We focused on prasnoviurses infecting Micromonas (MpV), a picoeukaryote genus distributed from poles to tropics. We explored the distribution of isolated MpV-s in Tara datasets and highlighted that temperature is the main descriptor of their community composition. (2/6)

[David Demory @D2mory]

Our results highlight that temperature-driven cellular mechanisms can drive the community dynamics and biogeography of marine viruses.

This multidisciplinary study has been possible through great collaborations involving 3 continents: (5/6)

Delighted to share our new preprint on bioRxiv:

Where we integrated viral metagenomics and mathematical modelling to explore the temperature-driven biogeography of marine giant viruses - where do they live and why? (1/6)

For those working on viruses in aquatic environments, mark your calendars and consider submitting an abstract for Aquatic Virus Workshop 12 (AVW12) to be held in Banyuls-sur-Mer, May 5-9, 2025.

Limited to 125 in total (register early).

It's publication day for "Asymptomatic" via @JHUPress. The book explores the paradox of asymptomatic transmission and rationale for proactive steps to confront future pandemics:

A thread🧵

[Sergi Valverde🌍(under a blue sky) @svalver]

New paper in @nature shows #AI models collapse when trained on their own outputs—repeated AI-generated content leads to redundancy & gibberish. This mirrors our "Dilution of expertise" theory of cultural collapses: "too much imitation kills creativity." https://t.co/qqjY5ZMRKM

Postdoc Dinh @qdinhtran is half way to his destination, the Sorbonne University marine station @OOBanyuls at Bayuls-sur-Mer to present his work at the Arago seminar series: Defective viral genomes of mosquito-borne viruses: parasites or components of viral populations?

He will also set up collaborations with David Demory @D2mory who studies phytoplankton and the infection dynamics of their viruses.

check out their institute's website to dream about nice places that could be your office - better than most commutes to work :

So excited the latest discovery is out on Viral coinfection, Superinfection dominance, and Temperature modulating outcome. Super research by Claudia Meyer! And Vicky Jackson :-)

Excitement is building for the 12th iteration of the Aquatic Virus Workshop to be held at the fantastic Oceanologic Observatory in Banyuls-sur-Mer, France during 5-9 May 2025. We have a great lineup of speakers, and a nascent website: https://t.co/udBBHfGTUm

Delighted to share news of a new @mbiojournal paper from @weitz_group at @UMDscience led by @mariandommi joint w/@D2mory & J. Harris:

"Accounting for cellular-level variation in lysis: implications for virus–host dynamics"

https://t.co/tbnh2glEBk

[Joshua Weitz @joshuasweitz]

More soon... for now, delighted to share news of a @biorxivpreprint led by @mariandommi joint w/@D2mory & J. Harris focusing on the widely used one-step growth curve and how variability in cellular lysis can lead to biases in latent period estimates:

Thank you to @carlzimmer, who's written a very nice synthesis of people studying the dynamics of virus populations and cooperation and cheating of viruses - the sociovirology - including our work at @astar_research @idlabs_astar and with @meletios_tx on using these concepts to create new antiviral interventions.

Nice to see so many colleagues and friends in this article! I wish I were attending the Sociovirology meeting this year! I really need to try and organize one on this side of the world!

New paper from the MuLTEE in @NatureEcoEvo, this one on emergent eco-evolutionary dynamics. Led by @PineauRozenn and @SFI_elibby, we explore how the evolution of multicellularity creates opportunities for ecological niche expansion and coexistence.
