High-dimensional dynamical systems can operate in two regimes: effective dynamics with simplified models, and a more complex regime without effective dynamics. Modern global systems are transitioning from predictable patterns to more uncertain, nonlinear states where traditional models may fail. Complex challenges require nuanced solutions that combine simplified models with awareness of their limitations and diverse human expertise.

UNC-Chapel Hill researchers discovered that loggerhead sea turtles can learn and remember specific magnetic signatures associated with feeding locations, demonstrating their ability to create a magnetic map. The study reveals two distinct mechanisms for magnetic navigation in turtles - a map sense for location and a compass sense for direction - which may have evolved separately.

AI agents from OpenAI, Anthropic, and BrowserBase can now navigate websites like human users, presenting both opportunities and security risks for applications. Legacy detection methods are proving ineffective against these sophisticated agents, with most websites currently unable to detect or block their traffic. Testing reveals varying levels of detectability across different AI agent toolkits, with some capable of bypassing even strict security measures.
