Long-time Slashdot reader schwit1 shared this report from Futurism: China has unveiled an extremely powerful "hypergravity machine" that can generate forces almost two thousand times stronger than Earth's regular gravity.

The futuristic-looking machine, called CHIEF1900, was constructed at China's Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) at Zheijang University in Eastern China, and allows researchers to study how extreme forces affect various materials, plants, cells, or other structures, as the South China Morning Post reports... [Once up and running, it will allow researchers to recreate "catastrophic events such as dam failures and earthquakes inside a laboratory, according to the university."] For instance, it can analyze the structural stability of an almost 1,000-feet-tall dam by spinning a ten-foot model at 100 Gs, meaning 100 times the Earth's regular gravity. It could also be used to study the resonance frequencies of high-speed rail tracks, or how pollutants seep into soil over thousands of years.

The machine officially dethroned its predecessor, CHIEF1300, which became the world's most powerful centrifuge a mere four months ago... It can generate 1,900 g-tonnes of force, or 1,900 times the Earth's gravity. To put that into perspective, a washing machine only reaches about two g-tonnes.

European satellite operator Eutelsat "plans to launch 440 Airbus-built LEO satellites in the coming years to replenish and expand its constellation," Reuters reported Friday. And last week America's Federal Communications Commission approved SpaceX's request to deploy another 7,500 Starlink satellites, while Starlink "projects it will eventually have a constellation of 34,000 satellites," writes Fast Company, and Amazon's Project Leo "plans to launch more than 3,200 satellites."

Meanwhile "Beijing and some Chinese companies are planning two separate mega-constellations, Guowang and G60 Starlink, totaling nearly 26,000 satellites," and this week the Chinese government "applied for launch permits for 200,000 satellites."

But a small Texas-based company called AST SpaceMobile "believes it can provide better service with fewer than 100 gigantic satellites in space." AST SpaceMobile has developed a direct-to-cell technology that utilizes large satellites called BlueBirds. These machines use thousands of antennas to deliver broadband coverage directly to standard mobile phones, says the company's president, Scott Wisniewski. "This approach is remarkably efficient: We can achieve global coverage with approximately 90 satellites, not thousands or even tens of thousands required by other systems," Wisniewski writes in an email...

The key is its satellites' size and sophistication. AST's first generation of commercial satellite, the BlueBird 1-5, unfolds into a massive 693-square-foot array in space. Today, the company has five operational BlueBird 1-5 satellites in orbit, but its ambitions are much bigger. On December 24, 2025, AST launched the first of its next-generation satellites from India — called Block 2 — and this one broke records. The BlueBird 6 has a surface of almost 2,400 square feet, making it the largest single satellite in low Earth orbit. The company plans to launch up to 60 more by the end of 2026. "This large surface area is essential for gathering faint signals from standard, unmodified mobile phones on the ground," Wisniewski explains. It is essentially a single, extremely powerful and sensitive cell tower in the sky, capable of serving a huge geographical area...

To be clear, AST SpaceMobile's approach is not without its own controversies. The sheer size of the company's satellites makes them incredibly bright in the night sky, a significant source of frustration for ground-based astronomers. McDowell confirms that when it launched in 2022, AST's prototype satellite, BlueWalker 3, became "one of the top 10 brightest objects in the night sky for a while."

"It's a serious issue, and we are working directly with the astronomy community to mitigate our impact," Wisniewski says. The company is exploring solutions like anti-reflective coatings and operational adjustments to minimize the time its satellites are at maximum brightness...
AST SpaceMobile has already proven its technology works, the article points out, with six working satellites now transmitting at typical 5G speeds directly to regular phones.

Friday a federal judge "cleared U.S. power company Dominion Energy to resume work on its Virginia offshore wind project." But a U.S. federal judge also ruled Thursday that another major offshore wind farm is allowed to resume construction, reports the Hill. "The project, which would supply power to New York, was one of five that were halted by the Trump administration in December...."

In fact, there were three different court rulings this week each allowing construction to continue on a U.S. wind project: Judge Carl Nichols, a Trump appointee, granted a preliminary injunction allowing Empire Wind to keep building... Another, Revolution Wind, was also allowed to move forward in court this week... The project would provide enough power for up to 500,000 homes, according to its website. The court's decision allows construction to resume while the underlying case against the Trump order plays out.
Meanwhile, power company Orsted "is also suing over the pause of its Sunrise Wind project for New York," reports the Associated Press, "with a hearing still to be set." The fifth paused project is Vineyard Wind, under construction in Massachusetts. Vineyard Wind LLC, a joint venture between Avangrid and Copenhagen Infrastructure Partners, joined the rest of the developers in challenging the administration on Thursday.
CNN points out that the Vineyard Wind project "has been allowed to send power to the grid even amid Trump's suspension, a spokesperson for regional grid operator ISO-New England told CNN in an email." Residential customers in the mid-Atlantic region, including Virginia, desperately need more energy to service the skyrocketing demand from data centers â" and many are seeing spiking energy bills while they wait for new power to be brought online.
CNN notes that president Trump said last week "My goal is to not let any windmill be built; they're losers."

The Associated Press adds that "In contrast to the halted action in the US, the global offshore wind market is growing, with China leading the world in new installations. Nearly all of the new electricity added to the grid in 2024 was renewable. The British government said on Wednesday it had secured a record 8.4 gigawatts of offshore wind in Europe's largest offshore wind auction, enough clean electricity to power more than 12m homes."

An anonymous reader quotes a report from the Guardian: Even low levels of common agricultural pesticides can stunt the long-term lifespan of fish, according to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana. Signs of aging accelerated when fish were exposed to the chemicals, according to the study, published in Science, which could have implications for other organisms. [...] The research found that fish from pesticide-affected lakes showed shortened telomeres, the caps at the end of chromosomes that are known as the biological clock for aging. When they shorten, it is a sign of cellular aging and a decline in the body's regenerative capacity. The lake populations consisted of younger fish, indicating that the pesticides contributed to shortened lives. Laboratory experiments confirmed the findings and showed chronic low-dose exposure reduced fish survival and degraded telomeres. These effects were not seen with acute high-dose exposure.

Chemical analysis showed chlorpyrifos, which is banned in the UK and the EU but used in the US and China, was the only compound found in the fish tissues that was consistently associated with signs of aging. These included shortened telomeres and lipofuscin deposition -- a buildup of insoluble proteins often described as cellular "junk". The worrying aging effects occurred at concentrations below current US freshwater safety standards, Rohr said, suggesting the effects of chemicals and pesticides could be occurring at low levels over the long term. While short-term exposure to high doses did not appear to cause these aging issues -- though it did cause high toxicity and death in fish -- the researchers concluded that it was long-term exposure to low doses that drove the changes. The scientists added that reduced lifespan was particularly problematic because older fish often contribute disproportionately to reproduction, genetic diversity and population stability.

Longtime Slashdot reader hackingbear shares a report from the Washington Times: Breaking with the United States, Canada has agreed to cut its 100% tariff [back to 6.1%] on Chinese electric cars in return for lower tariffs on Canadian farm products, Prime Minister Mark Carney said Friday after meeting Chinese President Xi Jinping in Beijing. He said there would be an initial annual cap of 49,000 vehicles on Chinese EV exports to Canada, growing to about 70,000 over five years. Prior to the 100% tariff, China exported about 41,000 vehicles to Canada in 2023. In exchange, China will reduce its total tariff on canola seeds, a major Canadian export, from 84% to about 15%, he told reporters. Carney said China has become a more predictable partner to deal with than the U.S, the country's neighbor and longtime ally.

[hackingbear writes: "After helping the U.S. arrest Huawei CFO Meng Wanzhou, who was later released without admitting guilty by the Biden administration after bickering with China, Canada had followed the U.S. in putting tariffs of 100% on EVs from China and 25% on steel and aluminum under former Prime Minister Justin Trudeau, Carney's predecessor."] China responded by imposing duties of 100% on Canadian canola oil and meal and 25% on pork and seafood. It added a 75.8% tariff on canola seeds last August. Collectively, the import taxes effectively closed the Chinese market to Canadian canola, an industry group has said.

An anonymous reader shares a report: China is pulling the plug on a key advantage held by high-frequency traders, removing servers dedicated to those firms out of local exchanges' data centers, according to people familiar with the matter.

Commodities futures exchanges in Shanghai and Guangzhou are among those that have ordered local brokers to shift servers for their clients out of data centers run by the bourses, according to the people, who said the move was led by regulators. The change doesn't only affect high-frequency firms but they are likely to feel the biggest impact. The Shanghai Futures Exchange has told brokers they need to get equipment for high-speed clients out by the end of next month, while other clients need to do so by April 30, the people said.

The clampdown will hit China's army of domestic high-frequency firms but will also impact a swathe of global firms that are active in the country. Citadel Securities, Jane Street Group and Jump Trading are among the foreign firms whose access to servers is being affected, the people said, asking not to be named as the matter is private.

Go, the ancient board game that China, Japan and South Korea all claim as part of their cultural heritage, is struggling to expand its global footprint because the three nations that dominate it cannot agree on something as basic as a common rulebook.

When Go was registered with the International Mind Sports Association alongside chess and bridge, organizers had to adopt the American Go Association's rules because the East Asian trio failed to reach consensus. In 2025, China's Ke Jie withdrew from a title match at a Seoul tournament after receiving repeated penalties for violating a rule that the South Korean Go association had introduced mid-tournament. China's Go association responded by barring foreign players, most of them South Korean, from its domestic competitions.

It also doesn't help that the game's commercial appeal is fading. Japan's Nihon Ki-in, the country's main Go association, has started exploring a potential sale of its Tokyo headquarters. Young people across the region are gravitating toward chess, shogi, and video games instead.

The U.S. has approved limited sales of Nvidia's H200 AI chips to China, the Department of Commerce said on Tuesday. Exports will be allowed to "approved customers" with security safeguards and a 25% U.S. government cut. The company's most advanced Blackwell chips will remain restricted. The BBC reports: The H200, Nvidia's second-most-advanced semiconductor, had been restricted by Washington over concerns that it would give China's technology industry and military an edge over the U.S. The Commerce Department said the chips can be shipped to China granted that there is sufficient supply of the processors in the U.S.

Nvidia's spokesperson told the BBC that the company welcomed the move, saying it will benefit manufacturing and jobs in the U.S. The Commerce Department's Bureau of Industry and Security said its revised export policy applies to Nvidia's H200 chips, as well as less advanced processors. Chinese customers must also show "sufficient security procedures" and cannot use the chips for military uses.

Chinese embassy spokesman Liu Pengyu told the BBC on Wednesday that Beijing has consistently opposed the "politicization and weaponization of tech and trade issues." "We oppose blocking and restricting China, which disrupts the stability of industrial and supply chains," he said. "This approach does not serve the common interests of both sides."

An anonymous reader shares a report: Chinese authorities have told domestic companies to stop using cybersecurity software made by roughly a dozen firms from the U.S. and Israel due to national security concerns, two people briefed on the matter said.

As trade and diplomatic tensions flare between China and the U.S. and both sides vie for tech supremacy, Beijing has been keen to replace Western-made technology with domestic alternatives. The U.S. companies whose cybersecurity software has been banned include Broadcom-owned VMware, Palo Alto Networks and Fortinet, while the Israeli companies include Check Point Software Technologies, the sources said.

Coal power generation fell in China and India for the first time since the 1970s last year, in a "historic" moment that could bring a decline in global emissions, according to analysis. From a report: The simultaneous fall in coal-powered electricity in the world's biggest coal-consuming countries had not happened since 1973, according to analysts at the Centre for Research on Energy and Clean Air, and was driven by a record roll-out of clean energy projects.

The research, commissioned by the climate news website Carbon Brief, found that electricity generated by coal plants fell by 1.6% in China and by 3% in India last year, after the boom in clean energy across both countries was more than enough to meet their rising demand for energy. China added more than 300GW of solar power and 100GW of wind power last year -- together, more than five times the UK's total existing power generation capacity -- which are both "clear new records for China and, therefore, for any country ever," the report said. India added 35GW of solar, 6GW of wind and 3.5GW of hydropower last year, according to the analysis.

Prosecutors in Taiwan issued an arrest warrant [non-paywalled source] for the chief executive officer of the Chinese smartphone company OnePlus, stepping up the island's efforts to block China's tech players from recruiting Taiwanese talent. From a report: The Shilin district prosecutors office issued the warrant for CEO and co-founder Pete Lau and indicted two Taiwanese citizens who worked for him, according to an indictment by the office. OnePlus, a niche player whose phones run on a customized version of Android, is suspected of illegally recruiting more than 70 engineers in Taiwan.

The autonomous territory has stepped up its efforts to stop Chinese companies from raiding workers, who are often coveted because of their technical knowledge and experience. The Taiwanese officials put such limitations in place because they say recruiting from the semiconductor sector and other tech operations could jeopardize national security.

The viral Chinese app Are You Dead? (known as Sileme in Chinese) targets people who live alone by requiring regular check-ins and alerting an emergency contact if the user doesn't respond. It launched in May and is now the most downloaded paid app in China. Cybernews reports: Users need to check in with the app every two days by clicking a large button to confirm that they are alive. Otherwise, the app will inform the user's appointed emergency contact that they may be in trouble, Chinese state-run outlet Global Times reports. The app is marketed as a "safety companion" for those who live far from home or choose a solitary lifestyle.

Initially launched as a free app, "eAre You Dead?" now costs 8 yuan, equivalent to $1.15. Despite its growing popularity, the app has sparked criticism in China, where some said they were repulsed by the negative connotation of death. Some suggested the app should be renamed to "Are You Alive?" The app's creators told Chinese media that they will focus on improving the product, such as adding SMS notification features or a messaging function. Moreover, they will consider the criticism over the app's name.

An anonymous reader shares a report: Deserts are hard to reclaim because plants cannot survive on shifting sand, but scientists in northwest China are changing that -- by dropping vast amounts of blue-green algae onto the dry terrain. These specially selected strains of cyanobacteria can survive extreme heat and drought for long periods, according to China Science Daily on Thursday. When rain finally comes, they spring to life, spreading rapidly and forming a tough, biomass-rich crust over the sand. This living layer stabilises the dunes and creates the perfect foundation for future plant growth.

This is the first time in human history that microbes are being used on a massive scale to reshape natural landscapes. As the "Great Green Wall" -- China's massive multi-decade initiative to plant trees and fight desertification -- expands to include efforts in Africa and Mongolia, the unprecedented geoengineering technology could one day transform the face of our planet. This artificial "crusting" technique was developed by scientists at a research station in Ningxia Hui autonomous region, located in northwest China on the edge of the Tengger Desert, according to China Science Daily.

"China recently placed a supercritical carbon dioxide power generator into commercial operation," writes CleanTechnica, "and the announcement was widely framed as a technological breakthrough." The system, referred to as Chaotan One, is installed at a steel plant in Guizhou province in mountainous southwest China and is designed to recover industrial waste heat and convert it into electricity. Each unit is reported to be rated at roughly 15 MW, with public statements describing configurations totaling around 30 MW. Claimed efficiency improvements range from 20% to more than 30% higher heat to power conversion compared with conventional steam based waste heat recovery systems. These are big numbers, typical of claims for this type of generator, and they deserve serious attention.

China doing something first, however, has never been a reliable indicator that the thing will prove durable, economic, or widely replicable. China is large enough to try almost everything. It routinely builds first of a kind systems precisely because it can afford to learn by doing, discarding what does not work and scaling what does. This approach is often described inside China as crossing the river by feeling for stones. It produces valuable learning, but it also produces many dead ends. The question raised by the supercritical CO2 deployment is not whether China is capable of building it, but whether the technology is likely to hold up under real operating conditions for long enough to justify broad adoption.

A more skeptical reading is warranted because Western advocates of specific technologies routinely point to China's limited deployments as evidence that their preferred technologies are viable, when the scale of those deployments actually argues the opposite. China has built a single small modular reactor and a single experimental molten salt reactor, not fleets of them, despite having the capital, supply chains, and regulatory capacity to do so if they made economic sense... If small modular reactors or hydrogen transportation actually worked at scale and cost, China would already be building many more of them, and the fact that it is not should be taken seriously rather than pointing to very small numbers of trials compared to China's very large denominators...

What is notably absent from publicly available information is detailed disclosure of materials, operating margins, impurity controls, and maintenance assumptions. This is not unusual for early commercial deployments in China. It does mean that external observers cannot independently assess long term durability claims.
The article notes America's Energy Department funded a carbon dioxide turbine in Texas rated at roughly 10 MW electric that "reached initial power generation in 2024 after several years of construction and commissioning." But for both these efforts, the article warns that "early efficiency claims should be treated as provisional. A system that starts at 15 MW and delivers 13 MW after several years with rising maintenance costs is not a breakthrough. It is an expensive way to recover waste heat compared with mature steam based alternatives that already operate for decades with predictable degradation..."

"If both the Chinese and U.S. installations run for five years without significant reductions in performance and without high maintenance costs, I will be surprised. In that case, it would be worth revisiting this assessment and potentially changing my mind."

Scifi author/tech activist Cory Doctorow has decried the "enshittification" of our technologies to extract more profit. But Saturday he also described what could be "the beginning of the end for enshittification" in a new article for the Guardian — "our chance to make tech good again". There is only one reason the world isn't bursting with wildly profitable products and projects that disenshittify the US's defective products: its (former) trading partners were bullied into passing an "anti-circumvention" law that bans the kind of reverse-engineering that is the necessary prelude to modifying an existing product to make it work better for its users (at the expense of its manufacturer)...

Post-Brexit, the UK is uniquely able to seize this moment. Unlike our European cousins, we needn't wait for the copyright directive to be repealed before we can strike article 6 off our own law books and thereby salvage something good out of Brexit... Until we repeal the anti-circumvention law, we can't reverse-engineer the US's cloud software, whether it's a database, a word processor or a tractor, in order to swap out proprietary, American code for robust, open, auditable alternatives that will safeguard our digital sovereignty. The same goes for any technology tethered to servers operated by any government that might have interests adverse to ours — say, the solar inverters and batteries we buy from China.

This is the state of play at the dawn of 2026. The digital rights movement has two powerful potential coalition partners in the fight to reclaim the right of people to change how their devices work, to claw back privacy and a fair deal from tech: investors and national security hawks. Admittedly, the door is only open a crack, but it's been locked tight since the turn of the century. When it comes to a better technology future, "open a crack" is the most exciting proposition I've heard in decades.

"Scientists in China have made a breakthrough with fusion energy that could finally overcome one of the most stubborn barriers to realising the next-generation energy source," reports the Independent: A team from the Chinese Academy of Sciences (CAS) said its experimental nuclear reactor, dubbed the 'artificial Sun', achieved a plasma density that was previously thought impossible... Through a new process called plasma-wall self organisation, the CAS researchers were able to keep the plasma stable at unprecedented density levels. By pushing plasma density well past long-standing empirical limits, the researchers said fusion ignition can be achieved with far higher energy outputs. "The findings suggest a practical and scalable pathway for extending density limits in tokamaks and next-generation burning plasma fusion devices," said Professor Ping Zhu from Huazhong University of Science and Technology, who so-led the research.

Professor Zhu's team now plan to apply this new method on the EAST reactor to confirm that it will work under high-performance plasma conditions. The latest breakthrough was detailed in the journal Science Advances in a study titled 'Accessing the density-free regime with ECRH-assisted ohmic start-up on EAST'.

China has hacked the emails used by congressional staff on powerful committees in the US House of Representatives, as part of a massive cyber espionage campaign known as Salt Typhoon. An anonymous reader shares a report: Chinese intelligence accessed email systems used by some staffers [non-paywalled source] on the House China committee in addition to aides on the foreign affairs committee, intelligence committee and armed services committee, according to people familiar with the attack. The intrusions were detected in December.

The attacks are the latest element of an ongoing cyber campaign against US communication networks by the Ministry of State Security, China's intelligence service. One person familiar with the attack said it was unclear if the MSS had accessed lawmakers' emails. The MSS has been operating Salt Typhoon for several years. It allows China to access the unencrypted phone calls, texts and voicemails of almost every American, and in some cases enables access to email accounts. Salt Typhoon has also intercepted the calls of senior US officials over the past couple of years, said people familiar with the campaign.

A new working paper from researchers at the University of Hong Kong has found that Chinese graduate students who plagiarized more heavily in their master's theses were significantly more likely to pursue careers in the civil service and to climb the ranks faster once inside.

John Liu and co-authors analyzed 6 million dissertations from CNKI, a Chinese academic repository, and cross-referenced them against public records of civil-service exam-takers to identify 120,000 civil servants and their academic work. Those who entered the public sector had plagiarism scores 15.6% above average. Customs and tax officials fared worst -- their scores ran 25% and 26% higher than private-sector peers respectively. Within the civil service, those who plagiarized more were promoted 9% faster during the first five years of their careers. The researchers validated their plagiarism metric through an experiment involving 443 job applicants who were asked to roll dice for rewards without monitoring. Those who had plagiarized more also reported improbably high rolls.

Samsung's co-CEO TM Roh has warned that product price increases are "inevitable" as an unprecedented global memory chip shortage squeezes margins across the company's consumer electronics lineup -- from smartphones to televisions and home appliances.

The South Korean giant, one of the top two largest smartphone manufacturers, plans to double the number of mobile devices running its Galaxy AI features to 800 million units this year, up from 400 million at the end of 2025. Galaxy AI is powered by Google's Gemini model and Samsung's own Bixby assistant for different tasks. "As this situation is unprecedented, no company is immune to its impact," Roh told Reuters in his first interview since becoming co-CEO in November.

Samsung is working with partners on longer-term strategies to minimize the impact, he said. Market researchers IDC and Counterpoint predict the global smartphone market will shrink this year as the chip shortage threatens to drive up phone prices. The shortage is a boon to Samsung's semiconductor business but pressures margins on its smartphone division, the company's second-largest revenue source.

The New York Times checks in on U.S. university researchers and start-ups trying to create domestic rare-earth processing facility: There is too little money to be made in rare earths for the elements to be of much interest to mining giants, so the challenge of reestablishing a domestic industry has fallen to small companies like Phoenix Tailings, a Boston-area startup that runs the metal-making plant in Exeter, New Hampshire. A handful of other companies in the United States are processing rare earths in small quantities, including MP Materials, which owns a mine in Mountain Pass, California, and recently began producing rare-earth metal in Fort Worth, Texas. Similar efforts are underway in Europe and Asia. "It's small volumes of low-value materials that are very expensive to process," said Elsa Olivetti, a materials science and engineering professor at the Massachusetts Institute of Technology. "Meaning it's hard to make money."

Phoenix Tailings' New Hampshire operation is about 2 months old, housed in a converted medical device plant. The company buys metric-ton bags of powder — a mixture of neodymium and praseodymium bound with oxygen — from mining and refining companies in the United States, South America and Australia. It funnels that flour-like material into a drying oven and eventually into furnaces that heat it to the temperature of volcanic lava. This circuit takes up less than 15,000 square feet and is designed to generate no emissions other than those associated with the electricity Phoenix Tailings uses. The closed-loop design distinguishes this process from the more energy-intensive techniques used in China, where workers scoop up molten metal with ladles. That approach releases perfluorocarbons, potent greenhouse gases that do not break down easily.
In late 2024 the company was three weeks from bankruptcy — but it's recently been valued at $189 million.
