On the design front, the model ach...

The researchers introduce CompBioBench, a new evaluation framework containing 100 diverse tasks designed to test the capabilities of agentic AI systems in computational biology. Because biological data is often noisy and lacks simple answers, the benchmark uses synthetic data and scrambled metadata to create objective problems that require multi-step reasoning, coding, and tool use. Evaluation of...

ROCKET addresses these gaps by optimi...

The article introduces the Random Neighbor Score (RNS), a model-agnostic framework designed to measure the reliability of protein language model (pLM) embeddings. While these computational representations are vital for predicting biological functions and structures, the authors argue that embedding uncertainty often goes unquantified, leading to erroneous downstream scientific insights. To address...
