as Amazon's definition of "AI-generated" includes material generated by a machine that received "substantial edits" by a human. AI-assisted content -- defined as material created by a human and then offered to a machine for edits, refinements, error-checks or other improvements -- doesn't have to be disclosed.

Last week, Gizmodo's parent company G/O Media fired the staff of its Spanish-language site Gizmodo en Espanol and began replacing them with AI translations of English-language articles. "G/O Media's decision to eschew human writers for AI is part of a recent trend of media companies experimenting with AI tools as a way to maximize content output while minimizing human labor costs," reports Ars Technica. "However, the practice remains controversial within the broader journalism community." The Verge first reported the news. From the report: Previously, Gizmodo en Espanol had a small but dedicated team who wrote original content tailored specifically for Spanish-speaking readers, as well as producing translations of Gizmodo's English articles. The site represented Gizmodo's first foray into international markets when it launched in 2012 after being acquired from Guanabee. Newly published articles on the site now contain a link to the English version of the article and a disclaimer stating (via our translation from Google Translate), "This content has been automatically translated from the source material. Due to the nuances of machine translation, there may be slight differences. For the original version, click here."

So far, Gizmodo's pivot to AI translation hasn't gone smoothly. On social media site X, journalist and Gizmodo reader Victor Millan noted that some of the site's new articles abruptly switch from Spanish to English midway through, possibly due to glitches in the AI translation system. [...] For Spanish-speaking audiences seeking news about science, technology, and Internet culture, the loss of original reporting from Gizmodo en Espanol is potentially a major blow. And while AI translation technology has improved significantly over the past decade, experts say it still can't fully replace human translators. Subtle errors, mistranslations, and lack of cultural knowledge can impair the quality of automatically translated content.

Vanity Fair revisits the many warning signs about OceanGate's Titan submersible prior to an implosion on June 18th that killed all five passengers onboard.

A professional expedition leader tells their reporter that "This tragedy was predicted. It was avoidable. It was inevitable." As the world now knows, Stockton Rush touted himself as a maverick, a disrupter, a breaker of rules. So far out on the visionary curve that, for him, safety regulations were mere suggestions. "If you're not breaking things, you're not innovating," he declared at the 2022 GeekWire Summit. "If you're operating within a known environment, as most submersible manufacturers do, they don't break things. To me, the more stuff you've broken, the more innovative you've been." In a culture that has adopted the ridiculous mantra "move fast and break things," that type of arrogance can get a person far. But in the deep ocean, the price of admission is humility — and it's nonnegotiable...

In December 2015, two years before the Titan was built, Rush had lowered a one third scale model of his 4,000-meter-sub-to-be into a pressure chamber and watched it implode at 4,000 psi, a pressure equivalent to only 2,740 meters. The test's stated goal was to "validate that the pressure vessel design is capable of withstanding an external pressure of 6,000 psi — corresponding to...a depth of about 4,200 meters." He might have changed course then, stood back for a moment and reconsidered. But he didn't. Instead, OceanGate issued a press release stating that the test had been a resounding success because it "demonstrates that the benefits of carbon fiber are real."
OceanGate's director of marine operations later issued a Quality Control Inspection Report filled with warnings: These included missing bolts and improperly secured batteries, components zip-tied to the outside of the sub. O-ring grooves were machined incorrectly (which could allow water ingress), seals were loose, a highly flammable, petroleum-based material lined the Titan's interior... Yet even those deficiencies paled in comparison to what Lochridge observed on the hull. The carbon fiber filament was visibly coming apart, riddled with air gaps, delaminations, and Swiss cheese holes — and there was no way to fix that short of tossing the hull in a dumpster...

Rush's response was to fire Lochridge immediately, serve him and his wife with a lawsuit (although Carole Lochridge didn't work at OceanGate or even in the submersible industry) for breach of contract, fraud, unjust enrichment, and misappropriation of trade secrets; threaten their immigration status; and seek to have them pay OceanGate's legal fees.
The article also tells a story about OceanGate's 240-foot dive to the wreck of the Andrea Doria in 2016. The article claims that Rush disregarded safety instructions, then "landed too close, got tangled in the current, managed to wedge the sub beneath the Andrea Doria's crumbling bow, and descended into a full-blown panic..."

The article's author marvels that five years ago, "I didn't yet know how reckless, how heedless, how insane the Titan was." They'd once even considered booking a trip on the OceanGate's submersible — until receiving this advice from the chief pilot of the University of Hawaii's two deep-sea submarines. "Do not get into that sub. He is going to have a major accident."

The Verge writes that "LK-99 hasn't turned out to be the miraculous superconductor some people initially claimed it was..." [T]he results so far indicate that LK-99 is not a superconductor, at room temperature or otherwise. A slew of research groups have released studies that counter claims originally made about LK-99. "With a great deal of sadness, we now believe that the game is over. LK99 is NOT a superconductor, not even at room temperatures (or at very low temperatures). It is a very highly resistive poor quality material. Period. No point in fighting with the truth," the University of Maryland's Condensed Matter Theory Center (CMTC) posted on August 7th... [The last words of their tweet? "Data have spoken."]

Labs hurriedly published their own results on ArXiv, the same server for preprints (papers that haven't undergone peer review) where the original papers on LK-99 first appeared. Now, a body of evidence has piled up that disproves claims about LK-99. "There is no sign of superconductivity in LK-99 at room temperature," says one preprint from the CSIR-National Physical Laboratory in India. (That was one of the papers cited by the University of Maryland's Condensed Matter Theory Center this week when it posted that "the game is over....") [H]opes that levitation meant that LK-99 is a superconductor were dashed this week after another preprint posed another explanation for why the material might float. The International Center for Quantum Materials in China found evidence that the material is ferromagnetic. That means it can be magnetized and then attracted or repelled by other magnetic materials (iron, for example, is ferromagnetic)...

[T]here are already well over a dozen papers on ArXiv casting doubt on LK-99. "There may be room temperature superconductors to find, but this does not seem to be one," Chris Grovenor, professor of materials at the University of Oxford and director of the Centre for Applied Superconductivity, tells The Verge in an email.
The Washington Post reports that one of physicists who co-authored the discovery paper "countered in an email that other research groups' failure to replicate their results are probably because they lack 'know how' in developing the sample the same way."

"Stability AI, the startup behind the image-generating model Stable Diffusion, is launching a new service that turns sketches into images," reports TechCrunch.

Stable Doodle is online now and "free, but subject to limits," according to TechCrunch's article. And their reporter adds that the example images selected by the company to showcase their new technology "looked quite good, at least in comparison to the doodle that inspired them." "Stable Doodle is geared toward both professionals and novices, regardless of their familiarity with AI tools," Stability AI writes in a blog post shared with TechCrunch via email. "With Stable Doodle, anyone with basic drawing skills and online access can generate high-quality original images in seconds..."

In addition to a sketch, Stable Doodle accepts a prompt to guide the image generation process, such as "A comfy chair, 'isometric' style" or "Cat with a jeans jacket, 'digital art' style." There's a limit to the customization, though — at launch, Stable Doodle only supports 14 styles of art.

Stability AI envisions Stable Doodle serving as a tool for designers, illustrators and other professionals to "free up valuable time" and "maximize efficiency" in their work. At the same time, the company cautions that the quality of output images is dependent on the detail of the initial drawing and the descriptiveness of the prompt, as well as the complexity of the scene being depicted. "Ideas drawn as sketches can be immediately implemented into works to create designs for clients, material for presentation decks and websites or even create logos," the company proposes.

An anonymous reader quotes a report from France 24: The scale of plastic pollution is growing, relentlessly. The world is producing twice as much plastic waste as two decades ago, reaching 353 million tonnes in 2019, according to OECD figures. The vast majority goes into landfills, gets incinerated or is "mismanaged," meaning left as litter or not correctly disposed of. Just 9 percent of plastic waste is recycled. Ramping up plastic recycling might seem like a logical way to transform waste into a resource. But recent studies suggest that recycling plastic poses its own environmental and health risks, including the high levels of microplastics and harmful toxins produced by the recycling process that can be dangerous for people, animals and the environment. [...]

The share of plastic waste that is recycled globally is expected to rise to 17 percent by 2060, according to figures from the OECD. But recycling more will not address a major issue: after being recycled once or twice, most plastics come to a dead end. "There's a myth with plastic recycling that if the quality is good enough the plastics can be recycled back into plastic bottles," says Natalie Fee, the founder of City to Sea, a UK-based environmental charity. "But as it goes through the system, it becomes lower- and lower-grade plastic. It's down-cycled into things like drain pipes or sometimes fleece clothing. But those items can't be recycled afterwards."

It is therefore difficult to make the case that recycled plastic is a sustainable material, said Graham Forbes, Global Plastics Campaign leader at Greenpeace USA, in a statement this week. "Plastics have no place in a circular economy. It's clear that the only real solution to ending plastic pollution is to massively reduce plastic production." And it is impossible for increased recycling to keep pace with the amount of plastic waste being produced -- which is expected to almost triple by 2060. "There's no way that we can recycle our way out of this," added [Therese Karlsson, science and technical adviser at the International Pollutants Elimination Network (IPEN)]. "Not as it works today. Because today, plastic recycling is not working." "More than two-thirds of UN member states agreed in March last year to develop a legally binding agreement on plastic pollution by 2024, and the second round of meetings to draw up the treaty began on Monday in Paris and will run through Friday," notes the report. "UN Environment Program (UNEP), which is hosting the talks, released a roadmap to reduce plastic waste by 80 percent by 2040."

Karlsson is attending the talks, and she sees reason for hope. "The plastics treaty is an incredible opportunity to protect human health and the environment from plastic pollution. Doing that would mean phasing out toxic chemicals from plastics, ensuring transparency across the plastic life cycle and also decreasing plastic production."

An anonymous reader quotes a report from Motherboard: It was only a matter of time before the wave of artificial intelligence-generated voice startups became a play thing of internet trolls. On Monday, ElevenLabs, founded by ex-Google and Palantir staffers, said it had found an "increasing number of voice cloning misuse cases" during its recently launched beta. ElevenLabs didn't point to any particular instances of abuse, but Motherboard found 4chan members appear to have used the product to generate voices that sound like Joe Rogan, Ben Sharpio, and Emma Watson to spew racist and other sorts of material. ElevenLabs said it is exploring more safeguards around its technology.

The clips uploaded to 4chan on Sunday are focused on celebrities. But given the high quality of the generated voices, and the apparent ease at which people created them, they highlight the looming risk of deepfake audio clips. In much the same way deepfake video started as a method for people to create non-consensual pornography of specific people before branching onto other use cases, the trajectory of deepfake audio is only just beginning. [...] The clips run the gamut from harmless, to violent, to transphobic, to homophobic, to racist. One 4chan post that included a wide spread of the clips also contained a link to the beta from ElevenLabs, suggesting ElevenLabs' software may have been used to create the voices.

On its website ElevenLabs offers both "speech synthesis" and "voice cloning." For the latter, ElevenLabs says it can generate a clone of someone's voice from a clean sample recording, over one minute in length. Users can quickly sign up to the service and start generating voices. ElevenLabs also offers "professional cloning," which it says can reproduce any accent. Target use cases include voicing newsletters, books, and videos, the company's website adds. [...] On Monday, shortly after the clips circulated on 4chan, ElevenLabs wrote on Twitter that "Crazy weekend -- thank you to everyone for trying out our Beta platform. While we see our tech being overwhelmingly applied to positive use, we also see an increasing number of voice cloning misuse cases." ElevenLabs added that while it can trace back any generated audio to a specific user, it was exploring more safeguards. These include requiring payment information or "full ID identification" in order to perform voice cloning, or manually verifying every voice cloning request.

An impressive new AI system from Google can generate music in any genre given a text description. But the company, fearing the risks, has no immediate plans to release it. From a report: Called MusicLM, Google's certainly isn't the first generative AI system for song. There's been other attempts, including Riffusion, an AI that composes music by visualizing it, as well as Dance Diffusion, Google's own AudioML and OpenAI's Jukebox. But owing to technical limitations and limited training data, none have been able to produce songs particularly complex in composition or high-fidelity. MusicLM is perhaps the first that can.

Detailed in an academic paper, MusicLM was trained on a data set of 280,000 hours of music to learn to generate coherent songs for descriptions of -- as the creators put it -- "significant complexity" (e.g. "enchanting jazz song with a memorable saxophone solo and a solo singer" or "Berlin '90s techno with a low bass and strong kick." Its songs, remarkably, sound something like a human artist might compose, albeit not necessarily as inventive or musically cohesive. [...] That's not to suggest MusicLM's flawless -- far from it, truthfully. Some of the samples have a distorted quality to them, an unavoidable side effect of the training process. And while MusicLM can technically generate vocals, including choral harmonies, they leave a lot to be desired. Still, the Google researchers note the many ethical challenges posed by a system like MusicLM, including a tendency to incorporate copyrighted material from training data into the generated songs.

Researchers have spent decades trying to figure out how ancient Romans were able to make concrete that's survived for two millennia. "Now, a team of investigators from MIT, Harvard University, and laboratories in Italy and Switzerland, has made progress in this field, discovering ancient concrete-manufacturing strategies that incorporated several key self-healing functionalities," reports MIT News. From the report: For many years, researchers have assumed that the key to the ancient concrete's durability was based on one ingredient: pozzolanic material such as volcanic ash from the area of Pozzuoli, on the Bay of Naples. This specific kind of ash was even shipped all across the vast Roman empire to be used in construction, and was described as a key ingredient for concrete in accounts by architects and historians at the time. Under closer examination, these ancient samples also contain small, distinctive, millimeter-scale bright white mineral features, which have been long recognized as a ubiquitous component of Roman concretes. These white chunks, often referred to as "lime clasts," originate from lime, another key component of the ancient concrete mix.

Previously disregarded as merely evidence of sloppy mixing practices, or poor-quality raw materials, the new study suggests that these tiny lime clasts gave the concrete a previously unrecognized self-healing capability. [...] Upon further characterization of these lime clasts, using high-resolution multiscale imaging and chemical mapping techniques [...], the researchers gained new insights into the potential functionality of these lime clasts. Historically, it had been assumed that when lime was incorporated into Roman concrete, it was first combined with water to form a highly reactive paste-like material, in a process known as slaking. But this process alone could not account for the presence of the lime clasts. [MIT professor of civil and environmental engineering, Adam Masic] wondered: "Was it possible that the Romans might have actually directly used lime in its more reactive form, known as quicklime?"

Studying samples of this ancient concrete, he and his team determined that the white inclusions were, indeed, made out of various forms of calcium carbonate. And spectroscopic examination provided clues that these had been formed at extreme temperatures, as would be expected from the exothermic reaction produced by using quicklime instead of, or in addition to, the slaked lime in the mixture. Hot mixing, the team has now concluded, was actually the key to the super-durable nature. "The benefits of hot mixing are twofold," Masic says. "First, when the overall concrete is heated to high temperatures, it allows chemistries that are not possible if you only used slaked lime, producing high-temperature-associated compounds that would not otherwise form. Second, this increased temperature significantly reduces curing and setting times since all the reactions are accelerated, allowing for much faster construction."

During the hot mixing process, the lime clasts develop a characteristically brittle nanoparticulate architecture, creating an easily fractured and reactive calcium source, which, as the team proposed, could provide a critical self-healing functionality. As soon as tiny cracks start to form within the concrete, they can preferentially travel through the high-surface-area lime clasts. This material can then react with water, creating a calcium-saturated solution, which can recrystallize as calcium carbonate and quickly fill the crack, or react with pozzolanic materials to further strengthen the composite material. These reactions take place spontaneously and therefore automatically heal the cracks before they spread. Previous support for this hypothesis was found through the examination of other Roman concrete samples that exhibited calcite-filled cracks. According to MIT, the team is working to commercialize their modified cement material.

The findings have been published in the journal Science Advances.

"The nurse said to send photos so the doctor could review them in advance," the New York Times reports, decribing how an ordeal began in February of 2021 for a software engineer named Mark who had a sick son: Mark's wife grabbed her husband's phone and texted a few high-quality close-ups of their son's groin area to her iPhone so she could upload them to the health care provider's messaging system. In one, Mark's hand was visible, helping to better display the swelling. Mark and his wife gave no thought to the tech giants that made this quick capture and exchange of digital data possible, or what those giants might think of the images. With help from the photos, the doctor diagnosed the issue and prescribed antibiotics, which quickly cleared it up....

Two days after taking the photos of his son, Mark's phone made a blooping notification noise: His account had been disabled because of "harmful content" that was "a severe violation of Google's policies and might be illegal." A "learn more" link led to a list of possible reasons, including "child sexual abuse & exploitation...." He filled out a form requesting a review of Google's decision, explaining his son's infection. At the same time, he discovered the domino effect of Google's rejection. Not only did he lose emails, contact information for friends and former colleagues, and documentation of his son's first years of life, his Google Fi account shut down, meaning he had to get a new phone number with another carrier. Without access to his old phone number and email address, he couldn't get the security codes he needed to sign in to other internet accounts, locking him out of much of his digital life....

A few days after Mark filed the appeal, Google responded that it would not reinstate the account, with no further explanation. Mark didn't know it, but Google's review team had also flagged a video he made and the San Francisco Police Department had already started to investigate him.... In December 2021, Mark received a manila envelope in the mail from the San Francisco Police Department. It contained a letter informing him that he had been investigated as well as copies of the search warrants served on Google and his internet service provider. An investigator, whose contact information was provided, had asked for everything in Mark's Google account: his internet searches, his location history, his messages and any document, photo and video he'd stored with the company. The search, related to "child exploitation videos," had taken place in February, within a week of his taking the photos of his son.

Mark called the investigator, Nicholas Hillard, who said the case was closed. Mr. Hillard had tried to get in touch with Mark but his phone number and email address hadn't worked....

Mark appealed his case to Google again, providing the police report, but to no avail.... A Google spokeswoman said the company stands by its decisions...
"The day after Mark's troubles started, the same scenario was playing out in Texas," the Times notes, quoting a technologist at the EFF who speculates other people experiencing the same thing may not want to publicize it. "There could be tens, hundreds, thousands more of these."

Reached for a comment on the incident, Google told the newspaper that "Child sexual abuse material is abhorrent and we're committed to preventing the spread of it on our platforms."

An anonymous reader writes: Posing as a scholar, a Chinese woman spent years writing alternative accounts of medieval Russian history on Chinese Wikipedia, conjuring imaginary states, battles, and aristocrats in one of the largest hoaxes on the open-source platform. The scam was exposed last month by Chinese novelist Yifan, who was researching for a book when he came upon an article on the Kashin silver mine. Discovered by Russian peasants in 1344, the Wikipedia entry goes, the mine engaged more than 40,000 slaves and freedmen, providing a remarkable source of wealth for the Russian principality of Tver in the 14th and 15th centuries as well as subsequent regimes. The geological composition of the soil, the structure of the mine, and even the refining process were fleshed out in detail in the entry.

Yifan thought he'd found interesting material for a novel. Little did he know he'd stumbled upon an entire fictitious world constructed by a user known as Zhemao. It was one of 206 articles she has written on Chinese Wikipedia since 2019, weaving facts into fiction in an elaborate scheme that went uncaught for years and tested the limits of crowdsourced platforms' ability to verify information and fend off bad actors. "The content she wrote is of high quality and the entries were interconnected, creating a system that can exist on its own," veteran Chinese Wikipedian John Yip told VICE World News. "Zhemao single-handedly invented a new way to undermine Wikipedia."

Yifan was tipped off when he ran the silver mine story by Russian speakers and fact-checked Zhemao's references, only to find that the pages or versions of the books she cited did not exist. People he consulted also called out her lengthy entries on ancient conflicts between Slavic states, which could not be found in Russian historical records. "They were so rich in details they put English and Russian Wikipedia to shame," Yifan wrote on Zhihu, a Chinese site similar to Quora, where he shared his discovery last month and caused a stir. The scale of the scam came to light after a group of volunteer editors and other Wikipedians, such as Yip, combed through her past contributions to nearly 300 articles. "As a punishment, Zhemao and her affiliated accounts were suspended permanently," adds VICE World News. "Most of her articles were deleted based on community consensus. Some Wikipedians even wrote to experts, seeking help to separate the wheat from the chaff." A spokesperson of the Wikimedia Foundation told VICE World News in an email that volunteers are still "continuing to review additional articles that may have been affected."

The report goes on to say that Zhemao speaks neither English nor Russian and is a housewife with only a high school degree. She came clean in an apology letter issued on her Wikipedia account last month. "The hoax started with an innocuous intention," reports VICE. "Unable to comprehend scholarly articles in their original language, she pieced sentences together with a translation tool and filled in the blanks with her own imagination. [...] Before long, they had accumulated into tens of thousands of characters, which she was reluctant to delete."

"The alternative accounts were imaginary friends she 'cosplayed' as she was bored and alone, given her husband was away most of the time and she didn't have any friends. She also apologized to actual experts on Russia, whom she had attempted to cozy up to and later impersonated."

For 3-D printing, whose origins stretch back to the 1980s, the technology, economic and investment trends may finally be falling into place for the industry's commercial breakout, according to manufacturing experts, business executives and investors. From a report: They say 3-D printing, also called additive manufacturing, is no longer a novelty technology for a few consumer and industrial products, or for making prototype design concepts. "It is now a technology that is beginning to deliver industrial-grade product quality and printing in volume," said Jorg Bromberger, a manufacturing expert at McKinsey & Company. He is the lead author of a recent report by the consulting firm titled, "The Mainstreaming of Additive Manufacturing."

3-D printing refers to making something from the ground up, one layer at a time. Computer-guided laser beams melt powders of metal, plastic or composite material to create the layers. In traditional "subtractive" manufacturing, a block of metal, for example, is cast and then a part is carved down into shape with machine tools. In recent years, some companies have used additive technology to make specialized parts. General Electric relies on 3-D printing to make fuel nozzles for jet engines, Stryker makes spinal implants and Adidas prints latticed soles for high-end running shoes. Dental implants and teeth-straightening devices are 3-D printed. During the Covid-19 pandemic, 3-D printers produced emergency supplies of face shields and ventilator parts.

Today, experts say, the potential is far broader than a relative handful of niche products. The 3-D printing market is expected to triple to nearly $45 billion worldwide by 2026, according to a report by Hubs, a marketplace for manufacturing services. The Biden administration is looking to 3-D printing to help lead a resurgence of American manufacturing. Additive technology will be one of "the foundations of modern manufacturing in the 21st century," along with robotics and artificial intelligence, said Elisabeth Reynolds, special assistant to the president for manufacturing and economic development.

An anonymous reader quotes a report from the Financial Times: Meta is facing a growing backlash for the charges imposed on apps created for its virtual reality headsets, as developers complain about the commercial terms set around futuristic devices that the company hopes will help create a multibillion-dollar consumer market. [...] But several developers told the Financial Times of their frustration that Meta, which is seen as having an early lead in a nascent market, has insisted on a charging model for its VR app store similar to what exists today on smartphones. This is despite Meta chief Mark Zuckerberg being strongly critical in the past of charging policies on existing mobile app stores.

"Don't confuse marketing with reality -- it's good marketing to pick on Apple. But it doesn't mean Meta won't do the exact same thing," said Seth Siegel, global head of AI and cyber security at Infosys Consulting. "There is no impetus for them to be better." The "Quest Store" for Meta's Quest 2, by far the most popular VR headset on the market, takes a 30 percent cut from digital purchases and charges 15-30 percent on subscriptions, similar to the fees charged by Apple and Android. "Undoubtedly there are services provided -- they build amazing hardware and provide store services," said Daniel Sproll, chief executive of Realities.io, an immersive realities start-up behind the VR game Puzzling Places. "But the problem is that it feels like everybody agreed on this 30 percent and that's what we're stuck with. It doesn't feel like there's any competition. The Chinese companies coming out with headsets are the same. Why would they change it?"

Meta defended its policies, pointing out that unlike iPhone owners, Quest users can install apps outside its official store through SideQuest, a third-party app store, or make use of App Lab, its less restricted, more experimental app store. "We want to foster choice and competition in the VR ecosystem," Meta said. "And it's working -- our efforts have produced a material financial return for developers: as we announced earlier this year, over $1 billion has been spent on games and apps in the Meta Quest Store." Developers welcome these alternatives but say their impact is limited. SideQuest has been downloaded just 396,000 times, versus 19 million for the Oculus app, according to Sensor Tower. App Lab, meanwhile, still takes a 30 percent cut of purchases. Developers are also frustrated with Meta's shift to a more restrictive approach to allowing apps on its VR app store.

Chris Pruett, Meta's content ecosystem director, said Meta found that lax standards resulted in too many users being frustrated by low-quality content, so the company has opted to play more of a gatekeeper role. But developers said the resulting barriers could lack transparency.

"Getting something on the Quest store is painful," said Lyron Bentovim, chief executive of the Glimpse Group, an immersive experiences group. "It's significantly worse than getting on Apple or Android stores."

Researchers in Japan have developed a new method for making 5-cm (2-in) wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data -- the equivalent of one billion Blu-Ray discs. New Atlas reports: [R]esearchers at Saga University and Adamant Namiki Precision Jewelery Co. in Japan have developed a new method for manufacturing ultra-high purity diamond wafers that are big enough for practical use. With this technique, the team says the resulting diamond wafers measure 5 cm across, and have such immense data density that they can theoretically store the equivalent of a billion Blu-Ray discs. One Blu-Ray can store up to 25 GB (assuming it's single-layered), which would mean this diamond wafer should be able to store a whopping 25 exabytes (EB) of data. The company calls these wafers Kenzan Diamond. The key is that these diamonds have a nitrogen concentration of under three parts per billion (ppb), making them incredibly pure. The researchers say that these are the largest wafers with that level of purity -- most others only get to 4 mm2 (0.006 in2) at most.

Achieving this requires a new manufacturing technique. Diamond wafers are made by growing the crystals on a substrate material, and that material is usually a flat surface. The problem is, the diamond can crack under the strain, degrading the quality. In the new process, the team made a relatively simple change -- the substrate surface was shaped like steps, which spreads the strain horizontally and prevents cracking. This allows them to make larger diamond wafers with higher purity. The team hopes to commercialize these diamond wafers in 2023, and in the meantime are already working towards doubling the diameter to 10 cm (4 in).

MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source. MIT News reports: This thin-film loudspeaker produces sound with minimal distortion while using a fraction of the energy required by a traditional loudspeaker. The hand-sized loudspeaker the team demonstrated, which weighs about as much as a dime, can generate high-quality sound no matter what surface the film is bonded to. To achieve these properties, the researchers pioneered a deceptively simple fabrication technique, which requires only three basic steps and can be scaled up to produce ultrathin loudspeakers large enough to cover the inside of an automobile or to wallpaper a room.

A typical loudspeaker found in headphones or an audio system uses electric current inputs that pass through a coil of wire that generates a magnetic field, which moves a speaker membrane, that moves the air above it, that makes the sound we hear. By contrast, the new loudspeaker simplifies the speaker design by using a thin film of a shaped piezoelectric material that moves when voltage is applied over it, which moves the air above it and generates sound. [...]

They tested their thin-film loudspeaker by mounting it to a wall 30 centimeters from a microphone to measure the sound pressure level, recorded in decibels. When 25 volts of electricity were passed through the device at 1 kilohertz (a rate of 1,000 cycles per second), the speaker produced high-quality sound at conversational levels of 66 decibels. At 10 kilohertz, the sound pressure level increased to 86 decibels, about the same volume level as city traffic. The energy-efficient device only requires about 100 milliwatts of power per square meter of speaker area. By contrast, an average home speaker might consume more than 1 watt of power to generate similar sound pressure at a comparable distance. The researchers showed the speaker in action, playing "We Are the Champions" by Queen. You can listen to it here.

The Seattle Times reports: The litany of manufacturing defects on the 787 Dreamliner is expanding as Boeing engineers take apart planes and discover new or more widespread issues, a Federal Aviation Administration internal memo indicates. The FAA memo, which was circulated internally Monday and reviewed by The Seattle Times, points to new concerns about a previously unreported defect caused by contamination of the carbon fiber composite material during fabrication of the large structures that make up the 787's wing, fuselage and tail. The memo also adds detail about the small out-of-tolerance gaps that have been discovered throughout the airplane structure: at the joins of the large fuselage sections, at a forward pressure bulkhead and in the structure surrounding the passenger and cargo doors. The FAA memo, which lists safety conditions affecting airplanes currently in service worldwide, states that these tiny gap defects are thought to be present in more than 1,000 Dreamliners.

These are not considered an immediate safety concern but could cause premature aging of the airframe.
Bloomberg reports these delays may hamper Boeing's efforts to pay down its $62 billion debt: Boeing is working to find and repair tiny structural imperfections about the width of a piece of paper in the carbon-fiber aircraft while addressing quality lapses among suppliers and their subcontractors. Both issues came to light as the Chicago-based planemaker did a deep dive in its factories and production system in the wake of two fatal crashes of its 737 Max... A Boeing spokesman wouldn't confirm a Wall Street Journal report Friday that deliveries aren't likely to restart until February or March... For each manufacturing glitch that strays from its design specifications, Boeing has to file a so-called notice of escapement with the FAA that evaluates the problem, recommends a fix and provides an engineering analysis to back up its finding. The company is still working through those notices, along with a broader inspection regimen for the 787, according to people familiar with the situation.

There are about 20 locations on Dreamliners where potential quality breaches have been identified, said one of the people, who asked not to be identified discussing a confidential matter. At a Boeing fabrication plant in South Carolina, for example, mechanics are inspecting the area surrounding doors at the rear of the aircraft for tiny gaps, one of the people said. Dreamliners continue to roll off the line in North Charleston at a slow rate of two planes a month, the person said. Conducting the inspections can be time consuming and costly since, in some areas of the plane, workers have to tear out passenger cabins to gain access...

The planemaker had initially requested permission to inspect a handful of planes and, if they passed, use its regimen for the rest of the undelivered aircraft, the people said. The FAA rejected that plan, and company and the regulator haven't yet agreed on an appropriate level of inspections, said one of the people.
