Mild aortic dilation: 12% caught on first reads, 93% with a measuring VLM
Aortic dilation is rarely quantified on chest X-rays, and mild cases get missed: 5 of 43 on initial reads. A tool-augmented VLM caught 40. New CARE-X research explains why radiology AI needs rulers, not just eyes.

Microsoft's experiential learning fix gives AI models a coach, not just a score
Experiential Learning repurposes the LLM-as-a-Judge into an LLM-as-a-Coach that extracts transferable knowledge from each response and internalizes it via on-policy context distillation, beating rubric-based RL on held-out tasks and reducing reward hacking.

Neuroscience
The neuroscience AI that finally cracks open the brain's black box
Generative causal testing (GCT) distills LLM-based brain-prediction models into concise verbal explanations, then uses an LLM to write stories that causally test those claims in fMRI. In experiments, GCT confirmed known selectivity, teased apart neighboring place-processing regions, and discovered new prefrontal micro-regions tuned to concepts like dialogue and measurements.

Bing found a 12,000-line allocator that breaks a 50-year-old trade-off
Microsoft Research's mimalloc allocator uses thousands of per-page free lists and a clever page-stealing technique to achieve both high concurrency and low memory overhead, breaking a trade-off that constrained systems for decades. A deep-dive from the RiSE group reveals the design.

AI Agents
Microsoft's bet on small models for agentic AI is about orchestration, not knowledge
Microsoft Research's MagenticLite project shows that small models can handle complex agentic tasks when orchestration, model design, and execution environment are codesigned. The release includes MagenticBrain, a 14B orchestrator, and Fara1.5, a computer-use model family that nearly doubles prior performance on web navigation benchmarks.

Microsoft's Flint hides the chart boilerplate so AI agents stop drawing wrong axes
Microsoft Research introduced Flint, a visualization intermediate language that helps LLMs and AI agents create polished charts without hand-coding low-level parameters like scales and axis formatting. In a study across three models, Flint outperformed direct Vega-Lite generation, and is already used internally in Data Formulator.

Nature Neuroscience paper
Microsoft's new method turns black-box brain AI into readable theories
GCT translates uninterpretable LLM-based brain models into short phrases like 'food preparation' or 'location names,' then uses an LLM to write stories that causally test those explanations in real subjects. The method promises to bridge predictive AI and human-readable scientific theory.

Microsoft just opened a codebase that kills the worst part of enterprise data work
Data Formulator 0.7 is an open-source AI system from Microsoft Research that helps enterprise teams connect fragmented data sources, prepare and analyze data with context-aware agents, and iteratively refine visualizations in a shared workspace, all without requiring SQL or programming skills.

mimalloc, Microsoft's tiny memory workhorse, is quietly powering AI at scale
Microsoft Research's mimalloc memory allocator, designed for high concurrency and large memory scales, is quietly powering AI and cloud services at scale. Its thread-local design with thousands of free lists minimizes contention and delivers both speed and memory efficiency.
