GCT: new AI method turns brain-prediction black boxes into testable linguistic theories

Microsoft Research and partners developed Generative Causal Testing (GCT), which distills LLM-based brain-prediction models into concise verbal explanations (e.g., “food preparation”) and then uses an LLM to write new stories that causally test those explanations in fMRI. GCT confirmed known selectivity, disentangled neighboring place-processing regions, and discovered tiny prefrontal zones for dialogue, clock times, and measurements.

Memora: A Harmonic Memory Representation Balancing Abstraction and Specificity

Microsoft Research introduces Memora, an agentic memory system that decouples rich memory content from lightweight retrieval abstractions, achieving state-of-the-art performance on long-context benchmarks while using up to 98% fewer tokens. The system uses primary abstractions and cue anchors to balance detail and efficiency, enabling AI agents to sustain long-term collaboration.
