Beijing has quietly pulled the proposed curbs on the video game industry from the official website, weeks after the draft guidelines wiped tens of billions of dollars off the market value of local titans. From a report: The link to the draft rules was no longer accessible as of this morning, Haitong Securities reported earlier on Tuesday. Shares of Tencent and NetEase jumped on the news. "This could possibly indicate that there will be further changes in the new measures," wrote Haitong analysts in the note. The move follows Beijing also removing a key official -- the head of the publication bureau of Communist Party's Propaganda Department -- over the handling of the release of the draft rules, which caught investors and gaming giants by surprise.

One man living in Virginia oversaw "the laundering of some $7 million in fraudulently obtained gift cards" from Walmart in an international operation which over five years scammed hundreds of victims into sending the numbers over the phone, reports a new ProPublica investigation. (Citing court evidence that emerged after his arrested in 2021). Earlier that year, he complained to an associate that more and more people were competing to resell cards in China, eating into his profits. So many scammers were flocking to Walmart that he and his team regularly encountered them at self-checkout counters.... "We ran into quite a few at the store, and we even started chatting."
It was apparently so common that federal prosecutors started calling it "The Walmart scheme." And while the store is supposed to watch for customers who appear to be acting on a scammer's instructions, "Too often, Walmart has failed." America's largest retailer has long been a facilitator of fraud on a mass scale, a ProPublica investigation has found. For roughly a decade, Walmart has resisted tougher enforcement while breaking promises to regulators and skimping on employee training, according to more than 50 interviews, internal documents supplied by former industry executives, court filings and other public records...More than $1 billion in fraud losses were routed through the company's financial systems between 2013 and 2022, according to filings by the Federal Trade Commission and court cases analyzed by ProPublica. That has helped fuel a boom in financial chicanery. Americans, many of them elderly, were swindled out of $27 billion between 2013 and 2022, according to the FTC...

Walmart has a financial incentive to avoid cracking down. It makes money each time a Walmart gift card is used and earns a fee when another brand of card is bought. And it receives one commission when a person sends a money transfer and a second when the recipient picks it up. The company's financial services business generates hundreds of millions in annual profits. (Its filings do not provide specific figures for gift cards and money transfers.) "They were concerned about the bucks. That's all," Nick Alicea, a former fraud team leader for the U.S. Postal Inspection Service who investigated Walmart for years, told ProPublica. Walmart's deficiencies have repeatedly attracted government scrutiny. In 2017, the attorneys general of New York and Pennsylvania investigated Walmart over concerns that it was "reaping the benefits" of gift card fraud. The investigation concluded a year later with Walmart promising to restrict or eliminate the use of its gift cards to purchase other gift cards...

Instead, the company let the practice continue until 2022 — even after it knew that millions of dollars were being laundered through its stores. The FTC sued Walmart in 2022, alleging it "turned a blind eye" as criminals took advantage of its money transfer service. Walmart, the FTC claimed, pocketed millions in fees while "letting fraudsters fleece its customers." Summarizing the FTC's evidence, a federal judge in the case wrote that "Walmart knew that its services were used by fraudsters" and that the company was repeatedly warned about certain stores where "twenty-five, fifty, or even seventy-five percent of money transfer activity was fraudulent." Separately, a federal grand jury in Pennsylvania is hearing evidence of possible criminal conduct in Walmart's money transfer business, according to corporate filings that did not detail the allegations.
While the FTC says Americans were swindled out of $27 billion between 2013 and 2022, Walmart responded to ProPublica's investigation by pointing out it's refunded $4 million to gift-card fraud victims, and also blocked more than $700 million in suspicious money transfers. "We have a robust anti-fraud program and other controls to help stop scammers and other criminals who may use the financial services we offer to harm our customers." The company's legal filings in the FTC case struck a different tone. Walmart is seeking to dismiss the suit, partly on the grounds that it has "no responsibility to protect against the criminal conduct of third parties." Though fraud is "deeply unfortunate," Walmart argues, such schemes are "reasonably avoidable by consumers."
Other interesting quotes from the article:

• "Walmart outlets at one point accounted for the top 20 locations for fraud nationally among chains that partnered with MoneyGram, according to internal documents."

• "In a single week in March 2017, consumers claiming they'd been duped into a money transfer filed 610 complaints about Walmart, according to documents obtained by ProPublica. CVS ranked second, with 47."

• "Site inspections routinely found that Walmart staff lacked anti-fraud training and that employees failed to ask screening questions..."

• Walmart resisted MoneyGram's attempts to fight fraud [according to the former fraud team leader for the postal inspector's office in Harrisburg, Pennsylvania, who investigated MoneyGram and Walmart].

U.S. lawmakers have banned the Defense Department from buying batteries produced by China's biggest manufacturers. "The rule implemented as part of the latest National Defense Authorization Act that passed on Dec. 22 will prevent procuring batteries from Contemporary Amperex Technology Co. Ltd., BYD Co. and four other Chinese companies beginning in October 2027," reports Bloomberg. From the report: The measure doesn't extend to commercial purchases by companies such as Ford, which is licensing technology from CATL to build electric-vehicle batteries in Michigan. Tesla also sources some of its battery cells from BYD, which became the new top-selling EV maker globally in the fourth quarter. The four other manufacturers whose batteries will be banned are Envision Energy Ltd., EVE Energy Co., Gotion High Tech Co. and Hithium Energy Storage Technology Co.

The decision still requires Pentagon officials to more clearly define the reach of the new rule. It adds to previous provisions outlined by the NDAA that decoupled the Defense Department's supply chain from China, including restrictions on use of Chinese semiconductors. While the Defense Department bans apply strictly to defense procurement, industries and lawmakers closely follow the rules as a guide for what materials, products and companies to trust in their own course of business.

China's Huawei will not support Android apps on the latest iteration of its in-house Harmony operating system, domestic financial media Caixin reported, as the company looks to bolster its own software ecosystem. From a report: The company plans to roll out a developer version of its HarmonyOS Next platform in the second quarter of this year followed by a full commercial version in the fourth quarter, it said in a company statement highlighting the launch event for the platform in its home city of Shenzhen on Thursday.

Huawei first unveiled its proprietary Harmony system in 2019 and prepared to launch it on some smartphones a year later after U.S. restrictions cut its access to Google's technical support for its Android mobile OS. However, earlier versions of Harmony allowed apps built for Android to be used on the system, which will no longer be possible, according to Caixin.

Organized crime is mining sand from rivers and coasts to feed demand worldwide, ruining ecosystems and communities. Can it be stopped? Scientific American reports: Very few people are looking closely at the illegal sand system or calling for changes, however, because sand is a mundane resource. Yet sand mining is the world's largest extraction industry because sand is a main ingredient in concrete, and the global construction industry has been soaring for decades. Every year the world uses up to 50 billion metric tons of sand, according to a United Nations Environment Program report. The only natural resource more widely consumed is water. A 2022 study by researchers at the University of Amsterdam concluded that we are dredging river sand at rates that far outstrip nature's ability to replace it, so much so that the world could run out of construction-grade sand by 2050. The U.N. report confirms that sand mining at current rates is unsustainable.

The greatest demand comes from China, which used more cement in three years (6.6 gigatons from 2011 through 2013) than the U.S. used in the entire 20th century (4.5 gigatons), notes Vince Beiser, author of The World in a Grain. Most sand gets used in the country where it is mined, but with some national supplies dwindling, imports reached $1.9 billion in 2018, according to Harvard's Atlas of Economic Complexity. Companies large and small dredge up sand from waterways and the ocean floor and transport it to wholesalers, construction firms and retailers. Even the legal sand trade is hard to track. Two experts estimate the global market at about $100 billion a year, yet the U.S. Geological Survey Mineral Commodity Summaries indicates the value could be as high as $785 billion.

Sand in riverbeds, lake beds and shorelines is the best for construction, but scarcity opens the market to less suitable sand from beaches and dunes, much of it scraped illegally and cheaply. With a shortage looming and prices rising, sand from Moroccan beaches and dunes is sold inside the country and is also shipped abroad, using organized crime's extensive transport networks, Abderrahmane has found. More than half of Morocco's sand is illegally mined, he says.

The credibility of the Cop28 agreement to "transition away" from fossil fuels rides on the world's biggest historical polluters like the US, UK and Canada rethinking current plans to expand oil and gas production, according to the climate negotiator representing 135 developing countries. The Guardian: In an exclusive interview with the Guardian, Pedro Pedroso, the outgoing president of the G77 plus China bloc of developing countries, warned that the landmark deal made at last year's climate talks in Dubai risked failing. "We achieved some important outcomes at Cop28 but the challenge now is how we translate the deal into meaningful action for the people," Pedroso said. "As we speak, unless we lie to ourselves, none of the major developed countries, who are the most important historical emitters, have policies that are moving away from fossil fuels, on the contrary, they are expanding," said Pedroso.

These countries must also deliver adequate finance for poorer nations to transition -and adapt to the climate crisis. In Dubai, Sultan Al Jaber, Cop28 president and chief of the Emirates national oil company, was subject to widespread scrutiny -- understandable given that the UAE is the world's seventh biggest oil producer with the fifth largest gas reserves. Yet the US was by far the biggest oil and gas producer in the world last year -- setting a new record, during a year that was the hottest ever recorded. The US, UK, Canada, Australia and Norway account for 51% of the total planned oil and gas expansion by 2050, according to research by Oil Change International. "It's very easy to label some emerging economies, especially the Gulf states, as climate villains, but this is very unfair by countries with historic responsibilities -- who keep trying to scapegoat and deviate the attention away from themselves. Just look at US fossil fuel plans and the UK's new drilling licenses for the North Sea, and Canada which has never met any of its emission reduction goals, not once," said Pedroso, a Cuban diplomat.

With NASA's Artemis moon program now targeting September 2025 for its Artemis 2 mission and September 2026 for Artemis 3, some members of Congress are concerned about the potential repercussions, particularly with China's growing ambitions in lunar exploration. "For the United States and its partners not to be on the moon when others are on the moon is unacceptable," said Mike Griffin, former NASA administrator. "We need a program that is consistent with that theme. Artemis is not that program. We need to restart it, not keep it on track." Space.com reports: The U.S. House of Representatives' Committee on Science, Space and Technology held a hearing about the new Artemis plan today (Jan. 17), and multiple members voiced concern about the slippage. "I remind my colleagues that we are not the only country interested in sending humans to the moon," Committee Chairman Frank Lucas (R-OK) said in his opening remarks. "The Chinese Communist Party is actively soliciting international partners for a lunar mission -- a lunar research station -- and has stated its ambition to have human astronauts on the surface by 2030," he added. "The country that lands first will have the ability to set a precedent for whether future lunar activities are conducted with openness and transparency, or in a more restricted manner."

The committee's ranking member, California Democrat Zoe Lofgren (D-CA), voiced similar sentiments. "Let me be clear: I support Artemis," she said in her opening remarks. "But I want it to be successful, especially with China at our heels. And we want to be helpful here in the committee in ensuring that Artemis is strong and staying on track as we look to lead the world, hand-in-hand with our partners, in the human exploration of the moon and beyond." Several other committee members stressed that the new moon race is part of a broader competition with China, and that coming in second could imperil U.S. national security.

"It's no secret that China has a goal to surpass the United States by 2045 as global leaders in space. We can't allow this to happen," Rich McCormick (R-GA) said during the hearing. "I think the leading edge that we have in space technology will protect the United States -- not just the economy, but technologies that can benefit humankind." And Bill Posey (R-FL) referred to space as the "ultimate military high ground," saying that whoever leads in the final frontier "will control the destiny of this Earth."

According to Bloomberg, China's chip import value dropped significantly by 15.4% in 2023, from $413 billion to $349 billion. "Chip sales were down across the board in 2023 thanks to a weakening global economy, but China's chip imports indicate that its economy might be in trouble," reports Tom's Hardware. "The country's inability to import cutting-edge silicon is also certainly a factor in its decreasing chip imports." From the report: In 2022, the value of chip imports to China stood at $413 billion, and in 2023 the country only imported chips worth a total of $349 billion, a 15.4% decrease in value. That a drop happened at all isn't surprising; even TSMC, usually considered to be one of the most advanced fabbing corporation in the world, saw its sales decline by 4.5%. However, a 15.4% decrease in shipments is much more significant, and indicates China has particular issues other than weaker demand across the world.

China's ongoing economic issues, such as its high deflation could play a part. Deflation is when currency increases in value, the polar opposite of inflation, when currency loses value. As inflation has been a significant problem for countries such as the U.S. and UK, deflation might sound much more appealing, but economically it can be problematic. A deflationary economy encourages consumers not to spend, since money is increasing in value, meaning buyers can purchase more if they wait. In other words, deflation decreases demand for products like semiconductors.

However, shipment volume only decreased by 10.8% compared to the 15.4% decline in value, meaning the chips that China didn't buy in 2023 were particularly valuable. This likely reflects U.S. sanctions on China, which prevents it from buying top-end graphics cards, especially from Nvidia. The H100, H200, GH200, and the RTX 4090 are illegal to ship to China, and they're some of Nvidia's best GPUs. The moving target for U.S. sanctions could also make exporters and importers more tepid, as it's hard to tell if more sanctions could suddenly upend plans and business deals.

An opinion piece in the Los Angeles Times imagines a world after "the largest coordinated deepfake attack in history... a steady flow of new deepfakes, mostly manufactured in Russia, North Korea, China and Iran." The breakthrough actually came in early 2026 from a working group of digital journalists from U.S. and international news organizations. Their goal was to find a way to keep deepfakes out of news reports... Journalism organizations formed the FAC Alliance — "Fact Authenticated Content" — based on a simple insight: There was already far too much AI fakery loose in the world to try to enforce a watermarking system for dis- and misinformation. And even the strictest labeling rules would simply be ignored by bad actors. But it would be possible to watermark pieces of content that deepfakes.

And so was born the voluntary FACStamp on May 1, 2026...

The newest phones, tablets, cameras, recorders and desktop computers all include software that automatically inserts the FACStamp code into every piece of visual or audio content as it's captured, before any AI modification can be applied. This proves that the image, sound or video was not generated by AI. You can also download the FAC app, which does the same for older equipment... [T]o retain the FACStamp, your computer must be connected to the non-profit FAC Verification Center. The center's computers detect if the editing is minor — such as cropping or even cosmetic face-tuning — and the stamp remains. Any larger manipulation, from swapping faces to faking backgrounds, and the FACStamp vanishes.

It turned out that plenty of people could use the FACStamp. Internet retailers embraced FACStamps for videos and images of their products. Individuals soon followed, using FACStamps to sell goods online — when potential buyers are judging a used pickup truck or secondhand sofa, it's reassuring to know that the image wasn't spun out or scrubbed up by AI.
The article envisions the world of 2028, with the authentication stamp appearing on everything from social media posts to dating app profiles: Even the AI industry supports the use of FACStamps. During training runs on the internet, if an AI program absorbs excessive amounts of AI-generated rather than authentic data, it may undergo "model collapse" and become wildly inaccurate. So the FACStamp helps AI companies train their models solely on reality. A bipartisan group of senators and House members plans to introduce the Right to Reality Act when the next Congress opens in January 2029. It will mandate the use of FACStamps in multiple sectors, including local government, shopping sites and investment and real estate offerings. Counterfeiting a FACStamp would become a criminal offense. Polling indicates widespread public support for the act, and the FAC Alliance has already begun a branding campaign.
But all this leaves Slashdot reader Bruce66423 with a question. "Is it really technically possible to achieve such a clear distinction, or would, in practice, AI be able to replicate the necessary authentication?"

"Chinese company Betavolt has announced an atomic energy battery for consumers with a touted 50-year lifespan," reports Tom's Hardware: The Betavolt BV100 will be the first product to launch using the firm's new atomic battery technology, constructed using a nickel -63 isotope and diamond semiconductor material. Betavolt says that its nuclear battery will target aerospace, AI devices, medical, MEMS systems, intelligent sensors, small drones, and robots — and may eventually mean manufacturers can sell smartphones that never need charging...

[T]he BV100, which is in the pilot stage ahead of mass production, doesn't offer a lot of power. This 15 x 15 x 5mm battery delivers 100 microwatts at 3 volts. It is mentioned that multiple BV100 batteries can be used together in series or parallel depending on device requirements. Betavolt also asserts that it has plans to launch a 1-watt version of its atomic battery in 2025. The new BV100 is claimed to be a disruptive product on two counts. Firstly, a safe miniature atomic battery with 50 years of maintenance-free stamina is a breakthrough. Secondly, Betavolt claims it is the only company in the world with the technology to dope large-size diamond semiconductor materials, as used by the BV100. It is using its 4th Gen diamond semiconductor material here...

[T]he Betavolt BV100 is claimed to be safe for consumers and won't leak radiation even if subjected to gunshots or puncture... Betavolt's battery uses a nickel -63 isotope as the energy source, which decays to a stable isotope of copper. This, plus the diamond semiconductor material, helps the BV100 operate stably in environments ranging from -60 to 120 degrees Celsius, according to the firm...

Betavolt will be well aware of devices with a greater thirst for power and teases that it is investigating isotopes such as strontium- 90, promethium- 147, and deuterium to develop atomic energy batteries with higher power levels and even longer service lives — up to 230 years.

Restrictive US policies limiting advanced chip exports to China have done little to dampen Qualcomm's enthusiasm for the world's second-largest economy. From a report: In an interview at CES 2024 in Las Vegas, CEO Cristiano Amon expressed confidence about Qualcomm's business in the country, its largest market by revenue. "If you have a leading technology, you're going to have a big business in China," he said. The San Diego-based firm finds itself in a difficult situation, as the White House and Congress ramp up a pressure campaign to curb the sale of US chips and chipmaking tools to China, citing national security concerns. The Biden administration has argued that China's access to advanced semiconductors could aid military advancements.

Meanwhile, in China, government agencies and state-owned firms have widened their ban on Apple's iPhones for employees. Qualcomm is one of Apple's biggest suppliers. China remains the largest semiconductor market in the world, with sales in the country accounting for one-third of the global market, according to the Semiconductor Industry Association.

Security researchers warned Apple as early as 2019 about vulnerabilities in its AirDrop wireless sharing function that Chinese authorities claim they recently used to track down users of the feature, the researchers told CNN, in a case that experts say has sweeping implications for global privacy. From a report: The Chinese government's actions targeting a tool that Apple customers around the world use to share photos and documents -- and Apple's apparent inaction to address the flaws -- revive longstanding concerns by US lawmakers and privacy advocates about Apple's relationship with China and about authoritarian regimes' ability to twist US tech products to their own ends.

AirDrop lets Apple users who are near each other share files using a proprietary mix of Bluetooth and other wireless connectivity without having to connect to the internet. The sharing feature has been used by pro-democracy activists in Hong Kong and the Chinese government has cracked down on the feature in response. A Chinese tech firm, Beijing-based Wangshendongjian Technology, was able to compromise AirDrop to identify users on the Beijing subway accused of sharing "inappropriate information," judicial authorities in Beijing said this week. Although Chinese officials portrayed the exploit as an effective law enforcement technique, internet freedom advocates are urging Apple to address the issue quickly and publicly.

U.S. software giant Ivanti has confirmed that hackers are exploiting two critical-rated vulnerabilities affecting its widely-used corporate VPN appliance, but said that patches won't be available until the end of the month. From a report: Ivanti said the two vulnerabilities -- tracked as CVE-2023-46805 and CVE-2024-21887 -- were found in its Ivanti Connect Secure software. Formerly known as Pulse Connect Secure, this is a remote access VPN solution that enables remote and mobile users to access corporate resources over the internet. Ivanti said it is aware of "less than 10 customers" impacted so far by the "zero day" vulnerabilities, described as such given Ivanti had zero time to fix the flaws before they were maliciously exploited.

An anonymous reader quotes a report from the New York Times: When Microsoft opened an advanced research lab in Beijing in 1998, it was a time of optimism about technology and China. The company hired hundreds of researchers for the lab, which pioneered Microsoft's work in speech, image and facial recognition and the kind of artificial intelligence that later gave rise to online chatbots likeChatGPT. The Beijing operation eventually became one of the most important A.I. labs in the world. Bill Gates, Microsoft's co-founder, called it an opportunity to tap China's "deep pool of intellectual talent." But as tensions between the United States and China have mounted over which nation will lead the world's technological future, Microsoft's top leaders -- including Satya Nadella, its chief executive, and Brad Smith, its president -- have debated what to do with the prized lab for at least the past year, four current and former Microsoft employees said.

The company has faced questions from U.S. officials over whether maintaining a 200-person advanced technologies lab in China is tenable, the people said. Microsoft said it had instituted guardrails at the lab, restricting researchers from politically sensitive work. The company, which is based in Redmond, Wash., said it had also opened an outpost of the lab in Vancouver, British Columbia, and would move some researchers from China to the location. The outpost is a backup if more researchers need to relocate, two people said. The idea of shutting down or moving the lab has come up, but Microsoft's leaders support continuing it in China, four people said. "We are as committed as ever to the lab and the world-class research of this team," Peter Lee, who leads Microsoft Research, a network of eight labs across the world, said in a statement. Using the lab's formal name, he added, "There has been no discussion or advocacy to close Microsoft Research Asia, and we look forward to continuing our research agenda."

A U.S.-born chip technology called RISC-V has become critical to China's ambitions. Washington is debating whether and how to limit the technology. From a report: It evolved from a university computer lab in California to a foundation for myriad chips that handle computing chores. RISC-V essentially provides a kind of common language for designing processors that are found in devices like smartphones, disk drives, Wi-Fi routers and tablets. RISC-V has ignited a new debate in Washington in recent months about how far the United States can or should go as it steadily expands restrictions on exporting technology to China that could help advance its military. That's because RISC-V, which can be downloaded from the internet for free, has become a central tool for Chinese companies and government institutions hoping to match U.S. prowess in designing semiconductors.

Last month, the House Select Committee on the Chinese Communist Party -- in an effort spearheaded by Representative Mike Gallagher, Republican of Wisconsin -- recommended that an interagency government committee study potential risks of RISC-V. Congressional aides have met with members of the Biden administration about the technology, and lawmakers and their aides have discussed extending restrictions to stop U.S. citizens from aiding China on RISC-V, according to congressional staff members. The Chinese Communist Party is "already attempting to use RISC-V's design architecture to undermine our export controls," Representative Raja Krishnamoorthi of Illinois, the ranking Democrat on the House select committee, said in a statement. He added that RISC-V's participants should be focused on advancing technology and "not the geopolitical interests of the Chinese Communist Party."

Arm Holdings, a British company that sells competing chip technology, has also lobbied officials to consider restrictions on RISC-V, three people with knowledge of the situation said. Biden administration officials have concerns about China's use of RISC-V but are wary about potential complications with trying to regulate the technology, according to a person familiar with the discussions. The debate over RISC-V is complicated because the technology was patterned after open-source software, the free programs like Linux that allow any developer to view and modify the original code used to make them. Such programs have prompted multiple competitors to innovate and reduce the market power of any single vendor.

The European climate agency Copernicus said Earth shattered global annual heat records in 2023, flirting with the world's agreed-upon warming threshold of 1.5 degrees Celsius. "On average, global temperatures in 2023 were 1.48 degrees Celsius higher than pre-industrial times," reports the Associated Press. "If annual averages reach above 1.5 degrees Celsius, the effects of global warming could become irreversible, climate scientists say." From the report: The record heat made life miserable and sometimes deadly in Europe, North America, China and many other places last year. But scientists say a warming climate is also to blame for more extreme weather events, like the lengthy drought that devastated the Horn of Africa, the torrential downpours that wiped out dams and killed thousands in Libya and the Canada wildfires that fouled the air from North America to Europe. In a separate Tuesday press event, international climate scientists who calculate global warming's role in extreme weather, the group's leader, Imperial College climate scientist Friederike Otto said "we definitely see in our analysis the strong impact of it being the hottest year."

The World Weather Attribution team only looks at events that affect at least 1 million people or kill more than 100 people. But Otto said her team was overwhelmed with more than 160 of those in 2023, and could only conduct 14 studies, many of them on killer heat waves. "Basically every heat wave that is occurring today has been made more likely and is hotter because of human-induced climate change," she said. [....] Antarctic sea ice hit record low levels in 2023 and broke eight monthly records for low sea ice, Copernicus reported.

Copernicus calculated that the global average temperature for 2023 was about one-sixth of a degree Celsius (0.3 degrees Fahrenheit) warmer than the old record set in 2016. While that seems a small amount in global record-keeping, it's an exceptionally large margin for the new record, [Copernicus Deputy Director Samantha Burgess] said. Earth's average temperature for 2023 was 14.98 degrees Celsius (58.96 degrees Fahrenheit), Copernicus calculated.

According to Bloomberg, Apple's AirDrop feature has been cracked by a Chinese state-backed institution to identify senders who share "undesirable content". MacRumors reports: AirDrop is Apple's ad-hoc service that lets users discover nearby Macs and iOS devices and securely transfer files between them over Wi-Fi and Bluetooth. Users can send and receive photos, videos, documents, contacts, passwords and anything else that can be transferred from a Share Sheet. Apple advertises the protocol as secure because the wireless connection uses Transport Layer Security (TLS) encryption, but the Beijing Municipal Bureau of Justice (BMBJ) says it has devised a way to bypass the protocol's encryption and reveal identifying information.

According to the BMBJ's website, iPhone device logs were analyzed to create a "rainbow table" which allowed investigators to convert hidden hash values into the original text and correlate the phone numbers and email accounts of AirDrop content senders. The "technological breakthrough" has successfully helped the public security authorities identify a number of criminal suspects, who use the AirDrop function to spread illegal content, the BMBJ added. "It improves the efficiency and accuracy of case-solving and prevents the spread of inappropriate remarks as well as potential bad influences," the bureau added.

It is not known if the security flaw in the AirDrop protocol has been exploited by a government agency before now, but it is not the first time a flaw has been discovered. In April 2021, German researchers found that the mutual authentication mechanism that confirms both the receiver and sender are on each other's address book could be used to expose private information. According to the researchers, Apple was informed of the flaw in May of 2019, but did not fix it.

As General Motors prepares to roll out electric versions of its Buicks, "hundreds of Buick dealerships nationwide" are "turning their backs on the storied brand," reports the Boston Globe.

"The move to electric Buicks is one reason so many dealers are giving up their Buick franchises, according to auto industry watchers." They say that smaller, low-volume Buick dealers either can't or won't make the big investments needed to begin selling EVs, especially as sales growth in the sector has cooled and unsold electrics are piling up on dealer lots. "I think there are dealers who are just not confident in the electric vehicle transition and they don't want to have to commit to the investment," said Karl Brauer, executive analyst at online car retailer iSeeCars.com...

Buick has announced its intention to migrate to an all-electric line of cars by the end of the decade. The brand's first EV is set to go on sale this year. But getting ready to sell EVs is a costly proposition. Dealers must purchase new equipment to service the cars and must pay for worker retraining. GM estimates that the upfront cost to dealers will range between $200,000 and $400,000. "If you're in a market where you're not selling a lot of Buicks, investing a lot to sell electric Buicks may not make a good business case," said Mark Schirmer, spokesperson for Cox Automotive, an Atlanta-based automotive marketing company.
While 854,000 Buicks were sold in 1980, just 103,000 were sold in 2022 — down from 207,000 in 2019, according to the article. So in 2022 GM bought out 44 percent of its dealerships (which they say accounted for just 20% of all U.S. Buick sales), with the majority of them still selling other GM brands like Chevrolet and GMC.

But the article also includes some perspective from Robert O'Koniewski, executive vice president of the Massachusetts State Automobile Dealers Association. "The only reason GM has kept the Buick alive is that it's popular in China." That's Buick's biggest market by far, thanks to a 50-50 joint venture it launched in 1997 with government-owned SAIC Motor, China's biggest carmaker. The partnership sold 653,000 Chinese Buicks in 2022.

But that's a big decline from the 926,000 sold in 2020. Brauer said that Chinese consumers are pulling away from the US brand in favor of Chinese companies like BYD, which passed Tesla in the fourth quarter of 2023 to become the world's largest maker of electric vehicles.

Long-time Slashdot reader xetdog shared this report from IEEE Spectrum: High in the Andes mountains where the borders of Argentina, Bolivia, and Chile intersect, white expanses of salt stretch for thousands of kilometers. Under these flats lie reservoirs of brine that contain upwards of 58% of the world's lithium. For decades, producers have extracted that lithium by pumping the water up to the surface and letting it evaporate until the lithium salts become concentrated enough to filter out. The process takes 12 to 18 months, leaving behind piles of waste containing other metals. It also evaporates nearly 2 million liters of local water resources, harming indigenous communities.

To keep up, many companies are now developing processes to chemically or physically filter out lithium from brines and inject the brine back underground. These direct lithium extraction (DLE) technologies take hours instead of months and could double the production of lithium from existing brine operations. Much as shale extraction did for oil, DLE is a "potential game-changing technology for lithium supply," because it could unlock new sources of lithium, according to a recent report by Goldman Sachs. But in contrast to shale's fracking risks, DLE brings environmental benefits, reducing land and water use, and waste...

In China, a handful of commercial projects already use Chinese DLE innovator Sunresin's technology.
More than 12 startups are pursuing new DLE processes, according to the article, "with the intent of commercial production as early as 2025."

And America's Department of Energy is also investing millions of dollars in new DLE tech "to extract lithium from geothermal brines in the U.S., such as the Salton Sea in California, which the National Renewable Energy Laboratory estimates could provide over 24,000 metric tons of lithium a year."

Huawei's newest laptop runs on a chip made by Taiwan Semiconductor Manufacturing Co., a teardown of the device showed, quashing talk of another Chinese technological breakthrough. From a report: The Qingyun L540 notebook contains a 5-nanometer chip made by the Taiwanese company in 2020, around the time US sanctions cut off Huawei's access to the chipmaker, research firm TechInsights found after dismantling the device for Bloomberg News. That counters speculation that Huawei's mainland Chinese chipmaking partner, Semiconductor Manufacturing International Corp., may have achieved a major leap in fabrication technique.

Huawei caused a stir in the US and China last August when it released a smartphone with a 7nm processor made by Shanghai-based SMIC. A teardown by the Canada-based research outfit for Bloomberg News showed the Mate 60 Pro's chip was only a few years behind the cutting edge, a feat that US trade curbs were meant to prevent. That revelation spurred celebration across the Chinese tech scene, and a debate in the US about the effectiveness of sanctions.
