The firm says it plans to back companies across AI applications, infrastructure, healthcare, fintech, and security. Meanwhile, Microsoft Research published a major update to MatterSim, its AI system for materials science. The company says the platform now supports faster simulation, experimental synthesis validation, and new multi-task modeling capabilities designed to move AI-assisted scientific discovery closer to practical research workflows. In research, we look at MEME — Multi-entity & Evolving Memory Evaluation — a new benchmark examining whether AI agents can reliably remember, update, and reason across long-running interactions. The results suggest current agent memory systems remain fragile, especially when facts evolve or depend on one another over time. In the headlines: Meta tests deeper AI integration inside Threads, OpenAI highlights AI-assisted research workflows through Parameter Golf, Simon Willison explores new OpenAI reasoning APIs and secure sandbox tooling, and Amazon continues to leave the door open to future AI-focused hardware experiments.
