  • DuckDuckGo Installs Up 30% After Google Announced AI Search
    by EditorDavid on 30/05/2026 at 5:34 pm

    After Google announced AI-emphasizing changes to its search results, many web surfers began defecting to DuckDuckGo, reports TechCrunch. (They describe DuckDuckGo as "a privacy-focused alternative" that accounts for around 2% of the U.S. search market...) DuckDuckGo said U.S. app installs went up 18.1% week-over-week on average during the May 20 to May 25 period, compared to May 13 to May 18. The company said that growth was sustained for six consecutive days and peaked at 30.5% on May 25. On iOS, the rate of install is even higher, with week-over-week growth hitting a 33% average, peaking at 69.9%... DuckDuckGo said the trend is stronger in the U.S, and that DuckDuckGo continued to gain users over the Memorial Day weekend, when it usually sees a dip in traffic. Some of that data is backed up by third parties. App analytics company Apptopia found a 29% increase in average daily downloads in the U.S. and a 12% increase globally over the same period. DuckDuckGo also said visits to its AI-free search page, noai.duckduckgo.com averaged 22.7% week-over-week growth, peaking at 27.7% on May 24, according to the article. ("DuckDuckGo also offers an AI Image Filter that filters out AI-created images from search results.") TechCrunch delves into the reason why: I overheard a woman on the phone saying she was switching to DuckDuckGo because you can "opt out of using AI... Google just isn't Google anymore," she said. It seems that others had the same idea... Some have argued it will kill the open web, while others shared concerns that AI overviews surface inaccurate responses and take away control from users who might not want to use AI. It also overcomplicates simple things. A Google spokesperson pointed out that AI Mode isn't the default in their search results. (And CNET notes Google include an AI-free "Web" choice in its results if you just want a page of ftraditional blue links.) TechCrunch adds that DuckDuckGo also offers a separate free tool called Duck.ai offering access to models including Claude, Meta's Llama and OpenAI's GPT-5 mini. "All chats are private because DuckDuckGo strips the user's IP address before requests reach model providers, deletes conversations within 30 days, and prevents chats from being used for training."

  • Ozempic May Be Reshaping the Brain, Scientists Say
    by EditorDavid on 30/05/2026 at 4:34 pm

    A research team found "extensive changes" on brain scans of 13 young women taking GLP-1 drugs, reports the Washington Post: Within only a few months, the brain connections in the salience network, which helps target attention, had multiplied... ["We didn't expect to see this effect, and we really don't know what it means," said an assistant professor assisting the research.] Ozempic and other GLP-1 drugs were initially understood as a metabolism breakthrough: medicines that act like hormones to control hunger, blood sugar and weight. But as researchers probe deeper into how the drugs work, early evidence suggests that GLP-1s may also be reshaping parts of the brain. Tens of millions of people are now taking the medications worldwide, turning what began as an obesity and diabetes treatment into what could be modern medicine's largest unplanned neuroscience experiments... Long before Oprah Winfrey and social media influencers helped popularize GLP-1 drugs, physician-scientist Lorenzo Leggio was studying them as a possible addiction treatment... Several major studies examining GLP-1 drugs on nicotine dependence, opioid- and cocaine-use disorders, gambling addiction and binge eating are also underway. "It's very exciting times, but we don't fully understand how it works," Leggio said... As evidence has grown that inflammation, metabolism and mental health may be far more connected than scientists once believed, researchers have become intrigued by patients who say GLP-1 drugs appear to ease anxiety, compulsive thinking and emotional distress. Daniel Drucker, a University of Toronto researcher and GLP-1 drug pioneer who receives funding from several drugmakers, said researchers are investigating the medications across a variety of psychiatric and neurological conditions, though none are approved for them. "We have so many anecdotal reports: They were treated for blood sugar and then they felt much happier. Or they took one dose of the drug and their brain fog cleared," he said. The article suggests social media complaints "raise deeper questions about what, exactly, these drugs are changing. "If GLP-1s alter the brain systems involved in reward, craving and motivation, researchers wonder, where is the line between quieting a person's destructive impulses and reshaping personality itself?"

  • Software Stocks Have Best Month Since 2001. Talk of 'SaaSpocalypse' Subsides
    by EditorDavid on 30/05/2026 at 3:34 pm

    Security company Okta shot up 30% Friday, reported CNBC, while data platform provider Snowflake jumped 50% this week. They see it as part of a larger trend where software stocks "soared this week," signaling "some companies are navigating their way through AI disruption better than Wall Street expected" and that investors "may have been too quick to declare the end of software with the emergence of AI. Even as AI displaces certain tools and job functions, many software companies continue to show growth, assisted by their own AI products..." The "SaaSpocalypse" may not be over. But for now at least, fears of software's demise have cooled... The iShares Expanded Tech-Software exchange-traded fund rose 8% this week and closed May up 21%, the best monthly performance for the ETF since October 2001. Back then it was a brief rebound during the dot-com bust, while the current rally comes as concerns about the impact of AI ripple across the sector. Software names have been hit particularly hard over the past year due to the boom in so-called vibe coding, with users able to now build apps and websites in minutes thanks to offerings from Anthropic, OpenAI and others... Elsewhere in the software space, Atlassian climbed 26% for the week and ServiceNow surged over 20%, while Shopify, Workday and Asana each gained at least 14%. Read more of this story at Slashdot.

  • US Aims to Give Cold War Plutonium to Startups For Nuclear Fuel
    by BeauHD on 30/05/2026 at 11:34 am

    The Trump administration is planning to provide Cold War-era plutonium from dismantled nuclear warheads to nuclear startups that want to convert it into reactor fuel, arguing it could help address a looming fuel shortage for advanced reactors. Critics warn the idea raises serious nonproliferation, security, cost, and technical concerns. The New York Times reports: The plan has generated debate and some unease among nonproliferation experts. If finalized, it would mark the first time the U.S. government has made weapons-grade plutonium available to private companies. The Energy Department has more than 50 tons of surplus plutonium left over from nuclear weapons programs, and the agency had previously been planning to dilute much of that material and bury it. Some of the nuclear start-ups trying to obtain that plutonium say that transforming the waste into fuel is a better way to dispose of it. On Tuesday, the Energy Department said that it had selected five companies to enter into "advanced negotiations" to potentially receive some surplus plutonium. That includes Oklo, a California-based nuclear power company, which plans to partner with Newcleo, a European developer of advanced nuclear reactors. Using plutonium for fuel, Oklo and Newcleo said, could solve a looming problem: Energy firms want to build a new wave of nuclear reactors, but the United States can't yet make enough conventional fuel from uranium to supply the plants. Harvesting old plutonium stockpiles could provide a short-term fix. "A lack of fuel is one of the biggest choke points in expanding nuclear power right now," said Jacob DeWitte, the chief executive of Oklo, which is developing a novel type of small reactor intended to run on plutonium. "This will help us get more nuclear power online faster." [...] The plan is not yet final, and companies will still have to negotiate with the federal government over how to secure and transfer the plutonium. In addition to Oklo, the Energy Department said it had also selected four other companies -- Standard Nuclear, Exodys Energy, SHINE Technologies and Flibe Energy -- to enter into advanced negotiations to receive the material under its Surplus Plutonium Utilization Program, which was established last year. The program "is anticipated to help companies unlock the next level of private funding to broaden domestic nuclear fuel supplies, spur innovation on American recycling technologies, and unlock private sector funding to fuel the nation's nuclear renaissance," said Michael Goff, the principal deputy assistant secretary of nuclear energy, in a statement.

  • Apple Working To Cram Massive Gemini Model Into iPhone To Power New Siri
    by BeauHD on 30/05/2026 at 8:00 am

    Apple is reportedly working to shrink Google's Gemini models enough to power parts of a long-delayed AI-enhanced Siri on iPhones. But despite Apple's best efforts to run the AI locally, "the iPhone's Gemini makeover will lean heavily on Google and Nvidia in the cloud," reports Ars Technica. That could complicate Apple's privacy-first AI messaging, especially if more complex Siri requests are routed through Google infrastructure and Nvidia's encrypted cloud-computing platform. Ars Technica reports: After inking the Google deal, Apple apparently got to work distilling Google's giant cloud-based Gemini models. Distillation is a process in which a small, less resource-intensive model learns to mimic a large, expensive one. With enough time, this can reliably transfer useful capabilities while pruning less important weights from the model. That may enable Siri to handle some tasks with private local compute, but a cloud component looks inevitable. Processing users' AI data in the cloud could be a problem for Apple. At WWDC, the company will probably promote its years of experience designing chips and how well that positions it for AI. However, The Information claims that Apple has struggled to even get Google's massive undistilled Gemini models running on its custom Private Cloud Compute infrastructure, which is built on on M-series Mac chips. When the smarter Siri rolls out, it will probably route more complex tasks to Google's cloud infrastructure instead of Apple's, but it won't be running on Google TPUs. Apple has reportedly signed a deal with Nvidia to use its Confidential Computing platform for this purpose. Confidential Computing keeps data encrypted on Nvidia GPUs while it's being processed in the cloud, which could help Apple claim it's still sensitive to user privacy concerns. It might even retain its own Private Cloud Compute branding for the system. The iPhone probably won't tell you which version of Gemini is handling individual Siri requests. Device makers designing hybrid systems that rely on local and cloud-based AI like to talk about making the experience feel "seamless." There might be clues, though.

  • RIP: Marcia Lucas, Oscar-Winning Star Wars Editor, Dies At 80
    by EditorDavid on 30/05/2026 at 3:30 am

    ```Long-time Slashdot reader schwit1 brings word that Marcia Lucas, part of the editing team for both Star Wars and Return of the Jedi, has died at age 80 after a battle with metastatic cancer. Married to George Lucas from 1969 to 1983, Marcia is remembered by The Wrap as "a powerful asset in the early days of the Star Wars series, helping shape its voice and identity long before it became the massive global franchise..." She won an Academy Award for Best Film Editing for her work on the original "Star Wars" movie, an award that came four years after she was nominated for editing George's previous film, "American Graffiti." She additionally edited his debut feature, "THX 1138." Beyond these collaborations with her then-husband, Marcia worked as an editor with other acclaimed filmmakers like Martin Scorsese and Francis Ford Coppola. She was credited as sole editor for Scorsese's "Alice Doesn't Live Here Anymore," and served as supervising editor for "Taxi Driver" and "New York, New York." Marcia served as part of a three-person crew editing both "Star Wars" and "Return of the Jedi." On the first film, she worked alongside Paul Hirsch and Richard Chew and was personally responsible for editing the Battle of Yavin — otherwise known as the iconic "trench run" sequence near the end of the film. For "Return of the Jedi," Marcia shared credit with Sean Barton and Duwayne Dunham. "If only Lucas had people like her on the prequels instead of sycophants who worshipped him as a God..." argues this 2015 blog post noting an article calling her "the secret weapon behind Star Wars — including this anecdote from The Secret History of Star Wars : The [Star Wars] Death Star trench run was originally scripted entirely different, with Luke having two runs at the exhaust port; Marcia had re-ordered the shots almost from the ground up, trying to build tension lacking in the original scripted sequence, which was why this one was the most complicated (Deleted Magic has a faithful reproduction of the original assembly, which is surprisingly unsatisfying). She warned George, "If the audience doesn't cheer when Han Solo comes in at the last second in the Millennium Falcon to help Luke when he's being chased by Darth Vader, the picture doesn't work."
