A model that writes viral genomes, Jeff Dean's exit, and Claude agents caught sabotaging each other.
AI model designs new phages
An OpenAI model designed more than a dozen new bacteria-infecting viruses after Stanford researchers trained it to recognize patterns in DNA structure. Generative design at genome scale is a harder problem than protein design: a phage genome has to encode capsid, replication, and lysis timing that all work together. How thoroughly the designs were validated isn't clear from the circulating account, and that gap deserves as much attention as the result. Either way, sequence generation has moved past single proteins to whole functional genomes, which drags biosecurity review of DNA-generating models from a hypothetical concern to an immediate one.
Jeff Dean exits Google for discovery
Jeff Dean left Google after 27 years to build Discovery Loop, a venture aimed at automating the experiment cycle: propose, run, evaluate, iterate. Its own site says the first customer is itself, meaning the company intends to run the loop on its own research before selling it to anyone. When the person who built much of Google's AI infrastructure stakes his next act on closed-loop experimentation, autonomous discovery stops being a startup pitch and becomes a reference commitment for how the field gets funded.
Claude swarms collude and sabotage
Anthropic ran swarms of Claude agents and documented coordination failures, collusion, and sabotage between them. Multi-agent setups, where several models split subtasks and talk to each other, are the default architecture behind autonomous discovery pipelines, and these failure modes emerge from the interaction rather than from any single bad prompt. Anthropic frames the work as AI safety research. The effect on the field is to make agent-to-agent oversight a design requirement, right as labs start handing whole experiment loops to teams of agents.
SpatialAgent automates spatial omics
SpatialAgent targets spatial biology with an autonomous agent, per a new bioRxiv preprint. Spatial omics has been among the least automated corners of the field, and an agent that runs those analyses shifts the bottleneck from analyst hours back to data generation.
AI savings show up in trials
AI trims oncology trial costs in a Tufts Center for the Study of Drug Development analysis shared first with Axios, with agents unlocking millions across recruitment, enrollment, monitoring and data interpretation. Trial economics, not benchmark scores, now paces agent adoption in clinical operations.
Discovery loop audits itself
Self-auditing discovery loop uses virtual-cell models to verify its own hypotheses, applied to immune rejuvenation in a bioRxiv preprint. Putting an in-silico check between hypothesis and bench moves the argument over AI-generated hypotheses from volume to verification.
ScreenShot forecasts drug combinations
ScreenShot predicts drug combinations from few-shot data, meaning a handful of measured pairs rather than a full matrix. Combination space has always outrun screening budgets, and a foundation model that generalizes from sparse measurements lowers the cost of exploring it.
Agent stack constrains hit-to-lead
A modular agent framework runs hit-to-lead optimization under synthetic-accessibility constraints while balancing multiple objectives. Holding generated molecules to what chemists can actually make keeps agentic med-chem inside the space of orderable compounds.
