It's not "someone" it's The International Group for Historic Aircraft Recovery (TIGHAR), again. It's always TIGHAR, which interprets every single rock or bit of rubbish ever found on Nikumaroro (called Gardner Island at the time of Earhart's disappearance), while ignoring that the island has been intermittently inhabited for well over a century. TIGHAR has been "finding Earhart" since 1993.

Comment More Paper Reactors (Score 4, Insightful) 189

From Admiral Rickover's 1953 'Paper Reactor' memo, "An academic reactor or reactor plant almost always has the following basic characteristics: 1. It is simple. 2 It is cheap. 3.It is light. 4. It can be built very quickly. 5. It is very flexible in purpose (“omnibus reactor”). 6. Very little development is required. It will use mostly “off-the-shelf” components. 7. The reactor is in the study phase. It is not being built now." Time will, of course, prove the final test as to whether these "microreactor experiments" to produce a "compact, transportable microreactor" will successfully " fast-track the path from lab bench to commercial rollout" and eventually " support applications ranging from remote communities to mining operations and data centers" and "replace disel generators". But I wouldn't bet on it.

Submission + - World's first nuclear microreactor test bed launches at Idaho National Lab (interestingengineering.com)

An anonymous reader writes: The race to dominate next-gen nuclear power just hit ignition at Idaho’s Demonstration of Microreactor Experiments.

The Department of Energy has conditionally selected Westinghouse and Radiant to conduct the first fueled experiments at the DOME, a new test bed at Idaho National Laboratory.

Slated to launch as early as spring 2026, the experiments mark a global first—offering U.S. developers a high-stakes proving ground to accelerate the commercialization of advanced microreactors.

Submission + - 1.5M sq km of sea ice is missing near Antarctica. All climate models were wrong (joannenova.com.au)

An anonymous reader writes: Something huge is happening around Antarctica and the experts didn’t see it coming

More than a million square kilometers of ice has gone:

Since 2015, the continent has shed sea ice equivalent to the area of Greenland. Researchers call it the largest environmental shift detected anywhere on Earth in recent decades. –– Earth dot com

Everything about Antarctica has defied the experts. For years Antarctic sea ice expanded when it wasn’t supposed to. Then, suddenly in 2016 the sea ice around Antarctica dramatically started to shrink, and that wasn’t supposed to happen either. Scientists wondered at the time if it was just a temporary blip, but then it got even smaller. Holes in the sea ice “as big as Switzerland” have started to appear for the first time since the mid 1970s.

To explain this mystery (that was rarely mentioned) a new paper suggests the salinity of surface waters has changed. We’re not just talking about a small piece of ocean, this is everything south of 50. For decades, the surface of the polar Southern Ocean was getting less salty — an “expected response to a warming climate” they said that started in about 1980, “however, this trend reversed abruptly after 2015”.

So as news seeps out this week that there is a “dangerous feedback loop” where shrinking ice is warming the ocean, bear in mind that the experts also admit this is “completely unexpected” which is their way of saying “the models were wrong”. Carbon dioxide was not supposed to do this.

Comment Useless at finding media (Score 1) 248

I read a great deal, particularly speculative fiction. I've tried repeatedly to use various AI tools to track down a short story or book where I can remember details of the story, and perhaps the rough publishing date, but not the title, author, or publisher.

AI appears to be utterly useless for this. It will either come up empty and make vague suggestions, like "Look at fantasy recommendations for the date range you've provided". Or worse, it will focus on the wrong book (say, one published in the 2020s, when I explicitly stated that the book was published in the 1990s) and keep insisting that's the closest match. Even character names or other proper nouns don't seem to work. Telling it to exclude certain titles or authors fails reliably.

When asking similar questions on stories I do remember the details of, getting it to "find" something, it needs to be provided with enough unique information that the story in question could readily be looked up. While it seems like the sort of thing AI ought to be useful for, the only stories it seems to be able to reliably find are very popular ones, even when searching for 21st century works.

I was under the impression that most LLMs are mechanical turks - not in an immediate sense, but in the sense that a lot of workers around the world were involved in annotating the datasets LLMs are trained on.[1] So, from that perspective, what an LLM is doing is outsourcing (in time and space) your conversation to a random person using the internet. Insofar as there's thinking involved, what you're getting are reflections of the thinking involved in building the Chinese Room in the first place.

Yep. Much like his endless Full Self-Driving promises to Tesla shareholders, Musk's promises of "Mars Real Soon" are vaporware, even moreso than the lunar lander services he's been paid for. This will be more wealth transfer, done at the expense of far more productive research and science.

...and I don't just mean "rocket go boom".

SpaceX seems to largely have Booster working. Yes, they lost this one, intentionally pushing some limits on the reentry.

With Ship, Flights 4, 5, and 6 all managed controlled splashdowns. With Flight 7, SpaceX moved to Block2 Ship. Flight 7 was lost due to an internal fuel leak, Flight 8 due to Ship engine failure, and now Flight 9 has been lost with an apparent internal fuel leak, again. For whatever reason, Block 2 doesn't appear to be up to the challenge.

Comment What is the benefit to the American public? (Score 1) 164

Historically corporations have been permitted to exist because they can be an effective way of getting objectively desirable things done. Things like shareholder value and market capitalization are at best orthogonal to whatever public goods they may produce. Look at the top ten US companies by market cap: Apple, Microsoft, Nvidia, Amazon, Google, Facebook, Berkshire Hathaway, Tesla, UnitedHealth Group, and Johnson & Johnson. Most of them are widely hated. The assassination of United Health's CEO was celebrated more than mourned. Of them all, Berkshire Hathaway has the least negatives... and it is largely the opposite of what's described in the article. Innovation may lead to 800 lb corporate gorillas, but that doesn't make having 800 lb gorillas desireable.

Comment Spirt AeroSystems for the telco sector (Score 4, Interesting) 28

Back in 2005 Boeing spun off a lot of its parts production to a newly created company, Mid-Western Aircraft System (later renamed Spirit) to an investment management firm. The idea was clearly (although I don't know that I've ever seen a company spokecritter admit it) to have Spirit, under investment firm management, cut every corner possible to squeeze out more profits. Fast forward two decades, and Boeing is buying Spirit, because cutting corners didn't actually work. Looking at AT&T's announcement (https://about.att.com/story/2025/lumen-mass-markets-fiber-business.html), you can see the same plan taking form. "After closing the transaction with Lumen, the Company plans to sell partial ownership of NetworkCo to an equity partner that will co-invest in the ongoing business. AT&T expects to identify an equity partner and close a transaction within approximately 6-12 months of closing the transaction with Lumen. Upon closing a transaction with an equity partner, the Company expects NetworkCo will be deconsolidated from AT&T’s financial statements and operate as a wholesale commercial open access platform, providing fiber access services to AT&T as the anchor tenant. All acquired Lumen Mass Markets fiber customers will remain AT&T customers." I.e. "NetworkCo" will try to cut every corner and squeeze every penny, but it won't be "AT&T" doing it.

Comment The ever-popular '18 months' (Score 1) 46

"Altman said the goal is to release a device by late next year." Eighteen months is always the perfect timeframe for BS and hype. It's close enough that people who want to believe, or are easily persuadable will tell themselves "that's real soon!" and act (and buy) accordingly. But it is simultaneously far enough out that there is plenty of time for "no one could have seen this coming!" delays or changes in the overall economic climate. Alternatively, it is also far enough that if Altman just stops talking about it in a few months, in 18 months hardly anyone will even remember, and even fewer will care.
