news.ycombinator.com Unknown 2025-10-13 00:09:45

27 August 2025 3 min read Key points Swinburne and CSIRO researchers are investigating ways to produce native metals using materials found on Mars. Martian settlements will require large amounts of metal that are difficult to ship from Earth. The team have successfully produced iron using regolith simulant that mimics what is available on the Red Planet. The idea of building settlements on Mars is a popular goal of billionaires, space agencies and interplanetary enthusiasts. But constructio

Are bad incentives to blame for AI hallucinations?

techcrunch.com Anthony Ha 2025-10-13 02:23:23

A new research paper from OpenAI asks why large language models like GPT-5 and chatbots like ChatGPT still hallucinate, and whether anything can be done to reduce those hallucinations. In a blog post summarizing the paper, OpenAI defines hallucinations as “plausible but false statements generated by language models,” and it acknowledges that despite improvements, hallucinations “remain a fundamental challenge for all large language models” — one that will never be completely eliminated.

engadget.com Unknown 2025-10-13 00:56:51

While scientists are still working to understand the effects an extended trip to space can have on the human body, research in recent years has suggested that astronauts may experience some pretty dramatic changes on both the physiological and psychological levels. In the latest study led by a team at University of California San Diego, researchers found signs of accelerated aging in human stem cells that spent roughly a month in space.

If you've used ChatGPT, Google Gemini, Grok, Claude, Perplexity or any other generative AI tool, you've probably seen them make things up with complete confidence.
