Atlas 2: Foundation models built for clinical pathology

Meet Atlas 2 — a new family of pathology vision foundation models designed to close the gap to clinical deployment.

Why it matters: Previous models often forced a trade-off between accuracy, robustness, and compute cost. Atlas 2, Atlas 2-B, and Atlas 2-S aim to balance all three.

Trained on 5.5 million histopathology whole-slide images from Charité – Universitätsmedizin Berlin, LMU Munich, and Mayo Clinic — the largest dataset of its kind.
Tested across 80 public benchmarks with state-of-the-art prediction performance, robustness, and resource efficiency.
Multiple sizes to fit real-world constraints, from high-performance to compute-friendly.

Big picture: More reliable and efficient pathology AI could help labs scale quality control, triage, and research workflows — moving trustworthy AI closer to the clinic.

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
