Even Central Banks Are Losing Faith in CBDCs (ft.com) 31

Central bank support for digital currencies appears to have fallen sharply, with only 13% of central bankers surveyed by OMFIF Digital Monetary Institute backing CBDCs as a cross-border payment solution, down from 31% in 2023.

The survey found just 10% of respondents are actively developing CBDCs, compared with 21% last year. The decline comes despite major initiatives including the Bank for International Settlements' Project Agora and China's Project mBridge. The BIS recently withdrew from mBridge, creating a potential split between Western and emerging market payment systems. Nearly half of surveyed bankers favor improving existing instant payment infrastructure over CBDCs.

Plastics Lobbyists Make Up Biggest Group at Vital UN Treaty Talks (theguardian.com) 34

Record numbers of plastic industry lobbyists are attending global talks that are the last chance to hammer out a treaty to cut plastic pollution around the world. From a report: The key issue at the conference will be whether caps on global plastic production will be included in the final UN treaty. Lobbyists and leading national producers are furiously arguing against any attempt to restrain the amount that can be produced, leaving the talks on a knife-edge.

New analysis by the Center for International Environmental Law (CIEL) shows 220 fossil fuel and chemical industry representatives -- more plastic producers than ever -- are represented at the UN talks in Busan, South Korea. Taken as a group, they would be the biggest delegation at the talks, with more plastic industry lobbyists than representatives from the EU and each of its member states, (191) or the host country, South Korea (140), according to the Centre for International Environmental Law. Their numbers overwhelm the 89 delegates from the Pacific small island developing states (PSIDs), countries that are among those suffering the most from plastic pollution.

Sixteen lobbyists from the plastics industry are at the talks as part of country delegations. China, the Dominican Republic, Egypt, Finland, Iran, Kazakhstan and Malaysia all have industry vested interests within their delegations, the analysis shows. The plastic producer representatives outnumber delegates from the Scientists' Coalition for an Effective Plastics Treaty by three to one. Approximately 460m tonnes of plastics are produced annually, and production is set to triple by 2060 under business-as-usual growth rates.

Philippines Recruits Civilian Tech Talent To Fend Off Cyber Attacks (restofworld.org) 11

The Philippine Army is recruiting civilian hackers to bolster its cybersecurity defenses amid rising digital threats from China, army officials said. The 120-member Cyber Battalion has hired 70 tech experts in their 20s and 30s since 2020, offering them military training and the opportunity to serve the nation despite lower wages than private sector jobs.

The initiative follows cyber attacks on Philippine government servers, including those of the Coast Guard and President Marcos Jr., which authorities traced to China. Beijing denies involvement. The Philippines ranks among the countries most vulnerable to cyber threats, with recent attacks compromising millions of citizens' data through state and private institutions.

China Woos Western Tech Talent in Race for Chip Supremacy (msn.com) 82

Chinese companies are aggressively recruiting foreign tech talent as a key strategy to gain technological supremacy, prompting national security concerns across Western nations and Asia, WSJ reported Wednesday, citing multiple intelligence officials and corporate sources. The campaign focuses particularly on advanced semiconductor expertise, with companies like Huawei offering triple salaries to employees at critical firms like Zeiss SMT and ASML, which produce essential components for cutting-edge chip manufacturing.

These recruitment efforts intensified after Western export controls restricted China's access to advanced technology. While Taiwan and South Korea have implemented strict countermeasures, including criminal penalties for illegal talent transfers, the U.S. and Europe struggle to balance open labor markets with national security concerns.

Chinese firms often obscure their origins through local ventures and persistent recruitment tactics. The strategy has shown results: Former employees have helped Chinese companies advance their technological capabilities, including SMIC's development of 7nm chips with help from ex-TSMC talent.

Singapore Emerges as Key Testing Ground for Autonomous Vehicles (restofworld.org) 12

Singapore is positioning itself as a key testing ground for autonomous vehicles, attracting major Chinese firms and establishing unified national guidelines that contrast with fragmented regulations in the U.S. and China.

China's WeRide launched the country's first public autonomous bus service on Sentosa island in June, while multiple companies are deploying self-driving vehicles for logistics and transportation. The controlled rollout aligns with Singapore's strategy to address labor shortages and land constraints.

Singapore topped KPMG's Autonomous Vehicles Readiness Index, with companies citing its political neutrality and stringent safety standards as major draws for testing operations.

Qualcomm Reportedly Loses Interest In Intel Takeover 51

Qualcomm's interest in acquiring Intel is cooling due to the complexity of the deal, Intel's debt, and regulatory hurdles. However, according to Bloomberg, Qualcomm may still explore acquiring certain divisions of Intel to expand into markets like PCs and networking. Tom's Hardware reports: [T]he proposed acquisition faced significant obstacles, including Intel's $50 billion debt, dropping CPU market share, and its struggling semiconductor manufacturing unit, an area where Qualcomm lacks expertise. A deal of this magnitude would also likely trigger extensive regulatory scrutiny, particularly in China, a key market for both companies.

Intel is undergoing significant restructuring under CEO Pat Gelsinger to reclaim its competitiveness in the semiconductor market in terms of products and process technologies. Still, for now, both Intel and Qualcomm are quite successful standalone companies. While the combination would make a formidable firm (probably facing unprecedented antitrust scrutiny), it does not make much sense for Qualcomm to make such a massive takeover. These factors have collectively made a complete takeover less appealing to Qualcomm. Meanwhile, selling off a part of the company to Qualcomm may not make sense for Intel.

Qualcomm aims to generate $22 billion in annual revenue by 2029 by expanding into markets like personal computers, networking, and automotive chips. Although Cristiano Amon, Qualcomm's chief executive, has stated that his company did not need a major takeover to achieve this goal, the company initiated preliminary discussions with Intel regarding a potential acquisition in September. Yet, it does not look like the deal is going to happen.

Huawei's Mate 70 Smartphones Will Run Its New Android-Free OS (theverge.com) 80

An anonymous reader quotes a report from The Verge: Huawei has announced its new Mate 70 series smartphone lineup, which will be the first offered with the company's new HarmonyOS Next operating system that doesn't rely on Google's Android services and won't run any Android apps, according to a report by Reuters. The four models of the Mate 70 also don't feature any US hardware following a half decade of US sanctions.

The Mate 70, Mate 70 Pro, Mate 70 Pro Plus, and Mate 70 RS will also be offered with Huawei's HarmonyOS 4.3, which first launched in August 2019 as an alternative to Google's Android OS and is still compatible with Android's extensive app library. Users who decide to opt for Huawei's new Android-free HarmonyOS Next will have less choice when it comes to the apps they can install. Huawei says it has "secured more than 15,000 applications for its HarmonyOS ecosystem, with plans to expand to 100,000 apps in the coming months," according to Reuters.

Starting next year, Huawei also says all the new phones and tablets it launches in 2025 will run HarmonyOS Next. [...] Huawei hasn't confirmed what processors are being used in the Mate 70 lineup, but the company has previously used chips made by China's SMIC for last year's Mate 60 series and other smartphones.

US To Reportedly Sanction 200 More Chinese Chip Firms (tomshardware.com) 82

The U.S. is preparing to impose new sanctions targeting 200 Chinese chipmakers and potentially restricting the export of High Bandwidth Memory (HBM). The move is intended to further hinder China's semiconductor and AI advancements. Tom's Hardware reports: The update sheds light on the Biden administration's recent efforts to impose stricter regulations on chip manufacturers in China. The latest swarm of sanctions reportedly targets roughly 200 Chinese firms. US companies are prohibited from exporting select technologies or products to the targeted firms. The report suggests that the US Department of Commerce aims to push these new regulations before the Thanksgiving break - or November 28. Neither the Department of Commerce nor the Chamber of Commerce responded to Reuters' request for comments.

Moreover, another wave of sanctions is set to follow in December - targeting the export of HBM (High Bandwidth Memory) - primarily to choke China's advance in the AI domain. The impacts of these restrictions are materializing given that Huawei's Kirin SoCs and Ascend AI accelerators will reportedly remain stuck at 7nm technology until 2026 as SMIC fails to procure cutting-edge Extreme Ultraviolet (EUV) machines from ASML.

Apple's Upcoming Ultra-Slim iPhone Hits Roadblock Over SIM Tray Rules 118

Apple's upcoming slim iPhone model faces potential sales obstacles in China due to design limitations that prevent fitting a physical SIM card tray, which is mandatory in the Chinese market.

The new device, planned for release next fall, measures 5-6 millimeters thick compared to the iPhone 16's 7.8mm, The Information reported Monday [non-paywalled source]. The company aims to revitalize iPhone sales in China, where revenue has declined for three consecutive years amid competition from Huawei and Vivo. The thin iPhone relies on embedded SIMs (eSIMs), which Chinese regulators haven't yet approved for smartphone use. Engineers are also struggling with battery placement and thermal management in the slim design, the report added.

World Agrees on $300B Climate Aid Financial Deal - After COP29 Summit 'Nearly Implodes' (cnn.com) 120

"At points there was fear the talks would implode, as groups representing vulnerable small island states and the least-developed countries walked out of negotiations Saturday," according to a new report from CNN.

But after weeks of international climate talks at COP29, "the world agreed to a new climate deal... "with wealthy countries pledging to provide $300 billion annually by 2035 to poorer countries to help them cope with the increasingly catastrophic impacts of the climate crisis." The amount pledged, however, falls far short of the $1.3 trillion economists say is needed to help developing countries cope with a climate crisis they have done least to cause — and there has been a furious reaction from many developing countries. a fiery speech immediately after the gavel went down, India's representative Chandni Raina slammed the $300 billion as "abysmally poor" and a "paltry sum," calling the agreement "nothing more than an optical illusion" and unable to "address the enormity of the challenge we all face."

Others were equally damning in their criticism. We are leaving with a small portion of the funding climate-vulnerable countries urgently need," said Tina Stege, Marshall Islands climate envoy. Stege heavily criticized the talks as showing the "very worst of political opportunism." Fossil fuel interests "have been determined to block progress and undermine the multilateral goals we've worked to build," she said in a statement...

There was also a push for richer emerging economies such as China and Saudi Arabia to contribute to the climate funding package, but the agreement only "encourages" developing countries to make voluntary contributions, and places no obligations on them... Saudi Arabia, the world's top oil exporter, which has pushed against ambitious action at past climate summits, seemed even more emboldened in Baku, publicly and explicitly rejecting any reference to oil, coal and gas in the deal.

The package "is also being criticised as short-sighted from the richer world's perspective," notes the BBC: The argument runs that if you want to keep the world safe from rising temperatures, then wealthier nations need to help emerging economies cut their emissions, because that is where 75% of the growth in emissions has occurred in the past decade.
But "Delegations more optimistic about the agreement said this deal is headed in the right direction," writes the Associated Press, "with hopes that more money flows in the future." The text included a call for all parties to work together using "all public and private sources" to get closer to the $1.3 trillion per year goal by 2035. That means also pushing for international mega-banks, funded by taxpayer dollars, to help foot the bill. And it means, hopefully, that companies and private investors will follow suit on channeling cash toward climate action. The agreement is also a critical step toward helping countries on the receiving end create more ambitious targets to limit or cut emissions of heat-trapping gases.

China Wiretaps Americans in 'Worst Hack in Our Nation's History' (gizmodo.com) 91

Longtime Slashdot reader mspohr shares a report from Gizmodo: Hackers for the Chinese government were able to deeply penetrate U.S. telecommunications infrastructure in ways that President Joe Biden's administration hasn't yet acknowledged, according to new reports from the Washington Post and New York Times. The hackers were able to listen to phone calls and read text messages, reportedly exploiting the system U.S. authorities use to wiretap Americans in criminal cases. The worst part? The networks are still compromised and it may take incredibly drastic measures to boot them from U.S. systems.

The hackers behind the infiltration of U.S. telecom infrastructure are known to Western intelligence agencies as Salt Typhoon, and this particular breach of U.S. equipment was first reported in early October by the Wall Street Journal. But Sen. Mark Warner, a Democrat from Virginia, spoke with the Washington Post and New York Times this week to warn the public that this is so much worse than we initially thought, dubbing it "the worst telecom hack in our nation's history." And those articles based on Warner's warnings were published late Thursday.

Hackers weren't able to monitor or intercept anything encrypted, according to the Times, which means that conversations over apps like Signal and Apple's iMessage were probably protected. But end-to-end encryption over texts between Apple devices and Android devices, for instance, aren't encrypted in the same way, meaning they were vulnerable to interception by Salt Typhoon, according to the Times. The details about how the hackers were able to push so deeply into U.S. systems are still scarce, but it has something to do with the ways in which U.S. authorities wiretap suspects in this country with a court order.

Baidu's Supercheap Robotaxis Should Scare the Hell Out of the US (theverge.com) 93

Baidu's new Apollo Go robotaxi brings significant advances in affordability and scalability that should make U.S. competitors like Waymo a bit nervous, according to The Verge's Andrew J. Hawkins. From the report: The RT6 is the sixth generation of Apollo Go's driverless vehicle, which made its official debut in May 2024. It's a purpose-built, Level 4 autonomous vehicle, meaning it's built without the need for a human driver. And here's the thing that should make US competitors nervous: adopting a battery-swapping solution, the price for one individual RT6 is "under $30,000," Baidu CEO Robin Li said in an earnings call. "All the strengths just mentioned above are driving us forward, paving the way to validate our business model," Li added. [...]

We still don't know the net effect of Baidu's cost improvements. But bringing down the upfront cost of each individual vehicle to below $30,000 will go a long way toward improving the company's unit economics, in which each vehicle brings in more money than it costs. There are still a lot of outstanding costs to consider, such as hardware depreciation and fleet maintenance, but from what Baidu is signaling, things are on the right track. From the looks of it, the company is passing those savings along to its customers. Base fares start as low as 4 yuan (around 55 cents), compared with 18 yuan (around $2.48) for a taxi driven by a human, according to state media outlet Global Times. Apollo Go said it has provided 988,000 rides across all of China in Q3 2024 -- a year-over-year growth of 20 percent. And cumulative public rides reached 8 million in October.

China Overtakes Germany and Japan In Robot Density (reuters.com) 38

China has overtaken Germany and Japan in terms of robot density, according to an annual report by the International Federation of Robotics (IFR). Reuters reports: South Korea is the world leader with 1,012 robots per 10,000 employees, up 5% since 2018, said the IFR. Singapore comes next, followed by China with 470 robots per 10,000 workers - more than double the density it had in 2019. That compares with 429 per 10,000 employees in Germany, which has had an annual growth rate of 5% since 2018, said IFR.

The Growth Rate For Mobile Internet Subscribers Has Stalled Across the World (restofworld.org) 41

An anonymous reader shares a report: A recent survey from Global System for Mobile Communications Association Intelligence (GSMA), the research wing of a U.K.-based organization that represents mobile operators around the world, found that 4.6 billion people across the globe are now connected to mobile internet -- or roughly 57% of the world's population. Now, the rate of new mobile internet subscriber growth is slowing. From 2015 to 2021, the survey consistently found over 200 million coming online through mobile devices around the world each year. But in the last two years, that number has dropped to 160 million.

Rest of World analysis of that data found that a number of developing countries are plateauing in the number of mobile internet subscribers. That suggests that in countries like Pakistan, Bangladesh, Nigeria, and Mexico, the easiest populations to get online have already logged on, and getting the rest of the population on mobile internet will continue to be a challenge. GSMA collects data by surveying a nationally representative sample of people in each country, and then it correlates the results with similar studies.

[...] In countries including China, the U.S., and Singapore, a high share of the population is already connected to mobile internet -- 80%, 81%, and 93%, respectively. So it's no surprise that the rate of mobile internet subscriptions has slowed. But the rate of new users has also slowed in countries including Bangladesh, Nigeria, and Pakistan -- where only 37%, 34%, and 24% of the population currently use mobile internet.

Z-Library Helps Students to Overcome Academic Poverty, Study Finds (torrentfreak.com) 41

A new study reveals that many users, particularly students and Redditors, view Z-Library as a vital resource for overcoming economic barriers to education, reflecting a "Robin Hood" mentality that prioritizes access to knowledge over copyright concerns. TorrentFreak reports: The research looks at the motivations of two groups; Reddit users and Chinese postgraduate students. Despite the vast differences between these groups, their views on Z-Library are quite similar. The 134 Reddit responses were sampled from the Zlibrary subreddit, which is obviously biased in favor of the site. However, the reasoning goes well beyond a simple "I want free stuff" arguments. Many commenters highlighted that they were drawn to the site out of poverty, for example, or they highlighted that Z-Library was an essential tool to fulfill their academic goals.

"Living in a 3rd world country, 1 book would cost like 50%- 80% already of my daily wage," one Redditor wrote. The idea that Z-Library is a 'necessary evil' was also highlighted by other commenters. This includes a student who can barely make ends meet, and a homeless person, who has neither the money nor the space for physical books. The lack of free access to all study materials, including academic journal subscriptions at university libraries, was also a key motivator. Paired with the notion that journal publishers make billions of dollars, without compensating authors, justification is found for 'pirate' alternatives. "They make massive profits. So stealing from them doesn't hurt the authors nor reviewers, just the rich greedy publishers who make millions just to design a cover and click 'publish'," one Redditor wrote.

The second part of the study is conducted in a more structured format among 103 postgraduate students in China. This group joined a seminar where Z-Library and the crackdown were discussed. In addition, the students participated in follow-up focus group discussions, while also completing a survey. Despite not all being users of the shadow library, 41% of the students agreed that the site's (temporary) shutdown affected their ability to study and find resources for degree learning. In general, the students have a favorable view toward Z-Library and similar sites, and 71% admit that they have used a shadow library in the past. In line with China's socialist values, the overwhelming majority of the students agreed that access to knowledge should be free for everyone. While the students are aware of copyright law, they believe that the need to access knowledge outweighs rightsholders' concerns. This is also reflected in the following responses, among others. All in all, Z-Library and other shadow libraries are seen as a viable option for expensive or inaccessible books, despite potential copyright concerns.
The paper has been published in the Journal of University Teaching & Learning Practice.

China Activates World's Most Advanced Hypergravity Facility (interestingengineering.com) 23

China has activated the world's most advanced hypergravity machine to advance studies in geological processes, material behavior, and deep-sea energy exploration. Located in Hangzhou, The Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) will be able to produce forces thousands of times stronger than Earth's gravity. Interesting Engineering reports: The facility will house three primary hypergravity centrifuges and 18 onboard units. These centrifuges, machines designed to spin containers rapidly, force heavier materials to the edges or bottom by creating hypergravity conditions, as reported by the South China Morning Post (SCMP). The first centrifuge's main engine, resembling two massive arms holding experimental baskets, has been installed. According to the Hangzhou government, the fabrication of the remaining two centrifuges and 10 onboard units is underway.

[...] CHIEF will surpass the capabilities of the US Army Corps of Engineers' hypergravity facility, which has a capacity of 1,200 g-t (gravity acceleration x ton). Once completed, CHIEF will feature a capacity of 1,900 g-t, making it the most advanced facility of its kind, reports SCMP. The project includes six hypergravity experiment chambers, each dedicated to a specific area, such as slope and dam engineering, seismic geotechnics, deep-sea exploration, deep-earth studies, geological processes, and materials processing.

China Population Set for 51 Million Drop as Pro-Birth Moves Fail (bloomberg.com) 259

An anonymous reader shares a report: China's population is expected to shrink by 51 million -- more than the size of California -- over the next decade as policymakers struggle to reverse the country's falling birth rate, according to Bloomberg Intelligence. By 2035, the population is expected to drop to 1.36 billion, levels not seen since 2012, down from a peak of 1.41 billion in 2021, BI senior industry analyst Ada Li estimates.

There could be a temporary spike in births in 2024 as the Year of the Dragon is considered an auspicious time to have children. But past single-year surges in birth rates have been short-lived, and this year may be no exception, especially with marriage rates at an all-time low, Li said. China faces a looming population crisis, with the United Nations projecting it could shrink to half its current size by 2100.

Carbon Emissions Continued Increasing Last Year, Especially in China and India - But Not the US (apnews.com) 222

An anonymous reader shared this report from the Associated Press: Even as Earth sets new heat records, humanity this year is pumping 330 million tons (300 million metric tons) more carbon dioxide into the air by burning fossil fuels than it did last year. This year the world is on track to put 41.2 billion tons (37.4 billion metric tons) of the main heat-trapping gas into the atmosphere. It's a 0.8% increase from 2023, according to Global Carbon Project, a group of scientists who track emissions... This year's pollution increase isn't quite as large as last year's 1.4% jump, scientists said while presenting the data at the United Nations climate talks in Azerbaijan...

The continued rise in carbon emissions is mostly from the developing world and China. Many analysts had been hoping that China — by far the world's biggest annual carbon polluting nation with 32% of the emissions — would have peaked its carbon dioxide emissions by now. Instead China's emissions rose 0.2% from 2023, with coal pollution up 0.3%, Global Carbon Project calculated... [Although its growth rate now is "basically flat," O'Sullivan said.] That's nothing close to the increase in India, which at 8% of the globe's carbon pollution is third-largest carbon emitter. India's carbon pollution jumped 4.6% in 2024, the scientists said.

Carbon emissions fell 0.6% in the U.S. mostly from reduced coal, oil and cement use. The U.S. was responsible for 13% of the globe's carbon dioxide in 2024. Historically, it's responsible for 21% of the world's emissions since 1950... Twenty-two nations have shown steady decreases in emissions, O'Sullivan said, singling out the United States as one of those. The biggest emission drops from 2014 to 2023 were in the United States, Japan, Germany, the United Kingdom and Ukraine. Europe, which accounts for 7% of the world's carbon pollution, saw its carbon dioxide output drop 3.8% from last year — driven by a big cut in coal emissions.

Some interesting statistics from the article:
  • Burning coal, oil, and natural gas is currently emitting 2.6 million pounds (1.2 million kilograms) of carbon dioxide every second..."
  • In the last 10 years, emissions have gone up about 6%.
  • Global carbon emissions are more than double what they were 50 years ago, and 50% more than they were in 1999.

"If the world continues burning fossil fuels at today's level, it has six years before passing 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, the limit agreed to at the 2015 climate talks in Paris, said study co-author Stephen Sitch. The Earth is already at 1.3 degrees Celsius (2.3 Fahrenheit), according to the United Nations."

Yet "Total carbon emissions — which include fossil fuel pollution and land use changes such as deforestation — are basically flat because land emissions are declining, the scientists said."

Samples Obtained By Chinese Spacecraft Show Moon's Ancient Volcanism (yahoo.com) 31

China's Chang'e-6 mission made history by retrieving the first surface samples from the moon's far side, revealing evidence of volcanic activity spanning 1.4 billion years. Reuters reports: Researchers said on Friday the soil brought back from the Chang'e-6 landing site contained fragments of volcanic rock - basalt - dating to 4.2 billion years ago and to 2.8 billion years ago. This points to a long period of volcanic activity - at least 1.4 billion years - on the far side during the first half of the moon's history, when it was a more dynamic world than it is today. The moon, like Earth, formed about 4.5 billion years ago. Volcanism on the moon, Earth and other planetary bodies involves the eruption of molten rock from the mantle - the layer just under the outer crust - onto the surface. The landing site in the South Pole-Aitken Basin, an impact crater, is an area with the thinnest crust on the moon, helpful for finding evidence of volcanism.

The samples contained various volcanic rock fragments, and the researchers used a method called radioisotope dating to determine their age. Lunar basalt samples previously were obtained from the moon's near side, which perpetually faces Earth, during U.S. Apollo, Soviet Luna and Chinese Chang'e-5 missions. These showed that volcanism on the near side had occurred as long ago as 4.0 billion years ago and continued for at least two billion years, Li said. "The exact timing and duration of lunar volcanism is elusive and maybe varied across different regions. Some small-scale volcanism may have also occurred on the near side as late as about 120 million years ago as recorded by volcanic glass beads from Chang'e-5 samples" collected in 2020, Li said.

The new study also found that the basalt dating to 4.2 billion years ago differed in composition from the basalt dating to 2.8 billion years ago, meaning they originated from different sources of molten rock - magma - in the mantle, Li said. The Chang'e-6 samples, Li said, also differ in composition compared with previously collected lunar samples from the near side.
