  • Electric Cars Are Making It Easier To Breathe, Study Finds
    by msmash on 10/02/2026 at 3:45 am

    An anonymous reader shares a report: It turns out that when fewer cars spew exhaust as they drive along, air quality improves. That's the conclusion of a new study published in The Lancet Planetary Health that looked at the effect of increased numbers of both EVs and plug-in hybrids on air pollution in California. The Golden State has by far the largest number of plug-in vehicles in the United States, and they've now reached significant numbers to have a positive impact on air quality. Between 2019 and 2023, for every 200 EVs or plug-in hybrids added, nitrogen dioxide (NO2) levels dropped 1.1%, according to the study, which used satellite data to track those levels through the unique way NO2 absorbs and reflects sunlight. NO2 can trigger asthma attacks, cause bronchitis, and increase the risk of heart disease and stroke. Read more of this story at Slashdot.

  • Kalshi Prediction Markets Match or Beat Traditional Forecasting Tools For Macro Indicators, NBER Study Finds
    by msmash on 10/02/2026 at 1:45 am

    A new NBER working paper from researchers at the Federal Reserve, Northwestern's Kellogg School and Johns Hopkins finds that Kalshi -- the largest federally regulated prediction market in the U.S., overseen by the CFTC -- produces macroeconomic forecasts that match or beat those of professional forecasters and traditional financial instruments like fed funds futures. The study compared Kalshi-implied forecasts for the federal funds rate, CPI inflation and unemployment against the New York Fed's Survey of Market Expectations and Bloomberg consensus. Kalshi's modal forecast correctly predicted the federal funds rate on the day before every FOMC meeting since 2022, something neither the survey nor fed funds futures achieved. For headline CPI, Kalshi's median and mode produced a statistically significant improvement over Bloomberg consensus. Kalshi also fills a gap no other financial market covers: real-time probability distributions for GDP growth, core CPI, unemployment, and payrolls. The paper documented how these distributions shift in response to macro news -- positive CPI surprises moved the mean of the fed funds rate distribution four times more than negative ones. Trading volumes on the platform have grown to nearly 100 million contracts for a single FOMC meeting, supported by liquidity from Susquehanna, Citadel, and Two Sigma.

  • Linux 7.0 Kernel Confirmed By Linus Torvalds, Expected In Mid-April 2026

    An anonymous reader writes: Linus Torvalds has confirmed the next major kernel series as Linux 7.0, reports Linux news website 9to5Linux.com: "So there you have it, the Linux 6.x era has ended with today's Linux 6.19 kernel release, and a new one will begin with Linux 7.0, which is expected in mid-April 2026. The merge window for Linux 7.0 will open tomorrow, February 9th, and the first Release Candidate (RC) milestone is expected on February 22nd, 2026." Read more of this story at Slashdot.

  • OpenAI Starts Running Ads in ChatGPT
    by msmash on 09/02/2026 at 9:00 pm

    OpenAI has started testing ads inside ChatGPT for logged-in adult users on the Free and Go subscription tiers in the United States, the company said. The Plus, Pro, Business, Enterprise and Education tiers remain ad-free. Ads are matched to users based on conversation topics, past chats, and prior ad interactions, and appear clearly labeled as "sponsored" and visually separated from ChatGPT's organic responses. OpenAI says the ads do not influence ChatGPT's answers, and advertisers receive only aggregate performance data like view and click counts rather than access to individual conversations. Users under 18 do not see ads, and ads are excluded from sensitive topics such as health, mental health, and politics. Free-tier users can opt out of ads in exchange for fewer daily messages.

  • Sixteen AI Agents Built a C Compiler From Scratch
    by msmash on 09/02/2026 at 8:00 pm

    Anthropic researcher Nicholas Carlini set 16 instances of Claude Opus 4.6 loose on a shared codebase over two weeks to build a C compiler from scratch, and the AI agents produced a 100,000-line Rust-based compiler capable of building a bootable Linux 6.9 kernel on x86, ARM and RISC-V architectures. The project ran through nearly 2,000 Claude Code sessions and cost about $20,000 in API fees. Each instance operated inside its own Docker container, independently claiming tasks via lock files and pushing completed code to a shared Git repository. No orchestration agent directed traffic. The compiler achieved a 99% pass rate on the GCC torture test suite and can compile major open source projects including PostgreSQL, SQLite, Redis, FFmpeg and Doom. But it lacks a 16-bit x86 backend and calls out to GCC for that step, its assembler and linker remain buggy, and it produces less efficient code than GCC running with all optimizations disabled. Carlini also invested significant effort building test harnesses and feedback systems to keep the agents productive, and the model hit a practical ceiling at around 100,000 lines as bug fixes and new features frequently broke existing functionality.

  • Romance Publishing Has an AI Problem and Most Readers Don't Know It Yet
    by msmash on 09/02/2026 at 7:01 pm

    The romance genre -- long the publishing industry's earliest adopter of technological shifts, from e-books to self-publishing to serial releases -- has become the front line for AI-generated fiction, and the results as you can imagine are messy. Coral Hart, a Cape Town-based novelist previously published by Harlequin and Mills & Boon, produced more than 200 AI-assisted romance novels last year and self-published them on Amazon, where they collectively sold around 50,000 copies. She found Anthropic's Claude delivered the most elegant prose but was terrible at sexy banter; other programs like Grok and NovelAI wrote graphic scenes that felt rushed and mechanical. Chatbots struggled broadly to build the slow-burn sexual tension romance readers crave, she said. A BookBub survey of more than 1,200 authors found roughly a third were using generative AI for plotting, outlining, or writing, and the majority did not disclose this to readers. Romance accounts for more than 20% of all adult fiction print sales, according to Circana BookScan, and the genre's reliance on familiar tropes and narrative formulas makes it especially susceptible to AI disruption.
