📣 A new preprint by noashima.bsky.social! 📣 How does ocean warming affect viral infection? Infection of algae by a giant virus is arrested intracellularly under elevated temperature, with the late replication stage blocked. Infection can later resume, revealing a reversible arrest state 🌊

Reversible inhibition of viral life cycle in response to elevated temperature in a bloom-forming alga

Ocean warming is expected to reshape microbial interactions and community composition, with profound consequences for marine biogeochemical cycles. Host virus dynamics are central to these processes, ...

🌊Paper announcement! 📣 Viral infections rewire the metabolic makeup of their host and thereby create distinct chemical signatures. Can we use metabolic biomarkers to diagnose infections of algal blooms in the ocean? Well, take a look at our new article led by Conny Kuhlisch in @pnas.org >>

Mapping of the viral shunt across widespread coccolithophore blooms using metabolic biomarkers | PNAS

The viral shunt is a fundamental ecosystem process which diverts the flux of organic carbon fixed through photosynthesis during algal bloom events ...

📣A new preprint by Talia Shaler! 📣 How do populations develop resistance to viral infections? We mapped the transcriptomic landscape of algal resistance to lytic viral infection and identified a unique set of resistance-related genes expressed in those cells >> doi.org/10.1101/2025...
