KAUST researchers found that sulfate ions reduce free water in aqueous batteries, mitigating parasitic reactions that degrade the anode and shorten battery life. Adding zinc sulfate increased battery lifespan by more than ten times. Sulfate salts stabilize the bonds of free water, acting as a "water glue" to reduce parasitic reactions. Why it matters: This finding provides a cheap and scalable approach to improve the viability of aqueous batteries for sustainable energy storage, particularly for integrating renewable energy sources.
Saudi Arabia's national AI authority, SDAIA (Saudi Data and AI Authority), is reportedly developing a National AI Index. This index aims to measure and track the Kingdom's progress and capabilities across various dimensions of artificial intelligence. It is expected to encompass areas such as research and development, talent, infrastructure, and ethical considerations. Why it matters: This initiative provides a crucial framework for evaluating Saudi Arabia's AI ecosystem, guiding future strategic investments, and benchmarking its national AI capabilities against international standards.
Researchers introduce UnsafeChain, a new safety alignment dataset designed to improve the safety of large reasoning models (LRMs) by focusing on 'hard prompts' that elicit harmful outputs. The dataset identifies and corrects unsafe completions into safe responses, exposing models to unsafe behaviors and guiding their correction. Fine-tuning LRMs on UnsafeChain demonstrates enhanced safety and preservation of general reasoning ability compared to existing datasets like SafeChain and STAR-1.
