New developments in artificial intelligence and brain activity research are making headlines, alongside ongoing geopolitical concerns. A new study on meditation's impact on the brain, advancements in large language models (LLMs), and the U.S.'s claims of secret nuclear tests by China are among the latest developments.
Researchers from the University of Montreal and Italy's National Research Council found that meditation is a state of heightened cerebral activity, not one of rest, according to a study published by Wired. They analyzed the brain activity of 12 monks of the Thai Forest Tradition using magnetoencephalography (MEG).
Meanwhile, the AI landscape continues to evolve. Chinese AI startup z.ai unveiled its new large language model, GLM-5, which achieves a record-low hallucination rate, according to VentureBeat. The model, which retains an open-source MIT License, scored -1 on the AA-Omniscience Index, a 35-point improvement over its predecessor, demonstrating superior knowledge reliability. Additionally, MIT researchers developed a new technique called self-distillation fine-tuning (SDFT) that allows LLMs to learn new skills without forgetting past capabilities, as reported by VentureBeat. This method outperforms traditional supervised fine-tuning and addresses limitations of reinforcement learning.
The emergence of AI assistants also continues. An independent software engineer, Peter Steinberger, created OpenClaw, a tool that allows users to create their own bespoke assistants by harnessing existing LLMs. The project went viral in late January, according to MIT Technology Review.
In other news, the U.S. has accused China of conducting secret nuclear tests, as reported by NPR Politics. The U.S. claims China may be developing new nuclear warheads for its hypersonic weapons.
