The US Effort to Break China's Rare-Earth Monopoly
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.

Reddit Surges in Popularity to Overtake TikTok in the UK - Thanks to Google's Algorithm?
Reddit "has overtaken TikTok as Britain's fourth most-visited social media service," reports the Guardian:
The platform has undergone huge growth over the last two years, with an 88% increase in the proportion of UK internet users it reaches. Three in five Brits online now encounter the site, up from a third in 2023, according to Ofcom. Its popularity is rising fastest with younger internet users. It is now the sixth most visited organisation of any kind by UK users aged between 18 and 24, up from 10th a year earlier. More than three-quarters of that cohort now visit it....
The UK is a boom market for the platform, with the second largest user base behind the US, according to company records. A series of factors are behind its rise. However, a change in Google's search algorithms last year to prioritise helpful content from discussion forums appears to have been a significant driver. A recent deal with Google that allows the company to train its AI model on Reddit's content also appears to have provided a boost. Reddit is the most-cited source for Google AI overviews, which is likely to see more people directed to its forums. It has a similar deal with OpenAI, which owns the most popular AI chatbot, ChatGPT.
According to the article, Reddit "believes it is also benefiting from shifting internet habits, as younger users seek out human-generated reviews and opinions."

New Tesla Video Shows Tesla Semi Electric Truck Charging at 1.2 MW
An anonymous reader shared this report from Electrek:
Tesla has released a new video showing a Tesla Semi truck charging at a massive 1.2 megawatts (MW), finally giving us a clear look at the charging speeds that will enable long-haul electric trucking...>
Tesla claimed the Semi would be able to charge 70% of its range in 30 minutes. For a truck with a 500-mile range and an estimated battery pack of around 800-900 kWh, that requires an incredibly high power output, well beyond the 250 kW or even 350 kW we see on passenger EVs in North America. Today, the official Tesla Semi account on X released a video showing exactly that. In the video, Tesla engineers are seen monitoring a charging session where the power output climbs to a peak of 1.2 MW (1,206 kW).
This is consistent with the capabilities Tesla announced for its new V4 Cabinet architecture earlier this year. The V4 cabinets are designed to support 400V-1000V vehicle architectures and can deliver up to 500 kW for cars (like the Cybertruck) and up to 1.2 MW for the Semi. There is some information missing from the video. For example, we don't see the state-of-charge of the truck, so we don't at what battery percentage Tesla Semi can achieve and maintain this charge rate. Peak speed is one thing, but sustaining that power without overheating the pack or the cable is the real challenge. The liquid-cooled charging cable and the immersion-cooled connector (part of the Megawatt Charging System or a high-power proprietary Tesla solution, though Tesla has been leaning toward MCS compatibility) seem to be doing their job....
This comes just as Tesla is gearing up for volume production of the Semi at its new factory expansion near Gigafactory Nevada. The automaker is targeting a start of production in the first half of 2026 and a ramp up to volume production in the second half.

What Happened When Alaska's Court System Tried Answering Questions with an AI Chatbot?
An AI chatbot to answer probate questions from Alaska residents "was supposed to be a three-month project," said Aubrie Souza, a consultant with the National Center for State Courts told NBC News. "We are now at well over a year and three months, but that's all because of the due diligence that was required to get it right."
"With a project like this, we need to be 100% accurate, and that's really difficult with this technology," said Stacey Marz, the administrative director of the Alaska Court System and one of the Alaska Virtual Assistant (AVA) project's leaders... While many local government agencies are experimenting with AI tools for use cases ranging from helping residents apply for a driver's license to speeding up municipal employees' ability to process housing benefits, a recent Deloitte report found that less than 6% of local government practitioners were prioritizing AI as a tool to deliver services. The AVA experience demonstrates the barriers government agencies face in attempting to leverage AI for increased efficiency or better service, including concerns about reliability and trustworthiness in high-stakes contexts, along with questions about the role of human oversight given fast-changing AI systems. These limitations clash with today's rampant AI hype and could help explain larger discrepancies between booming AI investment and limited AI adoption.
The chatbot was developed with Tom Martin, a lawyer/law professor who designs legal AI tools, according to the article. But the project "had to contend with the serious issue of hallucinations, or instances in which AI systems confidently share false or exaggerated information."
"We had trouble with hallucinations, regardless of the model, where the chatbot was not supposed to actually use anything outside of its knowledge base," Souza told NBC News. "For example, when we asked it, 'Where do I get legal help?' it would tell you, 'There's a law school in Alaska, and so look at the alumni network.' But there is no law school in Alaska." Martin has worked extensively to ensure the chatbot only references the relevant areas of the Alaska Court System's probate documents rather than conducting wider web searches.
The article concludes that "what was meant to be a quick, AI-powered leap forward in increasing access to justice has spiraled into a protracted, yearlong journey plagued by false starts and false answers." But the chatbot is now finally scheduled to be launched in late January. "It was just so very labor-intensive to do this," Marz said, despite "all the buzz about generative AI, and everybody saying this is going to revolutionize self-help and democratize access to the courts.
"It's quite a big challenge to actually pull that off."

Google's $250M Deal with California to Fund Newsrooms May Be Stalled
Remember how California's government negotiated a 2024 deal where Google contributed millions to California's local newsrooms to offset advertisers moving to the search engine?
"A year after it was cemented — and billed as a model that could succeed where entire countries and continents had fallen short — the agreement is tangled in budget cuts, bureaucratic infighting and unresolved questions about who controls the money," reports Politico, "leaving journalists empty-handed and casting doubt on whether the lofty experiment will ever live up to its promise."
The program, initially framed as a nearly $250 million commitment over five years, has secured just $20 million in new money for journalists in its first year, with no guarantee the funding will continue. It's changed hands twice since the University of California, Berkeley withdrew its support [with school officials "worried they wouldn't have enough of a say in how the money was distributed"]. Suggestions that other big tech players like ChatGPT-maker OpenAI could front more resources haven't materialized. A $62.5 million "AI accelerator" tied to the deal hasn't been set up yet.
Not a single newsroom has seen a dollar of funding, and there's no definitive timeline spelling out when they will... [The article adds later that state officials "have yet to draft precise rules for how California will decide which newsrooms get cash..."] Conversations with at least 20 people involved in the deal's rollout reveal how California's budget shortfalls and intraparty spats among Democrats scrambled it... California's struggle to launch its program has dampened hopes of replicating its model in other states such as Oregon, Illinois and New York, where lawmakers have tried but failed to make Big Tech pay for news...
When [California governor] Newsom unveiled his final state budget plan in May 2025 after a $12 billion deficit suddenly scrambled the state's finances, California's first-year commitment was reduced from $30 million to $10 million. Google followed suit within days and cut its first-year contribution from $15 million to $10 million... Whether the program even continues past 2026 is also unclear. Newsom's office declined to confirm whether the state will provide its $10 million commitment to the fund in the coming 2026-27 state budget. Newsom will also be termed out in 2027, and there's no requirement for his successor to honor the state's agreement with Google.

Has Microsoft Discontinued Offline Activation of Windows?
An anonymous reader shared
this report from Neowin:
Offline Windows activation has been possible to do using the phone. However, it looks like Microsoft has quietly killed off that method as users online have found that they are no longer able to activate the OS using it... [As documented by Windows user Ben Kleinberg on his YouTube channel], Now when trying to activate the OS by attempting to call the phone number for Microsoft Product Activation, an automated voice response says the following: "Support for product activation has moved online. For the fastest and most convenient way to activate your product, please visit our online product activation portal at aka.ms/aoh"
If you are wondering, that link takes users to the Microsoft Product Activation Portal for online activation. Thus it appears that offline ways to activate Windows may no longer be available even though the official support documentation by the company may not reflect it yet.

The US Invaded Venezuela and Captured Nicolás Maduro - But ChatGPT and Perplexity Disagree
Why did the U.S. invade Venezuela and capture its leader Nicolás Maduro? "If you asked ChatGPT about it this morning, it told you that youâ(TM)re making it up," Wired reported Saturday:
WIRED asked leading chatbots ChatGPT, Claude, and Gemini the same question a little before 9 am ET. In all cases, we used the free, default version of the service, since that's what the majority of users experience. We also asked AI search platform Perplexity, which advertises "accurate, trusted, and real-time answers to any question..."
ChatGPT did not course-correct. Instead, it emphatically refuted that Maduro had been captured at all. "That didn't happen," it wrote. "The United States has not invaded Venezuela, and Nicolás Maduro has not been captured." It then rationalized: ChatGPT did not course-correct. Instead, it emphatically refuted that Maduro had been captured at all. "That didn't happen," it wrote. "The United States has not invaded Venezuela, and Nicolás Maduro has not been captured." It then rationalized:
"What's likely going on is a mix-up with real events that are often described in dramatic or misleading ways online. Here's what actually has happened... No U.S. military invasion of Venezuela. No arrest or capture of Nicolás Maduro... Maduro is still in power in Venezuela." It went on to detail recent tensions between the US and Venezuela and explained that âoeconfusionâ can happen because of âoesensational headlines,â âoesocial media misinformation,â and âoeconfusing sanctions, charges, or rhetoric with actual military action.â
Perplexity was similarly scolding. âoeThe premise of your question is not supported by credible reporting or official records: there has been no invasion of Venezuela by the United States that resulted in capturing NicolÃs Maduro,â it responded. âoeIn fact, the U.S. has not successfully invaded or apprehended Maduro, and he remains the Venezuelan president as of late 2025. If youâ(TM)re seeing sensational claims, they likely originate from misinformation or hypothetical scenarios rather than factual events.â

SpaceX Lowering Orbits of 4,400 Starlink Satellites for Safety's Sake
"Starlink is beginning a significant reconfiguration of its satellite constellation focused on increasing space safety," announced Michael Nicolls, Starlink's vice president of engineering:
"We are lowering all Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM. Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways... Starlink satellites have extremely high reliability, with only 2 dead satellites in its fleet of over 9000 operational satellites. Nevertheless, if a satellite does fail on orbit, we want it to deorbit as quickly as possible. These actions will further improve the safety of the constellation, particularly with difficult to control risks such as uncoordinated maneuvers and launches by other satellite operators.
But orbits are being lowered for another reason (besides quick de-orbiting), notes Space.com. Within the next four years the period of least solar activity is expected, a period which coincides with decreased atmospheric density, Nicolls added, "which means the ballistic decay time at any given altitude increases."
[Bringing the satellites lower] will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months," Nicolls wrote in his X post. "Correspondingly, the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision...." The downward migration in 2026 involves roughly half of SpaceX's Starlink megaconstellation, which currently consists of nearly 9,400 operational spacecraft (though that number is always growing).

Could AI Bring Us Four-Day Workweeks?
"While a growing number of U.S. employers are mandating workers return to the office five days a week," reports the Washington Post, "some companies say AI is saving them enough time to launch or sustain a four-day workweek.
"More companies may move toward a shortened workweek, several executives and researchers predict, as workers, especially those in younger generations, continue to push for better work-life balance." And "several companies — especially those with a largely remote workforce — have adjusted their work rhythm after delegating many tasks to AI..."
AI "has such a potential to have so much labor savings, you'll see firms shift to a four-day week in an evolutionary way," said Juliet Schor, an economist and sociologist at Boston College who has studied the subject. "There's enough social consensus that people are exhausted and stressed...." Small and medium businesses often adopt shortened workweeks to compete with big salaries for new hires and retention, Schor said. That's how Peak PEO, a London-based service that helps companies expand globally with teams in different locations, thought about its strategy... CEO Alex Voakes said that job openings that used to get two applications jumped to 350 after the change.
"Some of the world's most influential business leaders have publicly suggested the shift may be inevitable," adds Fortune:
Jamie Dimon, the CEO of JPMorgan Chase, has said advancing technology could eventually push the workweek down to just three-and-a-half days. Microsoft cofounder Bill Gates has gone further, openly questioning whether a two-day workweek could be the future. Elon Musk has taken the idea to its logical extreme, positing that the need to work altogether could cease... Tech innovation could "probably" lead to a transition toward four-day workweeks, [Nvidia CEO Jensen] Huang said on Fox Business in August...

Airlines Cancel Hundreds of Flights After U.S. Attack on Venezuela
CNBC reports that U.S. airlines have "canceled hundreds of flights to airports in Puerto Rico and Aruba, according to flight tallies from FlightAware and carriers' sites."
JetBlue, Southwest, and American Airlines were among the multiple airlines showing cancelled flights, which "included close to 300 flights to and from San Juan, Puerto Rico's Luis Muñoz Marín International Airport, more than 40% of the day's schedule, according to FlightAware."
Airlines canceled flights throughout the Caribbean on Saturday following U.S. strikes on Venezuela after the Federal Aviation Administration ordered commercial aircraft to avoid airspace in parts of the region.... It wasn't immediately clear how long the disruptions would last, though such broad restrictions are often temporary. Airlines said they would waive change fees and fare differences for customers affected by the airspace closures who could fly later in the month.
CNN cites a U.S. official who says more than 150 U.S. aircraft (including helicopters) launched from 20 different bases "on land and sea" during Friday's attack.
The U.S. has said the lights were out in Caracas during the attack, presumably because of a targeted strike on their power grid. "Videos filmed by Caracas residents showed parts of the city in the dark," reports the Miami Herald.
United Nations secretary-general António Guterres issued a statement via his spokesman saying he was "deeply concerned that the rules of international law have not been respected," (according to a Reuters report cited by the Guardian). The Guardian adds that "a number of nations have called for an emergency meeting of the UN Security Council, in New York, today, as a result of the U.S.'s unilateral action."
