How NASA Saved a Camera From 370 Million Miles Away

화, 2025/07/22 - 10:00오후
An anonymous reader quotes a report from Phys.org: The mission team of NASA's Jupiter-orbiting Juno spacecraft executed a deep-space move in December 2023 to repair its JunoCam imager to capture photos of the Jovian moon Io. Results from the long-distance save were presented during a technical session on July 16 at the Institute of Electrical and Electronics Engineers Nuclear & Space Radiation Effects Conference in Nashville. JunoCam is a color, visible-light camera. The optical unit for the camera is located outside a titanium-walled radiation vault, which protects sensitive electronic components for many of Juno's engineering and science instruments. This is a challenging location because Juno's travels carry it through the most intense planetary radiation fields in the solar system. While mission designers were confident JunoCam could operate through the first eight orbits of Jupiter, no one knew how long the instrument would last after that. Throughout Juno's first 34 orbits (its prime mission), JunoCam operated normally, returning images the team routinely incorporated into the mission's science papers. Then, during its 47th orbit, the imager began showing hints of radiation damage. By orbit 56, nearly all the images were corrupted. While the team knew the issue might be tied to radiation, pinpointing what was specifically damaged within JunoCam was difficult from hundreds of millions of miles away. Clues pointed to a damaged voltage regulator that was vital to JunoCam's power supply. With few options for recovery, the team turned to a process called annealing, where a material is heated for a specified period before slowly cooling. Although the process is not well understood, the idea is that heating can reduce defects in the material. Soon after the annealing process finished, JunoCam began cranking out crisp images for the next several orbits. But Juno was flying deeper and deeper into the heart of Jupiter's radiation fields with each pass. By orbit 55, the imagery had again begun showing problems. "After orbit 55, our images were full of streaks and noise," said JunoCam instrument lead Michael Ravine of Malin Space Science Systems. "We tried different schemes for processing the images to improve the quality, but nothing worked. With the close encounter of Io bearing down on us in a few weeks, it was Hail Mary time: The only thing left we hadn't tried was to crank JunoCam's heater all the way up and see if more extreme annealing would save us." Test images sent back to Earth during the annealing showed little improvement in the first week. Then, with the close approach of Io only days away, the images began to improve dramatically. By the time Juno came within 930 miles (1,500 kilometers) of the volcanic moon's surface on Dec. 30, 2023, the images were almost as good as the day the camera launched, capturing detailed views of Io's north polar region that revealed mountain blocks covered in sulfur dioxide frosts rising sharply from the plains and previously uncharted volcanoes with extensive flow fields of lava. To date, the solar-powered spacecraft has orbited Jupiter 74 times. Recently, the image noise returned during Juno's 74th orbit.

US Signals Intention To Rethink Job H-1B Lottery

화, 2025/07/22 - 9:00오후
The US Department of Homeland Security (DHS) and the US Citizenship and Immigration Services (USCIS) intend to reevaluate how H-1B visas are issued, according to a regulatory filing. From a report: The notice, filed on Thursday with the US Office of Management and Budget's Office of Information and Regulatory Affairs (OIRA), seeks the statutory review of a proposed rule titled "Weighted Selection Process for Registrants and Petitioners Seeking To File Cap-Subject H-1B Petitions." Once the review is complete, which could be a matter of days or weeks, the text of the rule is expected to be published in the US Federal Register. Based on the rule title, it appears the government intends to change the system for allocating H-1B visas the current lottery to some system that will favor applicants who meet specified criteria, possibly related to skills. The H-1B visa program, which reached its Fiscal 2026 cap on Friday, allows skilled guest workers to come work in the US. As of 2019, there were about 600,000 H-1B workers in the US, according to USCIS. The foreign worker program is beloved by technology companies, ostensibly to hire talent not readily available from American workers. But H-1B -- along with the Optional Practical Training (OPT) program -- has long been criticized for making it easier to undercut US worker wages, limiting labor rights for immigrants, and for persistent abuse of the rules by outsourcing companies.

ChatGPT Users Send 2.5 Billion Prompts a Day

화, 2025/07/22 - 7:00오후
ChatGPT now handles 2.5 billion prompts daily, with 330 million from U.S. users. This surge marks a doubling in usage since December when OpenAI CEO Sam Altman said that users send over 1 billion queries to ChatGPT each day. TechCrunch reports: These numbers show just how ubiquitous OpenAI's flagship product is becoming. Google's parent company, Alphabet, does not release daily search data, but recently revealed that Google receives 5 trillion queries per year, which averages to just under 14 billion daily searches. Independent researchers have found similar trends. Neil Patel of NP Digital estimates that Google receives 13.7 billion searches daily, while research from SparkToro and Datos -- two digital marketing companies -- estimates that the figure is around 16.4 billion per day.

Climate Change Is Making Fire Weather Worse for World's Forests

화, 2025/07/22 - 4:00오후
An anonymous reader shares a report: In 2023 and 2024, the hottest years on record, more than 78 million acres of forests burned around the globe. The fires sent veils of smoke and several billion tons of carbon dioxide into the atmosphere, subjecting millions of people to poor air quality. Extreme forest-fire years are becoming more common because of climate change, new research suggests. "Climate change is loading the dice for extreme fire seasons like we've seen," said John Abatzoglou, a climate scientist at the University of California Merced. "There are going to be more fires like this." The area of forest canopy lost to fire during 2023 and 2024 was at least two times greater than the annual average of the previous nearly two decades, according to a new study published Monday in the journal Proceedings of the National Academy of Sciences. The researchers used imagery from the LANDSAT satellite network to determine how tree cover had changed from 2002 to 2024, and compared that with satellite detections of fire activity to see how much canopy loss was because of fire. Globally, the area of land burned by wildfires has decreased in recent decades, mostly because humans are transforming savannas and grasslands into less flammable landscapes. But the area of forests burned has gone up.

At Least 750 US Hospitals Faced Disruptions During Last Year's CrowdStrike Outage, Study Finds

화, 2025/07/22 - 1:20오후
At least 759 US hospitals experienced network disruptions during the CrowdStrike outage on July 19, 2024, with more than 200 suffering outages that directly affected patient care services, according to a study published in JAMA Network Open by UC San Diego researchers. The researchers detected disruptions across 34% of the 2,232 hospital networks they scanned, finding outages in health records systems, fetal monitoring equipment, medical imaging storage, and patient transfer platforms. Most services recovered within six hours, though some remained offline for more than 48 hours. CrowdStrike dismissed the study as "junk science," arguing the researchers failed to verify whether affected networks actually ran CrowdStrike software. The researchers defended their methodology, noting they could scan only about one-third of America's hospitals, suggesting the actual impact may have been significantly larger.

Can AI Think - and Should It? What It Means To Think, From Plato To ChatGPT

화, 2025/07/22 - 12:30오후
alternative_right shares a report from The Conversation: Greek philosophers may not have known about 21st-century technology, but their ideas about intellect and thinking can help us understand what's at stake with AI today. Although the English words "intellect" and "thinking" do not have direct counterparts in the ancient Greek, looking at ancient texts offers useful comparisons. In "Republic," for example, Plato uses the analogy of a "divided line" separating higher and lower forms of understanding. Plato, who taught in the fourth century BCE, argued that each person has an intuitive capacity to recognize the truth. He called this the highest form of understanding: "noesis." Noesis enables apprehension beyond reason, belief or sensory perception. It's one form of "knowing" something -- but in Plato's view, it's also a property of the soul. Lower down, but still above his "dividing line," is "dianoia," or reason, which relies on argumentation. Below the line, his lower forms of understanding are "pistis," or belief, and "eikasia," imagination. Pistis is belief influenced by experience and sensory perception: input that someone can critically examine and reason about. Plato defines eikasia, meanwhile, as baseless opinion rooted in false perception. In Plato's hierarchy of mental capacities, direct, intuitive understanding is at the top, and moment-to-moment physical input toward the bottom. The top of the hierarchy leads to true and absolute knowledge, while the bottom lends itself to false impressions and beliefs. But intuition, according to Plato, is part of the soul, and embodied in human form. Perceiving reality transcends the body -- but still needs one. So, while Plato does not differentiate "intelligence" and "thinking," I would argue that his distinctions can help us think about AI. Without being embodied, AI may not "think" or "understand" the way humans do. Eikasia -- the lowest form of comprehension, based on false perceptions -- may be similar to AI's frequent "hallucinations," when it makes up information that seems plausible but is actually inaccurate. Aristotle, Plato's student, sheds more light on intelligence and thinking. In "On the Soul," Aristotle distinguishes "active" from "passive" intellect. Active intellect, which he called "nous," is immaterial. It makes meaning from experience, but transcends bodily perception. Passive intellect is bodily, receiving sensory impressions without reasoning. We could say that these active and passive processes, put together, constitute "thinking." Today, the word "intelligence" holds a logical quality that AI's calculations may conceivably replicate. Aristotle, however, like Plato, suggests that to "think" requires an embodied form and goes beyond reason alone. Aristotle's views on rhetoric also show that deliberation and judgment require a body, feeling and experience. We might think of rhetoric as persuasion, but it is actually more about observation: observing and evaluating how evidence, emotion and character shape people's thinking and decisions. Facts matter, but emotions and people move us -- and it seems questionable whether AI utilizes rhetoric in this way. Finally, Aristotle's concept of "phronesis" sheds further light on AI's capacity to think. In "Nicomachean Ethics," he defines phronesis as "practical wisdom" or "prudence." "Phronesis" involves lived experience that determines not only right thought, but also how to apply those thoughts to "good ends," or virtuous actions. AI may analyze large datasets to reach its conclusions, but "phronesis" goes beyond information to consult wisdom and moral insight.

SoftBank and Open AI's $500 Billion AI Project Struggles To Get Off Ground

화, 2025/07/22 - 10:40오전
The $500 billion Stargate AI project announced by SoftBank and OpenAI at the White House six months ago has failed to complete a single data center deal and sharply scaled back its near-term plans. The venture, which originally pledged to invest $100 billion "immediately," now aims to build one small data center by year-end, likely in Ohio, according to WSJ. SoftBank and OpenAI have disagreed over crucial partnership terms, including site locations. OpenAI has proceeded independently, signing a deal with Oracle worth more than $30 billion annually starting within three years. That agreement totals 4.5 gigawatts of capacity and would consume power equivalent to more than two Hoover Dams. Combined with a smaller CoreWeave deal, OpenAI has secured nearly as much data center capacity as Stargate promised for this year. SoftBank invested $30 billion in OpenAI earlier this year as part of the infrastructure partnership plans.

FCC To Eliminate Gigabit Speed Goal, Scrap Analysis of Broadband Prices

화, 2025/07/22 - 10:00오전
FCC Chairman Brendan Carr is proposing (PDF) to roll back key Biden-era broadband policies, scrapping the long-term gigabit speed goal, halting analysis of broadband affordability, and reinterpreting deployment standards in a way that favors industry metrics over consumer access. The proposal, which is scheduled for a vote on August 7, narrows the scope of Section 706 evaluations to focus on whether broadband is being deployed rather than whether it's affordable or universally accessible. Ars Technica reports: The changes will make it easier for the FCC to give the broadband industry a passing grade in an annual progress report. FCC Chairman Brendan Carr's proposal would give the industry a thumbs-up even if it falls short of 100 percent deployment, eliminate a long-term goal of gigabit broadband speeds, and abandon a new effort to track the affordability of broadband. Section 706 of the Telecommunications Act requires the FCC to determine whether broadband is being deployed "on a reasonable and timely basis" to all Americans. If the answer is no, the US law says the FCC must "take immediate action to accelerate deployment of such capability by removing barriers to infrastructure investment and by promoting competition in the telecommunications market." Generally, Democratic-led commissions have found that the industry isn't doing enough to make broadband universally available, while Republican-led commissions have found the opposite. Democratic-led commissions have also periodically increased the speeds used to determine whether advanced telecommunications capabilities are widely available, while Republican-led commissioners have kept the speed standards the same.

Spotify Publishes AI-Generated Songs From Dead Artists Without Permission

화, 2025/07/22 - 9:20오전
Spotify was found publishing AI-generated songs on the official pages of deceased artists like Blaze Foley and Guy Clark -- without permission from their estates or labels. The tracks, flagged for deceptive content and now removed, were uploaded via TikTok's SoundOn distribution platform. "We've flagged the issue to SoundOn, the distributor of the content in question, and it has been removed for violating our Deceptive Content policy," a Spotify spokesperson told 404 Media. From the report: McDonald, who decided to originally upload Foley's music to Spotify in order to share it with more people, told me he never thought that an AI-generated track could appear on Foley's page without his permission. "It's harmful to Blaze's standing that this happened," he said. "It's kind of surprising that Spotify doesn't have a security fix for this type of action, and I think the responsibility is all on Spotify. They could fix this problem. One of their talented software engineers could stop this fraudulent practice in its tracks, if they had the will to do so. And I think they should take that responsibility and do something quickly." McDonald's suggested fix is not allowing any track to appear on an artist's official Spotify page without allowing the page owner to sign off on it first. "Any real Blaze fan would know, I think, pretty instantly, that this is not Blaze or a Blaze recording," he said. "Then the harm is that the people who don't know Blaze go to the site thinking, maybe this is part of Blaze, when clearly it's not. So again, I think Spotify could easily change some practices. I'm not an engineer, but I think it's pretty easy to stop this from happening in the future."

Alaska Airlines Resumes Operations After System Glitch Grounds All Flights

화, 2025/07/22 - 8:40오전
Alaska Airlines and Horizon Air grounded all flights Sunday night due to a major IT outage, prompting a system-wide FAA ground stop that lasted until early Monday. Although operations have since resumed, passengers are still facing delays and residual disruptions. Gizmodo reports: The airline requested a system-wide ground stop from federal aviation authorities at about 11 p.m. ET on Sunday night. That stop remained in effect until around 2 a.m. ET Monday, when the Federal Aviation Administration confirmed it had been lifted. But disruptions didn't end there. Alaska warned passengers to brace for likely delays throughout the day. [...] The FAA's website listed the stop as applying to all Alaska Airlines aircraft. Gizmodo notes that the incident comes nearly a year after the massive 2024 CrowdStrike crash, which has become known as the largest IT outage in history. "The July 2024 outage brought down an estimated 8.5 million Microsoft Windows systems running CrowdStrike's Falcon Sensor software, disrupting everything from hospitals and airports to broadcast networks." "There's no word yet from Alaska on whether the outage ties into a broader software problem, but the timing, almost exactly a year after the CrowdStrike crash, isn't going unnoticed on social media, with users wondering if the events are related."

Xbox Cloud Games Will Soon Follow You Across Xbox, PC, and Windows Handhelds

화, 2025/07/22 - 5:40오전
Microsoft is rolling out updates to the Xbox PC app and consoles that sync your cloud gaming history and progress across devices, making it easier to resume cloud-playable titles on PCs, handhelds, and other Xbox hardware. The Verge reports: Cloud-playable games are now starting to show inside play history or the library on the Xbox PC app. "This includes all cloud playable titles, even console exclusives spanning from the original Xbox to Xbox Series X|S, whether you own the title or access it through Game Pass," explains Lily Wang, product manager of Xbox experiences. Your recent games, including cloud ones, will soon follow you across devices -- complete with cloud-powered game saves. So if you played an Xbox game on your console that's not natively available on PC, it will still show up in your recent games list and be playable through Xbox Cloud Gaming on Windows. Cloud-playable games on the Xbox PC app can be found from a new filter in the library section, and a new "play history" section will appear at the end of the "jump back in" list on the home screen of the Xbox PC app. "While the large tiles highlight games you've recently played on your current device, the play history tile shows games you've played across any Xbox device, making it easy to pick up where you left off," says Wang. This same play history section will appear on the main Xbox console interface, too -- which could mean we'll eventually see PC games listed here and playable through Xbox Cloud Gaming.

Weak Password Allowed Hackers To Sink a 158-Year-Old Company

화, 2025/07/22 - 5:00오전
An anonymous reader quotes a report from the BBC: One password is believed to have been all it took for a ransomware gang to destroy a 158-year-old company and put 700 people out of work. KNP -- a Northamptonshire transport company -- is just one of tens of thousands of UK businesses that have been hit by such attacks. Big names such as M&S, Co-op and Harrods have all been attacked in recent months. The chief executive of Co-op confirmed last week that all 6.5 million of its members had had their data stolen. In KNP's case, it's thought the hackers managed to gain entry to the computer system by guessing an employee's password, after which they encrypted the company's data and locked its internal systems. KNP director Paul Abbott says he hasn't told the employee that their compromised password most likely led to the destruction of the company. "Would you want to know if it was you?" he asks. "We need organizations to take steps to secure their systems, to secure their businesses," says Richard Horne CEO of the National Cyber Security Centre (NCSC) -- where Panorama has been given exclusive access to the team battling international ransomware gangs. A gang of hackers, known as Akira, broke into the company's system and demanded a payment to restore the data. "The hackers didn't name a price, but a specialist ransomware negotiation firm estimated the sum could be as much as 5 million pounds," reports the BBC. "KNP didn't have that kind of money. In the end all the data was lost, and the company went under."

Advanced Version of Gemini With Deep Think Officially Achieves Gold-Medal Standard at the International Mathematical Olympiad

화, 2025/07/22 - 4:08오전
An anonymous reader shares a blog post: The International Mathematical Olympiad is the world's most prestigious competition for young mathematicians, and has been held annually since 1959. Each country taking part is represented by six elite, pre-university mathematicians who compete to solve six exceptionally difficult problems in algebra, combinatorics, geometry, and number theory. Medals are awarded to the top half of contestants, with approximately 8% receiving a prestigious gold medal. Recently, the IMO has also become an aspirational challenge for AI systems as a test of their advanced mathematical problem-solving and reasoning capabilities. Last year, Google DeepMind's combined AlphaProof and AlphaGeometry 2 systems achieved the silver-medal standard, solving four out of the six problems and scoring 28 points. Making use of specialist formal languages, this breakthrough demonstrated that AI was beginning to approach elite human mathematical reasoning. This year, we were amongst an inaugural cohort to have our model results officially graded and certified by IMO coordinators using the same criteria as for student solutions. Recognizing the significant accomplishments of this year's student-participants, we're now excited to share the news of Gemini's breakthrough performance. An advanced version of Gemini Deep Think solved five out of the six IMO problems perfectly, earning 35 total points, and achieving gold-medal level performance.

Microsoft Releases Emergency Patches for Actively Exploited SharePoint Zero-Days

화, 2025/07/22 - 12:23오전
Microsoft has released emergency security updates for two actively exploited zero-day vulnerabilities in SharePoint, tracked as CVE-2025-53770 and CVE-2025-53771, that have compromised servers worldwide in what researchers call "ToolShell" attacks. The U.S. Cybersecurity and Infrastructure Security Agency warned over the weekend that hackers were exploiting the vulnerabilities to gain remote code execution on on-premises SharePoint installations, while Microsoft has not yet provided patches for all affected versions. The vulnerabilities allow hackers to steal private digital keys from SharePoint servers without requiring credentials, enabling them to plant malware and access stored files and data. Eye Security, which first identified the attacks on Saturday, found dozens of actively exploited servers and warned that SharePoint's integration with Outlook, Teams, and OneDrive could enable further network compromise. Researcher Silas Cutler at cybersecurity firm Censys estimated more than 10,000 companies with SharePoint servers were at risk, with the largest concentrations in the United States, Netherlands, United Kingdom, and Canada. Microsoft released patches for SharePoint 2019 and Subscription Edition but is still working on fixes for SharePoint Server 2016. Administrators must install available updates immediately and rotate machine keys to prevent re-compromise, according to Microsoft's security guidance.
