  • NASA Chief Classifies Starliner Flight As 'Type A' Mishap, Says Agency Made Mistakes
    by BeauHD on 20/02/2026 at 7:00 am

    NASA has officially classified Boeing Starliner's 2024 crewed flight as a "Type A" mishap, acknowledging serious technical failures and leadership shortcomings that nearly left astronauts unable to safely return. Administrator Jared Isaacman released (PDF) a 311-page internal report citing flawed decision-making and cultural issues, with the next Starliner flight now planned as uncrewed pending major fixes. Ars Technica reports: As part of the announcement, NASA Administrator Jared Isaacman sent an agency-wide letter that recognized the shortcomings of both Starliner's developer, Boeing, as well as the space agency itself. Starliner flew under the auspices of NASA's Commercial Crew Program, in which the agency procures astronaut transportation services to the International Space Station. "We are taking ownership of our shortcomings," Isaacman said. "Starliner has design and engineering deficiencies that must be corrected, but the most troubling failure revealed by this investigation is not hardware," Isaacman wrote in his letter to the NASA workforce. "It is decision-making and leadership that, if left unchecked, could create a culture incompatible with human spaceflight." Isaacman said there would be "leadership accountability" as a result of the decisions surrounding the Starliner program, but did not say which actions would be taken.

  • Trump Directs US Government To Prepare Release of Files on Aliens and UFOs
    by msmash on 20/02/2026 at 5:00 am

    US President Donald Trump says he will direct US agencies, including the defence department, to "begin the process of identifying and releasing" government files on aliens and extraterrestrial life. From a report: Trump made the declaration in a post on Truth Social, after he accused Barack Obama earlier in the day of revealing classified information when the former president said "aliens are real" on a podcast last week. "He's not supposed to be doing that," Trump told reporters aboard Air Force One, adding: "He made a big mistake." Asked if he also thinks aliens are real, Trump answered: "Well, I don't know if they're real or not." Former US President Obama told podcast host Brian Tyler Cohen that he thinks aliens are real in an interview released last Saturday. "They're real, but I haven't seen them, and they're not being kept in Area 51," Obama said. "There's no underground facility unless there's this enormous conspiracy and they hid it from the president of the United States." Read more of this story at Slashdot.

  • Newborn Chicks Connect Sounds With Shapes Just Like Humans, Study Finds
    by BeauHD on 20/02/2026 at 3:30 am

    An anonymous reader quotes a report from Scientific American: Why does "bouba" sound round and "kiki" sound spiky? This intuition that ties certain sounds to shapes is oddly reliable all over the world, and for at least a century, scientists have considered it a clue to the origin of language, theorizing that maybe our ancestors built their first words upon these instinctive associations between sound and meaning. But now a new study adds an unexpected twist: baby chickens make these same sound-shape connections, suggesting that the link to human language may not be so unique. The results, published today in Science, challenge a long-standing theory about the so-called bouba-kiki effect: that it might explain how humans first tethered meaning to sound to create language. Perhaps, the thinking goes, people just naturally agree on certain associations between shapes and sounds because of some innate feature of our brain or our world. But if the barnyard hen also agrees with such associations, you might wonder if we've been pecking at the wrong linguistic seed. Maria Loconsole, a comparative psychologist at the University of Padua in Italy, and her colleagues decided to investigate the bouba-kiki effect in baby chicks because the birds could be tested almost immediately after hatching, before their brain would be influenced by exposure to the world. The researchers placed chicks in front of two panels: one featured a flowerlike shape with gently rounded curves; the other had a spiky blotch reminiscent of a cartoon explosion. They then played recordings of humans saying either "bouba" or "kiki" and observed the birds' behavior. When the chicks heard "bouba," 80 percent of them approached the round shape first and spent an average of more than three minutes exploring it compared with an average of just under one minute spent exploring the spiky shape. The exploration preferences were flipped when the chicks heard "kiki." Because the tests took place within the chicks' carefully supervised first hours of life outside their eggshell, this association between particular sounds and shapes couldn't have been learned from experience. Instead it may be evidence of an innate perceptual bias that goes back way farther in our evolutionary history than previously believed. "We parted with birds on the evolutionary line 300 million years ago," says Aleksandra Cwiek, a linguist at Nicolaus Copernicus University in Toru, Poland, who was not involved in the study. "It's just mind-blowing." Read more of this story at Slashdot.

  • US Plans Online Portal To Bypass Content Bans In Europe and Elsewhere
    by BeauHD on 20/02/2026 at 2:02 am

    The U.S. State Department is reportedly developing a site called freedom.gov that would let users in Europe and elsewhere access content restricted under local laws, "including alleged hate speech and terrorist propaganda," reports Reuters. Washington views the move as a way to counter censorship. Reuters reports: One source said officials had discussed including a virtual private network function to make a user's traffic appear to originate in the U.S. and added that user activity on the site will not be tracked. Headed by Undersecretary for Public Diplomacy Sarah Rogers, the project was expected to be unveiled at last week's Munich Security Conference but was delayed, the sources said. Reuters could not determine why the launch did not happen, but some State Department officials, including lawyers, have raised concerns about the plan, two of the sources said, without detailing the concerns. The project could further strain ties between the Trump administration and traditional U.S. allies in Europe, already heightened by disputes over trade, Russia's war in Ukraine and President Donald Trump's push to assert control over Greenland. The portal could also put Washington in the unfamiliar position of appearing to encourage citizens to flout local laws. Read more of this story at Slashdot.

  • California's New Bill Requires DOJ-Approved 3D Printers That Report on Themselves
    by BeauHD on 20/02/2026 at 1:25 am

    California's recently-proposed AB-2047 would require 3D printers sold in the state to be DOJ-approved models equipped with "firearm blocking technology," banning non-certified machines after 2029 and criminalizing efforts to bypass the software. Adafruit notes that unlike similar legislation proposed in Washington State and New York, California's version "adds a certification bureaucracy on top: state-approved algorithms, state-approved software control processes, state-approved printer models, quarterly list updates, and civil penalties up to $25,000 per violation." From the report: Assembly Member Bauer-Kahan introduced AB-2047, the "California Firearm Printing Prevention Act," on February 17th. The bill would ban the sale or transfer of any 3D printer in California unless it appears on a state-maintained roster of approved makes and models... certified by the Department of Justice as equipped with "firearm blocking technology." Manufacturers would need to submit attestations for every make and model. The DOJ would publish a list. If your printer isn't on the list by March 1, 2029, it can't be sold. In addition, knowingly disabling or circumventing the blocking software is a misdemeanor. [...] As Michael Weinberg wrote after the New York and Washington proposals dropped⦠accurately identifying gun parts from geometry alone is incredibly hard, desktop printers lack the processing power to run this kind of analysis, and the open-source firmware that runs most machines makes any blocking requirement trivially easy to bypass. The Firearms Policy Coalition flagged AB-2047 on X, and the reactions tell you everything. Jon Lareau called it "stupidity on steroids," pointing out that a simple spring-shaped part has no way of revealing its intended use. The Foundry put it plainly: "Regulating general-purpose machines is another. AB-2047 would require 3D printers to run state-approved surveillance software and criminalize modifying your own hardware." Read more of this story at Slashdot.

  • Google Announces Gemini 3.1 Pro For 'Complex Problem-Solving'
    by BeauHD on 20/02/2026 at 12:45 am

    Google has introduced Gemini 3.1 Pro, a reasoning-focused upgrade aimed at more complex problem-solving. 9to5Google reports: This .1 increment is a first for Google, with the past two generations seeing .5 as the mid-year model update. (2.5 Pro was first announced in March and saw further updates in May for I/O.) Google says Gemini 3.1 Pro "represents a step forward in core reasoning." The "upgraded core intelligence" that debuted last week with Gemini 3 Deep Think is now available in Gemini 3.1 Pro for more users. This model achieves an ARC-AGI-2 score of 77.1%, or "more than double the reasoning performance of 3 Pro." This "advanced reasoning" translates to practical applications like when "you're looking for a clear, visual explanation of a complex topic, a way to synthesize data into a single view, or bringing a creative project to life." 3.1 Pro is designed for tasks where a simple answer isn't enough, taking advanced reasoning and making it useful for your hardest challenges.
