An expert at the University of Copenhagen said his team had been sharing its research with the company’s A.I. model, Claude, and that its new finding matched their work.

Anthropic is an AI safety and research company that's working to build reliable, interpretable, and steerable AI systems.

The T7 bacteriophage deactivates bacterial defence systems through T7K phosphorylation of nearly all host and phage proteins during infection.

ContactSeek is an AlphaFold3-driven model that can improve the precision of genome-editing tools.

Retrons are prokaryotic genetic elements that protect bacterial cells from invading phages. The type IX retron comprises a non-coding RNA, a reverse transcriptase (RT), and dual effectors: a putative ...

The rapid evolution of plant pathogens poses a persistent threat to global agricultural sustainability, often outpacing the discovery and deployment of natural disease resistance genes. While bioengin...

OLD, an abortive immunity protein from prophage P2, consists of an ABC ATPase sensor and a TO-PRIM nuclease effector - a core architecture shared by a large protein family, including components of ant...

As an organization, Google maintains a portfolio of research projects driven by fundamental research, new product innovation, product contribution and infrastructure goals, while providing individuals...

DNA repair proteins are repeatedly repurposed for antiviral immunity. In this issue of Cell Host & Microbe, Bell et al. utilized phylogenetic reconstruction of the evolutionary routes of the YprA repa...

Magnesium serves as an essential cofactor for small GTPases, yet its structural role in regulating KRAS conformational dynamics and nucleotide exchange remains poorly understood. Here, we combine hyd....

Germinal achieves epitope-targeted, de novo complementarity-determining region design with high experimental success rates.

The activation of an antiphage defence system relies on host factors targeted by phages, a mechanism analogous to the way that eukaryotic innate immune systems detect pathogen-induced perturbations of...

Norway is taking steps to limit how generative AI can be used in schools from the start of the next school year.

CRISPR-Cas adaptive immunity systems provide defense against mobile genetic elements and are often countered by diverse anti-CRISPR (Acr) proteins....

Folddisco enables protein structural motif search in million scale databases.

Changes to government’s vaccine purchase system after 2024 revolution led to nationwide shortages, gaps in immunity

Hany Farid, who's spent his career building tools to detect fake images, is facing his biggest challenge yet: AI

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Nature Microbiology, Published online: 27 April 2026; doi:10.1038/s41564-026-02312-8A large-scale, comparative cell biology and biochemical screen defines the molecular features controlling antiphage defence systems that encode nuclease effectors and accessory NTPase proteins.

Nature Reviews Microbiology, Published online: 23 April 2026; doi:10.1038/s41579-026-01306-xComprehensive assessment of the host range of phages is a prerequisite for their safe and effective use in multiple applications but is rarely undertaken. This Review outlines the molecular and ecological determinants of phage host range and discusses the importance of these determinants for developing phage-based applications.
