      Researchers claim breakthrough in fight against AI’s frustrating security hole

      news.movim.eu / ArsTechnica • 16 April

    In the AI world, a vulnerability called "prompt injection" has haunted developers since chatbots went mainstream in 2022. Despite numerous attempts to solve this fundamental vulnerability—the digital equivalent of whispering secret instructions to override a system's intended behavior—no one has found a reliable solution. Until now, perhaps.

    Google DeepMind has unveiled CaMeL (CApabilities for MachinE Learning), a new approach to stopping prompt-injection attacks that abandons the failed strategy of having AI models police themselves. Instead, CaMeL treats language models as fundamentally untrusted components within a secure software framework, creating clear boundaries between user commands and potentially malicious content.

    Prompt injection has created a significant barrier to building trustworthy AI assistants, which may be why general-purpose big tech AI like Apple's Siri doesn't currently work like ChatGPT. As AI agents get integrated into email, calendar, banking, and document-editing processes, the consequences of prompt injection have shifted from hypothetical to existential. When agents can send emails, move money, or schedule appointments, a misinterpreted string isn't just an error—it's a dangerous exploit.

      Looking at the Universe’s dark ages from the far side of the Moon

      news.movim.eu / ArsTechnica • 16 April

    There is a signal, born in the earliest days of the cosmos. It’s weak. It’s faint. It can barely register on even the most sensitive of instruments. But it contains a wealth of information about the formation of the first stars, the first galaxies, and the mysteries of the origins of the largest structures in the Universe.

    Despite decades of searching for this signal, astronomers have yet to find it. The problem is that our Earth is too noisy, making it nearly impossible to capture this whisper. The solution is to go to the far side of the Moon, using its bulk to shield our sensitive instruments from the cacophony of our planet.

    Building telescopes on the far side of the Moon would be the greatest astronomical challenge ever considered by humanity. And it would be worth it.

      Autism rate rises slightly; RFK Jr. claims he’ll “have answers by September“

      news.movim.eu / ArsTechnica • 15 April

    The rate of autism in a group of 8-year-olds in the US rose from 2.76 percent (1 in 36) in 2020 to 3.22 percent (1 in 31) in 2022, according to a study out Tuesday in the Morbidity and Mortality Weekly Report , a journal published by the Centers for Disease Control and Prevention.

    The report's authors—researchers at the CDC and academic institutions across the country— suggest that the slight uptick is likely due to improved access to evaluations in underserved groups, including Black, Hispanic, and low-income communities.

    The data comes from the CDC-funded Autism and Developmental Disabilities Monitoring (ADDM) Network. The national network has been tracking the prevalence of autism spectrum disorder (ASD) in 8-year-olds at a handful of sites since 2000, publishing estimates every two years. In 2000, ASD prevalence was 1 in 150, with white children from high-income communities having the highest rates of the developmental disability. In 2020, when the rate hit 1 in 36, it was the first year in which higher ASD rates were seen in underserved communities. That year, researchers also noted that the link between ASD and socioeconomic status evaporated in most of the network.

      Google adds Veo 2 video generation to Gemini app

      news.movim.eu / ArsTechnica • 15 April

    Google has announced that yet another AI model is coming to Gemini, but this time, it's more than a chatbot. The company's Veo 2 video generator is rolling out to the Gemini app and website, giving paying customers a chance to create short video clips with Google's allegedly state-of-the-art video model.

    Veo 2 works like other video generators, including OpenAI's Sora —you input text describing the video you want, and a Google data center churns through tokens until it has an animation. Google claims that Veo 2 was designed to have a solid grasp of real-world physics, particularly the way humans move. Google's examples do look good, but presumably that's why they were chosen.

    Prompt: Aerial shot of a grassy cliff onto a sandy beach where waves crash against the shore, a prominent sea stack rises from the ocean near the beach, bathed in the warm, golden light of either sunrise or sunset, capturing the serene beauty of the Pacific coastline.

      White House calls NPR and PBS a “grift,” will ask Congress to rescind funding

      news.movim.eu / ArsTechnica • 15 April

    The Trump White House is proposing to eliminate most federal funding for National Public Radio (NPR) and the Public Broadcasting Service (PBS) and issued a statement yesterday alleging that NPR and PBS "spread radical, woke propaganda disguised as 'news.'"

    "The NPR, PBS grift has ripped us off for too long," the White House statement said.

    White House budget director Russ Vought drafted a memo for a rescission plan that would eliminate funding already approved by Congress, according to multiple news reports. This includes $1.1 billion for the Corporation for Public Broadcasting (CPB), or about two years' worth of funding for the nonprofit group that provides money to public broadcasting stations.

      The physics of bowling strike after strike

      news.movim.eu / ArsTechnica • 15 April • 1 minute

    More than 45 million people in the US are fans of bowling, with national competitions awarding millions of dollars. Bowlers usually rely on instinct and experience, earned through lots and lots of practice, to boost their strike percentage. A team of physicists has come up with a mathematical model to better predict ball trajectories, outlined in a new paper published in the journal AIP Advances. The resulting equations take into account such factors as the composition and resulting pattern of the oil used on bowling lanes, as well as the inevitable asymmetries of bowling balls and player variability.

    The authors already had a strong interest in bowling. Three are regular bowlers and quite skilled at the sport; a fourth, Curtis Hooper of Longborough University in the UK, is a coach for Team England at the European Youth Championships. Hooper has been studying the physics of bowling for several years, including an analysis of the 2017 Weber Cup, as well as papers devising mathematical models for the application of lane conditioners and oil patterns in bowling.

    The calculations involved in such research are very complicated because there are so many variables that can affect a ball's trajectory after being thrown. Case in point: the thin layer of oil that is applied to bowling lanes, which Hooper found can vary widely in volume and shape among different venues, plus the lack of uniformity in applying the layer, which creates an uneven friction surface.

      4chan has been down since Monday night after “pretty comprehensive own”

      news.movim.eu / ArsTechnica • 15 April

    Infamous Internet imageboard and wretched hive of scum and villainy 4chan was apparently hacked at some point Monday evening and remains mostly unreachable as of this writing. DownDetector showed reports of outages spiking at about 10:07 pm Eastern time on Monday, and they've remained elevated since.

    Posters at Soyjack Party , a rival imageboard that began as a 4chan offshoot, claimed responsibility for the hack. But as with all posts on these intensely insular boards, it's difficult to separate fact from fiction. The thread shows screenshots of what appear to be 4chan's PHP admin interface, among other screenshots, that suggest extensive access to 4chan's databases of posts and users.

    Security researcher Kevin Beaumont described the hack as "a pretty comprehensive own" that included "SQL databases, source, and shell access." 404Media reports that the site used an outdated version of PHP that could have been used to gain access, including the phpMyAdmin tool, a common attack vector that is frequently patched for security vulnerabilities . Ars staffers pointed to the presence of long-deprecated and removed functions like mysql_real_escape_string in the screenshots as possible signs of an old, unpatched PHP version.

      Netflix plans to bring streaming into the $1 trillion club by 2030

      news.movim.eu / ArsTechnica • 15 April

    Netflix plans to reach a market capitalization of $1 trillion by 2030 , The Wall Street Journal (WSJ) reported this week, citing anonymous people who attended an “annual business review meeting” that Netflix held in March. Netflix's current market capitalization is nearly $400 billion.

    Netflix is reportedly partnering its market cap goals with plans to double revenue within the same time frame. For 2024, Netflix reported $39 billion in revenue, meaning the company aims to raise its annual revenue to $78 billion in five years.

    Compared to the prior five years, Netflix’s revenue grew 93.5 percent from 2019 ($20.16 billion) to 2024. However, that time period represented a different market, one where streaming subscriber counts were rising rapidly, and Netflix faced less competition than it does today. However, Netflix's 2030 revenue goals are also dependent on its advertising business, something Netflix lacked in 2019.

      Here’s how a satellite ended up as a ghostly apparition on Google Earth

      news.movim.eu / ArsTechnica • 15 April

    Dig deep on Google Earth and you'll inevitably find a surprise or two. Maybe you're looking at far-flung islands in the middle of an ocean or checking in on something closer to home.

    A few years ago, online sleuths found an image of a B-2 stealth bomber in flight over Missouri. The aircraft is smeared in the image because it was in motion, while the farm fields below appear as crisp as any other view on Google Earth.

    There's something else that now appears on Google Earth. Zoom in over rural North Texas, and you'll find a satellite. It appears five times in different colors, each projected over wooded bottomlands in a remote wildlife refuge about 60 miles (100 kilometers) north of Dallas.
