  • The Fastest Human Spaceflight Mission In History Crawls Closer To Liftoff
    by BeauHD on 20/01/2026 at 3:30 am

    An anonymous reader quotes a report from Ars Technica: Preparations for the first human spaceflight to the Moon in more than 50 years took a big step forward this weekend with the rollout of the Artemis II rocket to its launch pad. The rocket reached a top speed of just 1 mph on the four-mile, 12-hour journey from the Vehicle Assembly Building to Launch Complex 39B at NASA's Kennedy Space Center in Florida. At the end of its nearly 10-day tour through cislunar space, the Orion capsule on top of the rocket will exceed 25,000 mph as it plunges into the atmosphere to bring its four-person crew back to Earth. "This is the start of a very long journey," said NASA Administrator Jared Isaacman. "We ended our last human exploration of the moon on Apollo 17." [...] "We really are ready to go," said Wiseman, the Artemis II commander, during Saturday's rollout to the launch pad. "We were in a sim [in Houston] for about 10 hours yesterday doing our final capstone entry and landing sim. We got in T-38s last night and we flew to the Cape to be here for this momentous occasion." The rollout began around sunrise Saturday, with NASA's Space Launch System rocket and Orion capsule riding a mobile launch platform and a diesel-powered crawler transporter along a throughway paved with crushed Alabama river rock. Employees, VIPs, and guests gathered along the crawlerway to watch the 11 million-pound stack inch toward the launch pad. The rollout concluded about an hour after sunset, when the crawler transporter's jacking system lowered the mobile launch platform onto pedestals at Pad 39B. The rollout keeps the Artemis II mission on track for liftoff as soon as next month, when NASA has a handful of launch opportunities on February 6, 7, 8, 10, and 11. The big milestone leading up to launch day will be a practice countdown or Wet Dress Rehearsal (WDR), currently slated for around February 2, when NASA's launch team will pump more than 750,000 gallons of super-cold liquid hydrogen and liquid oxygen into the rocket. NASA had trouble keeping the cryogenic fluids at the proper temperature, then encountered hydrogen leaks when the launch team first tried to fill the rocket for the unpiloted Artemis I mission in 2022. Engineers implemented the same fixes on Artemis II that they used to finally get over the hump with propellant loading on Artemis I. [...] If the launch does not happen in February, NASA has a slate of backup launch dates in early March. Read more of this story at Slashdot.

  • The World's Longest-Running Lab Experiment Is Almost 100 Years Old
    by BeauHD on 20/01/2026 at 2:30 am

    alternative_right shares a report from ScienceAlert: It all started in 1927, when physicist Thomas Parnell at the University of Queensland in Australia filled a closed funnel with the world's thickest known fluid: pitch, a derivative of tar that was once used to seal ships against the seas. Three years later, in 1930, Parnell cut the funnel's stem, like a ribbon at an event, heralding the start of the Pitch Drop Experiment. From then on, the black substance began to flow. At least, that is, in a manner of speaking. At room temperature pitch might look solid, but it is actually a fluid 100 billion times more viscous than water. It took eight years for the first droplet to finally hit the beaker below. Then, they dripped at a cadence of once every eight years or so, slowing down only after air conditioning was installed in the building in the 1980s. Today, 96 years after the funnel was cut, only nine drops in total have seeped out. The last was in 2014. Scientists expect another will fall sometime in the 2020s, but they are still waiting. No one has ever actually seen a droplet fall directly, despite all the watchful eyes. The experiment is now live-streamed, but various glitches in the past meant that each fateful moment has slipped us by. Read more of this story at Slashdot.

  • Germany's EV Subsidies Will Include Chinese Brands
    by BeauHD on 20/01/2026 at 1:50 am

    Germany is reinstating EV subsidies after a sharp sales drop, rolling out a 3 billion-euro program offering 1,500-6,000 euros per buyer starting in May and running through 2029. Unlike some neighboring countries, the incentives are open to all manufacturers with a focus on low- and middle-income households. From a report: "I cannot see any evidence of this postulated major influx of Chinese car manufacturers in Germany, either in the figures or on the roads -- and that is why we are facing up to the competition and not imposing any restrictions," German Environment Minister Carsten Schneider said at a Monday press conference. The decision is a major boon for affordable Chinese automakers like BYD that are steadily gaining ground in the European market, [Bloomberg noted]. Germany's green-light for Chinese EVs stands in stark contrast to other nations' approaches. In the UK, subsidies introduced last year effectively excluded Chinese battery-powered vehicles, while France's so-called social leasing scheme includes similar restrictions. [...] Germany maintains strong diplomatic ties with China. German automakers are among the most significant players in China's automotive industry. Over the past years, China's policies -- including purchase subsidies and purchase tax reductions -- have not excluded models or automakers from specific countries. Whether German automakers like Volkswagen or American automakers like Tesla, all enjoy national-level purchase incentive policies in China on par with domestic automakers.

  • A Second US Sphere Could Come To Maryland
    by BeauHD on 20/01/2026 at 1:10 am

    Sphere Entertainment plans to build a second U.S. Sphere near Washington, D.C., with a smaller 6,000-seat "mini-Sphere" proposed for National Harbor in Maryland. The venue would retain the signature LED exterior and immersive 4D tech of the Las Vegas Sphere, just at a more compact scale. The Verge reports: The second US sphere would be built in an area known as National Harbor in Prince George's County, Maryland. Located along the Potomac River, National Harbor currently features a convention center, multiple hotels, restaurants, and shops. While Abu Dhabi plans to build a sphere as large as the one in Las Vegas, the National Harbor venue would be one of the first mini-Sphere venues announced last March. Its capacity would be limited to 6,000 seats instead of over 17,000. But the smaller Sphere would still be hard to miss with an exterior LED exosphere for showcasing the "artistic and branded content" that helped make the original sphere a unique part of the Las Vegas skyline. The inside of the mini-Sphere will feature a high-resolution 16,000 by 16,000 pixel wrap-around screen, the company's immersive sound technology, haptic seating, and "4D environmental effects." For the AI-enhanced version of The Wizard of Oz currently playing in Las Vegas, audiences experience effects like wind, fog, smells, and apples falling from the ceiling.

  • Nvidia Contacted Anna's Archive To Secure Access To Millions of Pirated Books
    by BeauHD on 20/01/2026 at 12:30 am

    An anonymous reader quotes a report from TorrentFreak: NVIDIA executives allegedly authorized the use of millions of pirated books from Anna's Archive to fuel its AI training. In an expanded class-action lawsuit that cites internal NVIDIA documents, several book authors claim (PDF) that the trillion-dollar company directly reached out to Anna's Archive, seeking high-speed access to the shadow library data. [...] Last Friday, the authors filed an amended complaint that significantly expands the scope of the lawsuit. In addition to adding more books, authors, and AI models, it also includes broader "shadow library" claims and allegations. The authors, including Abdi Nazemian, now cite various internal Nvidia emails and documents, suggesting that the company willingly downloaded millions of copyrighted books. The new complaint alleges that "competitive pressures drove NVIDIA to piracy," which allegedly included collaborating with the controversial Anna's Archive library. According to the amended complaint, a member of Nvidia's data strategy team reached out to Anna's Archive to find out what the pirate library could offer the trillion-dollar company "Desperate for books, NVIDIA contacted Anna's Archive -- the largest and most brazen of the remaining shadow libraries -- about acquiring its millions of pirated materials and 'including Anna's Archive in pre-training data for our LLMs,'" the complaint notes. "Because Anna's Archive charged tens of thousands of dollars for 'high-speed access' to its pirated collections [] NVIDIA sought to find out what "high-speed access" to the data would look like." According to the complaint, Anna's Archive then warned Nvidia that its library was illegally acquired and maintained. Because the site previously wasted time on other AI companies, the pirate library asked NVIDIA executives if they had internal permission to move forward. This permission was allegedly granted within a week, after which Anna's Archive provided the chip giant with access to its pirated books. "Within a week of contacting Anna's Archive, and days after being warned by Anna's Archive of the illegal nature of their collections, NVIDIA management gave 'the green light' to proceed with the piracy. Anna's Archive offered NVIDIA millions of pirated copyrighted books." The complaint states that Anna's Archive promised to provide NVIDIA with access to roughly 500 terabytes of data. This included millions of books that are usually only accessible through Internet Archive's digital lending system, which itself has been targeted in court. The complaint does not explicitly mention whether NVIDIA ended up paying Anna's Archive for access to the data. Additionally, it's worth mentioning that NVIDIA also stands accused of using other pirated sources. In addition to the previously included Books3 database, the new complaint also alleges that the company downloaded books from LibGen, Sci-Hub, and Z-Library. In addition to downloading and using pirated books for its own AI training, the authors allege NVIDIA distributed scripts and tools that allowed its corporate customers to automatically download "The Pile", which contains the Books3 pirated dataset.

  • OpenAI CFO Says Annualized Revenue Crosses $20 Billion In 2025
    by BeauHD on 19/01/2026 at 11:50 pm

    According to CFO Sarah Friar, OpenAI's annualized revenue surpassed $20 billion in 2025, up from $6 billion a year earlier with growth closely tracking an expansion in computing capacity. Reuters reports: OpenAI's computing capacity rose to 1.9 gigawatts (GW) in 2025 from 0.6 GW in 2024, Friar said in the blog, adding that Microsoft-backed OpenAI's weekly and daily active users figures continue to produce all-time highs. OpenAI last week said it would start showing ads in ChatGPT to some U.S. users, ramping up efforts to generate revenue from the AI chatbot to fund the high costs of developing the technology. Separately, Axios reported on Monday that OpenAI's policy chief Chris Lehane said that the company is "on track" to unveil its first device in the second half of 2026. Friar said OpenAI's platform spans text, images, voice, code and APIs, and the next phase will focus on agents and workflow automation that run continuously, carry context over time, and take action across tools. For 2026, the company will prioritize "practical adoption," particularly in health, science and enterprise, she said. Friar said the company is keeping a "light" balance sheet by partnering rather than owning and structuring contracts with flexibility across providers and hardware types.
