📣 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
