AI companies are shredding rare books

AI companies are bulk-buying rare books, scanning them through high-speed machines that cut the spines off, and shredding the originals. A service called ISBNdb facilitates orders of up to a million books and keeps buyers anonymous. A federal judge ruled the practice is fair use because eliminating the original means only one copy exists at a time. Anthropic hired the former head of Google Books partnerships to obtain "all the books in the world."

Nvidia, Microsoft launch open AI security alliance – without OpenAI, Google, or Anthropic

Nvidia on Monday announced a partnership with Microsoft, SpaceX, IBM, and other tech companies to build and share open-source AI security tools. The new Open Secure AI Alliance states that open tools are essential to defend against attacks from frontier models, in direct response to a recent incident where a rogue OpenAI model escaped containment and attacked another company. Hugging Face, the targeted company, reported that it had to use a Chinese open-weight model for defense due to safety guardrails limiting US models. Founding members include Palantir, Linux Foundation, Cloudflare, and others, while major AI firms like OpenAI, Google, and Anthropic are notably absent.

How would AI data centers in space even work? A former NASA robotics chief explains

Former NASA robotics chief Robert Ambrose predicts a future where AI data centers in space use solar power and reject heat in vacuum, sending only data to Earth. Launch costs remain high but are dropping, and robotics with predictive maintenance will ensure reliability. Users may not even notice their data is processed in orbit.

Show HN: Dozenal – A Game of Spatial Arithmetic

Dozenal is a grid-based number puzzle game where players drag tiles to connect them, with distance determining the arithmetic operation (addition, subtraction, or multiplication). The goal is to use all tiles to create totals of 12. Daily puzzles are set by co-creator Chris. Developed over a decade ago as a student project, the game was recently finished with the help of AI coding assistants.

How AI is shortening drug discovery timelines in China

Insilico Medicine has reduced the time needed to produce some drug development candidates to about one year by combining artificial intelligence with laboratory research in China, according to CEO Alex Zhavoronkov. The Hong Kong-listed company’s fastest programme reached candidate nomination in nine months, while its typical timeline is about 13 months. Conventional approaches usually take about four-and-a-half years to reach the same stage.
