Anthropic announced on Wednesday that its AI model Claude discovered a new enzyme system in bacterial DNA similar to the CRISPR gene-editing mechanism after searching a large database of DNA sequences for 21 hours. The company suggests this could represent a novel gene editing tool, though its exact function is still unknown. Experts like Stanford's Stanley Qi view the finding as promising for AI-assisted biological discovery, while others, such as microbiologist Kevin Blake, caution against overstating its significance.

Story summary
Anthropic, an AI company based in San Francisco, announced on September 23 the discovery of a new enzyme system by its AI model Claude. The finding is similar to CRISPR technology and could represent a new gene-editing mechanism. Anthropic's biology lab used more than 950 autonomous AI agents, which combed through over 200,000 genes within 21 hours, identifying about 20 that warrant further investigation—a task that would typically take months for human scientists.
The discovery involves a pattern in bacterial DNA consisting of repeating pieces of DNA next to two genes, one known and another mysterious. This system shows characteristics of only a few other programmable structures and displays patterns reminiscent of CRISPR, which has revolutionized the treatment of diseases like sickle cell disease and cancer. Anthropic emphasized that its role was primarily in setting up initial instructions and conducting follow-up lab experiments, while Claude autonomously identified the leads.
This breakthrough underscores AI's potential to accelerate scientific discovery significantly and highlights ongoing debates about managing the risks and benefits associated with advanced AI technologies globally.
