• Peter Thiel and Balaji Srinivasan have provided seed funding for the “Enhanced Games Olympics,” a proposed competition that would allow unrestricted use of performance-enhancing technologies.  
• OpenAI dropped the price of ChatGPT-3.5-Turbo to $0.50 per million tokens, prompting criticism that the cheaper model is significantly less useful than the retired text-davinci-003 and lacks GPT-4-level completion endpoints.  
• Discussion on personal stimulant optimization: participants debated how to determine an individual’s ideal morning caffeine dose, noting wide variability in tolerance, metabolism, and downstream effects on dopamine vs. acetylcholine signaling.  
• A new Science paper (DOI: 10.1126/science.adk8511) shows that blood-pressure pulsations modulate central neuronal activity through mechanosensitive ion channels, adding another physiological variable that future brain–computer interfaces may need to emulate or compensate for.  
• Two open-source CAD/CAM resources were shared: “ocp-freecad-cam” (a bridge between OpenCASCADE and FreeCAD for tool-path generation) and the “cq_warehouse” repository, a curated collection of parametric parts built with the CadQuery framework.
