  • Opera Wants You To Pay $20 a Month For Its AI Browser
    by msmash on 11/12/2025 at 2:45 pm

    Opera has opened its AI-powered browser Neon to the public after a couple of months of testing, and anyone interested in trying it will need to pay $19.90 per month. The Norway-based company first unveiled Neon in May and launched it in early access to select users in October. Like Perplexity's Comet, OpenAI's Atlas, and The Browser Company's Dia, Neon bakes an AI chatbot into its interface that can answer questions about pages, create mini apps and videos, and perform tasks. The browser uses your browsing history as context, so you can ask it to fetch details from a YouTube video you watched last week. The subscription also grants access to AI models including Gemini 3 Pro and GPT-5.1. Read more of this story at Slashdot.

  • US Could Ask Foreign Tourists For Five-Year Social Media History Before Entry
    by msmash on 11/12/2025 at 2:05 pm

    Tourists from dozens of countries including the UK could be asked to provide a five-year social media history as a condition of entry to the United States, under a new proposal unveiled by American officials. From a report: The new condition would affect people from dozens of countries who are eligible to visit the US for 90 days without a visa, as long as they have filled out an Electronic System for Travel Authorization (ESTA) form. Since returning to the White House in January, President Donald Trump has moved to toughen US borders more generally - citing national security as a reason. Analysts say the new plan could pose an obstacle to potential visitors, or harm their digital rights. Asked whether the proposal could lead to a steep drop-off in tourism to the US, Trump said he was not concerned. "No. We're doing so well," the president said on Wednesday. "We just want people to come over here, and safe. We want safety. We want security. We want to make sure we're not letting the wrong people come enter our country."

  • New OpenAI Models Likely Pose 'High' Cybersecurity Risk, Company Says
    by BeauHD on 11/12/2025 at 1:00 pm

    An anonymous reader quotes a report from Axios: OpenAI says the cyber capabilities of its frontier AI models are accelerating and warns Wednesday that upcoming models are likely to pose a "high" risk, according to a report shared first with Axios. The models' growing capabilities could significantly expand the number of people able to carry out cyberattacks. OpenAI said it has already seen a significant increase in capabilities in recent releases, particularly as models are able to operate longer autonomously, paving the way for brute force attacks. The company notes that GPT-5 scored a 27% on a capture-the-flag exercise in August, GPT-5.1-Codex-Max was able to score 76% last month. "We expect that upcoming AI models will continue on this trajectory," the company says in the report. "In preparation, we are planning and evaluating as though each new model could reach 'high' levels of cybersecurity capability as measured by our Preparedness Framework." "High" is the second-highest level, below the "critical" level at which models are unsafe to be released publicly. "What I would explicitly call out as the forcing function for this is the model's ability to work for extended periods of time," said OpenAI's Fouad Matin. Read more of this story at Slashdot.

  • Sperm Donor With Cancer-Causing Gene Fathered Nearly 200 Children Across Europe
    by BeauHD on 11/12/2025 at 10:00 am

    schwit1 shares a report from CBS News: perm from a donor who unknowingly carried a cancer-causing gene has been used to conceive nearly 200 babies across Europe, an investigation by 14 European public service broadcasters, including CBS News' partner network BBC News, has revealed. Some children conceived using the sperm have already died from cancer, and the vast majority of those who inherited the gene will develop cancer in their lifetimes, geneticists said. The man carrying the gene passed screening checks before he became a donor at the European Sperm Bank when he was a student in 2005. His sperm has been used by women trying to conceive for 17 years across multiple countries. The cancer-causing mutation occurred in the donor's TP53 gene -- which prevents cells in the body from turning cancerous -- before his birth, according to the investigation. It causes Li Fraumeni syndrome, which gives affected people a 90% chance of developing cancers, particularly during childhood, as well as breast cancer in later life. Up to 20% of the donor's sperm contained the mutated TP53 gene. Any children conceived with affected sperm will have the dangerous mutation in every cell of their body. The affected donor sperm was discovered when doctors seeing children with cancers linked to sperm donation raised concerns at this year's European Society of Human Genetics. At the time, 23 children with the genetic mutation had been discovered, out of 67 children linked to the donor. Ten of those children with the mutation had already been diagnosed with cancer. Freedom of Information requests submitted by journalists across multiple countries revealed at least 197 children were affected, though it is not known how many inherited the genetic mutation. More affected children could be discovered as more data becomes available. Read more of this story at Slashdot.

  • NASA Loses Contact With MAVEN Mars Orbiter
    by BeauHD on 11/12/2025 at 7:00 am

    NASA has lost contact with its MAVEN Mars orbiter after it passed behind Mars. When it remerged from behind the planet, the spacecraft never resumed communications. SpaceNews reports: MAVEN launched in November 2013 and entered orbit around Mars in September 2014. The spacecraft's primary science mission is to study the planet's upper atmosphere and interactions with the solar wind, including how the atmosphere escapes into space. That is intended to help scientists understand how the planet changes from early in its history, when it had a much thicker atmosphere and was warm enough to support liquid water on its surface. MAVEN additionally serves as a communications relay, using a UHF antenna to link the Curiosity and Perseverance rovers on the Martian surface with the Deep Space Network. NASA's Mars Odyssey and Mars Reconnaissance Orbiter spacecraft also serve as communications relays for the rovers, but are both significantly older than MAVEN. The spacecraft has suffered some technical problems in the past, notably with its inertial measurement units (IMUs) used for navigation. In 2022, MAVEN switched to an "all-stellar" navigation system to minimize the use of the IMUs. MAVEN has enough propellant to maintain its orbit through at least the end of the decade. NASA's fiscal year 2026 budget proposal, though, zeroed out funding for MAVEN, which cost $22.6 million to operate in 2024. MAVEN was one of several missions "operating well past the end of prime mission" the proposal would terminate, despite MAVEN's role as a communications relay. Read more of this story at Slashdot.

  • ChatGPT Is Apple's Most Downloaded App of 2025
    by BeauHD on 11/12/2025 at 3:30 am

    An anonymous reader quotes a report from TechCrunch: Apple on Wednesday released its annual list of the most downloaded apps and games for the year. For the U.S. market, OpenAI's ChatGPT topped the ranks of free iPhone apps (not including games) with the most installs in 2025. The AI app was followed by Threads, Google, TikTok, WhatsApp, Instagram, YouTube, Google Maps, Gmail, and Google's Gemini. ChatGPT made it to No. 4 last year, but the top spot was taken by Chinese shopping app Temu. In 2023, the AI app didn't make the top-10 list despite being released on the iPhone in May 2023 to a strong debut. Read more of this story at Slashdot.
