Meet EWE: An AI Weather Expert for Extreme Events

Extreme weather is getting worse, but understanding the physical “why” behind each event still takes weeks of expert detective work. Forecasting AI has improved, yet diagnostic reasoning — explaining causes — has lagged.

Enter EWE (Extreme Weather Expert), a new AI agent that acts like a meteorologist-in-the-loop. EWE plans analyses, reasons in closed loops, and uses a domain-specific toolkit to turn raw atmospheric data into maps, plots, and plain-language explanations — automatically.

Emulates expert workflows with knowledge-guided planning
Generates and interprets multimodal visualizations
Performs end-to-end diagnostic analyses from raw data

First benchmark: 103 high-impact events + a stepwise metric to test scientific reasoning.

Why it matters: faster, more consistent event diagnostics can accelerate discovery and help agencies — especially in developing nations — triage risks and resources when extreme weather strikes.

Meet GRACE: a moral governor for safer, more transparent AI

AI agents are getting powerful—so how do we make sure they do the right thing, not just the effective thing? Meet GRACE, a reason-based moral governor that keeps AI behavior aligned with human norms by separating moral reasoning from goal-driven decision-making. * Moral Module: uses deontic logic and explicit reasons

Why some fine-tuned LLMs miss phishing—and how to fix it

Not all fine-tuned LLMs spot phishing equally. A new study tests Llama 3.1 8B, Gemma 2 9B, and Mistral on high-stakes phishing detection—and uses SHAP and mechanistic interpretability to reveal why models do (or don’t) generalize. * Architecture × data diversity matters: Gemma 2 9B hits state-of-the-art performance (F1

AI that explains itself—by following the science

AI that explains itself—by following the science Black-box AI can be powerful, but it often can’t tell us why it made a decision. Concept Bottleneck Models (CBMs) try to fix that by predicting human-understandable concepts first, then the final answer. The catch: standard CBMs ignore domain-specific cause-and-effect and

Meet GenomAgent: A Team of AI Specialists for Smarter Genomics Q&A

TL;DR: Finding reliable answers in genomics is hard. GenomAgent turns one big AI into a coordinating team of specialists—and beats the current leader by 12% on a key benchmark. Genomic facts live across many databases. Standard chatbots struggle because they can’t flexibly query those sources. GeneGPT added
