Anthropic announces discovery of new enzyme system resembling CRISPR

Anthropic has announced the discovery of a new enzyme system in bacterial DNA that may represent a new gene editing mechanism similar to CRISPR. The company stated on Wednesday that its AI model, Claude, autonomously discovered the system while researchers were working at its biology research lab in San Francisco. The system exhibits characteristics found in only a few other programmable structures and shows a pattern reminiscent of CRISPR, a genome-editing mechanism found in bacteria. CRISPR technology has been credited with advancing the treatment of various diseases, including sickle cell disease and cancer. Anthropic noted that it has not yet determined the function of the newly discovered system, which Claude identified after 21 hours of searching a large database of DNA sequences. CEO Dario Amodei expressed optimism about the potential of AI in medical discoveries, stating that it is at the beginning of making significant advancements. Stanley Qi, an associate professor of bioengineering at Stanford University, described the discovery as exciting, highlighting AI's ability to recognize complex biological patterns. However, microbiologist Kevin Blake expressed skepticism regarding the significance of the announcement, cautioning against assuming that the discovery is a rival to CRISPR technology. He noted that many CRISPR-like sequences remain unidentified due to the vast number of bacterial species yet to be studied. Emmanuelle Charpentier and Jennifer Doudna, who pioneered the CRISPR gene-editing system, were awarded the 2020 Nobel Prize in Chemistry for their work. Last year, the Children’s Hospital of Philadelphia reported a historic medical breakthrough using customized CRISPR gene-editing therapy to treat a patient with a rare metabolic disease.
