A new peer-reviewed study cut AI-redesigned toxin genes into fragments and fed them to four commercial DNA screening tools. Two caught fragments as short as 50 nucleotides. Here's what that means ten weeks before a US screening deadline — and why the authors are still worried.
Everything else from the field.
Genome sequencing published this week places the virus behind Central Africa's fastest-growing Ebola outbreak on a distinct branch of the Bundibugyo family tree — with an evolutionary signal nobody expected. Here is what that means for diagnostics built on the wrong prior, and where AI-assisted sequencing genuinely helps.
OpenAI is giving 100,000 academic researchers free frontier model access with 75+ life science skills. Anthropic's newest flagship refuses to explain mitochondria. Both companies claim to be managing the same biosecurity risk — and the gap between their answers tells you how unsettled AI-for-biology governance really is.
A multimodal benchmark of 322 expert-validated questions finds OpenAI's o3 outperforms 94% of PhD virologists on troubleshooting complex lab protocols. We unpack what changed, what it doesn't prove, and why pandemic-preparedness planners should care.
For about three years, the standard frontier-lab position on biology was defensive. Biology was the scary quadrant of the risk matrix.
