New publication out @natcomms.nature.com! We identify novel viruses that actively infect highly productive chemoautotrophs, and reveal key trophic interactions and virus-host dynamics that impact microbial carbon cycling in aphotic environments.

Extensive array of endogenous giant viral elements in a polar alga shows dynamic transcriptional response to abiotic stress Schultz et al. show that polar algae harbor extensive endogenous giant virus elements that are transcriptionally active, stress responsive, and integrated into host regulatory networks, highlighting v...

I am excited to share our new preprint on how iron limitation leads to cascading impacts on diatom carbon exudation and subsequent uptake and processing by heterotrophic bacteria. 🌊🦠

Sub-daily virus sampling at the Bermuda Atlantic Time Series reveals diel and depth-structured population dynamics without community-level shifts Viruses are often studied in disease settings, but in the ocean they outnumber cells and shape ecosystems, yet their dynamics remain poorly understood. In this study, high-resolution sampling of blue-...

Bermuda Atlantic Time Series surface waters contain thousands of viral populations with diel rhythms, forming “archetypes” that vary in abundance patterns, predicted hosts, taxonomy, and gene functions @sullivan-lab.bsky.social @joshuasweitz.bsky.social

Viruses in marine sediments: a review of their effect on biogeochemistry and microbial interactions | Applied and Environmental Microbiology In the ocean, viruses are known to mediate the carbon cycle, keeping dissolved organic carbon (DOC) in the microbial loop and preventing its movement into secondary consumers (1). However, few direct ...

New paper out! We sat down and compiled all viral work in marine sediments. The water column has been getting a second look for viral interactions, its time for sediment to have the same!

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

That’s unfortunate! I would love to try a handheld peristaltic pump 😊

I need to know more! Is this is a custom design of yours?

Science in action... a research cruise to explore marine viruses & their microbial hosts made possible by NSF support and held together by the talents of @negilbert.bsky.social (now at Syracuse U) and Daniel Muratore (now at SFI), @camelia-s-gochev.bsky.social (of Technion) & many more...

Viruses aren’t all bad: In the ocean, some help fuel the food web – a new study shows how Marine viruses attack cells, but the material that spills out helps fuels marine life around the world.

New with @tn-marine-micro.bsky.social, exploring how viral-mediated infection and lysis can fuel the marine food web:

Our paper on how viral lysis may influence system biogeochemistry in the Sargasso Sea subsurface oxygen max (SOM) is finally published! Thanks to all coauthors and especially @tn-marine-micro.bsky.social for providing the opportunity to work on this project integrating field work and modeling

congrats @atruch.bsky.social !! Can’t wait to read it

Introducing ** Incendiamoeba **, a eukaryote that can live at temperatures well beyond what we thought possible. 63C!!

Read @hbrappap.bsky.social thread to see what we’ve already started to learn from this amazing organism!
