  • Canada Plans 'Nuclear Renaissance' With Up To 10 Reactors Built By 2040
    by BeauHD on 23/06/2026 at 11:00 am

    Canada has unveiled a national strategy to build up to 10 new nuclear reactors over the next 15 years as it seeks to double electricity-grid capacity by 2050. Energy Minister Tim Hodgson called it a plan for a "new civilian nuclear renaissance." "If our goal is to double our grid and build a low-carbon economy in less than 25 years, there is no credible plan to do that without nuclear energy and the clean, reliable baseload power it provides," Hodgson said. "There is no credible plan for Canada to become an energy superpower if we choose not to build upon one of the strongest energy advantages we have." CBC News reports: The strategy calls for construction to start on two new large-scale reactors by 2035, for five more to be planned or under development by 2040 and for at least one reactor to be under construction outside Ontario by 2035. It also calls for a Canadian-made microreactor to be finalized by 2035 and deployed to a remote community by the late 2030s. [...] Right now, Canada has four nuclear power plants -- three in Ontario and one in New Brunswick -- which generate about 15 per cent of Canada's electricity. A new proposed facility at the existing nuclear plant in Darlington, Ont., would see the first small modular reactor in the G7, capable of producing up to 300 megawatts per unit. Saskatchewan is also looking at the potential to bring small nuclear reactors online by the mid 2030s. The energy deal between Ottawa and Alberta also committed to collaborating on developing a strategy to build a nuclear power plant. Officials from Natural Resources Canada told reporters in a background briefing that construction of the reactors outlined in the new national strategy could cost more than $100 billion. The strategy does not say how Canada would pay for them, though an official pointed to the Canadian Infrastructure Bank and the Canada Growth Fund as possible funding sources. Hodgson said the strategy would double the 90,000 jobs in Canada's nuclear sector "over the coming decades." The plan also looks to expand sales of Candu reactors to new export markets. It says the government wants to break into at least four new international markets by 2040 and "engage six to 10 new nuclear entrant markets over a 15-year horizon, cementing Canada as their partner of choice." Thirty Candu reactors currently operate around the world, including in South Korea, China, India, Argentina, Pakistan and Romania, and there are plans to build two more. [...] "Reactor exports are not transactional. They establish multi-decade partnerships, creating durable geopolitical and commercial relationships that advance Canada's broader foreign policy interests," the strategy says. "As Canada works to diversify its trading relationships and strengthen ties with middle powers, Candu can be a central instrument of that strategy." Read more of this story at Slashdot.

  • NASA's Nancy Grace Roman Space Telescope Arrives In Florida
    by BeauHD on 23/06/2026 at 7:00 am

    NASA's Nancy Grace Roman Space Telescope has arrived at Kennedy Space Center ahead of a Falcon Heavy launch targeted for no earlier than August 30. The observatory will survey the sky about 1,000 times faster than Hubble with a field of view at least 100 times wider, helping scientists study dark matter, dark energy, and exoplanets. Spaceflight Now reports: NASA's next great observatory, the Nancy Grace Roman Space Telescope, arrived at the Kennedy Space Center aboard the agency's massive Pegasus barge late Sunday morning. The spacecraft was nestled inside its protective case, which NASA nicknamed the "Chariot" in keeping with the "Roman" theme. That said, telescope is named not for the ancient empire, but instead for NASA's first Chief of Astronomy, Nancy Grace Roman. "She was a key person in our exploration of space. She understood that in order to better understand the universe, you have to go in space," said Lucas Paganini, the program executive for Roman. "That's why she's called the 'Mother of Hubble' because she made Hubble possible." [...] Roman is designed to operate near a fixed point in space called Lagrange Point 2, about 1.5 million km away from the Earth on the side opposite the Sun. It's designed to operate there for a minimum of five years, but Paganini said with the propellant onboard, it will likely last for 10 years or more. The telescope is+ equipped with a 300 megapixel camera called the Wide Field Instrument, which features 18 detectors. It was developed by BAE Systems (formerly Ball Aerospace). "It's going to allow us to observe at least 100 times wider field of view than what we can do with Hubble. Same resolution, but a wider area, 1000 times faster," Paganini said. "So what takes Roman a year to observe, it would take Hubble thousands of years. So it's definitely much more efficient." The observatory also features a chronograph instrument, developed by the Jet Propulsion Laboratory, which will allow Roman to observe the faint light of exoplanets near their stars. Paganini said Roman will also help scientists better understand dark matter and dark energy, the combination of which he calls the "dark universe." "100 years ago, we discovered that the universe was expanding. 25 years ago, we discovered that it was expanding at an accelerated pace and that's what led to a Nobel Prize," Paganini said. "What we don't quite know yet is if that acceleration is changing in ways. We don't know if it's actually dark energy, what is producing it, or is it simply that we don't understand gravity at all. "So eventually, we'll see if the laws of physics that we use these days are the right ones for what we are observing. But at the end is, we're trying to understand a very human question, which is where do we come from and where are wea heading in this universe that is our neighborhood?"

  • GM Installs Robots At Flagship EV Factory After Laying Off 1,300 Workers
    by BeauHD on 23/06/2026 at 3:30 am

    An anonymous reader quotes a report from Ars Technica: Dozens of new robot arms have been installed at General Motors' flagship electric vehicle factory in Detroit -- even as 1,300 workers remain out of work following what was supposed to be a temporary layoff. The latest automation push has spurred union pushback over a potentially existential issue for automakers and their workers. General Motors installed approximately 50 robot arms at GM's Factory Zero plant in Detroit, Michigan, according to reporting by Crain's Detroit Business. Made by the Japanese robotics company FANUC, the robots are designed to help attach various components to vehicles during the assembly line process. But leaders at United Auto Workers (UAW), the primary US union for autoworkers, reacted with anger to the new robotic presence, given how GM has not yet called back any of the workers affected by supposedly temporary layoffs in March. More than 1,000 union members are still "laid off indefinitely," James Cotton, president of UAW Local 22, told The Detroit News. He said that the company could bring some of those members back to work instead of installing the 50 robots. The temporary layoffs were preceded by permanent layoffs involving another 1,200 workers at GM's Factory Zero in October 2025. Many automakers, including Stellantis NV and Ford Motor Company, have deployed assembly-line robots, such as Fanuc robot arms, as they push to automate more of their US operations. Hyundai Motor Company plans to deploy Atlas humanoid robots made by Boston Dynamics -- which Hyundai acquired in 2020 -- to start working in the automaker's flagship EV facility in Georgia by 2028. "Technological development has the capability of making work safer for the working class and enabling workers to have a shorter work week without losing pay," said Andrew Bergman, a Local 22 member and union organizer who was among those laid off by GM. "But in the bosses' and billionaires' hands it's used to pad profits and lay off workers." Read more of this story at Slashdot.

  • Microsoft Accidentally Breaks Replying To an Email On Outlook
    by BeauHD on 22/06/2026 at 11:00 pm

    Microsoft has accidentally introduced a bug in Outlook for Mac that omits the original message from email replies, making it difficult for recipients to follow conversation history. Until Microsoft releases a fix, its suggested workaround is to roll back from version 16.110 and disable automatic updates, which is "great for users in full control of their devices -- not so good for anyone with a managed device," notes The Register. "Administrators with fleets of Macs running Outlook should brace for helpdesk tickets." From the report: In some instances, having a user copy and paste the salient bits of the email they are responding to might not be such a bad thing. We've all had emails that required epic amounts of scrolling to find what started the conversation, so forcing users to think about what they actually need to include is no bad thing. However, disrupting user workflows without warning -- well, that is undoubtedly a bad thing. This is, after all, one of the most basic things an email client needs to do, so shipping a product with a bug that breaks this functionality says more about Microsoft's approach to quality than anything else.

  • Following User Outcry, AMD Reinstates Memory Encryption In Consumer CPUs
    by BeauHD on 22/06/2026 at 10:00 pm

    Last week, AMD was found to have stripped memory encryption from its consumer CPUs without any warning or notice. Now, following a wave of backlash on social media, the chipmaker has now reinstated the protection, though it still hasn't explained why the safeguard was disabled in the first place. Ars Technica reports: Following the revelation, social media was deluged by comments from AMD consumers decrying the move. They noted that AMD's quiet removal of TSME after supporting it for so long seemed underhanded. The move came solely as a result of firmware changes made in a recent update. With no physical changes required to silicon, continued support was largely, if not purely, a matter of will rather than a necessity required by changes to hardware. The critics called on AMD to reverse the move. Over the weekend, AMD said it planned to do just that in a firmware update scheduled for release next month. More often than not, the chipmaker refers to TSME as Memory Guard. "Regarding certain non-PRO Ryzen 9000-series desktop processors, a BIOS option to enable Memory Guard was previously available but was removed in a recent update," AMD said in an email. "Based on valuable community feedback, we will reinstate this option in an upcoming BIOS release in July." The company has yet to explain why it removed the protection. Critics speculate that AMD dropped it in an attempt to steer customers toward more costly CPUs. It's possible, though, that there were less nefarious reasons, such as the difficulty of continued support as chip designs changed. Another possibility is that AMD made the move for performance reasons. Encrypting and decrypting data in memory creates latency. Slowdowns are the enemy of gamers, one of the more popular customer segments using the 9000-line of Ryzen processors. Since many gamers already voluntarily disabled TSME and had little need for it in the first place, AMD may not have considered the change of much consequence. Read more of this story at Slashdot.

  • Valve Will Finally Let You Build Your Own Steam Machine With SteamOS For Desktop
    by BeauHD on 22/06/2026 at 9:00 pm

    With the price of the new Steam Machine starting at $1,049, you might want to consider making your own Steam Machine instead. An anonymous reader quotes a report from The Verge: Valve says that "starting with the SteamOS 3.8 release, you can put together your own Steam Machine using whatever PC parts you want." SteamOS 3.8.10 launched last week with a slew of updates, including "improved compatibility with recent Intel and AMD platforms." Alongside that improved compatibility, Valve is giving gamers the green light to install SteamOS on their own desktops. In an interview with The Verge, Valve's Pierre-Loup Griffais said Valve has been "rolling out improvements to [SteamOS] so it's more compatible with desktop hardware," including eventual support for Nvidia graphics. Griffais says Valve has "a growing team" working on Nvidia driver support for SteamOS, adding, "We're collaborating with Nvidia very closely." While he mentioned that Nvidia support might not come this year, Griffais emphasized that "it's certainly something that we're working on in the background." It's technically been possible to run SteamOS on your own hardware for a while now, but compatibility has been mostly limited to AMD systems. So far installing it has also required using a Steam Deck recovery image, a process that, speaking from experience, is much less straightforward than the installation process for most other Linux distributions. Trying to run SteamOS on Intel or Nvidia hardware has not been easy so far. According to Griffais, Valve is working to change that, which could mean that down the line, you'll be able to run SteamOS on just about any gaming PC hardware you want, including Nvidia. For the more immediate future, Griffais says SteamOS in its current state should offer a "good experience" on console-like PC setups: "If you have something that is similar to the use case of a Steam Machine, where you have a PC that's gonna be plugged into a TV, and has a single hard drive that you're not going to try and dual boot [] you can put SteamOS on there, and you'll have an experience that is very similar to a Steam Deck docked or a Steam Machine, with some caveats, of course," like a lack of HDMI-CEC support. But "the core bits of the experience are there. The SteamOS graphics driver, the shader precompilation [...] you can get at all of that with the SteamOS." Griffais says SteamOS does not yet offer an easy way to dual-boot alongside Windows or another operating system, but envisions "a time where it's a better experience to install on your desktop and have it coexist with a different operating system."
