Anthropic's Claude AI autonomously identified a previously unknown enzyme system in bacteriophage DNA that includes a reverse transcriptase gene flanked by a long array of CRISPR-like repeats, which the researchers have termed array-associated reverse transcriptases (ART). The finding demonstrates that large language models can generate novel scientific hypotheses and uncover biological systems with potential applications in gene editing and synthetic biology, highlighting AI's growing role in accelerating discovery. It also raises discussions about AI safety, as such capabilities could be misused to design harmful genetic constructs. The system centers on a reverse transcriptase enzyme from a jumbo phage, accompanied by a tandem repeat array resembling CRISPR arrays; although its biochemical function remains unknown, the combination of RT and repeat architecture has only been observed in a few other programmable nucleic‑acid‑modifying systems. Claude identified the pattern by analyzing raw DNA sequences and noting the repeat structure "by eye."
Italy's parliament passed legislation to lift the decades‑old ban on nuclear energy, focusing on small modular reactors (SMRs) and other advanced technologies, though it does not yet authorize reactor construction. The move marks a major policy shift in a key European economy, potentially diversifying Italy’s energy mix and boosting interest in SMRs across NATO allies. The legislation creates the regulatory framework needed for future SMR projects but does not authorize any immediate construction; Italy’s nuclear ban originated from a 1987 referendum after the Chernobyl disaster.
