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 quotes a report from Ars Technica: On Thursday, Taiwan Semiconductor Manufacturing Company (TSMC) reported record fourth-quarter earnings and said it expects AI chip demand to continue for years. During an earnings call, CEO C.C. Wei told investors that while he cannot predict the semiconductor industry's long-term trajectory, he remains bullish on AI. "All in all, I believe in my point of view, the AI is real -- not only real, it's starting to grow into our daily life. And we believe that is kind of -- we call it AI megatrend, we certainly would believe that," Wei said during the call. "So another question is 'can the semiconductor industry be good for three, four, five years in a row?' I'll tell you the truth, I don't know. But I look at the AI, it looks like it's going to be like an endless -- I mean, that for many years to come." TSMC posted net income of NT$505.7 billion (about $16 billion) for the quarter, up 35 percent year over year and above analyst expectations. Revenue hit $33.7 billion, a 25.5 percent increase from the same period last year. The company expects nearly 30 percent revenue growth in 2026 and plans to spend between $52 billion and $56 billion on capital expenditures this year, up from $40.9 billion in 2025.

An anonymous reader shares a report: The prospect of Britain realigning its financial rules with the European Union has passed, and the country should avoid linking its regulations to any single jurisdiction, the ambassador for London's financial services sector told Reuters. Nearly a decade after Brexit, newly appointed Lady Mayor of London Susan Langley said that while maintaining dialogue with the EU remained important -- particularly on defence -- Britain should work with all nations that share its values and respect the rule of law. "We've still got huge alignment with Europe, cash flows between us are huge... Would we ever go back in terms of regulation? I think we've moved away from that," she said.

A new study from Cornell and University of Toronto researchers has found that polyester microfibers shed from synthetic clothing during laundry can interfere with cherry tomato plant development [non-paywalled source] when these particles accumulate in agricultural soil. Plants grown in contaminated soil were 11% less likely to emerge, grew smaller and took several days longer to flower and ripen. Household laundry is a leading source of this contamination. Treated sewage sludge retains roughly 90% of microfibers from washers, and farmers in some countries apply this material to up to 75% of cropland as fertilizer. Some scientists have questioned the methodology. Willie Peijnenburg, a professor of environmental toxicology at Leiden University, told WaPo the microfiber concentration used was much higher than field observations. His research suggests plants primarily absorb microplastics through airborne particles entering leaf stomata rather than through soil.

A researchers' propensity for risky projects is passed down to their doctoral students -- and stays with trainees after they leave the laboratory, according to an analysis of thousands of current and former PhD students and their mentors. From a report: Science involves taking risks, and some of the most impactful discoveries require taking big bets. However, scientists and policymakers have raised concerns that the current academic system's emphasis on short-term outcomes encourages researchers to play it safe. Studies have shown, for example, that risky research is less likely to be funded. Anders Brostrom, an economist studying science policy at the University of Gothenburg in Sweden, and his colleagues decided to examine the role of doctoral education in shaping risk-related behaviour -- an area that Brostrom says has been largely overlooked. "We often focus on thinking about how we can change the funding systems to make it more likely for people to take risks, but that's not the only lever we have," says Chiara Franzoni, an economist at the Polytechnic University of Milan in Italy. This study is "refreshing" because "we've discussed policy interventions a lot, but we haven't discussed training," she adds. [...] The team found that students' risk-taking dispositions matched those of their supervisors. This link was stronger when students and their supervisors communicated frequently, and weaker when students were also mentored by scientists outside their lab.

An anonymous reader shares a report: A hit song has been excluded from Sweden's official chart after it emerged the "artist" behind it was an AI creation. I Know, You're Not Mine -- or Jag Vet, Du Ar Inte Min in Swedish -- by a singer called Jacub has been a streaming success in Sweden, topping the Spotify rankings. However, the Swedish music trade body has excluded the song from the official chart after learning it was AI-generated. "Jacub's track has been excluded from Sweden's official chart, Sverigetopplistan, which is compiled by IFPI Sweden. While the song appears on Spotify's own charts, it does not qualify for inclusion on the official chart under the current rules," said an IFPI Sweden spokesperson. Ludvig Werber, IFPI Sweden's chief executive, said: "Our rule is that if it is a song that is mainly AI-generated, it does not have the right to be on the top list."

OpenAI said Friday that it will begin testing ads on ChatGPT in the coming weeks, as the $500 billion startup seeks new revenue streams to fund its continued expansion and compete against rivals Google and Anthropic. The company had previously resisted embedding ads into its chatbot, citing concerns that doing so could undermine the trustworthiness and objectivity of responses. The ads will appear at the bottom of ChatGPT answers on the free tier and the $8-per-month ChatGPT Go subscription in the U.S., showing only when relevant to the user's query. Pro, Business, and Enterprise subscriptions will remain ad-free. OpenAI expects to generate "low billions" of dollars from advertising in 2026, FT reported, and more in subsequent years. The revenue is intended to help fund roughly $1.4 trillion in computing commitments over the next decade. The company said it will not show ads to users under 18 or near sensitive topics like health, mental health, or politics.

Seattle was late to the light rail party -- the city rejected transit ballot measures in 1968 and 1971, missing out on federal funding that built Atlanta's MARTA, and didn't approve a plan including rail until 1996 -- but the Pacific Northwest city is now in the middle of a multibillion-dollar building boom that has produced the highest post-pandemic ridership recovery of any US light rail system. The Link system opened its first line in 2009, funded largely by voter-approved tax measures from 2008 and 2016. The north-south 1 Line now stretches 41 miles after a $3 billion extension to Lynnwood opened in June 2025 and a $2.5 billion leg to Federal Way debuted in December. Ridership is up 24% since 2019, and 3.4 million people rode Link trains in October 2025. Test trains have been running since September across the I-90 floating bridge over Lake Washington -- what Sound Transit claims is the world's first light rail on a floating structure -- preparing for a May 31 opening. The Crosslake Connection is part of the 2 Line, a 14-mile, $3.7 billion extension voters approved in 2008 that was originally slated to open in 2020. The expansion hasn't come without problems. Sound Transit faces a roughly $30 billion budget shortfall, and a planned Ballard extension has ballooned to $22 billion, double original estimates.

Salesforce CEO Marc Benioff said this week that his company's software engineering headcount has remained "mostly flat" over the past year as internal AI tools have delivered substantial productivity gains. Speaking on TBPN, Benioff said he has about 15,000 engineers who are "more productive than ever." The company has redirected its hiring efforts toward sales and customer engagement roles, hiring 20% more account executives this year as it pushes its Agentforce agentic AI service. Human salespeople remain essential for explaining the "intricacies and nuances" of agentic AI to skeptical enterprise customers, he argued. Other parts of the business have seen deeper cuts. In a separate appearance on The Logan Bartlett Show, Benioff said that Salesforce had reduced its customer support workforce by roughly 50%.

AI still can't produce code as well as most junior programmers he's worked with, David Heinemeier Hansson, the creator of Ruby on Rails and co-founder of 37 Signals, said on a recent podcast [video link], which is why he continues to write most of his code by hand. Hansson compared AI's current coding capabilities to "a flickering light bulb" -- total darkness punctuated by moments of clarity before going pitch black again. At his company, humans wrote 95% of the code for Fizzy, 37 Signals' Kanban-inspired organization product, he said. The team experimented with AI-powered features, but those ended up on the cutting room floor. "I'm not feeling that we're falling behind at 37 Signals in terms of our ability to produce, in terms of our ability to launch things or improve the products," Hansson said. Hansson said he remains skeptical of claims that businesses can fire half their programmers and still move faster. Despite his measured skepticism, Hansson said he marvels at the scale of bets the U.S. economy is placing on AI reaching AGI. "The entire American economy right now is one big bet that that's going to happen," he 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.

Tom's Hardware: Extensive research into the pricing of some of the best hard drives on the market for large capacity, economical storage indicates that prices are beginning to increase sharply, with some of the most popular models on the market seeing increases upwards of 60%. According to research from ComputerBase, pricing analysis on 12 of the most popular mainstream drives on the market indicates an average price increase of 46% over the last 4 months. While the research and price checks on these drives track movement based on European prices (ComputerBase is a German outlet), Tom's Hardware checks on similar or identical SKUs in the U.S. indicate that the trends are indeed replicated, or perhaps worse, on the other side of the pond. CB reports that various drives like Seagate's IronWolf NAS line, Toshiba's Cloud Scale Capacity Drives, Western Digital's WD Red, and Seagate's BarraCuda lines are all showing price increases of between 23% and 66%. As noted, the average price increases clock in at 46% since September 2025.

theodp writes: Code.org, the nonprofit backed by AI giants Microsoft, Google and Amazon and whose Hour of AI and free AI curriculum aim to make world's K-12 schoolchildren AI literate, points job seekers to its AI Use Policy in Hiring, which promises dire consequences for those who use AI during interviews or take home assignments without its OK. Explaining "What's Not Okay," Code.org writes: "While we support thoughtful use of AI, certain uses undermine fairness and honesty in the hiring process. We ask that candidates do not [...] use AI during interviews and take-home assignments without explicit consent from the interview team. Such use goes against our values of integrity and transparency and will result in disqualification from the hiring process." Interestingly, Code.org CEO Partovi last year faced some blowback from educators over his LinkedIn post that painted schools that police AI use by students as dinosaurs. Partovi wrote, "Schools of the past define AI use as 'cheating.' Schools of the future define AI skills as the new literacy. Every desk-job employer is looking to hire workers who are adept at AI. Employers want the students who are best at this new form of 'cheating.'"

An anonymous reader quotes a report from the Wall Street Journal: Amazon is turning to an Arizona mine that last year became the first new source of U.S. copper in more than a decade, to meet its data centers' ravenous appetite for the industrial metal. The mine was restarted as a proving ground for Rio Tinto's new method of unlocking low-grade copper deposits. Rio signed a two-year supply pact with Amazon Web Services, a vote of confidence for its Nuton venture, which uses bacteria and acid to extract copper from ore that was previously uneconomical to process. The move by Amazon is the latest example of a technology company rushing to secure the power and critical materials necessary to build and operate artificial-intelligence data centers. The Nuton copper will satisfy only a sliver of Amazon's needs. The biggest data centers each require tens of thousands of metric tons of copper for all the wires, busbars, circuit boards, transformers and other electrical components housed there. The 14,000 metric tons of copper cathode that Rio expects the Arizona Nuton project to yield over four years wouldn't be enough for one of those facilities. Rio deployed its bioleaching process in the recent restart of a mine east of Tucson and has partnerships to take the technology to several others in the Americas. The idea is to uncork the low-grade ore left behind at old mines and is key to Rio's plans to boost output when new discoveries are harder than ever to bring online and copper demand is surging. [...] "We work at the commodity level to find lower carbon solutions to drive our business growth," said Chris Roe, Amazon's director of worldwide carbon. "That means steel, and that means concrete, and it absolutely means copper with regard to our data centers." Roe said the copper will be routed to companies that produce components for Amazon's data centers. As part of the deal, Amazon is supplying Rio with cloud-computing and data analytics to optimize Nuton's recovery rates and help the miner expand production.

After more than 13 years leading Lucasfilm, Kathleen Kennedy is stepping down. "When George Lucas asked me to take over Lucasfilm upon his retirement, I couldn't have imagined what lay ahead," said Kennedy. "It has been a true privilege to spend more than a decade working alongside the extraordinary talent at Lucasfilm." The Associated Press reports: The Walt Disney Co. announced Thursday that it will now turn to Dave Filoni to steer "Star Wars," as president and chief creative officer, into its sixth decade and beyond. Filoni, who served as the chief commercial officer of Lucasfilm, will inherit the mantle of one of the movies marquee franchises, alongside Lynwen Brennan, president and general manager of Lucasfilm's businesses, who will serve as co-president. Kennedy, Lucas' handpicked successor, had presided over the ever-expanding science-fiction world of "Star Wars" since Disney acquired it in 2012. In announcing Thursday's news, Bob Iger, chief executive officer of the Walt Disney Co. called her "a visionary filmmaker." Kennedy oversaw a highly lucrative but often contentious period in "Star Wars" history that yielded a blockbuster trilogy and acclaimed streaming spinoffs such as "The Mandalorian" and "Andor," yet found increasing frustration from longtime fans. Under Kennedy's stewardship, Lucasfilm amassed more than $5.6 billion in box office and helped establish Disney+ as a streaming destination -- achievements that easily validated the $4.05 billion Disney plunked down for the company. But Kennedy also struggled to deliver the big-screen magic that Lucas captured in the original trilogy from the late 1970s and early 1980s, and her relationship with "Star Wars" loyalists became a saga of its own.

In a reversal from previous years, U.S. carbon emissions rose 2.4% in 2025 compared with the year before. NBC News reports: The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of data centers and cryptocurrency mining and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by President Donald Trump's administration were not significant factors in the increase because they were only put in place this year, the study authors said. Heat-trapping gases from the burning of coal, oil and natural gas are the major cause of worsening global warming, scientists say. American emissions of carbon dioxide and methane had dropped 20% from 2005 to 2024, with a few one- or two-year increases in the overall downward trend. Traditionally, carbon pollution has risen alongside economic growth, but efforts to boost cleaner energy in recent years decoupled the two, so emissions would drop as gross domestic product rose. But that changed last year with pollution actually growing faster than economic activity, said study co-author Ben King, a director in Rhodium's energy group. He estimated the U.S. put 5.9 billion tons (5.35 billion metric tons) of carbon dioxide equivalent in the air in 2025, which is 139 million tons (126 million metric tons) more than in 2024. The cold 2025 winter meant more heating of buildings, which often comes from natural gas and fuel oil that are big greenhouse gas emitters, King said. A significant and noticeable jump in electricity demand from data centers and cryptocurrency mining meant more power plants producing energy. That included plants using coal, which creates more carbon pollution than other fuel sources. A rise in natural gas prices helped create an 13% increase in coal power, which had shrunk by nearly two-thirds since its peak in 2007, King said.

An anonymous reader quotes a report from the Guardian: Screen time spent gaming or on social media does not cause mental health problems in teenagers, according to a large-scale study. [...] Researchers at the University of Manchester followed 25,000 11- to 14-year-olds over three school years, tracking their self-reported social media habits, gaming frequency and emotional difficulties to find out whether technology use genuinely predicted later mental health difficulties. Participants were asked how much time on a normal weekday in term time they spent on TikTok, Instagram, Snapchat and other social media, or gaming. They were also asked questions about their feelings, mood and wider mental health. The study found no evidence for boys or girls that heavier social media use or more frequent gaming increased teenagers' symptoms of anxiety or depression over the following year. Increases in girls' and boys' social media use from year 8 to year 9 and from year 9 to year 10 had zero detrimental impact on their mental health the following year, the authors found. More time spent gaming also had a zero negative effect on pupils' mental health. "We know families are worried, but our results do not support the idea that simply spending time on social media or gaming leads to mental health problems -- the story is far more complex than that," said the lead author Dr Qiqi Cheng. The research, published in the Journal of Public Health, also examined whether how pupils use social media makes a difference, with participants asked how much time spent chatting with others, posting stories, pictures and videos, browsing feeds, profiles or scrolling through photos and stories. The scientists found that actively chatting on social media or passive scrolling feeds did not appear to drive mental health difficulties. The authors stressed that the findings did not mean online experiences were harmless. Hurtful messages, online pressures and extreme content could have detrimental effects on wellbeing, but focusing on screen time alone was not helpful, they said.

Amazon is expanding the Fallout universe with Fallout Shelter, a ten-episode reality competition show where contestants face survival-style challenges and moral dilemmas for a cash prize. Engadget reports: Prime Video has greenlit a unscripted reality show titled Fallout Shelter. It will be a ten-episode run with Studio Lambert, the team behind reality projects including Squid Game: The Challenge and The Traitors, as its primary producer. Bethesda Game Studios' head honcho Todd Howard is attached as an executive producer. Amazon's description of Fallout Shelter is: "Across a series of escalating challenges, strategic dilemmas and moral crossroads, contestants must prove their ingenuity, teamwork and resilience as they compete for safety, power and ultimately a huge cash prize." [...] The name echos the free-to-play mobile game Bethesda released in 2015. Fallout Shelter lets people build and improve their out Vault-Tec residence, managing the resources for a growing cadre of underground survivors. It seems pretty likely that there will be some type of tie-in between the game and the show, but any details about that might pop up closer to when the program is ready to air. It's currently casting, and no release timeline has been shared.

New York Governor Kathy Hochul is proposing first-of-its-kind legislation that would require 3D printers sold in the state to include built-in software designed to block the printing of gun parts used to make "ghost guns." The plan would also add criminal penalties for making 3D-printed firearms and hold printer owners or manufacturers liable if safety controls aren't in place. 3D Printing Industry reports: "From the iron pipeline to the plastic pipeline, these proposals will keep illegal ghost guns off of New York streets, and enhance measures to track and block the production of dangerous and illegal firearms in our state," Hochul said. In addition to mandating printer-level safeguards and restricting access to CAD files, the proposed legislation would require law enforcement agencies to report any recovered 3D printed firearms to a statewide database. The measure also includes a provision requiring commercial gun manufacturers to redesign pistols so they cannot be easily converted for automatic fire. "These illegal firearms are being manufactured in homes and used in crimes right now, which is why I have been working with my colleagues in Albany and the private sector over the past several years to stop their proliferation. Passing these measures will reduce crime and strengthen public safety for all New Yorkers," said Manhattan District Attorney Alvin Bragg.
