Did Anthropic Really Make a Big Biology Breakthrough? We Asked Scientists to Weigh In

Anthropic's AI Claude recently made waves by identifying an enzyme system that had never been observed before. While this breakthrough is certainly noteworthy, some scientists remain skeptical about the significance of this discovery. The enzyme in question is a CRISPR-like system, discovered while Claude was examining approximately 200,000 reverse transcriptase samples. In comparison, conducting this research manually would have taken humans months.

Anthropic claims that human involvement was limited to providing prompts and conducting lab work, while a fleet of 950 AI agents scoured publicly available databases to uncover the novel enzyme. The system was identified within 21 hours and subsequently confirmed by human scientists to be genuinely unique. The enzyme, named "array-associated reverse transcriptases" or ART, was found in a bacteriophage, a virus that specifically targets bacteria.

CRISPR, the discovery for which Anthropic is being celebrated, is a defense mechanism employed by bacteria to combat viral infections. This mechanism involves copying viral DNA snippets into the bacterium's DNA, creating a library of these snippets over generations. When a virus attacks the bacterium, the bacterium uses a RNA strand associated with the viral snippet to guide a cutting protein that can neutralize the virus, thereby stopping its replication and killing the infection.

ART, on the other hand, is a distinct discovery that, while similar to CRISPR in some ways, represents a new system with its own unique properties. However, some researchers are cautious about the potential impact of this discovery, pointing out that it took nearly two decades to fully understand CRISPR and develop the first CRISPR-based medicine. Thus, it remains to be seen if ART will prove to be a significant breakthrough in biological research.
