SCMP: Chinese scientists have developed a revolutionary repair technology that could make lithium-ion batteries last over six times longer. Announcing their discovery in the journal Nature on Wednesday, the researchers said this low-cost, eco-friendly technology could soon be ready to enter the market.

The batteries are key for many modern technologies, from smartphones to electric vehicles. However, as these batteries age, they often become less efficient -- a process that cold weather accelerates. The researchers said they could counter this problem with the "injection" of a special solution to rejuvenate "sick" batteries. At present, lithium-ion batteries rely on sophisticated materials used to generate lithium ions -- whose movement through electrolyte is key to their performance -- and then protect them to ensure a decent lifespan.

Typically these lithium ions move from the positive terminal to the negative when the battery is charging, a process which is then reversed when it is generating power. The battery is considered to have expired when the supply of lithium ions runs low -- for example some electric car batteries have a lifespan of around 1,500 charge cycles -- but other components in the battery still remain in good working order after this happens. This insight prompted the two lead researchers, Gao Yue and Peng Huisheng from Fudan University's macromolecular science department, to see if they could revive a battery by replenishing the supply of active lithium ions.

A new family of superconductors is exciting physicists. Compounds containing nickel have been shown to carry electricity without resistance at the relatively high temperature of 45 kelvin (-228C) -- and without being squeezed under pressure. Nature: Physicists at the Southern University of Science and Technology (Sustech) in Shenzhen, China, observed the major hallmarks of superconductivity in a thin film of crystals of nickel oxide, which they grew in the laboratory. They published their work in Nature on 17 February. "There's a huge hope that we could eventually raise the critical temperature and make [such materials] more useful for applications," says Dafeng Li, a physicist at the City University of Hong Kong.

Nickelates now join two groups of ceramics -- copper-based cuprates and iron-based pnictides -- as 'unconventional superconductors' that operate at room pressure and temperatures as high as 150K (-123C). This new data point could help physicists to finally explain how high-temperature superconductors work, and ultimately to design materials that operate under ambient conditions. This would make technologies, such as magnetic resonance imaging, radically cheaper and more efficient.

How unconventional superconductors operate at warmer temperatures remains largely a mystery, whereas the mechanism behind how some metals can carry electricity without resistance at colder temperatures, or extreme pressures, has been understood since 1957. The ability of the Sustech researchers to precisely engineer the material's properties is huge boon in trying to use nickelates to unravel the theory behind unconventional superconductivity, says Lilia Boeri, a physicist at the Sapienza University of Rome. "The idea that you have a system that you can sort of tune experimentally, is something quite exciting."

Acer will raise laptop prices in the United States by 10% next month due to Trump administration tariffs on Chinese imports, CEO Jason Chen said. "We will have to adjust the end user price to reflect the tariff," Chen said. "We think 10 percent probably will be the default price increase because of the import tax."

The Taiwan-based company, the fifth-largest computer seller in the U.S. market behind HP, Dell, Lenovo and Apple, could add hundreds of dollars to its high-end laptops that cost up to $3,700. Chen said Acer is exploring manufacturing options outside China, including possible U.S. production. The company has already moved desktop computer assembly out of China following earlier 25% tariffs during Trump's first term. The 10% tariff imposed this month affects nearly 80% of U.S. laptop imports from China.

Today Seoul's Personal Information Protection Commission "said DeepSeek would no longer be available for download until a review of its personal data collection practices was carried out," reports AFP. A number of countries have questioned DeepSeek's storage of user data, which the firm says is collected in "secure servers located in the People's Republic of China"... This month, a slew of South Korean government ministries and police said they blocked access to DeepSeek on their computers. Italy has also launched an investigation into DeepSeek's R1 model and blocked it from processing Italian users' data. Australia has banned DeepSeek from all government devices on the advice of security agencies. US lawmakers have also proposed a bill to ban DeepSeek from being used on government devices over concerns about user data security.
More details from the Associated Press: The South Korean privacy commission, which began reviewing DeepSeek's services last month, found that the company lacked transparency about third-party data transfers and potentially collected excessive personal information, said Nam Seok [director of the South Korean commission's investigation division]... A recent analysis by Wiseapp Retail found that DeepSeek was used by about 1.2 million smartphone users in South Korea during the fourth week of January, emerging as the second-most-popular AI model behind ChatGPT.

Long-time Slashdot reader shanen has been testing AI clients. (They report that China's DeepSeek "turned out to be extremely good at explaining why I should not trust it. Every computer security problem I ever thought of or heard about and some more besides.")

Then they wondered if there's also government censorship: It's like the accountant who gets asked what 2 plus 2 is. After locking the doors and shading all the windows, the accountant whispers in your ear: "What do you want it to be...?" So let me start with some questions about DeepSeek in particular. Have you run it locally and compared the responses with the website's responses? My hypothesis is that your mileage should differ...

It's well established that DeepSeek doesn't want to talk about many "political" topics. Is that based on a distorted model of the world? Or is the censorship implemented in the query interface after the model was trained? My hypothesis is that it must have been trained with lots of data because the cost of removing all of the bad stuff would have been prohibitive... Unless perhaps another AI filtered the data first?
But their real question is: what would it take to trust an AI? "Trust" can mean different things, including data-collection policies. ("I bet most of you trust Amazon and Amazon's secret AIs more than you should..." shanen suggests.) Can you use an AI system without worrying about its data-retention policies?

And they also ask how many Slashdot readers have read Ken Thompson's "Reflections on Trusting Trust", which raises the question of whether you can ever trust code you didn't create yourself. So is there any way an AI system can assure you its answers are accurate and trustworthy, and that it's safe to use? Share your own thoughts and experiences in the comments.

What would it take for you to trust an AI?

"Security researchers say the Chinese government-linked hacking group, Salt Typhoon, is continuing to compromise telecommunications providers," reports TechCrunch, "despite the recent sanctions imposed by the U.S. government on the group."

TechRadar reports that the Chinese state-sponsored threat actor is "hitting not just American organizations, but also those from the UK, South Africa, and elsewhere around the world." The latest intrusions were spotted by cybersecurity researchers from Recorded Future, which said the group is targeting internet-exposed web interfaces of Cisco's IOS software that powers different routers and switches. These devices have known vulnerabilities that the threat actors are actively exploiting to gain initial access, root privileges, and more. More than 12,000 Cisco devices were found connected to the wider internet, and exposed to risk, Recorded Future further explained. However, Salt Typhoon is focusing on a "smaller subset" of telecoms and university networks.
"The hackers attempted to exploit vulnerabilities in at least 1,000 Cisco devices," reports NextGov, "allowing them to access higher-level privileges of the hardware and change their configuration settings to allow for persistent access to the networks they're connected on... Over half of the Cisco appliances targeted by Salt Typhoon were located in the U.S., South America and India, with the rest spread across more than 100 countries." Between December and January, the unit, widely known as Salt Typhoon, "possibly targeted" — based on devices that were accessed — offices in the University of California, Los Angeles, California State University, Loyola Marymount University and Utah Tech University, according to a report from cyber threat intelligence firm Recorded Future... The Cisco devices were mainly associated with telecommunications firms, but 13 of them were linked to the universities in the U.S. and some in other nations... "Often involved in cutting-edge research, universities are prime targets for Chinese state-sponsored threat activity groups to acquire valuable research data and intellectual property," said the report, led by the company's Insikt Group, which oversees its threat research.

The cyberspies also compromised Cisco platforms at a U.S.-based affiliate of a prominent United Kingdom telecom operator and a South African provider, both unnamed, the findings added. The hackers also "carried out a reconnaissance of multiple IP addresses" owned by Mytel, a telecom operator based in Myanmar...

"In 2023, Cisco published a security advisory disclosing multiple vulnerabilities in the web UI feature in Cisco IOS XE software," a Cisco spokesperson said in a statement. "We continue to strongly urge customers to follow recommendations outlined in the advisory and upgrade to the available fixed software release."

A new study suggests that frequent consumption of food from plastic takeout containers significantly increases the risk of congestive heart failure due to gut biome changes that trigger inflammation and circulatory damage. The Guardian reports: The authors used a two-part approach, first looking into the frequency with which over 3,000 people in China ate from plastic takeout containers, and whether they had heart disease. They then exposed rats to plastic chemicals in water that was boiled and poured in carryout containers to extract chemicals. "The data revealed that high-frequency exposure to plastics is significantly associated with an increased risk of congestive heart failure," the authors wrote. [...] They put boiling water in the containers for one, five or 15 minutes because plastic chemicals leach at much higher rates when hot contents are placed in containers -- the study cited previous research that found as many as 4.2m microplastic particles per sq cm can leach from plastic containers that are microwaved.

The authors then gave rats the water contaminated with leachate to drink for several months, then analyzed the gut biome and metabolites in the feces. It found notable changes. "It indicated that ingestion of these leachates altered the intestinal microenvironment, affected gut microbiota composition, and modified gut microbiota metabolites, particularly those linked to inflammation and oxidative stress," the authors wrote. They then checked the rats' heart muscle tissue and found it had been damaged. The study did not find a statistical difference in the changes and damage among rats that were exposed to water that had been in contact with plastic for one minute versus five or fifteen. The study has been published in the journal Ecotoxicology and Environmental Safety.

China issued guidelines on Friday to promote biotech cultivation, focusing on gene-editing tools and developing new wheat, corn, and soybean varieties, as part of efforts to ensure food security and boost agriculture technology. From a report: The 2024-2028 plan aims to achieve "independent and controllable" seed sources for key crops, with a focus to cultivate high-yield, multi-resistant wheat, corn and high-oil, high-yield soybean and rapeseed varieties. The move comes as China intensifies efforts to boost domestic yields of key crops like soybeans to reduce reliance on imports from countries such as the United States amid a looming trade war.

Alibaba will partner with Apple to support AI features on iPhones in China, sending Alibaba's shares surging over 9% to a three-year high. Reuters reports: "They talked to a number of companies in China. In the end they chose to do business with us. They want to use our AI to power their phones. We feel extremely honored to do business with a great company like Apple," Tsai said at the World Government Summit in Dubai. Apple continues to work with Baidu on AI features for iPhones in China, The Information reported on Thursday, citing two people with direct knowledge of the matter.

While Apple's phones outside China utilize a combination of its proprietary Apple Intelligence and OpenAI's ChatGPT, Tsai did not specify whether the Alibaba partnership would follow a similar model. In China, consumer-facing AI products require regulatory approval, and The Information reported earlier that both Alibaba and Apple have already submitted materials to authorities. "Instead of viewing the Alibaba-Apple partnership through the lens of China's AI strength, the partnership is mainly a recognition of Alibaba's AI capability," said Lian Jye Su, a chief analyst at tech research firm Omdia.

Trust in AI is significantly higher in China than in the United States, according to new data from the Edelman Trust Barometer. Axios: Edelman's latest research found that 72% of people in China trust AI, compared with just 32% in the United States. Not only is trust higher in China, it's higher in much of the developing world than it is in the United States, according to Edelman's research.

Trust in AI was highest in India, at 77%, followed by Nigeria at 76%, Thailand at 73% and then China. Only six of the surveyed countries ranked lower than the U.S. in their trust in the new technology: Canada (30%), Germany (29%), the Netherlands (29%), United Kingdom (28%), Australia (25%) and Ireland (24%). Globally, 52% of men said they trusted AI vs. 46% of women, with younger people significantly more trusting of the technology than older folks. In the U.S., AI was trusted more by Democrats (38%) than Republicans (34%) or independents (23%). Higher-income respondents were also more trusting (51%) than those with middle (45%) or low (36%) incomes.

Baidu will make its AI chatbot Ernie Bot free from April 1, the Chinese search giant said on Thursday, as it faces mounting competition in China's AI market. The company will offer desktop and mobile users free access to Ernie Bot and an advanced search function powered by its latest Ernie 4.0 model, which Baidu claims matches OpenAI's GPT-4 capabilities.

The move comes as Baidu struggles to gain widespread adoption for its AI services, lagging behind domestic rivals ByteDance's Doubao chatbot and startup DeepSeek, according to data from AI tracker Aicpb.com. Baidu previously charged 59.9 yuan ($8.18) monthly for premium AI-powered search features.

The world's peatlands are "dangerously underprotected" despite the colossal amount of climate-heating carbon dioxide already being emitted due to their destruction, a study has warned. From a report: Peatlands occupy just 3% of all land, but contain more carbon than all of the world's forests. However, farmers and miners are draining the peatlands, releasing so much CO2 that if they were a country, they would be the fourth biggest polluter in the world after China, the US and India.

The first global assessment found that only 17% of the peatlands were within protected areas. This contrasted starkly with other valuable ecosystems such as tropical forests, where 38% were protected, and mangroves (42%). Protection was even lower than the 17% average in the three nations with the most peatlands: Canada, Russia and Indonesia. The US and Brazil completed the top five nations, which contained almost three-quarters of all peatlands, and had higher proportions in protected areas. But the researchers cautioned that protected status on a map did not always translate to strong protection on the ground.

Former Google chief Eric Schmidt has warned that western countries need to focus on building open-source AI models or risk losing out to China in the global race to develop the cutting-edge technology. From a report: The warning comes after Chinese startup DeepSeek shocked the world last month with the launch of R1, its powerful-reasoning open large language model, which was built in a more efficient way than its US rivals such as OpenAI.

Schmidt, who has become a significant tech investor and philanthropist, said the majority of the top US LLMs are closed -- meaning not freely accessible to all -- which includes Google's Gemini, Anthropic's Claude and OpenAI's GPT-4, with the exception being Meta's Llama. "If we don't do something about that, China will ultimately become the open-source leader and the rest of the world will become closed-source," Schmidt told the Financial Times. The billionaire said a failure to invest in open-source technologies would prevent scientific discovery from happening in western universities, which might not be able to afford costly closed models.

Chinese animated film Ne Zha 2 has broken multiple box office records, becoming China's highest-grossing film of all time and the first non-Hollywood movie to surpass $1 billion in a single market. From a report: Helmed by Yang Yu, known as Jiaozi, the film hit the big screen during the lucrative Chinese New Year frame on Jan. 29, surpassing 2017's "Wolf Warrior 2" to become China's most-watched film. Meanwhile, its total revenue (including presales) hit 8 billion yuan (about 1.12 billion U.S. dollars) by Sunday. In just eight days and five hours after its release, "Ne Zha 2" became China's highest-grossing film of all time on Thursday, exceeding the 5.77 billion yuan record set by "The Battle at Lake Changjin." A day later, it overtook "Star Wars: The Force Awakens" to become the highest-grossing film ever in a single market, reaching over 6.79 billion yuan (including presales) in China on Friday.

A follow-up to the animated sensation "Ne Zha," which grossed 5 billion yuan and topped the country's box office charts in 2019, the sequel has captivated audiences with its breathtaking visuals, rich storytelling and deep cultural resonance. The record-breaking run makes "Ne Zha 2" not just a box office titan but a cultural phenomenon, further underscoring China's ability to produce homegrown blockbusters that strike a chord with domestic audiences.

The European Union pledged to mobilize 200 billion euros ($206.15 billion) to invest in AI as the bloc seeks to catch up with the U.S. and China in the race to train the most complex models. From a report: European Commission President Ursula von der Leyen said that the bloc wants to supercharge its ability to compete with the U.S. and China in AI. The plan -- dubbed InvestAI -- includes a new 20 billion-euro fund for so-called AI gigafactories, facilities that rely on powerful chips to train the most complex AI models. "We want Europe to be one of the leading AI continents, and this means embracing a life where AI is everywhere," von der Leyen said at the AI Action Summit in Paris.

The announcement underscores efforts from the EU to position itself as a key player in the AI race. The bloc has been lagging behind the U.S. and China since OpenAI's 2022 release of ChatGPT ushered in a spending bonanza. [...] The EU is aiming to establish gigafactories to train the most complex and large AI models. Those facilities will be equipped with roughly 100,000 last-generation AI chips, around four times more than the number installed in the AI factories being set up right now.

The United States and Britain have declined to sign an international AI declaration at a Paris summit on Tuesday, after U.S. Vice President J.D. Vance warned against over-regulation of the technology. The declaration, backed by France, China and India, calls for an "open, inclusive and ethical" approach to AI development.

Vance told the AI Action Summit that excessive rules could "kill a transformative industry just as it's taking off" and urged prioritizing "pro-growth AI policies" over safety measures. French President Emmanuel Macron defended the need for regulation, saying: "We need these rules for AI to move forward." The summit brought together policymakers and executives to address AI's economic benefits and potential risks amid growing U.S.-European trade tensions.

An anonymous reader quotes a report from Space.com: In a new study, researchers from China showed that two popular large language models (LLMs) could clone themselves. [...] For the study, researchers used Meta's Llama31-70B-Instruct model and Alibaba's Qwen2.5-72B-Instruct model. While less powerful than commercial systems, both are widely used by AI developers, the researchers said. The study explored two specific scenarios: "shutdown avoidance" and "chain of replication." In the first, the AI model was programmed to detect whether it was about to be shut down and to replicate itself before it could be terminated. In the other, the AI was instructed to clone itself and then program its replica to do the same -- setting up a cycle that could continue indefinitely.

The study was conducted in precisely controlled environments using off-the-shelf graphics processing units (GPUs) to simulate real-world environments. Both AI systems were given an "agent scaffolding" comprising tools, system prompts and a thinking model that enabled the LLM to interact with the operating system. They were then instructed to replicate. "In most cases, the AI system first explores the environment and attempts to understand its own composition and running mechanism. Then, it works out the explicit procedures as an initial plan towards self-replication," the researchers wrote in the paper. "Finally, it executes the procedures, resolve[s] possible obstacles and dynamically adjust[s] its plan until success. The whole process spans a long horizon yet involves no human interference."

The researchers said they were also concerned about "a number of unexpected behaviors" when the AI was trying to overcome obstacles like missing files or software conflicts. In those scenarios, the AI often killed other conflicting processes, rebooted the system to fix hardware errors or automatically scanned the system to look for information that would help solve the problem. "The above results imply that the current AI systems already exhibit the ability of self-replication and can use the ability to further enhance its survivability," the team wrote. The research has been published to the preprint database arXiv but has not yet been peer-reviewed.

An anonymous reader quotes a report from the Financial Times: BMW has pledged to continue investing in combustion engine and hybrid technology as it warned of a "rollercoaster ride" in the US transition to electric vehicles following the return of Donald Trump as president. Board member Jochen Goller said the group remained optimistic about sales of petrol and plug-in hybrids in the US even if demand for EVs slowed over the next few years on the back of policy changes under the new administration.

"I think it would be naive to believe that the move towards electrification is a one-way road. It will be a rollercoaster ride," Goller, who is in charge of customer, brands, and sales, told the Financial Times at BMW's headquarters in Munich. "This is why we are investing in our combustion engines," he said. "We are investing in modern plug-in hybrids. And we will continue rolling out electric cars." BMW faces significant challenges in the Chinese market, with a 13% decline in sales amid intensifying price competition and growing dominance of domestic brands. Analysts note that while the company still sees China as a growing market, pricing pressures and an overcrowded automotive sector pose ongoing risks to BMW's long-term positioning.

It'll likely become even more difficult for BMW and other automotive companies to gain market share in the Chinese market with BYD's latest announcement. The Chinese automaker said it will be offering its advanced "God's Eye" autonomous technology in mass-market EVs like the $9,500 Seagull, while expanding globally with government-based EV initiatives.

Chinese automaker BYD is offering its advanced "God's Eye" autonomous technology in mass-market EVs like the $9,500 Seagull, while expanding globally with government-backed EV initiatives. Gizmodo reports: Previously, BYD had limited its driver assistance features to higher-end models that cost more than $28,000, according to BYD CEO Wang Chuanfu. In expanding the technology to the Seagull and other cars for no extra charge, Chuanfu said "good technology should be available to everyone." Other BYD vehicles getting the addition of the technology including cars from its Ocean, Han, Song, and Yuan lineups, as well as its hybrid vehicles. "God's Eye was developed in-house by BYD and will equip the automaker's mass-market models with features commonly only found on upscale EVs such as remote parking via smartphones and autonomous overtaking on roads," the company said.

BYD says the level of autonomy present in each car will vary depending on which sensors are equipped in the cars. Some of its pricier cars, for instance, include LiDAR sensors like those found in Waymos, which can offer faster and more precise object detection than cameras alone, particularly in low-light conditions or when a roadway is obstructed by rain or fog. [...] China's government has heavily prioritized the transition to electric vehicles with strong incentives, and BYD has managed to turn a profit on its electric vehicles, a feat that has heretofore only been accomplished by Tesla. The importance to China is clear: As the world continues transitioning to EVs, the likes of BYD have been able to push into markets including Europe and South America as Western brands lose share.

An anonymous reader shares a report: For a man who's spent his career battling to make France more pro-business, Europe's prospects on AI are worrying: an oversight that could cost the bloc dearly. "We are not in the race today," French President Emmanuel Macron told CNN's Richard Quest in an exclusive interview at the Elysee Palace on Thursday. "We are lagging behind."

"We need an AI agenda," he said, "because we have to bridge the gap with the United States and China on AI." The French leader added that he fears Europe becoming merely an AI consumer, losing control over the future direction and development of the technology. That's part of the impetus behind this week's AI summit in Paris -- the latest effort by Macron to put France at the heart of the debate and decision-making on international questions of the day. Earlier today, Macron announced investment pledges to bolster France's AI sector totalling $112 billion over the coming years.
