Researchers in Germany achieved a major milestone for the future quantum internet by successfully teleporting quantum information between photons generated by two different, physically separated quantum dots -- something never accomplished before due to the difficulty of producing indistinguishable photons from remote sources. Phys.org reports: At the University of Stuttgart, the team succeeded in teleporting the polarization state of a photon originating from one quantum dot to another photon from a second quantum dot. One quantum dot generates a single photon, the other an entangled photon pair. Entangled means that the two particles constitute a single quantum entity, even when they are physically separated. One of the two particles travels to the second quantum dot and interferes with its light particle. The two overlap. Because of this superposition, the information of the single photon is transferred to the distant partner of the pair. Instrumental for the success of the experiment were quantum frequency converters, which compensate for residual frequency differences between the photons. These converters were developed by a team led by Prof. Christoph Becher, an expert in quantum optics at Saarland University. [...] In the Stuttgart experiment, the quantum dots were separated only by an optical fiber of about 10 m length. "But we are working on achieving considerably greater distances," says Strobel. In earlier work, the team had shown that the entanglement of the quantum dot photons remains intact even after a 36-kilometer transmission through the city center of Stuttgart. Another aim is to increase the current success rate of teleportation, which currently stands at just over 70%. Fluctuations in the quantum dot still lead to slight differences in the photons. The findings have been published in the journal Nature Communications.

Today's representative line comes from Capybara James (most recently previously). It's representative, not just of the code base, but of Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. Or, "you get what you measure".

If, for example, you decide that code coverage metrics are how you're going to judge developers, then your developers are going to ensure that the code coverage looks great. If you measure code coverage, then you will get code coverage- and nothing else.

That's how you get tests like this:

Mockito.verify(exportRequest, VerificationModeFactory.atLeast(0)).failedRequest(any(), any(), any());

This test passes if the function exportRequest.failedRequest is called at least zero times, with any input parameters.

Which, as you might imagine, is a somewhat useless thing to test. But what's important is that there is a test. The standards for code coverage are met, the metric is satisfied, and Goodhart marks up another win on the board.

An anonymous reader quotes a report from the New York Times: When Mark Zuckerberg, Meta's chief executive, unveiled the company's Superintelligence Lab in June, he named 11 artificial intelligence researchers who were joining his ambitious effort to build a machine more powerful than the human brain. All 11 were immigrants educated in other countries. Seven were born in China, according to a memo viewed by The New York Times. Although many American executives, government officials and pundits have spent months painting China as the enemy of America's rapid push into A.I., much of the groundbreaking research emerging from the United States is driven by Chinese talent. Two new studies show that researchers born and educated in China have for years played major roles inside leading U.S. artificial intelligence labs. They also continue to drive important A.I. research in industry and academia, despite the Trump administration's crackdown on immigration and growing anti-China sentiment in Silicon Valley. The research, from two organizations, provides a detailed look at how much the American tech industry continues to rely on engineers from China, particularly in A.I. The findings also offer a more nuanced understanding of how researchers in the two countries continue to collaborate, despite increasingly heated language from Washington and Beijing.

Longtime Slashdot reader ukoda shares a report from the Associated Press: China is replacing its diesel trucks with electric models faster than expected, potentially reshaping global fuel demand and the future of heavy transport. In 2020, nearly all new trucks in China ran on diesel. By the first half of 2025, battery-powered trucks accounted for 22% of new heavy truck sales, up from 9.2% in the same period in 2024, according to Commercial Vehicle World, a Beijing-based trucking data provider. The British research firm BMI forecasts electric trucks will reach nearly 46% of new sales this year and 60% next year. China's trucking fleet, the world's second-largest after the U.S., still mainly runs on diesel, but the landscape is shifting. Transport fuel demand is plateauing, according to the International Energy Agency and diesel use in China could decline faster than many expect, said Christopher Doleman, an analyst at the Institute for Energy Economics and Financial Analysis. Electric trucks now outsell LNG models in China, so its demand for fossil fuels could fall, and "in other countries, it might never take off," he said. [...] The share of electrics in new truck sales, from 8% in 2024 to 28% by August 2025, has more than tripled as prices have fallen. Electric trucks outsold LNG-powered vehicles in China for five consecutive months this year, according to Commercial Vehicle World. While electric trucks are two to three times more expensive than diesel ones and cost roughly 18% more than LNG trucks, their higher energy efficiency and lower costs can save owners an estimated 10% to 26% over the vehicle's lifetime, according to research by Chinese scientists. "When it comes to heavy trucks, the fleet owners in China are very bottom-line driven," Doleman said.

A Tokyo court ruled that Cloudflare is liable for aiding manga piracy after failing to act on infringement notices and continuing to cache and serve content for major piracy sites, awarding about $3.2 million in damages. TorrentFreak says the decision sets a significant precedent in Japan, suggesting CDN providers can face direct liability when they don't verify customers or respond adequately to large-scale copyright abuse. From the report: After a wait of more than three and a half years, the Tokyo District Court rendered its decision this morning. In a statement provided to TorrentFreak by the publishers, they declare "Victory Against Cloudflare" after the Court determined that Cloudflare is indeed liable for the pirate sites' activities. In a statement provided to TorrentFreak, the publishers explain that they alerted Cloudflare to the massive scale of the infringement, involving over 4,000 works and 300 million monthly visits, but their requests to stop distribution were ignored. "We requested that the company take measures such as stopping the distribution of pirated content from servers under its management. However, Cloudflare continued to provide services to the manga piracy sites even after receiving notices from the plaintiffs," the group says. The publishers add that Cloudflare continued to provide services even after receiving information disclosure orders from U.S. courts, leaving them with "no choice but to file this lawsuit." "The judgment recognized that Cloudflare's failure to take timely and appropriate action despite receiving infringement notices from the plaintiffs, and its negligent continuation of pirated content distribution, constituted aiding and abetting copyright infringement, and that Cloudflare bears liability for damages to the plaintiffs," they write. "The judgment, in that regard, attached importance to the fact that Cloudflare, without conducting any identity verification procedures, had enabled a massive manga piracy site to operate "under circumstances where strong anonymity was secured,' as a basis for recognizing the company's liability." The publishers believe that the judgment clarifies the conditions under which a company such as Cloudflare incurs liability for copyright infringement. Failure to carry out identity verification appears at the top of the publishers' list, followed by a lack of timely and appropriate action in response to infringement notices sent by rightsholders. "We believe this is an important decision given the current situation where piracy site operators often hide their identities and repeatedly conduct large-scale distribution using CDN services from overseas. We hope that this judgment will be a step toward ensuring proper use of CDN services. We will continue our efforts to protect the rights of works, creators, and related parties, while aiming for further expansion of legitimate content," the publishers conclude. Cloudflare plans to appeal the verdict.

Adobe is buying Semrush for $1.9 billion in a move to supercharge its AI-driven marketing stack. Reuters reports: Semrush designs and develops AI software that helps companies with search engine optimization, social media and digital advertising. The acquisition, expected to close in the first half of next year, would allow Adobe to help marketers better understand how their brands are viewed by online consumers through searches on websites and generative AI bots such as ChatGPT and Gemini. "The price is steep as Semrush isn't a massive revenue engine on its own, so Adobe is likely paying for strategic value. The payoff could be high too if Adobe can quickly turn Semrush's data into monetizable AI products," said Emarketer analyst Grace Harmon. "While we are positive on Adobe restarting its M&A engine given the success that it has seen with this motion over the years... this deal likely does little to answer the questions revolving around the company's creative cloud business," added William Blair analysts.

An anonymous reader quotes a report from Ars Technica: This year's newest iPhones included one momentous change that marked a new phase in the evolution of Apple Silicon: the Apple N1, Apple's first in-house chip made to handle local wireless connections. The N1 supports Wi-Fi 7, Bluetooth 6, and the Thread smart home communication protocol, and it replaces the third-party wireless chips (mostly made by Broadcom) that Apple used in older iPhones. Apple claimed that the N1 would enable more reliable connectivity for local communication features like AirPlay and AirDrop but didn't say anything about how users could expect it to perform. But Ookla, the folks behind the SpeedTest app and website, have analyzed about five weeks' worth of users' testing data to get an idea of how the iPhone 17 lineup stacks up to the iPhone 16, as well as Android phones with Wi-Fi chips from Qualcomm, MediaTek, and others. While the N1 isn't at the top of the charts, Ookla says Apple's Wi-Fi chip "delivered higher download and upload speeds on Wi-Fi compared to the iPhone 16 across every studied percentile and virtually every region." The median download speed for the iPhone 17 series was 329.56Mbps, compared to 236.46Mbps for the iPhone 16; the upload speed also jumped from 73.68Mbps to 103.26Mbps. Ookla noted that the N1's best performance seemed to improve scores most of all in the bottom 10th percentile of performance tests, "implying Apple's custom silicon lifts the floor more than the ceiling." The iPhone 17 also didn't top Ookla's global performance charts -- Ookla found that the Pixel 10 Pro series slightly edges out the iPhone 17 in download speed, while a Xiaomi 15T Pro with MediaTek Wi-Fi silicon featured better upload speeds.

pbahra writes: Saudi Arabia is betting that the future of Hollywood won't be built in physical stages but in datacenters. In a push to anchor itself in next-generation film production, Riyadh-based Humain has led Luma AI's latest Series C round, backing the shift towards cloud-based, AI-generated video rather than traditional studio infrastructure.. Humain's announcement says the new investment will accelerate Luma's development of world models capable of learning from video, audio and language to generate photorealistic scenes, environments and characters on demand. Supporters argue this could upend film-making by pushing much of Hollywood's production pipeline into high-performance datacenters rather than physical sets.

Nvidia blew past earnings expectations with soaring revenue and profit, easing fears of an AI bubble and reinforcing its position as the engine of the global AI boom. From a report: Nvidia's sales grew 62% year-over-year to $57 billion in the October quarter, ahead of the $54.9 billion Wall Street had projected, signaling that demand for AI chips remains strong even as more questions emerge about whether returns from the technology will keep up with the pace of AI infrastructure investments. It posted profits of $31.9 billion, up 65% from the year-ago quarter and also slightly above expectations. "Blackwell sales are off the charts, and cloud GPUs are sold out," Nvidia CEO Jensen Huang said in a statement, a message that echoes his earlier arguments that fears of an AI bubble are overblown. The company also posted stronger-than-expected sales guidance of around $65 billion for the fourth quarter, another indicator that the AI spending spree isn't slowing anytime soon.

An anonymous reader quotes a report from Bloomberg: The Dutch government suspended its powers over chipmaker Nexperia, restoring control to its Chinese owner (paywalled; alternative source) and defusing a standoff with Beijing that had begun to hamper automotive production around the world. The order that gave the Netherlands powers to block or revise decisions at Nexperia was dropped as "a show of goodwill," Economic Affairs Minister Vincent Karremans said Wednesday in a post on social media site X. Bloomberg had reported earlier this month that the Netherlands was prepared to take the step if chip deliveries from the company's site in China could be confirmed. The move marks a significant de-escalation of a dispute that underscored the global nature of supply chains and highlighted Beijing's growing leverage. Even though Nexperia's chips aren't advanced and the company only operates one facility in China, the spat disrupted automakers from Honda Motor Co. to Volkswagen AG. The reversal by the Dutch government was set in motion after a breakthrough in talks earlier that involved Chinese and Dutch officials, with input from Germany, the European Union as well as the US. To help resolve the stalemate, Beijing agreed to loosen export restrictions from Nexperia's Chinese plant, the largest of its kind in the world. The Dutch economic affairs ministry sent a delegation to Beijing this week to negotiate a "mutually agreeable solution," according to a ministry statement.

An anonymous reader shares a report: This summer, Oslo's public-transport authority drove a Chinese electric bus deep into a decommissioned mine inside a nearby mountain to answer a question: Could it be hacked? Isolated by rock from digital interference, cybersecurity experts came back with a qualified yes: The bus could in theory be remotely disabled using the control system for the battery. The revelation, presented at a recent public-transport conference, has spurred officials in Denmark and the U.K. to start their own investigations into Chinese vehicles. It has also fed into broader security concerns across Europe about the growing prevalence of Chinese-made equipment in the region's energy and telecommunications infrastructure. The worry is the same for autos, solar panels and other connected devices: that mechanisms used for wirelessly delivering system updates could also be exploited by a hostile government or third-party hacker to compromise critical networks. [...] The Oslo transport authority, Ruter, said the bus's mobile-network connection via a Romanian SIM card gave manufacturer Yutong access to the control system for battery and power supply. Ruter said it is addressing the vulnerability by developing firewalls and delaying the signals sent to the vehicles, among other solutions.

A new treatment for tuberculosis could boost cure rates and shorten the time needed to treat the disease by months, trial results suggest. The Guardian: Globally, an estimated 10.7 million people fell ill with TB last year and 1.23 million died from it. In its annual report on tuberculosis, launched last week, the World Health Organization said it remained a "major global public-health problem" and the leading infectious cause of death. [...] Sorfequiline, a new antibiotic, showed stronger action against the deadly bacteria than existing treatments, with a comparable safety profile, researchers from the TB Alliance told the Union Conference on Lung Health in Copenhagen on Wednesday. The trial involved 309 people across 22 sites in South Africa, the Philippines, Georgia, Tanzania and Uganda, with different dose regimens. All participants had "drug-sensitive" tuberculosis, meaning a standard cocktail of drugs can safely treat them but researchers believe TB infections that are resistant to standard treatment could also be helped. The trial suggested a sorfequiline-based regimen could be used for anyone testing positive, said Dr Maria Beumont, vice-president of TB Alliance.

Action is needed now to reduce ultra-processed food (UPF) in diets worldwide because of their threat to health, say international experts in a global review of research. From a report: They say the way we eat is changing - with a move away from fresh, whole foods to cheap, highly-processed meals - which is increasing our risk of a range of chronic diseases, including obesity and depression. Writing in The Lancet, the researchers say governments need "to step up" and introduce warnings and higher taxes on UPF products, to help fund access to more nutritious foods. [...] This review of evidence on the impact of UPFs on health, carried out by 43 global experts and based on 104 long-term studies, suggests these foods are linked to a greater risk of 12 health conditions. These include type 2 diabetes, cardiovascular disease, kidney disease, depression and dying prematurely from any cause.

The EU's cookie consent policies have been an annoying and unavoidable part of browsing the web in Europe since their introduction in 2018. But the cookie nightmare is about to crumble thanks to some big proposed changes announced by the European Commission today. From a report: Instead of having to click accept or reject on a cookie pop-up for every website you visit in Europe, the EU is preparing to enforce rules that will allow users to set their preferences for cookies at the browser level. "People can set their privacy preferences centrally -- for example via the browser -- and websites must respect them," says the EU. "This will drastically simplify users' online experience." This key change is part of a new Digital Package of proposals to simplify the EU's digital rules, and will initially see cookie prompts change to be a simplified yes or no single-click prompt ahead of the "technological solutions" eventually coming to browsers. Websites will be required to respect cookie choices for at least six months, and the EU also wants website owners to not use cookie banners for "harmless uses" like counting website visits, to lessen the amount of pop-ups.

Linus Torvalds is "fairly positive" about vibe coding as a way for people to get computers to do things they otherwise could not. The Linux kernel maintainer made the comments during an interview at the Linux Foundation Open Source Summit in Seoul earlier this month. But he cautioned that vibe coding would be a "horrible, horrible idea from a maintenance standpoint" for production code. Torvalds told Dirk Hohndel, head of open source at Verizon, that computers have become more complicated than when he learned to code by typing in programs from computer magazines. He said vibe coding offers a path into computing for newcomers. The kernel maintainer is not using AI-assisted coding himself. He said his role has shifted from rejecting new ideas to sometimes pushing for them against opposition from longstanding maintainers who "kind of get stuck in a rut." Rust is "actually becoming a real part of the kernel instead of being this experimental thing," he said. Torvalds said AI crawlers have been "very disruptive to a lot of our infrastructure" because they gather data from kernel.org source code. Kernel maintainers receive bugs and security notices that are "made up by people who misuse AI," though the problem is smaller than for other projects such as curl.

Britain said on Wednesday it would ban the resale of tickets to concerts, sport and other live events for profit, disrupting ticket touts and the platforms that benefit from their activities. From a report: Culture Secretary Lisa Nandy said touts were ripping off fans by using bots to snap up batches of tickets for coveted shows and reselling them at sky-high prices. "Our new proposals will shut down the touts' racket and make world-class music, comedy, theatre and sport affordable for everyone," she said, after the government had promised action.

Chinese economist Gao Shanwen told a Washington panel in December that China's real GDP growth might be around 2% rather than the official figure near 5%. By January, Gao was no longer chief economist at SDIC Securities and went silent for almost a year. As FT points out in a long piece, China does not publish quarterly GDP breakdowns showing consumption, investment and net exports. Every other major economy produces these figures. The IMF in 2024 gave China a C grade for national accounts. The rating puts China on par with India and below Vietnam. Fixed asset investment data showed negative growth in 2025 for only the second time in decades. Property investment has fallen consistently since 2022. But official GDP investment data shows no signs of declining. The National Bureau of Statistics stopped publishing sectoral breakdowns of fixed asset investment in 2018. It discontinued a price series in 2021 and a land sales series in 2023. Beijing has restricted researcher access rather than addressing longstanding questions about data quality. China says it disagrees with the IMF's C rating. The government argued its production-side GDP approach is appropriate. Why does it matter? China is too large and too interconnected with the global economy for unreliable data to be a purely domestic issue. The lack of transparency creates problems for everyone trying to make decisions based on understanding China's economic trajectory. As Eswar Prasad, a professor at Cornell University and former IMF official, told FT: China is one of the two biggest economies in the world. "It would be nice to know what is really going on."

Boston Dynamics' Spot robot is now deployed by more than 60 bomb squads and SWAT teams across the US and Canada. The 75-pound four-legged machine starts at around $100,000 and has been used in armed standoffs, hostage rescues and hazardous materials incidents since its commercial debut five years ago. The Massachusetts State Police operates two Spot units purchased in 2020 and 2022. Each cost about $250,000 including add-ons funded through state grants. Last year one of the robots helped corner a suspect who had taken his mother hostage at knifepoint in Hyannis. Houston operates three units and Las Vegas has one. ICE recently spent around $78,000 on a similar robot from Canadian manufacturer Icor Technology that can also deploy smoke bombs. Civil liberties groups have raised concerns about normalizing militarized policing. The NYPD suspended its limited Spot program in 2021 after public backlash over cost and surveillance concerns before later reinstating it and purchasing two units. The Electronic Frontier Foundation says there should be state and federal laws providing guidance on appropriate use of such technology. About 2,000 Spot units now operate globally.

An anonymous reader shares a report: Federal health officials have linked two massive US measles outbreaks, confirming that the country is about two months away from losing its measles elimination status, according to a report by The New York Times. The Times obtained a recording of a call during which officials from the Centers for Disease Control and Prevention confirmed to state health departments that the ongoing measles outbreak at the border of Arizona and Utah is a continuation of the explosive outbreak in West Texas that began in mid- to late-January. That is, the two massive outbreaks are being caused by the same subtype of measles virus. This is a significant link that hasn't previously been reported despite persistent questions from journalists and concerns from health experts, particularly in light of Canada losing its elimination status last week. The loss of an elimination status means that measles will once again be considered endemic to the US, an embarrassing public health backslide for a vaccine-preventable disease.

Tsinghua University collected 4,986 AI and machine learning patents between 2005 and the end of 2024. The Beijing institution has received more than 900 patents last year alone. The total exceeds the combined patent count from MIT, Stanford, Princeton and Harvard during the same period. China now accounts for more than half of all active patent families globally in AI and machine learning fields, according to data analytics service LexisNexis. The university also has more AI research papers among the 100 most cited than any other school at last count. The US still holds the most influential AI patents and the top performing models. Harvard and MIT consistently rank ahead of Tsinghua in patent influence. American institutions produced 40 notable AI models in 2024 compared to 15 from Chinese organizations, according to Stanford's AI Index Report. China's share of the world's elite AI researchers -- the top 2% -- rose from 10% in 2019 to 26% in 2022. The US share fell from 35% to 28% during the same period, according to the Information Technology & Innovation Foundation.
