  • WHO Declares Ebola Outbreak a Global Health Emergency
    by BeauHD on 18/05/2026 at 3:00 pm

    An anonymous reader quotes a report from the New York Times: The World Health Organization declared on Saturday that the spread of the Ebola virus in the Democratic Republic of Congo and Uganda was a global health emergency. The announcement was made a day after Africa's leading public health authority reported that an outbreak in a province in the northeast of the country was linked to dozens of suspected deaths. By Saturday, cases had also been confirmed in Kampala, the capital of Uganda, the W.H.O. said. In Congo's Ituri province, where the outbreak was first identified, 246 suspected cases and 80 deaths attributed to the virus had been reported, although only eight cases had been definitively linked to the virus through laboratory testing. There is no approved vaccine and no therapeutics for the Bundibugyo species of Ebola behind the outbreak, according to the W.H.O. The scale of the outbreak could be far larger than has been detected and reported, the W.H.O. said in declaring a "public health emergency of international concern." It added that there were "significant uncertainties" about the precise number of people infected and the "geographic spread." The W.H.O.'s declaration signals a public health risk requiring a coordinated international response, and is intended to prompt member countries to prepare for the virus to spread and to share vaccines, treatments and other resources needed to contain the outbreak. [...] The risk of the outbreak spreading is exacerbated by a humanitarian crisis, high population mobility and a large network of informal health care facilities in the area, the agency said. Containing an Ebola outbreak depends on the speed and scale of the public health response. The virus is transmitted through direct contact with the bodily fluids of an infected person, putting family members and caregivers at particular risk. Tracing people who may have come into contact with sufferers, isolating and treating victims promptly and safely, and burying the dead properly are all viewed as critical steps.

  • Steven Soderbergh Defends AI Use in His New Documentary about John Lennon
    by EditorDavid on 18/05/2026 at 11:34 am

    John Lennon's last interview — just hours before he was shot on December 8, 1980 — has become a documentary directed by Steven Soderbergh, debuting Saturday at the Cannes Film Festival. In a new interview with the Associated Press, Soderbergh defends the film's limited use of AI to visualize concepts from that two-hour interview with John Lennon and Yoko Ono: Soderbergh was resolved to let the audio play. He could finds ways to visualize much of the film, but that still left a large gap where the conversation grows more philosophical. "I worked on everything that could be solved except that for as long as I could," Soderbergh says. "Then there was the inevitable moment of: OK, but really what are we going to do? We just started playing and ran out of time and money. That's where the Meta piece came in." Soderbergh accepted an offer to use Meta's artificial intelligence software to conjure surreal imagery for those sections, which make up about 10% of the film. When Soderbergh let the news out earlier this year, it prompted an uproar. One of America's leading filmmakers was using AI? In a film about a Beatle, no less? The AI parts (overwhelmingly slammed by critics in Cannes) are fairly banal and don't differ greatly from special effects — there are no deepfakes of Lennon. But they put Soderberg at the forefront of an industrywide debate about the uses of AI in moviemaking. It's a conversation the director, who has made movies on iPhones, is eager to have. While the film follows John and Yoko's conversation, "I needed a way to follow them in flight visually," Soderbergh says, "or I'm not doing my job." Though when asked about the strong negative reaction, Soderbergh acknowleges that "I knew what was coming. I take it very seriously, and I understand why people have an emotional response to this subject. As I've said before, I feel like I owe people the best version of whatever art I'm trying to make and total transparency about how I'm doing it." AP: Some fear generative AI will tear apart the film industry. You don't see it as a bogeyman, though. SODERBERGH: I think most jobs that matter when you're making a movie cannot be performed by this tech and never will be performed by this tech. As it becomes possible for anybody to create something that meets a certain standard of technical perfection, then imperfection becomes more valuable and more interesting. We haven't seen yet someone with a certain amount of creative credibility go full-metal AI on something, and see how people react. I think it's necessary. How do you know where the line is until somebody crosses it? "I don't think what I'm doing crosses it. Some people may disagree. I don't know where my line is yet. I'm waiting to see...

  • Iran Now Threatens Fees for Subsea Internet Cables in the Strait of Hormuz
    by EditorDavid on 18/05/2026 at 7:34 am

    Iran's government "wants to charge the world's largest tech companies for using the subsea internet cables laid under the Strait of Hormuz," reports CNN. Their article also notes that Iran's state-linked media outlets "have vaguely threatened that traffic could be disrupted if firms don't pay." Lawmakers in Tehran discussed a plan last week which could target submarine cables linking Arab countries to Europe and Asia. "We will impose fees on internet cables," Iranian military spokesperson Ebrahim Zolfaghari declared on X last week. Iran's Revolutionary Guards-linked media said Tehran's plan to extract revenue from the strait would require companies like Google, Microsoft, Meta, and Amazon to comply with Iranian law while submarine cable companies would be required to pay licensing fees for cable passage, with repair and maintenance rights given exclusively to Iranian firms. Some of these companies have invested in the cables running through the Strait of Hormuz and the Persian Gulf, but it's unclear if those cables traverse Iranian waters. It's also unclear how the regime could force tech giants to comply, as they are barred from making payments to Iran due to strict US sanctions; as a result, the companies themselves may view Iran's statements as posturing rather than serious policy. Still, state-affiliated media outlets have issued veiled threats warning of damage to cables that could impact some of the trillions of dollars in global data transmission and affect worldwide internet connectivity... Iran's threats are part of a strategy to demonstrate its leverage over the Strait of Hormuz and ensure the survival of the regime, a core objective for the Islamic Republic in this war, said Dina Esfandiary, Middle East lead at Bloomberg Economics. "It aims to impose such a hefty cost on the global economy that no-one will dare attack Iran again," she said. The article notes that subsea cables "carry vast internet and financial traffic between Europe, Asia and the Persian Gulf," and that targetting them "would affect far more than internet speeds, threatening everything from banking systems, military communications and AI cloud infrastructure to remote work, online gaming and streaming services." CNN spoke to Mostafa Ahmed, "a senior researcher at the United Arab Emirates-based Habtoor Research Center, who published a paper on the effects of a large-scale attack on submarine communications infrastructure in the Gulf." Armed with combat divers, small submarines, and underwater drones, the Islamic Revolutionary Guard Corps (IRGC) poses a risk to underwater cables, Ahmed said, adding that any attack could trigger a cascading "digital catastrophe" across several continents. Iran's neighbors across the Persian Gulf could face severe disruptions to internet connection, potentially impacting critical oil and gas exports as well as banking. Beyond the region, India could see a large proportion of its internet traffic affected, threatening its huge outsourcing industry with losses amounting to billions, according to Ahmed... Any disruption could also slow financial trading and cross-border transactions between Europe and Asia, while parts of East Africa could face internet blackouts. And if Iran's proxies decide to employ similar tactics in the Red Sea, the damage could be far worse. Read more of this story at Slashdot.

  • Linus Torvalds: AI-Detected Bug Reports Make Kernel Security List 'Almost Entirely Unmanageable'
    by EditorDavid on 18/05/2026 at 3:34 am

    Today Linus Torvalds announced another Linux release candidate on the kernel mailing list. But he also highlighted "documentation updates" to address a new problem. "The continued flood of AI reports has basically made the security list almost entirely unmanageable, with enormous duplication due to different people finding the same things with the same tools." (The new documentation says the security team has found "bugs discovered this way systematically surface simultaneously across multiple researchers, often on the same day.") TORVALDS: People spend all their time just forwarding things to the right people or saying "that was already fixed a week/month ago" and pointing to the public discussion. Which is all entirely pointless churn, and we're making it clear that AI-detected bugs are pretty much by definition not secret, and treating them on some private list is a waste of time for everybody involved — and only makes that duplication worse because the reporters can't even see each other's reports. AI tools are great, but only if they actually help, rather than cause unnecessary pain and pointless make-believe work. Feel free to use them, but use them in a way that is productive and makes for a better experience. The documentation may be a bit less blunt than I am, but that's the core gist of it. The new documentation offers this overview. "It turns out that the majority of the bugs reported via the security team are just regular bugs that have been improperly qualified as security bugs due to a lack of awareness of the Linux kernel's threat model." "So just to make it really clear," Torvalds said at the end of his post. "If you found a bug using AI tools, the chances are somebody else found it too. "If you actually want to add value, read the documentation, create a patch too, and add some real value on *top* of what the AI did. Don't be the drive-by 'send a random report with no real understanding' kind of person. Ok?" Read more of this story at Slashdot.

  • America's Library of Congress Officially Inducts... the Soundtrack for the Videogame 'Doom'
    by EditorDavid on 18/05/2026 at 1:34 am

    America's Library of Congress "is preserving a little piece of Hell," jokes Engadget, "by inducting the soundtrack to the original Doom into the National Recording Registry." The album of demon-slaying tracks is joined by several other notable 2026 additions to the registry, like Weezer's self-titled debut album (colloquially known as "The Blue Album"), Taylor Swift's "1989," Beyonce's "Single Ladies (Put a Ring On It) and the original "Mambo No. 5." "Doom" was created by Bobby Prince, a freelance composer who worked on lots of id Software games, and also scored Doom's '90s rival Duke Nukem 3D. The soundtrack draws clear inspiration from metal bands, but also touches on techno and ambient music throughout its track list, making for an eclectic soundscape for tearing through enemies. That it all fits together is also impressive in its own right: All of the music for Doom was written before the game had completed levels to play through, according to Prince. The official announcement from the Library of Congress says Doom "brought a heavy metal energy to MS-DOS systems across the globe," while also pioneering first-person shooter videogames. "Key to Doom's popularity was the adrenaline-fueled soundtrack created by freelance video game music composer Bobby Prince. Prince, a lifelong musician and practicing lawyer, was fascinated by the MIDI technology that rose in prominence in the mid-1980s as a means for instrument control and composition... For "Doom," Prince took inspiration from a pile of CDs loaned by the game's chief designer, John Romero, including seminal works by Alice in Chains, Pantera and Metallica. Despite the limitations of the 1993-era sound card drivers, Prince composed the perfect riff-shredding accompaniment for the game's demon-slaying journey to hell and back. Taking advantage of his knowledge of MIDI, Prince even worked to ensure that the sound effects he created could cut through the music by assigning them to different MIDI frequencies.

  • Former Google CEO Eric Schmidt Booed During Graduation Speech About AI
    by EditorDavid on 17/05/2026 at 11:46 pm

    Today former Google CEO Eric Schmidt "was booed multiple times," reports NBC News, "while discussing AI during a commencement speech at the University of Arizona." Schmidt had started by remembering how computer platforms "gave everyone a voice" but also "degraded the public square... They rewarded outrage. They amplified our worst instincts. They coarsen the way we speak to each other, and that way, and in the way that we treat each other, is in the essence of a society." But then Schmidt "drew a parallel between artificial intelligence and the transformative impact of the computer — and was immediately met with boos." "I know what many of you are feeling about that. I can hear you," Schmidt said, addressing the crowd as many continued to boo him. "There is a fear ... there is a fear in your generation that the future has already been written, that the machines are coming, that the jobs are evaporating, that the climate is breaking, that politics is fractured, and that you are inheriting a mess that you did not create, and I understand that fear." He went on to argue that the future remains unwritten and that the graduating class of 2026 has real power to shape how AI develops — a claim that drew further disapproval from parts of the audience... He closed by congratulating the class and offering them closing words. "The future is not yet finished. It is now your turn to shape it." 404 Media shared a video on YouTube of the crowd's booing — and what Schmidt said that provoked them: SCHMIDT: "If you don't care about science that's okay because AI is going to touch everything else as well. [Very loud booing] Whatever path you choose, AI will become part of how work is done..." "You can now assemble a team of AI agents to help you with the parts that you could never accomplish on your own. [Loud booing] When someone offers you a seat on the rocket ship, you do not ask which seat. You just get on... The rocket ship is here." Read more of this story at Slashdot.
