New open-source Python-based software boosts space-weather modeling

University of Birmingham experts have created open-source computer software that helps scientists understand how fast-moving particles behave when they interact with electromagnetic waves in space. Understanding how these particles behave in Earth’s radiation belts is crucial because high-energy electrons can damage satellites, while radiation belt dynamics affect space weather forecasts. Better models help protect astronauts,…

OpenAI starts offering a biology-tuned LLM

To address LLMs’ tendencies toward sycophancy and overenthusiasm, OpenAI says it has tuned the model to be more skeptical, so it’s more likely to tell you when something is a bad drug target. There was a lot of talk about GPT-Rosalind’s “reasoning” and “expert-level” abilities. We were told that the former was defined as being…

Astronomers spotted a pair of monster black holes that could collide in just 100 years — and Earth will feel it

Astronomers may have discovered an extreme pair of light-spewing black holes that are spiraling toward an enormous collision — the effects of which could be felt in the next century. Using decades of radio telescope observations, the astronomers studied an ultrabright object that was previously thought to be a blazar — a glowing core of…
