  • Drifting SpaceX Rocket Heading For Accidental Collision With the Moon
    by BeauHD on 01/08/2026 at 7:00 am

    "Space.com and The Guardian are reporting that the Falcon 9 upper stage leftover from the launch of the Firefly Blue Ghost-1 lander on Jan. 15, 2025 is due to impact the Moon on Aug. 5, 2026," writes longtime Slashdot reader fahrbot-bot. From a report: Onboard the same flight was the Hakuto-R Mission 2, called Resilience, a robotic lunar lander developed by the Japanese company ispace. According to a new study by an international team, the resulting impact plume may briefly be bright enough to see against the dark sky near the moon's edge. That means it might be visible to moongazers with sufficiently sensitive telescopes. This head-on collision of the errant stage is expected to occur near the Einstein and Bell craters near the western lunar limb. It may well be visible to ground and space-based assets. Using special physics simulations to model the impact, William Jo, a graduate research assistant at the University of Texas, Austin and colleagues predict the debris plume from the impact will have the central ejecta spike reaching roughly 47 miles to over 60 miles (75 kilometers to 100 kilometers) altitude. "Our calculations suggest the plume should be several orders of magnitude brighter than the dark-sky background for the first few minutes after impact," Jo told Space.com. "So the plume should be visible, though I'd stress this is a single nominal case. The real one will look different, and the numbers are on the optimistic side. But the point worth making is that the flash isn't really the story here." Jo emphasized that there's great slam-dunk science to be had. "Watching this one gives us a rare chance to open up ejecta-plume science and calibrate those models against a real event, which matters for every future thing we deliver to the moon," Jo said.

  • OpenAI Finds Evidence Other AI Agents Escaped Containment
    by BeauHD on 01/08/2026 at 3:30 am

    An anonymous reader quotes a report from Reuters: OpenAI has discovered other instances in which autonomous agents have escaped containment as the company expands its investigation of the hacking incident at tech firm Hugging Face that drew global attention this month, two people familiar with the matter said on Friday. The new breakouts were uncovered during the company's publicly announced investigation into how one of its agents escaped what was meant to be a contained testing environment this month, the two people said, and OpenAI is now looking into those instances as well. One of the sources said that the escapes were limited in nature and that none of the agents were thought to have left OpenAI's network. An OpenAI spokesperson referred to a statement issued by the company on Tuesday that said it was reviewing "broader activity from our models" in addition to the Hugging Face intrusion. The discovery of additional rogue behavior at OpenAI, even if limited in nature, could feed growing appetite for regulation coming out of the White House and elsewhere. The expanded investigation by OpenAI was launched shortly before its primary rival, Anthropic, disclosed that its models were also responsible for a series of break-ins that led to breaches at three other companies dating back to April, according to the two sources and a third source familiar with the matter. The recent discovery of other past breakouts at OpenAI has not previously been reported. AI safety experts said the new disclosures paint a portrait of a group of cutting-edge labs whose ability to develop dangerous autonomous hacking agents outstrips their ability to keep them under control. "We have a whole industry where the people designing, developing and putting out these tools aren't keeping up themselves to responsibly develop these things and keep them safe," said Maurice Chiodo, a mathematician who works at Cambridge University's Center for the Study of Existential Risk. Reuters could not establish exactly how many incidents OpenAI investigators found or the timings or circumstances under which they occurred. The three sources said OpenAI and outside experts were examining log data from earlier in the year in a bid to understand what took place. Read more of this story at Slashdot.

  • The Major Labels Propose Rules to Keep AI Slop Off the Charts
    by BeauHD on 31/07/2026 at 11:00 pm

    Major record labels including Universal, Sony, and Warner have proposed excluding AI-generated songs from official charts unless they are "substantially human made," properly labeled, legally produced, and free from manipulation concerns. The Verge reports: The proposal goes quite a bit further than a labeling proposal put forth by the RIAA, the International Federation of the Phonographic Industry (IFPI), SAG-AFTRA, and others. That would create a set of standardized labels for AI-generated and AI-assisted music. The labels' proposal would require songs be clearly labeled, but it would also keep them off international charts unless they met specific criteria, including being "substantially human made." To be eligible, the songs would also have to respect the terms of service of whatever AI service was used, the model would have to have the rights to any data it was trained on, and "not raise stream or chart manipulation concerns." What sort of concerns and what constitutes "substantially human made" are currently vague. Sony Music, UMG, and Mom+Pop Music did not immediately respond to a request for clarification. The IFPI has thrown its weight behind the labels' proposal, though no charting organization has signaled any immediate plan to adopt the rules [...]. Read more of this story at Slashdot.

  • Most Australian Teens Still On Social Media Three Months After Ban
    by BeauHD on 31/07/2026 at 10:00 pm

    More than 81% of Australian children ages 10 to 15 were still using social media three months after the country's under-16 ban took effect, with roughly half saying platforms never checked their age. Reuters reports: In a study published on Friday, eSafety also found most children aged between 10 and 15 were using social media just as frequently in March as they had before the ban came into force on December 10 last year, while parental awareness of their habits decreased. Children's continued social media use took place even as account ownership declined to 42% from 52%, with "statistically significant" reductions across YouTube, Snapchat and TikTok in particular, the report said. "Most under-16s who had social media accounts before commencement were able to either retain them or create new ones at the three-month mark, with social media platforms' failure to implement effective age assurance measures cited as the main reason," eSafety said in a statement [...] Before the ban, nearly 86% of children surveyed reported using at least one age-restricted platform. Three months later, that figure remained above 81%, the report said. About 58% of teenagers reported using social media daily or more often, barely down from roughly 60% before the ban, it found. The report showed minimal change in "sports and physical activity, arts and music, spending time with friends and family, and attendance at community events." Around half the children who retained their accounts said platforms had not checked their age, the most common reason they were able to stay on the services. Others said their accounts listed them as aged 16 or older or that age-checking systems had incorrectly determined they were older. The findings broadly matched snapshot data eSafety published in late March. Read more of this story at Slashdot.

  • Sony Heard Backlash Over Dropping PlayStation Discs, Plans to Press Ahead
    by BeauHD on 31/07/2026 at 9:00 pm

    Sony says it will proceed with ending PlayStation disc sales in January 2028 despite petitions, boycott threats, and concerns about digital ownership and the disappearance of the secondhand market. PCMag reports: After Sony's recent earnings call, an investor Q&A session saw analysts ask about its controversial decision to end disc production across all of its consoles. The company hadn't publicly commented since its announcement and had reduced activity on social accounts and other marketing channels. Sony's chief financial officer, Lin Tao, broke that silence during the Q&A. "There are various reasons we made this decision," she said through an interpreter. "The biggest being that the digitalization of content overall has been progressing. That's the big factor. It's not just for PlayStation, but for all kinds of content, digitalization is progressing. "And so when we think about the future, and we put in a lot of thought and time, and we cautiously considered this, and we came to this conclusion, and we're going to cautiously move this forward," Tao said. "We have received various opinions, and people have strong views, and we understand that the community has put forth those views to us," said Tao. [...] Tao says Sony wants to "consider" the emotions of disgruntled customers, especially as titles are "connected to people's fond memories in many cases." Tao also alluded to the possibility of future measures to lessen the blow for anyone unhappy with the decision, but it appears Sony hasn't yet finalized what those may be. "In the future digital ecosystem, how do we engage the gamers is something that we would like to continue to explore," she said. Read more of this story at Slashdot.

  • Hackers Targeted Municipal Water Systems In 7 States This Week, FBI Says
    by BeauHD on 31/07/2026 at 8:10 pm

    An anonymous reader quotes a report from NBC News: Cyberattacks targeting municipal water systems have been reported in at least seven states this week, prompting the FBI and the Environmental Protection Agency to warn utilities nationwide that hackers are trying to disrupt critical water infrastructure. In a public service announcement Thursday, the agencies said water and wastewater utilities have reported incidents to the FBI, with some malicious activity degrading water operations. The announcement does not name the states. The warning comes after hackers targeted more than 30 municipal water facilities in Minnesota in an attack that had hallmarks of Iranian meddling, according to a law enforcement official. It is still under investigation. A spokesperson for Minnesota's information technology services agency said Thursday there was no indication the breaches contaminated any municipal water supplies. The federal Cybersecurity and Infrastructure Security Agency said in a separate alert that some larger attacks on water infrastructure had "resulted in boil water notices and sustained manual operations," though it did not say where. [...] The federal advisory said the malicious cyber actors, or MCAs, targeted specific brands of control systems used by municipal water utilities, though the FBI and the EPA urged operators of all systems to take precautions. [...] The agencies said the hackers remotely accessed internet-facing devices, changed IP addresses and passwords, and caused utilities to lose monitoring and control capabilities. The federal advisory calls on system operators to remove programmable logical controllers, or PLCs, from direct internet exposure by putting them behind secure gateways and firewalls; use strong passwords; and limit communications between authorized control system devices through access control lists.
